[0027] Figure 1 A schematic diagram of the system architecture applying the technical solution of this application is shown.

[0028] like Figure 1 As shown, the power supply system may include a power supply device 110, a device to be charged 120, and an external power grid 130. The power supply device 110 includes a hydrogen storage module 111 and a power generation module 112. The hydrogen storage module 111 is used to store hydrogen and may include components for storing hydrogen such as carbon fiber fully wound hydrogen storage cylinders, vertical / horizontal metal-lined hydrogen storage tanks, and porous carbon material hydrogen storage containers. The power generation module 112 is used to convert the hydrogen provided by the hydrogen storage module into electrical energy and includes a first battery module, a second battery module, and an electronic control module. The electronic control module is used to control the first and second battery modules to provide power to the device to be charged, and to control the first battery module to supply power to the external power grid.

[0029] In an embodiment of the present application, the first battery module is an energy conversion assembly that converts hydrogen gas supplied by the hydrogen storage module 111 into electrical energy, and can include a fuel cell stack, a hydrogen circulation pump, a gas-water separation device, a two-stage supercharged air compressor, a intercooler, etc. The power supply principle is that hydrogen gas separates electrons and protons through a catalyst at the anode, the protons pass through the proton exchange membrane to the cathode, and the electrons form an electric current through the wire; at the same time, the hydrogen circulation pump improves the utilization rate of hydrogen, the two-stage supercharged air compressor provides compressed air that meets the purity (such as GB / 3095-2012 standard), and finally realizes stable conversion of hydrogen energy to electrical energy. Among them, the fuel cell stack can be a proton exchange membrane fuel cell, an alkaline fuel cell, a phosphoric acid fuel cell, a molten carbonate fuel cell, etc., which are not limited by the present application.

[0030] The second battery module can include an energy storage battery, a battery management system, an energy storage converter, and a battery cooling fan / water cooling plate, which is used to provide initial power for auxiliary equipment (air compressor, hydrogen circulation pump, water pump) when the system starts, and to provide power for the charging equipment alone when the first battery module is not started. Among them, the energy storage battery can be a lithium iron phosphate battery, a ternary lithium battery, a vanadium flow battery, a super capacitor, etc., which are not limited by the present application.

[0031] The electric control module includes various components for collecting data and controlling the operation of the power generation module, such as a fuel cell control unit (FCU), a current sensor, a temperature sensor. Optionally, the electric control module can be used to collect the state of charge (SOC) of the second battery module and the operating parameters (such as power, temperature) of the first battery module, and determine the system power supply mode according to the SOC of the second battery module. Moreover, the electric control module can also be connected to an external energy supervision platform through a data interface, for receiving control instructions issued by the external energy supervision platform. The external energy supervision platform includes an external energy monitoring and dispatching system with data collection, analysis, remote control and operation and maintenance management functions. The control instructions include instructions for controlling the hydrogen-electric coupling system one-key start-stop. In addition, the control process of the electric control module and the collected data can be displayed externally through a touch screen.

[0032] Optionally, the power supply equipment 110 and the charging equipment 120 are connected through a power connection line that adapts to the power consumption standard of the charging equipment. Among them, the charging equipment 120 can be an electric vehicle, an electric engineering machinery, an industrial park production equipment, a small compressor, a household appliance and a communication base station, etc. The power supply equipment 110 and the external power grid 130 are connected through a power connection line that adapts to the power consumption standard of the external power grid, wherein the external power grid 130 can be a national power grid, a municipal power grid, a micro power grid, and a charging station dedicated power grid, etc.

[0033] The technical scheme provided by the embodiments of the present application can be applied to the power supply device 110.

[0034] The control method of the hydrogen-electricity coupling system provided by the present application will be described in detail in combination with the specific embodiments.

[0035] Figure 2 A flowchart to which the technical scheme of the present application is applied is schematically shown. As shown in the figure, Figure 2 The control method of the hydrogen-electricity coupling system provided by the present application includes steps 210 to 230, and specifically as follows. Step 210, acquiring the power supply parameter of the external power grid.

