Hi Everyone,
I have a site with 2 battery banks, and I have 2 units of BMV-712 (one per each).
However, the BMVs have been calibrated when the batteries were full, but I found out later that the BMV readings are different from the real SOC
E.g. the SOC was 80% on BMV, however, on it was 20% on the batteries themselves.
What should have made this critical difference? Why the BMV is not giving the correct state of charge?
The batteries are Li-ion and each bank has 15 units of 100Ah).
Kindly advise.
