POWER FEED SYSTEM FOR ELECTRIC VEHICLE

摘要

A control device 3 is configured to generate a switching signal for changing the operation of the bidirectional power feeding device 2 to either a charging operation or a feeding operation based on both power supplied from a DC power supply and power required for a distribution circuit 10 side. A bidirectional power feeding device 2 comprises: a control part 23 configured, based on the switching signal, to make the electric vehicle 60 change its operation to either a charging operation for charging the battery 62 or a feeding operation for supplying the DC distribution board 1 with DC power discharged from the battery 62; a DC-DC converter 21 configured to convert the voltage value of DC power from the DC distribution board 1 and to supply to the battery 62 of the electric vehicle 60; and a DC-DC converter 22 configured to convert the voltage value of DC power from the battery 62 of the electric vehicle 60 to supply to the DC distribution board 1.
