Abstract:

The number of electric vehicles on the roads increases, so as modern innovations and ideas such as fast/super-fast charging and dynamic pricing are developed and implemented respectively. With those advancements on the rise, reservation of charging stations for electric vehicles will play a vital role in seamlessly integrating them into the transportation and mobility system. In this paper the authors derive basic requirements for building interoperable reservation systems and identify four generic approaches to reservation. For designing the system model and engineering the charging station reservation system, the authors utilize the E-Mobility Systems Architecture framework. For one of the reservation types, they implement a proof-of-concept and demonstrate its usefulness by conducting a showcase in Bavaria, Germany. Further, they set up and conduct a simulation-based evaluation to compare the four different reservation types regarding their benefit to users and providers as well as overall system efficiency. The results presented in this paper provide insights regarding the feasibility of the different reservation types under varying conditions.
