I got in my car yesterday charge was reading 53% drove 5 miles, stopped, started again charge was reading 23% I then drove back and then this morning moved car to charge it and it said 47% remaining.
What on earth is going on? I know not to trust the range estimate but surely the car knows what the charge state is?

I assume you are the same person on Facebook with the exact same question?

Basically something is odd ... could be a temp glitch and it will sort itself out in time ... or a real issue and you'll need to take it to Volvo. However see how it goes over the next week and try drive it some more longer distances than a few miles.

Yes I thought it would be a reasonable thing to give it wider coverage

If you did a 5 mile drive from 'cold' with heating, wipers and your heavy boots on it is conceivable that the average consumption for the trip was very high. The software then took that usage, calculated the cars projected range, then took that figure and compared it the fantasy total range figure to decide that equated to 23% battery left?

Clutching at straws there and just guessing!!

If it did that then someone is guilty of crazy programming. It is meant to use SOC to calculate miles remaining, not the reverse!

The estimated range which is dependant on average power useage is notoriously inaccurate (and I chuckle at the 270 mile range at full charge). However per cent charge should be just that. One of my colleagues had an I-PACE with bad cells, the car in start up would interrogate the battery and decide how much of it could safely use and consequently give wide variation in range at full charge. It could be interesting (and I’ve got a plan a b and c).

It’s fully charged and won’t start. It says it’s empty but won’t charge. Not great

12 volt battery problem? You might get a temporary fix by jumping the 12-volt battery under the frunk.

I’ve not had any issues with the 12V battery before and the car has had all the fixes. I’ll try it again tomorrow (fortunately I’ve got a “spare car” so used that). I suspect/hope that the lost charge will miraculously reappear

And another problem....
I got in the car fully charged yesterday. Cabin preheating on etc
Drove 109 miles and during that the capacity dropped like a stone. I crawled to my destination with 8% charge left. The car then took approx 40 kWh to charge to 98%. The car trip computer shoes that it had used approx 40kWh on the journey.
The car had presumably calculated that its total capacity was 45kWh at startup either because of bad cells or a software fault.
I have asked polestar to investigate

I have a colleague who had a very similar problem with his I-PACE -in which the BMS looks for bad cells at start up and disables that bank of cells. He had an entire new battery pack
