ABSTRACT:
A battery monitor for use with a battery includes an input configured to receive a voltage from the battery, an analog to digital converter (ADC) coupled to the input and configured to convert analog voltages received through the input into digital indications of levels of the analog voltage, and a processor coupled to the ADC to receive the digital indications of the levels of the analog voltage of the battery and configured to manipulate the received digital indications to reduce inaccuracies introduced by the ADC in the received digital indications of the levels of the analog voltage relative to actual levels of the analog voltage during discharge of the battery, the processor being further configured to provide an output indicative of a determined level of the analog voltage.
