The invention discloses a driving control method for a long downhill slope of an electric vehicle, the electric vehicle and a storage medium. The driving control method comprises the steps of determining whether the vehicle enters a long downhill working mode; if the vehicle enters the long downhill working mode, whether the SOC value of a power battery is larger than or equal to a preset value ornot is judged, if yes, the power battery is not charged, controlling a high-voltage component assembly to work to consume braking energy; if not, carrying out the next step; calculating the absorption power P0 when the whole vehicle absorbs the brake energy; judging whether the maximum charging power Pmax of the power battery is greater than or equal to P0; if yes, completely using the braking energy for charging the power battery; and if not, using the braking energy for full-load charging of the power battery, and meanwhile, controlling the high-voltage component assembly to work to consumeredundant braking energy. Under the working condition of long downhill, the high-pressure component assembly is combined for braking energy recovery, the cost is reduced, and the driving experience is also improved.

    本发明公开了一种电动汽车长下坡的驱动控制方法、电动汽车及存储介质。驱动控制方法包括步骤:判断车辆是否进入长下坡工作模式;若所述车辆进入长下坡工作模式,则判断动力电池的SOC值是否大于等于预设值,若是,则所述动力电池不充电,控制高压部件总成工作消耗制动能量;若否,则进行下一步;计算整车吸收制动能量时的吸收功率P0;判断所述动力电池的最大充电功率Pmax是否大于等于P0;若是,则制动能量全部用于对所述动力电池充电;若否,则制动能量用于所述动力电池满负荷充电,同时控制所述高压部件总成工作消耗多余的制动能量。本发明在长下坡工况下结合高压部件总成进行制动能量回收,降低了成本,也提升了驾驶体验。
