Ah, I see. Then I think you may be comparing apples and oranges -- in my experience ABRP is not doing the right thing with charge curves and cruise speed, which is dependent on a large number of unknowable factors at the planning stage anyway (e.g., temperature, wind). The default settings also assume you are traveling at the speed limit, which it sounds like you are not. Roughly, you get about 20% lower range by traveling at 80mph (80mi, 25 kWh, 3.2mi/kWh) vs 60mph (60 mi, 15 kWh, 4mi/kWh), and then lose another 20% going from 80mph to 90mph (90 mi, 35 kWh, 2.6mi/kWh). [0] Peak charging speed is 250kW and is sustained from ~5%-~35%, and then tapers. Charging from 10%-60% is typical, and takes about 13 minutes for about 38 kWh, meaning that each kWh you use adds about 20 seconds of charging. [1] We can integrate these into the speeds and consumptions above to construct effective speeds that account for the charging time required. E.g., at 60 mph you travel 60 miles in an hour, consume 15 kWh of energy, and thus spend 5 minutes charging -- 60 miles over 65 minutes is about 55 mph. nominal -> effective speed (efficiency): 60 mph -> 55 mph (92%) 70 mph -> 62 mph (90%) 80 mph -> 70 mph (88%) 90 mph -> 75 mph (83%) 100 mph -> 80 mph (80%) - whee! So even though you spend more of your travel time charging at higher speeds, your effective travel speed continues to go up well into speeds you're probably not cruising at. In other words, that peak "optimized cruise speed" for a modern EV that can charge 38 kWh in 13 minutes (~175 kW) is well above what you're probably driving anyway. For comparison, if you stop for 5 minutes every 3 hours in your ICE to refuel, at 80 mph you've got an effective speed of 77 mph, about 10% faster than your EV at 80 mph. (The above scenario has you stopping every 1.5h at 80mph in the 75 kWh-capacity EV; of course, you could stop less frequently but with a bit of a hit to your effective speed assuming 0 stop overhead.) Not making any normative claims here about what's better, etc. -- just laying out the numbers as I see them!
