Problems solved by technology
Since the expansion data of the hydrogen storage tank is not considered during the replenishment process of the hydrogen storage tank, the safety of hydrogen filling and the reliability of the tank cannot be guaranteed
In addition, hydrogen storage tanks require frequent comprehensive inspections, which incurs significant tank inspection costs
In addition, because the safety of hydrogen filling and the reliability of hydrogen storage tanks cannot be guaranteed in real time, the mass production of plastic hydrogen storage tanks is limited

The present disclosure provides a system and method for safely charging hydrogen using real-time hydrogen tank expansion data. The system includes an expansion measurement unit, a vehicle-side control unit, a charging station-side control unit, and a wireless communication unit. The expansion measurement unit is disposed on a hydrogen tank of the vehicle, and measures the degree of expansion of the hydrogen tank and generates a corresponding output signal. The vehicle-side control unit converts the output signal into data wireless output signal. The charging station-side control unit stops hydrogen replenishment by a hydrogen charger when the wireless output signal indicates an unsafe degree of tank expansion based. The wireless communication unit is provided to perform wireless data communication between the vehicle-side control unit and the charging-side control unit.
Description
technical field [0001] The present invention relates to a system and method for safely replenishing hydrogen into a hydrogen storage tank of a fuel cell vehicle. More specifically, the present invention relates to a system and method for more safely replenishing hydrogen into a hydrogen storage tank of a fuel cell vehicle using real-time tank expansion data. Background technique [0002] Generally speaking, a diesel locomotive is driven by the rotational power of an internal combustion engine produced by burning fossil fuels with oxygen in the air, while a fuel cell vehicle is driven by the rotational power of an electric motor generated by a fuel cell stack Electric energy to drive. A fuel cell stack, which is a power source of a fuel cell vehicle, generates electric energy by electrochemically reacting hydrogen supplied from a high-pressure hydrogen storage tank or reformer with oxygen in air supplied from air supply equipment such as a blower or a compressor. [0003] I...
