Abstract
A battery management circuit maintains voltage balance during charging and discharging of a multi-cell, series connected battery stack. The circuit allows the entire energy content of the battery stack to be drained, as opposed to just monitoring the cells and turning off the discharge when the first cell voltage drops below a predetermined threshold. The circuit also provides high efficiency voltage balancing during charging of the battery stack conserving energy and keeping the temperature of the battery pack to a minimum.
