A unique system for the implementation of a multi cell battery pack whereby the individual cells are organized in different configurations for discharge or charging operation is presented. Battery pack discharge operation utilizes a series (stacked) configuration capable of producing a high output voltage necessary for the application. In contrast, charging operation configures the individual cells into a parallel (single layer) organization offering a simple fast charge operation provided by natural current sharing of the cells. Switch over between the two configurations is achieved using switching array implemented by low-cost N-channel MOSFET devices. Usage of dual modes for battery charge/discharge operation offers a simplified implementation with the highest performance. An application is also described where the present invention is used as a compatible replacement of a standard 12V lead acid automotive battery.
