In addition, the charging control device 100 controls discharging by the storage battery 310. The supply destination of the electric power discharged from the storage battery 310 is the drive unit of the electric vehicle 300 or the home appliance 500. The charging control apparatus 100 can cause the storage battery 310 to discharge the power consumed by the home device 500 while the storage battery 310 is connected to the home device 500. In this embodiment, in order to facilitate understanding, it is assumed that no power is supplied (sold) from the photovoltaic power generation panel 200 or the storage battery 310 to the commercial power source 400.

  The photovoltaic power generation panel 200 converts solar energy into electrical energy. The photovoltaic power generation panel 200 supplies DC power obtained by power generation to the DC / AC converter 610.

  The electric vehicle 300 is a vehicle that uses electric energy stored in the storage battery 310 as a power source. The electric vehicle 300 includes a storage battery 310, a watt-hour meter 320, and a control unit 330.

  The storage battery 310 stores the power supplied from the photovoltaic power generation panel 200 or the commercial power source 400. The power stored in the storage battery 310 is mainly used as a power source for the electric vehicle 300, but may be consumed by the home appliance 500. The power supplied from the external device to the storage battery 310 is DC power. Further, the power supplied from the storage battery 310 to an external device is DC power. The storage battery 310 is charged or discharged by the control unit 330 controlled by the charge control device 100.

  The watt-hour meter 320 measures the amount of power stored in the storage battery 310 (hereinafter referred to as “remaining amount”). The control unit 330 includes an ECU (Engine Control Unit) and controls the operation of the entire electric vehicle 300. Further, the control unit 330 can communicate with the charge control device 100. For example, the control unit 330 notifies the charge control device 100 of the remaining amount of the storage battery 310. In addition, the control unit 330 notifies the charge control device 100 whether or not the storage battery 310 is connected to the photovoltaic power generation panel 200 or the commercial power source 400.

  The storage battery 310 is connected to the photovoltaic power generation panel 200 and the commercial power source 400 when the electric vehicle 300 arrives at home and is connected to a charging gun provided in the charging control system 1000. On the other hand, the storage battery 310 is not connected to the photovoltaic power generation panel 200 and the commercial power source 400 when the electric vehicle 300 leaves from the house and is no longer connected to the charging gun provided in the charging control system 1000. Further, the control unit 330 charges the storage battery 310 or causes the storage battery 310 to discharge in accordance with a control signal received from the charge control device 100.

  The commercial power source 400 is a power source for supplying power to consumers by an electric power company or the like. The power supplied from the commercial power source 400 is AC power. In the present embodiment, it is assumed that the consumer can buy power from the power company but cannot sell power to the power company. That is, in this embodiment, power flows from the commercial power source 400 to the consumer, but power does not flow backward from the consumer to the commercial power source 400.

  In-home device 500 is a device that operates using electric energy as a power source. Home appliance 500 operates with power supplied from at least one of photovoltaic power generation panel 200, storage battery 310, and commercial power source 400. In this embodiment, the in-home device 500 is assumed to operate with AC power. Home appliance 500 is, for example, an air conditioner, a water heater, an electric stove, a rice cooker, a lighting device, an electric carpet, or the like. In this embodiment, an example in which the number of in-home devices 500 is one will be described for easy understanding. Note that the in-home device 500 in the present embodiment may be considered as an assembly of two or more electric devices.

  The DC / AC converter 610 converts the DC power supplied from the solar power generation panel 200 into AC power. The AC power generated by the conversion by the DC / AC converter 610 is stored in the storage battery 310 or consumed by the home device 500.

  The DC / AC converter 620 converts the DC power supplied from the storage battery 310 into AC power. The AC power generated by the conversion by the DC / AC converter 620 is consumed by the home appliance 500. Further, the DC / AC converter 620 converts AC power supplied from the photovoltaic power generation panel 200 or the commercial power source 400 into DC power. The direct current power generated by the conversion by the DC / AC converter 620 is stored in the storage battery 310.

  The wattmeter 710 measures the value of power generated by the solar power generation panel 200 (hereinafter referred to as “generated power value” as appropriate). The generated power value measured by the wattmeter 710 is supplied to the charging control device 100.

  The power meter 720 measures the value of power consumed by the home appliance 500 (hereinafter referred to as “power consumption value” as appropriate). The power consumption value measured by the wattmeter 720 is supplied to the charging control device 100.

