Charging an electric car at home adds a big new load — a Level 2 charger delivers around 7,000W, and a typical overnight charge runs a few hours. That can add roughly 200–400 kWh a month for an average commute, which often becomes the single largest item on the electric bill (while replacing a much larger gasoline bill).
Because charging is flexible — the car sits plugged in for hours — it's the perfect load to shift to cheap overnight rates, which is where the real savings live.
What drives the cost of running an EV charger
- Miles driven — more driving means more kWh to put back.
- Your car's efficiency (miles per kWh) and charging losses.
- Crucially, when you charge: peak vs. off-peak pricing can change the cost dramatically.
How to cut it
- Schedule charging for off-peak/overnight hours — many utilities have much cheaper EV rates.
- Only charge to ~80% for daily driving unless you need the full range.
- Check for a utility EV plan or time-of-use tariff built for home charging.
- Even better, charge from rooftop solar in the middle of the day if you have it.
