Electric vehicle
First Claim
1. An electric vehicle comprising:
- a high-voltage power source at least including a first power source;
a low-voltage battery that is supplied with electric power from the high-voltage power source through a converter;
an auxiliary vehicle controller for controlling a high-voltage contactor with electric power supplied from the high-voltage power source through the converter or with electric power supplied from the low-voltage battery; and
an electric motor driving with electric power supplied from the high-voltage power source,the high-voltage contactor being connectedly provided between the high-voltage power source and the auxiliary vehicle controller,the auxiliary vehicle controller controlling the high-voltage contactor in such a manner that the electric power supply from the high-voltage power source is shut off if the electric power supply from the low-voltage battery to the auxiliary vehicle controller is cut off.

Abstract
The present invention provides an electric vehicle including a high-voltage power source at least including a first power source; a low-voltage battery that is supplied with electric power from the high-voltage power source through a converter; an auxiliary vehicle controller for controlling a high-voltage contactor with electric power supplied from the high-voltage power source through the converter and/or with electric power supplied from the low-voltage; and an electric motor driving with electric power supplied from the high-voltage power source. The high-voltage contactor is connectedly provided between the high-voltage power source and the auxiliary vehicle controller, and the auxiliary vehicle controller controls the high-voltage contactor in such a manner that the electric power supply from the high-voltage power source is shut off if the electric power supply from the low-voltage battery to the auxiliary vehicle controller is cut off.
