Heating film assembly and battery pack
By introducing a shape memory alloy skeleton into the heating film assembly, the high-temperature deformation force is used to re-attach the film body to the battery, which solves the problems of decreased heat conduction efficiency and dry burning caused by the separation of the heating film from the battery, and achieves improvements in safety and economy.

Abstract
The utility model relates to the technical field of batteries, and discloses a heating film assembly and a battery pack, the heating film assembly is used for heating a battery unit comprising a plurality of batteries arranged in sequence, and the heating film assembly comprises a film body, a heating wire and a memory alloy skeleton. The membrane body comprises two membrane sheets, and the two membrane sheets are attached to each other. And the heating wire is arranged between the two membranes. The memory alloy framework is fixedly arranged between the two membranes, the memory alloy framework is suitable for generating deformation under the condition of heating, and the deformation can enable the membrane body to tend to be attached to the battery unit. The memory alloy framework can be straightened again through high temperature generated by dry burning, so that the heating area separated from the battery is tightly attached to the side face of the battery under the action of pulling force, the effects of reducing the dry burning temperature and preventing dry burning are achieved, and dry burning caused by failure of an adhesive layer is avoided.
