The invention provides a battery pack temperature control method and device and a vehicle. The method comprises the following steps: acquiring a thermal management mode, a vehicle defrosting mode, a battery cell temperature and a vehicle working condition of a vehicle; when the thermal management mode, the vehicle defrosting mode and the battery cell temperature meet the battery temperature equalization condition, the average temperature and the temperature rise rate of the battery cell are determined according to the battery cell temperature; and cooling or heating the battery pack according to the temperature rise rate under different average temperatures and different vehicle working conditions. The battery pack can be correspondingly cooled or heated by taking the average temperature of the battery cells, the working condition of the vehicle and the temperature rise rate of the battery cells as the control basis, so that the temperature of the battery pack is adjusted, the temperature difference of the battery cells is balanced, the battery pack is kept in a good charging and discharging state, and the charging and discharging performance of the battery pack is improved.

    本发明提供一种电池包温度的控制方法、装置及车辆。该方法包括:获取车辆的热管理模式、车辆除霜模式、电池电芯温度以及车辆工况;当热管理模式、车辆除霜模式以及电池电芯温度满足电池均温条件时,根据电池电芯温度,确定电池电芯的平均温度以及温升率;在不同的平均温度以及不同的车辆工况下,根据温升率对电池包进行冷却或加热处理。本发明能够以电池电芯的平均温度、车辆工况以及电池电芯的温升率为控制依据,对电池包进行对应的冷却或加热处理,以便调节电池包的温度,平衡电池电芯的温差,使得电池包保持在良好的充放电状态中,提高电池包的充放电性能。
