Abstract
Embodiments of the invention relate to a configuration of a multi-cell battery pack, with at least two cells electrically connected in a first parallel arrangement, which is connected in series to a second parallel arrangement of at least two additional cells. Each cell is locally connected to a sensor to sense and control the current of the cells in parallel or parallel-series combination in the multi-cell battery pack. A control module is in communication with each sensor, and associated instructions electrically remove or disable a cell from the multi-cell battery pack determined to be defective based on measurements from an associated sensor. Accordingly, the configuration measures and monitors a state of health of each cell in the multi-cell battery pack, the measurements including temperature, voltage and current sensing.
