Abstract
A contaminated hydrogen charging preventing system that prevents contaminated hydrogen from being supplied to a vehicle. In particular, a sensor that is disposed in a charging pipe that charges a hydrogen tank of a vehicle with senses/detects contaminates in the hydrogen. Upon sensing contaminated hydrogen, a controller configured to control a cutoff valve is controlled to close charging pipe so that the contaminated hydrogen cannot be supplied to the vehicle. In addition, a hydrogen charging station may also terminate the flow of hydrogen to a dispenser based upon receiving contaminated hydrogen information from the controller within the vehicle.
Claims7
A contaminated hydrogen charging preventing system comprising:
- a sensor disposed in a hydrogen charging pipe for charging a hydrogen tank of a vehicle with hydrogen and configured to sense contaminated hydrogen;
- a cutoff valve controlling whether the hydrogen charging pipe is open or closed;
- and
- a vehicle charging controller configured to control the cutoff valve in response to a signal from the sensor.
A hydrogen charge station comprising:
- a dispenser that charges a vehicle with hydrogen;
- a charge station cutoff valve that controls a supply of hydrogen to the dispenser;
- and
- a vehicle charging controller configured to terminate the supply of hydrogen to the dispenser by controlling the charge station cutoff valve, upon receiving contaminated gas information from the vehicle.
A method of preventing a fuel cell vehicle from receiving contaminated hydrogen, the method comprising:
- receiving, by a controller within the fuel cell vehicle, a signal indicating that hydrogen being supplied to a charging pipe in the vehicle is contaminated;
- and
- closing, by the controller within the vehicle, a cutoff valve disposed in the charging pipe of the vehicle in response to receiving the signal from the sensor.
