Therefore, it is urgent to develop an efficient, stable, and reliable fuel cell power supply system for hydrogen-powered two-wheelers. Utility Model Content

Detailed Implementation

[0031] To better understand the above-mentioned objectives, features, and advantages of this utility model, the solution of this utility model will be further described below. It should be noted that, unless otherwise specified, the embodiments of this utility model and the features thereof can be combined with each other.

[0032] Many specific details are set forth in the following description in order to provide a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of the present invention, and not all embodiments.

[0033] The fuel cell power supply system for hydrogen-powered two-wheeled vehicles provided in this embodiment of the invention ensures that the power supply system always provides stable and reliable power to the load, greatly enhancing the stability of the two-wheeled vehicle during operation and reducing malfunctions and safety hazards caused by voltage instability.

[0034] The following description, in conjunction with the accompanying drawings, provides an exemplary description of the fuel cell power supply system for hydrogen-powered two-wheeled vehicles and the two-wheeled vehicle provided in this utility model embodiment.

[0035] Figure 1 This is a schematic diagram of a fuel cell power supply system for a hydrogen-powered two-wheeled vehicle, provided as an embodiment of the present invention. Figure 1 As shown, the fuel cell power supply system for hydrogen-powered two-wheeled vehicles includes: a hydrogen tank 10, a fuel cell assembly 11, an energy storage device 12, and a control device 13; the fuel cell assembly 11 includes a battery stack 111, and the output end of the hydrogen tank 10 is connected to the air inlet A1 of the battery stack 111 via an air inlet pipe 14; an exhaust pipe 15 is provided at the exhaust end A2 of the battery stack 111; the control device 13 includes a control module 131, a voltage detection module 132, and a power supply module 133; the power output end A3 of the battery stack 111 is connected to the input end C1 of the power supply module 133; the energy storage device 12 includes... The first output terminal B1 is connected to the input terminal C1 of the power supply module 133, and the output terminal C2 of the power supply module 133 is connected to the load 20. The voltage detection module 132 is connected to the power output terminal A3 of the battery stack 111. A switching element 16 is provided between the energy storage device 12 and the power supply module 133. The voltage detection module 132 is connected to the control module 131, and the control module 131 is also connected to the control terminal of the switching element 16. When the output voltage of the power output terminal A3 of the battery stack 111 is less than the preset voltage, the control module 131 outputs a switch closing signal to the switching element 16.

[0036] Specifically, the fuel cell assembly 11 includes a battery stack 111; the control device 13 includes a control module 131, a voltage detection module 132, and a power supply module 133. The output end of the hydrogen tank 10 is connected to the inlet end A1 of the battery stack 111 via an inlet pipe 14, providing hydrogen to the battery stack 111; an exhaust pipe 15 is provided at the exhaust end A2 of the battery stack 111 to discharge the gases produced after the reaction. Specifically, the working principle of the battery stack 111 is as follows: hydrogen (anode) reacts electrochemically with oxygen in the air (cathode) to generate direct current electrical energy and water / heat.

[0037] The power output terminal A3 of the battery stack 111 and the first output terminal B1 of the energy storage device 12 (e.g., a battery) are both connected to the input terminal C1 of the power supply module 133; the output terminal C2 of the power supply module 133 is connected to the load 20 and is responsible for supplying power to the load 20. Specifically, a voltage detection module 132 is connected to the power output terminal A3 of the battery stack 111 to detect the output voltage of the battery stack 111. When the output voltage of the power output terminal A3 of the battery stack 111 is less than a preset voltage, the control module 131 outputs a switch closing signal to the switching element 16, allowing the energy storage device 12 to connect to the power supply module 133 through the switching element 16 to assist the fuel cell assembly 11 in supplying power, thereby ensuring a stable power supply to the load 20.

