The invention provides a vehicle power battery pre-charging method and device, a vehicle and a storage medium, the method is applied to the field of vehicle charging, and the method comprises the steps that under the condition that a power battery is in a pre-charging stage, the pre-charging duration of the power battery and battery pack working parameters of the power battery are obtained, the battery pack working parameters are used for representing the running state of the battery pack of the power battery; determining a target pre-charging voltage according to the pre-charging duration and the working parameters of the battery pack; and sending the target pre-charging voltage to the charging pile, so that the charging pile charges the power battery at the target pre-charging voltage. According to the method, in the pre-charging process of the power battery, the pre-charging voltage can be flexibly adjusted in real time, and the pre-charging success rate of the power battery is increased.

    本申请提供了一种车辆动力电池预充电的方法、装置、车辆和存储介质,该方法应用于车辆充电领域,该方法包括:在动力电池处于预充阶段的情况下,获取动力电池的预充时长和动力电池的电池包工作参数,电池包工作参数用于表示动力电池的电池包的运行状态;根据预充时长和电池包工作参数,确定目标预充电压;将目标预充电压发送至充电桩,以使充电桩以目标预充电压对动力电池进行充电。该方法能够在动力电池预充过程中,实时灵活地调整预充电压,提高动力电池的预充成功率。
