摘要： A battery charger includes a master charge manager, and a slave charge manager coupled to the master charge manager. The master charge manager is coupled to a power source and one battery and is configured to charge the one battery with a first continuously decreasing portion of the available current after a voltage across the one battery exceeds a first predetermined maximum voltage threshold. The slave charge manager is coupled to the power source and another battery and is configured such that, while the master charge manager charges the one battery with the continuously decreasing portion of the available current, the slave charge manager charges the other battery with a continuously increasing portion of the available current. The total of the decreasing portion and the increasing portion are substantially equal to the current available from the power source.
