I own a 2022 Model Y and I’ve never had a 15m charging stop. It’s always longer. 15m is theoretical. In the real world everything from temperature to the type of charger to how many people are charging at the station to the age of the battery impact speed. You’re looking at 25-40 mins on average to 80%. Double that to charge to 100%. I’m not sure why people feel the need to gaslight non-EV owners. The technology is what it is.
