yes, the service doc explains that, when power is removed from the IBS, upon reconnecting it goes into an automatic calibration phase where it determines the parameters for the connected battery. It does this during a certain amount of time, and a number of start cycles. During this time it assumes a number of default parameters.
Nowhere will you find any mention of setting battery parameters. With the latest IBS sensors, this is apparently an automatic process....
from service description:
When the IBS is powered up for the first time or is powered after a power disconnection, it enters a
“recalibration” phase,
where the IBS must recognize the type of battery and its characteristics and state. In
this phase the tolerances on the state functions (SOC, SOF) are greater than in normal working condition.
When IBS is disconnected from the battery, the device loses its stored memory. When power is restored,
the IBS starts a relearn process. Until the relearn process is complete, accurate battery state information is
unavailable to other vehicle systems. The IBS relearn process requires one start and at least 4 hours of
quiescent time (vehicle off, electrical system asleep). Remember, the relearn process is restarted every
time power is reconnected to the IBS. This has a major effect on the stop/start feature.
But maybe there's something hidden in Witech..... It's not in MES
Of course the standard range of batteries is not that big, either 80 or 95 Ah, AGM or EFB
