EV Charging Cost: 150 Miles, 5 mi/kWh, $0.10/kWh
Calculate the charging cost for 150 miles in a highly efficient EV at a low overnight electricity rate of $0.10/kWh.
How to use this tool
- Enter the distance you want to charge for, in miles.
- Enter your EV's efficiency in miles per kWh (from its trip computer).
- Enter the electricity rate at the charger, in dollars per kWh.
- Set the charging efficiency (about 0.90 for home Level 2).
- Read the grid energy used and the charging cost.
With a highly efficient EV and cheap overnight charging, 150 miles can cost very little — find out exactly how much.
Frequently asked questions
- How much does it cost to charge an EV at home?
- For a typical EV at 4 mi/kWh, 90% charging efficiency, and $0.15/kWh, about 100 miles of range costs roughly $4. Overnight off-peak rates make it cheaper; public DC fast charging at $0.30–0.50/kWh costs several times more.
- Why is grid energy higher than battery energy?
- Charging isn't perfectly efficient. Some energy is lost as heat in the onboard charger, cables, and AC-to-DC conversion, so you draw more from the grid than ends up stored — usually 5–15% more.
- Does cold weather increase charging cost?
- Yes. Cold reduces driving efficiency (more kWh per mile) and adds battery-conditioning and cabin-heating loads, so the same trip needs more energy. Lower the mi/kWh input to reflect winter driving.
