The invention discloses an electric vehicle, a regenerative braking control method and device thereof and a storage medium. The regenerative braking control method comprises the steps that when a brake pedal of the electric vehicle is triggered, SOC of a power battery of the electric vehicle is detected, and whether the SOC of the power battery is smaller than or equal to a preset value or not isjudged; if the SOC of the power battery is smaller than or equal to the preset value, a vehicle speed signal and a wheel speed signal of the electric vehicle are detected, the deceleration of the electric vehicle is calculated according to the vehicle speed signal, and the slip rate of the electric vehicle is calculated according to the vehicle speed signal and the wheel speed signal; and regenerative braking control is performed on the electric vehicle according to the deceleration and the slip rate of the electric vehicle. According to the regenerative braking control method, the ABS triggerfrequency is reduced by controlling regenerative braking, so that the hydraulic basic braking efficiency is the highest, braking safety is guaranteed, and the endurance of the electric vehicle is prolonged.

    本发明公开了一种电动汽车及其再生制动控制方法、装置以及存储介质。其中,再生制动控制方法包括:当电动汽车的制动踏板被触发时,检测电动汽车的动力电池SOC,并判断动力电池SOC是否小于等于预设值;如果动力电池SOC小于等于预设值,则检测电动汽车的车速信号和轮速信号,并根据车速信号计算电动汽车的减速度,以及根据车速信号和轮速信号计算电动汽车的滑移率;根据电动汽车的减速度和滑移率对电动汽车进行再生制动控制。该再生制动控制方法,通过控制再生制动,实现减少ABS触发频率,使液压基础制动效率最高,保证制动安全,增加电动汽车续航。
