Welcome to the Guess O Meter. It truly is a Guess based on your recent driving. I almost wish it wasn't displayed. At the house, I charge when I see about 25% (quarter tank in ICE terms) as I do with my Pathfinder. On the one and only trip away from home, I hit the first charger along my route with 38% and charged to 90. I then charged when I got close to my destination because I wanted enough charge for the weekend. My "around home" rate is about 4miles/kWh but I also did a "loaded" test of 100 miles with 2 E-bikes on the hitch rack and 3 adults (about 750lbs) load. I only got about 3Miles/kWh on the test. That will be my weight for our September Trip and I loaded that along with a 10knot headwind into ABRP for my initial plan.
