Abstract
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.
