Abstract
A method includes detecting a voltage of the battery, detecting a current of the battery, determining a depth of discharge of the battery based on the voltage and the current of the battery, and controlling terminating charging of the battery responsive to the determined depth of discharge of the battery reaching a depth of discharge threshold. A system includes a battery gauge circuit and a processor coupled to the battery gauge circuit. The battery gauge circuit has a voltage sense input and a current sense input and is configured to determine a depth of discharge of a battery based on a battery voltage at the voltage sense input and a battery current at the current sense input. The processor is configured to control terminating charging of the battery responsive to the determined depth of discharge reaching a depth of discharge threshold.
