AI Technical Summary

Technical Problem

Existing air-cooled battery packs have poor heat dissipation, low space utilization, and the battery terminals obstruct airflow, leading to a sharp drop in electrical performance.

Method used

The battery cells are placed along the X or Y axis, and the air blows towards the battery cells from the Z axis. The enclosure is designed with top air intake and bottom air intake. Combined with the close-fitting layout of the module frame and fan, a stable and efficient convection air duct system is formed. A 2mm gap is maintained between the battery cells. The enclosure is made of aluminum alloy or carbon fiber composite material, and the filter screen prevents impurities from entering.

Benefits of technology

It significantly improves the contact area and heat exchange efficiency between the battery cell and the cooling air, resulting in better temperature uniformity, reducing the risk of battery overheating, improving space utilization and heat dissipation efficiency, and reducing material costs and assembly difficulty.
