Systems and methods for monitoring deterioration of a rechargeable battery

摘要

Systems and methods are provided for monitoring the deterioration of a rechargeable battery. A battery monitoring system may be used to store charging information, discharge information and storage information for a rechargeable battery to a data store. The charging information may include a number of charge cycles incurred by the rechargeable battery. The discharge information may include a number discharge cycles incurred by the rechargeable battery. The storage information may include information relating to periods when the rechargeable battery is not being actively charged or discharged. The battery monitoring system may be further used to determine an amount of deterioration of a battery performance characteristic based on the stored charging information, discharge information and storage information.

主权项

1. A method performed by an electronic device configured to be powered by a battery, the method comprising:
monitoring battery usage habits in using the electronic device, wherein the usage habits include how often the battery is charged; predicting remaining usable life of the battery based on the usage habits by approximating an amount by which the battery's equivalent series resistance (ESR) has degraded over time; and displaying an indication of the remaining usable life of the battery in terms of time, wherein the displaying includes displaying an image that comprises:
a first representation of an initial capacity of the battery,a second representation of the approximation of the amount of deterioration of battery capacity relative to the first representation,a third representation of remaining capacity of the battery relative to the first representation, anda fourth representation of the remaining usable life of the battery relative to the third representation.
