2023 CCS Integrated Busbar Industry for New Energy Batteries

CCS (Cells Contact System), also known as a wiring harness board integrated component, is composed of signal acquisition components (wiring harness/FPC/FFC, etc.), plastic structural components, copper aluminum bars, etc. connected into a whole through processes such as hot pressing or riveting, to achieve high-voltage series parallel connection of battery cells, as well as temperature sampling and voltage sampling functions of battery cells. It is part of the BMS system and can be used in fields such as new energy power batteries and energy storage batteries.

With the rapid development of industries such as new energy vehicles and energy storage, the CCS integrated busbar market has also rapidly expanded. At the same time, with the advancement of battery integration technology and the increasing demand for automation in large-scale production, traditional wire harness solutions such as CCS are gradually being replaced by integrated and lightweight FPC solutions. In addition, compared to the FPC scheme, the more cost-effective FFC and FDC schemes are also being continuously promoted.

The traditional solution of using wire harnesses and injection molded brackets has lower costs and better stability, but requires manual assembly and low automation, which is not conducive to large-scale production; Compared with the wiring harness scheme, CCS integrated busbars using FPC/MFC and other vacuum formed boards, or hot pressing schemes, have a lightweight and regular structure with high integration, which is conducive to improving the space utilization and assembly efficiency of battery packs. They are in line with the trend of automotive lightweighting, component system integration, and large module assembly, and have been widely used in the products of mainstream battery manufacturers such as CATL, BYD, Guoxuan High tech, and AVIC Xinchuang.

The rising sales of new energy vehicles have driven the rapid development of the FPC/CCS market, and due to the higher added value of CCS compared to pure FPC, many FPC/PCB manufacturers have further laid out downstream integrated products CCS. Some institutions predict that the global and domestic FPC market space for new energy vehicle power batteries is expected to reach 6.4-10.8 billion yuan and 3.2-5.4 billion yuan respectively by 2025, and the global and domestic CCS market space for new energy vehicle power batteries is expected to reach 16-27 billion yuan and 8-13.5 billion yuan respectively by 2025.
