The invention relates to a torque distribution method and device, electronic equipment and a storage medium. The method comprises the steps that the current battery temperature of a high-voltage battery running in the low-temperature environment and the torque required by a driver are obtained; determining target charging and discharging power of the high-voltage battery at the current battery temperature according to the current battery temperature and the battery charge capacity of the high-voltage battery; according to the target charging and discharging power and the actual power of the driving motor, determining the power generation power required by the range extending system; and according to the generated power and the optimal efficiency curve of the range extending system, the target engine rotating speed and the target engine torque of the engine and the target generator rotating speed and the target generator torque of the generator are determined. According to the invention, the generated power can be adjusted along with the temperature, so that the battery does not need to work near a power limit value for a long time, the safety of the high-voltage battery is improved, and the drivability can also be improved; and in a low-temperature environment, the torque of the engine can be kept accurate, so that the accuracy of the charging power can be guaranteed.
