摘要： The present application relates to a heating assembly, a battery and an electric device. A heating sheet (31) is attached to the surface of a battery cell (20) to heat the battery cell (20). When the battery cell (20) is heated and expanded, cracks (3111) can break under the expansion force of the battery cell (20), so that the heating sheet (31) is deformed synchronously with the battery cell (20), thereby preventing the heating sheet (31) from being separated from the battery cell (20). Therefore, the heating efficiency of the heating sheet (31) on the battery cell (20) can be improved.

摘要： A battery pack (10), a power consuming device, and a method for manufacturing the battery pack (10). The battery pack (10) comprises a battery cell (20) and a support member (30). The battery cell (20) comprises two or more secondary batteries (21). The battery cell (20) comprises an intermediate portion (20b) and two end portions (20a). In an arrangement direction of the secondary batteries (21), the two end portions (20a) are located on two sides of the intermediate portion (20b), respectively. The support member (30) is used for supporting the battery cell (20). The support member (30) comprises a body (31) and a heat-resistant component (32) provided to the body (31). The heat-resistant component (32) is arranged corresponding to the at least one end portion (20a), such that the heat exchange amount of the end portions (20a) passing through the support member (30) is less than the heat exchange amount of the intermediate portion (20b) passing through the support member (30). The heat exchange amount of the end portions (20a) of the battery cell (20) of the battery pack (10) is reduced, so that the temperature difference between the end portions (20a) of the battery cell (20) and the intermediate portion (20b) of the battery unit (20) is reduced, thereby increasing the working efficiency of the battery pack (20).
