To provide a high-voltage auxiliary machine system capable of preventing component failure and life deterioration of a high-voltage auxiliary machine.SOLUTION: The high-voltage auxiliary machine system that is mounted on a vehicle comprises a high-voltage battery 10, a temperature raising device 21, a high-voltage auxiliary machine 30, and an electronic control device 35. The temperature raising device 21 is connected to the high-voltage battery 10 via an electric circuit 40 and raises temperature of the high-voltage battery 10 by utilizing voltage and current variations. The high-voltage auxiliary machine 30 is electrically connected to the electric circuit 40 and drives the electric circuit by power supply from the high-voltage battery 10. The electronic control device 35 at least either suppresses an operation state of the high-voltage auxiliary machine 30 or cuts off the electrical connection between the high-voltage auxiliary machine 30 and the electric circuit 40 so that the voltage and current variations due to the operation of the temperature raising device 21 and the operation of the high-voltage auxiliary machine 30 become less than an allowable value of the high-voltage auxiliary machine 30.SELECTED DRAWING: Figure 5
