I'm planning on taking a trip to Yosemite National Park next weekend for the long holiday weekend. The trip is 3 days / 3 nights. Temperatures will be in the 20's and 30's, with high chance of rain and snow.
The hotel I booked inside the park does not have a level 2 charging station (or even a NEMA 5-15 level 1 outlet). My vehicle is a 2021 Model Y LR AWD.
The Groveland Supercharger is there at the base of the mountain, about 50 miles from Yosemite Valley. I'm planning on topping up to at least 90% there on the way up. According to A Better Routeplanner, it's a 1:30h trek up the mountain to the Valley, and arrival SoC will be ~69% (~20% SoC lost). However, I don't think it takes ambient temperature into account.
Once at the Valley, I'll be mostly doing short trips inside the Valley to access various trailheads. So the car will be mostly sitting still in the cold. There are two level 2 charging stations in the Valley, but I don't know of their condition. They are free to use for all guests in the Valley so they may or may not be working. Plus, it's the holiday weekend, so there will be a lot of traffic coming through. Once someone connects, I don't expect them to unplug for a good 6-12h, so I don't expect to rely on them.
Finally, on the return trip, A Better Routeplanner estimates 15% SoC needed to get to Groveland Supercharger from the Valley. Again, probably not taking ambient temp into account. So I need to make sure that I have at least 20% SoC (to be safe) left before the end of the 3rd day to make it back down the hill to Groveland Supercharger.
Assuming I arrive with 70% SoC, and need to go no lower than 20% to survive the trip back, will 50% SoC last me 3 days / 3 nights? The actual driving portion inside the Valley will be small (under 50 miles), but leaving the car sitting in cold temps is what bothers me. I'll also make sure to turn off Sentry Mode.
Will I survive? Or should I reserve a ICE rental vehicle for next weekend?
