When many electric vehicles need to be charged at the same time, load management plays a crucial role to avoid load peaks. However, the load management algorithm requires a lot of different information sources to calculate the optimal set of charging profiles.
In some scenarios the information which vehicle is connected to which charging station is mandatory. If there is a authorization process related to the vehicle the identity of the vehicle is already available.
If there is no authorization used, the identification of the vehicle is not possible.
As a solution, we will describe possible methods for the identification of a vehicle with OCPP.
A method if supported by both charging stations and charging station management systems that ensures interoperability without any further project-specific adaptations.
