As described in several posts in the Bolt topic last week, I rented a new (54 miles on the odometer) 2020 Bolt on Turo last week, and drove it from the Bay Area via I-580/205/5/S.R.120/99/120/108 over Sonora Pass (9,624') to Lee Vining (6,780') and then up to Tioga Pass (9,945'), back to Lee Vining and then home by the same route. I couldn't take my usual route via 120 through the Park, but Oakdale to Bridgeport is probably very similar to Oakdale to Lee Vining as far as distance and energy use. I post the info here for anyone driving a similar size BEV to use as a basis for trip planning.
I collected energy use info along the way. I charged to 100% in Tracy, where there are EA, EVgo and CP QCs within a half mile or so of each other, and then topped to 90% in Oakdale, which is the furthest east dual QC on the way to Yosemite. There is a single CP QC at Rush Creek Lodge on 120, 20 miles east of Groveland, but as it's likely to be occupied by lodge guests even if it's working, I wouldn't depend on it. There's also a dual CP site in Groveland that's been waiting for a transformer for a year now, with no indication when that might happen. The only QC (not SC) on the east side north of Bishop is the EA site in Bridgeport, which I was unable to charge at (see Bolt topic). It took 8.3 kWh to get from Tracy the 37.9 miles to Oakdale. The rest of my numbers are between Oakdale (155') to Lee Vining and/or L.V. - Tioga Pass. I drove normally for me, somewhat fast, but used minimal amounts of A/C or heat.
Oakdale - Yosemite Junction: 25.1 mi./8.3 kWh
Yos. Jct. - Clark Fork: 55.9 mi./22.0 kWh
Cl. Fk. - Sonora Pass: 16.9 mi./10.0 kWh
_______________
Oakdale - Sonora Pass: 97.9 mi./40.3 kWh
Sonora Pass - Bridgeport: 31.5 mi./2.6 kWh
_______________
Oakdale - Bridgeport: 129.4 mi./42.9 kWh
Bridgeport - Lee Vining (Gus Hess Park L2 chargers): 25.8 mi./5.7 kWh. Note, drove 55-50-45 to ensure adequate reserve at Lee Vining, so figure 7-8 kWh at normal speeds.
________
Oakdale - Lee Vining: 155.2 mi./48.6 kWh
Lee Vining (G.H.P.) - Tioga Pass: 12.9 mi./7.2 kWh
L.V. (120/395 Jct.) - Tioga Pass): 12.0 mi./6.9 kWh
T.P. - 120/395: 11.9 mi./ (-)1.7 kWh
T.P. - G.H.P.: 12.8 mi./ (-)1.7 kWh
_________
G.H.P.- T.P. RT: 25.7 mi./5.5 kWh
120/395 - T.P. RT: 23.9 mi./5.2 kWh
G.H.P. - Sonora Pass: 56 8 mi./18.6 kWh
Sonora Pass - Yos. Jct.: 72.6 mi./3.3 kWh
Yos Jct. - Oakdale 25.1 mi./5.9 kWh
_________
G.H.P. - Yos. Jct.: 129.4 mi./21.9 kWh
G.H.P. - Oakdale: 154.5 mi./27.8 kWh
From Lee Vining to Yosemite Junction I averaged 5.9 mi./kWh, and 22 mi./kWh from Sonora Pass to Yosemite Junction!
