AI Technical Summary
Technical Problem
Existing cell structures have bottlenecks in terms of space utilization, assembly reliability, mechanical strength, and high-power performance coordination, especially showing obvious defects in high-capacity and high-rate fast charging scenarios.
Method used
The battery casing is designed with first and second protrusions at both ends to form an irregular structure. Combined with the design of the explosion-proof valve, this improves mechanical strength and space utilization, and optimizes the current path design.
Benefits of technology
It improves the space utilization and mechanical strength of individual battery cells, enhances safety and reliability, improves current path design, and improves the overall performance of the battery.
