Abstract

This paper proposes the co-location of gas reciprocating generator sets with High Power Charging (HPC) stations for Battery Electric Vehicles (BEVs), to offer a low carbon source of heat and power which could help to meet national government transportation and heating strategies while minimizing the impact that HPC systems will have on the power network. Three different Combined Heat and Power (CHP) connection configurations are considered to determine the most fuel-efficient per forecasted utilization rates of the HPC station. The use of variable speed generators connected directly to the dc bus of the HPC station can offer improved fuel-efficiency performance compared to fixed speed, especially under part-loading conditions, however, the sizing of engine-generator sets based on expected utilization rates of the HPC station has the most influence on fuel efficiency.
