Abstract

The invention discloses a circuit protection device and method for an electric vehicle. The device includes a power battery contactor state acquisition unit configured to acquire the on / off state of apower battery contactor; an assembly main contactor state acquisition unit configured to acquire the on / off state of an assembly main contactor; and an assembly main contactor state locking unit configured to lock the assembly main contactor to an on state when the power battery contactor is turned off. The device of the present invention can lock the power battery contactor and the assembly maincontactor of the electric vehicle in an associated way, thereby preventing a driver's traditional fuel vehicle driving habit from causing the pure electric vehicle to work abnormally. Compared to theprior art, the device of the present invention is simple in structure and easy to implement, can greatly improve the safety and the stability of the pure electric vehicle, and has a high practical value and a promotion value.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a circuit protection device and method for electric vehicles. Background technique [0002] With the continuous development of electric vehicle technology, electric vehicles are more and more used in the daily production and life of human beings. [0003] Since traditional fuel vehicles still play a dominant role, in order to unify vehicle structure and driving mode, in the prior art, many control modes of pure electric vehicles are set with reference to traditional fuel vehicles. For example, the key signal of a pure electric vehicle simulates a traditional fuel vehicle, and is also divided into OFF gear, ACC low-voltage gear, and ON start gear. [0004] At the same time, since the driving habits of drivers are mostly cultivated by traditional fuel vehicles, some drivers still drive according to the driving habits of fuel vehicles for emerging products such as pure electric...
