Hydrogen refueling station control method and device, and hydrogen refueling station

Abstract

The embodiment of the invention provides a hydrogen refueling station control method, and belongs to the field of a hydrogen refueling station. The method comprises the following steps that ambient temperature is detected; and a maximum hydrogen refueling rate of the hydrogen refueling station is controlled according to the ambient temperature, wherein the lower the ambient temperature is, the greater the maximum hydrogen refueling rate is. According to the hydrogen refueling station control method and device and the hydrogen refueling station, the hydrogen refueling capacity can be maximizedunder the condition that the hydrogen refueling safety is guaranteed.

Description

technical field [0001] The invention relates to a hydrogen refueling station, in particular to a method and device for controlling a hydrogen refueling station and a hydrogen refueling station. Background technique [0002] Hydrogen energy is internationally recognized as the future green energy due to its advantages of high energy efficiency, wide source, renewable, and zero pollution of combustion products. In recent years, many countries and regions, including the United States, Japan, China, South Korea, and the European Union, are vigorously developing hydrogen vehicles and actively building hydrogen refueling stations and related hydrogen energy infrastructure. Using hydrogen as power has become an important application direction in the field of new energy. Hydrogen is used to refuel fuel cell vehicles through hydrogen refueling machines at hydrogen refueling stations, and is stored in high-pressure hydrogen cylinders on-board. [0003] The high-pressure hydrogen exp...

Problems solved by technology

Due to the fast filling speed, the vehicle-mounted hydrogen storage bottle cannot dissipate heat in time, so the temperature inside the hydrogen storage bottle rises rapidly, which may exceed the current international standard of 85°C, bringing great safety hazards

For this, there are the following countermeasures in the prior art, for example, adding a filling rate control program, by measuring the temperature in the vehicle-mounted hydrogen storage container, if the temperature exceeds the limit, stop filling immediately, and continue filling when the temperature drops back to the feasible range , but the natural cooling of the actual on-board hydrogen storage container is very slow, so not only the actual filling time is longer and the efficiency is lower, but also the method does not optimize energy consumption; or, directly set a lower filling rate to ensure the on-board storage The temperature in the hydrogen container does not exceed the limit, but the filling time is still very long and the efficiency is low
