ENNOVI, an e-mobility technology provider, has recently introduced a new cell contacting system called ENNOVI-CellConnect-Pouch for battery manufacturers utilizing the pouch cell form factor. This system is designed to enhance the structural integrity and durability of battery packs by utilizing flexible die-cut circuit (FDC) technology for low-voltage signal traces, resulting in reduced production time and costs. The upper dielectric layer of the system incorporates FDC copper traces, while the lower layer is pre-cut to the shape of the current collectors, both made of automotive-grade PI or PET material known for its electrical insulation and temperature stability properties. The overall design of the system aims to mitigate battery thermal runaway by achieving a fast exhaust release time.
Gustavo Cibrian, Product Manager at ENNOVI, highlighted that the ENNOVI-CellConnect-Pouch cell contacting system provides battery manufacturers with a vertically integrated production solution that enables the production of parts at a lower cycle time using hot lamination. The design of the system eliminates the need for traditional plastic cell carriers typically made from glass-reinforced plastic, therefore eliminating the carrier storage and molding lines, as well as the heat staking process. By streamlining material usage and creating a thin design, the system incorporates built-in fuse traces, surface mount fuses, and NTC temperature sensors within the two layers of the system, further enhancing its efficiency.
Utilizing the ENNOVI-CellConnect-Pouch system allows for the consolidation of various components and functionalities within the battery cell contacting system, providing a more efficient and cost-effective solution for battery manufacturers. This system is particularly beneficial for companies utilizing the pouch cell form factor, as it enhances the overall structural integrity and durability of battery packs while reducing production time and costs. The lamination technology employed by ENNOVI ensures the quality and reliability of the cell contacting system, contributing to the overall performance and safety of battery packs in electric vehicles and other applications.
By incorporating flexible die-cut circuit (FDC) technology for the low-voltage signal traces within the ENNOVI-CellConnect-Pouch system, battery manufacturers can achieve a streamlined production process that reduces both time and costs associated with traditional methods. The use of automotive-grade materials such as PI or PET ensures the electrical insulation and temperature stability of the system, further enhancing its reliability and performance. Additionally, the integrated design of the system helps to mitigate the risks of battery thermal runaway by achieving a fast exhaust release time, contributing to the safety and longevity of battery packs in electric vehicles.
Overall, the introduction of the ENNOVI-CellConnect-Pouch cell contacting system signifies a significant advancement in battery pack technology, particularly for manufacturers utilizing the pouch cell form factor. With its innovative design, streamlined production process, and focus on safety and efficiency, this system offers a comprehensive solution for enhancing the performance and durability of battery packs in various applications. ENNOVI continues to drive innovation in e-mobility technology, providing industry-leading solutions that meet the evolving needs of the electric vehicle market and beyond.
