Abstract

An electrically powered vehicle is connected to an external power supply through a charge plug. A relay is interposed in an electrical path extending to a power storage device from a power feed node electrically connected to the external power supply through the charge plug. A control device operates with electric power from an auxiliary machinery power supply provided separately from the power storage device and controls opening and closing of the relay in correspondence with a period during which the power storage device is charged. None of electric power consuming components mounted on the electrically powered vehicle is connected to the power feed node. Therefore, even during a period in which the electrically powered vehicle is connected to the external power supply, all electric power consuming components can electrically be disconnected from the external power supply by turning off the relay.

Claims13

Dependent claims

An electrically powered vehicle that can be charged by an external power supply, comprising:

a power feed node electrically connected to said external power supply through a connection device;
a power storage device for storing electric power to be used for generating vehicle drive force, configured such that it can be charged with electric power supplied by said external power supply;
a switching element interposed in an electrical path from said power feed node to said power storage device;
and
a control device operating by using electric power from an auxiliary power storage device provided separately from said power storage device, for controlling opening and closing of said switching element in correspondence with a period during which said power storage device is charged, and
all electric power consuming components mounted on said electrically powered vehicle being arranged to electrically be disconnected from said power feed node, as a result of opening of said switching element.
