The invention provides a battery pack heating film, a battery pack and a vehicle, and relates to the technical field of heating films. A heating core in the battery pack heating film comprises a first electrode plate and a second electrode plate which are oppositely arranged in a first direction, and a heating film layer located between the first electrode plate and the second electrode plate. According to the structure of the heating core body, current can vertically flow through the heating film layer, heat is uniformly generated according to the power requirement, and the effect of heating the battery pack is achieved. Compared with the prior art, the battery pack heating film has the advantages that an existing heating film plane circuit mode is changed, a vertical circuit structure is designed, the production cost of the battery pack heating film is reduced, and the functionality, the safety and the customizability of the battery pack heating film are improved. And different numbers of heating core bodies are placed according to different heating areas, so that the battery pack heating film can meet the heating requirements of different areas of the same battery pack.
本发明提供了一种电池包加热膜、电池包及车辆,涉及加热膜技术领域。该电池包加热膜中的发热芯体包括在第一方向上相对设置的第一电极片和第二电极片,以及位于第一电极片和第二电极片之间的发热膜层。该发热芯体的结构可以使电流能够垂直地流过发热膜层,均匀地按照功率要求产生热量,达到为电池包加热的效果。相当于是改变了现有的加热膜平面电路模式,设计了垂直的电路结构,降低了电池包加热膜的生产成本,提高了电池包加热膜的功能性、安全性以及可定制性。并且针对不同的加热区域放置不同数量的加热芯体,以使电池包加热膜可以满足同一电池包不同区域的加热需求。
