Kia's sleek crossover costs about $14.40 to charge at home.
Pre-filled with the Kia EV6 Long Range RWD (84 kWh, 2025): 80 kWh usable battery, 3.4 mi/kWh. Change any number to match your car.
The Kia EV6 Long Range shares its 800-volt platform with the Hyundai Ioniq 5, which means it shares the same party trick: a 10% to 80% fast charge in about 18 minutes. The 2025 refresh grew the long-range battery to 84 kWh (80 kWh usable), good for an EPA-estimated 310 miles in rear-wheel-drive form. A full home charge at the US average rate costs about $14.40, or roughly 5 cents per mile. For 2025 Kia also switched to a native NACS port, so the EV6 now uses Tesla Superchargers directly.
Where the Ioniq 5 leans retro and boxy, the EV6 is sleek and driver-focused, with sharper handling and a lower roofline. Under the skin the two cars are twins: same battery, same motors, same ultra-fast charging. The EV6 Long Range RWD is the efficiency pick of the range — 310 miles beats every all-wheel-drive version — and it carries Kia's 10-year/100,000-mile battery warranty, the best in the business. If you want the fastest-charging EV that still feels like a driver's car, this is the one.

Efficiency is the number that matters most for your wallet. At 3.4 miles per kWh, every kilowatt-hour of electricity takes you 3.4 miles. A more efficient car needs fewer kilowatt-hours for the same trip, so it costs less to charge even with the same battery size.
The table below uses the US average home rate of $0.18 per kWh (EIA, August 2026) and the national public fast-charging average of $0.48 per kWh (estimate). The "mixed" column assumes 80% home charging and 20% public charging, which matches how most owners actually charge.
| Annual mileage | Home only | Public only | Mixed (80/20) |
|---|---|---|---|
| 8,000 miles | $423.53 | $1,129.41 | $564.71 |
| 12,000 miles | $635.29 | $1,694.12 | $847.06 |
| 15,000 miles | $794.12 | $2,117.65 | $1,058.82 |
At home the EV6 is inexpensive to run. Its 11 kW onboard charger refills the battery overnight, adding roughly 30 miles of range per hour on a Level 2 wall connector. Driving 1,000 miles a month at the US average home rate of $0.18 per kWh costs about $53; in Texas ($0.159) that is around $47, and in Washington ($0.146) about $43. In California ($0.298 per kWh) the same month costs roughly $88. Because the battery is large, a full 0–100% charge at home takes about 7 to 8 hours on Level 2 — comfortably overnight — and most owners simply plug in every evening and never think about range again.
The EV6 is at its best on a powerful DC fast charger. Its 800-volt system accepts up to about 240 kW, completing a 10–80% charge in roughly 18 minutes on a 350 kW station and adding over 200 miles of range in the process. On a 150 kW charger the same session takes closer to 30 minutes, and on Tesla Superchargers the car charges more slowly because of the voltage mismatch — still useful, but not the headline speed. At the national average public rate of about $0.48 per kWh, a full charge costs around $38, and a typical 10–80% road-trip stop costs roughly $27. That is about two and a half times the home-charging price, which is why home charging remains the cheapest way to run an EV6.
Kia buyers often cross-shop the Mazda CX-5, a stylish gas SUV averaging about 28 mpg combined. Over 60,000 miles in five years the CX-5 burns about 2,143 gallons, costing roughly $8,786 at $4.10 a gallon. The EV6 uses about 17,600 kWh for the same distance, costing around $4,240 on a typical 80% home / 20% public mix. The five-year fuel saving is about $4,550 — and the EV6 needs no oil changes, no transmission servicing and far less brake work. The EV6 starts from about $42,600, and the fuel saving plus Kia's long warranty make the total cost of ownership very competitive against gas crossovers that cost less up front.
| 5 years / 60,000 miles | Kia EV6 | Mazda CX-5 (gas) |
|---|---|---|
| Energy used | 17,647 kWh | 2,143 gallons |
| Fuel cost (5 years) | $4,235.29 | $8,785.71 |
| You save with the Kia EV6 | $4,550.42 over 5 years | |
EV figure uses a typical 80% home / 20% public mix at the US average home rate ($0.18/kWh) and the $0.48/kWh public average. Gas figure uses 28 mpg combined and $4.10 per gallon (AAA, November 2026). Fuel costs only — purchase price, insurance and maintenance are not included.
Electricity prices vary enormously by state. The table below shows what a full 0–100% home charge of the Kia EV6 costs in the ten biggest EV states, at each state's average residential rate (EIA, August 2026).
| State | Rate ($/kWh) | Full home charge |
|---|---|---|
| California | $0.297 | $23.80 |
| Texas | $0.159 | $12.73 |
| Florida | $0.150 | $11.99 |
| Washington | $0.146 | $11.70 |
| New York | $0.286 | $22.92 |
| Arizona | $0.150 | $12.04 |
| Colorado | $0.172 | $13.74 |
| Oregon | $0.159 | $12.74 |
| New Jersey | $0.246 | $19.69 |
| Georgia | $0.159 | $12.72 |
| US average | $0.180 | $14.40 |
A full 0–100% home charge of the Kia EV6 Long Range RWD (84 kWh, 2025) costs about $14.40 at the US average residential rate of $0.18 per kWh (EIA, August 2026). At a public DC fast charger, the same charge costs about $38.40 at the national average of $0.48 per kWh.
About $0.053 per mile on home charging alone, or about $0.071 per mile on a typical mix of 80% home and 20% public charging. Driving 1,000 miles a month costs about $70.59 on that mix, or about $847.06 a year for 12,000 miles.
On a DC fast charger, the Kia EV6 goes from 10% to 80% in ~18 minutes at up to 240 kW. At home on a Level 2 charger, a full charge takes roughly 7 to 10 hours overnight, depending on your charger's power.
Yes — for almost every EV owner. Home electricity averages about $0.18 per kWh in the US, while public fast charging averages about $0.48 per kWh. A home Level 2 charger typically costs $500 to $1,500 installed (before any utility rebates), and most owners recover that cost in one to two years of fuel savings.
Among large EV states, Washington is cheapest at about $0.146 per kWh, followed by Florida at $0.150 and Texas at $0.159. California is the most expensive large state at about $0.298 per kWh. Your state can change your monthly charging bill by $40 or more.
They are very close. The EV6 Long Range costs about $14.40 for a full home charge versus about $13.50 for the Model Y, because the Model Y is slightly more efficient. But the EV6 charges much faster on a 350 kW DC charger — about 18 minutes from 10% to 80% versus about 25 minutes for the Model Y. For home charging the Model Y is marginally cheaper; for road trips the EV6 is faster.
Estimates only. Battery capacity is usable capacity (usable); Tesla does not publish usable capacity, so Tesla figures are widely reported estimates. Electricity rates are statewide averages from the U.S. Energy Information Administration (August 2026); your utility, rate plan, time of use, taxes and fees will change your actual bill. Public charging at $0.48/kWh is a national average estimate. EPA range and efficiency are estimates for the Long Range RWD (84 kWh, 2025) trim; real-world figures vary with speed, temperature, terrain and driving style.
