The latest research is that the average EV battery degrades at just under 1.8% per year (average mileage), and so after 14 years should still be able to hold 75% charge.
The same study reported that the average EV battery will probably last better than the average ICE engine.
Does the heating affect the range?

Will be interesting to see if once this becomes established in the minds of car buyers the impact on second hand values. A friend just bought a very nice 21 plate Tesla 3 for £23k. Seemed like a lot of car for the money.

How does a heat pump work:
In addition to my EX30, I have a Tesla M3. I have observed that even though both have heat pumps, the Tesla is much more efficient at producing heat.
Today the OAT was 12 degrees, yet I had to put the heating on to 28 degrees to get even a reasonable temp in the cockpit of the EX30.
In the Tesla - I wouldn't be able to sit in the cockpit after a while @ 28 degrees!
Must simply be down to the design of Volvo's heat pump, I guess. Disappointing though.

This post refers to all modern cars that I have ever sat in, not just Volvos, and certainly not just the EX30.
I have come to the conclusion that all car manufacturers are treating us like mugs in relation to cabin temperatures.
We all know hot air rises. So the air should normally be warmer nearer the roof than nearer the footwell (Unless there is a big noisy fan hidden in the glass sunroof to blow it all down again.) If we set a temperature, where it's it measured? Even if the measurement is correct, it only applies to one small part of the car.
Secondly, they now allow us to set two different temperatures, one for each side of the car. So do they have two thermometers, on in each side? Or does it just take one temperature and just estimate how to vary the heat flow to achieve the desired result?
If the natural air temperature outside is 22 degrees, the driver chooses 16 degrees, and the passenger 28, what happens? Is there a cooler trying to cool the drivers air while a heater tries warm the passengers air? And how does the car stop the cold and hot air mixing? I have yet to see a car with an air tight barrier between the occupants, and I have never been able to reach across to the passenger side and feel a marked difference in air temperature. If the car doesn't stop the air mixing successfully, neither driver nor passenger gets what was promised.

So you’re admitting that after 4 years your Tesla S lost say 9% of range? It’s still not good enough!iHansz wrote: ↑Thu Sep 26, 2024 2:10 pm "Over 3 years your battery will also lose 20% range." That is absolutely not true. The Dutch equivalent of your magazine Auto Express regularly does battery degradation tests of EVs and it all turns out to be tremendously better than expected. There are KIAs with 100,000 km and about 5 years old with still 97% battery capacity. Tesla does even better, at e.g. the Model S with more than 200,00 km on the odometer and more than 90%. Even with fast charging, battery capacity is not decreasing faster. My previous car with only 25,000 km on the odometer and 4 years old, still had more than 90% of its original capacity when sold in.
My Model 3 Long Range would charge to 100% when new in 2021 would offer ‘360’ miles worth of claimed range. When it was replaced by the EX30 (which was 6 months late) hence 42 months old, would only ever charge to 301 (actually more than 20% reduction in range.
I used to be able to London and back on a single home charge 138 miles each way at 70MPH with say 15% spare. By the end, I had to stop at a supercharger either on the way there or back for 10 minutes to guarantee the distance!
