EasySolar; can the battery temperature sensor from the charger be used to compensate the BMV SoC?

I have an Easysolar 48/5000/70-100 with CGX and seperate BMV 702.

I notice that there is an installed battery temperature sensor to the EasySolar, and I assume that is part of the charger (it is not the optional BMV one). I would like to know if it is possible to configure the system so that that temperature information feeds the BMV state-of-charge calculation?

Hi @Gavin Andrews,

not sure I understand your question correct. But the temperature information, be it from the EasySolar or the BMV, has nothing to do with SoC calculation.

SoC highly depends on measuring charge and discharge energy in and out of the batteries.

My layman's understanding is that battery capacity is affected by temperature. SoC is expressed as a percentage of capacity.
