AI Technical Summary

Technical Problem

Soft-pack lithium batteries are unstable when placed inside fireproof and heat-insulating structures, and are easily deformed and damaged by vibration, lacking effective protective measures.

Method used

The fireproof and heat-insulating structure adopts a double-layer structure, including an inner box, inner cover, inner frame, compression spring and top plug. Combined with the design of outer box, outer cover and clamping feet, it can achieve stable placement and multi-layer protection of soft-pack lithium batteries. The compression spring buffers and absorbs shock, and the clamping feet position and stack the batteries.

Benefits of technology

It enables the stable placement of soft-pack lithium batteries within a fireproof and heat-insulating structure, reducing deformation and damage, and facilitating stacking and transportation.
