CCS (Combined Charging System)

CCS (Combined Charging System)

These charging sockets combine the inlets for both AC and DC using shared communication pins.  CCS1 and CCS2 share the design of the DC pins as well as the communications protocols.  These are widely used in Americas & Europe.

CCS1 and CCS2 share the design of the DC pins as well as the communications protocols, therefore it is a simple option for manufacturers to swap the AC plug section for Type 1 in the US and (potentially) Japan for Type 2 for other markets.

It is worth noting that to initiate and control charging, CCS uses PLC (Power Line Communication) as the communication method with the car, which is the system used for power grid communications.

This makes it easy for the vehicle to communicate with the grid as a ‘smart appliance’.
