Abstract: 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.

Abstract: An electronic device may include a battery, and a charging system in electronic communication with the battery. The charging system may be configured to initiate a charging of the batter when the battery is in a partially-depleted state. The charging system may then discontinue the charging in response to the battery being charged to the threshold charge value, and may monitor the function of the electronic device to predict an event of the electronic device. After the event is predicted, the charging system may determine when to initiate a recharging process, so that the battery is fully charged when the event occurs.

Abstract: Methods and systems for detecting and compensating for expansion of rechargeable batteries over time. An expansion detector may be coupled to or positioned proximate a rechargeable battery to monitor for expansion thereof. After expansion exceeding a selected threshold is detected, the expansion detector may report the expansion to an associated processing unit. The processing unit may undertake to arrest further rechargeable battery expansion by modifying or changing one or more characteristics of charging and/or discharging circuitry coupled to the rechargeable battery. For example, the processing unit may charge the rechargeable battery at a lower rate or with reduced voltage after detecting expansion.
