First Claim
1. An electronic device comprising:
- an interface for receiving a battery comprising a battery module for supplying power to the electronic device; and
a power management module coupled to the battery and configured to;
measure an electromagnetic radiation spectrum of the battery due to current flow in the battery module;
compare the measured electromagnetic radiation spectrum of the battery to at least one of a plurality of reference electromagnetic radiation spectrums, each of the reference electromagnetic radiation spectrums corresponding with a different relative condition;
determine a relative condition of the battery by comparing the measured electromagnetic radiation spectrum with one of the plurality of reference electromagnetic radiation spectrums;
store, in a memory store, data identifying the relative condition of the battery;
repeat measuring the electromagnetic radiation spectrum, comparing the electromagnetic radiation spectrum, and determining the relative condition of the battery at a second time such that a second relative condition of the battery is determined;
compare the second relative condition of the battery with the relative condition of the battery previously stored in the memory store;
determine a rate of change between the second relative condition of the battery and the relative condition of the battery previously stored in the memory store; and
determine if the rate of change exceeds a threshold tolerance level.

Abstract
In at least one embodiment, a power management module measures an electromagnetic radiation spectrum or a voltage response of a battery module. The measured electromagnetic radiation spectrum or voltage response of the battery is compared to a plurality of reference electromagnetic radiation spectrums or voltage responses, respectively, which may be determined for authentic batteries, for example. A relative condition of the battery, such as an age or state of health, may be estimated based on the measured electromagnetic radiation spectrum or voltage response of the battery module, and stored in a memory store. The rate of change of the relative condition of the battery over a period of time may be determined to identify potential defects in the battery.
