Abstract

The invention relates to a high-voltage safety control system of an electric vehicle. The high-voltage safety control system comprises a power module, a power distribution module, a safety monitor and control module, a vehicle control unit, a motor controller and a motor, wherein the power module is used for supplying power for the electric vehicle, the power distribution module is used for controlling on-off of a high-voltage circuit through a high-voltage relay, the safety monitor and control module is used for monitoring high-voltage electricity consumption information of the electric vehicle and transmitting the high-voltage electricity consumption information to the vehicle control unit, the vehicle control unit is used for receiving the high-voltage electricity consumption information through a high-voltage power-up and power-down management module and controlling on and off of the high-voltage relay in the power distribution module according to the high-voltage electricity consumption information. A safe control system is established for the electric vehicle, various safety protection functions are comprehensively and systematically realized, the control method is more reasonable, the whole vehicle and the personal safety of drivers can be effectively protected, and relatively high operability is realized.

Description

technical field [0001] The invention relates to a safety control system, in particular to a high-voltage safety control system of an electric vehicle. Background technique [0002] High-voltage safety is the most concerned issue in the electric vehicle industry. The safety control of the high-voltage system includes not only ensuring the transmission of power and electric energy in the vehicle system, but also monitoring the insulation faults, open circuit faults, and grounding faults of the other high-voltage systems at any time to ensure the safety of the entire vehicle system. Vehicle equipment and driver safety. In the prior art, the insulation monitoring method is usually used to monitor whether the electric vehicle is leaking electricity; the high-voltage interlock method is used to protect the safety of personnel under abnormal power failures such as hot plugging and unplugging of high-voltage connectors; the method of pre-charging circuit is used to protect motors co...
