a request acquisition unit that acquires a request for controlling the power storage device;
a determination unit that determines whether or not both of a charged state and a discharged state are included in states of a plurality of power storage devices including the power storage device to be controlled when the power storage device is controlled in accordance with the request acquired by the request acquisition unit; and
and a power storage device control unit that, when the determination unit determines that both the state of charge and the state of discharge are included in the states of the plurality of power storage devices, does not control the power storage device to be controlled when a predetermined condition is not satisfied, and controls the power storage device to be controlled in accordance with the request when the condition is satisfied.
In the present invention, it is determined whether both of the charged state and the discharged state are included in the states of the plurality of power storage devices including the power storage device to be controlled in the case where the power storage device to be controlled is controlled in accordance with the request, and even in the case where both of the charged state and the discharged state are included in the states of the plurality of power storage devices, the power storage device to be controlled is controlled in accordance with the request when a predetermined condition is satisfied. Therefore, according to the present invention, it is possible to flexibly control a plurality of power storage devices according to the situation.

Alternatively, the power generation facility 500 may be in a power generation state or a standby state (non-power generation state).
Specifically, the state acquisition unit 101 acquires the state of each device in accordance with a polling method. That is, the state acquisition unit 101 periodically inquires whether or not data to be sequentially transmitted to each device is present via the in-home network 710 and the in-home interface 17. The instrument that accepts the query returns a response to the query, for example, in the case where the state changes to a different state from the state at the time point at which the query was previously accepted. The state acquisition unit 101 receives a response from the device that has received the inquiry, and thereby acquires information indicating the current state of the device. The status acquisition unit 101 is not limited to the order of polling, and may transmit a status acquisition request to an arbitrary device at an appropriate timing (timing) and acquire information indicating the current status of the device transmitted from the device at the transmission destination as a response to the status acquisition request. Alternatively, for example, when the state of the device changes, the state acquisition unit 101 may acquire the state of each device by actively notifying the control device 100 of the state of the device and receiving the notification. The acquired information indicating the state of each instrument is stored as instrument management data 200 stored in the storage unit 150.
The request acquisition unit 102 acquires a request for control of any device connected to the control apparatus 100, including the 1st power storage device 310 and the 2 nd power storage device 320. The control request is a request for controlling each device in accordance with an operation from a user or in accordance with the operation schedule 230 stored in the storage unit 150, and is, for example, a request for changing the state of each device from the operating state to the standby state or from the charged state to the discharged state. The request acquisition unit 102 acquires a control request by receiving information indicating the content of control from an instrument operated by a user via the home network 710 and the home interface 17, for example. Alternatively, when the date and time determined by the operation schedule 230 arrives, the request acquisition unit 102 acquires a request for control according to the contents of the operation schedule 230, which is supplied via the schedule management unit 109.
When the request acquisition unit 102 acquires a request for control of the 1st power storage device 310 or the 2 nd power storage device 320, the determination unit 103 determines whether or not the combination of the states of the two power storage devices 310 and 320 in the case where the power storage device to be controlled is controlled in accordance with the acquired request matches a previously prohibited combination. As will be described in detail later, the determination criterion 210 for determining that the combination of the states of the two power storage devices 310 and 320 including both the charged state and the discharged state is a prohibited combination is stored in the storage unit 150 in advance. The determination unit 103 refers to the determination criterion 210 stored in the storage unit 150 and executes the determination process.
When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination when the power storage device to be controlled is controlled in accordance with the request, the warning notification unit 104 notifies a warning indicating that the requested control is inappropriate control. The warning reporting unit 104 reports a warning to the user by displaying a warning screen on the touch panel 16, for example.
When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the prohibited combination when the power storage device to be controlled is controlled as required, the power storage device control unit 105 controls the power storage device to be controlled as required. On the other hand, when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination when the determination unit 103 determines to control the power storage device to be controlled in accordance with the request, the power storage device control unit 105 restricts the control of the power storage device to be controlled so that the combination of the states of the two power storage devices 310 and 320 does not become the prohibited combination.
To describe in more detail, when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination when the power storage device to be controlled is controlled in accordance with the request, the power storage device control unit 105 does not control the power storage device to be controlled when the predetermined condition is not satisfied, and controls the power storage device to be controlled in accordance with the request when the predetermined condition is satisfied. As described in detail later, when the request acquisition unit 102 acquires a request for a re-controlled (reordered control) of the power storage device to be controlled after the warning report unit 104 reports the request, this condition is satisfied.
The limitation information generation unit 107 generates limitation information indicating control to be performed to limit a combination of the current states of the two power storage devices 310 and 320 acquired by the state acquisition unit 101. The details of the restriction information will be described later. The restriction information reporting unit 108 reports the restriction information generated by the restriction information generating unit 107 to the user by, for example, displaying the restriction information on the touch panel 16.
In the description of the flowcharts shown in fig. 7, 8, 9, and 12, the functions of each unit included in the control device 100 will be described in more detail.
The storage unit 150 stores the instrument management data 200, the determination criterion 210, and the operation schedule table 230. The instrument management data 200 is data for the control device 100 to manage each instrument provided in the HEMS1000, and stores information indicating the state of each instrument. Determination criterion 210 is data for determining whether the combination of the state of 1st power storage device 310 and the state of 2 nd power storage device 320 is appropriate or inappropriate, that is, whether the combination is to be prohibited. The operation schedule 230 is data on a schedule of operation such as the date and time when the state of charge and discharge is changed, which is determined in advance by the two power storage devices 310 and 320. The user can freely set the operation schedule 230 via the touch panel 16 or the like.
Fig. 4 shows an example of the determination criterion 210. In decision criterion 210, there are settings for 9 combinations of the state (bat1sts) of the 1st power storage device 310 and the state (bat2sts) of the 2 nd power storage device 320 from the 1st combination (line 1) to the 9 th combination (line 9). Then, whether each of the 9 combinations is appropriate or inappropriate is set by a control disable flag (stp) of 1 bit. Note that bat1sts is a 4-bit code indicating the state of the 1st power storage device 310, and bat2sts is a 4-bit code indicating the state of the 2 nd power storage device 320.
Fig. 5 shows the setting contents indicated by the respective bits in the decision criterion 210. Specifically, the bits b0 to b2 are bits indicating the state of the 1st power storage device 310, and indicate whether or not the 1st power storage device 310 is in a standby state (including a non-chargeable/dischargeable state), a charged state, and a discharged state. bit b3 is a spare bit for the 1st power storage device 310. Similarly, the bits b4 to b6 are bits indicating the state bat2sts of the 2 nd power storage device 320, and indicate whether or not the 2 nd power storage device 320 is in a standby state (including a non-chargeable/dischargeable state), a charged state, and a discharged state. The b7 bit is a spare bit for the 2 nd power storage device 320. Since the bits b8 to b14 are not used in the decision reference 210, they are not shown in fig. 4 and 5.
The contents of the setting of the determination criterion 210 shown in fig. 4 will be specifically described below. In the 1st combination (row 1), the decision reference 210 sets the b0 bit and the b4 bit to "1" and sets all the other bits to "0". Therefore, the 1st combination (row 1) corresponds to a combination in which both the 1st power storage device 310 and the 2 nd power storage device 320 are in the standby state. On the other hand, in the 6 th combination (row 6), the decision criterion 210 sets the b1 bit and the b6 bit to "1" and sets all the other bits to "0". Therefore, the 6 th combination (row 6) corresponds to a combination in which the 1st power storage device 310 is in the charged state and the 2 nd power storage device 320 is in the discharged state.
Bit b15 in decision reference 210 indicates a control disable flag (stp). The combination of rows set to "0" in the control prohibition flag is an appropriate combination that does not require prohibition of control, and the combination of rows set to "1" in the control prohibition flag is an inappropriate combination that should prohibit control.
For example, setting the control prohibition flag to "0" in the 1st combination (row 1) of the determination criterion 210 indicates that a combination in which both the 1st electric storage device 310 and the 2 nd electric storage device 320 are in the standby state is not prohibited. On the other hand, setting the control prohibition flag to "1" in the 6 th combination (row 6) of determination criterion 210 indicates a combination in which the 1st electric storage device 310 is prohibited from being in the charged state and the 2 nd electric storage device 320 is prohibited from being in the discharged state.
In the determination criterion 210, the control prohibition flags for the 6 th combination (row 6) and the 8 th combination (row 8) are set to "1", and the control prohibition flags for the other combinations are set to "0". That is, determination criterion 210 prohibits a combination in which one of 1st power storage device 310 and 2 nd power storage device 320 is in a discharged state and the other is in a charged state. This is because, when the two power storage devices 310 and 320 are simultaneously charged and discharged, only the power is transferred from one power storage device to the other power storage device, and power is lost wastefully if power loss or the like at the time of power transmission is taken into consideration. Therefore, the determination criterion 210 prohibits such a combination of the states in which charge and discharge coexist.
For example, fig. 6 shows an example of a setting screen of the determination criterion 210, and the control device 100 displays a matrix-like setting screen of 3 × 3 shown in fig. 6 on the touch panel 16, for example.
In the setting screen shown in fig. 6, two combinations in which one of the 1st power storage device 310 and the 2 nd power storage device 320 is in a charged state and the other is in a discharged state are displayed with black circles indicating prohibition, whereas combinations other than these two combinations are displayed with white circles indicating non-prohibition, in such a current setting situation, for example, when the user wants to prohibit a combination in which both the 1st power storage device 310 and the 2 nd power storage device 320 are in a charged state again, the setting can be changed by touching the cell (cell) at the center in the matrix of 3 × 3 with a finger or the like.
