The operation plan selection screen 650 includes an area 651, an area 652, and a button 653.

The area 651 is an area where an outline of the selected operation plan is presented by a character string or an image. Therefore, the user can grasp the outline of the currently selected operation plan by referring to the information displayed in the area 651. FIG. 7 shows an example in which an outline of the minimum power purchase plan that is the currently selected operation plan is presented in the area 651.

The area 652 is an area in which a radio button for receiving a selection of an operation plan is displayed. This radio button presents driving plan candidates that can be selected by the user, and accepts selection of the driving plan by the user. This radio button sets the operation plan displayed in the area clicked by the user as the selected operation plan.

The button 653 is a button for accepting an instruction to confirm the selected operation plan as the operation plan to be adopted. That is, when the button 653 is pressed by the user, the operation plan selected by the radio button displayed in the area 652 is determined as the operation plan to be adopted.

Next, the user-defined plan editing screen will be described with reference to FIG. Screen 660 is a screen (user-defined plan edit screen) for allowing the user to edit the user-defined plan. The power mode setting device 300 can communicate with the terminal device 600 via the in-home network 810 or the out-of-home network 820 and display the screen 660 on the terminal device 600. Then, the power mode setting device 300 can acquire the information received from the screen 660 (for example, information specifying the power mode and the start time) from the terminal device 600. The screen 660 includes an area 661, an area 662, and a button 663.

The area 661 is an area where an outline of the user-defined plan being edited is presented by a character string or an image. Therefore, the user can grasp the outline of the user-defined plan being edited by referring to the information displayed in the area 661.

The area 662 is an area in which a set of a drop-down list that accepts selection of a power mode and a drop-down list that accepts selection of a start time for setting the power mode is displayed. The drop-down list that accepts the selection of the power mode displays the power mode that is being selected, displays the power mode candidates that can be selected when clicked, and the power displayed in the clicked area when clicked. Set the mode candidate to the selected power mode. The drop-down list that accepts the selection of the start time displays the start time being selected, displays a selectable start time candidate when clicked, and the start displayed in the clicked area when clicked Set the time candidate to the selected start time.

The button 663 is a button for accepting an instruction to confirm a plan defined by a combination of a selected power mode and a selected start time as a user-defined plan to be adopted. That is, when the button 663 is pressed by the user, the plan defined by the combination of the power mode and the start time selected from the drop-down list displayed in the area 662 is determined as the operation plan to be adopted. .

Next, a method in which the power mode setting device 300 sets the power mode in the power control device 100 will be described with reference to FIG.

First of all, the plan stop is set as the operation plan until 06:00. Therefore, the power mode is not set from the power mode setting device 300 to the power control device 100 until 06:00.

Here, it is assumed that the operation plan (minimum power purchase plan) is registered by the user at 06:00. Then, the power mode setting device 300 starts processing for setting the power mode in the power control device 100 periodically according to the registered operation plan. Specifically, the power mode setting device 300 first sets the EV charging mode in the power control device 100 at 06:00. Then, the power mode setting device 300 sets the EV charging mode in the power control device 100 every 10 minutes from 06:00 to 07:00. Further, the power mode setting device 300 sets the minimum power purchase mode in the power control device 100 every 10 minutes from 07:00 to 08:00.

Here, it is assumed that the operation plan (plan stop) is registered by the user at 08:00. Then, the power mode setting device 300 ends the process of setting the power mode in the power control device 100 after 08:00.

Next, a power mode setting process executed by the power mode setting device 300 according to the first embodiment will be described with reference to the flowchart shown in FIG. The power mode setting device 300 starts the power mode setting process shown in FIG. 10 in response to the power being turned on.

First, the CPU 31 executes an initialization process (step S101). For example, the CPU 31 sets the operation plan to plan stop or stops the setting timer. Note that the setting timer is a timer that is started when a schedule is set and is restarted at a predetermined cycle (for example, 10 minutes) until the schedule is released thereafter. That is, the setting timer is a timer indicating the timing for setting the power mode, and is a timer that is restarted every time the power mode is set. The setting timer is composed of, for example, the RTC 35.