  Next, the physical configuration of the charging control apparatus 100 will be described with reference to FIG. As shown in FIG. 2, the charge control device 100 includes a CPU (Central Processing Unit) 11, a ROM (Read Only Memory) 12, a RAM (Random Access Memory) 13, a flash memory 14, an RTC (Real Time Clock) 15, a touch. A screen 16 and an external device interface 17 are provided. The components included in the charging control apparatus 100 are connected to each other via a bus.

  The CPU 11 controls the overall operation of the charge control device 100. The CPU 11 operates according to a program stored in the ROM 12 and uses the RAM 13 as a work area. The ROM 12 stores a program and data for controlling the overall operation of the charging control apparatus 100. The RAM 13 functions as a work area for the CPU 11. That is, the CPU 11 temporarily writes programs and data in the RAM 13 and refers to these programs and data as appropriate.

  The flash memory 14 is a nonvolatile memory that stores various types of information. The RTC 15 is a time measuring device. The RTC 15 includes, for example, a battery and keeps timing while the power supply of the charging control device 100 is off. The RTC 15 includes an oscillation circuit including a crystal oscillator, for example.

  The touch screen 16 detects a touch operation performed by the user and supplies a signal indicating the detection result to the CPU 11. The touch screen 16 displays an image based on the image signal supplied from the CPU 11 or the like. As described above, the touch screen 16 functions as a user interface of the charging control device 100.

  The external device interface 17 is an interface for connecting the electric vehicle 300, the power meter 710, and the power meter 720 to the charging control device 100. The external device interface 17 supplies charge / discharge command values to the electric vehicle 300 according to the control by the CPU 11. The charge / discharge command value is a value of power to be charged in the storage battery 310 or a value of power to be discharged to the storage battery. Further, the CPU 11 acquires the remaining amount measured by the watt hour meter 320, the generated power value measured by the watt meter 710, and the power consumption value measured by the watt meter 720 via the external device interface 17. Can do. The external device interface 17 may be an interface for serial communication such as USB (Universal Serial Bus) or IEEE (Institute of Electrical and Electronic Engineers) 1394, or a LAN interface such as NIC (Network Interface Card). Also good.

  Next, basic functions of the charging control apparatus 100 will be described with reference to FIG. The charging control device 100 is a device that controls charging of the storage battery 310 by the commercial power source 400 when the storage battery 310 mounted on the electric vehicle 300 is connected to the commercial power source 400 that charges the storage battery 310. Functionally, the charge control device 100 is configured to include a state determination unit 101, a remaining amount acquisition unit 102, a remaining amount determination unit 103, a charge control unit 104, a delay allowable time reception unit 105, a discharge allowable time zone reception unit 106, a charge permission A time zone reception unit 107, a setting reception unit 108, a storage unit 109, and a power value acquisition unit 110 are provided.

  The state determination unit 101 determines whether or not the storage battery 310 is connected to the commercial power source 400 based on connection state information or the like. The connection state information is information indicating whether or not the storage battery 310 is connected to the commercial power source 400, and is information that the external device interface 17 receives from the control unit 330. The state determination unit 101 includes, for example, a CPU 11.

  The remaining amount acquisition unit 102 acquires the remaining amount of the storage battery 310. The remaining amount of the storage battery 310 is the remaining amount measured by the watt hour meter 320. The remaining amount acquisition unit 102 includes, for example, an external device interface 17.

  The remaining amount determination unit 103 determines whether or not the remaining amount acquired by the remaining amount acquisition unit 102 has reached the target remaining charge amount. The target remaining charge is a target remaining amount at the time of charging, and is an upper limit value of the remaining amount at the time of charging. The target charge remaining amount is set to, for example, about 80% of the remaining amount at the time of full charge. The reason why the target charge remaining amount is not set to the remaining amount at the time of full charge is that the life of the storage battery 310 is likely to be shortened when charged and discharged in a state close to full charge. The remaining amount determination unit 103 includes, for example, a CPU 11.

  The charge control unit 104 is configured to charge the storage battery 310 so as to charge the storage battery 310 while it is determined that the remaining amount acquired by the remaining amount determination unit 103 has not reached the target remaining charge amount in the allowable charging time zone. Control the charging. The charge allowable time zone is a time zone in which charging of the storage battery 310 by the commercial power source 400 is allowed. The allowable charging time zone is set, for example, in a time zone (for example, 23: 00 to 07:00) where late-night charges are applied to the purchased power. Note that, in the allowable charging time zone, the storage battery 310 may be charged by the photovoltaic power generation panel 200, but the discharge of the storage battery 310 is prohibited. The charging control unit 104 includes, for example, a CPU 11 and an external device interface 17.

