Working Principle of a Hydrogen Dispenser
- Storage: Hydrogen from the electrolyser is stored in pressure banks (low, medium, high).
- Connection: User connects the nozzle to the vehicle.
- Dispensing refueling: starts with the lowest-pressure bank, progressing to medium and high-pressure banks sequentially.
- Cooling:Hydrogen is pre-cooled to -20°C or -40°C (as per SAE J2601) using a chiller and heat exchanger for optimal gas density.
- Monitoring: Tank pressure and temperature are continuously monitored.
- With IR sensors, the tank is filled safely without exceeding limits.
- Without IR sensors, the SAE J2601 table-based method adjusts for vehicle data, ambient conditions, and pressure ramp rates, ensuring safety and efficiency.
