Abstract

An ECU performs processing including: a step of obtaining a pilot signal CPLT and a connector connection signal PISW; a step of determining, when a connector is attached, a type of the connector; a step of controlling, when there is a function corresponding to the type of the attached connector, the connector to be set to a lock state; a step of performing control corresponding to the attached connector; and a step of maintaining, when there is no function corresponding to the type of the attached connector, an unlock state of the connector.

First claim

What is claimed is:

1 . An electrically powered vehicle comprising:
a power storage device; an inlet to which a connector of an external facility external to the vehicle can be attached; a lock mechanism that locks the connector in the inlet; and an electronic control unit configured to control the lock mechanism between a lock state and an unlock state, in the lock state the connector is restricted from being removed from the inlet, and in the unlock state the connector is permitted from being removed from the inlet, wherein:
the electronic control unit is configured to control the lock mechanism into the lock state to lock the connector to the inlet in response to detecting attachment of the connector to the inlet;
the electronic control unit is configured to:
determine whether a type of the connector is included in a list of types of available connectors stored in a memory of the electronic control unit prior to exchanging power between the connector and the power storage device of the electrically powered vehicle; and
control the lock mechanism into the lock state and maintain the lock mechanism in the lock state to lock the connector to the inlet in response to determining that the type of the connector is included in the list of types of available connectors stored in the memory, and

the electrically powered vehicle is configured to receive at least one of information about a maximum limit value of a current, information about a minimum limit value of the current, information about a maximum limit value of a voltage, and information about a minimum limit value of the voltage from the external facility.

2 . The electrically powered vehicle according to claim 1 , wherein:
the electronic control unit is configured to control the lock mechanism into the lock state to lock the connect to the inlet in response to detecting attachment of the connector to the inlet based on a pilot signal and a connector connection signal, and when the connector is plugged into the inlet, a potential of the pilot signal changes from a first state to a second state.
