How to identify two types of CCS

Also referred to as a battery cover, the Cell Connection System (CCS) is used in electric vehicles (EV) and hybrid electric vehicles (HEV). Used as the top cover to the battery pack, it provides temperature sensing and voltage sensing of the battery cells and high voltage connectivity, via the busbars, across the battery pack/cells. Its sensing capabilities allow the OEM to connect the sensor to the battery management system (BMS), which supports monitoring / controlling the state of charge for the battery pack/cells.
