Abstract
A smart battery provides electrical power and reports remaining capacity of the battery. A disparity between the calculated remaining capacity and the actual capacity of the smart battery is calibrated through a maximum power consumption mode. Specifically, a maximum power consumption mode is set, the battery is discharged until a battery capacity learning level is reached, the battery capacity is determined, and the system is then set to a minimum power consumption mode. Power management function is disabled prior to the latter process, and enabled after the process is completed.

12. A method of calibrating a capacity of a rechargeable battery providing power for a portable electronic system, the method comprising the steps of:
-
discharging the rechargeable battery; determining whether a discharge level at which the capacity of the rechargeable battery can be learned is reached; when it is determined that the discharge level at which the capacity of the rechargeable battery can be learned is not reached, continuing to discharge the rechargeable battery until the discharge level at which the capacity of the rechargeable battery can be learned is reached; and determining the capacity of the rechargeable battery when the discharge level at which the capacity of the rechargeable battery can be learned is reached; wherein the portable electronic system includes a power management function, and wherein the method further comprises the steps of disabling the power management function before said determining step, and enabling the power management function after said determining step. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21)
