Description
technical field [0001] The invention relates to the technical field of energy feedback of pure electric vehicles, in particular to a braking system of a pure electric vehicle and an energy feedback control method thereof. Background technique [0002] At present, pure electric vehicles generally do not have the function of braking and braking energy feedback and absorption. The energy generated by braking is lost in the form of heat, and the energy generated by braking cannot be recycled. The driving range under battery conditions also affects the service life of electric vehicles. Therefore, it is very necessary to design a braking system that can recover the braking energy of pure electric vehicles. Contents of the invention [0003] The invention aims to solve the problem that the existing pure electric vehicles do not have the braking energy feedback and absorption function, which leads to the waste of electric energy. It provides a combination of electronic brakes an...
