Abstract

The invention discloses a safety control device of an electric vehicle. A high-voltage battery control module cuts off a first control end of a high-voltage relay and/or a whole vehicle control module cuts off a second control end of the high-voltage relay through an emergency power-off module to make the high-voltage relay cut off, and thus a high-voltage power supply loop of all components of the whole vehicle is cut off. The invention further discloses a safety control method of the electric vehicle. By means of the safety control method and device of the electric vehicle, the high-voltage electricity of the whole vehicle can be effectively cut off in time when a collision occurs, and thus electric shock of people can be avoided; when a slight collision occurs or no electric leakage risk exists, the dynamic property of the whole vehicle can be maintained, and thus the vehicle can quickly leave a dangerous area; the structure is simplified, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to the field of electric vehicle control, in particular to a safety control method and device for an electric vehicle. Background technique [0002] With the increasingly serious problems of environmental degradation, greenhouse effect and energy depletion, people are paying more and more attention to the development of new energy. And people's daily transportation is indispensable to cars. Under this background, electric vehicles are getting more and more attention. [0003] With the widespread use and popularization of electric vehicles, there have been occasional news reports that electric vehicles caught fire due to collisions, electric shocks and even casualties occurred. This has caused people's panic, and it also reflects people's higher and more reliable protection requirements for the safety of electric vehicles. [0004] In the prior art, there are a considerable number of electric vehicle collision incidents. After th...
