Emergency Startup Device of Electric Vehicle
First Claim
1. An emergency startup device of an electric vehicle, comprising:
- a high-voltage power battery;
a motor driver, driving a power motor;
a high-voltage control box, comprisingan input port electronically connected to the high-voltage power battery; and
an output port electronically connected to the motor driver;
a vehicle controller, electronically connected to the high-voltage control box to turn on or turn off the high-voltage control box;
wherein when the high-voltage control box is turned on, the high-voltage power battery provides electricity to the motor driver through the high-voltage control box, and the motor driver drives the power motor;
a low-voltage DC battery;
a DC-to-DC converter, electronically connected between the low-voltage DC battery and the output port of the high-voltage control box;
wherein when the high-voltage control box is turned on, the high-voltage power battery further provides the electricity to charge the low-voltage DC battery through the DC-to-DC converter to charge the low voltage DC battery;
a startup switch, electronically connected between the low-voltage DC battery and the vehicle controller;
wherein when the startup switch is turned on, the low-voltage DC battery provides electricity to the vehicle controller through the startup switch;
an emergency starter, comprising;
a switch module, electronically connected between the high-voltage power battery and the DC-to-DC converter; and
a switch control module, electronically connected to the switch module to turn on or turn off the switch module;
wherein when the switch module is turned on, the high-voltage power battery is electrically connected to the DC-to-DC converter through the switch module to charge the low-voltage DC battery through the DC-to-DC converter.

Abstract
An emergency startup device of an electric vehicle has a high-voltage power battery, a motor driver, a high-voltage control box, a vehicle controller, a low-voltage DC battery, and an emergency starter. The vehicle controller turns on or off the high-voltage control box. When the low-voltage DC battery does not have enough electricity to provide electricity to the vehicle controller, the vehicle controller may not turn on the high-voltage control box, the high-voltage power battery may not provide electricity to the motor driver, and the electric vehicle may not be driven. When the emergency starter is operated, the high-voltage power battery charges the low-voltage DC battery through the emergency starter. Then, the low-voltage DC battery provides enough electricity to the vehicle controller, and the electric vehicle is normally driven.
