When it comes to electric cars top speed isn’t the holy grail. It’s the speed at which you can top up the battery that’s much more important.
So, we consider this the ultimate version of speed dating – how quickly can you plug into one of our High Power 350kW-capable chargers and hit the road again with your battery replenished?
To make sense of the rankings we need to first explain some science. I know, this is the worst date ever. But bear with us, first impressions aren’t everything…
You’ll see many cars claim 150kW+ charging capability while some of the latest top-end models are now capable of achieving the full 350kW. However, this maximum is a peak and not a constant.
The top rate that’s advertised will only be achieved for a short period, usually at around 50% State of Charge (SoC). Think of it like sprinting, it takes a bit of time to get going out the blocks, then you’re like Usain Bolt, but you can only keep going for a short while before you need to ease off.
This is what’s known as the charging curve.
Each car has a different charging curve, and some models are able to sustain their peaks for longer, which means the average power across a whole charge is higher – and for you, that means a quicker charge.
See, we told you it was good pillow talk. The charging curve is the same reason that once you get above 80% the car will slow the maximum charging power to avoid the cell voltages exceeding their limit.
And that takes us onto our speed dating scoreboard. As we’ve explained above, just quoting the maximum power capability is not enough to really tell which car is fastest at charging. Instead, we’re using figures from ev-database.org, which has calculated a “miles per hour” charging figure.
This takes the average power of a car across a 10 to 80% charge and calculates how many miles it would add over the course of an hour. We’ve also quoted the time it’ll take in real-world terms to achieve that 10-80% top up – this is of course dependent on battery size as well as charging capability (a bigger battery, and therefore more range, means more cells to charge).
The face of the next generation of electric cars is the Hyundai IONIQ 6. A sleek design to optimise aerodynamics for added range combines with a comfortable and practical interior. Add in class-leading charging capability and this is a seriously impressive EV.
If you look up any ‘best-ofs’ list (whether they’re EV-only or not) then the Porsche Taycan will invariably be there. It takes everything that’s great about Porsche sportscars and makes it even better. Stylish, great to drive and with incredible performance. The charging speeds mean you’ll have even more time out on the open road enjoying the Taycan.
The Kia EV6 really is love at first headlight for us. It ticks every box and more. Not only is it practical and stylish, but it can also be one of the fastest accelerating or longest range EVs out there, depending on how you spec it. And naturally, charging capability is one of the best on the market.
The Audi e-tron GT is a serious machine. Power, precision, performance and the closest you’ll get to matching the Porsche Taycan. Now we know looks aren’t everything and love is blind, but we also can’t ignore that the e-tron GT is also one of the best-looking Audis of recent years.
Unless you’re a big golf fan and keep track of Tiger Woods’ driving habits, you might not be too familiar with the Genesis brand. They’re relatively new to the UK but have made a big splash. The Genesis GV60 is its first all-electric car and it’s dripping with technology, looks good and is prepped for the top power chargers. It’s a hole-in-one.
