[Cutting-Edge Technology] ANWHA’s innovative technology provides a comprehensive solution for CTP power battery production lines.
2022-10-18
Recently, ANWHA (Shanghai) Automation Engineering Co., Ltd. delivered a highly integrated CTP power battery production line to an international brand customer. Leveraging its independently developed innovative technologies, the company has boosted production efficiency, reduced product costs, and enhanced product quality, earning high praise from the client.
What is CTP?
CTP (Cell-to-Pack) is a structural innovation in power battery packaging. As one of the three major components of new-energy vehicles, power batteries continue to undergo groundbreaking innovations and iterative upgrades, with an ever‑growing array of system‑level architectural breakthroughs such as CTP, CTC, and CTB, which in turn drive the integration and consolidation of their manufacturing processes.
Compared with conventional battery packs, CTP eliminates the module‑level design and directly integrates the cells into the pack, enabling more vehicle models—especially those with limited underbody space—to further increase battery capacity. At the same time, CTP battery packs reduce the number of components by 40%, boost energy density by 10%–15%, and improve production efficiency by 50%, making it a key focus of innovation in power‑battery architecture.
This time, ANWHA Company delivered a highly integrated CTP power battery production line that achieves full-line automation, addresses the pain points of cell insertion and welding, and enables flexible mixed-model production.
1. The overall automation rate reaches as high as 95%.
ANWHA’s technical solution has achieved full-line automation, with an automation rate exceeding 95%. By leveraging a self-developed MES system, it ensures product information traceability, significantly boosting production efficiency, reducing labor costs, and enhancing the stability of product quality.
2. Independently developed solutions to address technical challenges
During the module-in-box process, ANWHA addressed multiple technical challenges—including precise box insertion, drop‑proof handling, and seamless box alignment—through innovative technologies and optimized processes. At the same time, in the BUSBAR welding process, it overcame persistent issues such as weld spatter, achieving rigorous quality control and robust safety protection throughout the welding operation.
3. High flexibility enables mixed-model production.
ANWHA’s CTP highly integrated battery production line employs an automated adhesive‑applying process, equipped with a vision inspection system and a product quality testing system. It boasts high flexibility, enabling mixed‑flow production of single- and double-row cell packs.
In the coming years, CTP will become the mainstream battery system design approach. ANWHA has mastered the key technologies for high-integration CTP power battery production lines and possesses extensive experience in implementing CTP projects, enabling it to provide more efficient end-to-end solutions to automakers and battery manufacturers, thereby helping its customers achieve success.
