Features and Benefits


Manufacturers are looking for decreased labor time and reliable battery cell connections. Molex addresses this challenge through the FPC/PCB/FFC connectivity of the Volfinity system that eliminates the need for daisy-chain wiring. As a result, battery module customers can expect a more reliable solution from the FPC connection as it eliminates human errors in manual wired connections. Additionally, FPC connectivity is more resilient to degradation when compared to wires.

Commercial vehicle manufacturers need large, powerful batteries while simultaneously meeting weight requirements. The thermoplastic carrier, lamination and thermal forming in the Volfinity system are relatively lightweight while delivering a reliable connection through the high voltage sensing connection. As a result, the Volfinity system is an attractive solution for commercial vehicle designers who need to maximize battery capacity while keeping modules as light as possible.

Manufacturers also seek highly compact electrical connections which are addressed by the Volfinity Cell Contacting System. This system provides a space-optimized and integrated cell sensing board, which is designed to fit within tight spaces effectively. As a reliable electronic board solution, the Volfinity Cell Contacting System simplifies sourcing and enhances performance across applications such as energy storage systems, commercial vehicles and industrial applications.
