【摘要】 电动汽车的驱动电机运行在再生发电状态时,既可以提供制动力,又可以给电池充电回收车体动能,从而延长电动车续驶里程。本文对制动模式进行了分类,并详细探讨了中轻度刹车时制动能量回收的机制和影响因素。作者提出了制动能量回收的最优控制策略,给出了仿真模型及结果。最后基于仿真模型及XL型纯电动车对控制算法的效果进行了评价。更多还原

【Abstract】 When the driving electric motor of electric vehicle runs on the state of regeneration, it can not only provide braking force, but also recover some kinetic energy of vehicle to charge the storage battery and elongate the vehicle driving miles. This paper sorts braking modes, researching the principles and affecting factors in detail. The writer puts forward the optimization control algorithm of energy recovery and the result of simulation. At last, the efficiency of control algorithm is valued on the base of simulation model and XL pure electric vehicle.更多还原
