ABSTRACT:
A system for measuring a battery voltage is provided. The system includes a battery, a time encoding circuit, and a controller. The time encoding circuit is in electrical communication with the battery to receive the battery voltage. The time encoded circuit is configured to generate a time encoded signal corresponding to the battery voltage. The controller is in electrical communication with the time encoding circuit to receive the time encoded signal and configured to determine the battery voltage based on the time encoded signal.
