About ISO 15118

ISO 15118 is a standard for Vehicle to grid (V2G) communication interface that defines how extended communication between vehicle* and charging station* should take place.

* Both the vehicle and the charging station must support ISO 15118.

 

ISO 15118

Is a standard for Vehicle to grid (V2G) communication interface that defines how extended communication between vehicle * and charging station * should take place.

Extended communication with EV over PLC + regular 12V PWM Pilot communication.

* Both the vehicle and the charging station must have ISO 15118 support

 

Plug & Charge

As the ISO 15118 communication interface allows for extended communication between the vehicle and the charging station, this makes it possible to identify the owner of the vehicle via the charging cable to start charging.

Plug & Charge uses multiple cryptographic mechanisms to ensure communication, and guarantees the confidentiality, integrity and authenticity of all exchanged transactions between the vehicle* , charging station* and payment operator *.

This means that the owner of the vehicle does not need to use the SMS, App, RFID or NFC charge card to identify himself against the charging station to confirm his identity in order to start charging.

* EV, charging station and payment operator must support ISO 15118 with Plug & Charge.
Today this feature is not enabled for use with Internal & External Authentication.


State of Charge (SoC)

Because the ISO 15118 communication interface allows extended communication between the vehicle and the charging station, this makes it possible to read out the desired energy (in kWh) from the electric vehicle. State of Charge (SoC) is defined only in DC-charging (Rapid charging).

So that the charging station* knows how much energy (in kWh) is needed for the battery pack to be charged, based on the vehicle* and / or what the user has set as battery settings.

* Both the vehicle and the charging station must support ISO 15118 with State of Charge.
Today this feature is not enabled for use with State of Charge.