[0036] Specifically, the power supply parameter of the external power grid is a core electrical characteristic index representing the power quality, operation stability and power supply capacity when the external power grid transmits power to associated devices (such as the hydrogen-electricity coupling system, the device to be charged, the industrial load, etc.), which can include voltage, current, output frequency, reactive power and active power. The reactive power refers to the power in the external power grid for establishing and maintaining the magnetic field of the electrical equipment (such as the motor, the transformer), which does not directly do work but determines the stability level of the grid voltage (insufficient reactive power will cause voltage drop, and excessive reactive power will cause voltage rise). The active power refers to the power in the external power grid actually used to drive the electrical equipment to do work (such as motor rotation, equipment heating), which is a core index for measuring the "effective power supply capacity" of the grid and directly determines how much actual demand of the load the grid can meet.

[0037] In an embodiment of the present application, the process of acquiring the power supply parameter of the external power grid can be: first, according to the control response requirement of the hydrogen-electricity system (such as the sampling frequency ≥ 50 Hz, i.e. collecting once every 20 ms), reading the sensor signal according to the preset period to acquire the voltage and output frequency of the external power grid; then, pre-processing the acquired voltage and output frequency; then, performing validity verification on the pre-processed parameters; finally, outputting the external power grid parameters that pass the verification.

[0038] Optionally, the pre-processing can include using sliding average filtering (taking the average of 5-10 consecutive sampling values) or Kalman filtering to eliminate transient pulse interference (such as voltage glitches caused by motor starting), and using a first-order low-pass filtering method to smooth the frequency signal to avoid frequency jump misjudgment caused by high-frequency noise.

[0039] The validity check can include: range check, checking whether the parameters are within a physically reasonable range (such as the low-voltage power grid voltage cannot exceed 450V, the frequency cannot be lower than 45Hz or higher than 55Hz), and the values outside the range are marked as "invalid values"; mutation check, if the difference between the parameters collected at adjacent two times exceeds a threshold (such as voltage mutation ±10%, frequency mutation ±0.5Hz), it is determined as "suspicious value", triggering secondary collection (re-collection once for verification); consistency check, logical verification is performed on the associated parameters (such as the phase relationship of voltage and current) (such as three-phase voltage unbalance degree less than or equal to 2%), and the inconsistency is marked as "abnormal data", wherein if the continuous three times of collection are invalid / abnormal data, a "collection failure prompt" is triggered.

[0040] Step 220, determining a control mode of the hydrogen-electric coupling system according to the power supply parameters.

[0041] Specifically, the control mode includes any one of a first control mode and a second control mode; wherein the first control mode is used to provide power for the external power grid and the device to be charged, and the second control mode is used to provide power for the device to be charged.

[0042] In an embodiment of the present application, the process of determining the control mode includes: if the voltage and output frequency of the external power grid are within a preset interval, determining the control mode as any one of the first control mode and the second control mode; if the voltage and output frequency of the external power grid are not within the preset interval, determining the control mode as the second control mode.

[0043] Specifically, the preset interval is a numerical range set in advance in the control unit based on the external power grid operation standard, the device safety threshold and the system power supply target, which is used to judge whether the external power supply parameters (such as voltage and output frequency) are normal.

[0044] In an embodiment of the present application, the preset interval can be that the voltage is within the interval of 187-253V and the output frequency is within the interval of 49.5-50.5Hz. When the voltage is within the interval of 187-253V, it can be compatible with problems such as "grid transient fluctuation" and "end power distribution loss". For example, when the distribution line of a residential area is long, the end voltage can be 5%-8% lower than the outlet voltage of the transformer substation; the start of the charging pile can cause transient voltage drop, and this interval can avoid misjudgment of grid anomaly due to "normal fluctuation". When the output frequency is within the interval of 49.5-50.5Hz, it can be compatible with short-term load fluctuations, such as sudden start of large motors in factories causing load surge, and the frequency drops to 49.5Hz for a short time.

