Characterize the Demand and Energy Characteristics of Direct Current Fast Chargers
- Idaho National Lab. (INL), Idaho Falls, ID (United States)
The electric vehicle supply equipment (EVSE) deployed by The EV Project included both AC Level 2 (ACL2) and DCFC units. Over 100 of the Blink dual-port DCFCs were deployed by The EV Project. These DCFCs were all publicly accessible, located in workplaces, near traffic hubs, retail centers, parking lots, restaurants, and similar locations. The Blink DCFC dual-port design sequences the charge from one port to the other, delivering power to only one of two vehicles connected at a time. The actual power delivered through a port is determined by the PEV’s on-board battery management system (BMS).The Blink DCFC is capable of charging at power up to 60 kW. For the EV Project, the Nissan Leaf was the only participating PEV capable of accepting a DC charge. The Nissan Leaf BMS allows acceptance of up to 50 kW DC power. At this rate, the DCFC is capable of recharging a Leaf battery from a 30% state of charge (SOC) to an 80% SOC in about 25 minutes. The power required by the DCFC to recharge a plug-in electric vehicle (PEV) can be a significant additional electrical load for the charging site host and contributes to the overall power demand on the electric grid.
