    Abstract: A battery management method and apparatus. In one embodiment of the method, a source current is divided into Ic and Icr. Ic is transmitted to and charges a battery. A first voltage is generated that is related to Icr. The first voltage is converted into a first digital signal. A processing unit receives and processes the first digital signal in accordance with instructions stored in a memory. The transmission of Ic to the battery is interrupted in response to the processing unit processing the first digital signal. Current provided by the battery is divided into Idc and Idcr. Idc is transmitted to a device. A second voltage is generated that is related to Idcr. The second voltage is converted into a second digital signal. The processing unit receives and processes the second digital signal in accordance with instructions stored in the memory. The transmission of Idc to the battery is interrupted in response to the processing unit processing the second digital signal.
