Really wish this forum would post Stickies in the threads for commonly searched for information...I'll post what I've learned and I'm sure someone will correct me.
There are many variables for charging rates, which model you have(S/X3-SR/LR) temp outside, temp of battery, SoC(state of charge aka how much battery you've got left), the supercharger(s) if it's an Urban, V2, V3, how many other cars are plugged in... it goes on and on
Bascially, it comes to this. Select the Supercharger you want to go to and hit navigate. Your car will display "Pre-conditioning battery" which means it's either warming the battery or cooling it to the optimal temperature so it's able to accept as much charge as possible when the car arrives to the charger.
