    摘要: The disclosed embodiments provide a system that manages use of a battery corresponding to a high-voltage lithium-polymer battery in a portable electronic device. During operation, the system monitors a cycle number of the battery during use of the battery with the portable electronic device, wherein the cycle number corresponds to a number of charge-discharge cycles of the battery. If the cycle number exceeds one or more cycle number thresholds, the system modifies a charging technique for the battery to manage swelling in the battery and use of the battery with the portable electronic device.

    摘要: Some embodiments of the present invention provide a system that charges a battery. During operation, the system obtains a set of charging currents {I1, . . . , In} and a set of charging voltages {V1, . . . , Vn}. Next, the system repeats constant-current and constant-voltage charging operations, starting with i=1 and incrementing i with every repetition, until a termination condition is reached. These constant-current and constant-voltage charging operations involve charging the battery using a constant current Ii until a cell voltage of the battery reaches Vi, and then charging the battery using a constant voltage Vi until a charging current is less than or equal to Ii+1.

    摘要: A method and apparatus are described for monitoring a battery in an electronic device. In the described embodiments, a discharge current pulse is applied to a battery and the voltage change of the battery due to the discharge current pulse is determined. The impedance of the battery is then determined based on the voltage change and the discharge current pulse. An alert is then selectively generated based on the impedance.
