Abstract
A method of testing a battery of a portable electronic device, the method implemented by the portable electronic device or battery-testing apparatus thereof, the method comprising: applying a measurement signal to at least one terminal of the battery, wherein the measurement signal is a fluctuating or alternating electrical signal; and obtaining a measurement of a mechanical response of the battery to the measurement signal from a sensor.
Claims18
A method of testing a battery of a portable electronic device, the method implemented by the portable electronic device or battery-testing apparatus thereof, the method comprising:
- applying a measurement signal to at least one terminal of the battery, wherein the measurement signal is a fluctuating or alternating electrical signal;
- obtaining a measurement of a mechanical response of the battery to the measurement signal from a sensor;
- diagnosing a state of the battery based on a relationship between at least one frequency spectrum or peak/dominant frequency or frequency of the measurement signal and the corresponding measured mechanical response;
- and
- dependent on the diagnosed state of the battery:
- adjusting a charging profile or algorithm for controlling charging of the battery dependent on the diagnosed state of the battery;
- or
- generating an alert or setting an operating state of the portable electronic device.
