Embodiment 1

[0032] This embodiment provides a main drive architecture of a hydrogen fuel cell, such as figure 1 As shown, the main drive architecture of the hydrogen fuel cell should include an accelerator pedal module, an air supply control module, a fuel cell system, an electric drive module and a hydrogen storage module, and the accelerator pedal module is connected to the air supply control module for signals.

[0033] Specifically, the fuel cell system includes a battery control module, a battery stack module, a battery gas supply module, a battery hydrogen supply module, and an auxiliary secondary battery module. The battery control module is respectively connected to the accelerator pedal module and the hydrogen storage module for signals; the battery stack The module is electrically connected to the electric drive module; the battery gas supply module is connected to the signal of the gas supply control module, and connected to the battery stack module through the pipeline; the bat...

Embodiment 2

[0044] The response control method of the hydrogen fuel cell in this embodiment is used to control the main driving structure of the hydrogen fuel cell in the first embodiment.

[0045] Such as figure 1 As shown, the response control method of the hydrogen fuel cell is: when the driver steps on the accelerator pedal (that is, the stroke of the accelerator pedal is greater than zero), the displacement of the accelerator pedal generates a displacement signal through the accelerator pedal control component and transmits it to the air supply control module, The accelerator pedal module triggers the air supply control module, and the air supply control module sends the air supply signal of the maximum power air demand of the battery stack module to the battery air supply module according to a predetermined strategy, so that the battery air supply module supplies the battery stack The module supplies gas. At the same time, the accelerator pedal module sends a power demand signal to ...

Embodiment 3

[0051] In this embodiment, the main drive framework of the hydrogen fuel cell in Embodiment 1 is installed on a hydrogen fuel cell light commercial vehicle with a load of 7.5 tons, and the response control method of the hydrogen fuel cell in Embodiment 2 is used to control the hydrogen fuel cell. run to enable full power operation of the hydrogen fuel cell.

[0052] Specifically, the loaded rated power of the hydrogen fuel cell system of the hydrogen fuel cell is 80kW, and the specification of its secondary battery module is 100AH*120V. The hydrogen storage module is loaded with 6 hydrogen bottles, and a hydrogenation can carry 37kg of hydrogen. The electric drive module of this light commercial vehicle has a motor power of 120kW.

[0053] When the whole vehicle is started, when the driver gives a power demand signal through the accelerator pedal, and the pedal stroke is greater than zero, the air supply control module will calculate the maximum air demand (excess coefficient...

Abstract

The invention belongs to the technical field of fuel cells, and discloses a main driving framework of a hydrogen fuel cell and a response control method of the main driving framework, an auxiliary secondary battery module is integrated in the hydrogen fuel cell, the auxiliary secondary battery module does not provide electric energy for an electric driving module, so that the hydrogen fuel cell directly provides electric energy for the electric driving module; the power source structure is simplified, the vehicle weight is reduced, the vehicle body space is saved, the working efficiency of the motor vehicle is improved, and the cost is reduced; the air supply amount of the battery air supply module is directly controlled by adopting an air supply control module, so that air and hydrogen can quickly react in a battery stack module, the quick response of the power of the hydrogen fuel cell is realized, and the full-power operation of the hydrogen fuel cell on a motor vehicle is realized; according to the response control method of the hydrogen fuel cell, the hydrogen fuel cell can realize quick response, so that the hydrogen fuel cell can realize full-power operation on a motor vehicle.

Description

technical field [0001] The invention relates to the technical field of fuel cells, in particular to a main drive architecture of a hydrogen fuel cell and a response control method thereof. Background technique [0002] It is an inevitable trend for the development of the driving source of motor vehicles to change from traditional energy to new energy. Compared with traditional internal combustion engines, hydrogen fuel cells are more efficient, up to 68%, and the overall cleanliness of energy is higher than that of secondary energy storage batteries. Hydrogen has a wide range of sources, and green hydrogen resources are abundant. The speed of hydrogenation is similar to that of gasoline refueling. The driving range of one refill is 400-700 kilometers, and the operating life is long, up to 50,000 hours (equivalent to 4 million kilometers). The overall performance is very suitable as The use of vehicle power sources is the most promising new energy power product to replace tra...
