Cell-to-pack batteries


Most EV battery packs are built from groups of cells housed in modules interconnected within a case that provides structural support, thermal management, environmental protection and connectivity with the rest of the drivetrain, but this is not the only way to do it. There are potential benefits to eliminating modules and building packs up from cells inside the case, in what has become known as the cell-to-pack arrangement. More…
