About this appliance
A Level 2 charger draws 3.3 to 11.5 kilowatts. Because charging usually happens overnight, time-of-use rates matter enormously - off-peak charging can halve the effective cost in states with time-varying tariffs.
- At typical use this is a major load - around 7,884 kWh a year. Efficiency upgrades here pay back faster than on any small appliance.
- Models vary widely, from about 3300W to 11500W. Check the nameplate on your own unit rather than assuming an average, because the spread is more than 2x.
- If your utility offers time-of-use pricing, shifting this load off-peak can cut its cost substantially without using any less energy.

Common questions
How many watts does a ev charger (level 2) use?
A typical ev charger (level 2) draws about 7200 watts while running, with most models falling between 3300W and 11500W. Check the nameplate label or manual for your specific unit - the range is wide enough that averages can mislead.
How much electricity does a ev charger (level 2) use per day?
At around 3 hours of use a day and a 100% duty cycle, that works out to roughly 21.6 kWh per day, or about 648 kWh a month. Your actual figure depends on your usage and model.
Why does the cost differ so much between states?
Residential electricity rates across the US range from about 12.35 cents per kWh in North Dakota to 46.62 cents in Hawaii - nearly a fourfold difference. The same ev charger (level 2), used identically, therefore costs almost four times as much to run in the most expensive state as in the cheapest.
Is it cheaper to run a ev charger (level 2) at night?
Only if you are on a time-of-use or variable tariff. On a flat rate, the time of day makes no difference to cost. If you are on time-of-use pricing, off-peak hours are typically materially cheaper, and shifting this load can reduce its cost without reducing usage.
