I am charging my capacitor so it can act as a battery for a short period of time. I already did the calculations for the battery discharging and charging.
My problem is now that I have a load, I want to prevent current to flow to the load until the capacitor is fully charged (or to my required voltage threshold) so I can get maximum output power/energy. When the capacitor is fully charged, the charge controller stops its current flow and stops charging.
What kind of switch or relay do I need that can read, detect or sense my capacitor is full and then connect the capacitor to the load until capacitor drops below a certain voltage?
My load is a wifi module which I don't want current to flow to it and cause problems before I get the correct power or energy levels that are needed.
My Capacitor will have a around 56 Joules of capacity. My Load needs 1.65 Joules for 1 second, then only 0.1 Joules/sec This will get me around 6-15 Seconds of discharging til I hit my minimum voltage of the capacitor which is 0.9V.
I want to prevent any energy to go to my load until the capacitor is full.
