Abstract
A minimum reference voltage and an operation inhibiting reference voltage are set as the criteria for detecting the conditions of power supply of a low voltage power source system including a low voltage battery. The operation inhibiting reference voltage is lower than the minimum reference voltage and represents a threshold value ensuring the normal operation of an apparatus that establishes the power source of a high voltage power source system. When the power source voltage of the low voltage battery is lower than the minimum reference voltage but is not lower than the operation inhibiting reference voltage, a converter is activated to charge the low voltage battery to the minimum reference voltage whole system of, for normal functions. When the power source voltage of the low voltage battery is lower than the operation inhibiting reference voltage, on the other hand, operation of the whole system is inhibited.