[0038] Therefore, this embodiment of the invention, by setting up a fuel cell assembly (hydrogen power generation) and an energy storage device in conjunction with a voltage detection module and a control module, allows the fuel cell stack to prioritize powering the load when its output voltage meets the load requirements. Conversely, when the output voltage is lower than a preset voltage (i.e., insufficient output power), the control module promptly outputs a switch closing signal to the switching element, enabling the energy storage device to connect to the power supply module and work together with the fuel cell stack to power the load. This flexible power supply method avoids energy waste, fully utilizes the potential of the fuel cell and energy storage device, effectively improves the energy efficiency of the entire power supply system, and extends the driving range of the two-wheeled vehicle. The voltage detection module monitors the voltage at the fuel cell stack's output terminal in real time and transmits the detected data to the control module. Based on preset voltage thresholds and real-time detection data, the control module accurately judges the output status of the battery stack and reacts quickly. By controlling the on and off of switching elements, it adjusts the power supply mode and can promptly respond to fluctuations in the output voltage of the battery stack. This ensures that the power supply system always provides stable and reliable power to the load, greatly enhancing the stability of the two-wheeled vehicle during operation and reducing malfunctions and safety hazards caused by voltage instability.

[0039] Furthermore, due to the clean and pollution-free nature of hydrogen energy, this power supply system uses hydrogen as fuel and produces no pollutants or greenhouse gas emissions during operation, making it environmentally friendly. Compared to traditional fuel-powered two-wheeled vehicles, it effectively reduces exhaust emissions that pollute urban air quality, making a positive contribution to improving the urban ecological environment.

[0040] In some embodiments, such as Figure 1 As shown, a first solenoid valve 17 is provided on the intake pipe 14, and a second solenoid valve 18 is provided on the exhaust pipe 15; the opening ends of the first solenoid valve 17 and the second solenoid valve 18 are both communicatively connected to the control module 131.

[0041] Specifically, the control module 131 can regulate the supply of hydrogen from the hydrogen tank 1 to the battery stack 111 by controlling the opening and closing of the first solenoid valve 17; at the same time, it can regulate the exhaust of the battery stack 111 by controlling the opening and closing of the second solenoid valve 18.

[0042] In this way, precise control of the reaction gas path in the fuel cell assembly 11 can be achieved. For example, when the system starts or stops, the supply of hydrogen and the emission of exhaust gas can be precisely controlled, ensuring the safe and efficient operation of the fuel cell assembly 11.

[0043] In some embodiments, continue as follows Figure 1 As shown, the fuel cell power supply system for hydrogen-powered two-wheeled vehicles also includes:

[0044] Pressure sensor 19 is installed on the air intake pipe 14 and is located between the hydrogen tank 10 and the first solenoid valve 17.

[0045] The pressure sensor 19 is installed on the intake pipe 14 and located between the hydrogen tank 10 and the first solenoid valve 17. It can detect the pressure of hydrogen in the intake pipe 14 in real time and provide the control module 131 with the pressure data of hydrogen supply. This allows the control module 131 to accurately adjust the amount of hydrogen supplied according to the pressure, in conjunction with the first solenoid valve 17, to ensure that the hydrogen supply pressure of the battery stack 111 is stable within a suitable range, thus ensuring the reaction efficiency and safety of the battery stack.

[0046] In some embodiments, such as Figure 1 As shown, the energy storage device 12 also includes a second output terminal B2, which is connected to the power supply terminal of the control module 131.

[0047] Specifically, the second output terminal B2 of the energy storage device 12 is connected to the power supply terminal of the control module 131, which can provide power to the control module 131 and ensure that the control module 131 can work continuously and stably.

[0048] In some embodiments, such as Figure 1 As shown, the switching element 16 is a transistor switch.

[0049] Specifically, transistor switches are characterized by fast response speed, high control precision, and low power consumption. In this embodiment, the switching element 16 is set as a transistor switch. When the control module 131 outputs a switch closing signal, the transistor switch can quickly turn on, allowing the electrical energy of the energy storage device 12 to be connected to the input terminal C1 of the power supply module 133 through the second output terminal B1; conversely, it can also quickly turn off.

[0050] In some embodiments, the switching element 16 may be configured as other switches known to those skilled in the art, without specific limitations.

