Battery interconnect systems customise battery modules

Technology introduced by Interplex is claimed to streamline the design and manufacturing of robust interconnects for battery modules across a range of industries.

The Cell-PLX custom battery interconnect system connects battery cells to current collectors and a customisable lead frame interface to the battery management system. While battery module designs vary according to manufacturer and specific applications, for electric vehicles (EVs) and automotive power applications, land and maritime transportation, or wind energy storage, all require robust mechanical and electrical interconnect systems to integrate and interface with the array of battery module cells.

Cell-PLX effectively handles the increasing variety of battery module sizes and configurations. Craig Kennedy, product portfolio director for battery interconnect systems, said: “Cell-PLX™ is customisable to specific application designs. It supports various current density requirements, with single or multi-layered current collectors and dielectric layers of different thicknesses.”

Explaining how the company has developed the Cell-PLX, he explained: “With our advanced high-speed manufacturing processes, cell connection terminals on the current collector can be made thinner than the current collector itself. This assures a reliable weld joint to the battery cells while maintaining minimum current density requirements.”

Cell-PLX enables optimal positioning for mating with battery cells, improving connection quality and reliability, Interplex says. The modular nature of the system also allows for passive and active component placement, including fuses, thermistors, most positive and negative interconnects, cell holder designs, signal interconnects and harnesses or circuits connecting to the control board.

Interplex customises mission-critical interconnects and specialised high-precision products across the automotive, datacomms and telecomms, medical and life sciences and aerospace industries.

The company has over 60 years’ of expertise in design, develop and production. The company operates in 30 locations across 14 countries.
