The application discloses a sliding energy recovery method. The method comprises the steps that in the running process of an electric vehicle, whether the electric vehicle meets the triggering condition of sliding energy recovery or not is judged; whether the power battery is allowed to be charged or not is determined when the electric vehicle meets the triggering condition of sliding energy recovery; when the power battery is allowed to be charged, a contactor is controlled to be connected with the power battery so as to convert sliding kinetic energy of the electric vehicle into electric energy to be stored in the power battery; and when the power battery is not allowed to be charged, the contactor is controlled to be disconnected with the power battery, one of a front motor and a rear motor is controlled to enter an energy recovery mode to recover energy, and the other one of the front motor and the rear motor is subjected to flux weakening treatment to consume energy recovered by the front motor or the rear motor. The application further discloses a sliding energy recovery system, an electric vehicle and a computer readable storage medium, and when the electric vehicle triggersthe sliding energy recovery condition, the electric vehicle can recover sliding energy to charge a battery or supply power to a power consumption device.

    本申请公开了一种滑行能量回收方法。包括:在电动汽车的行驶过程中,判断电动汽车是否满足滑行能量回收的触发条件;在电动汽车满足滑行能量回收的触发条件时,判断动力电池是否允许充电;在动力电池允许充电时,控制接触器与动力电池导通,以将电动汽车的滑行动能转化为电能存储到动力电池中;和在动力电池不允许充电时,控制接触器与动力电池断开,并控制前电机与后电机中的一个进入能量回收模式以回收能量,另一个进行弱磁处理以消耗通过前电机或后电机回收的能量。本申请还公开了一种滑行能量回收系统、电动汽车及计算机可读储存介质,在电动汽车触发滑行能量回收的条件时,使电动汽车能够回收滑行能量给电池充电或用于耗电器件的供电。
