The interaction supported by these protocols consists of exchanging information ranging from authorization identifications (ID) to charge point locations, but also of sending commands for charging control. In this study, a selection of protocols encountered by ElaadNL is discussed. These protocols and the relation to the different roles in the EV market are visualized in the figure below: In the figure above many protocols are shown, even multiple occurrences of the same protocol between different roles are visible. At different locations, the use of different combinations of protocols were found, including a number of different protocols for similar functionality. From ElaadNL’s role as a knowledge and innovation center in the field of EV charging, this study aims to give more insight in a set of protocols that is currently in use in Europe and to clarify their relationship to the electricity grid. This study addresses the question which (set of) protocol(s) is best applicable for which functionality in different types of situations. To be able to do this, this study also identifies for each of these protocols which functionalities it supports and how it scores on interoperability, maturity, market adoption and openness.
