The present disclosure provides an alternative, cost-effective safety feature for on-board hydrogen storage containers incorporating a fill cycle sensor with a driver warning and shutdown system. The system monitors the number of times a hydrogen container is filled, and then takes action at a predetermined termination point. A controller monitors each time the hydrogen container is filled above 90% of the rated pressure or mass. Once the predetermined termination point of fill cycles is reached, the disclosed device/method will either disable the valve or refueling mechanism such that fuel supply to the vehicle is shutoff and the container cannot be filled again, essentially assuring the end of the life of the container.

What is claimed is: 1. A safety warning and shutdown system for a hydrogen storage container comprising:an on-board valve assembly fixedly attached to the container, the valve assembly having a check valve for filling the hydrogen storage container, an electrical solenoid, a pressure transducer configured to measure pressure within the hydrogen storage container, and a temperature transducer configured to measure temperature within the hydrogen storage container;a sensor to monitor a number of fill cycles; anda shut-off device to disable the valve assembly and prevent further use of the hydrogen system after reaching a pre-determined limit for the number of fill cycles.
