Problems solved by technology

At present, the use of large-scale groups of soft-packaged lithium batteries is gradually increasing, and the series-parallel connection between batteries is also relatively complicated, while the traditional connection method is based on welding or crimping the battery tabs on the metal conductive bar. It is not suitable for some occasions where the internal space is limited and easy installation and disassembly are required, and it is not suitable for occasions that require diversification and complexity of series and parallel connections

Abstract

A lithium battery connecte structure for flexible package relates to that technical field of chemical power supply, and is characterized in that at least a printed circuit board is arranged in which aserie-parallel circuit is arranged; A plurality of mounting holes are arranged on the printed circuit board; The mounting hole is arranged on the series-parallel circuit; A plurality of lithium battery cells, M lithium battery cells correspond to one mounting hole, and battery pole ears of the lithium battery cells are inserted into the mounting hole to be communicated with series-parallel circuits; At least one connector connected with the peripheral device is fixed on the printed circuit board and connected with the series-parallel circuit. The invention adopts a printed wiring board as themain body of battery connection, and the printed wiring board has multiple functions. At first, that battery electrode lug is mechanically connected with the printed circuit board through a screw, and the fixation of the battery electrode lug is realized. The method is simple and easy to operate, reduces the human cost of the operation of the battery group, and saves space; At the same time, it can avoid the harm caused by human error.

Description

technical field [0001] The invention relates to the technical field of chemical power sources, in particular to a flexible packaging lithium battery connection structure. Background technique [0002] Due to the advantages of high specific energy, high voltage and convenient use, lithium battery packs are widely used in civil, industrial, military and other fields. As one of many packaging forms, flexible packaging (polymer) lithium batteries are more and more popular in various application fields due to their more convenient manufacturing process and the characteristics of changing their shape at will, especially mobile phone batteries. Basically this way. At present, the use of large-scale groups of soft-packaged lithium batteries is gradually increasing, and the series-parallel connection between batteries is also relatively complicated, while the traditional connection method is based on welding or crimping the battery tabs on the metal conductive bar. It is not suitab...
