Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, and in particular to a high-density battery structure. Background Technology
[0002] With the deepening development of new energy industries such as energy storage, photovoltaics, and wind power, various new energy sources are integrating to form complementary energy stations. Currently, existing UPS battery pack structures typically require 30 battery cells and a protection board. However, due to the large size of the protection board, existing chassis cannot accommodate 30 battery cells and the protection board simultaneously. Furthermore, the complex chassis structure makes disassembly and installation difficult, resulting in high overall product cost. Limited space and the lack of internal airflow, coupled with poor fan placement, lead to high temperature rises in the battery cells during charging and discharging. This increases the risk of thermal runaway within the chassis, potentially causing heat propagation and fires, posing a significant safety hazard. Additionally, the rapid temperature increase of the battery cells during high-rate discharge also reduces their lifespan. Utility Model Content
