Abstract

The invention relates to the technical field of cell parallel battery modules, in particular to a 21700 cell parallel battery module. The battery module comprises a module housing and a plurality of 21700 single cells. A confluence plate is installed on the outer walls of two sides of the module housing, a plurality of insertion slots are arranged on the inner walls of two sides of the module housing, through holes for electrode piercing are mounted on the two side walls of the module housing, the through holes of the electrode piercing correspond to the positions of the insertion slots one byone, and a plurality of confluence pieces on each confluence plate are connected with the electrodes at both ends of the 21700 single cells one by one, respectively. According to the 21700 cell parallel battery module disclosed by the invention, the 21700 single cells is fixed in the module housing in an inserting and clamping manner by installing the plurality of insertion slots for installing the 21700 single cells in the module housing, and the 21700 cell parallel battery module can meet the high-strength structure required for the parallel battery module composed of the 21700 single cellswith large capacity, and has a simple structure and is low in manufacturing cost.

Description

technical field [0001] The invention relates to the technical field of batteries connected in parallel with batteries, in particular to a battery module with 21700 batteries connected in parallel. 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 t...
