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.