  Here, the charging control unit 104 starts charging when the storage battery 310 starts to be charged within the allowable charging time period, and the remaining charge acquired at the end time of the allowable charging time period has not reached the target remaining charging capacity. The charging of the storage battery 310 is controlled so that the charging of the storage battery 310 is continued after the end time of the time zone. As described above, the charging control unit 104 extends the charging of the storage battery 310 when the remaining amount of the storage battery 310 does not reach the target remaining charge amount within the allowable charging time zone due to the arrival delay of the electric vehicle 300. Can do. Conditions and methods for extending the charging of the storage battery 310 by the charging control unit 104 can be adjusted as appropriate.

  For example, the charging control unit 104 allows charging even when the charging of the storage battery 310 is started within the allowable charging time period and the remaining amount acquired at the end time of the allowable charging time period has not reached the target remaining charging amount. When charging of the storage battery 310 is started after a predetermined delay allowable time has elapsed from the start time of the time zone, the charging of the storage battery 310 can be controlled to stop the charging of the storage battery 310. In other words, the charge control unit 104 stores the storage battery after the end time of the allowable charging time zone only when the electric vehicle arrives and charging starts before the allowable delay time elapses from the start time of the allowable charging time zone. The charging of 310 can be continued. Note that the charging control unit 104 is the time at which charging is started when the state determination unit 101 first determines that the storage battery 310 is connected to the commercial power source 400 in the allowable charging time zone. Can be recognized.

  The allowable delay time receiving unit 105 receives the specification of the allowable delay time. For example, if the user wants to charge the storage battery 310 as much as possible even if an electric charge is charged, the user sets a longer allowable delay time. On the other hand, if the user wants to refrain from charging the storage battery 310 if an electric charge is required, the user sets a short allowable delay time. The allowable delay time can be arbitrarily set between 0 hour and 24 hours. The allowable delay time receiving unit 105 includes, for example, the touch screen 16.

  Further, the remaining amount determining unit 103 can further determine whether or not the remaining amount acquired by the remaining amount acquiring unit 102 has reached the target discharge remaining amount. The target discharge remaining amount is a target remaining amount at the time of discharging, and is a lower limit value of the remaining amount at the time of discharging. The remaining amount of discharge charge is set to a remaining amount of about 20% of the remaining amount at the time of full charge, for example. The reason why the target discharge remaining amount is not set to 0% of the remaining amount at the time of full charge is that the life of the storage battery 310 is likely to be shortened when the remaining amount is charged and discharged in a state close to zero.

  Here, the charge control unit 104 connects the storage battery 310 to the commercial power source 400 by the state determination unit 101 in the discharge allowable time zone that does not overlap with the charge allowable time zone and the start time does not coincide with the end time of the charge allowable time zone. The storage battery 310 is discharged so that the storage battery 310 is discharged while it is determined that the remaining amount acquired by the remaining amount determination unit 103 has not reached the target discharge remaining amount. Further control is possible. The allowable discharge time zone is a time zone in which the storage battery 310 is allowed to discharge a shortage of power consumed by the solar power generation panel 200 among the power consumption of the home appliance 500. The allowable discharge time zone is, for example, a part of a time zone (for example, 09: 0 to 23:00) in a time zone (for example, 07: 0 to 23:00) in which daytime charges are applied to purchased power. ). In the discharge allowable time zone, in principle, charging of the storage battery 310 by the photovoltaic power generation panel 200 is allowed, but charging of the storage battery 310 by the commercial power source 400 is prohibited.

  Here, the charging control unit 104 starts charging when the storage battery 310 starts to be charged within the allowable charging time period, and the remaining charge acquired at the end time of the allowable charging time period has not reached the target remaining charging capacity. After the end of the time period, charging of the storage battery 310 is continued until the discharge allowable time period is reached or until it is determined that the remaining amount acquired by the remaining amount determination unit 103 has reached the target remaining charge amount. Thus, the charging of the storage battery 310 can be controlled. That is, when the charging is not completed, the charging control unit 104 allows the storage battery 310 to be charged in the charging / discharging suspension time zone, which is the time zone from the end time of the allowable charging time zone to the allowable discharging time zone. On the other hand, even when the charging is not completed, the charging control unit 104 does not allow the storage battery 310 to be charged in the discharge allowable time zone. In principle, the charge / discharge hold time zone is a time zone during which charging / discharging of the storage battery 310 is prohibited. The charge / discharge hold time zone is basically a time zone in which the state in which the remaining amount of the storage battery 310 is the target remaining charge amount is maintained. It is preferable that the time when it is determined whether or not to use the electric vehicle 300 is set as the end time of the charge / discharge suspension time zone.

