Hydrogenation control device and method

Abstract

The invention provides a hydrogenation control device and method, and belongs to the technical field of hydrogenation. The hydrogenation control method comprises the steps of obtaining the initial parameters of a vehicle-mounted hydrogen storage device, wherein the initial parameters comprise the volume of the vehicle-mounted hydrogen storage device, initial hydrogen pressure and initial environment temperature; according to the initial parameters, calculating the filling rate and target pressure of hydrogenation, wherein the calculated filling rate and target pressure enable the hydrogen temperature in the hydrogenation pressure to be in a preset safety range; and controlling a hydrogenation station to hydrogenate the vehicle-mounted hydrogen storage device to the calculated target pressure at the calculated filling rate. The hydrogenation control device and method do not need the real-time communication between the hydrogenation station and a vehicle, and controls the filling processby obtaining the filling rate and the target pressure through the initial parameters of the vehicle-mounted hydrogen storage device measured by the hydrogenation station. The process is simple and easy to implement, and the reliability of hydrogenation process is ensured.

Description

technical field [0001] The invention relates to the technical field of hydrogenation, in particular to a hydrogenation control device and method. Background technique [0002] Hydrogen energy is considered to be one of the most promising secondary energy sources due to its outstanding advantages such as diverse sources, clean environmental protection, and large-scale storage and transportation. Hydrogen fuel cell vehicles are one of the important application terminals of hydrogen energy. Many auto giants in the world have launched mass-produced hydrogen fuel cell vehicles around 2015. At present, the research on hydrogen fuel cell vehicles is multifaceted, but the filling control strategy of the hydrogenation station to the on-board hydrogen storage (hereinafter referred to as the hydrogenation control strategy) is undoubtedly one of the focuses of research at home and abroad. [0003] One of the technical problems that the existing hydrogen refueling control strategy mainl...

Problems solved by technology

But in reality, because the same vehicle will be refueled at different types of hydrogen refueling stations, and the same hydrogen refueling station will also provide hydrogen refueling services to different types of vehicles, and different types of vehicles or hydrogen refueling stations often have different communication standard, making it difficult to communicate between the vehicle and the hydrogen refueling station

Accordingly, for the situation where the vehicle and the hydrogen refueling station cannot communicate, it is also difficult to realize the solution in the prior art to control the hydrogen refueling rate to adjust the hydrogen temperature based on the real-time feedback temperature or pressure of the on-board hydrogen storage device.
