I'm on my 3rd battery charge with the new battery. The dealer tech and everything I've read online said to discharge down below 25% to help car learn the new battery capacity faster.

1st Charge
When I picked up the car from the dealer the range read 200 miles
SoC (Display) = 100%
SoC (RAW) = 100%

I drove it 191.2 miles and used 49.5 kWh of juice.
94% driving / 5% HVAC / 1% Battery Conditioning
Remaining range = low
SoC (display) = 9.4%
SoC (Raw) = 13.4%


2nd Charge
Charged it up and the range read 218 miles
SoC (display) said 100%
SoC (Raw) said 96%


I drove 190.8 miles and used 46.8 kWh of juice
91% driving / 7% HVAC / 2% Battery Conditioning
Remaining Range = 46 miles
SoC (Display) = 22.7%
SoC (Raw) = 27.2%


3rd Charge - In Process

It will be interesting to see what the range meter says tomorrow with a full charge. The car does seem to be learning the battery has more capacity.

On the 1st charge the car thought 49.5 kWh was 90.6% of the usable capacity. That calculates to 54.6 kWh usable capacity

On the 2nd charge the car thought 46.8 kWh was 72.3% of the usable capacity. That calculates to 64.7 kWh usable capacity.
