Abstract
A method for refueling hydrogen fuel cell powered vehicles is disclosed, that is capable of automatically disabling the vehicle systems, resetting the vehicle systems to allow for normal vehicle operation after the refueling event is complete, and determining if a faulty refueling event has been detected and allows normal vehicle operation.
Claims20
A method for refueling a hydrogen fuel cell powered vehicle, comprising the steps of:
- (a). providing a vehicle system, a control system in electrical communication with the vehicle system, and at least one refueling sensor in electrical communication with the control system;
- (b). determining whether the vehicle is refueling using the refueling sensors;
- (c). generating and transmitting a vehicle refueling signal from the refueling sensors to the control system;
- and
- (d). disabling the vehicle system using the control system when a vehicle refueling signal is received.

A method of refueling a hydrogen fuel cell powered vehicle, comprising the steps of:
- (a). providing a vehicle system, a control system in electrical communication with the vehicle system, at least one fuel inlet sensor in electrical communication with the control system, and at least one fuel tank sensor in electrical communication with the control system;
- (b). determining vehicle refueling using the fuel inlet refueling sensor;
- (c). determining vehicle refueling using the fuel tank refueling sensor;
- (d). generating and transmitting a first vehicle refueling signal from the fuel inlet sensor and a second refueling signal from the fuel tank sensor to the control system;
- (e). disabling the vehicle system using the control system when a vehicle refueling signal is received;
- and
- (f) re-enabling the vehicle system using the control system when the refueling is complete.

A method of refueling a hydrogen fuel cell powered vehicle, comprising the steps of:
- (a). providing a traction drive system, a control system in electrical communication with the traction drive system, at least one fuel inlet sensor in electrical communication with the control system, and at least one fuel tank sensor in electrical communication with the control system;
- (b). detecting vehicle refueling using the fuel inlet sensor;
- (c). detecting vehicle refueling using the fuel tank sensor;
- (d). generating and transmitting a first vehicle refueling signal from the fuel inlet sensor and a second refueling signal from the fuel tank sensor to the control system;
- (e). determining a faulty refueling signal when the first refueling signal and the second refueling signal do not both communicate a refueling is occurring to the control system within a predetermined time period;
- (f). disabling the vehicle system using the control system when the vehicle refueling signal received is not faulty;
- and
- (g). re-enabling the vehicle system using the control system when the refueling is complete.
