摘要： 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.

摘要翻译： 随着时间的推移，可充电电池的扩展检测和补偿的方法和系统。 扩展检测器可以耦合到或靠近可再充电电池定位以监测其扩展。 在扩展超过所选择的阈值之后，扩展检测器可以将扩展报告给相关的处理单元。 处理单元可以通过修改或改变耦合到可再充电电池的充电和/或放电电路的一个或多个特性来进一步阻止进一步的充电电池膨胀。 例如，处理单元可以在检测到扩展后以较低的速率或降低的电压对可充电电池充电。