CPU31 will complete | finish the process of step S101, and will discriminate | determine whether there exists an instruction | indication of a driving plan change (step S102). For example, the CPU 31 determines whether the change instruction information transmitted from the terminal device 600 has been received by the home interface 36 or the home interface 37. The change instruction information is information indicating an operation plan, for example. Here, in response to the fact that the user has received an operation plan change instruction from the touch screen 68, the terminal device 600 sends the change instruction information to the power mode setting device 300 via the home interface 66 or the home interface 67. Send.

Hereinafter, the reception of information from the terminal device 600 by the CPU 31 via the in-home interface 36 or the out-of-home interface 37 is simply referred to as the CPU 31 receiving information from the terminal device 600. Similarly, when the CPU 31 transmits information to the terminal device 600 via the in-home interface 36 or the outside interface 37, the CPU 31 simply transmits information to the terminal device 600. Further, the reception of information from the power control apparatus 100 by the CPU 31 via the in-home interface 36 or the external interface 37 is simply referred to as the CPU 31 receiving information from the power control apparatus 100. Similarly, when the CPU 31 transmits information to the power control apparatus 100 via the in-home interface 36 or the outside interface 37, the CPU 31 simply transmits information to the power control apparatus 100.

When the CPU 31 determines that there is an operation plan change instruction (step S102: YES), the CPU 31 accepts an operation plan designation (step S103). For example, the CPU 31 transmits the information by plan stored in the flash memory 34 to the terminal device 600, displays the screen 650 on the terminal device 600, and causes the terminal device 600 to accept the designation of the operation plan. On the other hand, the terminal device 600 transmits the operation plan information to the power mode setting device 300. Then, the CPU 31 acquires the driving plan information received from the terminal device 600.

In addition, when a user-defined plan is designated by the user, the CPU 31 further displays information on the details of the user-defined plan on the terminal device 600 (hereinafter referred to as “user-defined plan information” as appropriate). .) Is accepted. Here, the terminal device 600 transmits user-defined plan information to the power mode setting device 300. Then, the CPU 31 acquires user-defined plan information received from the terminal device 600. The CPU 31 stores operation plan information and user-defined plan information in the flash memory 34. Note that the user-defined plan information may be included in the plan-specific information.

CPU31 will determine whether an operation plan is a plan stop, if the process of step S103 is completed (step S104). When the CPU 31 determines that the operation plan is a plan stop (step S104: YES), the CPU 31 cancels the schedule (step S105). Note that canceling the schedule is to end the periodic setting process of the power mode.

CPU31 will stop the timer for a setting, if the process of step S105 is completed (step S106). As described above, the setting timer is a timer that counts the cycle for setting the power mode. Accordingly, when the schedule is canceled and the schedule is no longer being set, the CPU 31 stops the setting timer.

On the other hand, when determining that the operation plan is not a plan stop (step S104: NO), the CPU 31 sets a schedule (step S107). Specifically, the CPU 31 sets the schedule associated with the operation plan designated by the user as the schedule to be adopted based on the plan-specific information stored in the flash memory 34.

CPU31 will set power mode, if the process of step S107 is completed (step S108). Specifically, the CPU 31 identifies a power mode to be set at the current time based on the set schedule, and information indicating the identified power mode (hereinafter referred to as “power mode information”) to the power control apparatus 100. Send. On the other hand, the power control apparatus 100 stores the power mode information received from the power mode setting apparatus 300 in the storage unit 150. Thereafter, the power control apparatus 100 executes the power control process in the power mode indicated by the power mode information stored in the storage unit 150.

CPU31 will start the timer for a setting, if the process of step S108 is completed (step S109). When determining that there is no operation plan change instruction (step S102: NO), the CPU 31 determines whether or not the schedule is being set when the process of step S106 or step S109 is completed (step S110).

CPU31 will discriminate | determine whether the value of the timer for a setting is more than predetermined value, if it determines with the schedule being set (step S110: YES) (step S111). This predetermined value is a value determined in advance according to a cycle for setting the power mode (hereinafter referred to as “setting cycle” as appropriate). In other words, the setting timer takes a set period from the time when it is cleared to the predetermined value.

