I have a battery which supplies a true-sinewave inverter, and I'd like to measure the battery conductance/resistance/impedance/admittance in situ.
The inverter current varies as I=Io.sin^2(ωt) almost reaching zero around the zero crossings of the inverter output voltage.
I have a current shunt and a voltage divider connected to A/D inputs, to measure the battery current and voltage.
Does anyone have a neat algorithm that could derive the battery conductance?
