Can you give the English subtitle?

2:01 for that 40-80% range how can one overcome this issue for lpf chemistry? I am working on soc est usiing CC for LFP batt, but this part has got me worried . any suggestions ?

[@nexloop]

If you are using voltage based prediction for SOC estimation then it is a problem for LFP chemistry, as discharge profile for LFP chemistry is flat in the range of 40-80%.
In case of CC( Coulomb Counting) , it is based on charge ( coulomb ) and not voltage. So no need to worry, CC works in case of LFP chemistry.
