The invention discloses a battery heating method and device, a storage medium and an automobile, and relates to the technical field of automobiles. The method comprises the steps that first charging time and second charging time are determined, the first charging time is used for indicating the charging time needed for fully charging a battery when battery heating is started after an automobile arrives at a charging pile, and the second charging time is used for indicating the charging time needed for fully charging the battery when battery heating is started before the automobile arrives at the charging pile; when the first charging time is longer than the second charging time, battery heating is started before the automobile arrives at the charging pile; and when the first charging time is smaller than or equal to the second charging time, battery heating is started after the automobile arrives at the charging pile. Before the vehicle arrives at the charging pile, battery heating is started in advance to heat the battery to the proper temperature, so that the battery fast charging efficiency under the low-temperature working condition is improved, the charging time of the battery is shortened, the influence of heating the battery in advance on the charging time can be determined, and energy waste is avoided.

    本申请公开了一种电池加热方法、装置、存储介质及汽车,涉及汽车技术领域。方法包括:确定第一充电时间和第二充电时间,第一充电时间用于指示汽车到达充电桩后开启电池加热时电池充满电所需的充电时间,第二充电时间用于指示汽车到达充电桩之前开启电池加热时电池充满电所需的充电时间;当第一充电时间大于第二充电时间时,在汽车到达充电桩之前开启电池加热;当第一充电时间小于等于第二充电时间时,在汽车到达充电桩之后开启电池加热。通过在车辆到达充电桩之前,提前开启电池加热将电池温度加热至适宜温度,以提升低温工况电池快充效率,缩短电池的充电时间,还可以确定提前加热电池对充电时间的影响,避免能量的浪费。
