Scalable cell connection technologies

The Inter-cell Connection Board (ICB), also commonly referred to as a Cell Contact System (CCS), provides an integrated electrical and mechanical interface for connecting and monitoring cells within an automotive battery module. The solution can be adapted to prismatic, pouch and cylindrical cell architectures, with copper or aluminum busbars and integrated high-voltage terminals supporting different battery power distribution requirements.

Multiple carrier technologies, including injection-molded plastic, blister structures and laminated foils, enable the ICB or CCS design to be optimized for specific module layouts and manufacturing processes. Sensing and monitoring functions can be integrated using Lear’s in-house FDC technology, Flexible Printed Circuits (FPC) or Flexible Flat Cables (FFC), supporting scalable battery module designs and efficient industrialization.
