80 to 90 took almost as long as 10 to 80. Must be a VERY good reason to sit there for that. I would prefer the old one and go to 80% faster :) 32min old vs 41min new.
I've found most people, and a lot of motoring journalists sadly, don't understand charging curves. That headline figure will sell cars as an improvement even if the overall charge is now slower as a result. Sad this is the case and not good for the long-term. Hopefully they 'fix' it again Great to see you back, Bjorn. Hope it wasn't too exhausting
It is interesting that the pack voltage ⚡ on the newer one is higher. This indicates that the percentage is not exactly the same. Did you compare the charged energy?! Unfortunately it was not displayed for the old one.
I was just popping into the comments for the same thing. At the low charge the old had a higher voltage indicating a larger unusable bottom buffer and by high state of charge the old had lower voltage also indicating a larger unusable top buffer. Curious if it actually increased capacity/range a little with the software update.
Since most lithium ion batteries use Constant Current charging up to about 80%, try just watching the Amps on the displays. The new charging algorithm peaks with higher amps at low SoC but then limits earlier than the old algorithm. However, at higher SoC the new algorithm allows higher amps than the old one. You can also see there are "stair steps" in the amps allowed depending on SoC. Bjorn, it would be nice to plot just Amps versus SoC of the batteries below 80% to see the "stair steps" and where they kick in. And I'm happy to see that you are feeling much much better!
Good to to have you back Bjørn! Full of energy again and talking fast - so fast that I had to slow the video down. But then you sounded drunk so I had to turn up the speed again :-)
Great to see you back to business Bjorn! It was like a horse racing! :) BTW, could be a difference be a result of different batteries temperature? There can be a lot of factors influence the result.
With this types of updates, by looking at the voltages you can tell how the BMS priorities have been changed. Because the new one has higher voltages it means that the new BMS goes deeper into the top buffer. Looks like the voltages at cell level would be around 4.2V at 100% which honestly I am not a fan of. I would never charge > 95% if I had a Polestar as NMC cells don't like higher voltages. 10-90% in 58 minutes is disappointing in 2021. Chinese LFP cells do it in 35-40 minutes. 18-23 minutes more for a charge stop is a big difference ... 30 minutes total stop is a sweet spot, I hope more manufacturers will optimize for this.
@@bjornnyland At 90% both versions charge with pretty much the same intensity (33A and 34A), yet the new pack has +4V (449V vs 445V). That means that the resting voltage (at 0A) would be probably around 4.22V (new) vs 4.18V (old) at full charge (I believe the pack is 104p, 3s). 4.18V is kind of ok, 4.22V is crazy high. There is a threshold at about 4.2V that increases exponentially the parasitic reactions inside the cells, which is why it is recommended not to charge to 100% all the time on pretty much all packs. I like packs with top buffer that protect the battery in all cases. Seeing an update that eats into the top buffer *without* increasing the charging speed is disappointing - this is the only reason I wrote this comment. I hope Polestar owners won't charge to 100% daily.
Great to have you up and running again! To the test, as has been pointed out, a few details are missing: - the buffer has been decreased, does this not mean that the amount charged to 90% differs? - what was the battery temperature in both tests? (You did "battery warming jojo-ing" in your P2 vids)
It seems that they also adjusted the SoC limits at the battery. At 11% the old one has 410V and the new 402V....the middle section of the curve is nearly identical from 35-70% SOC. At 80% it is 438V to 444V and 90% = 445V / 449V. I wonder if they gained some more usable capacitythat way. Would be nice if the old ionity display would show the "kWh delivered" numbers.
@@bjornnyland I know...if you take a look at 85% SOC, the old version has 443V and 71A and the new version has 447V an 64A. This means that the new version is at a higher cell - SoC than the old version. Maybe they reduced the top buffer a little bit. It would be interesting if the old version has the same or lower usable capacity than the new one. A bit like Tesla but inverse...not programming more buffer on top, but programming less buffer.
Bjorn I think that they let out some of the buffer in the software update too? So charging 10-80% is a little larger on the new software so maybe may makes it 2-3kW more
I think this shows that Polestar, like Jaguar with their i-PACE, should concentrate more on developing their mk2 versions with hopefully another 50 miles range! I prefer both these models over Teslas, but that’s what both of these cars need to compete... not necessarily faster charging, but an extra 50 mile range in the first place!
The old one might charge to 100% quicker but can you use this charge? My old laptop charges much quicker than my new one but you cannot use the full charge so end up having to charge more often.
Could this be the next big thing from Bjorn? EV charging race commentary! Maybe he could drive each of the cars down to 5% charge and race them to 80% and 90% charge from different EV charge stations..or I'm sure he has a backlog of videos where he can review the timings and see which one charge first to 80% if he is still a bit too tired post covid?
That voltage is charging voltage (not battery voltage) and is depenent on charging power. At the same SoC, higher charging power means higher charging voltage.
Polestar is probably the worst car company ever created. If you want a western E-car get a tesla, if you want east, go with Nio or Xpeng. What the hell is Polestar doing? They will be bankrupt sooner than we know it.
@@steffo76 No, based on the multiple recalls, poor reviews from credible sources (car wow even shat on this company, and they are super easy going). I know this is supposed to be the pride of Swedish electric vehicles and all, but the polestar 2 is a complete failure. The polestar 1 even more so.
@@MainstreetMyrnnit's easy to forget Tesla have had many recalls also . I have had both model S and 3 and now drive a polestar2 and I'm still happy after >15000km. the new update made my charge way faster... so this test from Bjorn is very strange. What do you drive?

