Ethernet-based communication is supported according to ISO 15118, DIN SPEC 70121 and SAE J2847/2. This so called Combined Charging System (CCS) is common in North America and Europe. For all vehicle manufacturers, AC and DC charging is supported with the profiles EIM (External Identification Means) and PnC (Plug' n Charge) including SLAC (Signal Level Attenuation Characterization). In addition, Value Added Services (VAS) can be connected via HTTP and DNS, for example, or OEM-specific functions can be implemented. This could be, for example, a parallel, proprietary communication between the vehicle and the charging station in order to exchange additional information.
