Abstract
An adapter includes a signal generation unit and a leakage generation circuit. The signal generation unit provides a signal instructing power feeding to a vehicle when the adapter is connected to a plug of a charging cable used for external charging with electric power from an external power supply. When the plug and the adapter are not completely fitted to each other, the leakage generation circuit electrically connects the power transmission path to a ground to cause a leakage state. In the vehicle, in response to a signal instructing power feeding, a power conversion device is driven to supply electric power from the vehicle to an external electrical device through the charging cable. Then, when the leakage state is caused by the leakage generation circuit, power feeding to the electrical device is stopped.
