Show charging state ie Charging or Discharging

I have the fuel gauge in the code and it works as expected. Since my device will be solar powered I would like to add code that would return a value of 1 for charging or 0 for discharging. I have looked through the forum and the Reference Documents but can’t locate this. Does anyone know if this is possible?
