Abstract

The invention provides a battery module with a heating film. The battery module is applied to the technical field of new energy automobile battery packs and comprises a module support (1), wherein a plurality of battery cells (2) are clamped in the module support (1) and form a battery module body (3), a plurality of busbars (4) are arranged on the battery module body(3), the heating film (5) is arranged on the battery module body(3), and the heating film (5) is a structure clamped between the busbars (4) and the module support (1). According to the battery module with the heating film, the arrangement thought and the structure of the heating film are changed, so that when a battery pack works, the battery cells can be uniformly heated, the safety and the endurance mileage of a new energyautomobile battery are guaranteed, the service life of the battery pack is prolonged, the problem that a battery pack cannot be charged and discharged at a low temperature or the charge-discharge rateis low in the prior art is solved, and the overall performance of the battery pack is improved.

Description

technical field [0001] The invention belongs to the technical field of battery packs for new energy vehicles, and more specifically relates to a battery module with a heating film. Background technique [0002] With the global energy crisis, environmental pollution and other issues becoming increasingly prominent, new energy vehicles have become the focus of the development of domestic and foreign automobile companies. The core components of new energy vehicles are motors, motor controllers and battery packs. The battery pack is assembled from a battery module, and the battery module is composed of multiple batteries connected in parallel. However, the battery pack cannot be charged and discharged in a low-temperature environment or the charge-discharge rate is relatively low, which will cause the battery pack to malfunction or operate in a low-temperature environment. Therefore, the battery pack must be kept at an appropriate temperature. Efficient charge and discharge. T...
