Abstract

The invention belongs to the technical field of power batteries of vehicles, and particularly relates to a heating control method of a power battery pack of an electric vehicle. The heating control method is implemented by a whole vehicle instrument, a whole vehicle control unit, a power battery system, a motor control system and a driving motor, wherein the whole vehicle instrument is connected with the whole vehicle control unit, the whole vehicle control unit is connected with the power battery system and the motor control system respectively, and the motor control system is connected with the power battery system and the driving motor respectively. According to the method, power batteries are heated by virtue of an original electric drive system of the electric vehicle, the energy of the power batteries is mainly used for the self heating of the power batteries, so that the temperature of the power batteries can be rapidly raised without extra cost, and the heating efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of automobile power batteries, and in particular relates to a heating control method for electric automobile power battery packs. Background technique [0002] The grim situation of global energy and the environment, especially the huge impact of the international financial crisis on the automobile industry, has pushed countries around the world to accelerate the strategic transformation of transportation energy. New energy vehicles represented by hybrid vehicles, pure electric vehicles and fuel cell vehicles have become the future vehicles important direction of development. [0003] Due to the advantages of high working voltage, large specific energy, long cycle life, and low self-generation rate, lithium-ion power batteries are widely used in electric vehicles, but the output capacity of this type of power battery decreases rapidly with the temperature drop at low temperature decrease, the lower the temp...
