The invention provides a heating method and device of a vehicle power battery and a storage medium, and belongs to the technical field of battery management. The method comprises the steps that the preset discharge power of a power battery is inquired in a discharge mapping table of the power battery based on the temperature and the remaining capacity of the power battery of the vehicle, and the discharge mapping table is used for recording the preset discharge power of the power battery under different temperatures and remaining capacities; the actual discharge power of the power battery and the target discharge power of the vehicle are obtained, wherein the target discharge power is at least the discharge power to be reached when the vehicle accelerates; and heating the power battery under the condition that the magnitude relationship among the preset discharge power, the actual discharge power and the target discharge power meets the heating condition. According to the technical scheme, a battery heating strategy on the power dimension is provided, the power requirement of the vehicle can be met, meanwhile, heating energy consumption is reduced, and the endurance of the vehicle in the low-temperature environment is improved.
