Abstract

The invention discloses a soft package battery module. The module comprises multiple battery cells, a module shell and a heat-conducting filler, wherein all the battery cells are electrically connected through corresponding tabs; all the battery cells are arranged in the module shell; the heat-conducting filler is arranged in the module shell; gaps between the battery cells and between the batterycells and the module shell are filled with the heat-conducting filler; all the battery cells are fixed by the heat-conducting filler; and the module shell is made of a heat-conducting material. The invention further discloses electric equipment comprising the soft package battery module. According to the soft package battery module and the electric equipment disclosed in the invention, the heat dissipation performance is good, abrasion caused by friction between the battery cells is avoided, and the soft package battery module is small in size and convenient to install and arrange.

Description

technical field [0001] The invention relates to the battery field, in particular to a pouch battery module and electrical equipment. Background technique [0002] Lithium-ion batteries have the advantages of large battery capacity and small size. Lithium-ion batteries often include several pouch battery modules, and the pouch battery module is formed by connecting multiple cells in series and parallel, such as figure 1 As shown, the cells 1 of the existing pouch battery module are fixed by the frame 6, and the frames 6 of each cell 1 are fixed in series by long connecting rods and bolts, so that each cell 1 is overlapped and fixed to form a pouch battery module , the fixing method between the cells of the pouch battery module mainly has the following problems: 1. There is a gap between the cells 1 after overlapping and fixing, and the cells 1 will generate heat when they work, and the gap between the cells 1 The air in the air will form an insulating layer, which is not co...
