A generic EV charging model extracted from real charging behaviour

To capture reliable information about the existing flexibility potential of electric vehicles forecasts of charging processes are required in order to allow of utilization and management of available flexibility. Measurements of vehicles from different manufacturers show a heterogeneous behaviour of charging characteristics and charging characteristic switching points when connected to 11 kW charging stations. This paper analyzes the relationship between vehicle-specific easy to identify parameters and the charging characteristics. The proposed generic model is able to capture different charging characteristics with only a small set of parameters, to generate vehicle-specific forecast profiles.
