My Model S Raven went to Tesla for an air conditioning repaire. A leak was detected and a new piece is ordered under warranty. This will be fitted 3 weeks from now and a message on the dashboard reads as below. Charging at home normally takes 5 hours and now 20 hours with 13 amps. Can anyone advise how much longer it takes on fast chargers? I have a 7.5 hour trip ahead of me and require 2 charging stops but questioning if I should use an alternative car. Comments appreciated
