Abstract

The invention relates to the technical field of cell parallel battery modules, in particular to a 21700 cell series-parallel battery module. The 21700 cell series-parallel battery module comprises a plurality of 21700 battery module units arranged in sequence, and the 21700 battery module units penetrate through a fixed part in sequence and are fixed into a whole; each 21700 battery module unit comprises a module housing and a plurality of 21700 single cells, parallel confluence plates are mounted on two outer walls of the module housing, and a plurality of insertion slots and electrode insertion through holes are provided in two inner walls of the module housing. According to the 21700 cell series-parallel battery module, the 21700 single cells are fixed in the module housing by insertingand clamping, and the 21700 battery module units are correspondingly clamped and limited and penetrate through bolt nut connectors, which can meet the high-strength structure required for the series-parallel battery module composed of 21700 single cells with large capacity, the structure is simple, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the technical field of cell parallel battery modules, in particular to a 21700 battery cell series-parallel battery module. Background technique [0002] In today's society, with the continuous improvement of people's living standards, the demand for cars is increasing. At the same time, energy problems are deepening, petroleum products are gradually in short supply, and environmental pollution is also deepening. How to effectively manufacture a new energy vehicle that can replace traditional vehicles has become the development goal of all automotive companies today. Moreover, the country's strong support for the new energy automobile industry is precisely for this purpose. New energy vehicles can be divided into pure electric vehicles and hybrid vehicles, but no matter which one they are, they are inseparable from power batteries to provide power for them. The power battery as an energy source, due to its own characteristics...
