Reading with interest...
We mostly charge at home on the granny lead, (unless there's some rush) and have found that recently it stops at 97/ 98%, although it's set to charge to 100%. Last night, it was left plugged in for over 16 hours and still did not reach 100%. Also, we haven't set up the app, so we can remove that as a potential factor.
fwiw... '23 Trophy LR
Now fully charged (kind of), it is estimating its total range will be 200mi. Not sure why we've lost 50 miles of range, she's only 6 months old. (trying not to care too much, as I know... I know... it's just an estimate. have I been lead-footed recently? I will neither confirm nor deny).
Charging rate on the granny seems to be somewhere around 20% per 5 hours in nice weather, and the worse it gets outside, the longer it takes.
I'm getting worried by this seasonal deterioration... if we needed to travel more than 100 miles in a week, we'd have to re-think our strategy. In all the changes I expected going from petrol to EV, I had not anticipated how detailed of a "strategy" we would require just to operate the car on a weekly basis.
