ABSTRACT:
The present invention relates to a microprocessor controlled battery management system that optimizes the total electrical capacity of that battery. It uses localized cell power sources that correct the capacity of the individual connected cells to achieve the maximum capacity of the battery as it acts in a synergistic series connection of cells. The microprocessor retrieves data of battery load current, cell voltage, cell temperature, and battery charger current in timed increments. Through the application of the microprocessor's algorithms, after an initial cell profiling of individual cell capacities has been performed, individual cell DC/DC converters are enabled to correct the condition of the individual cells. In this manner the battery capacity is not affected by the capacity of the weakest cell.
