Abstract
Provided is an electric power system mounted on a vehicle having an engine, a battery, and a starter that starts the engine. The electric power system includes an SOC estimation part, estimating the SOC of the battery based on a first algorithm; an idling stop control part, permitting implementation of an idling stop control when an estimation result of the SOC estimation part satisfies a predetermined automatic stop condition; a full charge determination part, determining whether the battery is in a full charge state based on a second algorithm different from the first algorithm; and a malfunction determination part, determining that malfunction occurs in the SOC estimation part when the battery is estimated in the full charge state by the full charge determination part and the estimation result of the SOC estimation part does not satisfy the automatic stop condition.
