What drives the cost

A Level 2 home charger typically delivers 7.2 kW, adding roughly 25-30 miles of range per hour. Because you're buying a known quantity of energy, EV charging cost is unusually predictable: it's essentially your car's kWh-per-mile times your rate. Most drivers charge a few hours a night rather than continuously.

Questions

How much does it cost to charge an electric car at home?

A typical EV uses about 0.3 kWh per mile, so 1,000 miles a month is roughly 300 kWh. Multiply that by your rate — the state table below shows what that works out to where you live.

Is charging at home cheaper than a public charger?

Almost always. Public DC fast charging commonly costs two to three times the residential rate per kWh, plus session fees.

How do you calculate what a Level 2 EV charger costs to run?

Multiply its wattage by the hours it runs per day, divide by 1,000 to get kilowatt-hours, then multiply by your electricity rate. For a Level 2 EV charger: 7,200 W × 2 h ÷ 1,000 = 14.40 kWh per day, which at 19.4¢/kWh is $2.80 per day.

How many watts does a Level 2 EV charger use?

Typically 7,200 watts, with most models falling between 3,800 and 11,500 watts. The label on the appliance or its power supply gives the figure for your specific unit.
