BYD SoC doesn't reach 100% - problem in temperature compensation?

I've noticed that one of my installations doesn't reach 100% SoC with sheduled charge.

Is it possible, that due to the low temperature MultiPlus compensates charge voltage but does not change the SOC correlated with the voltage?

Hello Zakhar,

I don´t think this is related to the temperature. It not only doesn´t reach 100% but also doesn´t reach 55.2v. Could you try increase this voltage to see if you can reach the calibration point?
