Investigation of the potential to improve DC fast charging station economics by integrating photovoltaic power generation and/or local battery energy storage system

The economic feasibility of DC Fast Charging (DCFC) stations is strongly impacted by electricity charges, billed by electricity consumption (kWh) and power demand (kW), that have to be paid to the local utility. In this simulation study, the possibilities to significantly improve DCFC economics by reducing these utility charges have been investigated for DCFC stations assumed to be installed at highway service centres in Ontario and in Alberta (Canada).
