Development of Commercial EV Traffic Simulator Targeting Home Delivery

To realize a decarbonized society, the introduction of electric vehicles (EVs) is currently being promoted in the transportation sector. Commercial vehicles account for about 40% of CO2 emissions in the transport sector, so electrification of these vehicles is especially important for decarbonization. Although the number of commercial vehicles is small, the electricity consumption when converted into EVs is large because of the long mileage; thus, the CO2 reduction potential by charging from the renewable energy such as PVs is large. In this paper, we developed an EV traffic simulator for commercial vehicles, targeting the last one mile of home delivery, and evaluated the CO2 reduction effect by EV delivery vehicles. Through an analysis targeting the cities of Takasaki and Maebashi in Gunma Prefecture, we obtained the following findings: (1) Increasing the charger output alone had a limited effect on CO2 reduction, whereas combining a higher charger output with SOC control increased daytime charging and improved the CO2 reduction effect. (2) Combining a higher charger output, SOC control, and charging schedule management further enhanced the CO2 reduction effect. (3) By introducing a battery swap station, approximately 80% of the energy consumed for vehicle travel could be supplied by surplus PV electricity.
