Description

Technical Field

[0001] The utility model relates to the technical field of battery busbars, in particular to a battery module CCS upper cover which is easy to disassemble. Background Art

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage and use of lithium metal are very demanding on the environment. With the development of science and technology, lithium batteries have become mainstream. As a clean and efficient new energy source, lithium-ion power batteries are widely used in various industries such as automobiles, ships, forklifts and energy storage. In order to meet the use requirements of different working conditions, it is usually necessary to combine several single cells into a battery module, and then several battery modules are combined with various electrical components to form a battery pack in a sealed box for customers to use.

[0003] At present, the CCS top cover of the battery module is mainly fixed with double-sided tape or with an additional small clip to fix the blister cover to the aluminum bar of the product. However, both methods have disadvantages. The first method is not easy to disassemble and replace after sticking with double-sided tape, and forced disassembly and replacement may damage the product; the second method uses clips to fix, which increases costs. Utility Model Content

After the upper cover plate and the lower cover plate are combined and installed by the card block and the buckle, the fixing mechanism is controlled by a button, so that the shell can be quickly opened and combined, and the independently placed battery stack of the battery pack inside the shell can be more conveniently disassembled and replaced during the disassembly process, thereby achieving the effect that the shell can be opened and closed more conveniently during use through the fixing mechanism on the shell surface, and the multiple battery packs inside the shell can be more conveniently disassembled and replaced during use.

[0015] 2. This kind of battery module CCS upper cover which is easy to disassemble has a fixing plate in the middle of the inner bottom wall surface of the shell, and the surface of the fixing plate has an installation groove, through which the conductive copper-aluminum plate used for installation can be installed inside the shell, and the insulating filling material opened on the inner bottom wall of the shell makes the shell better protect the battery pack from overheating after being installed inside the shell and from causing short circuit of the battery pack during use.