  Further, the charge control unit 104 has determined that the remaining amount acquired by the remaining amount determination unit 103 has not reached the target discharge remaining amount in the discharge allowable time zone that is a time zone other than the charge allowable time zone. Meanwhile, the discharge of the storage battery 310 can be further controlled so that the storage battery 310 is discharged.

  Here, the charging control unit 104 starts charging when the storage battery 310 starts to be charged within the allowable charging time period, and the remaining charge acquired at the end time of the allowable charging time period has not reached the target remaining charging capacity. After the end of the time period, charging of the storage battery 310 is continued until it is determined that the remaining amount acquired by the remaining amount determination unit 103 has reached the target remaining charge amount even in the discharge allowable time period. In addition, the charging of the storage battery 310 can be controlled. That is, when the time zone other than the allowable charging time zone is set as the allowable discharging time zone and there is no charging / discharging holding time zone, the charging control unit 104 continues to charge the storage battery 310 even in the allowable discharging time zone. Can do.

  The discharge allowable time zone receiving unit 106 receives designation of the discharge allowable time zone. The allowable discharge time zone is specified by, for example, the start time of the allowable discharge time zone and the end time of the allowable discharge time zone. The discharge allowable time zone reception unit 106 includes, for example, the touch screen 16. The allowable charging time zone receiving unit 107 receives designation of the allowable charging time zone. The allowable charging time zone is specified by, for example, the start time of the allowable charging time zone and the end time of the allowable charging time zone. The chargeable time zone reception unit 107 includes, for example, a touch screen 16.

  The setting reception unit 108 receives various setting values. For example, the setting reception unit 108 receives specification of an operation mode of the charge control device 100, specification of a target remaining charge amount, specification of a target discharge remaining amount, and the like from the user. The setting reception unit 108 includes, for example, the touch screen 16.

  The storage unit 109 stores various types of information. For example, the storage unit 109 includes information indicating the allowable delay time received by the allowable delay time receiving unit 105, information indicating the allowable discharge time zone received by the allowable discharge time zone receiving unit 106, and the allowable charge time zone receiving unit 107. The information indicating the permissible charging time zone received by, and the information indicating the various setting values received by the setting receiving unit 108 are stored. The storage unit 109 includes, for example, a flash memory 14.

  The power value acquisition unit 110 acquires the power generation value of the photovoltaic power generation panel 200 and the power consumption value of the home appliance 500. The power value acquisition unit 110 includes, for example, an external device interface 17.

  In addition, the charge control unit 104 determines that the storage battery 310 is connected to the commercial power source 400 by the state determination unit 101 in the charge allowable time zone, and the remaining amount acquired by the remaining amount determination unit 103 is the target charge. While it is determined that the remaining amount has not been reached, the charging of the storage battery 310 can be controlled so that the storage battery 310 is charged. Thus, the charge control unit 104 can control the charging of the storage battery 310 only when the storage battery 310 is connected to the commercial power source 400.

  Next, an operation mode of the charging control apparatus 100 will be described with reference to FIGS. 4, 5, and 6. As operation modes, there are a normal mode, a simple setting mode, and an individual setting mode. The normal mode is a mode in which the charging of the storage battery 310 is not extended even when the charging is not completed at the end time of the allowable charging time zone. Both the simple setting mode and the individual setting mode are modes in which the charging of the storage battery 310 is extended when the charging is not completed at the end time of the allowable charging time period.

  In the simple setting mode, only designation of the allowable charging time zone is accepted, and a time zone other than the allowable charging time zone is automatically set as the allowable discharging time zone. Therefore, there is no charge / discharge hold time zone in the simple setting mode. In the simple setting mode, if the charging is not completed at the end time of the allowable charging time period, the storage battery 310 may continue to be charged even in the allowable discharging time period. On the other hand, in the individual setting mode, the allowable charging time zone and the allowable discharging time zone are individually specified. Therefore, in the simple setting mode, there is basically a charge / discharge hold time zone. In the individual setting mode, when the charging is not completed at the end time of the allowable charging time zone, the charging of the storage battery 310 may continue in the charging / discharging holding time zone, but in the allowable discharging time zone, Charging does not continue.

