The invention provides a battery preheating method and device. The battery preheating method comprises the steps that under the condition that a battery preheating state of the vehicle is in an activated state, whether the temperature of a possible temperature interval of battery charging and discharging meets a preheating starting condition or not is estimated according to battery information, the temperature of the possible temperature interval of battery charging and discharging is used as the assumed battery temperature of the vehicle reaching the charging equipment through the preheated battery, and the preheating starting condition is used for reflecting the optimal balance condition of time saving and system energy consumption; determining a target temperature according to the assumed battery temperature corresponding to the preheating starting condition; and preheating the battery according to the target temperature. Therefore, the advantages of quick charging can be achieved, and the charging time is shortened.

    本申请提供一种电池预加热方法及装置。其中,该电池预加热方法包括:在车辆的电池预加热状态处于激活状态的情况下,根据所述电池信息,预估电池充放电的可能温度区间的温度是否符合预加热启用条件,所述电池充放电的可能温度区间的温度用于作为车辆经预加热电池抵达充电设备的假定电池温度,所述预加热启用条件用于反映节省时间与系统能耗的最优均衡条件;根据符合预加热启用条件对应的假定电池温度,确定目标温度;根据所述目标温度,预加热所述电池。如此,可以使快充发挥优势,缩短充电时间。
