Regenerative Braking Technology in Vehicle

Nowadays, the world car ownership is rapidly expanding, and 99.9% of which are traditional energy vehicles.The energy consumption and environmental pollution pressure it brings has become a global challenge.In this background, energy recovery has become an effective way to ease the pressure of energy and environment.Automotive braking energy has been exploited and motor regenerative braking system has been developed but there are a lot of problems, which need to be solved.In this paper, we review the motor regenerative braking system on the principle of regenerative braking, energy conversion and storage, control strategy and key technologies and so on, at the same time put forward the problems which need to be solved.