  FIG. 4 is a diagram illustrating a charging control process when the charging start is delayed in the normal mode. In the example shown in FIG. 4, the allowable charging time zone is from 23:00 to 07:00 on the next day, the charging / discharging holding time zone is from 07:00 to 09:00, and from 09:00 to 23:00. Is the allowable discharge time zone. Here, in the normal mode, charging starts at 02:00, and when charging is not completed by 07:00, charging is stopped at 07:00, which is the end time of the allowable charging time zone. The delay in the start of charging means that the electric vehicle 300 arrives after the start time of the allowable charging time period has passed, the storage battery 310 is connected to the commercial power source 400, and charging of the storage battery 310 is started. . Although FIG. 4 shows an example in which the charge / discharge hold time zone is provided, even when the charge / discharge hold time zone is not provided, charging is stopped at the end time of the charge allowable time zone. It is.

  FIG. 5 is a diagram illustrating a charging control process when charging start is delayed in the simple setting mode. In the example shown in FIG. 5, the allowable charging time zone is from 23:00 to 07:00 on the next day, and the allowable discharging time zone is from 07:00 to 23:00. Here, in the simple setting mode, charging is started by the time when the allowable delay time has elapsed from the start time of the allowable charging time zone (hereinafter referred to as “permissible delay time”), and before the end time of the allowable charging time zone. When the charging is not completed, the charging is continued even after the end time of the allowable charging time period. In the simple setting mode, charging is started after the allowable delay time, and when charging is not completed by the end time of the allowable charging time zone, the charging is stopped at the end time of the allowable charging time zone.

  For example, when charging is started at 01:00 before 02:00, which is the allowable delay time, and charging is not completed by 07:00, which is the end time of the allowable charging time period, charging is completed at 08:00. Charging is continued until. On the other hand, for example, when charging is started at 03:00, which is past the allowable delay time of 02:00, and charging is not completed by 07:00, which is the end time of the allowable charging time zone, Charging is stopped at 07:00, which is the end time.

  FIG. 6 is a diagram illustrating a charging control process when the charging start is delayed in the individual setting mode. In the example shown in FIG. 6, the allowable charging time zone is from 23:00 to 07:00 the next day, the charging / discharging holding time zone is from 07:00 to 09:00, and from 09:00 to 23:00. Is the allowable discharge time zone. Here, in the individual setting mode, charging is started by the delay allowable time, and if charging is not completed by the end time of the allowable charging time period, the charging is continued even after the end time of the allowable charging time period. The However, in the individual setting mode, at the end time of the charge / discharge hold time zone, that is, the start time of the discharge allowable time zone, the charge is stopped even if the charge is not completed. In the individual setting mode, charging is started after the allowable delay time, and when charging is not completed by the end time of the allowable charging time zone, the charging is stopped at the end time of the allowable charging time zone.

  For example, if charging is started at 00:00 before 02:00, which is the allowable delay time, and charging is not completed by 07:00, which is the end time of the allowable charging time period, charging is completed at 08:00. Charging is continued until. On the other hand, if charging is started at 01:30 before 02:00, which is the allowable delay time, and charging is not completed by 07:00, which is the end time of the allowable charging time period, the charging / discharging suspension time period ends. Charging is continued until 09:00, which is the time, but charging is stopped at 09:00, which is the start time of the discharge allowable time zone, regardless of whether charging is completed. Also, for example, when charging is started at 03:00, which is past the allowable delay time of 02:00, and charging is not completed by 07:00, which is the end time of the allowable charging time zone, Charging is stopped at 07:00, which is the end time.

  Next, a setting process executed by the charging control device 100 will be described with reference to a flowchart shown in FIG. For example, the charging control apparatus 100 starts the setting process illustrated in FIG. 7 in response to an operation for instructing the start of the setting process being received by the touch screen 16. The setting process is a process for setting various setting values based on an operation by the user.