[0051] In some embodiments, such as Figure 1 As shown, the fuel cell assembly 11 also includes a temperature sensor 112, which is disposed on the fuel cell stack 111 and is communicatively connected to the control module 131.

[0052] Specifically, a temperature sensor 112 is installed on the battery stack 111 to monitor the operating temperature of the battery stack 111 in real time. The temperature sensor 112 transmits the monitored temperature to the control module 131, which can accurately grasp the thermal state of the battery stack 111.

[0053] Because the chemical reaction efficiency and safety of the fuel cell stack 111 are sensitive to temperature and must be maintained within a suitable range, excessively high or low temperatures can affect performance and even pose safety risks. The control module 131 can adjust other components in conjunction with temperature data. For example, when the temperature is too high, it can adjust the hydrogen supply of the first solenoid valve 17, optimize the reaction intensity, or cooperate with the heat dissipation system (such as controlling the fan operation) to cool down the fuel cell assembly 11. When the temperature is too low, it can control the heating system to raise the temperature, thereby ensuring the efficient and safe operation of the fuel cell assembly 11.

[0054] In some embodiments, such as Figure 1 As shown, the fuel cell assembly 11 also includes a fan 113, which is disposed on one side of the fuel cell stack 111; the open end of the fan 113 is communicatively connected to the control module 131.

[0055] Specifically, a fan 113 is positioned on one side of the battery stack 111, and its open end is communicatively connected to the control module 131. By controlling the operation of the fan 113, heat can be dissipated from the battery stack 111, ensuring that the battery stack 111 operates within a suitable temperature range.

[0056] Specifically, in conjunction with the aforementioned embodiments, the fan 113 works in conjunction with the temperature sensor 112, and the control module 131 controls the start / stop and speed of the fan 113 based on the temperature data transmitted from the temperature sensor 112. For example, when the temperature of the battery stack 111 exceeds a preset suitable value, the control module 131 sends a start signal to the fan 113, causing the fan to operate and accelerate airflow to quickly remove the heat generated by the battery stack. Once the temperature drops to a safe range, the control module 131 can control the fan to slow down or stop, preventing excessive heat dissipation and energy waste.

[0057] Therefore, the above heat dissipation design can prevent the battery stack from aging or being damaged due to excessive temperature, or from causing safety risks due to thermal runaway, while ensuring the stability of the chemical reaction efficiency of the stack, indirectly improving the reliability and endurance of the entire power supply system.

[0058] In some embodiments, such as Figure 1 As shown, the control module 131 is an FCU controller.

[0059] Specifically, the control module 131 is an FCU controller. The fuel cell controller (FCU) is the core control hub of the entire hydrogen-powered two-wheeled vehicle power supply system. The FCU controller is a dedicated controller designed specifically for fuel cell systems, which can accurately adapt to the working characteristics of fuel cells and coordinate the control requirements of various sensor signals and actuators.

[0060] Based on the above embodiments, this utility model also provides a two-wheeled vehicle, including a fuel cell power supply system for hydrogen energy two-wheeled vehicles as described in the above embodiments. Therefore, all of them have the same or similar beneficial effects, which will not be elaborated here.

[0061] In some embodiments, Figure 2 This is a structural schematic diagram of a two-wheeled vehicle provided for an embodiment of the present utility model. (In conjunction with...) Figure 1 and Figure 2 The two-wheeled vehicle also includes a human-machine interaction device 21, which is communicatively connected to the control module 131.

[0062] Specifically, the human-machine interface device 21 is communicatively connected to the control module 131, thereby establishing an information exchange bridge between the user and the fuel cell power supply system for hydrogen-powered two-wheeled vehicles.

[0063] For example, the human-machine interface device is an operable display screen integrated into the vehicle control panel. The control module 131 transmits key data (such as data detected by the pressure sensor and the temperature sensor) to the display screen, allowing the user to monitor the system's operating status in real time. Additionally, the user can send operation commands through the display screen, such as starting or stopping the power supply system or setting the system's operating mode.
