ISO 15118
Vehicle-to-charger communication and plug-and-charge
What it is, and how we use it
ISO 15118 allows a vehicle and a charger to authenticate each other using certificates, so a driver simply plugs in and the session is authorised and billed without a card, app or QR code.
The prerequisite on the platform side is OCPP 2.0.1, which carries the certificate-handling messages — that part is in place. The remaining work is contract certificate management and the hardware to support it in the field.
If plug-and-charge is on your roadmap, specify OCPP 2.0.1 and ISO 15118 capability on new hardware purchase orders now, even though neither is in use yet.

The link between every charger and the platform. Both versions run side by side behind one operational surface.
SupportedOCPI
The link between platforms. Publish your network to roaming partners, and let your drivers charge on theirs.
