    摘要： A method of charging a secondary battery and a charging device that can improve stability and extend the life span of the battery. When the secondary battery includes a plurality of cells, the charging method is changed when a voltage imbalance from 100 mV to 300 mV occurs among the cells. In that range, the charging method changes from a constant current-constant voltage charging method to a pulse-charging method. When the voltage imbalance is 300 mV or more, the electricity path is blocked, shutting down the battery. When the voltage imbalance is 100 mV or less, the constant current-constant voltage charging method is maintained. The method and device also stop charging when the battery reaches full charge.

    摘要： A battery pack, a charging system including the battery pack, and a method of controlling the charging system are disclosed. The battery pack includes a plurality of rechargeable battery cells and a protection circuit for protecting the battery cells. The protection circuit includes an analog front end (AFE) integrated circuit (IC) and a microcomputer. The AFE IC is for supplying an operating voltage of a microcomputer to the microcomputer and to a charging device. Thus, when the battery pack is charged, an abnormal operation of the AFE IC can be detected by the charging device and the charging of the battery pack stopped, thereby preventing an explosion of the battery pack.
