<P>PROBLEM TO BE SOLVED: To provide a power supply system capable of stabilizing discharge power when discharging electric power from a storage battery mounted in a vehicle to an AC power line in a building without providing a new complex device. <P>SOLUTION: A control ECU 30, when charging an onboard storage battery, supplies AC power of an AC power line 4 via a charge power line 21 to a discharge and charge connector 23. The control ECU 30, when discharging from the onboard storage battery, if the AC power is output from a vehicle 90 to the discharge and charge connector 23, transfers the power via an AC discharge power line 31 to a power storage unit 10 to be converted into DC power by a power converter 13 and discharged via a bidirectional power conditioner 11 to the AC power line 4. If the DC power is output from the vehicle 90 to a discharge connector 223, the power is transferred via a DC discharge power line 231 to the power storage unit 10 to be discharged via the bidirectional power conditioner 11 to the AC power line 4. <P>COPYRIGHT: (C)2012,JPO&INPIT |
