Infini-cell: Optimum Li-ion Cell Interconnection For Large Scale EV Battery Packs
Pierric Gueguen, PhD, Global Business Development Director – Electric Vehicle, MERSEN
Infini-cell offers an optimum Li-ion cell interconnection for large scale EV battery packs. Unlike traditional battery interconnect solutions, laminated busbars offer ultra-thin, low weight and modular single layer Li-ion cell interconnection. Its thermal performance can support the increased utilization of larger cylindrical and prismatic Li-Ion cells. Its unique form factor enables a transition from Cu to Al interconnect, for reduced cost and weight at module and pack level. Combined with laser welding, Infini-cell assembly is more than four times faster than conventional wire/ribbon insertion and welding. Infini-cell bus bar is also a “smart” bus bar; it not only powers the battery cells but also monitors the temperature and voltage of battery cells as needed.
