Polestar 5 prototype charges in 10 minutes

Those wild 10-80 per cent SOC claims you've heard? Now one's actually happened


Those of you with regular experience of electric cars and public charging will know that maximum charge rates for both need to be taken with a large grain of salt. Lots and lots of stars need to align, basically, for claims to be met and batteries to be replenished at the advertised speed. The dream is for a depleted battery to become very near full again in not much time at all, because we all have better places to be than at a services, but we’re not quite there just yet. 

Polestar reckons it’s made a big step forward, though, with the 5, as a prototype has recorded a 10-80 per cent charge in just 10 minutes. It pulled a mighty 310kW from a DC charger at the beginning, increasing to more than 370kW at 80 per cent state of charge. It benefits from StoreDot’s Extreme Fast Charging (XFC) tech, with the potential of adding 200 miles of range in 10 minutes (a standard 5 will use a 77kWh battery, with the option of 100kWh).

Polestar says this was a world first demonstration of the 10-minute 10-80 per cent charge in the real world, using ‘silicon-dominant cells in a driveable vehicle’. All previous tests have been lab experiments. The XFC battery tech ‘could be applied to future Polestar vehicles’; this seems to be a demonstration of what’s possible rather than a promise of what’s right around the corner, but it still feels like a step in the right direction. 

Thomas Ingenlath, Polestar CEO, said: “Time is one of life’s greatest luxuries, and as a manufacturer of luxury electric performance cars, we need to take the next step to address one of the biggest barriers to EV ownership – charging anxiety. With this new technology, on longer journeys when drivers do stop they’ll be able to spend less time charging and be back on the road faster than before. In fact, that stop time will be more akin to what they experience with a petrol car today.” The 5 launch is still believed to be on track for next year, following a reveal in 2023. Best get planning the European road trip now…

That's one in the eye for the argument that EVs take too long to charge. Let's see what they'll complain about next...

Assuming the charge point can supply that level of current?

And where does it store the energy so that it can do so - a massive capacitor? How how long does it take to charge *that*?

There's no way the grid will be able to supply that...

Being able to find one of these high-speed chargers, for a start, and probably the exorbitant price per KWH.

This is how progress happens, a lot of small, incremental steps, so the car can now accept that much charge in that time, so now the charging points need to catch up.

They managed to put that much in so its obviously possible, will be commonplace in a few years I expect.

There are already many stations that can provide 350kW, with 400kW becoming the state of the art. Will the grid need updating? Sure, but it's a multistep, multifaceted problem that will be solved by parallel development.

I don't see why it would be an issue - teslas superchargers can already pump out 250kw - and you often see a row of 20 of those. Having 12 400kw chargers with a similar power supply shouldn't be an issue

Love this sort of thing. Hopefully yes as long as they dont give it to some sort of "BT Openreach" outfit to roll it out!

It will be when it’s available and shown to work that way away from test conditions, in the same way that the autonomous driving that I paid Tesla for in 2019 will be great when that’s delivered.

Who is 'they'? Did you ever consider that some people want ICE cars and that there's nothing wrong with that? Not everything has to be tribalism based on purchasing decisions

What we'll need is a load of diesel generators powering the charging points!

You asked and they delivered! (See above!)

Sounds like a real advance though and if the facilities catch up, then perfect.

Still need to find better ways of mining but we aren't worried about African children around these parts. wink

Also there's the lack of decent noise. Need to be able to install mp3s. I'd have a clipclop sound or a chufchuf sound.

I was an early(ish) adopter, paying £96,000 for a Model S in 2019, and find it tiresome that when I mention the problems that I had with it that I get lumped in with these strange “they” people.

It had physical build problems. It had software problems, its range was massively less than Tesla promised, the autonomous driving had been reduced in scope by delivery from the test drive, and the rate of charging that I actually got at superchargers was rarely what was promised.

I’m now not going to naively accept the promises of jam tomorrow touted by EV manufacturers or be willing to beta test cars that have been rushed out without proper testing having been done by those manufacturers.

Interesting dichotomy - on the one hand the EV manufacturers need to keep putting out these 'hope value' stories to maintain interest in a tech that for most simply doesn't work.

One the other hand who would actually buy one right now with this promise of the 'holy grail' just a few years down the line?

I suspect pumping more KWh in quickly is a simpler proposition than cracking full autonomous driving to be fair.

There are still downsides and compromises with EVs but its heartening to see the barriers being broken down to lower the bar to entry, which is what I have been predicting based on how tech development tends to play out.

One of the crucial questions that needs to be answered.

The vehicle may well have software that doesn't allow repeated fast charging.

Hmm, folk in the office I work in, look out of window, see their EV's, three Teslas, an Audi eTron and an Ipace, they all managed to get here this morning.

Where is the "Doesnt work" bit ?

Or do you mean doesnt work for everyone, all the time which would be accurate ?

I think the route of 100kwh+ batteries may turn out to be a dead end if we want people to adopt EVs as the future.

Our town car does 45 miles on a charge, which is plenty for what it’s designed for. Big batteries are more desirable as charging is slow, so people want to avoid it on long journeys.

Get it down to genuinely 5 minutes to add 100 miles and people may accept 50kwh batteries, allowing lighter cars to suffice until battery technology can give us the bigger capacity in a lighter battery.

Nobody's ever going to charge it that fast every time. Vast majority of EVS are charged at home overnight, or in the workplace. Slowly. That's not going to change. These ultra rapid capabilities will be, for the vast majority of drivers, occasional use only.

It's a non-issue.
