I see now this system is way smarter than I imagined. I followed your directions and it did exactly what I wanted. See attached.
1. How accurate is the planner as it compares to daily use and what folks are getting on the road?
2. Trying a few routes in the planner I noticed that at some superchargers you only "fill up" to 40-50% SOC. Is that common? Do people fill up all the way to 90% or go with the Planner's suggestions of a lower SOC?
3. Does the planner assume the "tapered" charging profile Tesla claims when at a Super Charger? What is it, like 50% SOC after 30 min?
I followed your directions and it did exactly what I wanted.
I'm sure this is obvious, and maybe you need that much juice when you get to Tahoe, but setting the Tahoe arrival as 88% means you need to leave Truckee with 97%, and charging above 90% is going to be slow. Might be worth seeing how much it reduces the charging time at Truckee (currently 1:02) if you drop the Tahoe arrival to 80% - presupposing that 80% at Tahoe is enough
1. This planner is extraordinarily accurate. I frequently go from 90% charge to 10% charge on one leg of a road trip, and the planner is accurate within 1-3%. My typical settings for my 85D are about 300 Wh/mile @ 65 MPH, 105% reference speed, and 75 MPH max speed.
2. Partial charges at Superchargers are not only common but actually ideal. The battery charges fastest in the lower range. Thus the entire mission of the planner is to minimize total time (driving + charging), and it does this by keeping most of your charging to the lower range of the battery.
3. Yes, the battery charging profile is exactly tapered as Tesla has illustrated, and the planner absolutely computes all time optimizations based on that taper profile. That directly leads to the planning that uses partial charges in the lower range of the battery.
So far just playing with routes, this is quickly becoming my favorite planner.
Question regarding the MyTesla hookup running the site in the car, does the system do real-time updates to consumption and speed and adjust charge times accordingly? Or add/remove charging stops if necessary along the way?
Glad to hear! With MyTesla logged in ABRP will continuously fetch your SoC and - after a few percent of SoC usage - estimate the actual consumption and reference speed. When/if the SoC differs more than to 2% from the planned SoC, a button labeled "Replan" will appear in the drive information window at the bottom. This will insert the calibrated values (visible in the "Details" drive information) and replan accordingly, which may completely change your route, add/remove stops and so on depending on what is optimal with the new values.
If you do not press "Replan", nothing will be changed in the plan. It is in your hands.
