nice battery charger

This circuit is for battery charging. Main elements are: 1. Capacitor simulates the battery 2. Potentiometer 4 ohm simulates network or battery load 3. Potentiometer 2 kohm simulates battery charge current regulator 4. 5V source simulates voltage source from network Met assumtions are: 1. While battery is being charged changing load (potentiometer on left) doesn't affect buttery charging current 2. When network is being disconnected after buttery is fully charged (when orange trace is 0) then initially there is no change on load voltage (or almost no change) which is blue tarce but after that blue trace is being dropping If attempt to start simulation with closed switches causes 'Cannot find solution' then start simulation with open switches and close then in any order. If capacitor (battery) is not charged then fait for it to be fully charged and open switch next to 5V source - battery starts discharging. To do not cause app crash on simulation wait for blue trace to drop a little below 2V and close switch for 5V source.
