How much does it cost to charge a Hyundai Kona Electric?

A full charge for a 2025 Hyundai Kona Electric Long Range, 17-inch wheels costs about $13.62 at home, at the US average residential electricity rate of 18¢/kWh. A 2019–2023 Hyundai Kona Electric costs $12.54 to $13.00 to fill at the same rate, depending on version.

That full charge draws roughly 76 kWh from the wall and buys 261 miles of EPA-rated range — about $0.052 a mile. Filling up the 2025 Hyundai Kona Electric costs $9.35 in Idaho, the cheapest state, and $25.17 in California.

What it costs to charge a 2019–2023 Hyundai Kona Electric

At the US average rate of 18¢/kWh, a full charge of a 2019–2023 Hyundai Kona Electric costs $12.54 to $13.00 depending on version, against $13.62 for the 2025 Hyundai Kona Electric above. Per 100 miles it runs $4.86 to $5.04, against $5.22.

Every first-generation Kona Electric was rated for 258 miles of range, and its consumption moved between 27 and 28 kWh per 100 miles from one model year to the next. Either way it uses slightly less energy per mile than the 2025 Long Range, and with three fewer miles of range a full charge takes less energy too. The EPA listed a single front-wheel-drive version each year, so every trim shares these figures.

What it costs at three real electricity rates

Your rate is the only input that really moves this number, so here is the same car at three real ones — the cheapest state, the national average, and the most expensive large mainland market.

Hawaii is higher still at 52¢ — a 4.2:1 spread from the cheapest state to the dearest. EPA figures checked September 2026; electricity rates checked August 2026.

What it costs per mile

A Hyundai Kona Electric costs about $0.052 a mile to charge at home at the US average electricity rate, or $5.22 per 100 miles. That is energy only — the EPA rates this car at 29 kWh per 100 miles measured at the wall socket, so charging losses are already inside the figure and should not be added again.

Per mile is the number that survives a change of car: it does not care about battery size, so it is the only fair way to line this car up against one with a much bigger or smaller pack.

What it adds to your electricity bill

Charging a Hyundai Kona Electric at home adds about $52 a month to your electricity bill at the US average rate, driving 12,000 miles a year. That is the yearly cost of $626 spread evenly across twelve months — a month with a road trip in it costs more, and a quiet one costs less.

Nothing else on the bill changes: the car draws the same kilowatt-hours whatever else is running in the house, so the increase is the charging and nothing more.

At the cheapest state rate the same driving adds $36 a month, and $96 at the most expensive — the table above has all three. If your utility offers an overnight or time-of-use rate, charging on it lands at the low end rather than the middle.

Where the numbers come from

The EPA rates this Long Range, 17-inch wheels at 29 kWh per 100 miles with 261 miles of combined range. Those two figures together give the energy for a full charge, which is where the 76 kWh above comes from.

We work it out that way rather than quoting a battery size on purpose. Manufacturers publish gross capacity, which includes a buffer at each end of the pack that never takes a charge, so a cost built on it overstates your bill. And the EPA measures at the wall socket rather than at the battery, so charging losses are already inside the figure — no need to add them, and adding them would count the same loss twice.

What this means for this car

The EPA has no 2026 Kona Electric listing, so this page prices the 2025 model year, the latest it rates. The 2024 Long Range carries the identical 29 kWh per 100 miles and 261 miles, so the figures here hold for it too. That makes the Kona cheaper per mile than the Ioniq 5 at 30, though not the Ioniq 6, and a full charge of about 76 kWh is one of the smallest on this site. For 2025 the EPA split the Long Range by wheel size: on 19-inch wheels it is rated 31 kWh per 100 miles with 230 miles of range, about 7% more energy per mile and 31 fewer miles between charges for a wheel choice. The Standard Range saves nothing per mile either. Its smaller battery and 99 kW motor are rated 29 kWh per 100 miles, the same as the Long Range, over 200 miles. The unusual part is that the first-generation 2019–2023 car was rated more efficient than its replacement, at 27 or 28 kWh per 100 miles depending on year with 258 miles of range, so a used Kona Electric uses slightly less energy per mile than a new one.

How it compares

All at 18¢/kWh and 12,000 miles a year. The gas comparison is illustrative — it is not a claim about any particular car.
