ADAPTER AND VEHICLE FOR PERFORMING POWER FEEDING USING ADAPTER
First Claim
1. An adapter used for supplying electric power from a power source including a power storage device mounted in a vehicle to an electrical device external to the vehicle through a charging cable, the vehicle being capable of performing external charging that allows the power storage device to be charged using electric power supplied from an external power supply through the charging cable,in response to a signal instructing power feeding that is generated by connection between the adapter and the charging cable, the vehicle performing power feeding to the electrical device,the adapter comprising:
- a first connection unit capable of connecting a power supply plug connected to the external power supply in the charging cable during external charging;
a second connection unit electrically connected to the first connection unit and capable of connecting a power supply plug of the electrical device; and
a leakage generation circuit causing a leakage state in a power transmission path connecting the first connection unit and the second connection unit when the adapter and the charging cable are incompletely fitted to each other.

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.

9. A vehicle capable of performing external charging that allows a power storage device mounted therein to be charged using electric power supplied from an external power supply through a charging cable and capable of feeding electric power to an external electrical device by connection of an adapter to the charging cable, the vehicle comprising:
-
a power source including the power storage device; an inlet for connecting the charging cable during external charging; a power conversion device for converting electric power from the power source to supply the converted electric power to the inlet; and a control device for controlling the power conversion device, the adapter including a first connection unit capable of connecting a power supply plug connected to the external power supply in the charging cable during external charging, a second connection unit electrically connected to the first connection unit and capable of connecting a power supply plug of the electrical device, and a leakage generation circuit causing a leakage state to occur in a power transmission path connecting the first connection unit and the second connection unit when the adapter and the charging cable are incompletely fitted to each other, in response to reception of a signal instructing power feeding that is generated by connection between the adapter and the charging cable, the control device driving the power conversion device to supply the electric power from the power source to the electrical device, and the control device stopping power feeding to the electrical device when the leakage state is detected.
