摘要：

Focusing on the 70 MPa type Ⅳ hydrogen storage tanks used in hydrogen fuel cell heavy trucks，this study employs numerical simulation methods to analyze the temperature rise patterns and temperature control strategies during the rapid refueling process of large-capacity 70 MPa type Ⅳ hydrogen storage tanks. The results indicate that a lower hydrogen filling rate can reduce the temperature rise of the tank but will increase the filling time；higher ambient temperatures to be unable to reach the full state of 90% to 100% at the end of refueling；lowering the hydrogen pre-cooling temperature can significantly reduce the temperature rise of the tank，but will increase the cold energy consumption of the hydrogen refueling station；a linear pressurization mode and the pre-cooling mode with a temperature of -40 ℃ for the first 30 seconds followed by no pre-cooling are the most suitable temperature control strategies for the 70 MPa type Ⅳ hydrogen storage tank of this structure. © 2024 Science Press.
