- DCAS - Department of Citywide Administrative Services
- DCFC - Direct Current Fast Charger
Purpose
Evaluate NYC DCAS' charging station infrastructure using utilization ratio and queue delay. Propose locations to upgrade Level 2 charging stations with additional DCFCs. The ultimate goal of this research is to assist NYC DCAS with implementing Mayor Bill de Blasio's 80 x 50 plan to reduce greenhouse gases 80% by 2050.
Motivation
Charging Time: According to ChargePoint, it takes 20-30 minutes for DCFCs and 4-6 hours for Level 2 chargers to fill up an 80-mile battery.
New York City Case Study - Base Scenario
1) Current EV Charging Station Infrastructure
- 567 total chargers - 563 Level 2 Chargers and 4 DCFCs
- 263 charging stations - 4 DCFC stations and 259 Level 2 charging stations
2) EV Parking Locations
Findings
Long access and charging times occur in Queens, midtown Manhattan, and Staten Island.
Conclusion
Select locations with high utilization ratio instead of high queue delay. Charging stations with less chargers have longer queue delays, so the queue delay strategy may identify small-scale charging stations at low-demand areas.
