Abstract
A distributed charge controller that matches a charging and power profile of each individual battery cell within a bank of batteries with one or more strings of photovoltaic (PV) cells in order to maintain battery health and performance. The charge controller further optimizes the performance of a solar module by allowing active unshaded strings of cells to operate independently of other strings within the module that may be shaded. Strings of PV cells are selectively matched to one or more battery cells as required.
Claims20
A distributed charge control system comprising:
- one or more photovoltaic (PV) modules producing a current, each PV module comprising one or more strings of PV cells connected in series;
- a charge controller comprising a processor, memory and control electronics;
- a battery bank comprising a plurality of battery cells connected in series;
- and wherein the charge controller selectively connects each string of the one or more strings of PV cells to selectively charge one or more of the battery cells based on predefined logic.
