Abstract
Disclosed is a maximum power point tracking charge controller for double layer capacitors intended for uses with non-ideal power sources such as photovoltaics.
Claims17
A energy system comprising a photovoltaic array, energy storage system, and a charge controller, wherein:
- said energy storage system is comprised of a least one electric double layer capacitor;
- and
- said charge controller is electrically interposed between said photovoltaic array and said electric double layer capacitor(s);
- and wherein said charge controller comprises a DC-DC switched-mode converter, a photovoltaic maximum power-point tracking algorithm, and a capacitor constant-power charging algorithm;
- and wherein the conversion ratio of the DC-DC converter is adjusted by the aforementioned algorithms, whereby the electric double layer capacitor(s) are constant-power charged as regulated by said DC-DC converter, while simultaneously the photovoltaic array power is maintained within a margin of the maximum power-point by said DC-DC converter.
