A vehicle 10 according to an embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. In a state where the connector 21 of the electric power cable 20 is connected with the inlet of the vehicle 10, an electric power is discharged/supplied from the vehicle electric storage device 11 to an external electric load (e.g., external electric storage device 41). Further, the vehicle electric storage device 11 is capable of being charged by the external power supply 50 through the electric power cable 20. A control device 12 of the vehicle 10 obtains/detects a permissible current value of the electric power cable 20, based on a specific signal (control pilot signal) which is transmitted through a CPLT terminal of the connector 21 before it starts the discharge to the external electric load from the vehicle electric storage device 11.

摘要:
A vehicle 10 according to the embodiment of the present invention is applied to a charge-discharge system CDS. The charge-discharge system includes the vehicle 10, an electric power cable 20, a plug-in station 30, a HEMS 40, and a commercial power supply 50. From the HEMS 40 to the vehicle 10, a request for charge to charge an electric storage device 11 and a request for discharge to allow an external electric load to use an electric power of the electric storage device 11 are transmitted. When a request is changed from the request for charge to the request for discharge, or vice versa, the vehicle 10 realizes a charge-discharge stop state in which neither a charging operation nor a discharging operation is performed without directly changing from the charging operation to the discharging operation, or vice versa.
