Additional BMS frames

[towe96]

Two new-ish developments, I analysed the BMS software for the 17s batteries (TC, TS, CUX) and found a screenshot of yet another program that's supposedly able to read all the data in the TC Maxs battery.

As for the 60V vehicles:

C5 5C 5A AA 01 97 96 0D "query data"
C5 5C 5A AA 01 98 98 0D "query voltage"
C5 5C 5A AA 01 99 99 0D "query version"

And here's a screenshot from the other program:

I haven't had any luck tracking this down, but one user on Facebook (who offers paid remote diagnostics...) mentions it's a dealership software and he's also able to clear the LOCK flag (presumably an undervoltage BMS shutdown).

The screenshot implies that it's all communicating on the same bus (9600 Baud, bottom left), so I might start trying my brute force attempts again later in the year.

Hi @towe96 , thanks for sharing the insights.
I have read such information somewhere else a few years ago, so there is a good chance that the data strings (commands) you have shared are correct. If I remember correctly, it will return the information for each cell as one response each. But please don't pin me down on that one :)
I will later add the information to a new section "unverifed" in the documentation.
