The processing device 1 detects the voltage of the secondary battery 4 as residual power under the control of the battery detection unit 10a of the control unit 10, and determines whether charging is necessary from the detected residual power (S101).

  If it is determined in step S101 that charging is required (S101: YES), the processing device 1 detects the type of the secondary battery 4 accommodated in the accommodation unit 12 under the control of the battery detection unit 10a of the control unit 10. Then, it is determined whether or not the detected type of the secondary battery 4 is compatible with quick charging (S103). In step S103, it is determined whether or not the secondary battery 4 accommodated in the accommodating portion 12 is the quick charge compatible secondary battery 4b. When it is determined in step S101 that charging is not required (S101: NO), the processing device 1 executes the process of step S101 again after a predetermined time has elapsed.

  In Step S103, when it is determined that the type of the secondary battery 4 is the quick charge compatible secondary battery 4b that supports rapid charging (S103: YES), the processing device 1 detects the contact / separation detecting means of the control unit 10. Under the control of 10b, the contact / separation state of the rapid power feeding device 3 with respect to the second connection portion 15b is detected (S104), and it is determined whether the rapid power feeding device 3 is connected to the second connection portion 15b from the detected contact / separation state. Determination is made (S105).

  If it is determined in step S105 that the rapid power feeding device 3 is connected to the second connection unit 15b (S105: YES), the processing device 1 starts rapid charging under the control of the charging control unit 10c of the control unit 10.

It is determined whether at least one of 2 and the rapid power feeding device 3 is connected (S110).

  In step S110, when it is determined that at least one of the normal power supply device 2 and the rapid power supply device 3 is connected (S110: YES), the processing device 1 performs normal charging under the control of the charge control unit 10c of the control unit 10. The control unit 17 is caused to start normal charging (S111). When the normal charging control unit 17 starts the charging control related to the normal charging, the charging by the power feeding from the normal power feeding device 2 or the quick power feeding device 3 is started.

  The processing device 1 detects the voltage of the secondary battery 4 under the control of the battery detection unit 10a of the control unit 10, and determines whether or not a predetermined amount of charging has been completed (S112).

The contact / separation state of the normal power supply device 2 with respect to the unit 15a is detected (S114), and it is determined from the detected contact / separation state whether the normal power supply device 2 is connected (S115).

  If it is determined in step S115 that the normal power supply device 2 is connected (S115: YES), the process proceeds to step S111, and the processing device 1 controls the normal charge control unit 17 under the control of the charge control means 10c of the control unit 10. The normal charging is started (S111). When the normal charging control unit 17 starts charging control related to normal charging, charging by power feeding from the normal power feeding device 2 is started.

  If it is determined in step S110 that neither the normal power supply device 2 nor the rapid power supply device 3 is connected (S110: NO), the processing device 1 proceeds to step S101 and repeats the subsequent processing. In this way, the processing device 1 executes processing related to charging.

During this time, power is always supplied from the normal charging power supply circuit 30. Then, the quick power supply device 3 determines whether or not a quick charge start command, which is a control command for starting the quick charge, is received from the processing device 1 under the control of the quick charge control unit 33 (S201). The quick charge start command to be determined in step S201 is a control command transmitted from the processing device 1 to the rapid power feeding device 3 in the process of step S106 shown using FIG.

  When it is determined in step S201 that a quick charge start command has been received (S201: YES), the quick power supply device 3 controls the power supply and charge from the quick charge power supply circuit 31 under the control of the quick charge control unit 33.

It is determined whether a quick charge end command has been received (S205). The quick charge end command to be determined in step S205 is a control command transmitted from the processing device 1 to the quick power feeding device 3 in the processing of step S108 shown in FIG.

  If it is determined in step S205 that a quick charge end command has been received (S205: YES), the quick power supply device 3 ends the power supply and charge control from the quick charge power supply circuit 31 under the control of the quick charge control unit 33.

The power feeding and charging control from the power feeding circuit 31 is terminated (S206), the process proceeds to step S201, and the subsequent processing is repeated. Even when the rapid power feeding device 3 is detached at the time of rapid power feeding that outputs a large current, the power feeding is automatically terminated to provide a disaster prevention effect such as prevention of electric shock.

  If it is determined in step S205 that a quick charge end command has not been received (S205: NO), the rapid power supply apparatus 3 proceeds to step S203 under the control of the rapid charge control unit 33 and repeats the subsequent processing. In this way, the rapid power feeding device 3 executes processing related to rapid charging.
