Abstract: To suppress the occurrence of system shutdown after long term storage of batteries. A semiconductor device comprises a control unit that controls charging and discharging of a battery cell, and a ROM that stores a power supply capability value which specifies a power supply capacity of the battery cell that can be stably supplied to an application system in which the battery pack is provided. After the battery pack returns from the sleep mode and before the transmission request of the power supply capability value is received from the system, the control [unit performs a power supply capability value updating process of updating the power supply capability value in the ROM to a value smaller than the power supply capability value before the sleep mode.

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.
