Abstract: An electronic device. The electronic device may include a battery, and a charging system in electronic communication with the battery. The charging system may be configured to charge at least a partially-depleted battery to a threshold charge value, discontinue the charging in response to the battery being charged to the threshold charge value, and monitor the function of the electronic device to detect at least one of an anticipated event, and an unanticipated event of the electronic device. Additionally the charging system may be configured to recharge the battery in response to detecting one of: the anticipated event occurring a predetermined time subsequent to the recharging of the battery, or the unanticipated event occurring immediately before the recharging of the battery.

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.
