Description

Technical Field

CTP is an integrated battery. The traditional power battery pack is assembled from cells (Ce ll) into modules (Module), and then the modules are installed in the PACK box to form a three-level assembly mode. The CTP technology skips the standardized module link and directly integrates the cells on the PACK box to form a CTP module, eliminating the intermediate module section and effectively improving space utilization and energy density.

[0003] However, the conventional box-entering fixture is a simple mechanical clamp that is only applicable to battery modules of specific specifications and cannot perform box-entering operations on new CTP modules. In addition, the conventional box-entering fixture is prone to damage the battery module when clamping the battery module.