[0045] If the obtained external power grid parameters show that they are within this preset interval, it indicates that the power grid is in a stable state, and at this time, the hydrogen electricity in the hydrogen electricity coupling system can not only meet the demand of the to-be-charged device, but also can feed back the redundant power to the power grid, thereby avoiding the waste of hydrogen energy and improving the utilization rate of hydrogen energy. If the obtained external power grid parameters show that they are out of this preset interval, it indicates that the power grid enters a "fault edge state" (for example, too low voltage may cause transformer to burn out, and too high frequency may cause electrical equipment to run at high speed), at this time, the to-be-charged device cannot be powered by the external power grid.

[0046] Step 230: controlling the hydrogen electricity coupling system to supply power according to the determined control mode.

[0047] Specifically, if the control mode is the first control mode, the first battery module is used to supply power to the external power grid and the to-be-charged device. The first battery module is used to convert hydrogen into electrical energy to realize power supply.

[0048] In an embodiment of the present application, the process of using the first battery module to supply power to the external power grid and the to-be-charged device can be: first, obtaining the power generation power of the first battery module and the power consumption power of the to-be-charged device; if the power generation power of the first battery module is less than or equal to the power consumption power of the to-be-charged device, controlling the first battery module to supply power to the to-be-charged device according to the power generation power; if the power generation power of the first battery module is greater than the power consumption power of the to-be-charged device, controlling the first battery module to supply power to the to-be-charged device according to the power consumption power, and controlling the first battery module to supply power to the external power grid according to the difference between the power generation power and the power consumption power.

[0049] Specifically, the power generation power of the first battery module refers to the ability of the module to output electrical energy to the outside per unit time when hydrogen is used as the energy input source and the hydrogen energy is converted into electrical energy through the electrochemical reaction of the first battery module (such as a hydrogen fuel cell). The power generation power of the first battery module is positively correlated with the hydrogen supply rate (such as the hydrogen flow rate of the hydrogen storage module). Within the rated capacity range of the battery, the greater the hydrogen flow rate, the more hydrogen atoms participate in the reaction per unit time, the greater the generated current, and the higher the power generation power. Conversely, the power decreases. The power consumption power of the to-be-charged device refers to the rate at which the to-be-charged device obtains electrical energy from the system per unit time during the charging process, which dynamically changes with the type of device, the charging stage, and the load state.

[0050] In an embodiment of the present application, assuming that the power consumption of the device to be charged is 60 kW, if the power generation of the first battery module is 50 kW, which is less than the power consumption of the device to be charged, the first battery module is controlled to supply power to the device to be charged at a full power of 50 kW; if the power generation of the first battery module is 80 kW, which is greater than the power consumption of the device to be charged, the first battery module is controlled to supply power to the device to be charged at a power of 60 kW first to meet the demand of the device, and the remaining 20 kW is fed back to the external power grid.

[0051] In this way, the power supply mode is determined by comparing the power consumption of the device to be charged with the power generation of the first battery module, which can on the one hand accurately match the supply and demand of energy. If the power generation is less than or equal to the power consumption, the basic power demand of the device to be charged is prioritized to avoid interruption or efficiency reduction of the device due to insufficient power supply. If the power generation is greater than the power consumption, the excess energy can be fed back to the external power grid to maximize the utilization of energy converted from hydrogen, reduce hydrogen and electricity redundancy and waste, and at the same time provide supplemental power for the power grid to help balance the load of the power grid. On the other hand, this mode not only avoids the impact on the power grid caused by blind use of the first control mode for grid connection (such as system power imbalance caused by not connecting to the grid when the power generation is excessive), but also prevents energy from being idle due to single device power supply, which can significantly enhance the supply and demand adaptability and operational economy of the hydrogen and electricity coupling system.

[0052] In an embodiment of the present application, if the control mode is the second control mode, the power supply mode is first determined according to the state of charge of the second battery module; and then the device to be charged is provided with power according to the power supply mode.

[0053] Specifically, the second battery module is connected with the external power grid and is used to store the power transmitted by the external power grid; and the power supply mode includes at least one of using the first battery module for power supply and using the second battery module for power supply.

