The invention provides a battery heating control method and device, equipment and a medium. The method comprises the steps of obtaining the current initial temperature of a battery when the battery is in a non-heating state, when it is determined that the current initial temperature is smaller than a preset heating temperature threshold value, according to the current initial temperature, determining a target heating temperature corresponding to the maximum value of the energy gain of the battery, and controlling the battery to be heated to the target heating temperature. By adopting the embodiment of the invention, the energy gain and the energy loss generated by the battery can be considered when the battery is heated, and the discharge energy of the battery is maximized when the battery is heated by calculating the target heating temperatures which meet the maximum energy gain of the battery and correspond to different initial temperatures; therefore, the endurance mileage of the vehicle is further improved, and the energy consumption of the whole vehicle is reduced.

    本发明提供了一种电池加热控制方法、装置、设备及介质,该方法包括:在电池处于非加热状态时,获取所述电池的当前初始温度;当确定所述当前初始温度小于预设加热温度阈值时,根据所述当前初始温度,确定使所述电池的能量增益达到最大值对应的目标加热温度;控制所述电池加热至所述目标加热温度。采用本发明实施例,能够在电池加热时考虑电池自身所产生的能量增益和能量损耗,通过计算电池在不同初始温度下对应的满足电池最大能量增益的目标加热温度,使电池在加热时实现放电能量的最大化,从而进一步提升了车辆的续航里程,降低了整车能耗。
