Question 1

How much does it cost to charge an electric car?

Accepted Answer

The cost depends on your battery size, electricity price, and how much you charge. For a typical 60 kWh battery at $0.15/kWh, a full charge costs about $9. At home, charging usually costs 3-5x less per mile than petrol.

Question 2

How is EV charging cost calculated?

Accepted Answer

Cost = battery capacity (kWh) × electricity price ($/kWh) × (end charge % - start charge %). To get cost per mile or km, divide the cost by the range added. This calculator handles all of that and compares it to petrol.

Question 3

Is charging an EV cheaper than petrol?

Accepted Answer

In most regions yes. Home charging at off-peak rates is typically 60-80% cheaper per mile than petrol. Public fast chargers are more expensive but usually still cheaper than fuel. Savings depend on local electricity and fuel prices.

Question 4

What is the difference between kWh and miles of range?

Accepted Answer

kWh is the amount of energy stored in the battery. Miles (or km) of range is how far that energy takes you, which depends on efficiency (miles per kWh). Most EVs achieve 3-4 miles (5-6.5 km) per kWh in normal driving.
