The invention relates to a battery heating control method and device, a medium, a system, a vehicle and a chip. The method comprises the steps that first state information of a high-voltage battery and second state information of a low-voltage battery are obtained; and in response to determining that the battery heating condition is satisfied according to the first state information and the second state information, controlling an operating state of a DCDC converter coupled between the high-voltage battery and the low-voltage battery so that the high-voltage battery and the low-voltage battery alternately charge each other. Thus, under the condition that the batteries need to be heated, energy can be converted between the high-voltage battery and the low-voltage battery through the DCDC converter to form positive and negative alternating pulse current, and the positive and negative alternating pulse current can heat the interiors of the high-voltage battery and the low-voltage battery through the battery cells of the high-voltage battery and the low-voltage battery.

    本公开涉及一种电池加热控制方法、装置、介质、系统、车辆和芯片,该方法包括:获取高压电池的第一状态信息和低压电池的第二状态信息;响应于根据第一状态信息和第二状态信息,确定满足电池加热条件,控制耦合在高压电池与低压电池之间的DCDC转换器的工作状态,以使高压电池和低压电池交替为彼此充电。如此,在电池需要加热的情况下,可以通过DCDC转换器将能量在高压电池和低压电池之间进行转换,形成正负交变脉冲电流,正负交变脉冲电流通过高压电池和低压电池的电芯,可对高压电池和低压电池的内部进行加热。
