  Examples of the charging setting include setting charging power (W), setting a charging time (time from the start to the end of charging), setting a charging power amount (Wh), and the like.

  In the management table 61 shown in FIG. 2, there is no restriction on the time zone as the charge permission condition for the electric vehicle 20 having the ID of 2563254. Moreover, it is prescribed | regulated that a charge will be stopped when the charge amount of the storage battery 42 becomes 100% of chargeable amount, and the upper limit with respect to the charge amount of the storage battery 42 will be in the state which is not provided substantially. Yes. In addition, as a charge setting, neither charge power nor charge time is limited.

  For the electric vehicle 20 having an ID of 2349229, as a charging permission condition, a time period during which charging is permitted is limited from 23:00 to 7:00. Furthermore, there is an upper limit value that stops charging when the charge amount of the storage battery 42 reaches 80% of the chargeable amount. This setting is a setting that assumes a case where the storage battery 42 of the electric vehicle 20 is used as a home storage battery that stores nighttime power and is used during the daytime. In addition, as a charge setting, there is no restriction on the charging power, but there is a restriction that the charging time is 2 hours.

  For the electric vehicle 20 with ID 1119383, there is no restriction on the time zone as a charging permission condition, but the upper limit is that charging is stopped when the charge amount of the storage battery 42 reaches 50% of the chargeable amount. A value is provided. The charging power may be set based on the capacity of the storage battery 42 and the like.

When registering the ID of a desired electric vehicle 20 in the management table 61, the user may input the ID via the input unit 8, or the electric vehicle 20 is connected to the residential power management system 1 so as to be communicable. In such a state, it may be acquired from the electric vehicle 20.

  Further, the charging permission condition and the charging setting can be arbitrarily set and changed by the user via the input unit 8. Further, even if the ID is not registered, charging is permitted depending on the charging permission condition, but charging that is information (information for restricting charging to the electric vehicle 20) that explicitly specifies the electric vehicle 20 that is not permitted to be charged. The non-permission information may be recorded in the management table 61.

(Processing flow in residential power management system 1)
Next, an example of a processing flow in the house power management system 1 in the charging mode will be described. FIG. 3 is a flowchart illustrating an example of a process flow in the house power management system 1. Here, it is assumed that the charging mode has already been set according to a user instruction.

  First, when the electric vehicle 20 and the house power management system 1 are connected via the cable 16, signals (confirmation signal and response signal) for confirming connection between the communication unit 25 and the communication unit 4 are obtained. Transmission / reception is performed (S1).

  When the communication unit 25 and the communication unit 4 are wired by a communication line passing through the cable 16, the electric vehicle 20 and the house are confirmed by confirming that the communication unit 25 and the communication unit 4 can communicate with each other. It can be confirmed that the power management system 1 is connected. The transmission of the confirmation signal may be transmitted from the house power management system 1 to the electric vehicle 20 according to a user instruction, or transmitted when it is detected that the cable 16 is connected to the connector 14 and the connector 43. Also good. When receiving the confirmation signal, the control unit 22 transmits a response signal to the house power management device 2 via the communication unit 25.

  When the response signal is received, the authentication unit 31 of the house power management device 2 transmits an ID request signal for instructing transmission of the ID to the vehicle power management device 21 (S2).

  When receiving the ID request signal, the control unit 22 acquires the ID of the electric vehicle 20 on which the device is mounted from the storage unit 24 and transmits the acquired ID to the residential power management device 2.

  When the ID of the electric vehicle 20 is received (S3) (acquisition step), the authentication unit 31 compares the received ID with a plurality of IDs recorded in the management table 61 of the storage unit 6, and there is a match. Whether or not (first authentication step).

  If there is a matching ID (YES in S4), authentication unit 31 determines whether or not the charging permission condition indicated by the charging permission condition information associated with the received ID is satisfied at that time. Is determined by referring to (second authentication step).

  When the charging permission condition includes a time period for permitting charging, the authentication unit 31 refers to the timer 5, acquires time information indicating the current time, and is recorded in the management table 61. It is determined whether or not the current time is included in a certain time zone.

  When the upper limit value of the charge amount to the storage battery 42 is defined, the authentication unit 31 acquires charge amount information indicating the charge amount of the storage battery 42 from the storage battery management unit 23, and the charge indicated by the charge amount information. It is determined whether the amount is larger than the upper limit value of the charge amount recorded in the management table 61.

  If it is determined that the charging permission condition is satisfied (for example, the time at that time is included in the time zone in which charging is permitted) (YES in S5), authentication unit 31 indicates that charging is instructed. A charge command is output to the charge / discharge control unit 32.

  Upon receiving the charge command, the charge / discharge control unit 32 controls the power conversion device 11 to start charging with the charge setting indicated by the charge setting information corresponding to the ID recorded in the management table 61 (S6). ). That is, the charge / discharge control unit 32 controls the power conversion apparatus 11 so that a direct current of the set power (W) flows from the house power management system 1 to the storage battery 42.

  In addition, when the charging permission condition information is not associated with the received ID, the authentication unit 31 starts charging when the IDs match. If the charging setting information is not associated with the received ID, the user may specify arbitrary power via the input unit 8. At this time, the input setting may be automatically recorded in the management table 61 as charge setting information. With this configuration, it is possible to save the trouble of specifying power when the electric vehicle 20 with the ID is charged next time.

