Description

Technical Field

[0001] The utility model relates to the field of hydrogen energy trucks, in particular to a new hydrogen storage chassis structure of a hydrogen fuel cell heavy truck. Background Art

[0002] In the past two years, with the continuous increase in greenhouse gas emissions and the continuous evolution of the greenhouse effect, carbon peak and carbon neutrality in the next few years have become key issues of widespread global concern. Hydrogen energy, as a renewable secondary energy source, has gradually played an important role in life. In particular, hydrogen fuel cells are fully utilized for their key features such as high energy conversion efficiency and environmental friendliness. In the field of automotive applications, fuel cells will replace traditional fossil energy and use the process of converting chemical energy in hydrogen and oxygen into electrical energy to generate electricity to provide vehicles with a steady stream of power. Because hydrogen is not restricted by the Carnot cycle during the chemical energy conversion process, the energy utilization rate of the entire energy conversion link is higher than that of conventional energy power systems, so it has received widespread attention and research at home and abroad.

[0003] Based on this, the development of on-board application technology of hydrogen fuel cells is gradually moving towards technological maturity. On-board fuel cell technology has made continuous technological breakthroughs, and conventional models have met the power and endurance requirements of vehicles. However, in the field of commercial vehicles, especially in the application field of high-power heavy-duty traction and transportation trucks, due to the limitations of the hydrogen storage system, it is difficult for vehicles to achieve long endurance. In conventional methods, there are multiple technical paths to achieve increased vehicle endurance, but to a large extent they rely on point-to-point operation and improving mid-trip refueling. Another way is to increase the number of hydrogen storage bottles under the condition that the hydrogen storage pressure remains unchanged, thereby improving the overall endurance. Due to the limitations of cost and other factors, the current hydrogen storage cost accounts for a high cost of the entire vehicle hydrogen system, and the hydrogen storage space also seriously affects the carrying space and storage space of the entire vehicle.
