Novel battery module

Abstract

The invention relates to a novel battery module which comprises cell modules, insulating plates, fixing steel frames, aluminum sheets, fixing bolts and nuts, wherein cells in the cell modules are arranged in the form of alternate anode and cathode; the polarities between any two adjacent cells are oppositely arranged; the quantity of the cell modules is more than three; the aluminum sheets are arranged between adjacent cell modules; the quantity of aluminum sheets is one set less than the quantity of the cell modules; the quantities of the aluminum sheets, the insulating plates and the fixing steel frames are two sets; the two sets of aluminum sheets, insulating plates and fixing steel frames are respectively arranged at the two ends of the outmost two cell modules from inner to outer and are fixed through the cooperation of the bolts and nuts, so that the assembling efficiency is increased and the safety performance is promoted.

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
