The cost to charge an electric car varies widely depending on where and how you charge it, as well as local electricity rates and the vehicle's battery size and efficiency.

Charging at Home

• In the United States, charging an EV at home typically costs about $1 to $1.50 per day if driving under 40 miles daily, or around $56 per month for 1,000 miles driven at 3 miles per kWh efficiency, with average electricity rates near 17 cents per kWh

• In the UK, home charging costs about £13 for a full charge of a typical 60 kWh battery EV, using electricity priced around 24.5p per kWh

• Using specialized EV tariffs with lower off-peak rates can reduce costs significantly, for example, to as low as 7p per kWh in the UK, cutting the cost per 10,000 miles to about £162

Public Charging

• Public Level 2 chargers in the US cost roughly $1 to $5 per hour, translating to about $0.20 to $0.25 per kWh, with a full charge on a 40 kWh battery costing $8 to $10

• Fast DC public chargers cost more, about $0.40 to $0.60 per kWh, with full charges ranging from $10 to $30

• In Germany, prices for public charging vary by speed: standard charging costs €0.29 to €0.45 per kWh, fast charging €0.40 to €0.60 per kWh, and ultra-fast charging €0.69 to €0.89 per kWh

• In the UK, public chargers typically cost £0.60 to £0.90 per kWh, making a full charge around £28 to £54 depending on time and charger speed

Summary

• Home charging is generally the cheapest and most convenient option, costing roughly $0.13 to $0.17 per kWh in the US and about £0.13 to £0.25 per kWh in the UK.
• Public charging is more expensive, especially fast chargers, which can cost two to three times more than home charging.
• Costs depend on electricity prices, charging speed, and vehicle efficiency.

Thus, charging an electric car can cost anywhere from a few dollars or pounds for a full charge at home to $10–$30 or £20–£50 at public fast chargers, with exact costs depending on local rates and charger types
