I saw a formula for charge times to 80% on this site, which was, basically 80 minus current percent charge, times 3.65, divided by 60, equals hours to 80% charge level.
I find that with my home charger (Bosch) the multiplier is more like 2.5. Either the 3.65 number is in error, the Bosch charger allows a faster charge, or there is some other factor involved.
In any event it is curious.
 
Which model year (battery capacity)? At what amperage? Which country are you in (charging voltage)?

Any rule of thumb is going to be affected by those three variables.
 
2017 with 33kwh battery, in the U.S. on a level 2 Bosch charger. I understand this may be a moving target, but a formula was put forward, and I think it may be useful with some models and not others. I have found what works on my car.
