BMW has selected the Molex Volfinity Cell Contacting System (CCS) for series production of battery packs in its next-generation electric vehicles (EV).

In development since 2018, Volfinity connects cells to the control board in an electric vehicle battery module, eliminating the need for daisy-chained wires. The system supports integrated cell sensing features, cell monitoring and balancing, and temperature measurement functions, all designed to meet BMW’s functional safety requirements.

Molex used in-house and partner design and production expertise to develop its deep cell contacting system three years ahead of competitive interconnect suppliers through direct collaboration with plug-in hybrid EV and traditional EV makers, energy storage OEMs, and battery cell and battery pack suppliers.

“Molex’s cell contacting system award is a testament to BMW Group’s commitment to driving comparative advantage through engineering innovation in the EV space,” said Steve Drysdale, VP and general manager, Molex Micro Solutions Business Unit.

“Our global teams located in Singapore, China and Germany served as an extension of the BMW Group’s engineering teams, collaborating around-the-clock to provide rapid design iteration and problem resolution to innovate Volfinity to meet BMW Group’s unique requirements. Our dedication to the innovation process resulted in a transformational interconnect solution for the BMW Group, and we are thrilled to be chosen.”
