[0003] With the continuous development of the economy, people's purchasing power has been greatly improved. Buying a car is no longer a luxury. During the braking process, the kinetic energy is converted into the heat energy of the brake pads, which wastes a lot of energy. Utilizing this part of energy will undoubtedly contribute to energy saving and emission reduction. Related braking energy recovery systems have also appeared in the prior art. Most of the existing braking energy recovery systems only consider the recovery and conversion of braking energy, and do not take into account the reliability of braking. In view of this, there is indeed a need for a new type of braking energy recovery device to play The role of energy saving and auxiliary braking

Description
Technical field [0001] The present invention relates to the technical field of energy recovery equipment, and more particularly to a car auxiliary brake energy recovery device. Background technique [0002] Brake energy recovery is one of the important technologies of modern electric vehicles and hybrid powers, and it is also an important feature. In a general internal combustion engine, when the vehicle decelerates, when braking, the motion energy of the vehicle is converted into thermal energy through the brake system, and is released to the atmosphere. In the electric vehicle and the hybrid vehicle, this waste of motion energy has been converted into electrical energy by braking energy recovery techniques and stored in the battery, and further converted to drive energy. For example, when the vehicle starts or accelerates, when the driving force needs to increase the driving force, the motor driving force becomes an auxiliary power of the engine, so that the power can obtain an...
