Problems solved by technology
[0002] The existing lithium-ion battery market has become increasingly mature, and the scale of various manufacturers is also increasing. The advantages of lithium batteries are gradually reflected, but there are also problems that are difficult to solve, such as the heating problem of lithium battery packs. Lithium battery packs are composed of multiple batteries. Certain rules are arranged to form a battery pack, most of which are arranged in a rectangular shape. During the charging and discharging process of the lithium battery pack, especially for the battery cells in the middle of the battery pack, the heat generated by heat generation is difficult to discharge outward in time, making the battery cells in the middle position The temperature of the cell is higher than that of the cell at the edge, resulting in a large temperature difference of the cell, which affects the performance and life of the lithium battery pack
