Public EV Charging Rates
Public EV charging rates generally differ significantly from home charging rates across different states in the U.S. Here’s a comparison:
Home Charging Rates
- Variation by State: Home charging rates vary based on residential electricity prices. For instance, in Washington, the rate can be as low as $0.11 per kWh, while in Hawaii, it reaches as high as $0.41 per kWh.
- Average Cost: The average U.S. residential electricity rate is around $0.16 per kWh, making it the cheapest option for EV charging.
- Example Cost: Charging 100 kWh (enough for a full charge in many EVs) could cost around $16 on average.
Public Charging Rates
- Type of Chargers: Public charging stations often use Level 2 or DC Fast Chargers. Level 2 chargers typically cost between $0.20 and $0.25 per kWh, while DC Fast Chargers can reach up to $0.60 per kWh.
- Variation by State: Rates vary by state and even within the same network. Generally, public charging is more expensive than home charging due to higher per unit costs and additional fees.
- Example Cost: A Level 2 charge costs between $0.20 and $0.25 per kWh, while DC Fast Charging is significantly more expensive, ranging up to $0.60 per kWh.
Comparative Analysis
| Charging Type | Cost per kWh | Cost per Mile | Annual Cost for 13,489 Miles |
|---|---|---|---|
| Home Charging | $0.16 | $0.04 to $0.05 | $506 to $720 |
| Level 2 Public | $0.20 to $0.25 | $0.06 to $0.08 | $770 to $963 |
| DC Fast Public | Up to $0.60 | $0.10 to $0.15 | $1,540 to $2,300 |
In summary, home charging is significantly cheaper than public charging due to lower residential electricity rates. Public charging, especially with rapid DC chargers, is more expensive due to higher costs and potential additional fees.