Next, instrument management processing executed by the control device 100 according to embodiment 1 will be described with reference to flowcharts shown in fig. 7, 8, 9, and 12. The CPU11 starts the instrument management processing shown in fig. 7, for example, in response to the power being turned on.
Upon starting the instrument management processing, the CPU11 selects one instrument from among the instruments connected to the control device 100 (step S11). Then, the CPU11 functions as the state acquisition unit 101 to acquire the current state of the selected instrument (step S12).
The devices connected to the control device 100 are devices managed by the control device 100 provided in the HEMS1000, such as the electrical device 400, the 1st power storage device 310, the 2 nd power storage device 320, and the power generation device 500. The current state of the instrument refers to an operation state, a standby state, and the like. For example, if the selected device is the 1st power storage device 310 or the 2 nd power storage device 320, the CPU11 acquires information on whether or not the device is in any one of a charging state, a discharging state, and a standby state. The CPU11 selects one of the devices connected to the control device 100, and transmits a status acquisition inquiry to the selected device via the in-home network 710 and the in-home interface 17. Then, a response to the inquiry is received from the device of the transmission destination, and information indicating the current state of the device is acquired.
When the state of the selected device is acquired, the CPU11 functions as the request acquisition unit 102 to acquire the control request flag (step S13). Then, it is determined whether or not there is a control request to any of the connected devices, based on the acquired control request flag (step S14).
The control request flag is a flag set for each instrument controllable by the control device 100. When a user operates an arbitrary instrument or issues a control request according to a predetermined operation schedule, a control request flag of the instrument to be controlled (operation target) is set. On the other hand, the control request flag is cleared for an instrument having no control request. The CPU11 determines whether or not there is a control request for any instrument based on whether or not the control request flag corresponding to each instrument connected is set.
If there is no control request (step S14; n), the CPU11 next determines whether there is an information acquisition error (step S15). That is, the CPU11 determines whether or not the state of the selected device is normally acquired.
If no information acquisition error occurs in step S15 (step S15; n), the CPU11 updates the instrument management data 200 based on the acquired information (step S16). That is, when the current state of the selected device changes from the previously acquired state, the CPU11 rewrites the information indicating the previous state stored as the device management data 200 into the information indicating the current state. Then, the process proceeds to step S20.
On the other hand, if there is an information acquisition error (step S15; y), the CPU11 attempts to acquire the information again. Specifically, the CPU11 determines whether or not the value of the variable i indicating the number of retries of state acquisition exceeds a predetermined upper limit (step S17). The value of the variable i is set to 0 in the initial state.
If the number of retries does not exceed the upper limit number (step S17; n), such as when a retry is not performed at one time, the CPU11 increments the value of a variable i indicating the number of retries (step S18), and returns the instrument management processing to step S12. That is, the state of the selected device is tried to be acquired again, and whether or not the acquisition is normal is determined.
If the state cannot be acquired from the selected device even if the upper limit number of retries is reached, that is, if the number of retries exceeds the upper limit number in step S17 (step S17; y), the CPU11 stops the retries of acquiring the state of the selected device and initializes the value of a variable i indicating the number of retries to 0 (step S19). Then, since the CPU11 cannot acquire the state of the selected instrument, the instrument management data 200 is not updated, and the instrument management process proceeds to step S20.
In step S20, the CPU11 functions as the request acquisition unit 102 again. That is, the CPU11 acquires the control request flag (step S20), and determines whether or not there is a control request to any of the connected devices based on the acquired control request flag (step S21). The processing of steps S20, S21 is the same as the processing of steps S13, S14. Thus, the CPU11 constantly monitors whether or not a control request for any instrument is issued while acquiring the state from the selected instrument.
In the case where there is no control demand (step S21; n), next the CPU11 determines whether all the connected instruments have been selected (step S22).
In the case where not all the connected instruments have been selected (step S22; n), the CPU11 selects one unselected instrument among the connected instruments (step S23), and returns the instrument management processing to step S12. That is, the CPU11 executes the processing of the above-described steps S12 to S21 with respect to the newly selected instrument. In this way, the CPU11 repeats the process of acquiring the status and updating the instrument management data 200 for all the instruments connected.
Finally, when all the connected instruments have been selected (step S22; y), the instrument management process performed by the control device 100 is transferred to the flowchart shown in fig. 8.
In the flowchart shown in fig. 8, when all the connected instruments have been selected, the CPU11 executes restriction information generation processing in accordance with the acquired current state of each instrument (step S24). The limitation information is information indicating control to be limited with respect to a combination of current states of the two power storage devices 310 and 320. For example, the 2 nd power storage device 320 should not be shifted to the charged state when the 1st power storage device 310 is in the discharged state, and the 1st power storage device 310 should not be shifted to the charged state when the 2 nd power storage device 320 is in the discharged state. The restriction information indicates the following control: since the combination of the states of the two power storage devices 310 and 320 is shifted from the current combination to the prohibited combination in this way, the combination should be limited. The restriction information generation process will be described in detail with reference to a flowchart shown in fig. 9.
In the flowchart shown in fig. 9, when the limitation information generation process is started, the CPU11 functions as the state acquisition unit 101, acquires the current state of the 1st power storage device 310 from the information indicating the states of the respective devices stored as the device management data 200 (step S101), and then acquires the current state of the 2 nd power storage device 320 (step S102).
Then, the CPU11 initializes the restriction information of the 1st power storage device 310 and the restriction information of the 2 nd power storage device 320 (step S103). Specifically, the CPU11 initializes both the value of bat1continf of the 4-bit code indicating the restriction information of the 1st power storage device 310 and the value of bat2continf of the 4-bit code indicating the restriction information of the 2 nd power storage device 320 to "0000".
When the restriction information is initialized, the CPU11 refers to the determination criterion 210, and generates restriction information on the 2 nd power storage device 320 with respect to the current state of the 1st power storage device 310 (step S104).
Specifically, fig. 10 shows an example of generating restriction information of the 2 nd power storage device 320 with respect to the current state of the 1st power storage device 310. The CPU11 compares the value of bat1sts, which is a code indicating the current state of the 1st power storage device 310 obtained, with the bits b0 to b3 for the state of the 1st power storage device 310 in the criterion 210 in order from the 1st combination (line 1) of the criterion 210. Then, the state of the 2 nd power storage device 320 to be restricted with respect to the current state of the 1st power storage device 310 is determined with reference to the control prohibition flag (stp) of the line that matches the current state of the 1st power storage device 310.
For example, as shown in fig. 10, when the 1st electric storage device 310 is in a discharged state, the value "0100" of bat1sts, which is a code indicating the current state of the 1st electric storage device 310, matches the bits of b0 through b3 in the 7 th through 9 th combinations (lines 7 through 9 surrounded by broken lines) of the determination criterion 210. The control prohibition flag (stp) for the 8 th combination (line 8) of the 7 th to 9 th combinations is set to "1" as enclosed by a broken line. Therefore, in the case where the 1st power storage device 310 is in the discharged state, the state of charge of the 2 nd power storage device 320 is restricted. In this case, the value of bat2 continif, which is a code indicating the restriction information of the 2 nd power storage device 320, is changed from the initialized value "0000" to the value of bat2sts, which is a code indicating the state of the 2 nd power storage device 320 of the 8 th combination (row 8), which is "0010". Thus, when the 1st power storage device 310 is in the discharged state, the state of charge of the 2 nd power storage device 320 is set to be limited in the limitation information of the 2 nd power storage device 320.
When there are a plurality of states of the 2 nd power storage device 320 to be restricted with respect to the value of bat1sts which is a code indicating the current state of the 1st power storage device 310, bat2continf which is a code indicating restriction information of the 2 nd power storage device 320 is generated by taking OR ("OR") which is the value of bat2sts which is a code indicating a plurality of states of the 2 nd power storage device 320 to be restricted. This makes it possible to set a plurality of states to be limited as the limitation information of the 2 nd power storage device 320. For example, when 1st power storage device 310 is in the charged state, when both the charged state (bat2sts ═ 0010 ") and the discharged state (bat2sts ═ 0100") of 2 nd power storage device 320 are restricted, the value of bat2 continif, which is a code indicating restriction information of 2 nd power storage device 320, is set to a value "0110" obtained by taking an OR of "0010" and "0100". This enables a plurality of states to be restricted.
When the restriction information of the 2 nd power storage device 320 is generated, the CPU11 refers to the determination criterion 210, and generates the restriction information of the 1st power storage device 310 with respect to the current state of the 2 nd power storage device 320 (step S105).
That is, similarly to step S104 in which the restriction information of the 2 nd power storage device 320 is generated, the CPU11 compares, in order from the 1st combination (line 1) of the criterion 210, the obtained bat2sts, which is a code indicating the current state of the 2 nd power storage device 320, and the bits b4 to b7 for the state of the 2 nd power storage device 320 in the criterion 210. Then, the control prohibition flag (stp) of the line matching the value of bat2sts, which is a code indicating the current state of the 2 nd power storage device 320, is referred to, and a code indicating restriction information of the 1st power storage device 310, which specifies the state of the 1st power storage device 310 to be restricted with respect to the current state of the 2 nd power storage device 320, that is, bat1 continnf, is generated.
For example, as shown in fig. 10, when the 2 nd power storage device 320 is in the standby state, the value "0001" of bat1sts, which is a code indicating the current state of the 2 nd power storage device 320, matches the settings of the 1st combination (line 1), the 4 th combination (line 4), and the 7 th combination (line 7) in the criterion 210. In these combinations (row 1, row 4, and row 7), the control prohibition flag (stp) is set to "0", and therefore, when the 2 nd power storage device 320 is in the standby state, there is no state of the 1st power storage device 310 to be restricted. In this case, bat1 continue, which is a code indicating the restriction information of the 1st power storage device 310, remains "0000" without being changed.
