Electric vehicle
First Claim
1. An electric vehicle comprising:
- a motor inverter that supplies electric power to a wheel-driving motor, the motor inverter having a smoothing capacitor;
a pump that delivers a cooling medium to at least one of the motor inverter and the wheel-driving motor;
a storage capacitor that stores a counter electromotive force generated by the pump;
a pump inverter that supplies electric power to the pump to drives the pump; and
a controller that is configured to stop a supply of electric power from the pump inverter to the pump and connect the pump inverter to the storage capacitor when the controller receives a signal indicating a collision of the vehicle.

Abstract
An electric vehicle includes a wheel-driving motor, a motor inverter that supplies electric power to the wheel-driving motor, a pump that delivers a cooling medium to at least one of the motor inverter and the motor, a capacitor that stores a counter electromotive force generated by the pump, and a pump inverter that supplies electric power to the pump to drives the pump. When a vehicle controller receives a signal indicating a collision of the vehicle, the vehicle controller stops a supply of electric power from the pump inverter to the pump and connects the pump inverter to the capacitor. The pump inverter converts AC power generated by the counter electromotive force of the pump into DC power to store the DC power in the capacitor.
