I have a SR+ and have done about a dozen trips from Lake Tahoe to San Diego and back about 10 hours in a ICE car and 11.25 in my SR+
You really should never be charging past 70% (the exception being before climbing in sub freezing temps in the sierras) on road trips and instead plan to make much shorter charging stops more often. I’m normally out of a supercharger in 15-20 min if I precondition the battery before charging and it’s about the time my wife needs to stop for a pee break anyways so it’s kinda great to stop. Use the restroom and be ready to go again. If you are charging 45 min you are doing it so wrong.
