Currently at the Bend supercharger, where it is 57 degrees. My car was at Bachelor for the day, where it was colder, but it was almost a half hour drive to get to the supercharger, it does regenerative charging almost the whole way, so the battery should not be very cold. I am the only Tesla here, and I'm charging at 38kw!!
I switched stalls, thinking it must be the charger (from 1B to 2A). Still 38kw. Says it's gonna take a half 25-30 minutes to go from about 50 to 80%.
I feel like Tesla claims of 20-30 minutes from zero to 80, then another half hour to 100, were very misleading!! Maybe under completedly ideal circumstances, but not often.
With Model 3's not far away, I sure hope Tesla does something soon to fix this, although I doubt they will. They're not building superchargers fast enough, and the superchargers are too slow. I don't think that Model 3 owners are going to be nearly as understanding when they find how long it realistically takes to charge.
Maybe it's just the Bend supercharger, which seems pretty consistently slow. I might see high speeds (120kw) for the first minute or so, but it's then a steady decline towards 40-60. Yesterday, actually had to unplug it and plug in again when I noticed it had dropped all the way to 20kw! Plugging it in again brought the speed up to 60's.
I think Tesla, current owners, and future model 3 owners are all in for a rude awakening when Model 3's are out in significant numbers. I don't think the supercharger network is anywhere near ready for them. Really feel bad for those in CA!!
