CONTROL METHOD AND SYSTEM FOR STARTING OF FUEL CELL VEHICLE

摘要

A control method and system for starting a fuel cell vehicle is provided. The method includes setting a first output power that is an output power required for driving the vehicle and beginning to increase the fuel cell temperature after setting the first output power. In addition, available output power of a fuel cell is estimated and a discharge power of a high-voltage battery is received. A second output power that is a sum of the available output power of the fuel cell and the discharge power of the high-voltage battery is calculated. The method further includes determining whether the second output power is greater than the first output power and determining whether starting of the vehicle is allowable based on the determination of whether the second output power is greater than the first output power.

主权项

1. A control method for starting a fuel cell vehicle, comprising:
setting, by a controller, a first output power, which is an output power required for driving; beginning, by the controller, to increase the fuel cell temperature after setting the first output power; calculating, by the controller, a second output power by estimating available output power of a fuel cell and receiving a discharge power of a high-voltage battery, the second output being a sum of the available output power of the fuel cell and discharge power of the high-voltage battery; determining, by the controller, whether the second output power is greater than the first output power; and determining, by the controller, whether starting of the vehicle is allowable based on the determination of whether the second output power is greater than the first output power.
