Trackwise of Tewkesbury, the PCB-based products developer, is building a high volume plant for one of their key battery sub-systems – the cell-to-pack interconnect.

Trackwise is currently delivering lightweight, space-saving, flexible printed circuit (FPC) interconnect technology to the automotive industry to facilitate high power density cell-to-pack battery systems for electric vehicles (EV).

Cell-to-pack technology aims to increase battery pack power density by directly integrating cells into a battery pack, eliminating the modules commonly used in most current pack designs.

Many major EV companies, including Tesla, Hyundai and Volvo, plus CATL and other battery producers, have recently issued press releases or statements referring to cell-to-pack battery programs.

Other approaches, such as cell-to body and cell-to-vehicle, deliver similar benefits.

Trackwise’s FPC technology is used to connect the cells in the batteries, saving space and weight over traditional wiring looms.

The cell-to-pack FPCs are also very reliable, and, because they are constructed using a printing process, they are very repeatable.

They are also simple to install and can include components mounted on both sides for extra processing and monitoring for temperature and voltage control.
