Abstract
The utility model provides a kind of heating film, battery module and battery pack, it is related to battery thermal management technical field, the heating film includes film body and the heating wire being set in film body;Film body includes first heating area, second heating area and third heating area, first heating area is located at film body center, the second heating area is symmetrically arranged in the two sides of first heating area along film body width direction, third heating area is symmetrically arranged in the two sides of first heating area along film body length direction. By zoning gradient heating design, the third heating area maximum heat output to compensate edge heat dissipation, second area is followed by optimizing horizontal heat distribution, first area minimum avoids center overheating, to synchronously solve the temperature difference between module and single cell axial temperature uneven problem, improve heating efficiency while ensuring temperature uniformity and safety.