When the restriction information of the 1st power storage device 310 and the restriction information of the 2 nd power storage device 320 are generated in this way, the CPU11 ends the restriction information generation process shown in fig. 9. When the restriction information generation processing is ended, the instrument management processing executed by the control device 100 returns to the processing of the flowchart shown in fig. 8.
When the restriction information generation process is ended in step S24, the CPU11 functions as the restriction information reporting unit 108. That is, the CPU11 reports the current states of the two 1st electric storage devices 310, 320 and the generated restriction information (step S25). Specifically, the CPU11 reports the current states of the two 1st power storage devices 310 and 320 and the generated restriction information to the user by displaying them on the touch panel 16 or a user interface on the device side operated by the user (hereinafter referred to as the touch panel 16).
Fig. 11 shows a specific display example. As shown in fig. 11, the CPU11 displays information indicating the current states (any one of the standby state, the charging state, and the discharging state) of the 1st power storage device 310 and the 2 nd power storage device 320 and the state in which the current states are to be restricted on the touch panel 16 or the like. Specifically, in the example of fig. 11, since the 1st power storage device 310 is in the current discharge state, the CPU11 reports to the user, as the restriction information, information that the 2 nd power storage device 320 should not be shifted to the charge state. On the other hand, since the 2 nd power storage device 320 is in the current standby state, the CPU11 reports to the user that there is no control of the 1st power storage device 310 that should be restricted. In this way, the CPU11 reports restriction information indicating that inappropriate control should not be performed with respect to the current state of the electric storage device to the user.
After that, the CPU11 updates the instrument management data 200 (step S26), returning the instrument management processing to step S11. That is, the CPU11 then repeats the following processing: the state of each connected device is acquired, and restriction information is generated and displayed based on the newly acquired state.
On the other hand, when there is a control request for any instrument while the state of each instrument is acquired as described above, that is, when there is a control request in step S14 in the flowchart shown in fig. 7 (step S14; yes) or when there is a control request in step S21 (step S21; yes), the instrument management process executed by the control device 100 proceeds to step S27 in the flowchart shown in fig. 8.
When there is a control request (steps S14, S21; y), the CPU11 determines whether the acquired control request is a control request for the power storage device (step S27). As a result of the determination, if the acquired control request is not the control request for the power storage device (step S27; n), the CPU11 controls the device to be controlled in accordance with the acquired control request (step S28).
On the other hand, if the acquired control request is a control request for the power storage device (step S27; y), the CPU11 executes a power storage device control process in accordance with the acquired control request (step S29). This power storage device control process will be described in detail with reference to a flowchart shown in fig. 12.
In the flowchart shown in fig. 12, when the power storage device control process is started, the CPU11 acquires control information from the acquired control request (step S201). The control information is, for example, ID (Identification) information indicating the electric storage device to be controlled out of the 1st electric storage device 310 and the 2 nd electric storage device 320, and information indicating the control content such as whether to perform charging or discharging or to shift to a standby state.
When acquiring the control information, the CPU11 functions as the state acquisition unit 101 to acquire the states of the two power storage devices 310 and 320 when the power storage device to be controlled is controlled in accordance with the acquired control request (step S202). Specifically, when the CPU11 requests the control of one of the two power storage devices 310 and 320, it acquires the state after the control of the power storage device to be controlled, which is determined based on the acquisition result of the control information, and acquires the current state of the power storage device not to be controlled, out of the two power storage devices 310 and 320, from the information indicating the states of the respective instruments, which is acquired by the state acquisition unit 101 and stored as the instrument management data 200.
On the other hand, when a request for control of both the two power storage devices 310 and 320 is simultaneously obtained, both the two power storage devices 310 and 320 are power storage devices to be controlled, and there is no power storage device that is not to be controlled. Therefore, the CPU11 obtains the states of the two power storage devices 310 and 320 after the control in accordance with the control request, based on only the control contents for both of the two power storage devices 310 and 320 determined in accordance with the control request obtained by the request obtaining unit 102, without using the state already obtained by the state obtaining unit 101.
When the states of the two power storage devices 310 and 320 are acquired, the CPU11 sets a state determination code (step S203). Thus, a combination is constructed in which the states of the two power storage devices 310 and 320 are combined when the power storage device to be controlled is controlled in accordance with the control request. The state determination code is an 8-bit code representing a combination obtained by combining the controlled states of the two power storage devices 310 and 320 when the power storage device to be controlled is controlled in accordance with the control request. In the state determination code, the 0 th bit to the 3 rd bit represent the state of the 1st electric storage device 310, and the 4 th bit to the 7 th bit represent the state of the 2 nd electric storage device 320.
For example, when a control request for shifting the 1st power storage device 310 to the discharge state is received when the 2 nd power storage device 320 is in the standby state, the CPU11 sets the 0 th bit to the 3 rd bit of the state determination code to "0100" indicating the discharge state of the 1st power storage device 310, and sets the 4 th bit to the 7 th bit of the state determination code to "0001" indicating the standby state of the 2 nd power storage device 320. As a result, as shown in fig. 13, 8-bit state determination codes with b0 bits to b7 bits set to "00010100" are generated.
When the state determination code is set, the CPU11 functions as the determination unit 103, refers to the determination criterion 210, and determines whether or not the combination of the states of the two power storage devices 310 and 320 in the case where the power storage device to be controlled is controlled in accordance with the acquired control request matches the prohibited combination (step S204).
Specifically, the CPU11 compares the set state determination code with the b0 bits to b7 bits indicating the states of the two power storage devices 310 and 320 in the determination criterion 210 in order from the 1st combination (line 1) of the determination criterion 210. Then, the control disable flag (stp) of the line in which the state decision code coincides with the b0 bits to b7 bits of the decision criterion 210 is referred to. As a result of the reference, the CPU11 determines that the combination of the states of the two power storage devices 310 and 320 does not match the prohibited inappropriate combination when the control prohibition flag is set to "0", and determines that the combination of the states of the two power storage devices 310 and 320 matches the prohibited inappropriate combination when the control prohibition flag is set to "1".
For example, as shown in fig. 13, when the state determination code is set to "00010100", the state determination code matches the 7 th combination (line 7) in the determination criterion 210. Since the control prohibition flag in the 7 th combination is set to "0", the CPU11 determines that the combination of the states of the two power storage devices 310 and 320 does not become the prohibited combination even if the control in accordance with the control request is executed.
As a result of the determination, if it is determined that the combination of the states of the two power storage devices 310 and 320 does not become the prohibited combination even if the power storage device to be controlled is controlled in accordance with the acquired control request (step S205; n), the CPU11 functions as the power storage device control unit 105 and controls the power storage device to be controlled in accordance with the acquired control request (step S206).
On the other hand, as a result of the determination, if it is determined that the combination of the states of the two power storage devices 310 and 320 is the prohibited combination when the power storage device to be controlled is controlled in accordance with the acquired control request (step S205; "yes"), the CPU11 functions as the warning notification unit 104 and notifies a warning indicating that the control based on the acquired control request is inappropriate (step S207). As shown in fig. 14, for example, the CPU11 sets "a combination of the states of two power storage devices at the time of executing an input operation to a prohibited combination. "such a warning message is displayed on the touch screen 16. In addition, the CPU11 can also report a warning by emitting an alarm sound. Alternatively, the CPU11 may transmit information indicating a warning to an instrument operated by the user, and the alarm may be reported by a screen display, an alarm sound, or the like in the instrument operated by the user.
At this time, the CPU11 confirms whether or not to execute control, although it is inappropriate control (step S208). For example, as shown in fig. 14, the CPU11 associates "yes" and "no" operation panels with "even if do they execute? "such confirmation messages are displayed together on the touch screen 16. In response to this confirmation, the user can input a request for re-control to execute control despite improper control by touching the operation panel of "yes" displayed on the touch panel 16. On the other hand, when the user touches the operation panel of "no", the no more control request is not input. The CPU11 functions as the request acquisition unit 102, waits for such an operation from the user, and determines whether or not a request for re-control is accepted (step S209).
When the request for the re-control is accepted (yes in step S209), the CPU11 determines that a predetermined condition for releasing the restriction is satisfied, and reports the fact that the exceptional control is executed by displaying the fact on the touch panel 16, for example (step S210). Then, the CPU11 functions as the power storage device control unit 105 to control the power storage device to be controlled in accordance with the acquired control request without limiting the combination of the states of the two power storage devices 310 and 320 to the prohibited combination (step S206). That is, when the request acquisition unit 102 acquires the regenerative control request, the CPU11 does not make a determination by the determination unit 103, or when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the prohibited combination regardless of whether the power storage device to be controlled is controlled in accordance with the regenerative control request, functions as the power storage device control unit 105, and controls the power storage device to be controlled in accordance with the regenerative control request. Then, the power storage device control process shown in fig. 12 is ended.
On the other hand, if no request for the re-control is accepted (step S209; n), the CPU11 reports to the user that the cooperation condition indicating that the cooperation of the two power storage devices 310 and 320 is not appropriate is erroneously displayed on the touch panel 16 or the like (step S211). Then, the CPU11 ends the power storage device control process shown in fig. 12 without executing control in accordance with the acquired control request. When the power storage device control processing is ended, the equipment management processing executed by the control device 100 returns to the processing of the flowchart shown in fig. 8.
