I am not an electrical engineer but I have an observation that baffled me. So I have a 2020 MSP. I have FUSC so I charge the car at a 20 mile away SC. Last time I charged to 90% from 4% (much lower than usual). After charging then I toggled the battery from % to miles it said I had 304 miles. We were going to visit my wife's sister the next day which uses approx 250 miles round trip. So when I got home the previous night I topped off with the Tesla V3 Wall connector. stopped at 90%. The next morning when I toggled from % to miles it said 321 miles. That is real close to what I was getting when the car was new at 90%.

Well here is my question from that observation. Could the cell BMS be triggered on low SOC or a combination of low and high SOC. One for the experts.

Just a data point.
