Charged to 90% last night. Charging ended about 23:50. Got in the car today, 84% battery 🤷🏻‍♂️

Edit! Now I’ve got back in and it’s 90%. Bless, little bit slow today! 😂

But this is happening over multiple countries and multiple different charging units.

So seems more the car than a charger issue.

Just because this worked for you may have a coincidence and your car was fine but charger was not.

Maybe, but why would you have a problem with me sharing a solution that seemed to immediately fix (for me) the same problem that everyone else has had? Since you don’t definitively know what the problem is, all user data contributes in one way or another to us finding a solution.

I only had the one day where it was acting weird. Hasn't done it since. Car happily sat at 39/40A for 8 hours the other day, from 7% to 90%. I'm putting in a 48A charger right now.

Glad to hear that, because there seems to be a lot of people with issues here. Sure, some of them might be on EVSE end, but I would suspect the car myself, if such variety of chargers and countries is involved.

 

[julianm]

Can verify I still have this issue with P1.8.

Started out at 40A, but within 15 minutes was down to 23A.

So when I read @julianm post above I had just arrived home for the day. 17% SOC. I had plugged in about 10 minutes earlier to my OpenEVSE 40 amp L2 charger in my garage. I went out to check it and sure enough it was charging at 26 amps. I am quite sure it was charging at my normal rate of 37.8 or 38 amps (delivered, set at 40 amps on car and EVSE) yesterday and for many days before that, as I have been faffing around with the app and PAK in the evenings every night this week.

But, I fixed it. Here’s what worked for me:

1. Stop charging on the charge port.
2. Unplug.
3. Infotainment reset in car.
4. Shut EVSE off at beaker box.
5. Unplug EVSE from wall (probably not necessary, but when charger rebooted it had a fault due to loss of power).
6. Plug car in again.
7. Car now charging at normal 38 amps, even after 30 minutes.

YMMV

Good that it worked for you (on that occasion). I'm not sure we should need a 7 step fix for something that happily worked 100% of the time before 1.6 update. Surely they should be able to narrow down on the cause since on one version (pre 1.6) is was working and then (1.6 onwards) it wasn't.

 

[julianm]

But, I fixed it. Here’s what worked for me:

I’m glad yours is fixed. I’ve done all these and more with previous versions without it being fixed. I’m guessing since I just got service center installed P1.8 that my car has had more than this level of reset. I’ll give it a shot eventually, but I’m not keen to waste more of my time on bugs Polestar won’t even answer me about.

Can verify I still have this issue with P1.8.

Started out at 40A, but within 15 minutes was down to 23A.

I received the update today at the service center and when I returned home I charged it. The results were almost identical to yours.

Just double checking here.... You are making sure after the update the Amps have been set back to maximum right?

Only reason I ask is that mine was set to 6A after the 1.7 update.

I’ve noticed that when I was on 1.7 it would start at 6A and then change to 32A by itself after a few seconds. Haven’t checked since I’ve been put on 1.8

Thanks for checking, but yes, the UI is showing 48A. I do get 40A charging just fine for... 15-30 minutes.

Happens again last night.

Also I know the car is near 90%... I guess 89%.... But reporting 81%.

I had this Yesterday morning where I knew the car was at 90% but it showed 82%.

I then did 30+ miles at 5degC and arrived with 74%... Exactly what Google predicted. Hell.... 8% SOC for 30miles.... Must be a record breaker! 🤣

I wonder if the low charge rate and the missing 8% SOC bug are related 🤔

 

[whiteco3]

Not great that you can't make full use of any cheap overnight charging tariffs. Also not being able to get full rates out of public 7kw or 11kw 'slow' chargers, makes them even slower. The only vague positive is that it doesn't happen all of the time, only a small amount of times, but I can't explain the randomness of it

Generally I charge my car over 2-3 nights for weekend use ... so not an issue it charges slower than I'd like, as either way I'm getting the 5p/kw.

However when I go out and about a few times a year I do rely on some of the 7/11kw chargers ... so hopefully 1.8 fixes that before then (although I hear it doesn't)

But minor inconvenience for me ... I'm just worried for those that need it.

 

[whiteco3]

Still happening on 1.8 for me. Oh well.

(Octopus, half hour periods. Ignore the time scale , it actually started at 00:30 as scheduled)

 

[julianm]

I’ll have to start paying attention to SoC when looking at the amperage.

This is normal as the fastest rate of charge takes place between 10-40%. Passed that threshold the charge rate usually decreases, mostly for battery preservation.

Edit to clarify: The above is what I just heard from CS, after months of pinging them that I was still having this “issue”.

 

[julianm]

I gotta say, the more I think about that answer from CS the more upset I get.

• This behavior for AC charging is not documented anywhere I can find.
• Yeah I know phones/computers do things like this but usually only when they see a regular schedule. And usually they charge at full speed to 80%, and then slowly after. 40% is not at all the same level of usefulness. I could see doing this when scheduled charging is enabled if this slower charging would still complete in time.
• I’ll verify this, but I’m pretty sure the Amperage drop coincides with recalculating the “charging complete” time, which means they are intentionally making the charging take longer than they initially show when plugging in.
• If I can’t complete a charge overnight on a road trip, I’m going to use DC fast chargers, which cannot possibly be better for the battery longevity than 40A charging instead of 26A charging. And it’s a waste of my time when I could’ve been 90% charged.

This has to be wrong - my car charges at a full 11kW on AC at any SoC unless I'm charging to 100% (which is very rarely) and even then it only tails off a bit at the end. That answer only seems reasonable to me for DC fast charging. I have a Chargepoint Flex hardwired on 70A and the car maxed to 48A and my charge line is always flat. The only problem I've had is the occasional 2/3 problem some folks also have, but it's pretty rare.

I hope it is, but Alane’s been back-and-forth with me on this for months. 26A would be ⅔ the 40A I’m supposed to be getting. It’s just Alane seems to be saying the ⅔ thing is intentional. I don’t really know what else I’m supposed to do here. Asking if something is a malfunction shouldn’t take this much work.

 

[GDank]

That's a stupid response.

Maybe at an extreme push an 11kw charge may be reduced to 7kw right near the end for the last few %, but I've seen my car charger from 90-100% at 7kw.

Probably someone answered who doesn't know shit about EV's and found that line in a manual.

If that statement was even remotely true then you would see a charging curve..... Mines been 7kw from start to end and still does it now most times.

I really dislike when a support line feels like they are reading from a manual and offer no real guidance.

I've never had this issue since Nov'20 until I got P1.7 update in Oct'21.
