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.
Claims20
A method for a device to estimate battery health, comprising:
- collecting measurements of a battery over a plurality of charging and discharging cycles;
- assigning scores to the measurements according to scoring rules stored in a memory of the device;
- calculating battery health based on an average of the measurements, each measurement having an assigned score greater than a threshold;
- and
- updating the scoring rules and measurement rules based on an analysis of the measurements during lifetime of the battery, wherein the measurement rules are used to adjust trigger conditions that define when to collect the measurements.
