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.
