ENNOVI has launched the ENNOVI-CellConnect-Prism, a groundbreaking prismatic battery cell contacting system developed to redefine the connectivity and efficiency of battery modules.
The system empowers engineers with unparalleled flexibility, allowing the seamless integration of individual prismatic cells to create larger battery modules or advanced cell-to-pack (CTP) and cell-to-chassis (CTC) configurations. Streamlining the assembly process and eradicating inefficiencies accelerates battery pack production while optimising material usage and reducing costs.
Randy Tan, product portfolio director for Battery Platform Development Solutions, ENNOVI, explains, “Traditionally, prismatic cell contacting systems have relied on current collector assembly (CCA) technologies, which often suffer from inherent inefficiencies. These systems entail complex processes, including laminating and assembling carriers with low-voltage data collection circuits, current collectors, and terminal busbars. However, ENNOVI-CellConnect-Prism revolutionises this approach by introducing innovative features that enhance performance and sustainability.”
One of the key innovations of the system is the adoption of a die-cut circuit as an alternative to the conventional FPC. This reel-to-reel process reduces production time and costs while minimising environmental impact. Also, using automotive-grade PET material and hot-bar soldering ensures optimal thermal resistance and component attachment without compromising integrity.
Furthermore, the system eradicates the necessity for traditional insulation methods by integrating voltage and temperature sensing directly into the assembly. This approach optimises material usage and production efficiency while maintaining the highest reliability and safety standards.
The company’s patent-pending ENNOVI-CellConnect system represents a paradigm shift in battery interconnect technology, empowering OEMs and gigafactories to scale production and fulfil the increasing demand for electrified mobility solutions. This versatile platform offers unique customisation options for diverse applications and is compatible with prismatic, cylindrical, and pouch cell formats.
