Abstract
A battery management system for a motor vehicle is disclosed. The system includes at least one battery having multiple battery cells, an automotive electronic control unit including a device for sensing battery quantities, where the battery quantities are the battery terminal current, the battery terminal voltage and a measured or estimated battery or battery box temperature, the battery terminal current, the battery terminal voltage, the measured or estimated battery or battery box temperature, and an automotive alternator supplying a regulation voltage, where the automotive electronic control unit is adapted to drive the battery through a charging cycle, in which a certain charge voltage and/or a certain charge current is supplied to the battery to charge the battery, and the automotive electronic control unit is adapted to control the regulation voltage based upon the sensed battery quantities to supply the certain charge voltage and/or the certain charge current to the battery.
