SOH after HVJB update(is this normal)

[g8mb1t]

Just wondering if anyone knows if this is normal battery degradation after 3 years? 19000m, limited DC fast charging.
Also I believe that the SOH only updates if you either update the modules or run the battery down to 10% and charge it up to 100% again.

exactly the same for me ! 92.5 %. It's going down after the battery's power-up OTA.

As a comparison, my calculated (not reported) SOH on my BMW i4M50 is almost exactly the same at around 92-93% after 22k miles. The HVB typically drop off early but then stay mostly stable for many (100k+?) miles based on what I read.

With ~2,000 miles on the odometer, the alleged HVB SOH of my car was 96.5 (it was in the middle of winter, might have been one point or so higher had the weather been warm, based on the fluctuations I have seen going through seasons in the last three and a half years). At 64,000 miles three years later it was 91 until the HVBJB replacement; after the recall the alleged HVB SOH dropped to 85 - a six point drop that had nothing to do with reported Energy to Empty at 100% or the effective driving range - then slowly climbed to 87 over the next two months. The odometer is at 72,000 miles now and I haven’t bothered looking for the past month or so. Most charging has been done on L2, but I have no hesitation in using DCFC on road trips and average 20-25 DCFC visits per year.

Thanks for sharing this is great to know. They must have changed the SOH algorithm.
