Battery packs powering current electric vehicles have rapidly evolved over time, transitioning from “Ctm” (Cell to Module) configurations to “Ctp” (Cell to Pack) and “Ctb” (Cell to Body). The next step is the “Ctc” (Cell to Chassis) configurations. While battery manufacturers work to create groups with increasingly higher performance, car manufacturers are also looking in the same direction, seeking to directly integrate batteries into the chassis of their vehicles. It should be noted that a battery pack normally consists of multiple cells integrated into a single module. By combining multiple…