  When the charge permission condition information includes the upper limit value of the charge amount to the storage battery 42, the authentication unit 31 continuously transmits the charge amount information from the storage battery management unit 23 after charging of the storage battery 42 is started. And monitoring whether the charge amount to the storage battery 42 does not exceed the upper limit value indicated by the charge permission condition information.

  If it determines with the charge amount to the storage battery 42 having reached the regulation value (upper limit value) (it is YES at S7), the authentication part 31 will output the charge stop command which stops charge to the charge / discharge control part 32. FIG.

  When this charge stop command is received, the charge / discharge control unit 32 controls the power converter 11 to stop charging. For example, the charge / discharge control unit 32 controls the power converter 11 so as to disconnect the electrical connection between the storage battery 42 and the in-house device 13.

  When the charging permission condition includes a time zone in which charging is permitted, the authentication unit 31 refers to the timer 5 and outputs a charge stop command when the charging time is out of the charging time zone. Output to. The charge amount and time zone of the storage battery 42 may be managed by the charge / discharge control unit 32.

  On the other hand, when determining that the charging permission condition is not satisfied (NO in S5), authentication unit 31 ends the process without starting charging.

  If there is no matching ID in S4 (NO in S4), authentication unit 31 ends the process without permitting charging. However, even if there is no matching ID, the authentication unit 31 may be realized by a configuration that proceeds to the step of S5.

(Effect of charge / discharge system 100)
In the charging / discharging system 100, even if the electric vehicle 20 has an ID not registered in the management table 61, the authentication unit 31 determines to permit charging of the storage battery when the condition indicated by the permission condition information is satisfied. It can be performed. Therefore, for example, when the customer's electric vehicle 20 whose ID is not registered is not in an emergency, that is, the electric vehicle 20 can be charged even in a normal time, thereby increasing customer satisfaction. Can do. That is, in the charging / discharging system 100, even if the IDs do not match, charging that reflects the intention of the user of the electric vehicle 20 (or the home power management system 1) can be realized.

(Example of changing the management table 61)
For example, in the management table 61 shown in FIG. 2, the ID of the electric vehicle 20 that permits charging is registered, but the ID of the electric vehicle 20 that does not allow charging may be registered. In this case, the authentication unit 31 determines not to permit charging from the storage battery 42 when the acquired ID of the electric vehicle 20 matches the ID registered in the management table 61 in advance.

  Further, the charging permission condition information and the charging setting information may be stored in association with the ID of the electric vehicle 20 in the storage unit 24 of the electric vehicle 20 instead of the storage unit 6 of the house power management device 2. In this case, only the ID of the electric vehicle 20 that may be allowed to be charged is registered in the management table 61 of the house power management device 2. The flow of processing in this configuration will be described.

  FIG. 4 is a flowchart showing another example of the process flow in the house power management system 1. Since S11 to S14 in FIG. 4 are the same as S1 to S4 in FIG. 3, the description thereof is omitted.

  If there is a matching ID in S14 (YES in S14), authentication unit 31 transmits a permission condition request signal instructing transmission of charging permission condition information to control unit 22 of electric vehicle 20 (S15). .

  When receiving the permission condition request signal, the control unit 22 transmits the charging permission condition information stored in the storage unit 24 to the house power management apparatus 2.

  When the charging permission condition information is received (S16), the authentication unit 31 determines whether or not the charging permission condition indicated by the charging permission condition information is satisfied at that time. The charging permission condition information may include charging non-permission information indicating that charging is not permitted. In this case, the authentication unit 31 determines that the charging permission condition is not satisfied.

  If it is determined that the charging permission condition is satisfied (YES in S17), authentication unit 31 outputs a charging command indicating that charging is instructed to charging / discharging control unit 32.

  When the charge command is received, the charge / discharge control unit 32 controls the power converter 11 to start charging with the charge setting indicated by the received charge setting information (S18).

  In addition, when charging permission condition information is not matched with respect to received ID, the charge / discharge control part 32 will start charge, if ID corresponds. If the charging setting information is not associated with the received ID, the user may specify arbitrary power via the input unit 8.

  When the upper limit value of the charge amount to the storage battery 42 is included in the charge permission condition information, the authentication unit 31 refers to the charge amount information continuously transmitted from the storage battery management unit 23 after starting the charge, It is monitored whether the amount of charge to the storage battery 42 has reached the upper limit.

  If it is determined that the amount of charge to storage battery 42 has reached the upper limit (YES in S19), authentication unit 31 outputs a charge stop command to charge / discharge control unit 32.

  On the other hand, if it is determined that the charging permission condition is not satisfied (NO in S17), authentication unit 31 ends the process without starting charging.

  Note that the charge permission condition information and the charge setting information recorded in the storage unit 24 of the electric vehicle 20 can be rewritten by the user of the electric vehicle 20, and an input unit therefor is provided in the vehicle power management device 21. Good.

  Further, even when there is no matching ID in S14, the authentication unit 31 may be realized by a configuration that proceeds to the step of S15.
