A 48A charger does not raise your monthly bill for the same driving — it shortens each session instead. At full output the EV-ACT5006T draws up to about 11.5 kW, so one full-rate hour moves roughly 11.5 kWh into the car, about $2.11 at the EIA’s US average residential price of 18.31 cents per kWh. Your monthly total is set by how many miles you drive and what you pay per kWh, not by the charger’s size.
Key Takeaways
- At full rate the EV-ACT5006T moves about 11.5 kWh per hour — about $2.11 at the average US price.
- Charger size changes session length, not the monthly energy total for the same miles.
- Your price per kWh and your mileage are what set the bill.
- Worked examples here use the EIA average of 18.31 ¢/kWh; substitute your own rate.
The Charger’s Side of the Maths
Energy is power multiplied by time. The figures below are worked examples at the 18.31 ¢/kWh average — your own bill will use your own price, and your car will not always take the full rate, since it slows down as the battery fills.
| Example session | Energy from the wall | Cost at 18.31 ¢/kWh |
|---|---|---|
| One hour at full 48A output (about 11.5 kW) | About 11.5 kWh | About $2.11 |
| One hour on the plug-in version at 40A (about 9.6 kW) | About 9.6 kWh | About $1.76 |
| An overnight top-up of 30 kWh | 30 kWh | About $5.49 |
Charging losses add a little on top: our published cost guide works with about 10% for losses when it prices a full battery. The point of the table is the shape of the number — an evening’s charging costs single dollars, not tens.
Why the Month Follows Your Miles
A smaller charger delivering the same energy simply runs longer. Our guide to what home charging costs works the general example: a car using about 0.30 kWh per mile at the wall, driven 1,000 miles a month, adds roughly 300 kWh — about $55 at the average price. That total is identical whether the energy arrived at 48A in short sessions or at 40A in longer ones. The 48A rate buys back your evening, not extra electricity.
Drivers who want the per-charge figures for their own car can start from how many kWh a charge takes and multiply by the price on their own bill, including delivery charges.
What Actually Moves the Number
- Your price per kWh. The single biggest variable. Rates differ widely between utilities, and a time-of-use or EV rate can price overnight energy lower — see how scheduling against time-of-use tariffs works.
- Your miles. Double the driving and you roughly double the charging energy, at any charger size.
- Losses and standby. A connected charger also draws a small standby amount when idle; the exact figure for any model is on its spec sheet. As a benchmark, ENERGY STAR notes that certified chargers use 40% less energy in standby.
Frequently Asked Questions
Does a 48A charger cost more per month than a 40A charger?
Not for the same driving. Both deliver the energy your miles need; the 48A unit delivers it in shorter sessions. The monthly kilowatt-hour total — the thing you are billed for — is the same.
How much does one hour of charging with the EV-ACT5006T cost?
At full 48A output, about 11.5 kWh in an hour, which is about $2.11 at the US average residential price of 18.31 ¢/kWh. Your car’s actual draw varies through the session, and your own price per kWh decides your figure.
Does the charger use electricity when the car is not plugged in?
Any connected charger draws a small standby amount to stay ready. Check the model’s spec sheet for its standby figure, and compare with the ENERGY STAR benchmark of 40% less standby energy for certified chargers.
