The invention discloses a method and a system for preventing over-charging and over-discharging of a battery based on an automobile motor. The method comprises the following steps: acquiring currently available maximum charging and discharging power of the battery and preset data of the motor in real time; calculating a torque value according to the maximum charging and discharging power and the corresponding operation efficiency and rotating speed; and adjusting the torque output of the motor according to the torque value. The problem that the battery is overcharged and overdischarged when the power of the motor is unbalanced is solved, the torque of the motor is controlled, the battery is prevented from being overcharged and overdischarged, and the service life of the battery is prolonged.

    本发明公开了一种基于汽车电机防止电池过充和过放的方法及系统,其包括实时获取电池当前可用的最大充放电功率和电机的预设数据;根据最大充放电功率及其对应的运行效率和转速计算扭矩值;根据扭矩值调整电机的扭矩输出。解决了电机功率不平衡时,会导致电池过充过放的问题,实现了控制电机扭矩,避免电池过充过放,提高了电池的使用寿命。
