摘要： A method is provided for controlling a discharge of a battery pack that supplies power to a portable electronic device. The battery pack has one or more cell blocks each having a plurality of battery cells connected in parallel. The method includes the following steps. Determining, for each of the one or more cell blocks, a value of a first supply current flowing through a first battery cell that has the smallest capacity among the plurality of battery cells. Comparing, for each of the one or more cell blocks, the value of the first supply current with a first overcurrent value of the first battery cell to detect overcurrent in the first battery cell. Generating, in response to detecting the overcurrent in the first battery cell of any of the one or more cell blocks, a first overcurrent signal to reduce the power supplied to the portable electronic device.
