MBB Firmware V39
« on: December 25, 2024, 03:14:39 AM »
Well, Zero has done it again.  They've released a firmware update, MBB V39, with absolutely no documentation.  Zero, if you're reading this, get your shit together.  Version descriptions should be released BEFORE the software release, not weeks after.

WEEKS??  I installed a firmware fix to my 2021 SR MONTHS ago and the page hasn't been updated yet as to what it does. I've written to them as well and have yet to get a response.

Today I received a reply from Zero Tech Support about MBB firmware V39.  Here are the changes:
1.  Resolving a bug that caused the state of charge (SoC) to drop shortly after completing a charge.
2.  Enhancing the range estimation algorithm for downhill travel.
3.  Fixing a logging issue related to reported charge temperature.

These changes are STILL not posted on Zero's website, so I hope this post helps those, like me, who want to know what's involved with a firmware change before accepting it.

Website STILL not updated. At least now I know what MBB V39 addressed but I still don't know what BMS V46 addressed.

Made a check with the Next Gen app yesterday and the MBB version 41 is ready to download. I am awaiting the details before upgrading. My SR/S is actually at MBB MBB V39, BMU V17. If anyone has more info, let us know. Thanks
