The invention discloses a heat preservation method and device for a vehicle power battery, a vehicle and a storage medium. The method comprises the steps that when a charging port of the vehicle is connected with a charging pile through a charging gun, temperature information of the power battery is obtained in real time, and whether the current temperature of the power battery is smaller than a first preset temperature or not is judged according to the temperature information; if yes, obtaining current electric quantity information of the power battery; according to the current electric quantity information of the power battery, judging whether the current residual electric quantity of the power battery is greater than or equal to first preset electric quantity; if yes, the power battery is controlled to supply power to the electric heating device, so that the electric heating device heats the power battery. According to the technical scheme, the temperature of the power battery can be controlled, the heat preservation cost of the power battery is reduced, and the heat preservation effect is improved.

    本发明公开了一种车辆动力电池的保温方法、装置、车辆及存储介质,该方法包括:在车辆的充电口通过充电枪连接充电桩时,实时获取动力电池的温度信息,根据温度信息,判断动力电池的当前温度是否小于第一预设温度;若是,则获取动力电池的当前电量信息;根据动力电池的当前电量信息,判断动力电池的当前剩余电量是否大于或等于第一预设电量;若是,则控制动力电池为电加热装置供电,以使电加热装置加热动力电池。本发明提供的技术方案能够控制动力电池的温度,降低了对动力电池的保温成本,提高了保温的效果。