When an instrument other than the power storage device is controlled in step S27 or when the 1st power storage device 310 and the 2 nd power storage device 320 are cooperatively controlled in step S29, the CPU11 acquires the state of the controlled instrument (step S30) and determines whether the control result is normal (step S31). That is, the CPU11 checks whether or not the device to be controlled can be controlled in accordance with the acquired control request.
In the case where the control result is normal (step S31; y), the CPU11 causes the instrument management processing to shift to step S24. That is, the CPU11 newly generates restriction information reflecting the state of the controlled device, and displays the restriction information on the touch panel 16 or the like together with the state of the controlled device.
If the control result is not normal (step S31; n), the CPU11 reports an error indicating that the error is present to the user by displaying the error on the touch panel 16 or the like (step S32). Then, the CPU11 returns the instrument management processing to step S11 after having the instrument management processing shifted to step S26 to update the instrument management data 200. That is, the CPU11 then repeats the following processing: the state of each connected instrument is acquired and each instrument is controlled according to the control requirement.
As described above, the control device 100 according to embodiment 1 controls the two power storage devices 310 and 320 so that the combination of the states of the two power storage devices 310 and 320 does not become a prohibited combination in accordance with the determination criterion 210 stored in the storage unit 150. On the other hand, the power storage device can be controlled by a selection operation by the user without referring to the determination criterion 210.
As a result, for example, improper control between the two power storage devices 310 and 320, such as the other discharging while one is charging, can be prevented, and the user can intentionally perform control different from normal control. That is, it is possible to realize flexible control such as transferring electric power from the power storage device in the electric vehicle 300 to the stationary power storage device or performing the reverse process thereof in an emergency or the like.
(embodiment mode 2)
Next, embodiment 2 of the present invention will be explained.
In embodiment 1 described above, one determination criterion 210 is stored in the storage unit, and the two power storage devices 310 and 320 are controlled in accordance with two schemes, i.e., whether or not the one determination criterion is satisfied. In contrast, the control device according to embodiment 2 holds a plurality of determination criteria having different settings in the storage unit, and controls the two power storage devices 310 and 320 in accordance with the determination criteria selected from the plurality of determination criteria according to the situation. The following description is made.
The function of the control device according to embodiment 2 will be described with reference to fig. 15. The same structure as that in embodiment 1 will be omitted as appropriate. The control device 110 according to embodiment 2 functionally includes a state acquisition unit 101, a request acquisition unit 102, a determination unit 103, a warning notification unit 104, a power storage device control unit 105, a restriction information generation unit 107, a restriction information notification unit 108, and a schedule management unit 109. The functions of these respective sections are realized by the CPU11, ROM12, RAM13, and the like in cooperation. The control device 110 further includes a storage unit 151. The storage section 151 is realized by the function of the flash memory 14 or the like.
The storage unit 151 stores the instrument management data 200, the 1st criterion 211, the 2 nd criterion 212, and the 3 rd criterion 213. The instrument management data 200 is data for the control device 110 to manage each instrument provided in the HEMS1000, and stores information indicating the state of each instrument. Determination criterion 1, determination criterion 2, and determination criterion 3 213 are determination criteria for which whether or not appropriate or inappropriate, that is, whether or not the combination is to be prohibited is set for each combination of the state of power storage device 1 310 and the state of power storage device 2 320, that is, the setting of whether or not the combination is to be prohibited is different from each other.
Fig. 16A, 16B, and 16C show examples of the 1st criterion 211, the 2 nd criterion 212, and the 3 rd criterion 213, respectively. Each criterion is set for 9 combinations of the state (bat1sts) of the 1st power storage device 310 and the state (bat2sts) of the 2 nd power storage device 320 from the 1st combination (line 1) to the 9 th combination (line 9) in the same manner as the criterion 210 in embodiment 1. In addition, whether each of the 9 combinations is appropriate or inappropriate is set with a 1-bit control disable flag (stp). The setting contents indicated by the bits in the respective determination criteria are the same as those shown in fig. 5.
The 1st criterion 211 shown in fig. 16A is the criterion with the largest restriction among the three criteria 211, 212, and 213 used in the normal state (default state). The setting content of the 1st criterion 211 is the same as the criterion 210 in embodiment 1. That is, determination criterion 1 211 prohibits a combination in which one of 1st power storage device 310 and 2 nd power storage device 320 is in a discharged state and the other is in a charged state.
The 2 nd criterion 212 shown in fig. 16B is a criterion used when the predetermined 1st condition is satisfied. This 1st condition is satisfied when a selection operation of the 2 nd determination criterion 212 is accepted from a user who desires not to prohibit a part of combinations prohibited in the 1st determination criterion 211.
Specifically, although the combination in which the 1st power storage device 310 is in the charged state and the 2 nd power storage device 320 is in the discharged state is prohibited in the 6 th combination (row 6) with respect to the 2 nd determination criterion 212, the combination in which the 1st power storage device 310 is in the discharged state and the 2 nd power storage device 320 is in the charged state is not prohibited in the 8 th combination (row 8) unlike the 1st determination criterion 211.
That is, determination criterion 2 212 does not prohibit the movement of electric power from stationary type 1st power storage device 310 to 2 nd power storage device 320 in electric vehicle 300. This is because, at first glance, it is not useful to move electric power from one of the two electric storage devices 310 and 320 to the other, but it is not appropriate to move electric power from the stationary-type battery 312 to the battery 322 in the electric vehicle 300, depending on the situation, because it is also considered that the user desires to quickly charge the electric vehicle 300.
The 3 rd criterion 213 shown in fig. 16C is a criterion used when the predetermined 2 nd condition is satisfied. The 2 nd condition is satisfied when a predetermined condition is satisfied, such as an emergency time, e.g., when a power failure occurs or when emergency information is received.
Specifically, the 3 rd decision criterion 213 sets all the b 15-bit control prohibition flags to "0". That is, the 3 rd determination criterion 213 is set such that all combinations are appropriate combinations and all combinations for the two power storage devices 310 and 320 are permitted.
In this way, in the 2 nd decision criterion 212 and the 3 rd decision criterion 213, one or more combinations prohibited from being inappropriate in the 1st decision criterion 211 are set as appropriate, and therefore, there is a setting of relaxing the restriction. The determination unit 103 selects an optimum determination criterion from the three determination criteria 211, 212, and 213 according to whether or not the 1st or 2 nd condition that should relax the restriction is satisfied, and determines whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination with reference to the selected determination criterion. When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the combination prohibited in the selected determination criterion, the power storage device control unit 105 does not control the power storage device to be controlled, and when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the combination prohibited in the selected determination criterion, controls the power storage device to be controlled as required.
Specifically, when neither the 1st condition nor the 2 nd condition is satisfied, the determination unit 103 refers to the 1st determination criterion 211. That is, the determination unit 103 determines whether or not the combination of the states of the two power storage devices 310 and 320 in the case where the power storage device to be controlled is controlled in accordance with the request for control acquired by the request acquisition unit 102 matches the combination prohibited in the 1st determination criterion 211. When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the combination prohibited in the 1st determination criterion 211, the power storage device control unit 105 does not control the power storage device to be controlled, and when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the combination prohibited in the 1st determination criterion 211, the power storage device control unit controls the power storage device to be controlled as required.
On the other hand, when the 1st condition that should relax the restriction is satisfied, the determination unit 103 refers to the 2 nd determination criterion 212. That is, the determination unit 103 determines whether or not the combination of the states of the two power storage devices 310 and 320 in the case where the power storage device to be controlled is controlled in accordance with the request matches the combination prohibited in the 2 nd determination criterion 212. Therefore, even if the combination of the states of the two power storage devices 310 and 320 matches some of the combinations prohibited by the 1st determination criterion 211, the power storage device control unit 105 controls the power storage device to be controlled as required.
When the 2 nd condition that should relax the restriction is satisfied, the determination unit 103 refers to the 3 rd determination criterion 213. That is, the determination unit 103 determines whether or not the combination of the states of the two power storage devices 310 and 320 in the case of controlling the power storage device to be controlled in accordance with the request matches the combination prohibited in the 3 rd determination criterion 213. Therefore, the electric storage device control unit 105 controls the electric storage device to be controlled as required, regardless of which of the plurality of combinations prohibited in the 1st determination criterion 211 the combination of the states of the two electric storage devices 310 and 320 matches.
Next, the power storage device control process executed by the control device 110 according to embodiment 2 will be described with reference to a flowchart shown in fig. 17. Note that the instrument management processing and the constraint information generation processing executed by the control device 110 according to embodiment 2 are the same as the processing executed by the control device 100 according to embodiment 1 shown in the flowcharts of fig. 7, 8, and 9, and therefore, the description thereof is omitted.
When the power storage device control process is started, the CPU11 acquires control information from the acquired control request (step S301). The CPU11 functions as the state acquisition unit 101, and acquires the states of the two power storage devices 310 and 320 when the power storage device to be controlled is controlled in accordance with the acquired control request (step S302). That is, the CPU11 acquires the controlled state of the power storage device to be controlled, which is determined based on the acquisition result of the control information, and acquires the current state of the power storage device not to be controlled, out of the two power storage devices 310 and 320, from the information indicating the states of the respective devices stored as the device management data 200.
After acquiring the states of the two power storage devices 310 and 320, the CPU11 sets a state determination code (step S303). The processing of steps S301 to S303 is the same as that in embodiment 1.