[0054] Optionally, if the state of charge of the second battery module is within a first charge threshold interval, the power supply mode is determined to be using the first battery module alone for power supply, so as to ensure that the second battery module reserves basic charge for system startup or emergency, while limiting pure electric output to the outside to prevent battery damage due to over-discharge. In the present application, the first charge threshold interval can be 10% < SOC < 40%.

[0055] Optionally, if the state of charge of the second battery module is within a second charge threshold interval, the power supply mode is determined to be using any one of the second battery module and the first battery module for power supply. In the present application, the second charge threshold interval can be 40% < SOC < 95%.

[0056] Optionally, if the state of charge of the second battery module is in a third power threshold interval, it is determined that the second battery module has sufficient power, and the power supply mode is determined to be using the second battery module alone for power supply, and the first battery module remains in a shutdown state, avoiding unnecessary hydrogen energy consumption. In the technical solution of the present application, the third power threshold interval can be SOC≥95%.

[0057] In an embodiment of the present application, if the power supply mode is using the first battery module alone for power supply, the rated power of the first battery module is used to provide power to the device to be charged, and the difference between the rated power and the power consumption of the device to be charged is used to provide power to the second battery module.

[0058] Specifically, the rated power of the first battery module refers to the maximum effective power that the first battery module can continuously output within the safe operating boundary (such as stable hydrogen supply, temperature / pressure meeting standards). From the perspective of electrochemical reaction characteristics, when the core components of the first battery module operate at rated power, the hydrogen flow, catalyst activity, and proton conduction efficiency are in an optimal matching state, which can not only avoid the decrease in conversion efficiency caused by insufficient catalyst activity when running at low power, but also prevent the risk of hydrogen evolution / thermal runaway caused by excessive hydrogen supply when running at high power.

[0059] According to the rated power of the first battery module, power is provided to the device to be charged. If the rated power of the first battery module is less than or equal to the power consumption of the device to be charged, controlling the first battery module to supply power in full cannot completely meet the peak demand of the device to be charged, but the system has locked this mode, the purpose is to prioritize power supply stability rather than peak demand, to avoid damaging the first battery module by forcibly running at high power. If the rated power of the first battery module is greater than the power consumption of the device to be charged, after controlling the first battery module to supply power to the device to be charged in full, the difference between the rated power and the power consumption of the device to be charged is used to supplement power to the second battery module. When the first battery module cannot maintain rated power due to insufficient hydrogen supply, or the power consumption of the device to be charged suddenly increases, the second battery module that has been supplemented with power can quickly cut in to supply power, avoiding interruption of device power supply, forming a dual protection of first battery module main power supply and second battery module auxiliary power supply.

[0060] Optionally, during the process of supplementing power to the second battery module, the state of charge SOC and the temperature of the second battery module can be monitored in real time. If the SOC rises to a preset upper limit (such as 90%) or the temperature exceeds 45℃, the power supplementing is immediately stopped to avoid overcharging leading to battery swelling or thermal runaway; at the same time, the maximum power supplementing current is limited (such as not exceeding the rated charging current of the second battery module) to prevent large current impact from shortening the battery life.

[0061] In an embodiment of the present application, if the power supply mode is to use the second battery module to supply power alone, the second battery module is controlled to supply power to the device to be charged until the state of charge of the second battery module reaches the preset power threshold, and the power supply is stopped.

[0062] Specifically, the preset power threshold refers to a critical state of charge value set in advance in the control unit to trigger the power supply mode switching or stop the power supply, so as to avoid damage to the battery or safety risks caused by excessive charging and discharging.

[0063] In an embodiment of the present application, if the power supply mode is to use the first battery module and the second battery module to supply power together, the second battery module is controlled to supply power to the device to be charged preferentially; if the power generation of the second battery module is less than or equal to the power consumption of the device to be charged, the first battery module is controlled to supply power to the device to be charged according to the difference between the power consumption of the device to be charged and the power generation of the second battery module.

[0064] Specifically, the power generation of the second battery module refers to the rate of delivering power to the device to be charged or the external power grid per unit time in the discharging process of the second battery module connected to the external power grid.

