PROBLEM TO BE SOLVED: To make a voltage variation fall within a tolerable range even if the power consumption of an auxiliary machine is abruptly varied.SOLUTION: A power supply control device (i) sets a control target value of an output voltage of a generator low compared with the case that total power consumption a high-voltage auxiliary machine and a low-voltage auxiliary machine is not larger than a first threshold, in a first case that the total power consumption of is larger than the first threshold when a high-voltage secondary battery is separated from high-voltage wiring by a relay, and (ii) sets the control target value of the output voltage of the generator high compared with the case that the total power consumption of the high-voltage auxiliary machine and the low-voltage auxiliary machine is not smaller than a second threshold, in a second state that the total power consumption is smaller than the second threshold which is not larger than the first threshold when the high-voltage secondary battery is separated from the high-voltage wiring by the relay.SELECTED DRAWING: Figure 2
