A power management system is provided for a vehicle having an internal combustion engine adapted to deliver power to vehicle drive wheels for propelling the vehicle and an engine powered component powered by the engine. The system includes a battery, a battery powered component powered by the battery, the battery powered component and the engine powered component being adapted to perform substantially the same functions, and a controller arranged to stop operation of the engine powered component so that additional engine power is available to the drive wheels, and to initiate operation of the battery powered component, when power sought to be delivered to the vehicle drive wheels from the engine reaches a predetermined percentage of maximum engine load.

A heating element protection apparatus for a mass-flow sensor may include a heating element disposed in a gas, a gas temperature sensor disposed in the gas to sense a temperature of the gas, a slope detector to measure a slope of the temperature as power is supplied to the heating element, and a heating element controller to supply power to the heating element to replace heat dissipated by the gas. The heating element controller may detect a temperature of the heating element and may supply power to the heating element based on the heating element temperature and the gas temperature, and the power may be switched off for a predetermined period of time if a magnitude of the slope is greater than a reference magnitude.
