Lithium battery explosion-proof module

Abstract

The invention discloses a lithium battery explosion-proof module, which comprises a module shell with a circular structure. There is a circular mounting cavity in the middle of the module shell, and a bearing mounting hole is respectively opened on both sides of the mounting cavity. The bearing mounting hole A bearing is installed inside, and a hollow rotating shaft is installed in the shaft socket of the bearing. There is a wire inlet cavity in the middle of the hollow rotating shaft. hole, the two ends of the hollow rotating shaft are installed in the bearing hole of the bearing and one end protrudes from the outside of the module casing; the invention adopts a circular rotating structure to effectively disperse each lithium battery, and utilizes the rotating structure, It can be effectively applied in various vibration environments, can effectively solve heat dissipation and vibration problems, and use physical methods to judge whether there is expansion after the lithium battery expands, and find the problem of the lithium battery at the first time, increasing the safety of use.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to an explosion-proof module for lithium batteries. Background technique [0002] The combination of large-scale lithium batteries has become a new energy supply method. Large-scale lithium batteries have high power and high heating efficiency, which is dangerous. Once the battery is overheated or overheated for a long time, the battery will swell. The reason is that the lithium battery is likely to swell. If it continues to be used, the swollen lithium battery may leak or even explode. As you know, the safety performance is poor. [0003] Furthermore, the distance between the batteries in the lithium battery pack is very close, and the installation methods are stacked or side-by-side. Although the stacked or side-by-side installation structure is adopted, in the same space during installation, The number of lithium batteries installed is not very large, and the arrangement of the...

[0002] The combination of large-scale lithium batteries has become a new energy supply method. Large-scale lithium batteries have high power and high heating efficiency, which is dangerous. Once the battery is overheated or overheated for a long time, the battery will swell. The reason is that the lithium battery is likely to swell. If it continues to be used, the swollen lithium battery may leak or even explode. Knowing that the safety performance is poor

[0003] Furthermore, the distance between the batteries in the lithium battery pack is very close, and the installation methods are stacked or side-by-side. Although the stacked or side-by-side installation structure is adopted, in the same space during installation, The number of lithium batteries installed is not very large, and the arrangement of batteries still takes up a lot of space. Due to the compact arrangement, once one of the lithium batteries burns and explodes due to rapid heating such as bulging, it will cause the entire lithium battery pack to be damaged. Due to the compact structure and poor heat dissipation performance, when used in a vibrating environment, the buffer performance of lithium batteries is required to be high
