The invention relates to a method and device for increasing the low-temperature driving range of an electric vehicle, and relates to the technical field of electric vehicle endurance. The method comprises the following steps that when the vehicle is in a driving state, the battery electric quantity and the battery average temperature are obtained; based on the battery electric quantity and the battery average temperature, the heat pump system reduces heating energy consumption in a battery heat recovery mode or an air heat absorption mode. The battery electric quantity and the battery average temperature are obtained, heat is supplied in a battery heat recovery mode or an air heat absorption mode according to data conditions, heating energy consumption of the vehicle is reduced, battery electric quantity consumption is reduced, and therefore the low-temperature driving range is increased.
