I recently got this error in the report from BimmerLink while scanning my 2014 60ah BEV and I'm curious if anyone knows particularly what it means:
21F137: HVS: Battery aging: SOH low (warning threshold)
The wording seems clear enough that the battery passed below a state of health threshold BMW considers significant but it's not obvious what that threshold might be.
For context, and various batt kapa max readings, I've been trying to document the battery health over the 6+ years I've owned the car here:
https://www.mybmwi3.com/threads/cha...-health-over-multiple-years.17163/#post-71233
But the snapshot is: currently batt kapa max is usually in the 14.4-15.1 range, and Electrified app says SOH is 80%. Car has approx 78k miles on it.
This car has become secondary in the household so it's still plenty for what I need, so I'm creating this thread out of a combination of curiosity and to hopefully help folks in the future because of the lack of results when I googled the error code.
