Abstract
Embodiments of the invention relate to a multi-cell battery, and individual evaluation of the battery cells. Each cell is individually removed or disconnected from the battery. An adjustable cell charger and an adjustable cell load are mapped to the disconnected cell. As the charger charges the cell, an associated sensor validates acceptance of the charge. As the cell load discharges the cell, the sensor measures discharge characteristics. Operating efficiency of the selected cell is evaluated based on the measured charge acceptance and discharge characteristics.
