Tip of the day:
If you are supercharging, select the charger on the map and navigate to it, even if it is a well known destination.
Turns on battery preconditioning magic... This can be confirmed with a notification on the route / direction display overlay on the map.
If you are 5 mins away like I am, drive for 10-15 mins. I think from what I have read the process takes 15-20 mins.
Was able to go from 20% to 100% in around 50 mins at a V3 charger. A previous attempt at super charging without this step was very significantly slower.
@emx does this also improve destination charging speeds esp at mid to high %age range?