  First, the CPU 11 accepts designation of extended charge settings (step S101). For example, the CPU 11 selects “with extended charge setting” and “without extended charge setting” from the touch screen 16 that has received an operation for designating either “with extended charge setting” or “without extended charge setting”. The extension charge setting information which shows either of these is acquired. The CPU 11 stores the acquired extended charge setting information in the flash memory 14. The designation of “with extended charging setting” means that either the simple setting mode or the individual setting mode is designated as the operation mode. The designation of “no extended charge setting” means that the normal mode is designated as the operation mode.

  CPU11 will discriminate | determine whether there exists extended charge setting, if the process of step S101 is completed (step S102). For example, the CPU 11 determines whether there is an extended charge setting based on the extended charge setting information stored in the flash memory 14.

  When the CPU 11 determines that there is no extended charge setting (step S102: NO), the CPU 11 accepts designation of a charge allowable time zone (step S103). For example, the CPU 11 obtains the start time of the charge allowable time zone and the end time of the charge allowable time zone from the touch screen 16 that has received an operation for designating the start time of the charge allowable time zone and the end time of the charge allowable time zone. The chargeable time zone information shown is acquired. The CPU 11 stores the acquired allowable charging time zone information in the flash memory 14.

  CPU11 will receive designation | designated of the discharge allowable time slot | zone, if the process of step S103 is completed (step S104). For example, the CPU 11 obtains the start time of the discharge allowable time zone and the end time of the discharge allowable time zone from the touch screen 16 that has received an operation for designating the start time of the discharge allowable time zone and the end time of the discharge allowable time zone. The discharge allowable time zone information shown is acquired. The CPU 11 stores the acquired discharge allowable time zone information in the flash memory 14.

  On the other hand, if the CPU 11 determines that there is an extended charge setting (step S102: YES), the CPU 11 accepts the setting mode designation (step S105). For example, the CPU 11 acquires setting mode information indicating either the simple setting mode or the individual setting mode from the touch screen 16 that has received an operation for designating either the simple setting mode or the individual setting mode. To do. The CPU 11 stores the acquired setting mode information in the flash memory 14.

  CPU11 discriminate | determines whether setting mode is simple setting mode, when the process of step S105 is completed (step S106). For example, the CPU 11 determines whether or not the setting mode is the simple setting mode based on the setting mode information stored in the flash memory 14.

  When the CPU 11 determines that the setting mode is the simple setting mode (step S106: YES), the CPU 11 accepts designation of an allowable charging time zone (step S107). For example, the CPU 11 acquires the chargeable time zone information from the touch screen 16 that has received an operation for designating the start time of the chargeable time zone and the end time of the chargeable time zone. The CPU 11 stores the acquired allowable charging time zone information in the flash memory 14.

  CPU11 sets a discharge allowable time slot | zone automatically, when the process of step S107 is completed (step S108). For example, the CPU 11 sets a time zone other than the charge allowable time zone indicated by the charge allowable time zone information stored in the flash memory 14 as the discharge allowable time zone. The CPU 11 stores in the flash memory 14 discharge allowable time zone information indicating the discharge allowable time zone based on the start time of the discharge allowable time zone and the end time of the discharge allowable time zone.

  On the other hand, when the CPU 11 determines that the setting mode is not the simple setting mode (step S106: NO), the CPU 11 accepts designation of an allowable charging time zone (step S109). For example, the CPU 11 acquires the chargeable time zone information from the touch screen 16 that has received an operation for designating the start time of the chargeable time zone and the end time of the chargeable time zone. The CPU 11 stores the acquired allowable charging time zone information in the flash memory 14.

  CPU11 receives designation | designated of the discharge allowable time slot | zone, when the process of step S109 is completed (step S110). For example, the CPU 11 acquires discharge allowable time zone information from the touch screen 16 that has received an operation for designating the start time of the discharge allowable time zone and the end time of the discharge allowable time zone. The CPU 11 stores the acquired discharge allowable time zone information in the flash memory 14.

  When the CPU 11 completes the process of step S108 or step S110, it accepts designation of the allowable delay time (step S111). For example, the CPU 11 acquires allowable delay time information indicating the allowable delay time from the touch screen 16 that has received an operation for specifying the allowable delay time. The CPU 11 stores the acquired delay allowable time information in the flash memory 14. When completing the process in step S111, the CPU 11 completes the setting process.

