[0031] (Embodiment 1)

[0032] See Figure 1 , the hydrogen energy assisted vehicle of this embodiment includes a central control system 1, a hydrogen fuel cell system 2, a power control system 3, and a lithium battery pack 4.

[0033] The central control system 1 controls the operation of the hydrogen fuel cell system 2 and the power control system 3 and receives the feedback information from the hydrogen fuel cell system 2 and the power control system 3. The central control system includes a central control module 1-1, as well as a rear wheel lock 1-2, a hydrogen storage tank compartment lock 1-3, and front and rear lights 1-4 that are electrically connected to the central control module 1-1. The central control module 1-1 is electrically connected to the hydrogen fuel cell system 2 and the power control system 3.

[0034] The hydrogen fuel cell system 2 generates electrical energy to supply power to the central control system 1, the power control system 3, and the lithium battery pack 4. The hydrogen fuel cell system 2 includes a hydrogen storage tank 2-1, an intake solenoid valve 2-2, a hydrogen fuel cell stack 2-3, and an exhaust solenoid valve 2-4 that are sequentially connected by pipelines. A pressure transmitter 2-6 is provided on the pipeline between the intake solenoid valve 2-2 and the hydrogen fuel cell stack 2-3. A temperature sensor 2-7 is provided on the hydrogen fuel cell stack 2-3. A heating module 2-8 is provided outside the hydrogen storage tank 2-1. And a hydrogen fuel cell management module 2-5 that is electrically connected to the intake solenoid valve 2-2, the hydrogen fuel cell stack 2-3, the exhaust solenoid valve 2-4, the pressure transmitter 2-6, the temperature sensor 2-7, and the heating module 2-8. The hydrogen fuel cell management module 2-5 is electrically connected to the central control system 1, the power control system 3, and the lithium battery pack 4. The main function of the hydrogen fuel cell management module 2-5 is to collect information from the pressure transmitter 2-6 and the temperature sensor 2-7, and control the intake solenoid valve 2-2, the hydrogen fuel cell stack 2-3, the exhaust solenoid valve 2-4, and the heating module 2-8 to work.

[0035] The power control system 3 controls the driving speed, and the lithium battery pack 4 supplies power to the central control system 1 and the power control system 3. The power control system 3 includes a motor controller 3-1, and left and right brake handles 3-2, a boost sensor 3-3, and a drive motor 3-4 that are electrically connected to the motor controller 3-1. The motor controller 3-1 is electrically connected to the central control system 1, the hydrogen fuel cell system 2, and the lithium battery pack 4. The main function of the motor controller 3-1 is to receive signals from the left and right brake handles 3-2 and the boost sensor 3-3 and drive the drive motor 3-4 to rotate, and control the rotation speed of the drive motor 3-4.

[0036] The working principle of the hydrogen energy assisted vehicle in this embodiment is:

[0037] When a user rents a vehicle, the central control module 1-1 will open the rear wheel lock 1-2 and the front and rear lights 1-4, and send a startup command to the hydrogen fuel cell management module 2-5 and the motor controller 3-1. The hydrogen fuel cell management module 2-5 starts the hydrogen fuel cell stack 2-3. When the hydrogen fuel cell management module 2-5 receives the startup command, the hydrogen fuel cell management module 2-5 will first detect the pressure of the hydrogen storage tank 2-1 through the pressure transmitter 2-6, and detect the temperature of the hydrogen fuel cell stack 2-3 through the temperature sensor 2-7. If the detected pressure or temperature does not meet the requirements, the hydrogen fuel cell stack 2-3 will not be started, and at the same time, fault information will be uploaded to the central control module 1-1. If the requirements are met, the hydrogen fuel cell stack 2-3 will be started, and the intake solenoid valve 2-2 and the heating module 2-8 will be opened. During operation, the hydrogen fuel cell management module 2-5 will adjust the fan speed of the hydrogen fuel cell stack 2-3 and the exhaust frequency of the exhaust solenoid valve 2-4 according to the temperature sensor 2-7 and the output power of the hydrogen fuel cell stack 2-3.

[0038] When the user returns the vehicle, the central control module 1-1 will turn off the rear wheel lock 1-2 and the front and rear lights 1-4, and send a shutdown command to the hydrogen fuel cell management module 2-5 and the motor controller 3-1. The hydrogen fuel cell management module 2-5 will detect the remaining power of the lithium battery pack 4. If the remaining power of the lithium battery pack 4 is greater than the predetermined value, the hydrogen fuel cell stack 2-3 will be turned off. If the remaining power of the lithium battery pack 4 is less than the predetermined value, the hydrogen fuel cell stack 2-3 will continue to work to charge the lithium battery pack 4 until it is fully charged. Then, the hydrogen fuel cell stack 2-3 and its own power supply will be turned off.

[0039] When in the rental waiting state, the central control module 1-1 will wake up the hydrogen fuel cell management module 2-5 at regular intervals and send a command to inquire about the remaining gas volume. After being woken up, the hydrogen fuel cell management module 2-5 will detect the remaining power of the lithium battery pack 4. If the remaining power of the lithium battery pack 4 is greater than the predetermined value, the hydrogen fuel cell stack 2-3 will be turned off. If the remaining power of the lithium battery pack 4 is less than the predetermined value, the hydrogen fuel cell stack 2-3 will continue to work to charge the lithium battery pack 4 until it is fully charged. Then, the hydrogen fuel cell stack 2-3 and its own power supply will be turned off. This working mode not only reduces the standby power consumption but also ensures that the lithium battery pack 4 has sufficient power when the user rents the vehicle next time.

[0040] When the hydrogen in the hydrogen storage tank 2-1 is lower than the predetermined value, the central control system will notify the maintenance personnel to replace the hydrogen storage tank 2-1 through the background, that is, the central control module 1-1 will send the information that the hydrogen storage tank 2-1 needs to be replaced to the background. After receiving the information, the background will send the information of replacing the hydrogen storage tank 2-1 to the mobile phone of the maintenance personnel near the hydrogen storage tank 2-1. Then, the maintenance personnel will send a command to open the hydrogen storage tank compartment lock 1-3 to the central control module 1-1 through the mobile phone. After receiving the command, the central control module 1-1 will open the hydrogen storage tank compartment lock 1-3. After replacing the hydrogen storage tank 2-1, the hydrogen storage tank compartment lock 1-3 will be closed, and at the same time, the information that the hydrogen storage tank 2-1 has been replaced will be sent to the background. After receiving it, the background will update the information of the vehicle where the hydrogen storage tank 2-1 is located and refresh the information of the vehicle's cruising range.

[0041] The specific embodiments described above have further elaborated on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
