If battery SOH is at 100%.
Speaking from my own experience, the car’s historical data will be completely wiped cleaned.
From that point the BMS will have time to learn the actual condition / heath of the pack.
When my car received the update, like many the predicted mileage was 162 miles of range.
Over the next few months and charge cycles, the car starts to report a figure that takes into account of any battery degradation.
Cars that have covered only a small mileage will retain that 163 predicted range longer.
Mine has slowly reduced in its prediction until it has now returning what I believe to be the true SOH of the pack.
It now consistently returns a predicted range of 154 miles in normal mode.
The car is over two years old and covered over 18,000 miles.
A family member has a similar aged car, but it has only covered 7,000 miles.
His car is still reporting 163 after a full charge.
The degradation is minimal on his car.
Other owners have witnessed similar returns with similar age and mileage covered.
Just to say my car has only visited a rapid charger on three occasions for a very small “Splash and Dash”.
