CTP(Cell to Pack, Cell battery pack) is changing from the exclusive technology of the top cell enterprises to the general proposition of the entire PACK industry.

In June, 2026,, chuneng New Energy won the SNEC energy storage technology excellence award for "modular integration technology (CTP3.0). This technology subverts the traditional three-level structure of battery Pack "battery-module-battery Pack", directly integrates the battery into the system Pack level, with a single package volume density of 280Wh/L and rated energy of 195.68kWh, battery pack the number of production processes is reduced by 35% compared with the traditional solution, and the production line beat is increased to more than 60..

At the same time, SK On disclosed the CTP integrated package solution for the first time On InterBattery 2026, covering three forms: soft package CTP, soft package-square integrated package and large surface cooling CTP, among them, the soft package CTP directly integrates cell into battery pack by eliminating modules, and aims to realize commercial production in 2027.. Zero-running cars have achieved the world's first mass production without battery pack CTC technology. CTC can increase the torsional rigidity of the car body by 25% and the battery layout space by 14.5%..

The change brought by CTP technology is not only the lack of a "module" part. For PACK factory, it means systematic reconstruction of production line process: cell the feeding accuracy is higher, because FTTx straight cell does not have modules to buffer; The process window of laser welding is narrower, because the spacing between cell is more compact than the module solution; The thermal management solution needs to be redesigned because the traditional module-level thermal diffusion isolation structure is canceled.

Dongguan Juneng New Energy Technology Co., Ltd. is equipped with full-automatic laser welding equipment and AI visual inspection system in the manufacturing base, covering cell key processes such as feeding, scanning code, gluing inspection, welding quality inspection, etc, upload all process data to the MES system for tracing the entire process. The incoming inspection process performs full inspection and capacity separation for cell, and the capacity deviation is controlled within 1%. The company's flexible manufacturing system can adapt to the rapid transformation needs of many varieties and small batches, from T-bar scooter battery of 2.7kg to 132kg of household energy storage batteries. The same production line can be switched within several hours.

For equipment manufacturers who are evaluating the feasibility of CTP solutions, when choosing PACK Partners, a pragmatic judgment criterion is: whether the other party has the production line adaptation capability of switching from traditional module solutions to CTP solutions, and whether the laser welding precision and on-line detection capability can meet the technological requirements of CTP production line.
