1. A method, comprising:
- monitoring, at a processor, a capacity of a battery, in which the step of monitoring comprises;
counting electrons flowing through the battery;
determining whether the electron count has reached a predetermined number;
activating a storage device to add the electron count to a total count after the determining step indicates the electron count has reached the predetermined number;
resetting the electron count after the determining step indicates the electron count has reached the predetermined number; and
determining the capacity of the battery from the total count;
reporting, to a remote monitor, the capacity of the battery through a network; and
reporting, to a user of the remote monitor, the capacity of the battery through a graphical user interface.

Abstract
The remaining capacity of a battery may be monitored with a microprocessor by integrating a voltage measured across a current sense resistor coupled in series with the battery. The microprocessor may measure electrons passing through the battery by sampling the integrator and summing the values recorded from the integrator. Each time the integrator is sampled, the microprocessor may reset the integrator to prevent the integrator from saturating. The remaining capacity of the battery may be calculated based on calibration values and the sum of electrons measured by the integrator. The remaining capacity may be communicating to remote users through a network and displayed in an executive dashboard.
