A charging system includes a locking device locking a connector provided at the end of a cable in the state where the connector is connected to an inlet provided in a vehicle; a release button for releasing locking by the locking device; a switch generating a signal indicating that the connector and the inlet are connected; a horn; and an ECU. In response to the operation of the release button, the switch stops generation of the signal. The ECU controls charging of a power storage device and detects whether the signal is issued or not. In the case where the ECU detects that generation of the signal is stopped during charging of the power storage device, the ECU causes the horn to issue an alarm.

Charging system

Power feeding is performed in a non-contact manner from a power feeding device to an electrical powered vehicle by resonance of a primary self-resonant coil of the power feeding device and a secondary self-resonant coil of the electrical powered vehicle through an electromagnetic field. The electric power received by the secondary self-resonant coil is rectified by a rectifier, and voltage-converted by a DC/DC converter to be supplied to a power storage device. A vehicle ECU controls the DC/DC converter such that the voltage between the rectifier and the DC/DC converter attains a target voltage.

Power feeding system and electrical powered vehicle

In a charging system for a vehicle for charging a power storage device, including the vehicle having the power storage device, and a charging cable for transmitting electric power supplied from an external power supply outside of the vehicle to the power storage device, charging information about charging performed by a charging device is set based on a signal generated by operation of an operation switch provided on a charging connector. This configuration can improve operability during charging.

Vehicle, charging cable, and charging system for vehicle

In a noncontact electric power feeding system using a resonance method, electrical equipment installed within a coil case is configured to include an electric power receiving antenna and a rectifier in an integrated manner. The electrical equipment is driven by receiving electric power from an electromagnetic field generated by electromagnetic resonance, without power supply from the outside of the coil case.

Noncontact electric power receiving device, noncontact electric power transmitting device, noncontact electric power feeding system, and vehicle

A conversion adaptor enables utilization of a standardized charge cable used when a power storage device mounted on an electrically-powered vehicle is charged by a power source provided outside of the vehicle as a universal cable for transmitting electric power to electric loads having different plug shapes that are respectively standardized from one region to another. Conversion adaptor includes a primary side connector unit configured to be connectable to a connector of charge cable, a secondary side connector unit configured so as to have a plug of an electric load, such as a home electric appliance, connected thereto, and a manipulating unit for manipulating a CCID of charge cable so that relays are switched off when connector of charge cable is connected to first connector unit.
