AI Technical Summary

Technical Problem

As the energy storage capacity of energy storage systems increases, it becomes difficult for protective plates to fit well with the charged areas of the battery cells, affecting the protective effect. Furthermore, the installation of large-size protective plates becomes more difficult, they are more easily damaged, and pose a higher transportation risk.

Method used

The design employs multiple protective plates that are sequentially sealed and connected along the length direction. The live area of ​​the battery cell assembly is covered by the spliced ​​protective components, reducing the length of each protective plate and facilitating a good fit with the battery cell assembly. The sealing and stability are ensured through connectors and seals.

Benefits of technology

It improves protective performance, reduces the risk of damage during installation and transportation, extends the service life of the protective plate, adapts to different cell pack sizes and shapes, and reduces replacement and maintenance costs.

Abstract

The application provides a battery pack and an energy storage system. The battery pack comprises a battery cell group and a protection assembly used for covering a live area of the battery cell group. The protection assembly comprises a plurality of protection plates which can be sealed and docked in sequence along a length direction. The protection assembly comprises a plurality of protection plates which can be sealed and docked in sequence along a length direction. That is, the length of each protection plate is reduced through the splicing design of the plurality of protection plates, the protection plates are better matched with the live area of the battery cell group, and the protection performance is improved.