After setting the state determination code, the CPU11 selects a reference criterion from the three criteria 211, 212, and 213 stored in the storage unit 151. Specifically, it is determined whether or not there is an instruction to select the CPU11 or the 2 nd criterion 212 (step S304). That is, the CPU11 determines whether or not a selection instruction of the 2 nd determination criterion 212 is accepted from the user as the 1st condition that the restriction should be relaxed. The user can input an instruction to select the 2 nd determination criterion 212 at an appropriate timing, for example, via the touch panel 16. As a result of the determination, if it is determined that the 2 nd criterion 212 is selected (step S304; y), the CPU11 selects the 2 nd criterion 212 as the reference criterion (step S305).
On the other hand, if it is determined that the 2 nd criterion 212 is not selected (step S304; n), the CPU11 next determines whether the situation is an emergency situation (step S306). That is, as the 2 nd condition that the restriction should be relaxed, the CPU11 determines whether or not a predetermined condition such as an emergency is satisfied. For example, CPU11 determines that it is an emergency when the supply of electric power from commercial power supply 600 is stopped, when emergency information is received, or the like.
As a result of the determination, if it is determined that the vehicle is in an emergency (step S306; y), the CPU11 selects the 3 rd criterion 213 as the reference criterion (step S307). On the other hand, if it is determined that the emergency is not present (step S306; n), the CPU11 selects the 1st criterion 211 as the reference criterion (step S308).
When any of the 1st determination criterion 211, the 2 nd determination criterion 212, or the 3 rd determination criterion 213 is selected, the CPU11 functions as the determination unit 103, and determines whether or not the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination when the power storage device to be controlled is controlled in accordance with the acquired control request, with reference to the selected determination criterion (step S309).
As a result of the determination, when the CPU11 functions as the power storage device control unit 105 and determines that the states of the two power storage devices 310 and 320 do not become the prohibited combination even if the power storage device to be controlled is controlled in accordance with the acquired control request (step S310; n), the CPU11 controls the power storage device to be controlled in accordance with the acquired control request (step S311).
On the other hand, if it is determined that the states of the two power storage devices 310 and 320 are in the prohibited combination if the power storage device to be controlled is controlled in accordance with the acquired control request (yes in step S310), the CPU11 functions as the warning notification unit 104, and notifies the user of a cooperation condition indicating that the cooperation of the two power storage devices 310 and 320 is not appropriate by mistake on the touch panel 16 or the like (step S312). In this way, when the power storage device to be controlled is controlled in accordance with the acquired control request or when the cooperation condition error is reported without executing the control in accordance with the acquired control request, the CPU11 ends the power storage device control process shown in fig. 17.
As described above, the control device 110 according to embodiment 2 holds the three determination criteria 211, 212, and 213, and normally controls the two power storage devices 310 and 320 so that the combination of the states of the two power storage devices 310 and 320 does not become a prohibited combination in accordance with the 1st determination criterion 211. On the other hand, in an emergency such as when a selection operation is performed by the user or when disaster information is received, the two power storage devices 310 and 320 are controlled in accordance with the 2 nd determination criterion 212 or the 3 rd determination criterion 213, which are different from the 1st determination criterion 211, in prohibited combinations.
As a result, for example, improper control between the two power storage devices 310 and 320, such as the other being discharged during charging, can be prevented, and the combination of prohibition can be changed according to the situation, so that the two power storage devices 310 and 320 can be flexibly controlled. That is, while embodiment 1 provides completely unlimited control without complying with the determination criterion 210, embodiment 2 can set the necessary limit as the determination criterion even in exceptional situations, and therefore can control both the power storage devices 310 and 320 with high reliability.
In embodiment 2, the determination unit 103 selects a reference criterion from the three criteria 211, 212, and 213 stored in the storage unit 151 in advance according to whether or not the predetermined 1st condition or 2 nd condition is satisfied, and determines whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination when the power storage device to be controlled is controlled in accordance with the control request acquired by the request acquisition unit 102 with reference to the selected criterion. However, as a modification of embodiment 2, the determination unit 103 may refer to the 1st determination criterion 211 at the time point when the request acquisition unit 102 acquires the request for control, determine whether or not the combination of the states of the two power storage devices 310 and 320 in the case where the power storage device to be controlled is controlled in accordance with the request is the combination prohibited in the 1st determination criterion 211, and when it is determined that the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination, sequentially refer to the 2 nd determination criterion 212 and the 3 rd determination criterion 213 when the 1st condition and the 2 nd condition determined in advance are satisfied, and determine whether or not the combination of the states of the two power storage devices 310 and 320 in the case where the power storage device to be controlled in accordance with the request is the prohibited combination.
A modification of embodiment 2 will be specifically described. When control of any of the two power storage devices 310 and 320 is requested, the determination unit 103 first determines whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination when the power storage device to be controlled is controlled in accordance with the request, with reference to the 1st determination criterion 211. When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the combination prohibited in the 1st determination criterion 211, the power storage device control unit 105 controls the power storage device to be controlled as required. On the other hand, when determination unit 103 determines that the combination of the states of both power storage devices 310 and 320 matches the combination prohibited in determination criterion 1 211, warning notification unit 104 notifies the user of a warning by displaying a warning screen shown in fig. 14 on touch panel 16, for example. In addition, the warning report section 104 confirms whether or not to execute control, although it is inappropriate control.
When the request acquisition unit 102 does not receive a request for the control from the user as a response to such a warning, it is determined that the predetermined condition is not satisfied, and the power storage device control unit 105 does not control the power storage device to be controlled. On the other hand, when the request acquisition unit 102 receives a request for the re-control from the user, the determination unit 103 determines that the predetermined condition is satisfied. In this case, the determination unit 103 refers to the 2 nd determination criterion 212, and determines whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination when the power storage device to be controlled is controlled in accordance with the request for the re-control. When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the combination prohibited in the 2 nd determination criterion 212, the power storage device control unit 105 controls the power storage device to be controlled as required. On the other hand, when determination unit 103 determines that the combination of the states of both power storage devices 310 and 320 matches the combination prohibited in determination criterion 2 212, warning notification unit 104 again displays a warning screen shown in fig. 14 on touch panel 16, for example, to notify the user of the warning.
When the request acquisition unit 102 does not receive a request for further re-control from the user as a response to such a warning, the power storage device control unit 105 determines that the predetermined condition 2 is not satisfied and does not control the power storage device to be controlled. On the other hand, when the request acquisition unit 102 receives a request for the re-control from the user, the determination unit 103 determines that the predetermined condition 2 is satisfied. In this case, the determination unit 103 further refers to the 3 rd determination criterion 213, and determines whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination when the power storage device to be controlled is controlled in accordance with the request for the re-control. When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the combination prohibited in the 3 rd determination criterion 213, the power storage device control unit 105 controls the power storage device to be controlled as required. As described above, since the 3 rd determination criterion 213 does not prohibit all combinations of the states of the two power storage devices 310 and 320, the power storage device control unit 105 controls the power storage device to be controlled in accordance with the request for any control request.
In this way, each time a request for control is received from the user, the determination unit 103 sequentially selects a determination criterion for reducing the number of prohibited combinations, and determines whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination when the power storage device to be controlled is controlled in accordance with the request. In embodiment 1, when a request for a re-control is received from a user, all controls are not prohibited and the power storage device to be controlled is controlled, whereas in the modification of embodiment 2, a criterion for gradually relaxing the restriction is referred to. As a result, the two power storage devices 310 and 320 can be controlled in cooperation with each other more flexibly according to the situation.
(embodiment mode 3)
Next, embodiment 3 of the present invention will be explained.
In embodiments 1 and 2 described above, the control devices 100 and 110 determine whether or not the combination of the states of the two power storage devices 310 and 320 is a prohibited combination, and control the plurality of power storage devices in accordance with the determination result. In contrast, the control device according to embodiment 3 controls the two power storage devices 310 and 320 with reference to not only the states of the two power storage devices 310 and 320 but also the power generation state of the power generation device 500. The following description is made.
Referring to fig. 18, the functions of the control device according to embodiment 3 will be described. Note that the same configurations as those in embodiment 1 or 2 will be omitted as appropriate. The control device 120 according to embodiment 3 functionally includes a state acquisition unit 101, a request acquisition unit 102, a determination unit 103, a warning report unit 104, a power storage device control unit 105, a schedule management unit 109, a power generation information acquisition unit 121, and a fee information acquisition unit 122. The functions of these respective sections are realized by the CPU11, ROM12, RAM13, and the like in cooperation. The control device 120 includes a storage unit 152. The storage section 152 is realized by the function of the flash memory 14 or the like. Further, the control device 120 is also provided with the restriction information generating unit 107 and the restriction information reporting unit 108, as in embodiments 1 and 2, but is not shown in fig. 18 for ease of understanding.
The power generation information acquisition unit 121 acquires power generation information of the power generation facility 500. The power generation information includes the current state of the power generation equipment 500 and power generation prediction information in the power generation equipment 500, as described later. Specifically, the power generation information acquisition unit 121 acquires, as power generation information, information as to whether or not it is estimated that power generation by the power generation facility 500 is achieved by a threshold amount or more, that is, whether or not the power is sufficiently supplied by the amount of power generated based on sunlight.
The fee information acquiring unit 122 acquires the electricity fee information. The electricity charge information is information on electricity selling price and electricity purchasing price based on electricity as described later. Specifically, the charge information acquiring unit 122 acquires, as the electricity charge information, information as to whether the electricity selling price is higher than the electricity purchasing price by a threshold price or more, that is, whether the profit is larger when electricity is sold to a power company or the like than when the storage battery is charged.
