Cell-to-Cell (C2C) Connectivity
Delivering scalable, customizable connectivity for tomorrow's EV battery architectures
Cell-to-cell (C2C) connectivity in EV batteries presents a range of challenges due to the diversity of cell shapes, sizes, and evolving chemistries. Each battery design brings unique layout, performance, and safety requirements, making one-size-fits-all solutions impractical.
Automakers must also navigate complex assembly processes, tight packaging constraints, and the need for reliable thermal and electrical performance. These factors, combined with increasing demands for cost -efficiency and scalability, make developing robust, manufacturable C2C systems a highly specialized and engineering-intensive task.
At TE Connectivity (TE), we collaborate with leading electric vehicle (EV) manufacturers and battery pack developers to design and manufacture next-generation C2C connectivity solutions. From early-stage design to full-scale production, we bring deep engineering, simulation, and process expertise for cylindrical and prismatic cell formats.
Our global capabilities span research, prototyping, and automated assembly, enabling flexible, cost-efficient system architectures. Whether you’re developing cell-to-pack designs or targeting optimized thermal, sensing, or weight outcomes, TE can help you move from concept to production faster and with greater confidence.
