Here are preliminary results for a trip model I've been working on for the Bolt EV. This one starts in downtown LA and goes to downtown SF. The distance to Harris Ranch is ~197 mi, so this trip is a little shorter than yours. The distance from Harris Ranch to SF is 183 mi, which coincidently matches your second leg distance.
Some assumptions for this are:
Preliminary energy efficiency and battery charging models
65 mph in "urban areas" (first 39mi, last 55 mi)
75 mph everywhere else
Good weather (no wind, rain, snow, etc)
No HVAC use (Edited: was "Mid HVAC use, 1.5kW continuous")
No elevation changes (No regen losses down the Grapevine)
Planned discharge no lower than 15% SoC
CCS stations are installed in Castaic, Lebec, Grapevine, Buttonwillow, Harris Ranch, and Gustine (NONE of these exist today!)
Charging at 125A max (don't have any >50kW Bolt EV charging data to model)
With these assumptions, you cannot
drive the Bolt EV over this route with only one stop.
It is doable with two stops (Buttonwillow & Gustine) but you have to recharge all the way to 95% at Buttonwillow, which adds 24 minutes over a three-stop trip.
The fastest trip is done with three stops as shown at Buttonwillow, Harris Ranch, and Gustine. This is 5 hr 17 min of driving plus 1hr 46 min for charging including a short allowance for charging prep. The three charging sessions are 30 min, 30 min and 34 min sequentially.
