How much does it cost to charge an EV at home?

Charging a typical 75 kWh EV at home from 20% to 80% costs about $7-$9 at the US average residential electricity rate of $0.16/kWh. That works out to roughly $0.04-$0.05 per mile of driving, or about $30-$50 per month for the average commuter. Off-peak rates can lower this further.

Is it cheaper to charge at home or at a public station?

Home charging is almost always cheaper. Residential electricity averages $0.16/kWh, while public Level 2 stations charge $0.30-$0.50/kWh and DC fast chargers run $0.40-$0.60/kWh. A full charge at home might cost $9, while the same charge on a DC fast charger can cost $25-$35.

How long does it take to fully charge an EV?

Charge time depends on the charger speed and battery size. A 75 kWh EV takes about 50+ hours on Level 1 (120V), 8-10 hours on Level 2 (7.2 kW), 60-90 minutes on a 50 kW DC fast charger, and 20-30 minutes on a Tesla Supercharger from 20% to 80%.

What is the cost per mile for an electric car?

Electric cars cost about $0.04-$0.05 per mile at home electricity rates and a typical 3.5 mi/kWh efficiency. Public DC fast charging can push that to $0.12-$0.17 per mile. Compared to a 25 mpg gas car at $3.50/gallon, that is about $0.14 per mile, so EVs typically save 60-70% on fuel.

How much does Tesla Supercharging cost per kWh?

Tesla Supercharging costs roughly $0.30-$0.50 per kWh depending on location, time of day, and demand. Urban Superchargers tend to run higher than rural ones, and idle/congestion fees apply when stalls are busy. Tesla owners with home charging typically Supercharge only on road trips.
