Quick Facts About Fast-Charging Electric Cars
- How fast an electric car battery charges depends on many variables: the type of charger being used, the battery capacity, environmental factors, and more.
- Level 1 chargers are the slowest and add a few miles per hour; Level 3 DC chargers are the fastest and can replenish several miles of range per minute.
- Manufacturer claims about how fast EV batteries charge are based on near-perfect conditions.
- Technology evolves rapidly and improvements to electric car charging speed roll out frequently.
Get to know the fastest-charging electric cars. Electric vehicles (EVs) are fast becoming mainstream, but it’s still the Wild West when comparing them to one another.
We set out to find the five fastest-charging electric cars and quickly found that we’d waded into a chaotic question without a simple answer.

5 of the Fastest-Charging Electric Cars
So, how should we compare electric car charging times? Given the wide disparity of data available, we have to pick one flawed measurement over another and accept that we’re using unverified manufacturer data to find the fastest range per minute specs. With that in mind, we’ve calculated how fast each electric car’s battery can charge under peak conditions.
1. Hyundai Ioniq 6 — 16.1 miles per minute
The all-new Hyundai Ioniq 6 was delivered to U.S. customers in spring 2023. The all-electric sedan is based on the same platform as the multi-award-winning Ioniq 5. Hyundai has performed some clever electrical engineering with the Ioniq 6, allowing it to charge at a maximum of 800 volts — that’s about as good as it gets. That same fast charger can move the battery’s needle from 10% to 80% state-of-charge in only 18 minutes.
2. Lucid Air — 16 miles per minute
You may not have seen many Lucid Air vehicles on the road yet, but you probably will soon. The California startup delivered its first EVs to customers in 2022.
With a starting price of $77,400 (plus a $1,500 destination charge), the Air has the longest EPA-certified range of any electric car. It has a max EPA range of up to 516 miles with 19-inch wheels. The manufacturer boasts owners can use DC quick charging to get 200 miles of range in as little as 12 minutes.
3. Porsche Taycan — 15.5 miles per minute
Porsche’s Taycan is capable of a quick surge of charging that will, the manufacturer says, give you 60 miles of range in 4.5 minutes. It won’t charge at that rate indefinitely, but should you find your battery running low, getting another hour’s worth of highway-speed driving in the time it takes to order a cup of coffee is nice.
4. Tesla Model 3 — 15 miles per minute
America’s second-best-selling electric car, the Tesla Model 3, (Model Y in 2023 was No. 1), is also capable of a rapid charge to 80% of its battery capacity. The Model 3 holds a Guinness World Record for the fastest charge — three drivers crossed the United Kingdom in a Model 3, stopping just three times to recharge for about half an hour each time.
5. Kia EV6 — 14.5 miles per minute
Kia’s first dedicated EV is a sleek-looking hatchback with an EPA-certified range of up to 310 miles. It’s offered in several models, from a good-enough 167 horsepower to a wait-I-thought-this-was-a-Kia 576 horses. Thanks to its 800-volt architecture, it charges faster than most rivals.
Methodology: The above calculations use “miles per minute” to measure the maximum mileage each vehicle can accept in 1 minute from a Level 3 DC fast charger at 350 kW. These cars will not charge at a constant rate, and each has a battery of a different size, so miles per minute will not tell you how long each vehicle takes to reach full charge. But miles per minute makes a helpful shorthand to help show what you’d be getting into if you were to buy any of these cars.
The State of Electric Car Charging
Just a few years ago, manufacturers offered fewer than 10 electric vehicle models for sale in the United States. Infrastructure held them back — there were few places to charge and buyers legitimately worried about running out of juice far from the nearest location to recharge.
The infrastructure is still far from perfect, but some challenges are fading for the more than 40 models on the market today. You can now easily find fast chargers outside shopping centers and offices in many metropolitan areas, and networks of chargers will begin spreading along interstates as electric companies realize there’s money in it for them.
If you should find yourself in need of a charge, you’ll soon be able to order a remote charger delivered to your location with a few clicks on your phone. There will even be robots charging cars in parking garages.
With the infrastructure growing, automakers are racing to produce more electric cars. In the next couple of years, as many as 100 new models could be available for sale. They’ll include at least one from almost every manufacturer, from Kia to Rolls-Royce.
There may also be 100 ways to calculate how long electric cars take to charge.
How You Charge EVs Is Everything
All gas pumps are roughly similar. But the same can’t be said for chargers.
Nearly every electric car sold in the U.S. today comes with a Level 1 charger — not much more than an extension cord you can plug into a standard 110-volt outlet for a trickle charge. It’s not unusual for an electric car to take all night to get to a full charge that way.
Functionally, that’s fine for most drivers on an average day. You probably rarely drive longer distances in a day than the average electric car range. Most of us settle down for the night somewhere where we could plug it in. Think of this as filling a swimming pool with a water gun.
Many buyers, though, will want to step up to a Level 2 charger. Usually installed by an electrician (though we know of one you can install yourself), these use a 240-volt outlet like an electric dryer. They usually cut that charging time by more than half. A Level 2 charger is a garden hose for our swimming pool analogy.
Finally, there are Level 3 chargers out and about, like Tesla’s Supercharger stations or the universal charging stations Electrify America built into some gas stations and shopping malls. These use DC current — up to 350 kWh if your car can take it — and will charge an electric car far faster than anything you can do at home. It’s like calling the fire department to fill your pool directly from an open hydrant.
However, not every electric car can accept power at that rate. Electric cars manage how much power they will draw from a charger. They throttle back what they receive from the most powerful Level 3 chargers to prevent damage to their components.
Electric cars also don’t charge at a constant rate. Testers often find that the first few percent of charge enters the EV battery quickly, and the last few percent can take much longer.
EV Battery Size Is an Issue
Even if two electric cars can accept the same power flow, that doesn’t mean they’ll finish charging simultaneously. Electric vehicles offer different size batteries. Sometimes different trim levels of identical electric cars carry different size batteries. The Tesla Model S on the road today, for instance, has been sold with battery packs measuring 60, 70, 75, 85, 90, and 100 kWh.
In other words, sometimes you’re filling a kiddie pool, and sometimes an Olympic-size lap pool.
Manufacturer’s Claims: No One Fact-Checks Them
A government agency verifies fuel economy for gasoline-powered cars. Another will check that fuel pumps are dispensing an actual gallon for every gallon for which they charge. But charging times? Manufacturers can claim whatever they’d like. No one is verifying what they say.
And they all say something different.
Some manufacturers report the amount of time an electric car takes to charge from an empty battery to 100%. Others say time to 80%. At the same time, others report time from 10% to 80% or 10% to 90%. And virtually all report their numbers in a best-case scenario, using a Level 3 charger that buyers may not use or be able to access.
No one checks these claims.
Battery Technology Is Changing Rapidly
Finally, charging speed calculations are tricky because they don’t last. Battery technology is one of the hottest research fields on the planet today. The company that creates better batteries will improve electric vehicles and enable power grids to store solar electricity for use overnight, build phones that can run on reserve power for days, and even make human missions to Mars easier.
Consequently, new and improved batteries roll out regularly. Automakers know this and sometimes change their configuration on the fly (Tesla, for instance, builds more efficient batteries into its cars as they become available, never waiting for the next model year to improve what they’re offering).
Thus, any calculation involving the cars currently on the market can and will change at any moment. Perhaps even dramatic change with solid-state battery development will happen soon.
