I have had an update notice for my batteries to update from 3017 to 3020.

But as usual no release notes - so is 3020 new or has it been out for some time, and does anyone know whats new / changed ?

  1. Fix rare bug where Full capacity reset to 0 on battery restart
  2. Optimise internal resistance abnormal detection logic. Fix dynamic lower self calibration error
  3. Upper calibration logic optimisation above 80%. Where OCV was abnormally adjusting SOC downwards
  4. Add modified cell maps, to take into account higher charge currents at lower temps.
  5. Fix short Circuit detection logic, causes rare BMS Short-Circuit Error, when there was no actual fault present on battery restart.
  6. Pre-Charge Policy change, in conjunction with 5.

3020 is the latest new firmware

biggest change is point 4, previously the battery slowed down charging when temperature was 20 degrees, now that threshold is reduced to 10 degrees

Only on this Forum and thats it…

And it seems this is no longer maintained Low voltage firmware revisions | GivEnergy , and I did a google search and found nothing .

Hopefully the updates to an actual offical website will happen.

But no issues since the uprade.

Since I upgraded my battery to version 3020, it has had some problems which have become regular last weekend. I charge the battery in the morning and discharge it in the evening but the mobile and web apps show the battery stuck at 100% when discharging. I have to reset the battery to get the apps to notice that the battery is exporting its power. I looks like GivEnergy are going to recalibrate the battery.

it doesn’t help you - but mine is all working fine - App / Webpage and Home Assistant

But I did an Calibration last month - so maybe thats changes things.

I did this upgrade in consultation with a GE operative and they insisted a calibration was needed and so was actioned.
I’ve had no issues s8ncecthe upgrade

So with 3020, the battery charges at full rate down to 10 degrees, rather than the 60% between 10-20 of 3017 ?
