Abstract:
Disclosed in the present application is a battery pack. The battery pack comprises: a bottom casing, a battery cell module, a heating assembly and an insulation layer, the bottom casing being provided with an accommodation recess therein, the battery cell module being arranged in the accommodation recess, the heating assembly being arranged between the recess bottom of the accommodation recess and the battery cell module, the heating assembly comprising a heating film body, and the insulation layer being arranged between the recess bottom of the accommodation recess and the heating assembly. The battery pack further comprises a heat conduction adhesive layer arranged between the heating film body and the battery cell module. In the present application, the heat conduction adhesive layer helps to ensure the strength and reliability of the heating film body, and additionally, the heat conduction adhesive layer can also increase the efficiency of heat exchange between the heating film body and the battery cell module; and the insulation layer helps to achieve a protection effect on the heating assembly when the battery pack suffers from vibration and impact, thereby effectively avoiding the problems of short-circuits due to abrasion of the heating assembly, and thermal failures of the battery pack, thus ensuring the heating reliability of the heating assembly.