@@evilpcprogrammer they did. there was a buffer that they cut into.
and at the bottom 11%, the new one has lower voltage so it also reduces some bottom buffer
We are living in exciting times my friend. Keep doing a super job informing us on this tech.
Nice to see you back! 👍

Nope. This is not battery voltage.
there it is: the Viking back in office again!
*The king is back!*

Almost a photo finish at the end at about 1,5% difference.
The new one seems to jump all over the place at times.
Looks like the new one is designed for charging 5% to 55%, and hammer it to the next DC fast charger. Charger hopping!
Back to new normal,bto..But please keep the guard high against the covid-19.
bjorn tesla yes
Any plans to add Polestar 2 to the "Charging speeds compared" range table?
The old one might charge to 100% quicker but can you use this charge? My old laptop charges much quicker than my new one but you cannot use the full charge so end up having to charge more often.
No horses were whipped in the making of this video. Nice
was the battery warm enough on the new one? anyway, its really not much of a difference
Wow, I had expected more of the charge curve update...
Could it be lower temp in the pack in the new run?
Does the XC40 have the same firmware?
Crazy that slower charging software would be released.
Is this Long Range version? Have you charging test of Standard Range (Step in model)?
Could this be the next big thing from Bjorn? EV charging race commentary! Maybe he could drive each of the cars down to 5% charge and race them to 80% and 90% charge from different EV charge stations..or I'm sure he has a backlog of videos where he can review the timings and see which one charge first to 80% if he is still a bit too tired post covid?
If the 2 packs aren't have any changes, I guess it is slightly different of the BMS.
Do you have a charge curve/time on a 50kw charger? i remember you took the car with you to the north before.
Well thats disappointing ... thanks for sharing.
But does it charge the same amount. You showed that usable battery size is increased. Or am I missing something?
👍
pole star 2 looks like a sweet car
Nah. Don't go chinese. Don't support a regime that commits suchs atrocities against mankind.
@@erikvinnes it's expensive i wouldn't be able to afford it i drive a nissan leaf 40 kwh
I had one. I do absolutely not recommend. By far the worst car I ever had when it comes to quality. Stay away.
@@erikvinnes there are other good reasons to stay away as well. Quality is a main one.
Just tell me how long it takes to get full charged.
Too fast for us old ones
Liking this horse race style 😆
The new one voltage is up to 5-6V lower in several moments, less juice in the charger? (most probably not explain it all)
That voltage is charging voltage (not battery voltage) and is depenent on charging power. At the same SoC, higher charging power means higher charging voltage.
I thought I had video speed at 1.25, but no it was just Bjørn back to 1.00 :D
Much faster 🦖Bjo
Yo whats up
So in the real life test to 80 percent where charging throttles back the Old software win hands down. typical Swede
I would not charge over 80%
Mg is cheap but same tech
what a lousy update, when the result was a slower charge.
