摘要： A battery module includes a housing, a cell assembly, a first elastic member, and a first conductive member. The cell assembly is disposed in the housing. The cell assembly includes a plurality of cell units arranged along a first direction. Each cell unit includes a cell. Along the first direction, the first elastic member is disposed between the cell assembly and the housing. The first elastic member is configured to apply pressure to the cell assembly and provide a swelling space for the cell. Along the first direction, an end of the first conductive member is fixedly connected to the first elastic member. The first conductive member includes a buffer part. The buffer part is configured to be stretched along the first direction by the first elastic member when the cell assembly swells.

摘要： A heating device includes at least two heat emitting bodies, at least one conductive portion, and an insulator. The plurality of heat emitting bodies are spaced apart along a first direction, with a clearance provided between two adjacent heat emitting bodies. The two adjacent heat emitting bodies are connected by the conductive portion. The conductive portion is separate from the clearance. The insulator overlays at least a part of a surface of the heat emitting body. In the heating device, a plurality of heat emitting bodies are spaced apart along the first direction, and a clearance is formed, thereby facilitating bending and deformation of the heating device in a clearance region between the adjacent heat emitting bodies. The conductive portion that connects the two adjacent heat emitting bodies is separate from the clearance.

摘要： A battery pack includes a housing and a cell assembly. The housing includes a first housing and a second housing. A first space is formed in the first housing. The first housing includes a plurality of sidewalls and a bottom wall connected to the plurality of sidewalls and form the first space. The cell assembly is accommodated in the first space. A first clearance is formed between the cell assembly and the plurality of sidewalls. A first through-hole is disposed on at least one of a sidewall or the bottom wall. The first through-hole extends through the sidewall or the bottom wall. The first through-hole is in communication with the first clearance. The first filler is detachably disposed in the first through-hole. A second clearance exists between the first filler and the first through-hole. The second clearance is configured to allow a gas to escape.

摘要： A battery pack includes a housing assembly, a cell assembly, a first circuit board, a support, and a thermally conductive member. The cell assembly is accommodated in the housing assembly. The cell assembly includes a plurality of cells. Each cell includes a cell housing, an electrode assembly disposed in the cell housing, and an electrode terminal connected to the electrode assembly and extending out of the cell housing. The electrode terminal runs through the first circuit board and is connected to a side of the first circuit board facing away from the cell housing. The support is connected to the first circuit board, where the first circuit board is disposed between the cell housing and the support. The support is provided with a first opening, and the thermally conductive member is disposed in the first opening. The thermally conductive member is connected to at least some of electrode terminals.
