We've discussed how there's a tradeoff between lessening LFP battery degradation (don't charge to 100% often) versus preventing BMS decalibration (charge to 100% frequently), but I haven't found any information on how bad the BMS calibration might get.
Here's the experiment I'd like to see someone do (perhaps a YouTuber):
1. Keep the SOC between, say 40% and 70% for a thousand(?) miles.
2. Drive until the car runs out of charge.
That may show how "off" the BMS calibration gets. Does it run out of charge when the display is showing 20%? Does the car have lots of charge left even when it is displaying 0%? Does the displayed SOC suddenly change as it gets low?
You get the idea. Perhaps something like this has been done, or maybe you can come up with a better experiment.
