摘要
电动汽车行驶时对能量的需求以及延长续驶里程要求驱动电机具有再生制动能力,既可以提供制动力,又可以将制动过程中的能量回收。通过对汽车制动模式及其产生的能量进行分析。以永磁无刷直流电机系统在作电动汽车动力时实现电气制动为控制策略,仿真了回馈制动,并对仿真结果进行了分析、探讨。结果表明,再生制动的算法是可行的,能满足能量回收要求。
According to the energy requirements and extension of driving range. Electrical vehicle （EV） should have a capacity of regenerative braking. EV may not only provide braking force but also recycle the kinetic energy. This kinetic energy can be transformed in electrical energy and be take in battery of EV. In view of the analysis-of braking mode, the permanent magnet brusbless DC motor system is used to fulfill electrical braking with the control strategy during acting as power of EV. Regenerative braking results will be simulated in the computer. And simulation are explored and discussed. The result shows that the design of the mathematic system is feasible. It can meet the need of the kinetic energy.
