Abstract
The measured capacity of a rechargeable battery provides the full charge capacity of the battery, but does not reflect degradation of the battery capacity between measurements. Embodiments initiate a first measurement of a rechargeable battery capacity. Parameters of use of the rechargeable battery are monitored, such as the depth and number of discharge cycles of the battery. Until a second capacity measurement is initiated, a battery capacity correction factor is generated based on the monitored parameters of the use of the rechargeable battery. During this interval until the second measurement, a remaining available capacity of the rechargeable battery is reported based on an adjustment of the first capacity measurement using the generated correction factor. The correction factor for a particular battery may be based on learned battery degradation for a large number of batteries and also based on events and conditions of use of that particular battery.
