On the other hand, if the measured value of the backflow voltage is not 0V, the process proceeds to the 21st step S21.

  In the thirteenth step S13, the EV-ECU 56 determines whether the detection result by the IG position sensor 81 is the OFF position, the ACC-ON position, or any other position. When the detection result is the OFF position or the ACC-ON position, the process proceeds to the 14th step S14. If the detection result is neither the OFF position nor the ACC-ON position, the process proceeds to the 21st step S21.

  In the fourteenth step S14, the EV-ECU 56 determines whether or not the value detected by the shift sensor 82 is a parking position (parking range). When the detected value is a parking position, the process proceeds to a fifteenth step S15. If the detected value is other than the parking position, the process proceeds to the 21st step S21.

  In the fifteenth step S15, the EV-ECU 56 determines whether or not the value detected by the brake sensor 83 is the brake ON position. If the detected value is the brake ON position, the process proceeds to a sixteenth step S16. If the detected value is other than the brake ON position, the process proceeds to the 21st step S21.

  In the sixteenth step S16, the EV-ECU 56 determines whether or not the battery remaining amount SOC of the EV driving battery 51 by the voltage measuring device 84 is 30% or more. When the remaining battery SOC of the EV drive battery 51 is 30% or more, the process proceeds to the 17th step S17. When the remaining battery SOC of the EV drive battery 51 is less than 30%, the process proceeds to the 21st step S21. Thereby, the electric power required for starting the electric vehicle 50 is ensured.

  In the 21st step S <b> 21, the interface 19 and the EV-ECU 56 stop activation of the portable power supply device 10. The interface 19 transmits a stop signal for stopping the operation of the DC / AC inverter 14 to the DC / AC inverter 14. Thereby, starting of the DC / AC inverter 14 is stopped. The EV-ECU 56 transmits a signal to the quick charge contactor 52. Thereby, the quick charge contactor 52 forms an open circuit between the EV drive battery 51 and the quick charge connector 53. That is, the start-up of the portable power supply device 10 is stopped, while the power transmission from the electric vehicle 50 to the portable power supply device 10 is stopped.

Form. As a result, the electric power stored in the EV drive battery 51 is supplied to the portable power supply device 10 via the quick charge contactor 52 and the quick charge connector 53. That is, DC 330V power is transmitted from the electric vehicle 50 to the portable power supply device 10 (18th step S18).

  Subsequently, in 19th step S19, the DC 330V power transmitted to the portable power supply device 10 is converted into AC 100V power by the DC / AC inverter 14. As a result, AC 100 V can be supplied from the AC 100 V outlet 15 of the portable power supply device 10 to the outside.

  That is, if the authentication code of the keyless operation key 46 and the authentication code of the portable power supply device 10 match and then the authentication code of the keyless operation key 46 and the authentication code of the electric vehicle 50 match, the EV-ECU 56 The charging contactor control unit controls the quick charging contactor 52 to form a closed circuit between the EV driving battery 51 and the quick charging connector 53 and transmit electric power from the electric vehicle 50 to the portable power supply device 10. Can do. Further, the interface 19 can start the DC / AC inverter 14. As a result, the portable power supply device 10 is in a state in which AC100V can be supplied to the outside via the AC100V outlet 15. On the other hand, when the predetermined condition is not satisfied, for example, when the authentication code of the keyless operation key 46 does not match the authentication code of the electric vehicle 50, the quick charge contactor control unit of the EV-ECU 56 controls the quick charge contactor 52. Thus, an open circuit is formed between the EV drive battery 51 and the quick charge connector, and power transmission from the electric vehicle 50 to the portable power supply device 10 is stopped. Further, the interface 19 stops the activation of the DC / AC inverter 14.
