Not true. There is a safety buffer built into the battery to prevent over charging so getting it up to 100% is just fine.The reality is supposedly 80% charge on a daily basis is better anyway FWIW
Rather than argue over the truth I'll suggest you believe the Fiat display of 100% is really the max safety amount and perhaps it is - that is not true of our Tesla and some others, but I will admit to not knowing if the E tries to hide the complicated notion of the safe buffer zone.Not true. There is a safety buffer built into the battery to prevent over charging so getting it up to 100% is just fine.
Does anybody know how much of the 24kWh is usable?........
0% indicated isn't really 0%
100% indicated isn't really 100%
The 500e has a "24kW battery" but you'll never get 24kW out of it, nor will you ever be able to put 24kW into it.
If you haven't already, I would try resetting the car via 30-second 12V disconnect.all of a sudden it’ll stop at 95%... charging again to 100%, .. indication will drop about 7% after the car is simply parked at work for the day.
Just in case you mean you haven't verified if your car has the latest software, you can check at https://www.mopar.com/en-us/my-vehicle/recalls/search.htmlThe latest Fiat software ... I have no way to verify it.
