Abstract

The invention provides a vehicle safety device. The device comprises a battery pack, a pre-charging module and a charging module. The battery pack comprises a plurality of battery modules, and a fuse is in series connection between every two adjacent battery modules. The pre-charging module is connected with the positive-pole end of the adjacent battery module, a vehicle inverter, an electric air conditioner controller, a direct-current chopper and a motor controller, and is used for performing pre-charging protection on the inverter, the electric air conditioner controller, the direct-current chopper and the motor controller when the inverter, a vehicle control unit and a battery management system are in a normal state. The charging module is connected with the vehicle control unit, the battery management system and a radiator of the battery pack, and is used for controlling start and stop of the radiator according to temperature information of the radiator when the battery management system controls charging of the battery pack. By the vehicle safety device, the standardization of vehicle safety circuit design can be enhanced to the greatest extent, and senses of trust and security of people on new energy automobiles are improved.

Description

technical field [0001] The invention relates to the technical field of vehicle engineering, in particular to a vehicle safety device. Background technique [0002] Under the pressure of the energy crisis and environmental protection, and with the promotion of governments at all levels, new energy vehicles have achieved rapid development in recent years, but there have also been some safety hazards and safety accidents, such as the electric taxi burning incident in Hangzhou, The burning of electric buses in Shanghai and the explosion of electric taxis in Shenzhen have raised doubts about the safety of new energy vehicles. Although designers of high-voltage circuits for new energy vehicles have considered their safety at the beginning of product development, such as leakage detection, high-voltage insulation, pre-charge protection, over-current and over-voltage protection, battery charging protection, fault alarm and connector error prevention wait. However, the processing o...
