Abstract: A device estimates the health of a battery by first collecting measurements of the battery over multiple charging and discharging cycles. Scores are assigned to the measurements according to scoring rules stored in a memory of the device. The device calculates battery based on an average of the measurements, where each measurement has an assigned score greater than a threshold.

Abstract: Methods are provided to be able to efficiently and precisely estimate/predict an available capacity of a battery. One method is arranged to estimate/predict the available capacity of the battery according to a first battery percentage result, a second battery percentage result, and a calculated power when the battery is being operated or used within a specific operating range distinct from a normal operating range. Another method is arranged to estimate the available capacity by measuring battery's internal resistance and referencing a precise battery aging model.
