GB/T The Guobiao standard 27930 for AC and DC charging was developed for charging

of Chinese EVs. As CHAdeMO, the communication takes place via CAN.

High Level Communication is specified in the ISO 15118 series as a bi-directional digital

communication using protocols, messages and physical and data link layers.

Load Leveling enables the prevention of overloading the charging infrastructure by calcu-

lating the maximum power that is distributed from the charging stations to the vehicles.

Plug and Charge Identification mode where the customer just has to plug his electric ve-

hicle into the EVSE and all aspects of authentication, authorization, load control and billing

are automatically taken care of with no further intervention from the customer.

Smart Charging The term smart charging is used for charging systems of electric or hybrid

vehicles according to ISO 15118, DIN SPEC 70121, SAE J2847/2. The communication

between vehicle and charging station is realized in two ways:

1) As powerline communication via the control pilot pin in the form of a PWM signal and a

digital signal for HomePlug-GreenPhy standard.

2) Wireless in case of inductive charging.

Value Added Services allow additional information, which is not directly needed for the

pure charging of the EV, to be exchanged via separate communication channels such as

HTTP, HTTPS, FTP. The to-date most prevalent VAS is the Preconditioning of buses, which

is standardized by VDV261.
