Abstract
A method of monitoring a battery energy management system includes discharging a detector circuit to a minimum battery voltage, measuring an elapsed time that the minimum battery voltage is detected, resetting a timer circuit, and sampling the minimum battery voltage and the elapsed time of the minimum battery voltage in response to a predefined prompt. The discharge of the detector circuit, the measurement of the minimum battery voltage, the elapsed time of the minimum battery voltage, and the reset of the timer circuit are performed in response to an input voltage being less than the voltage stored within the detector circuit.