[0065] The use of the second battery module to supply power preferentially is on the one hand because the electrical energy stored in the second battery module has been converted into ready-to-use power, and preferential use of this power can avoid unnecessary consumption of hydrogen energy, reduce hydrogen loss of the hydrogen storage module, and reduce energy conversion cost; on the other hand, the discharging response speed of the second battery module is fast, and there is no need for a preheating process for hydrogen energy conversion, which can quickly match the instantaneous power demand of the device to be charged.

[0066] In the power supply process, the system can monitor the power generation of the second battery module and the power consumption of the device to be charged in real time through the power sensor, if the power generation of the second battery module can completely cover the demand of the device, the power supply of the second battery module alone is maintained; if the power generation of the second battery module is less than or equal to the power consumption of the device to be charged, the first battery module is immediately triggered to start power compensation: by calculating the power difference between the power generation of the second battery module and the power consumption of the device to be charged, and adjusting the hydrogen supply rate and the electrochemical reaction intensity of the first battery module, the first battery module outputs the difference power; at the same time, the output voltage of the second battery module is matched through the DC / DC converter, so as to ensure that the two-way power of the first battery module and the second battery module is cooperatively merged into the device power supply loop, thus avoiding the interruption of device charging caused by insufficient power supply of the single module, and preventing the waste of hydrogen energy caused by excessive power generation of the first battery module, and further taking into account the energy utilization efficiency and the stability of device power supply.

[0067] In the technical scheme provided in the embodiments of the present application, a control method of a hydrogen-electricity coupling system, a system, a device and a computer readable medium are provided, and the method comprises the following steps: first, obtaining power supply parameters of an external power grid; the power supply parameters at least include voltage and output frequency of the external power grid; then, determining a control mode according to the power supply parameters; the control mode includes a mode of providing power for at least one of the external power grid and a to-be-charged device; finally, providing power for the to-be-charged device according to the control mode. In this way, the power supply logic can be dynamically adjusted according to the power supply parameters of the external power grid, on the one hand, the power converted from hydrogen electricity is reasonably distributed to the external power grid and the to-be-charged device, and the hydrogen electricity resources are maximized, on the other hand, the interference of an abnormal power grid on the power supply process can be avoided, and the power supply stability is improved.

[0068] In an embodiment of the present application, the method further comprises: determining a working mode of the first battery module; and controlling the first battery module to provide power for the to-be-charged device according to a power generation power corresponding to the working mode.

[0069] Specifically, the working mode includes a first working mode and a second working mode, and the first working mode and the second working mode are different in the confirmation manner of the power generation power of the first battery module.

[0070] Optionally, the first working mode can be a manual mode, and if the working mode is the first working mode, the first battery module can be controlled to provide power for the to-be-charged device according to a preset power generation power. The preset power generation power is a power generation power value of the first battery module set by a user in advance.

[0071] Optionally, the second working mode can be an automatic mode, and if the working mode is the second working mode, the power generation power of the first battery module is first determined according to the state of charge of the second battery module; and then the first battery module is controlled to provide power for the to-be-charged device according to the determined power generation power.

[0072] In an embodiment of the present application, when the state of charge SOC of the second battery module is greater than or equal to 90%, the power of the second battery module is close to a full power state, and no additional power supply is needed. If the first battery module continues to supply power, it will cause power surplus, and increase the consumption of hydrogen energy and the loss of start-stop of the fuel cell unit, so the first battery module can be put into standby mode to stop power generation at this time, so as to prolong the service life of the fuel cell in the first battery module.

[0073] When the state of charge (SOC) of the second battery module is within the fourth charge threshold range (e.g., SOC < 65%), relying solely on the second battery module for power may lead to power outages for the device being charged due to insufficient charge (e.g., the charging station stopping operation), or damage to the battery due to over-discharge (below the critical value). In this situation, the first battery module can be allowed to supply power at full power output, quickly providing stable power to the device being charged and charging the second battery module, preventing further decrease in the SOC of the second battery module, thereby ensuring the continuity of system power supply and battery safety.

