The invention belongs to the technical field of automobiles, and discloses a battery pack pre-cooling method, device and equipment and a storage medium. The method comprises the steps that an in-transit cooling signal is obtained, and the current mode of a vehicle is adjusted to be a pre-cooling mode; detecting the current temperature of the battery cell in real time; when the current temperature of the battery cell is greater than a set temperature threshold value, starting a battery pack cooling function; when it is detected that the charging gun performs charging, the cooling function is closed, and pre-cooling of the battery pack is achieved; the battery cell temperature is monitored in real time according to the in-transit cooling signal generated before charging by a user, whether the battery is cooled in advance is judged according to the battery cell temperature, cooling can be controlled according to the actual battery cell temperature, meanwhile, battery cooling is stopped in time during charging, battery pre-cooling before charging is achieved, and the charging efficiency is improved. The situation that when a pure electric vehicle is charged in a high-temperature environment, a battery cell is at a high temperature and rises to a current limiting temperature along with charging, so that the later charging current of the whole vehicle is small, and the charging duration is affected is avoided.

    本发明属于汽车技术领域,公开了一种电池包预冷却方法、装置、设备及存储介质;该方法包括:获取在途冷却信号,调整车辆当前模式为预冷却模式;实时检测电池电芯的当前温度;在电池电芯当前温度大于温度设定阈值时,启动电池包冷却功能;在检测到充电枪进行充电时,关闭冷却功能,实现电池包预冷却;本发明通过在用户进行充电之前产生的在途冷却信号,实时监控电池电芯温度,根据电池电芯温度判断是否提前进行电池冷却,能够根据实际电池电芯温度控制降温,同时在进行充电时及时关闭电池冷却,实现充点前电池预冷却,避免纯电动汽车在高温环境下充电时,电芯处于较高的温度同时随着充电上升至限流温度,导致整车后期充电电流较小,影响充电时长。
