DC Fast Charging (DCFC) and Level 2 charging differ significantly in both upfront installation costs and per-kWh charging fees:
Cost per kWh Comparison
- DC Fast Charging:
- $0.40–$0.60 per kWh for commercial stations, translating to $10–$30 per full charge for a typical EV battery.
- Exclusively using DCFC for 13,489 annual miles costs $1,540–$2,300/year.
- Level 2 Public Charging:
- $0.20–$0.25 per kWh, totaling $8–$10 per full charge for a 40 kWh battery.
- Annual costs for the same mileage range $770–$963.
Installation & Infrastructure Costs
- DC Fast Chargers:
- $20,000–$100,000 per unit, with additional costs for high-power electrical infrastructure.
- Level 2 Chargers:
- $500–$5,000 per unit, making them a cost-effective choice for home or fleet installations.
Operational Considerations
- Speed: DCFC charges EVs in 30–60 minutes, while Level 2 chargers require overnight sessions for full capacity.
- Usage Scenarios:
- DCFC is ideal for highway stops or commercial fleets needing rapid turnaround.
- Level 2 suits workplaces, residential areas, and fleets with predictable downtime.
For most drivers, Level 2 charging at home (when available) remains the cheapest long-term option, while DCFC provides premium convenience at a higher cost.