[0074] When the state of charge (SOC) of the second battery module is within the fifth threshold range (e.g., 65% < SOC < 90%), the power output of the first battery module can be dynamically adjusted based on the power consumption of the device being charged. For example, the power output can be increased when the power consumption of the device is high and decreased when the power consumption is low, so that the SOC of the second battery module is kept stable between 80% and 90% until the user manually shuts down the device. This avoids energy waste caused by the first battery module operating at full power, while continuously replenishing the power of the second battery module, ensuring that the system has redundant power to cope with fluctuations in the power consumption of the device being charged, and achieving stable operation in "unattended" mode.

[0075] When the state of charge (SOC) of the second battery module is below 10%, the second battery module is in a state of deep discharge and cannot provide starting power for the auxiliary equipment of the first battery module (such as air compressor and hydrogen circulation pump). Therefore, an external power supply is required to replenish the basic power of the second battery module to ensure that the auxiliary equipment works normally until the SOC of the second battery module is above 10% before the fuel cell can be started.

[0076] Figure 3A and Figure 3B The diagram schematically illustrates a device architecture provided in one embodiment of this application, wherein, Figure 3A Point A in the middle and Figure 3B The complete device architecture diagram of this embodiment is shown below, with point B connected to it. Figure 3A and Figure 3BAs shown, the device includes a hydrogen storage module 111, a power generation module 112, and a power supply module 113. The hydrogen storage module 111 includes a hydrogen cylinder group for storing hydrogen, a hydrogen detection device for monitoring hydrogen leakage in real time and ensuring hydrogen storage safety, and related valves, pipes, etc. for realizing the delivery and control of hydrogen. The power generation module 112 integrates components such as a fuel cell stack FCK, a power conversion system (PCS), a DC-DC converter module (DCM), a battery pack (BATT), and a fuel cell control unit (FCU). The power supply module 113 includes multiple charging interfaces and can provide the power generated or processed by the power generation module 220 to the devices to be charged (such as electric vehicles, etc.) to meet the charging needs of different devices.

[0077] Optionally, the hydrogen stored in the hydrogen storage module 111 is delivered to the power generation module 112 through pipes, etc. The power generation module 220 uses this hydrogen to generate electricity under the action of core components such as a fuel cell stack, and converts hydrogen energy into electrical energy. At the same time, the power generation module 112 will reasonably schedule the amount of hydrogen obtained from the hydrogen storage module 210 according to its own operation needs and interaction with the second battery module, etc. to ensure the continuity and stability of the power generation process. Then, the electrical energy generated by the power generation module 112 is transmitted to the power supply module 113 after being processed by the power conversion system PCS, the DC-DC converter module DCM, etc. so that the power supply module 113 provides the processed electrical energy to the devices to be charged.

[0078] Figure 4A The structure diagram of the electric control module provided by an embodiment of the present application is schematically shown. The electric control module is arranged in the power generation module of the hydrogen-electric coupling system, as shown in Figure 4A The electric control module takes a programmable logic controller (PLC) as the core, realizes remote communication with an external energy supervision platform through a switch, and then realizes local communication with a gas controller, a flame controller, a pressure regulating system, a fuel cell system, etc. through a communication interface module 1 and a communication interface module 2. The front end thereof not only includes sensing devices such as a smoke sensor, a temperature sensor, a gas probe, a flame probe, etc. for collecting safety and operation parameters, but also includes execution devices such as a carbon dioxide extinguishing device, a lighting machine, a fan, and various controllers, etc.

[0079] Optionally, the PLC control cabinet can centrally process various data and issue control instructions, realize centralized control of the hydrogen-electricity coupling system, and use sensing devices to monitor smoke, temperature, fuel gas, and flame, trigger actions such as fire extinguishing and fuel gas shutoff, and ensure safety. On the other hand, the PLC control cabinet can also control lighting and fans through local and remote communication to provide environmental protection for system operation, and meet the needs of local control and remote monitoring and scheduling.

