The invention discloses a low-temperature charging and heating control method, device and equipment for a power battery and a medium, and the method comprises the following steps: obtaining the temperature of each battery cell in the power battery; when it is detected that the lowest temperature in the temperatures of the battery cells in the power battery is smaller than the charging temperature limit value, the charging pile is controlled to output first heating current to supply power to the heating module, so that the heating module heats the power battery; meanwhile, first current in a charging loop of the power battery is detected, first heating current output by the charging pile is adjusted according to the size and the direction of the first current so that all the first heating current can be used for heating of the heating module, and the first heating current initially output by the charging pile is rated current of the heating module. Furthermore, through the control method, the first heating current can be completely used for heating the heating module in the pure heating process of the power battery, and the situation that part of current flows to the power battery, and consequently the performance of the power battery is reduced is avoided.
本发明公开了一种动力电池低温充电加热控制方法、装置、设备和介质,其中,方法包括以下步骤:获取动力电池中各个电芯的温度;当检测到动力电池中各个电芯的温度中的最低温度小于充电温度限值时,控制充电桩输出第一加热电流向加热模组供电,以使得加热模组对动力电池进行加热;同时,检测动力电池的充电回路中的第一电流,并根据第一电流的大小和方向调整充电桩输出的第一加热电流,以使第一加热电流全部用于加热模组加热,其中,充电桩起始输出的第一加热电流为加热模组的额定电流。进而,通过上述控制方法能够在对动力电池进行纯加热的过程中,能够将第一加热电流全部用于加热模组加热,避免了部分电流流向动力电池,造成动力电池性能下降。