When the CPU 31 determines that the value of the setting timer is equal to or greater than the predetermined value (step S111: YES), the CPU 31 sets the power mode (step S112). Specifically, the CPU 31 transmits power mode information to the power control apparatus 100. Thus, CPU31 sets the power mode which should be set shown by the set schedule to the power control apparatus 100 for every setting period.

CPU31 will restart the timer for a setting, if the process of step S112 is completed (step S113). That is, the CPU 31 clears the setting timer value. The CPU 31 determines that the schedule is not being set (step S110: NO), determines that the setting timer value is not equal to or greater than the predetermined value (step S111: NO), or completes the process of step S113. The process returns to step S102.

In the present embodiment, the power mode is set in the power control apparatus 100 based on the schedule indicating the power mode set in the power control apparatus 100 and the period in which the power control apparatus 100 sets the power mode. Therefore, according to the present embodiment, it is possible to reduce time and effort for the user to set the power mode in the power control apparatus 100.

In the present embodiment, among the schedules indicated by the plan-specific information, the schedule associated with the operation plan indicated by the information acquired as the determination information is determined as the schedule to be adopted. Therefore, according to the present embodiment, it is possible to further reduce the effort for the user to set the power mode in the power control apparatus 100.

In the present embodiment, determination information indicating the power mode set in the power control apparatus 100 and the period for setting the power mode is acquired based on the operation received from the user. Therefore, according to the present embodiment, the power mode can be set in the power control apparatus 100 based on the schedule desired by the user, and convenience is improved.

In the present embodiment, the power mode is set in the power control apparatus 100 periodically based on the determined schedule. Therefore, according to the present embodiment, a power mode is not correctly set in the power control apparatus 100 due to a communication error or the like, or an unexpected power mode is set in the power control apparatus 100 by another apparatus or the like. Even so, the power mode according to the schedule can be reliably set in the power control apparatus 100.

(Embodiment 2)
In the first embodiment, an example in which the power mode is set in the power control apparatus 100 according to the schedule associated with the operation plan selected from the operation plans prepared in advance or the schedule associated with the user-defined plan. explained. In the present invention, the schedule that is referred to when setting the power mode in the power control apparatus 100 is not limited to this example. Hereinafter, an example in which a schedule to be referred to is set based on information registered in the system by the calendar function of the home controller will be described.

Hereinafter, fundamentally, a description will be given of the difference between the power control system 1000 according to the second embodiment and the power control system 1000 according to the first embodiment. The power control system 1000 according to the second embodiment is basically the same as the power control system 1000 according to the first embodiment with respect to the physical configuration.

First, the basic function of the power mode setting device 310 according to the second embodiment will be described with reference to FIG. Functionally, the power mode setting device 310 functionally includes a determination information acquisition unit 301, a schedule determination unit 302, a power mode setting unit 303, a storage amount acquisition unit 305, a predicted charge amount information storage unit 306, an event An information storage unit 307.

The schedule determination unit 302 determines a schedule based on the determination information acquired by the determination information acquisition unit 301. The schedule determination unit 302 includes, for example, a CPU 31.

The storage amount acquisition unit 305 acquires the storage amount stored in the storage battery 210. The power storage amount acquisition unit 305 acquires, for example, information indicating the power storage amount measured by the power storage amount measurement unit 140 (hereinafter referred to as “power storage amount information” as appropriate) from the power control apparatus 100. The power storage amount acquisition unit 305 includes, for example, a CPU 31 and an out-of-home interface 37 (or in-home interface 36).

The determination information acquisition unit 301 acquires information indicating the use start time as the determination information. The use start time is a time when the use of the electric vehicle 211 that runs using the power supplied from the storage battery 210 as a power source is started. The determination information acquisition unit 301 can acquire determination information indicating the use start time from an event information storage unit 307 described later.

Here, the schedule determination unit 302 determines a schedule so that the storage battery 210 is in a state in which the target storage amount is accumulated by the use start time, based on the storage amount acquired by the storage amount acquisition unit 305. The target power storage amount is, for example, a power storage amount that does not hinder the use of the electric vehicle 211. In the present embodiment, the target power storage amount is the maximum power storage amount of the storage battery 210.

