battery module

Abstract

The invention relates to a new type of battery module, which includes a cell module, an insulating plate, a fixed steel frame, an aluminum sheet, a fixing bolt and a nut, and the cells in the cell module are alternately arranged with positive and negative poles, and any two adjacent The polarity setting between the cells is reversed, the number of cell modules is more than 3, aluminum sheets are arranged between adjacent cell modules, the number of aluminum sheets is one group less than the number of cell modules, and the copper There are two sets of copper sheets, insulating plates and fixed steel frames. The two sets of copper sheets, insulating plates and fixed steel frames are respectively arranged at both ends of the two outermost cell modules from the inside to the outside, and are connected by bolts and nuts. The cooperation between them is fixed, which improves the assembly efficiency and improves the safety performance at the same time.

Description

technical field [0001] The invention relates to a battery module, in particular to a novel battery module with good safety performance. Background technique [0002] When the existing modules are assembled into a module, there are the following problems: [0003] ①Because of the polarity of the battery cell, it is necessary to judge the polarity of the battery cell before assembling, and then assemble it. The more modules there are, the more time it takes to judge the polarity. If there is a wrong judgment, the modules are installed backwards. , it will cause the entire string of voltage to be lost, and it will also cause the voltage acquisition board to be burned, and the production efficiency and quality will be affected; [0004] ② It is impossible to effectively isolate the front and rear modules, and at the same time, there will be problems with the contact between modules; [0005] ③The battery support has no explosion vent slots, and when the battery explodes, high ...

Problems solved by technology

[0003] ①Because of the polarity of the battery cell, it is necessary to judge the polarity of the battery cell before assembling, and then assemble it. The more modules there are, the more time it takes to judge the polarity. If there is a wrong judgment, the modules are installed backwards. , it will cause the entire string of voltage to be lost, and it will also cause the voltage acquisition board to be burned, and the production efficiency and quality will be affected;

[0004] ② It is impossible to effectively isolate the front and rear modules, and at the same time, there will be problems with the contact between modules;

[0005] ③There is no explosion vent slot in the cell bracket, so when the cell explodes, high temperature and high pressure cannot be eliminated, posing a safety hazard
