The EV9 charges from 10 to 80 per cent in about 22 minutes and fills at home in roughly 9.7 hours. It is also the most expensive car on this site to run, at about $7.36 per 100 miles — some $994 a year over average US mileage. That is what a three-row electric SUV costs, and it is worth seeing plainly before you buy one.
How long it takes to charge
| Where | Power | Time | What that is |
|---|---|---|---|
| Home, Level 1 | 1.4 kW | ≈ 74 hours est | Empty to full on a 120 V household outlet at 12 A — suited to daily top-ups; a full charge can take days |
| Home, Level 2 | 7.7 kW | 13.9 hours | Empty to full, overnight |
| Home, Level 2 | 11.0 kW | 9.7 hours | Empty to full, overnight capped by the 11.0 kW onboard charger |
| Public DC, at its peak | 209 kW | 22 min | 10 to 80 per cent — the figure to compare cars on |
| Public DC station | 50 kW | ≈ 81 min est | 10 to 80 per cent, held back by the station |
| Public DC station | 150 kW | ≈ 27 min est | 10 to 80 per cent, held back by the station |
| Public DC station | 350 kW | ≈ 22 min | 10 to 80 per cent — the car reaches its own limit here, not the station |
What it costs to charge
| Charging at | Rate | Full charge | Per 100 miles |
|---|---|---|---|
| Home | $0.184/kWh | $19.63 | $7.36 |
| Public DC fast charging | $0.48/kWh | $46.08 | $19.20 |
| A petrol car, for comparison | $4.07/gal | — | $15.07 |
Assumptions, all editable in the running-cost calculator: $0.184/kWh at home (EIA US residential average) and $0.48/kWh on public DC, against petrol at $4.07 a gallon and 27 mpg. A pack this size is where charging losses stop being rounding: filling 96.0 kWh of battery pulls about 106.7 kWh through the meter, and the 10.7 kWh difference is heat in the charger and the cable. Every per-100 figure below already comes from a wall-measured rating, so it is not counted twice.
Over 13,500 miles a year — the US average — that is $993.60 of electricity charging at home, against $2,035.00 of petrol in the comparison car: a difference of $1,041.40 a year.
Big, and honest about it
At 40 kWh per 100 miles the EV9 uses about 54 per cent more energy per mile than the Ioniq 6. Over a year at average US mileage that is roughly $348 more in electricity.
None of that is a criticism. It is a 2.6-tonne car with three rows of seats and a 96 kWh pack, and physics charges for frontal area and mass. But it does mean the EV9 is the one car here where the running cost is worth putting into a spreadsheet before signing, because the gap against a smaller electric car compounds over the years you keep it.
Against petrol it still wins comfortably: about $994 a year against roughly $2,035 for a 27 mpg car — and a petrol vehicle of this size and weight would do considerably worse than 27 mpg.
The big pack changes what a percentage means
The EV9’s 22 minutes is quicker than a Tesla Model Y’s 27, and it is moving considerably more energy in that time — 10 to 80 per cent of 96 kWh rather than of 75. Measured in miles recovered per minute the gap is wider than the clock suggests.
The same size works against it at home: 9.7 hours on an 11 kW wallbox, and closer to fourteen on a 7.7 kW supply. If you are fitting a charger for an EV9, fit the bigger one.
Miles of range per hour, at every charger
The tables above answer “how long does a full charge take”. The question most drivers actually have at a plug is different: how much range goes in per hour, and how long until the next 100 miles are on the clock. This table answers that for every kind of charger, from a household 120-volt outlet to a 350 kW station, using the same figures as the rest of the page — the EPA’s 40.0 kWh per 100 miles, which is measured at the wall, and the measured 22-minute 10-80 per cent time. Rated range is used throughout; in winter, or at motorway speed, every row shrinks by the same proportion.
| Charger | Power at the car | Miles per hour | Add 100 mi | Empty to full | What sets the rate |
|---|---|---|---|---|---|
| Household outlet, Level 1 (120 V, 12 A) | 1.4 kW | 4 mi/h | 27 h 47 min | 74 h 4 min | the EPA figure, measured at the wall |
| Home wallbox, Level 2 | 7.7 kW | 19 mi/h | 5 h 12 min | 13 h 51 min | the EPA figure, measured at the wall |
| Home wallbox, Level 2 | 11.0 kW | 28 mi/h | 3 h 38 min | 9 h 42 min | capped by the 11.0 kW onboard charger |
| Public DC station | 50 kW | 147 mi/h | 41 min | — | held back by the station (estimate) |
| Public DC station | 150 kW | 442 mi/h | 14 min | — | held back by the station (estimate) |
| Public DC station | 350 kW | 540 mi/h | 11 min | — | the car’s own 22-minute 10-80 curve is the limit |
A Level 1 outlet adds about 4 miles an hour — 36 miles in a ten-hour overnight stop, enough for a commute and not for much else. A 7.7 kW wallbox raises that to 19 miles an hour, so 100 miles takes 5 h 12 min and the car is full from empty in 13 h 51 min. On DC the useful figure is 442 miles an hour at a 150 kW post, rising to 540 at 350 kW — 100 miles in 14 min. The 50 kW row is the one to remember on a road trip: the station, not the car, sets the pace, and 100 miles takes 41 min.
The per-hour figures do not change with your electricity price, but the cost of every hour does: the residential rate runs from 13.11 cents a kWh in Nevada to 52.72 in Hawaii (EIA, June 2026). We publish the arithmetic for this car in every state — Oregon, Pennsylvania, Rhode Island, South Carolina — and a 50-state table ranked cheapest first.
Where these numbers will mislead you
Loaded, it gets worse. The EPA figure is a test with a driver. Seven people and luggage is what this car is for and it is not what was measured.
Towing more so. Nothing on this site models a trailer, and a large SUV towing loses range far faster than a combustion equivalent.
Frequently asked questions
How long does it take to charge a Kia EV9?
About 22 minutes from 10 to 80 per cent on a fast enough DC station, and roughly 9.7 hours from empty on an 11 kW home wallbox — closer to fourteen on a 7.7 kW supply.
How much does it cost to charge a Kia EV9?
About $19.63 for a full charge at the US average rate, or roughly $7.36 per 100 miles — around $994 a year over average US mileage. That is the highest of the cars covered here.
Is the EV9 expensive to run?
Compared with other electric cars, yes — about 73 per cent more per mile than the most efficient car here. Compared with a petrol SUV of the same size, no: it still costs roughly half as much per mile.
How many kWh does it take to fully charge a Kia EV9?
The pack holds 96 kWh usable, but you pay for what comes out of the wall, and AC charging is roughly 90 per cent efficient — so a full charge draws about 107 kWh. That is the figure your electricity bill sees, and it is why the full-charge cost above is higher than capacity multiplied by tariff would suggest.
The same arithmetic across every car on this site: how many kWh a full charge really takes, 7.7 kW against 11.5 kW at home, and what charging costs per month.
