摘要:
A method of controlling the operation of a data flash and a battery pack capable of performing the method. In the method, writing, copying, and deleting operations are performed on two data flashes according to status flags recorded in predetermined respective locations of the data flashes. If one of the data flashes is full of data, it is possible to prevent a data flash failure from occurring when a part of the data is copied from the data flash to the other data flash or the data is deleted from the data flash.

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.

A charging control method for a battery pack including a plurality of battery cells in which a full charge voltage value is initially set as a first voltage value. The charging control method includes: charging the plurality of battery cells to the first voltage value in an initial charge mode; and resetting the full charge voltage value to a second voltage value less than the first voltage value in a subsequent charge mode.
