Regenerative Braking Scheme of Pure Electric Vehicle Electro Hydraulic Compound Braking

摘要

In order to increase the effect of regenerative braking system for electric automobile, this paper puts forward a regenerative braking system for electric automobile based on PWM control equivalent model. Firstly, it introduces the integrated controlling system for the regenerative braking system and the selector mode of its controller, and then provides the composition principle of the regenerative braking system for hybrid electric vehicle; secondly, on the basis of PWM control model, it designs the operation principle of the regenerative braking system, and sets up the model of current harmonics; in the end, through simulation experiment, it verifies the efficiency of the methods being proposed.
