METHOD AND APPARATUS FOR BATTERY CHARGE LEVEL ESTIMATION
First Claim
1. An apparatus for battery charge level estimation comprising:
- an energy harvester configured to convert non-electrical energy into electrical energy;
an energy storage apparatus, electrically connected to the energy harvester and configured to receive energy from the energy harvester;
a battery electrically connected to the energy storage apparatus; and
a processor configured to monitor the energy transferred from the energy storage apparatus to the battery and to monitor the energy delivered by the battery to a power-consuming component;
wherein the processor is configured to calculate a remaining life of the battery as a function of the energy transferred from the energy storage apparatus to the battery and the energy delivered by the battery to the power-consuming component.