The determination unit 103 determines whether or not a combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information acquired by the power generation information acquisition unit 121, and the electricity rate information acquired by the rate information acquisition unit 122 matches a prohibited combination when the power storage device to be controlled is controlled in accordance with the request acquired by the request acquisition unit 102. Specifically, the determination unit 103 refers to the 1st criterion 221 or the 2 nd criterion 222 stored in the storage unit 152 and executes the determination process.
The storage unit 152 stores the instrument management data 200, the 1st criterion 221, and the 2 nd criterion 222. The instrument management data 200 is data for the control device 120 to manage each instrument provided in the HEMS1000, and stores information indicating the state of each instrument. The 1st determination criterion 221 and the 2 nd determination criterion 222 are determination criteria in which whether appropriate or inappropriate, that is, whether or not the combination to be prohibited is set for each combination of the state of the 1st power storage device 310, the state of the 2 nd power storage device 320, the power generation state of the power generation device 500, and the like, is different from each other. The power generation state and the like include power generation information and power rate information of the power generation facility 500 described later. The power generation information of the power generation facility 500 includes the current power generation state of the power generation facility 500 described later and power generation prediction information.
Fig. 19A and 19B show examples of the 1st criterion 221 and the 2 nd criterion 222, respectively. For easy understanding, only the combination in which inhibition is described (that is, the control inhibition flag (stp) is set to "1") and the combination in which inhibition is not described in the 1st determination criterion 221 shown in fig. 19A and the 2 nd determination criterion 222 shown in fig. 19B.
Fig. 20 shows the setting contents indicated by each bit in the 1st criterion 221 and the 2 nd criterion 222. The setting contents indicated by the bits b0 to b7 are the same as those in embodiments 1 and 2. That is, the bits b0 to b7 indicate whether the 1st power storage device 310 or the 2 nd power storage device 320 is in any state of a standby state (including a non-chargeable and dischargeable state), a charged state, and a discharged state.
The bits b8 to b11 are bits indicating which of the 1st power storage device 310 and the 2 nd power storage device 320 should be maintained in a state with priority. When the b8 bit is set to "1", it indicates that the state of the 1st power storage device 310 is maintained preferentially, and when the b9 bit is set to "1", it indicates that the state of the 2 nd power storage device 320 is maintained preferentially. Since the B10 bits and the B11 bits are spare bits and are not used in embodiment 3, they are not shown in fig. 19A and 19B.
The b12 bits through b14 bits are bits for indicating the power generation state of the power generation device 500 and the like (pvsts). Specifically, the b12 bit indicates whether or not the power generation is expected to be equal to or more than a threshold amount. bit b13 indicates whether or not the electricity generation is a situation in which the price of the electricity selling unit is higher than the price of the electricity purchasing unit by a threshold price or more and the threshold amount or more is estimated. The b14 bit is a spare bit for the power generating equipment 500. Further, pvsts is a 3-bit code indicating the power generation state and the like of the power generation device 500 among b12 bits to b14 bits. Note that the b15 bit indicates a control prohibition flag in the same manner as in embodiments 1 and 2.
The contents of the setting of the 1st criterion 221 shown in fig. 19A and the 2 nd criterion 222 shown in fig. 19B will be specifically described below.
The 1st criterion 221 shown in fig. 19A is a criterion used in a normal state (default state). In the 1st decision reference 221, the b1 bit and the b6 bit are set to "1" in the 1st combination (row 1), and the b2 bit and the b5 bit are set to "1" in the 2 nd combination (row 2). That is, in the 1st determination criterion 221, a combination in which one of the two power storage devices 310 and 320 is in a charged state and the other is in a discharged state is prohibited. In addition, in the 1st decision criterion 221, the b1 bit and the b5 bit are set to "1" in the 3 rd combination (row 3). That is, in the 1st determination criterion 221, a combination of the states of charge of both the power storage devices 310 and 320 is prohibited.
In addition, in the 1st decision criterion 221, in the 4 th to 6 th combinations (the 4 th to 6 th lines), bat1sts and bat2sts, which are codes indicating the states of the two power storage devices 310 and 320, are set in the same manner as in the 1st to 3 rd combinations (the 1st to 3 rd lines), and the b12 bit is set to "1". That is, in the 1st determination criterion 221, even in a situation where it is estimated that the power generation by the power generation device 500 is achieved by the threshold amount or more, a combination in which one of the two power storage devices 310, 320 is in a charged state and the other is in a discharged state, and a combination in which both the two power storage devices 310, 320 are in a charged state are prohibited.
Also, in the 1st decision reference 221, the b1 bit and the b5 bit are set to "1" and the b13 bit is set to "1" in the 7 th combination (row 7). That is, in the 1st decision criterion 221, in a situation where the price of electricity sold is higher than the price of electricity purchased by a threshold price or more and electricity generation is expected to be performed by a threshold amount or more, a combination of the states of charge of both the power storage devices 310 and 320 is prohibited. This is because, when the electricity selling price is relatively high, it is more economically efficient to sell the generated electricity to a power company or the like than to charge the electricity generated by the electricity generation facility 500 to the electricity storage facility.
The 2 nd criterion 222 shown in fig. 19B is a criterion used when a predetermined condition that should relax the restriction is satisfied. This condition is satisfied when the electricity purchase price exceeds a predetermined reference price, that is, when the electricity charge increases due to, for example, a distribution law of demand response.
In the 2 nd decision reference 222, the b1 bit and the b5 bit are set to "1" and the b9 bit is set to "1" in the 1st combination (row 1). That is, the 2 nd determination criterion 222 is set to: the combination of the two power storage devices 310, 320 in the charged state is prohibited, and the 2 nd power storage device 320 is preferentially charged when both the power storage devices 310, 320 are in the charged state.
The 2 nd and 3 rd combinations (rows 2 and 3) of the 2 nd criterion 222 are the same as the 2 nd and 5 th combinations (rows 2 and 5) of the 1st criterion 221, respectively. That is, in the 2 nd determination criterion 222, the combination in which the 2 nd power storage device 320 is in the charged state while the 1st power storage device 310 is in the discharged state is prohibited regardless of the power generation condition.
On the other hand, the 2 nd determination criterion 222 does not prohibit the combination in which the 2 nd electric storage device 320 is in the discharged state while the 1st electric storage device 310 is in the charged state, which is prohibited in the 1st and 4 th combinations (1 st and 4 th rows) of the 1st determination criterion. This is because, at first glance, it does not seem useful to transfer electric power from one of the two power storage devices 310, 320 to the other, but when the electric power rate increases, it is more economically preferable to transfer the electric power stored in the 2 nd power storage device 320 in the electric vehicle 300 to the fixed 1st power storage device 310 and use it as electric power for use in the house.
In addition, the 2 nd determination criterion 222 is a combination in which the 1st power storage device 310 and the 2 nd power storage device 320 are both in the charged state in a situation where power generation by the threshold amount or more is not predicted to be prohibited in the 6 th and 7 th combinations (rows 6 and 7) of the 1st determination criterion.
In this way, the 2 nd determination criterion 222 has a setting in which the restriction is relaxed compared to the 1st determination criterion 221. The determination unit 103 selects an optimum criterion from the two criteria 221 and 222 according to whether or not the condition for relaxing the restriction is satisfied, and determines whether or not a combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information is a prohibited combination with reference to the selected criterion. When the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the combination prohibited in the selected determination criterion, the power storage device control unit 105 does not control the power storage device to be controlled, and when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the combination prohibited in the selected determination criterion, controls the power storage device to be controlled as required.
Next, power storage device control processing executed by the control device 120 according to embodiment 3 will be described with reference to a flowchart shown in fig. 21. Note that the instrument management processing and the constraint information generation processing executed by the control device 120 according to embodiment 3 are the same as the processing executed by the control device 100 according to embodiment 1 shown in the flowcharts of fig. 7, 8, and 9, and therefore, the description thereof is omitted.
When the power storage device control process is started, the CPU11 acquires control information from the acquired control request (step S401). The CPU11 functions as the state acquisition unit 101, and acquires the states of the two power storage devices 310 and 320 when the power storage device to be controlled is controlled in accordance with the acquired control request (step S402). That is, the CPU11 acquires the state after control of the power storage device to be controlled, which is determined based on the acquisition result of the control information, and acquires the current state of the power storage device not to be controlled, out of the two power storage devices 310 and 320, from the information indicating the state of each device stored as the device management data 200.
After acquiring the states of the two power storage devices 310 and 320, the CPU11 sets a state determination code (step S403). The processing in steps S401 to S403 is the same as that in embodiments 1 and 2.
After the state determination code is set, the CPU11 executes the power generation information acquisition process (step S404). That is, the CPU11 controls the two power storage devices 310 and 320 based on not only the states of the two power storage devices 310 and 320 but also the power generation state of the power generation device 500 and the like, and therefore obtains necessary information in step S404. The power generation information acquisition process will be described in detail with reference to a flowchart shown in fig. 22.
In the flowchart shown in fig. 22, when the power generation information acquisition process is started, the CPU11 functions as the power generation information acquisition unit 121 to acquire the current state of the power generation equipment 500 (step S501). The current state of the power generating equipment 500 refers to information on whether the power generating equipment 500 is currently generating power, information on the amount of power generated when generating power, and the like. The CPU11 transmits an inquiry about state acquisition to the power generation facility 500 via the in-house network 710 and the in-house interface 17. Then, by receiving a response to the inquiry from the power generation facility 500, information indicating the current state of the power generation facility 500 is acquired.
