With BMS enabled, my ford charges at higher voltage (14.0 - 14.8) during downhills and deceleration, and around 12.6 and 12.4 at cruise, temperature dependent. The oem setting targets 80% state of charge, as set by the factory.
I played with it for a while and eventually defeated it for a standard float voltage of 14.0-14.4.
So, 80% SOC is not unheard of.
Note - I’ve lost somewhere between 0.6-1 mpg since disabling BMS.
That change in MPG doesn’t seem realistic, though I could obviously be wrong. Once the battery is fully charged the amp draw is almost nothing.
Now, if you’re short-tripping a lot, causing a frequently depleted SoC, then there are many others more likely factors for such a degradation in mileage.
