Abstract
An apparatus and a method of indicating safety of a hydrogen tank when a vehicle fire occurs are provided. The apparatus includes a hydrogen storing tank and a thermal pressure relief device (TPRD) mounted within a valve of the hydrogen storing tank. In addition, a controller is configured to detect a flow rate of hydrogen discharged from the hydrogen storing tank, using a sensor to determine whether the detected flow rate of discharged hydrogen is within a predetermined reference flow rate range. The controller is also configured to transmit a warning signal when the detected flow rate of discharged hydrogen is included within the predetermined reference flow rate range.
Claims18
An apparatus for warning safety of a hydrogen tank when a vehicle fire occurs, comprising:
- a hydrogen storing tank;
- a thermal pressure relief device (TPRD) mounted within a valve of the hydrogen storing tank;
- and a controller configured to:
- detect an occurrence of the vehicle fire;
- determine an expansion of the TPRD when a detected flow rate of hydrogen discharged from the hydrogen storing tank is within a predetermined reference flow rate range;
- transmit a warning signal in response to determining the expansion of the TPRD:
- and transmit an access prohibition signal in response to determining the TPRD is not expanded to prevent an explosion risk.
A method of warning safety of a hydrogen tank when a vehicle fire occurs, comprising:
- detecting, by a controller, an occurrence of the vehicle fire;
- determining, by the controller, an expansion of a thermal pressure relief device (TPRD) when a detected flow rate of hydrogen discharged from the hydrogen storing tank is within a predetermined reference flow rate range;
- transmitting, by the controller, a warning signal in response to determining the expansion of the TPRD;
- and transmitting, by the controller, an access prohibition signal in response to determining the TPRD is not expanded to prevent an explosion risk.
A non-transitory computer readable medium containing program instructions executed by a controller, the non-transitory computer readable medium comprising:
- program instructions that detect an occurrence of a vehicle fire;
- program instructions that determine an expansion of a thermal relief pressure device (TPRD) when a detected flow rate of hydrogen discharged from the hydrogen storing tank is within a predetermined reference flow rate range;
- program instructions that transmit a warning signal in response to determining the expansion of the TPRD, and program instructions that transmit an access prohibition signal in response to determining the TPRD is not expanded to prevent an explosion risk.
