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.

A vehicle is capable of charging a power storage device mounted thereon using electric power from two power paths of an external DC power supply and AC power supply. The vehicle includes a DC charger for converting electric power from the DC power supply into charging electric power for the power storage device, and an AC charger for converting electric power from the AC power supply into charging electric power for the power storage device. A vehicle ECU selects an electric power path to be used for charging based on the state of the power storage device and efficiency of the DC charger and the AC charger.

A contactless power feeding system includes a power transmitting device including a power transmitting unit and a power receiving device including a power receiving unit, and allows the power transmitting and receiving units to electromagnetically resonate with each other to supply electric power contactlessly. The power receiving device includes a power storage device for storing therein the electric power received by the power receiving unit, and a light emitting unit receiving the electric power received by the power receiving unit and emitting light, and varying in brightness according to the electric power received. The received electric power varies according to a positional displacement between the power transmitting unit and the power receiving unit. The user can recognize the positional displacement from information relevant to the brightness of the light emitting unit.

In a cable connection structure in which a roughly spherical cable end disposed at the tip of an inner wire is connected to a movable member, the movable member is provided with a pair of wing pieces that hold the inner wire, a cable insertion opening that guides the cable end to a space between the wing pieces, and a roughly elliptical cable end passage part that displaceably supports the cable end. The long axis of the roughly elliptical shape of the cable end passage part roughly coincides with the direction of insertion of the cable.

A vehicle has a low voltage power generating unit mounted thereon, which passively generates low voltage power when the vehicle is electrically connected to commercial power supply through coupling of a connector unit. A winding transformer transforms the commercial power supply input to the primary side with a prescribed ratio of transformation, and the transformation is performed without requiring any control signal from the outside. The AC power with voltage lowered, output from the secondary side of winding transformer, is rectified by a diode unit, and a low voltage power is generated. The low voltage power generated by the diode unit is supplied through a supplementary low voltage DC line to a sub battery and to a controller.

An electric power supply device generates electric power having a prescribed frequency. An electric power transfer unit receives electric power from the electric power supply device, and transfers electric power to an electric power receiving unit in a contactless manner by resonating with the electric power receiving unit via an electromagnetic field. An electric power sensor senses power reflected to the electric power supply device. A discharging coil unit externally discharges electric power output from the electric power supply device. A relay electrically connects the discharging coil unit between the electric power supply device and the electric power transfer unit when the reflected power detected has a value exceeding a predetermined value.
