I am used to charging NiCd or NiMH cells however I haven't done it
from a solar panel before. I'm happy I can hold the solar panel near
the point of peak efficiency but I am concerned about charge
termination due to the variable power available from solar panels.
Normally for NiCd I would use negative delta V for termination with a
back up timer. For NiMH I would use a thermistor for delta T
termination. However I can see potential problems with solar as the
power source.
In principle I could lay out a 60W panel in Arizona and charge the
batteries without problems - until someone parks a truck and shades
the panel dropping the charge current.
So what is the best way to terminate charge on nickel based batteries
with a variable power source?