[0080] Figure 4B A control logic diagram provided by an embodiment of the application is schematically shown. As shown in Figure 4B the system is running normally, the electronic control module will continuously monitor hydrogen leakage, smoke, temperature, emergency stop button state, fuel cell system failure, battery over-temperature, and flame. If any of these conditions is detected, such as hydrogen leakage, smoke, temperature rise, emergency stop button press, fuel cell system failure, battery over-temperature, the safety measures of sound and light alarm start, automatic closing of the hydrogen inlet valve, fan start, and device interlocking shutdown will be triggered. If a flame alarm is detected, in addition to the above safety measures, the carbon dioxide fire extinguishing system will also be started, so as to ensure that the system can respond in time when various safety hazards occur, and avoid the expansion of the accident.

[0081] Figure 5 A method flowchart provided by an embodiment of the application is schematically shown. As shown in Figure 5 the execution flow of the embodiment includes: Step 501: The power supply device is powered on, and the hydrogen-electricity coupling system automatically enters a start-up flow.

[0082] Step 502: The hydrogen-electricity coupling system performs self-checking to check whether the hydrogen storage module, the power generation module, and each unit are working normally. After self-checking is completed, hydrogen is used to purge the anode of the fuel cell stack in the first battery module. The purging time is less than 10s, and the amount of hydrogen used is less than 60NL. After the anode purging is completed, the air compressor is started to perform cathode purging, and the purging time is less than 10s. After the anode and cathode purging are respectively completed, the power generation stage is started.

[0083] Step 503: Continuously detect whether the hydrogen-electricity coupling system has a fault. If a fault is detected, the operation of the hydrogen-electricity coupling system is stopped, and fault information is displayed in the interactive interface.

[0084] Step 504: Obtain the power supply parameters of the external power grid.

[0085] Step 505: Determine the control mode according to the power supply parameters of the external power grid, the control mode including a first control mode and a second control mode.

[0086] If the control mode is the first control mode, the hydrogen fuel cell in the first battery module is used to supply power to the external power grid and the device to be charged; if the control mode is the second control mode, the state of charge (SOC) of the lithium battery in the second battery module is obtained, and the power supply mode is determined according to the state of charge: when the SOC of the lithium battery is in a first threshold interval 10% < SOC < 40%, the first battery module is used for power supply alone; when the SOC of the lithium battery is in a second threshold interval 40% < SOC < 95%, one of the second battery module and the first battery module is selected for power supply; when the SOC of the lithium battery is in a third threshold interval SOC > 95%, the lithium battery in the second battery module is used for power supply alone. In addition, when the SOC of the lithium battery is less than 30%, the lithium battery in the second battery module also stops outputting alternating current without starting the first battery module.

[0087] If the first battery module is selected for power supply alone, a control instruction of a user is received, and the control instruction includes a first battery module starting command and a working mode of the first battery module. When the user selects the working mode of the first battery module as a manual mode, i.e., a first working mode, and sets the power generation power of the first battery module, the first battery module will generate power at a constant power according to the power generation power set by the user; when the user selects the working mode of the first battery module as an automatic mode, i.e., a second working mode, the first battery module will automatically adjust the power generation power of the first battery module according to the SOC of the lithium battery.

[0088] In the technical scheme provided in the embodiments of the present application, the hydrogen-electricity coupling system is automatically started after power-on, and the first battery module anode and cathode are quickly purged, which greatly shortens the system starting time, reduces the hydrogen loss, and further improves the system response efficiency. During system operation, continuous fault detection and synchronous display of fault information are performed, which can timely interrupt the risk operation, facilitate rapid troubleshooting, and ensure the safety of equipment and personnel. Then, the power supply parameters of the external power grid are obtained, and the control mode is determined according to the power supply parameters to dynamically adjust the power supply logic. On the one hand, the hydrogen-electricity converted power is reasonably distributed to the external power grid and the device to be charged, which maximizes the use of hydrogen-electricity resources. On the other hand, the abnormal power grid can also avoid interfering with the power supply process, thereby improving the power supply stability.

[0089] In addition, the first battery module supports two modes of manual mode and automatic mode, which can not only meet the individual power demand of the user, but also dynamically adjust the power generation power to ensure the power stability of the device to be charged and the continuous operation of the auxiliary equipment, thereby realizing the collaborative optimization of system power supply efficiency, equipment life and power stability.
