A high-voltage auxiliary system for a vehicle includes a high-voltage battery, a temperature raising device, a high-voltage auxiliary machine, and an electronic control device. The temperature raising device is connected to the high-voltage battery via an electric circuit and raises the temperature of the high-voltage battery by utilizing fluctuations in voltage and current. The high-voltage auxiliary machine is electrically connected to the electric circuit and is driven by power supplied from the high-voltage battery. The electronic control device suppresses the operating state of the high-voltage auxiliary machine so that a fluctuation in voltage and current due to the operation of the temperature raising device and the operation of the high-voltage auxiliary machine is less than an allowable value of the high-voltage auxiliary machine.
