电动汽车再生制动控制策略

Strategy of Electric Automobile Regenerative Braking

本文提出了电动汽车再生制动的由来,归纳了再生制动的特点:电机制动转矩有限、再生制动波动较大、SoC会对再生制动造成影响,分析了再生制动的制约因素:SoC、电池组充电功率、车速及驱动轮。并且基于制动力分配,提出了再生制动的并行制动力控制策略。

This paper presents the origin of electric automobile regenerative braking, and concludes its characteristics： torque limited of motor braking, regenerative braking volatility, and SoC （State of Charge） which will have an impact on the regenerative braking. It analyzes the restricting factors of regenerative braking： SoC, battery power, velocity, and driving wheel. Finally the paper puts forward the strategy of paralleled regenerative braking based on the braking force distribution.