The schedule determination unit 302 predicts the final charge start time based on the stored electricity amount acquired by the stored electricity amount acquisition unit 305. The final charging start time is the latest time among the times when the storage battery 210 can be brought into a state in which the target storage amount is accumulated by the use start time. The schedule determination unit 302 determines a schedule in which the power mode in the period from the charge start time to the use start time is a power mode for charging the storage battery 210. The charging start time is a time before the last charging start time by a margin time. The allowance time is preferably about 1 hour, for example. As described above, the schedule determination unit 302 determines a schedule for causing the storage battery 210 to start charging with a schedule having a certain margin so as to ensure that the storage battery 210 stores the target storage amount by the use start time. .

The predicted charge amount information storage unit 306 stores predicted charge amount information indicating the charge amount predicted to be able to charge the storage battery 210 for each period. Note that the predicted charge amount information includes the storage amount measured by the storage amount measurement unit 140, the power consumption of the electric device 400 measured by the power measurement device 500, and the power generation of the photovoltaic power generation panel 220 measured by the power measurement device 500. It is obtained based on power, time information acquired by the RTC 35, information indicating contract power stored in the flash memory 34, and the like. The predicted charge amount information storage unit 306 includes a flash memory 34, for example.

Here, the schedule determination unit 302 predicts the final charge start time based on the storage amount acquired by the storage amount acquisition unit 305 and the predicted charge amount information stored in the predicted charge amount information storage unit 306. Can do. Typically, the schedule determination unit 302 calculates the integrated value by integrating the estimated charge amount retroactively from the use start time, and determines the time when the sum of the integrated value and the charge amount at the current time exceeds the target charge amount. Predict the final charge start time.

Moreover, the schedule determination part 302 performs the process which estimates the last charge start time in a predetermined period, and the process which discriminate | determines whether the charge start time based on the estimated last charge start time is passed. be able to. Here, when it is determined that the charging start time has passed, the schedule determination unit 302 determines a schedule in which the power mode in the period from the current time to the use start time is a power mode for charging the storage battery 210. It seems that the final charge start time can be predicted and determined once. However, the amount of power stored in the storage battery 210 due to power consumption by the electric device 400 and power generation by the solar power generation panel 220 changes with the passage of time. Accordingly, it is expected that the accuracy of the final charge start time can be improved by repeatedly predicting the final charge start time at a predetermined cycle.

The event information storage unit 307 stores event information. The event information is information including a use start time at which use of the electric vehicle 211 is started. The event information is information received from the user or the like by the power mode setting device 310 that is a home controller having a calendar function. The event information storage unit 307 includes a flash memory 34, for example.

Next, with reference to FIG. 12, the relationship between the maximum power consumption and the chargeable power amount will be described.

The maximum power consumption is the maximum value of power consumed by the electric device 400 in the past in a certain period. The maximum power consumption is, for example, the maximum value of the power consumed by the electric device 400 in the past week in a certain time zone. That is, the maximum power consumption in a time zone with a large power consumption is a relatively large value. On the other hand, the maximum power consumption in a time zone with low power consumption is a relatively small value. Note that the maximum power consumption may be managed not for each time zone but for each time zone for each day of the week or for each time zone for each season.

The chargeable electric energy is the electric energy that can be charged in the storage battery 210 in a certain period. The chargeable electric energy is, for example, the electric energy that can charge the storage battery 210 in a certain time zone. Here, the chargeable power amount is basically a value obtained by subtracting the consumed power amount from the suppliable power amount. In the present embodiment, the chargeable power amount is estimated to be a value obtained by subtracting the maximum power consumption amount from the contract power amount.

The contract power amount is the maximum suppliable power amount determined by a contract with the electric power company, and is the maximum power amount supplied from the commercial power source 230. It is assumed that the contract power amount is the same in any time zone. Therefore, the chargeable power amount in the time zone where the maximum power consumption amount is large becomes small, and the chargeable power amount in the time zone where the maximum power consumption amount is small becomes large.

In this embodiment, in order to facilitate understanding, it is assumed that the amount of power that can be supplied does not include the amount of power supplied by the solar power generation panel 220. When the amount of power supplied by the solar power generation panel 220 is easy to estimate, the amount of power supplied by the solar power generation panel 220 may be included in the amount of power that can be supplied.

