This is par for the course on traction batteries. You need official dealer software to dial them in.
My VW Passat hybrid did not even let me change the cooling fluid myself because it is also used to cool the battery. In fact anything remotely tied to the high voltage battery is not user serviceable, and dealers are only allowed to replace instead of repair.
And this car is from 2015 so the enshittification started there already.
- alistairSH 11mo agoOur BMW is 100% dinosaur-burning. Just a normal 12V starter battery. Still needs OBD programming to change, even if the type/capacity remains the same.
- maxerickson 11mo agoIt seems that it tells the charge controller to reset the battery history? I would want to see a bit of data before concluding that it is useless to do that.
- matthews3 11mo agoI think for AGM batteries, it uses different charging curves depending on the age/health of the battery.
- alistairSH 11mo agoYes. Apparently ramps charge rates based on battery age. Which is fine and good, but shouldn’t require BMW software to do.
