Abstract
Official abstract text for this publication.
A hydrogen filling method for a fuel cell vehicle includes filling a hydrogen tank of the fuel cell vehicle with hydrogen using a hydrogen dispenser by sequentially using a low-pressure storage tank of the fuel cell vehicle, a medium-pressure storage tank of the fuel cell vehicle, and a high-pressure storage tank of the fuel cell vehicle.
First claim
Opening claim text (preview).
What is claimed is: 1. A hydrogen filling method for a fuel cell vehicle, the method comprising: filling a hydrogen tank of the fuel cell vehicle using a low-pressure storage tank when there is an infrared (IR) communication error between a hydrogen dispenser and the fuel cell vehicle; filling the hydrogen tank using a medium-pressure storage tank unless hydrogen stored in the low-pressure storage tank feeds into the hydrogen tank; filling the hydrogen tank using the high-pressure storage tank unless hydrogen stored in the medium-pressure storage tank feeds into the hydrogen tank; and completing the filling of the hydrogen tank unless hydrogen stored in the high-pressure storage tank feeds into the hydrogen tank, wherein the fuel cell vehicle monitors a temperature of the hydrogen tank through a hydrogen control unit while being filled with hydrogen, and outputs a warning signal when the temperature of the hydrogen tank exceeds a threshold value. 2. The method according to claim 1 , further comprising determining whether or not the hydrogen stored in any of the low-pressure storage tank, the medium-pressure storage tank, and the high-pressure storage tank moves to the hydrogen tank using a flowmeter. 3. The method according to claim 1 , further comprising maintaining a first reference pressure in the low-pressure storage tank through a compressor. 4. The method according to claim 1 , further comprising maintaining a second reference pressure in the medium-pressure storage tank through a compressor. 5. The method according to claim 1 , further comprising maintaining a third reference pressure in the high-pressure storage tank through a compressor.
