Just wanted to share that I drove down from Portland, OR to Yosesmite without any problems!
This was my first trip using the super chargers and I was carrying my 3yo and 1yo daughters, so I was a bit nervous. But thanks to http://evtripplanner.com I had ample confidence about what to expect in terms of rated range and in fact each segment ended up using only about 80% of the estimated range provided from the website.
Here are some of the stats:
Portland, OR -> Springfield, OR (skipped Woodburn SC)
Estimated: 162 miles range
Actual: 120 miles range used (74%)
Springfield, OR -> Grants Pass, OR
Actual: 168 (72%)
Grants Pass, OR -> Mount Shasta, OR
Actual: 157 (78%)
Mount Shasta, OR -> Corning, CA
Actual: 110 (70%)
Corning, CA -> Vacaville, CA
Actual: 150 (76%)
Vacaville, CA -> Fremont, CA
Actual: 95 (81%)
// I stayed in San Jose with family and then headed over to Gilroy for a full charge
Gilroy, CA -> Wawona, CA (destination)
Estimated: 246 (!!!)
Actual: 178 (72%)
I'm now getting ~3.3 miles per hour trickle charging at a cabin (rented by the Redwoods Cabins). With 67 miles to spare pulling in to the driveway, it only took 2-3 days to get the full charge necessary to get back to Gilroy and head back up to Portland.
I'm sharing this because there aren't too many stories of trips to Yosemite/Wawona and I wanted to help give future travelers confidence that it's easily doable from Gilroy. Some additional details about my trip:
- My conservative estimates were assuming 1.3 speed factor, 90 degree outside, 68 degree inside, and 600 pounds of weight.
- On the final Gilroy -> Wawona leg, I stayed close to the speed limit the entire time, just to be safe.
- Oddly, when I arrived in Oakhurst to do some shopping, I had 89 miles of range left. When I got back in the car after an hour of shopping, it said 105 miles of range! The temperature outside was ~92F.
- Going uphill obviously kills range. I found I could do much better if I allowed myself to decelerate slightly on the uphill and then regain my speed on the downhill.
- I kept Range Mode enabled the entire trip.
- The only two super chargers that weren't entirely empty were Fremont and Gilroy. Fremont had pretty slow charging (~100mph) while Gilroy still went pretty fast despite all the cars there.
Anyway, I hope this gives future Yosemite visitors the confidence to take their Model S!
