The Combined Charging System (CCS) according to European and American standards allows charging with AC alternating current (socket or wallbox) as well as DC direct current (High Power Charging). Plugs and charging cables are always permanently installed on the charging station. The great advantage of the Combined Charging System: The "2-in-1" plug – called Combo 2 – consists of a classic type 2 vehicle coupling, which is supplemented by two additional DC contacts in the lower area. Electric cars can be charged with their Combo 2 connection as well as at the AC socket at home or at the DC quick charging station while on the move and thus use almost the entire charging infrastructure.
