AI Technical Summary

Problems solved by technology

Since the air compressor usually rotates at high speed, if the air compressor speed is adjusted frequently, it is easy to cause damage to the air compressor
If the air compressor is not adjusted, it will cause the air compressor to always rotate with a large load, resulting in energy waste

Embodiment Construction

[0040] The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0041] Please refer to figure 1 , the present invention proposes a hybrid energy storage system for fuel cell vehicles, including a fuel cell 1, an air compressor 2, a storage battery 3, a pressure storage tank 4 and a braking energy recovery device 5; wherein, the braking energy recovery device 5 is consistent with the braking energy recovery device 5 on existing electric vehicles and fuel vehicles, and can be realized by those skilled in the art. I won't repeat them here.

[0042] The air compressor 2 is connected to the fuel cell 1 , and the air compressor 2 is used to provide high-pressure air to the fuel cell 1 . This is the same as the existing structure. Specifically, the air compressor 2 communicates with the air inlet of the fuel cell 1 through a network pipe.

The invention can reduce energy waste.

Description

technical field [0001] The invention relates to the technical field of fuel cell vehicles, in particular to a hybrid energy storage system for fuel cell vehicles. Background technique [0002] The hydrogen-oxygen fuel cell vehicle is the vehicle with the cleanest emission in the existing technology, and it has already begun to be applied in practice. [0003] In hydrogen-oxygen fuel cell vehicles, since the amount of power generation can be controlled by the amount of oxygen, the amount of air can be appropriately larger than the required amount. Since the air compressor usually rotates at a high speed, if the air compressor speed is adjusted frequently, it is easy to cause damage to the air compressor. If the air compressor is not adjusted, it will cause the air compressor to always rotate with a large load, resulting in waste of energy. [0004] Therefore, how to make full use of the energy of the fuel cell vehicle is one of the important problems to be solved urgently b...
