AI Technical Summary

Technical Problem

CTP battery pack modules suffer from uneven extrusion force and inconsistent compression due to inconsistent cell thickness. This makes it difficult to align the aluminum core and FPC, and the battery system has a large width, making it unsuitable for platform-based products and unable to achieve production capacity advantages.

Method used

A single-module CTP battery housing is designed, employing structures such as reinforcing ribs, reinforcing plates, raised ribs, and insulating sheets to ensure cell fixation and insulation. Combined with a sealing plate and an exhaust valve, it achieves stable cell installation and safety protection.

Benefits of technology

It achieves stable fixation and insulation of the battery cells, avoids the problem of excessively wide battery systems, is suitable for platform-based products, enables quick replacement of faulty modules, reduces customer losses, and meets IP67 sealing requirements.
