Interplex has expanded its portfolio of interconnect solutions for EV batteries. The company’s Cell-PLX interconnect solutions are suitable for battery modules based on cylindrical and standard prismatic cells, and now it has released a new version that’s specifically optimized for next-generation prismatic cells.

Compliant with USCAR 2-6 automotive performance requirements, the Cell-PLX interconnect platform provides the data transfer capabilities needed for constant monitoring of voltage and temperature parameters, and supports battery module voltages from 12 V to over 800 V. Interplex says it can be adapted to suit any battery shape or size, including battery modules consisting of thousands of cells.

The company says its new Cell-PLX offering supports not only conventional prismatic cells in plastic carriers, but also the higher-density laminated-type prismatic cells that EV OEMs are now starting to specify for their batteries.

The new interconnect solutions can handle current densities up to 15 A/mm². They can be supplied with a choice of either aluminum or copper current-collecting layers, each accompanied by a UL 94-rated dielectric insulation layer. Plastic or metal housing options are available.

Cell-PLX is part of an expansive lineup of EV battery components (which also includes battery module enclosures, cooling plates, busbars and more). Interplex says its comprehensive vertical integration—stamping and molding, assembly (including laser and ultrasonic welding) and testing are all done in-house—enables it to offers its customers truly differentiated products.

“Incorporating laminated-type prismatic cells into EV batteries will mean larger amounts of energy can be stored within a more compact space. This is clearly advantageous, leading to battery modules that have tighter dimensions and are more lightweight,” Randy Tan, Product Portfolio Director for Energy, Interconnects at Interplex, explains. “Having an interconnect technology that is purposely aligned with these cells is vital. This should provide superior signal integrity alongside sufficient insulation. Now, with the newly-released Cell-PLX interconnect systems, we are well positioned to serve automotive OEMs looking to utilize laminated-type prismatic cells in their batteries.”
