Using OCPP with CHAdeMO

A CHAdeMO charging station “speaks” CHAdeMO to the electric vehicle and OCPP to the charging station management system. How do they relate to each other?

This whitepaper has been written by Open Charge Alliance together with the CHAdeMO Association to show how these protocols work together to charge a vehicle. It provides a translation table for the terminology used in both protocols and a set of diagrams that show the exchange of messages between electric vehicle and charging station on the one hand and charging station and management system on the other hand.

It also explains how information from CHAdeMO about the DC charging session in progress can be made available to a charging station management system via the OCPP 2.x device model functionality.
