A low power supervisor controller for an electric vehicle substantially reduces ignition-off draw current in the main control module. The supervisor controller has a sleep controller for powering down the main control module when an interrupt event has not occurred. The sleep controller powers up the main control module when the interrupt event has occurred. The supervisor controller also has an interrupt monitor for determining when the interrupt event occurs, as well as a supervisor wait module. The supervisor wait module establishes and controls an interrupt cycle, wherein the interrupt cycle is defined by an amount of time between determinations of the interrupt monitor.