  Next, a charging control process executed by the charging control device 100 will be described with reference to a flowchart shown in FIG. For example, the charging control apparatus 100 starts the setting process illustrated in FIG. 8 in response to an operation instructing the start of the charging control process being received by the touch screen 16. The charging control process is a process for controlling the charging of the storage battery 310. In the present embodiment, the charge control process includes a process for controlling the discharge of the storage battery 310. Further, it is assumed that the instruction to start the charging control process is made after the setting process is completed.

  First, the CPU 11 acquires the connection state of the storage battery (step S201). For example, the CPU 11 acquires connection state information received by the external device interface 17 from the control unit 330. The CPU 11 stores the acquired connection state information in the flash memory 14.

  CPU11 will discriminate | determine whether the storage battery 310 is connected to the commercial power source 400 etc., if the process of step S201 is completed (step S202). The commercial power source 400 and the like are the commercial power source 400 and the photovoltaic power generation panel 200. The CPU 11 can determine whether or not the storage battery 310 is connected to the commercial power source 400 or the like based on the connection state information stored in the flash memory 14.

  If CPU11 discriminate | determines that the storage battery 310 is not connected to the commercial power source 400 grade | etc., (Step S202: NO), it will return a process to step S201. On the other hand, when determining that the storage battery 310 is connected to the commercial power source 400 or the like (step S202: YES), the CPU 11 acquires the current time (step S203). For example, the CPU 11 acquires current time information indicating the current time from the RTC 15. The CPU 11 stores the acquired current time information in the flash memory 14.

  CPU11 will acquire the residual amount of the storage battery 310, if the process of step S203 is completed (step S204). For example, the CPU 11 can acquire the remaining amount information indicating the remaining amount measured by the watt hour meter 320 from the external device interface 17. The CPU 11 stores the acquired remaining amount information in the flash memory 14.

  CPU11 will acquire a generated electric power value and a power consumption value, if the process of step S204 is completed (step S205). For example, the CPU 11 can acquire the generated power value information indicating the generated power value measured by the power meter 710 and the consumed power value information indicating the power consumption value measured by the power meter 720 from the external device interface 17. it can. The CPU 11 stores the acquired power generation value information and power consumption value information in the flash memory 14.

  When completing the process of step S205, the CPU 11 determines whether or not there is an extended charge setting (step S206). For example, the CPU 11 determines whether there is an extended charge setting based on the extended charge setting information stored in the flash memory 14. When determining that there is no extended charge setting (step S206: NO), the CPU 11 executes normal mode processing (step S207). The normal mode process will be described below with reference to the flowchart shown in FIG.

  First, the CPU 11 determines whether or not it is a chargeable time zone (step S301). The CPU 11 determines whether or not the current time indicated by the current time information stored in the flash memory 14 is a time belonging to the allowable charging time zone indicated by the allowable charging time zone information stored in the flash memory 14. .

  When the CPU 11 determines that it is the allowable charging time zone (step S301: YES), it determines whether or not the remaining amount of the storage battery 310 is equal to or less than the target remaining charge (step S302). The CPU 11 determines whether or not the remaining amount indicated by the remaining amount information stored in the flash memory 14 is equal to or less than the target remaining charge amount indicated by the target remaining charge information stored in the flash memory 14. Note that both the target charge remaining amount information indicating the target remaining charge amount and the target discharge remaining amount information indicating the target discharge remaining amount are stored in the flash memory 14 before the charge control process is started. And The target charge remaining amount and target discharge remaining amount may be determined in advance by a program or the like, or may be specified by the user in the setting process.

  When the CPU 11 determines that the remaining amount of the storage battery 310 is equal to or less than the target remaining charge (step S302: YES), the CPU 11 instructs the storage battery 310 to charge (step S303). The charging instruction is an instruction for charging the storage battery 310 with the electric power supplied from the commercial power source 400. When completing the process in step S303, the CPU 11 completes the normal mode process.

  On the other hand, if the CPU 11 determines that it is not the allowable charging time zone (step S301: NO), the CPU 11 determines whether it is the allowable discharging time zone (step S304). The CPU 11 determines whether or not the current time indicated by the current time information stored in the flash memory 14 is a time belonging to the allowable discharge time zone indicated by the allowable discharge time zone information stored in the flash memory 14. .

  If the CPU 11 determines that it is within the discharge allowable time zone (step S304: YES), it determines whether or not the remaining amount of the storage battery 310 is equal to or greater than the target discharge remaining amount (step S305). The CPU 11 determines whether or not the remaining amount indicated by the remaining amount information stored in the flash memory 14 is equal to or greater than the target discharge remaining amount indicated by the target discharge remaining amount information stored in the flash memory 14.

