Abstract: In embodiments, an apparatus may include a battery life monitor. The battery life monitor may, in some embodiments, receive a battery level indicator indicative of a current charge level of a battery that is coupled with the apparatus and a first temperature that may indicate a temperature of a current location of the apparatus. The battery life monitor may also receive one or more additional temperatures that indicate respective temperatures of one or more locations in which the apparatus is likely to be operated prior to discharge of the current charge level of the battery. Based at least in part on the current charge level, the first temperature indicator, and the one or more additional temperatures, the battery life monitor may calculate one or more battery life estimates that correspond with the one or more locations. Other embodiments may be described and/or claimed.

Abstract: Because a rechargeable battery has an increased number of uses (e.g., cycles), the battery's internal impedance can increase and the efficiency of the battery can become degraded. This internal resistance can cause cutoff voltage thresholds and cutoff current thresholds to prematurely stop a phase of battery charging, as these cutoff values can be based on low-cycle count batteries. New cutoff values can, instead, be based on battery impedance. Use of an adjusted cutoff current threshold during a constant voltage cycle can increase the capacity of high-cycle count batteries. Use of an adjusted cutoff voltage threshold in step charging can increase the charging speed of high-cycle count batteries. These increases in efficiency by using adjusted cutoff values can increase as the battery is further high-cycle count, in comparison with low-cycle count cutoff values used with high-cycle count batteries.

Abstract translation: 由于可再充电电池具有增加的使用次数（例如，循环），所以电池的内部阻抗可以增加并且电池的效率可能降低。 该内部电阻可以导致截止电压阈值和截止电流阈值，以过早停止电池充电阶段，因为这些截止值可以基于低周期计数电池。 相反，新的截止值可以基于电池阻抗。 在恒定电压循环期间使用调整的截止电流阈值可以增加高周期计数电池的容量。 在步进充电中使用调整的截止电压阈值可以提高高周期计数电池的充电速度。 与高周期计数电池一起使用的低周期计数截止值相比，通过使用调整的截止值，这些效率的提高可以随着电池进一步高周期计数而增加。
