CVL much too high #1094
Comments
What I see in your log is:
Please try also the latest nightly and enable |
Make sure to install the nightly, since it contains a fix in combination with |
The nightly is now running with the fix, so far so good. No abnormalities so far. 👍 First of all, thank you very much for the quick help =) |
Could you try to change
to 3.500 , so we see, if the value is comming from there.

Can you also write me on Discord? You find the link by clicking on my profile. |
Today one of the three battery blocks went from float to bulk. Unfortunately, again the CVL is too high. I don't use Discord, I could offer email or WhatsApp. |

Describe the bug
There is a massive problem with version v1.3.20240705.
The CVL is wrong and almost shot my cells.
Both the latest 1.3.20240705 and the nightly build etc. are affected.
Apparently the software reads CVL from the BMS (max cell voltage).
In Serialbattery I set 3.45V (bulk) and 3.35V (float) as the maximum voltage, but serialbattery still takes the full 3.65V from the BMS. When the cells reach this voltage, the value jumps back and forth. This means that it charges briefly at full power, then overshoots to 3.6V/cell and then immediately discharges again. I'm now reinstalling an old version, the problem didn't exist there.
Or am I doing something wrong?
I have a 16s system and that would be a total of 55.2V CVL at 3.45V. With float it would still be 53.6V.
Here you can see the 58.4V CVL....
How to reproduce
cvl that is too high is constantly displayed...
Expected behavior
What is expected is a cvl similar to the "old" version, i.e. maximum cell voltage * number.... in my case 3.45V * 16 = 55.2V