Next, the CPU11 acquires the power generation prediction information in the power generation facility 500 (step S502). The power generation prediction information is information of the power generation state of the power generation facility 500 in a predetermined period in the future. For example, when it is late at night, the CPU11 acquires the power generation prediction information that the power generation equipment 500 will not be able to generate power. In addition, even in the daytime, since the amount of solar radiation depends on the weather and the season, the CPU11 accesses the cloud server 800 as needed to acquire weather forecast information, calendar information, and the like, and acquires power generation prediction information.
After acquiring the current power generation state and the power generation prediction information, the CPU11 functions as the fee information acquisition unit 122 to acquire the electricity fee information (step S503). The electricity charge information is specifically information of the selling price and purchasing price of electricity. Since the electricity selling price and the electricity purchasing price vary depending on the state of the time zone or the like, the CPU11 acquires information on the electricity selling price and the electricity purchasing price at the present time and during the predicted electricity generation period. The electric power rate information is stored in the storage unit 152 in advance, for example, and the CPU11 acquires the electric power rate information from the storage unit 152. Alternatively, the CPU11 can access the cloud server 800 as necessary to acquire the electricity fee information.
After acquiring the current power generation state, the power generation prediction information, and the electricity rate information, the CPU11 sets a code (pvsts) indicating the power generation state and the like based on the acquired information (step S504). Specifically, when the amount of power generation estimated from the power generation prediction information is not equal to or greater than the threshold amount, the CPU11 sets the b12 bit of the code indicating the power generation state or the like to "0" and sets the b13 bit to "0". On the other hand, when the power generation amount estimated from the power generation prediction information is equal to or greater than the threshold amount, the CPU11 compares the electricity selling price and the electricity purchasing price. As a result of the comparison, the CPU11 sets the b12 bit of the code indicating the power generation state or the like to "0" and the b13 bit to "1" when the electricity selling price is higher than the electricity purchasing price by the threshold price or more, and sets the b12 bit of the code indicating the power generation state or the like to "1" and the b13 bit to "0" when the electricity selling price is not higher than the electricity purchasing price by the threshold price or more.
After setting the code indicating the power generation state or the like, the power generation information acquisition process shown in the flowchart of fig. 22 is ended, and the power storage device control process executed by the control device 120 returns to the flowchart shown in fig. 21.
In fig. 21, when executing the power generation information acquisition process, the CPU11 selects a criterion to be referred to from the two criteria 221 and 222 stored in the storage unit 152. Specifically, the CPU11 determines whether the electricity purchase price exceeds the reference price based on the acquired electricity rate information (step S405). When the purchase price does not exceed the reference price (step S405; n), the CPU11 selects the 1st criterion 221 as the reference criterion (step S406). On the other hand, if the purchase price exceeds the reference price (step S405; yes), the CPU11 selects the 2 nd criterion 222 as the reference criterion (step S407).
When the 1st criterion 221 or the 2 nd criterion 222 is selected, the CPU11 functions as the determination unit 103, and determines whether or not a combination obtained by combining the states of the two power storage devices 310 and 320, the power generation state, and the like in the case where the power storage device to be controlled is controlled in accordance with the acquired control request matches a prohibited combination, with reference to the selected criterion (step S408).
As a result of the determination, when it is determined that the combination obtained by combining the states of the two power storage devices 310 and 320, the power generation state, and the like does not become the prohibited combination even if the power storage device to be controlled is controlled in accordance with the acquired control request (step S409; n), the CPU11 functions as the power storage device control unit 105 to control the power storage device to be controlled in accordance with the acquired control request (step S410).
On the other hand, as a result of the determination, if it is determined that the combination obtained by combining the states of the two power storage devices 310 and 320 and the power generation state is the prohibited combination if the power storage device to be controlled is controlled in accordance with the acquired control request (step S409; y), the CPU11 functions as the warning notification unit 104, and notifies the user of the incorrect cooperation condition indicating that the cooperation of the two power storage devices 310 and 320 is not appropriate by erroneously displaying the cooperation condition on the touch panel 16 or the like (step S411). In this way, when the power storage device to be controlled is controlled in accordance with the acquired control request or when the cooperation condition error is reported without executing the control in accordance with the acquired control request, the CPU11 ends the power storage device control process shown in fig. 21.
As described above, the control device 120 according to embodiment 3 holds the 1st determination criterion 221 and the 2 nd determination criterion 222 in which the combination that refers not only to the states of the two power storage devices 310 and 320 but also to the power generation state of the power generation device 500 is set as a prohibited combination, and controls the two power storage devices 310 and 320 so that the combination of the states of the two power storage devices 310 and 320 does not become a prohibited combination in accordance with any determination criterion.
As a result, when the electricity selling price is high, electricity can be sold in priority to charging, or when the electricity rate is high, the plurality of power storage devices can be controlled under a condition that is considered to be optimal in terms of time, including the information on the power generation and the information on the electricity rate, such as when the electricity rate is transferred from the 2 nd power storage device 320 provided in the electric vehicle 300 to the 1st power storage device 310.
In embodiment 3, the determination unit 103 selects a reference criterion from the two criteria 221 and 222 stored in the storage unit 152 in advance, based on whether or not a predetermined condition relating to the electricity rate is satisfied, and determines whether or not a combination obtained by combining the states of the two electricity storage devices 310 and 320, the power generation information, and the electricity rate information is a prohibited combination when the electricity storage device to be controlled is controlled in accordance with the request for control acquired by the request acquisition unit 102, with reference to the selected criterion. However, as a modification of embodiment 3, the determination unit 103 may refer to the 1st determination criterion 221 at the time point when the request acquisition unit 102 acquires the request for control, determine whether or not a combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information in the case where the power storage device to be controlled is controlled in accordance with the request is a combination prohibited in the 1st determination criterion 221, and if it is determined that the combination matches the prohibited combination, may not control the power storage device to be controlled if a predetermined condition is not satisfied, and may control the power storage device to be controlled in accordance with the request if the predetermined condition is satisfied.
A modification of embodiment 3 will be specifically described. When control of any of the two power storage devices 310 and 320 is requested, the determination unit 103 first determines whether or not a combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information is a prohibited combination in the case where the power storage device to be controlled is controlled in accordance with the request, with reference to the 1st determination criterion 221. When the determination unit 103 determines that the combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information does not match the combination prohibited in the 1st determination criterion 221, the power storage device control unit 105 controls the power storage device to be controlled as required. On the other hand, when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information matches the combination prohibited in the 1st determination criterion 221, the warning notification unit 104 notifies the user of a warning by displaying a warning screen shown in fig. 14 on the touch panel 16, for example. Then, the warning report section 104 confirms whether or not to execute control, although it is inappropriate control.
When the request acquisition unit 102 does not receive a request for the control from the user as a response to such a warning, the electric storage device control unit 105 determines that the predetermined condition is not satisfied and does not control the electric storage device to be controlled. On the other hand, when the request acquisition unit 102 receives a request for the re-control from the user, the electric storage device control unit 105 determines that the predetermined condition is satisfied, and controls the electric storage device to be controlled in accordance with the received request for the re-control. This prevents inappropriate control between the two power storage devices 310 and 320 while referring to the power generation information and the electricity rate information, and enables execution of even inappropriate control in an emergency or the like, thereby enabling flexible control.
Alternatively, when a request for a re-control is received from the user as a response to the warning issued by the warning notifying unit 104, the determining unit 103 may execute the determining process with reference to the 2 nd determination criterion 222. Referring to the result of the 2 nd determination criterion 222, when the determination unit 103 determines that the combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information does not match the combination prohibited in the 2 nd determination criterion 222, the power storage device control unit 105 controls the power storage device to be controlled as required. On the other hand, when the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information matches the combination prohibited in the 2 nd determination criterion 222, the power storage device control unit 105 does not control the power storage device to be controlled. In this way, when a request for a re-control from a user is received, the determination process is executed with reference to the criterion for relaxing the restriction, and therefore the cooperative control of the two power storage devices 310 and 320 can be performed more flexibly.
(embodiment mode 4)
Next, embodiment 4 of the present invention will be explained.
In embodiments 1, 2, and 3 described above, the control devices 100, 110, and 120 are connected to the two power storage devices 310 and 320 via the in-home network 710, and can freely exchange information with the two power storage devices 310 and 320, thereby acquiring the states of the two power storage devices 310 and 320. However, in embodiment 4, the following case will be explained: the HEMS includes an electric storage device that is not connected to the control device via a network and cannot be controlled by the control device.
Fig. 23 shows the structure of the HEMS in embodiment 4. The HEMS1001 includes a control device 130 for controlling the entire system, an electric apparatus 400, a power generation facility 500, a power meter 620, and a converter 630. The HEMS1001 includes the 1st power storage device 310 and the 2 nd power storage device 330. Note that the same configurations as those in embodiments 1, 2, and 3 will be omitted as appropriate.
The 1st power storage device 310 and the 2 nd power storage device 330 are devices that store electric power supplied from the commercial power supply 600 and electric power generated by the power generation device 500. The electric power stored in each power storage device is supplied to the electric equipment 400 or is sold to an electric power company via the commercial power supply 600. The 1st power storage device 310 is a power storage device that controls a stationary storage battery. The 2 nd power storage device 330 is a power storage device for a vehicle that controls a battery mounted on an electric vehicle.
