Intelligent Multi-Vehicle DC/DC Charging using an Active Response Management (ARM)

This paper deals with the major challenge of an efficient load management of electric vehicle charging infrastructure. Therefore, a smart DC/DC charging station with four vehicle access points and an intelligent assignment algorithm is developed as a part of a government-funded research project applied in Solingen (Germany). On the one hand, the charging station is able to deal with a temporal volatile energy supply based on the connection to Solingens DC catenary grid and its main utilization by the over-headline buses. On the other hand, an active response management will intervene in the future to react on fluctuating charge current acceptance (CCA) to avoid underutilizations.
