    摘要: A vehicle engine starting system that drives a starter motor engaged to start an engine by using a lithium secondary battery as a power source comprises a voltage sensor that detects a voltage at the secondary battery and a control device that allows power to be discharged from the secondary battery to the starter motor if the voltage at the secondary battery detected by the voltage sensor is equal to or higher than a predetermined value and disallows a discharge from the secondary battery to the starter motor if the voltage at the secondary battery detected by the voltage sensor is lower than the predetermined value.

    摘要: A power supply system includes: a high voltage power supply; a main power supply wire; a step down circuit inputting a power having a high voltage and outputting a power having a lowered voltage; a sub-power supply wire; a voltage sensor for sensing a voltage of the power outputted from the step down circuit; a sub-switching element disposed on the sub-power supply wire; and a controller for controlling the sub-switching element. The controller turns off the sub-switching element, when the voltage sensed with the voltage sensor is equal to or higher than a first predetermined voltage defined lower than the lowered voltage. Moreover, the controller drives the sub-switching element in duty control for stepping down the power having the high voltage to the power having the lowered voltage outputted from the step down circuit, when the voltage sensed with the voltage sensor is lower than the first predetermined voltage.
