Need your feedback. My system harvest renewal energy and store it to super-capacitor. I used super-cap so charging rate is fast.
The charge in the super-cap then can be used for charging battery pack such as li-ion or li-poly. Here's my system:-
multi sources (wind+solar+hydro+other) >>> controller (bq24650) >>> energy storage (supercapacitor ) >>> buck convertor (tps24231) >>>linear charger (bq24072) >>> battery ( li-ion/ li-poly)