FIG. 12 shows that the maximum power consumption at time t is Wcsmax [t], the contract power at time t is Wspmax, and the chargeable power at time t is Wcg [t]. ing.

Next, the timing at which the schedule is set will be described with reference to FIG.

First, an event using the electric vehicle 211 is registered in the power mode setting device 300 which is a home controller. Here, at the check start time (Tckst), a check is started as to whether or not the current time (Tnow) exceeds the charge start time (Tcgst). The check start time is a time that is a maximum charge time before the use start time (Tuest). The use start time is a time when use of the electric vehicle 211 is started. The maximum charging time is the maximum time required to charge the storage battery 210. In other words, if the maximum charging time elapses after charging of the storage battery 210 is started, it is guaranteed that the storage battery 210 is charged by the target power amount (typically, the maximum power amount). The maximum charging time can be set to 24 hours, for example.

Also, the charging start time is a time before the last charging start time by a margin time. The allowance time is a time that is provided to ensure that the storage battery 210 is storing the target power amount at the use start time. The allowance time can be set to 1 hour, for example. The final charge start time is a time that is an estimated charge time before the use start time. The predicted charging time is a predicted value of the time required for the storage battery 210 to store the target power amount.

Therefore, the charging start time can be estimated by estimating the predicted charging time. However, the amount of power stored in the storage battery 210, which is necessary for obtaining the predicted charging time, changes with the passage of time. Therefore, the power mode setting device 310 executes a process for obtaining the charge start time at each check time (Tck) that arrives at a predetermined cycle, and determines that the check time has passed the obtained charge start time. If so, the charging start time is confirmed. Note that a schedule for setting the EV charging mode is set in the power control apparatus 100 from the confirmed charging start time to the use start time. According to this method, the accuracy of the charging start time is improved, and the charging start time is prevented from being too early or too late.

Next, the power mode setting process executed by the power mode setting device 310 according to the present embodiment will be described in detail with reference to the flowchart shown in FIG. The power mode setting device 310 starts the power mode setting process shown in FIG. 14 in response to the power being turned on.

First, the CPU 31 executes an initialization process (step S201). For example, the CPU 31 stops the setting timer.

When the CPU 31 completes the process of step S201, it determines whether or not there is an event registration instruction (step S202). For example, the CPU 31 determines whether or not the event registration instruction information transmitted from the terminal device 600 has been received by the in-home interface 36 or the out-of-home interface 37. The event registration instruction information is information indicating an event registration instruction. Here, the terminal apparatus 600 transmits event registration instruction information to the power mode setting apparatus 300 via the in-home interface 66 or the out-of-home interface 67 in response to the event registration instruction from the user being received by the touch screen 68. To do.

When it is determined that there is an event registration instruction (step S202: YES), the CPU 31 registers an event (step S203). For example, the CPU 31 causes the terminal device 600 to display a screen for allowing the user to register an event, and accepts event registration. The terminal device 600 transmits the event information acquired by registering the event to the power mode setting device 310. On the other hand, the CPU 31 stores the event information transmitted from the terminal device 600 in the flash memory 34.

When it is determined that there is no event registration instruction (step S202: NO), or when the process of step S203 is completed, the CPU 31 determines whether the schedule is being set (step S204). In addition, CPU31 can discriminate | determine that it is under schedule setting, when it discriminate | determines that the present time is the time between the charging start time which has been confirmed and use start time.

When it is determined that the schedule is not being set (step S204: NO), the CPU 31 determines whether there is an event registered using the electric vehicle 211 (step S205). For example, the CPU 31 can determine whether or not there is an event registered using the electric vehicle 211 with reference to the event information stored in the flash memory 34.

CPU31 will perform a schedule setting process, if it determines with there being registration of the event using the electric vehicle 211 (step S205: YES) (step S206). Hereinafter, the schedule execution process will be described in detail with reference to the flowchart shown in FIG.

First, the CPU 31 determines whether or not Tnow> Tckst is satisfied (step S301). That is, the CPU 31 determines whether or not the current time (Tnow) exceeds the check start time (Tckst). Note that the check start time (Tckst) = use start time (Tusest) −24 hours. Note that the use start time is indicated by event information stored in the flash memory 34.

