<P>PROBLEM TO BE SOLVED: To provide a charge-discharge system including an electric storage section, which can be charged with an electric power from an external power supply and can be discharged by supplying an electric power to an external electric load. <P>SOLUTION: The charge-discharge system includes a vehicle 10, an electric power cable 20, a plug-in station 30, an HEMS (Home Energy Management System) 40, and a commercial power supply 50. A request for charging to charge an electric storage device 11 and a request for discharging to allow an external electric load to use the electric power of the electric storage device 11 are transmitted from the HEMS 40 to the vehicle 10, through PLC (Power Line Communication). When a request is changed from the request for charging to the request for discharging, or vice versa, the vehicle 10 does not immediately change the operations from a charging operation to a discharging operation or vice versa but establishes a charge-discharge stop state in which neither the charging operation nor the discharging operation is carried out. <P>COPYRIGHT: (C)2013,JPO&INPIT |
