AI Technical Summary

Technical Problem

The heat dissipation of existing battery packs is uneven, especially at the connection between the top of the cells and the busbar, which affects the performance and safety of the battery pack.

Method used

The design employs multiple liquid cooling plates, including a first liquid cooling plate that directly contacts the busbar for cooling, and a second liquid cooling plate that is attached to both sides of the battery cell. These plates are connected by a connecting pipe to form a complete liquid cooling circulation system, ensuring uniform cooling of the key heat-generating parts and sides of the battery cell.

Benefits of technology

It significantly improves the cooling effect and uniformity of the battery cells, extends the service life of the battery pack, and enhances overall performance and safety.
