Abstract: A precharge control apparatus starts precharge of a capacitor. The precharge is determined to be completed when a set time has elapsed since a voltage difference between a battery voltage and a capacitor voltage detected by a voltage sensor becomes equal to or less than a set voltage. The set voltage is based on a maximum error obtained by adding maximum values of detection errors of the battery voltage and capacitor voltage by the voltage sensor. The set time is based on a time from when the voltage difference becomes twice the maximum error to when the voltage difference becomes equal to or less than a withstand voltage of a main contactor, under states where the precharge causes the capacitor voltage to increase with a time constant when a resistance value of a resistor and a capacitance of the capacitor each are largest within an allowable error.
