The invention relates to a power battery control method and device of a vehicle, the vehicle and a storage medium, and the method comprises the steps that the current whole vehicle working mode of the vehicle is recognized; determining the available maximum discharge power of a power battery of the vehicle according to the whole vehicle working mode, and generating an optimal power output strategy of the power battery based on the available maximum discharge power; and controlling the output power of the power battery based on the optimal power output strategy and the actual load power demand of the vehicle. Therefore, the technical problem that the service life of the battery is shortened due to the fact that the discharging capacity of the battery is difficult to fully release due to the fact that different power compositions of the hybrid power vehicle model in different working modes are not considered in the related technology is solved.

    本申请涉及一种车辆的动力电池控制方法、装置、车辆及存储介质,其中,方法包括:识别车辆的当前整车工作模式;根据整车工作模式确定车辆的动力电池的可用最大放电功率,并基于可用最大放电功率生成动力电池的最佳功率输出策略;基于最佳功率输出策略和车辆的实际负载功率需求控制动力电池输出功率。由此,解决了相关技术中,未考虑到混合动力车型在不同工作模式下动力组成不同,导致难以充分释放出电池的放电能力,从而降低电池的使用寿命的技术问题。
