I'm not so sure. The two cars on this thread that have the lowest deterioration numbers are the two that regularly charge at around 2kW. The sample size is too small to make any confident conclusion, but having a third car in that sample seems a good idea. I too am considering swapping out my E VSE that only charges at 32A to one that allows multiple settings (32A when I want to charge 'normally', and much lower when I am happy to let it charge all night or all weekend.)notfred wrote:...I think you are overly cautious only charging at 6A, ....

My car had a change in deterioration numbers at 148 occations. The Min det was #8 in 76%, the Max det was #2 in 28% and 22% had both as above.
Coincidence..? Probably, but...

I drove fast over the mountain 110km/h, decelerating hard before the speed cameras. Very unusual driving speed and style for my car.
There was a spike up in my readings a month ago. It occurred immediately after driving fast 100km/h over a mountain.
The Min and Max reading initially reversed. This is the second time I have seen this in 3 years.
Both times were driving fast over the mountain.
It is something I rarely do, so I doubt this is coincidental.

Today, I was at a fast c harger (haven't been there for at least 2 months) and checked the values again: 18.3/18.3/18.4 (Max/Avg/Min). And yes, Min was higher than Max, which is very strange.
I was shocked to loose almost as much capacity as during the entire last year with 20,000 km. Hopefully, just the BMS is mis-calibrated and will recover after the next calibration.

And yes I think the deterioration values on your car will go back down just like mine did.
ToyToyToy wrote:Now that you mention it.... just before I took the reading I was driving quite fast, 130-140 km/h, for 15 minutes or so, since we were late for an appointment. This probably caused the drop of the values.
So - any thoughts on how my stats compare to the cohort of other Soul EVs?
