Busbars and interconnects

Large EV battery packs can contain thousands of cells that have to be connected to form modules and packs, then connected via busbars to other driveline components such as inverters and DC-DC converters to make robust and reliable connections quickly and efficiently in confined spaces while keeping costs down. That has made...
