Description

Technical Field

[0001] The utility model relates to the technical field of energy storage batteries, in particular to a lightweight soft-pack lithium battery energy storage box. Background Art

[0002] Lithium battery is a device for energy conversion and storage. It converts chemical energy or physical energy into electrical energy through reaction. It is cleaner than traditional power generation. Lithium batteries can be divided into steel shell batteries, aluminum shell batteries and soft-pack lithium batteries according to the shell material. The weight of soft-pack batteries is 40% lighter than that of steel shell lithium batteries of the same capacity, and 20% lighter than that of aluminum shell batteries. Therefore, it has a good lightweight effect when used. When in use, it will be installed inside the lightweight soft-pack lithium battery energy storage box. The existing lightweight soft-pack lithium battery energy storage box mostly adopts a single-layer structure. During transportation and use, the edges and the four corners of the lower end are easily bumped and deformed. In order to ensure the structural strength, thicker plates are usually used. The thick and heavy plates are not conducive to lightweighting. When the plates are thin, their own strength is low and cannot provide good protection for the soft-pack lithium battery. The upper cover is generally connected with screws. The installation and removal of the screws cannot be separated from the use of a screwdriver, and there is a risk of slipping during the disassembly process. The convenience of use is average.