1st power storage device 310 and control device 130 are connected via in-home network 710. That is, the 1st power storage device 310 is a power storage device that can be controlled by the control device 130 and that has the same configuration as the 1st power storage device 310 in embodiments 1, 2, and 3. On the other hand, unlike the 2 nd power storage device 320 in embodiments 1, 2, and 3, the 2 nd power storage device 330 is not connected to the control device 130 via the in-house network 710. That is, the control device 130 cannot exchange information with the 2 nd power storage device 330, and cannot control the 2 nd power storage device 330. Therefore, the control device 130 cannot directly acquire information on which state of the standby state, the charged state, and the discharged state of the 2 nd power storage device 330 is currently in from the 2 nd power storage device 330. Therefore, in embodiment 4, the control device 130 indirectly acquires the state of the 2 nd power storage device 330 using the converter 630. Note that the configuration of the 2 nd power storage device 330 other than the interface 327 for communicating with the control device 130 is the same as that of the 2 nd power storage device 320 in embodiments 1, 2, and 3.
The converter 630 is mounted at a position closer to the 2 nd power storage device 330 than a connection point of the power line from the 1st power storage device 310, of the power line connected between the 2 nd power storage device 330 and the distribution board 600. Thus, the power meter 620 can measure the electric power input to the 2 nd power storage device 330 or the electric power output from the 2 nd power storage device 330.
The state acquisition unit 101 acquires the state of the 2 nd power storage device 330 that cannot be controlled by the control device 130, based on the measurement result of the converter 630. Then, the determination unit 103 determines whether or not a combination of the states of the two power storage devices 310 and 330 including the state of the 2 nd power storage device 330 that cannot be controlled by the control device 130 is inappropriate when the power storage device to be controlled is controlled in accordance with the control request acquired by the request acquisition unit 102.
Specifically, when the power value measured by the converter 630 is a value close to 0 within a predetermined error range, the state acquisition unit 101 determines that the 2 nd power storage device 330 is in a standby state in which it is neither charged nor discharged, and acquires the state of the 2 nd power storage device 330. Further, the state acquisition unit 101 determines that the 2 nd power storage device 330 is in the charged state when the power value measured by the converter 630 is a positive value larger than 0 by an error range or more, and determines that the 2 nd power storage device 330 is in the standby state and acquires the state of the 2 nd power storage device 330 when the power value measured by the converter 630 is a negative value smaller than 0 by an error range or more. The relationship between the positive and negative values of the power value measured by the converter 630 and whether the 2 nd power storage device 330 is in the charged state or the discharged state may be reversed.
As described above, the control device 130 according to embodiment 4 obtains the state by measuring the electric power transmitted by the power line from the power storage device that cannot be controlled by the control device 130. The processing other than the state acquisition of the 2 nd power storage device 330 is the same as that of embodiments 1, 2, and 3 described above, and therefore, the description thereof is omitted here.
As a result, even when an uncontrollable power storage device is included, the two power storage devices 310 and 330 can be controlled so that the combination of the states of the two power storage devices 310 and 330 does not become a prohibited combination. In addition, it is possible to realize flexible control such as transferring electric power from the power storage device in the electric vehicle 300 to the stationary power storage device or performing the reverse process thereof in an emergency or the like.
In embodiment 4, the control device 130 can control the 1st power storage device 310 that controls a stationary battery among the two power storage devices 310 and 330 provided in the HEMS1001, and cannot control the 2 nd power storage device 330 that controls a battery mounted on an electric vehicle. However, control device 130 may be capable of controlling the power storage device for the vehicle, while it may not be capable of controlling the stationary power storage device. In this case, the state acquisition unit 101 acquires the state of the uncontrollable stationary-type power storage device via the converter 630 that measures the electric power transmitted through the power line connected to the uncontrollable stationary-type power storage device. Further, control device 130 executes control so that a combination of the states of the two power storage devices including the acquired state of the uncontrollable power storage device does not become a prohibited combination.
(modification example)
While the embodiments of the present invention have been described above, the present invention can be modified and applied in various ways.
In the present invention, which part of the configuration, function, and operation described in the embodiment is adopted is arbitrary. In the present invention, other structures, functions, and operations than those described above may be employed.
In the above embodiment, the control devices 100, 110, 120, and 130 control the two power storage devices so that the combination of the states of the two power storage devices does not become a combination including prohibition of both the charged state and the discharged state. However, the control device according to the present invention may execute the same processing not only for two power storage devices but also for three or more power storage devices. That is, the control device according to the present invention may control the three or more power storage devices such that the combination of the states of the three or more power storage devices does not become a combination including both prohibition of the charged state and the discharged state when the power storage device to be controlled is controlled in accordance with the request, and the control device may control the three or more power storage devices such that the combination of the states of the three or more power storage devices does not become one or more prohibition combinations depending on the situation.
In the above embodiment, the 1st power storage device 310 is a stationary power storage device, and the 2 nd power storage devices 320 and 330 are vehicle power storage devices that control the battery 322 provided in the electric vehicle 300. However, in the present invention, each of the plurality of power storage devices may be a stationary power storage device or a vehicle power storage device. That is, the control device according to the present invention may control a plurality of power storage devices all of which are stationary power storage devices, or may control a plurality of power storage devices all of which are vehicle power storage devices.
In addition, the setting of the combination prohibited in the determination criterion 210 and the like may be appropriately changed. That is, the combination of the states of the plurality of power storage devices can be freely changed depending on the usage environment of the power storage devices, which combination is an appropriate combination that should not be prohibited, and which combination is an inappropriate combination that should be prohibited. The number of determination criteria held by the control device is not limited to one to three as in the above-described embodiment, but may be four or more.
For example, in the above-described embodiment 3 and the modification of embodiment 3, the control device 120 acquires both the power generation information and the electricity rate information, and determines whether or not a combination obtained by combining the states of the two power storage devices 310 and 320, the power generation information, and the electricity rate information in the case of controlling the power storage device to be controlled matches a prohibited combination with reference to the 1st determination criterion 221 or the 2 nd determination criterion 222. However, the control device according to the present invention may acquire only the power generation information of the power generation information and the power rate information, determine whether or not a combination obtained by combining the states of the two power storage devices 310 and 320 and the power generation information in the case of controlling the power storage device to be controlled matches a prohibited combination, and execute the above-described processing based on the determination result. Alternatively, the control device according to the present invention may acquire only the electricity rate information out of the power generation information and the electricity rate information, determine whether or not a combination obtained by combining the states of the two power storage devices 310 and 320 and the electricity rate information in the case of controlling the power storage device to be controlled matches a prohibited combination, and execute the above-described processing based on the determination result.
In addition, it may be set so that a predetermined condition that the restriction should be released or relaxed is satisfied when the conditions other than the case where the user requests the re-control, the case where the user performs the selection operation, the case where the emergency case occurs, and the case where the electricity rate is increased, as exemplified in the above embodiment.
In the above embodiment, the determination unit 103 determines whether or not the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination by setting the state determination code indicating the combination of the state of the power storage device to be controlled in the case of control in accordance with the control request and the current state of the power storage device not to be controlled, and comparing the set state determination code with the determination criterion stored in the storage units 150, 151, and 152. However, in the present invention, the determination unit 103 may determine whether or not the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination by comparing the state of the power storage device to be controlled when the power storage device is controlled in accordance with the control request and the state to be restricted of the power storage device to be controlled indicated by the restriction information generated by the restriction information generation unit 107.
For example, when the power storage device to be controlled is the 1st power storage device 310, the determination unit 103 refers to the code bat1 continue indicating the restriction information of the 1st power storage device 310 generated in advance, and determines whether or not the state after the control of the 1st power storage device 310 matches the state to be restricted indicated by bat1 continue. For example, when the restriction information indicates that the control for shifting the 1st power storage device 310 to the discharge state should be restricted, and the control for shifting the 1st power storage device 310 to the discharge state is required, the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 matches the prohibited combination, and when the control for shifting the 1st power storage device 310 to a state other than the discharge state is required, the determination unit 103 determines that the combination of the states of the two power storage devices 310 and 320 does not match the prohibited combination. Although the restriction information needs to be generated before the control of the power storage device is requested, when the control of the power storage device is requested, the state of the power storage device to be controlled after the control may be compared with the restriction information once. That is, it is not necessary to sequentially compare the combination of the states of the two power storage devices 310 and 320 with the combination set in the determination criterion, and therefore, the processing when the control is requested can be simplified.
In the above embodiment, the control devices 100, 110, 120, and 130 include the touch panel 16 functioning as a user interface. However, the control device according to the present invention may not include a user interface (input device or output device) such as the touch panel 16. When the control device does not have a user interface, the control device cannot execute, for example, a report by the warning report unit 104 and the restriction information report unit 108. Therefore, the control device according to the present invention may not include the warning notification unit 104 or the restriction information notification unit 108. Alternatively, the control device according to the present invention may be configured to correspond to the warning notification unit 104 or the restriction information notification unit 108, and may include: report information is transmitted to another device (for example, a device currently operated by a user) connected to the control apparatus, and inappropriate control, restriction information, a current state of each device, and the like are reported via an output device provided in the other device.
The personal computer or the like can also function as the control devices 100, 110, 120, and 130 according to the present invention by applying an operation program that defines the operation of the control devices 100, 110, 120, and 130 according to the present invention to an existing personal computer or information terminal device.
Such a program may be distributed by any method, and may be stored in a computer-readable recording medium such as a CD-ROM (compact disc Read-Only Memory), a DVD (Digital Versatile disc), an MO (Magneto Optical disc), or a Memory card, or may be distributed via a communication network such as the internet.
The present invention is capable of various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above embodiments are illustrative of the present invention, and do not limit the scope of the present invention. That is, the scope of the present invention is not the embodiments but is shown by the claims. Various modifications made within the scope of the claims and within the meaning of the equivalent invention are considered to be within the scope of the present invention.
