Electric powered vehicle, vehicle charge device and vehicle charge system
First Claim
1. An electric powered vehicle, mounting a rechargeable first power storage unit and allowing charging of said first power storage unit by an external power supply, comprising:
- a connector receiving portion coupled at the time of charging to a connector unit outside of the vehicle, for receiving electric power from said external power supply;
a power converting unit for converting the electric power from said external power supply, supplied by the coupling of said connector unit and said connector receiving portion and for charging said first power storage unit;
a rechargeable second power storage unit having lower output voltage than said first power storage unit;
a control unit operating with electric power from said second power storage unit and for controlling power converting operation of said power converting unit; and
a low voltage charging unit for charging said second power storage unit,wherein the coupling of said connector unit and said connector receiving portion directly connects the external power source to the low voltage charging unit, which is directly connected to the second power storage unit and control unit, andwherein the low voltage charging unit for charging the second power storage unit is independent of state of operation of the control unit, when the connector unit is coupled to the connector receiving portion.

Abstract
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.
