Abstract: A battery management system and a driving method are provided. The battery management system performs a bleeding operation at a moment that a voltage of each cell becomes a reference voltage during an initial charging operation to smoothly change a slope of a charge voltage. Accordingly, the charging time of the cell initially charging at the low voltage is increased, thereby reducing the entire cell balancing period.
