One or more embodiments of the invention provide a thermal management method and device for a battery pack. The method comprises the following steps: acquiring a first moment set by a user for supplying power to an external load based on a vehicle battery pack; calculating the temperature cooling time required for starting refrigeration equipment of the vehicle to cool the battery pack so as to cool the battery pack to the optimal temperature; and charging the battery pack based on a charging device so as to recover the SOC of the battery pack to the charging duration required by a preset value, and on the basis of the temperature cooling duration and the charging duration, the starting moment when the refrigeration equipment is started in advance to cool the battery pack before the first moment is calculated. Therefore, the refrigeration equipment can be started at the starting moment to cool the battery pack to the optimal temperature, and the SOC of the battery pack is recovered to the preset value, so that the battery pack is in the optimal state when the battery pack supplies power to the external load.

    本说明书一个或多个实施例提供一种电池包的热管理方法及装置。该方法包括:获取用户设定的基于车辆的电池包对外部负载进行供电的第一时刻;计算开启所述车辆的制冷设备对所述电池包进行冷却,以将所述电池包的温度冷却到最佳温度所需的温度冷却时长;以及,基于充电设备向所述电池包进行充电,以将所述电池包的SOC恢复至预设值所需的充电时长;基于所述温度冷却时长和所述充电时长,计算在所述第一时刻之前提前开启所述制冷设备对所述电池包进行冷却的开启时刻。据此,可以在开启时刻开启制冷设备将电池包冷却到最佳温度,并将电池包的SOC恢复至预设值,从而在电池包对外部负载进行供电时使电池包处于最佳状态。
