Hi all. I wrote about this a month or so ago during the cold times when all of a sudden it had lost 10% just parking up. I know the temperature had an impact and i know the range etc...
I have been keeping a close eye on it but I don't drive it enough, and today, after morning school run I got home with 57% left, and when I left again on afternoon school run it had 44% , so the 13% disappeared into thin air (car was untouched) . And I got home after the 5 mile round trip with 37% left. The way I drive the zs , my "consumption " is at least 3.5mi/kWh constantly, may be even 3.8 at times. So the 5 mile trip I expect around 3% of usage and not 7
Also it was very strange that I had a lot of miles out at 62% (it was stuck at 62% for a very long time, probably 10-15 miles)
So my conclusion is that I either have a duff battery (which I am not sure if the dealer can check) or the LFP flat line behaviour makes it unpredictable for battery capacity in the middle. So I guess the drop of voltage for that few % around the 62% was so little that the car could not measure and after that it just dropped so much to make up the lost of the previous.
I guess if I repeatedly try from 100%-20% in this kind of weather (high singles low tens) and see if my mileage coverage is about the same or not. Treating it like an ICE with a faulty fuel gauge but knowing roughly how much I can get out of a full tank scenario.
I do not rely on the range, as I only consider % against mi/kWh
Thanks all
