Charging infrastructure power requirements for flexibility usage

Abstract

Scenarios with differently dimensioned charging capacity are examined with regard to the utilization of the flexibility potential of heavy commercial vehicles. These vehicles are only charged at the depot during idle times. The comparison of the scenarios illustrates how strongly the increase in flexibility potential depends on the dimensioning of the charging infrastructure. The lower extreme is determined by the size of the charging time window. If it is fully utilized, no flexibility can be achieved. A brief economic classification of the investment costs for charging infrastructure with the same number of charging points is given. It was shown, that economic obstacles exist for ascending the flexibility potential and incentives are required for counter-financing.
