Abstract:
1. A starting device for a high-voltage component of a fuel cell vehicle comprising a fuel cell stack and a 12 V battery, the device comprising: a low-voltage motor coaxially connected to a high-voltage motor as a high-voltage component, wherein the high-voltage motor is connected to a first shaft; a clutch mounted on a second shaft connecting the high-voltage motor and the low-voltage motor; and a controller configured to supply a current from the 12 V battery to the low-voltage motor or to supply a current generated by the fuel cell stack to the high-voltage motor, wherein the controller is configured to cut off the current from the 12V battery to the low-voltage motor when the current is being supplied to the high voltage motor, wherein the low-voltage motor is coaxially connected to a rear of the high-voltage motor through the second shaft and the clutch is coaxially mounted on the second shaft between the high-voltage motor and the low-voltage motor so that a rotational force of the low-voltage motor is transmitted directly to the first shaft of the high-voltage motor through the clutch.
