Description

Technical Field

[0001] The utility model relates to the technical field of battery heating films, in particular to a battery heating film with better heat dissipation effect. Background Art

[0002] With the support of national new energy vehicle policies and technological development, although the technology of power batteries has made great progress in recent years, the problems of low temperature and battery attenuation still plague the widespread promotion and application of pure electric vehicles. The optimal discharge temperature of lithium batteries used in electric vehicles is between 30℃ and 35℃. When the ambient temperature decreases, the internal resistance of the battery increases, and the viscosity of the battery electrolyte increases, the battery's charge and discharge performance decreases. Starting an electric vehicle at a low temperature below 10℃ may cause lithium accumulation in the lithium battery, or uneven growth of lithium metal may cause internal short circuits in the positive and negative electrodes of the lithium battery. Therefore, it is necessary to heat the power battery before starting.

[0003] When heating the battery, a heating film is needed for heating. However, after the heating film is used, the heating film does not have the heat dissipation function, which causes the residual heat to continue to heat the battery after the heating film completes heating the battery, causing the battery heating temperature to be too high.
