ABSTRACT:
An energization control apparatus for a glow plug includes a battery, a glow plug, a power control unit, and an energization controller. The glow plug has a low rated voltage which allows rapid heating at a low battery voltage during cranking of a diesel engine in a severe wintertime condition. The power control unit is arranged between the battery and the glow plug to control a power supplied to the glow plug. The energization controller controls the power control unit so as to equalize a root-mean-square value of a voltage applied to the glow plug to be the low rated voltage when a voltage applied to the glow plug at the start of the diesel engine is detected to be higher than the low battery voltage.