  When the CPU 11 determines that the remaining amount of the storage battery 310 is equal to or greater than the target discharge remaining amount (step S305: YES), the CPU 11 instructs the storage battery 310 to discharge (step S306). The discharge instruction is an instruction to cause the storage battery 310 to discharge insufficient power. The insufficient power is calculated by subtracting the generated power value indicated by the generated power value information stored in the flash memory 14 from the consumed power value indicated by the consumed power value information stored in the flash memory 14. When completing the process of step S306, the CPU 11 completes the normal mode process.

  When the CPU 11 determines that the remaining amount of the storage battery 310 is not equal to or less than the target remaining charge amount (step S302: NO), or determines that it is not the allowable discharge time zone (step S304: NO), the remaining amount of the storage battery 310 is the target discharge. When it is determined that the remaining amount is not exceeded (step S305: NO), the storage battery 310 is instructed to prohibit charging / discharging (step S307). The instruction to prohibit charging / discharging is an instruction not to charge or discharge the storage battery 310. When completing the process in step S307, the CPU 11 completes the normal mode process. When the CPU 11 completes the normal mode process in step S207, the process returns to step S201.

  The method for determining whether or not the previous instruction is a charging instruction can be adjusted as appropriate. For example, the CPU 11 stores the latest instruction information indicating the latest instruction content in the flash memory 14 regardless of any of the charge instruction, the discharge instruction, and the charge / discharge prohibition instruction. Then, the CPU 11 can determine whether the previous instruction is a charge instruction, a discharge instruction, or a charge / discharge prohibition instruction based on the latest instruction information stored in the flash memory 14.

  When determining that the previous instruction is not a charging instruction (step S403: NO), the CPU 11 stores the current time as the charging start time (step S404). The CPU 11 stores charging start time information indicating the current time in the flash memory 14. The current time can be specified by the current time information stored in the flash memory 14.

Thus, it is determined whether or not the time is earlier than the allowable delay time indicated by the allowable delay time information stored in the flash memory 14. The allowable delay time is a time obtained by adding the allowable delay time indicated by the allowable delay time information to the start time of the charge start time period indicated by the allowable charge time zone information.

  When determining that the charging start time is within the allowable delay period (step S405: YES), the CPU 11 determines whether or not the previous instruction is a charging instruction (step S406).

When completing the process of step S411, the CPU 11 completes the simple setting mode process. CPU11 will return a process to step S201, if the simple setting mode process of step S209 is completed.

  On the other hand, when determining that the setting mode is not the simple setting mode (step S208: NO), the CPU 11 executes an individual setting mode process (step S210). The individual setting mode process will be described below with reference to the flowchart shown in FIG.

When the CPU 11 determines that it is the allowable charging time zone (step S501: YES), the CPU 11 determines whether or not the remaining amount of the storage battery 310 is equal to or less than the target remaining charge amount (step S502). When determining that the remaining amount of the storage battery 310 is equal to or less than the target remaining charge (step S502: YES), the CPU 11 determines whether the previous instruction is a charging instruction (step S503).

  When determining that the previous instruction is not a charging instruction (step S503: NO), the CPU 11 stores the current time as the charging start time (step S504). When the CPU 11 determines that the previous instruction is a charge instruction (step S503: YES), the CPU 11 instructs the storage battery 310 to charge when the process of step S504 is completed (step S505). When completing the process in step S505, the CPU 11 completes the individual setting mode process.

  On the other hand, if the CPU 11 determines that it is not the allowable charging time zone (step S501: NO), it determines whether it is the allowable discharging time zone (step S506). If the CPU 11 determines that it is the allowable discharge time zone (step S506: YES), it determines whether or not the remaining amount of the storage battery 310 is equal to or greater than the target discharge remaining amount (step S507). When the CPU 11 determines that the remaining amount of the storage battery 310 is equal to or greater than the target discharge remaining amount (step S507: YES), the CPU 11 instructs the storage battery 310 to discharge (step S508).

It is determined whether or not (step S509). When determining that the charging start time is within the allowable delay period (step S509: YES), the CPU 11 determines whether the previous instruction is a charging instruction (step S510). When determining that the previous instruction is a charge instruction (step S510: YES), the CPU 11 determines whether or not the remaining amount of the storage battery 310 is equal to or less than the target remaining charge (step S511).
