Long waits at charging points have long been used as a reason to hold off buying an electric car, but that’s changing fast.
Advances in battery chemistry, cooling systems and inverter technology mean charging speeds have improved dramatically in recent years, with some electric vehicles now running on 800 volt electrical systems, double the voltage most EVs have traditionally used.
Higher voltage matters because it allows more power to flow into the battery without generating the extra heat you’d normally get from simply increasing current instead. That technology is also becoming steadily cheaper to produce, which is part of why it’s spreading across more models each year.
Range added per minute is the number that actually matters.
Not every EV behaves the same way at a charger, though. Some models hold onto their peak charging speed for longer stretches than others, while overall efficiency affects how much range you actually get back for each minute spent plugged in. That combination of factors makes a simple top charging speed figure fairly misleading on its own.
To properly compare EVs on a level footing, working out an average charging speed across a typical ten to eighty percent charging session, measured in miles of range added per minute, gives a much clearer picture of real-world performance.
What sets the fastest chargers apart from the rest?
A lot of the cars near the top of this list share a common thread: 800V electrical architecture paired with battery chemistry designed to sustain peak charging power for longer, rather than throttling back early to protect the cells. Some manufacturers achieve this through cylindrical battery cells borrowed from motorsport, which are easier to keep cool than the flatter pouch cells used in most EVs.
Price doesn’t always line up with charging speed either. Some of the quickest charging cars on this list are also among the more affordable options, while a few truly premium models fall further down the ranking, proving that fast charging comes down to engineering choices rather than simply how much a car costs.
One car in particular is rewriting the rulebook entirely.
Sitting well ahead of everything else on this list is a car capable of adding well over four times the range per minute of its nearest rival, thanks to an entirely new ultrafast charging technology just arriving in the UK. We’re talking, of course, about the Denza Z9 GT. It’s the kind of leap that makes the rest of the list look almost pedestrian by comparison.
The charging network needed to actually deliver those speeds doesn’t fully exist in the UK yet, but if the planned rollout happens on schedule, it could actually reshape what a typical motorway charging stop looks like for its owners within the next year or so.
The 10 fastest-charging electric cars on sale in the UK
10. Audi A6 E-tron Performance Sport – 15.6 miles per minute added. WLTP range 469 miles, charges 10-80% in 21 minutes (328 miles added), £68,860. Needs the 100kWh battery for 270kW charging; the 83kWh pack tops out at 215kW.
9. MG IM6 100 Long Range – 16.0 miles per minute added. WLTP range 388 miles, charges 10-80% in 17 minutes (272 miles added), £48,495. Single motor version, 75 miles further than the four-wheel-drive options.
8. Porsche Taycan – 16.4 miles per minute added. WLTP range 421 miles, charges 10-80% in 18 minutes (295 miles added), £91,196. Entry-level single motor version is both the quickest charging and longest range Taycan.
7. BMW iX3 50 xDrive – 16.4 miles per minute added. WLTP range 493 miles, charges 10-80% in 21 minutes (345 miles added), £60,655. Larger battery option adds four-wheel drive and 400kW charging.
6. MG IM5 100 Long Range – 18.2 miles per minute added. WLTP range 441 miles, charges 10-80% in 17 minutes (309 miles added), £45,495. Entry-level 75 Standard Range skips 800V tech, roughly halving charging speed.
5. Volvo EX60 P12 AWD Plus – 18.5 miles per minute added. WLTP range 503 miles, charges 10-80% in 19 minutes (352 miles added), £64,860. Enough range for Brighton to Edinburgh with charge to spare.
4. BMW i3 50 xDrive First Edition – 18.8 miles per minute added. WLTP range 563 miles, the longest on this list, charges 10-80% in 21 minutes (394 miles added), £57,905.
3. Xpeng G6 Long Range – 19.0 miles per minute added. WLTP range 326 miles, charges 10-80% in just 12 minutes (228 miles added), £44,990. The cheapest car on this list, using durable LFP battery chemistry.
2. Mercedes-AMG GT 53 4-Door Coupé Premium – 21.1 miles per minute added. WLTP range 483 miles, charges 10-80% in 16 minutes (338 miles added), £103,275. The 536bhp entry-level version charges fastest.
1. Denza Z9 GT – 64.9 miles per minute added. WLTP range 373 miles, charges 10-70% in just 5 minutes (224 miles added), £105,000. Peaks at 1500kW using BYD’s new Flash charging technology, nearly four times faster than the quickest rapid chargers currently in use.
Charging speed alone obviously isn’t the only thing worth weighing up when choosing an EV, but with technology advancing this quickly, the gap between electric and petrol refuelling times is shrinking far faster than most people probably realise.
