A battery module includes a plurality of battery sets in which first unit cells and second unit cells are adjacent to each other. In the first unit cell, a positive electrode terminal and a negative electrode terminal are oriented and extend in a first direction from a first end portion of a first main body. In the second unit cell, a positive electrode terminal and a negative electrode terminal are oriented and extend in a second direction opposite to the first direction from a first end portion of a second main body. Then, in the battery set, at least a part of the first main body and the second main body overlap and are in contact with each other. Further, a heat conductive material that conducts heat from the first unit cell or the second unit cell is in contact with the battery set.

The present disclosure provides a battery unit, a battery module and a battery pack. A battery pack comprises: at least one battery module; and a heating film sheet directly or indirectly heating the at least one battery module. The heating film sheet comprises a heating core and two insulating films. The heating core generates heat when the heating core is electrified, and has: a wire connection region for electrically connecting with external wires; and a heating region electrically connecting with the wire connection region, rated heating powers of different parts of the heating region are different so as to meet demand for heat of each battery module in each of different regions of the at least one battery module when the at least one battery module is heated. The two insulating films respectively cover two sides of the heating core. In the battery pack, each battery module is heated by the heating film sheet, and the rated heating powers of the different parts of the heating region of the heating core are different, so the heat provided for each battery module in the different region of the battery pack can be determined according to the demand for heat of each battery module in the different region of the battery pack, and in turn it ensures that each battery module of the battery pack is heated uniformly by the heating film sheet.
