An onboard high-voltage system includes a temperature-increase device, a high-voltage auxiliary device, an electronic control unit. The temperature-increase device is connected to the high-voltage battery through an electric circuit. The temperature-increase device is capable of executing a battery temperature-increase operation to increase a temperature of the high-voltage battery by turning on and off a switching element included in the temperature-increase device to charge and discharge the high-voltage battery. The high-voltage auxiliary device is connected to the electric circuit, and is driven by power supplied from the high-voltage battery. The electronic control unit executes a warm-up operation to warm up a smoothing capacitor included in the high-voltage auxiliary device or the temperature-increase device prior to the battery temperature-increase operation, and prevents a voltage fluctuation or a current fluctuation during the battery temperature-increase operation from exceeding a tolerance value of each component in the high-voltage auxiliary device.
