Abstract
A method for counting electrons from a power supply, comprising the following steps: measuring a current of a power supply forming a measured current; converting the measured current to a voltage; then into a monotonic uni-polar representation of an aggregate number of electrons having an amplitude; actuating a microprocessor in communication with a data storage just before an integrator in communication with the power supply reaches a preset limit of aggregate electrons; reading the amplitude forming a reading; transmitting the reading to an accumulator forming an accumulator value; resetting the integrator after the transmitting the reading, repeating the actuation, reading and transmission; comparing the summation of accumulator values to a calibration value; and recording the capacity when the summation of accumulator values meets or exceeds the calibration value.