CPU31 will discriminate | determine whether it is Tnow = Tck, if it discriminate | determines that it is Tnow> Tckst (step S301: YES) (step S302). That is, the CPU 31 determines whether or not the current time (Tnow) is the check time (Tck). The check time (Tck) is a time that arrives regularly (for example, every minute) after the check start time (Tckst). The CPU 31 can determine whether or not the current time (Tnow) is the check time (Tck) using a timer similar to the setting timer.

If the CPU 31 determines that Tnow = Tck (step S302: YES), it executes Tcglast ← Tustest (step S303). That is, the CPU 31 sets the use start time (Tustest) as the initial value at the final charge start time (Tcglast).

CPU31 will perform Wbuf ← 0, if the process of step S303 is completed (step S304). That is, the CPU 31 sets 0 as the initial value for the power amount buffer value (Wbuf).

CPU31 will complete | finish the process of step S304, and will discriminate | determine whether it is Wbuf> Wcgmax-Wnow (step S305). That is, the CPU 31 determines whether or not the power amount buffer value (Wbuf) is larger than a value obtained by subtracting the current charge amount (Wnow) from the maximum charge amount (Wcgmax).

When determining that Wbuf> Wcgmax−Wnow is not satisfied (step S305: NO), the CPU 31 executes Tcglast ← Tcglast-1 (step S306). That is, the CPU 31 sets the final charge start time (Tcglast) to the time one minute before.

CPU31 will perform Wbuf ← Wbuf + Wcg [t] / 60, if the process of step S306 is completed (step S307). That is, the CPU 31 increases the power amount buffer value (Wbuf) by the chargeable power amount per minute of the chargeable power amount (Wcg [t]) in the time period t. Note that t indicates the time zone of the last charge start time (Tcglast). For example, t is 13 when the last charge start time (Tcglast) is 13:42. When completing the process in step S307, the CPU 31 returns the process to step S305.

On the other hand, when determining that Wbuf> Wcgmax−Wnow (step S305: YES), the CPU 31 determines whether Tnow> Tcglast-60 (step S308). That is, the CPU 31 determines whether or not the current time (Tnow) exceeds the time one hour before the final charge start time (Tcglast), that is, the charge start time (Tcgst).

If the CPU 31 determines that Tnow> Tcglast-60 (step S308: NO), it executes Tcgst ← Tnow (step S309). That is, the CPU 31 sets the current time (Tnow) as the charging start time (Tcgst).

CPU31 will set a schedule, if the process of step S309 is completed (step S310). Specifically, the CPU 31 sets a schedule for setting the EV charging mode in the power control apparatus 100 as a schedule to be adopted during the period from the charging start time (Tcgst) to the use start time (Tustest).

CPU31 will set EV charge mode to the power control apparatus 100, if the process of step S310 is completed (step S311). Specifically, the CPU 31 transmits power mode information designating the EV charging mode to the power control apparatus 100.

CPU31 will start the timer for a setting, if the process of step S311 is completed (step S312). When it is determined that Tnow> Tckst is not satisfied (step S301: NO), when it is determined that Tnow = Tck is not satisfied (step S302: NO), when it is determined that Tnow> Tcglast-60 is not satisfied (step S308: NO), Or when the process of step S312 is completed, a schedule setting process is completed.

When it is determined that the schedule is being set (step S204: YES), the CPU 31 determines whether Tnow> Test (step S207). That is, the CPU 31 determines whether or not the current time (Tnow) exceeds the use start time (Tustest).

CPU31 discriminate | determines whether the value of the timer for setting is more than predetermined value, when it determines with it not being Tnow> Test (step S207: NO) (step S208). CPU31 sets EV charge mode, when it determines with the value of the timer for setting being more than predetermined value (step S208: YES) (step S209). Specifically, the CPU 31 transmits power mode information designating the EV charging mode to the power control apparatus 100. When completing the process in step S209, the CPU 31 restarts the setting timer (step S210).

On the other hand, if the CPU 31 determines that Tnow> Test (step S207: YES), the CPU 31 cancels the schedule (step S211). That is, the CPU 31 ends the process of transmitting power mode information specifying the EV charging mode to the power control apparatus 100.

CPU31 will stop the timer for a setting, if the process of step S211 is completed (step S212).
