Description

Technical Field

[0001] This invention relates to the field of charging pile technology, and in particular to a charging control method, device, equipment, and storage medium for a charging system. Background Technology

[0002] With the development of charging pile technology, there are more and more types of charging piles on the market. For example, there are DC charging piles or AC charging piles that can only be powered by the mains power grid or energy storage devices. There are also some charging piles that use clean energy, such as photovoltaic charging piles. Charging piles that use mains power are mainly powered by thermal power, which produces a lot of carbon dioxide emissions during the power supply process. Although photovoltaic charging piles do not produce carbon dioxide, they also do not consume carbon dioxide.

[0003] Currently, nano-photocatalytic coatings based on perovskite materials modified with nano-titanium oxide have emerged. Under visible light irradiation, these coatings generate photogenerated electron-hole pairs, capturing carbon dioxide and water vapor from the air and then photocatalytically converting them into hydrocarbons (such as methanol), while simultaneously releasing electrical energy. Several technologies have already been developed to produce photosynthetic modules based on this principle. These modules, along with the mains power grid, serve as dual power sources for photosynthetic charging stations. Under sufficient sunlight, these modules generate electricity through photosynthesis, consuming atmospheric carbon dioxide and thus reducing carbon dioxide emissions.

[0004] However, current photovoltaic charging stations can only operate independently. After an electric vehicle is connected to the photovoltaic charging station, the charging power is determined according to the vehicle type. When the output power of the photovoltaic components cannot meet the charging demand, it is still necessary to switch to the mains power grid for power supply. When the charging power demand is large, the carbon dioxide consumption efficiency is not good. Summary of the Invention

[0005] This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention proposes a charging control method, device, equipment, and storage medium for a charging system, which can utilize multiple photosynthetic charging piles to coordinately respond to a charging demand, thereby increasing the proportion of photosynthetic power generation and improving carbon dioxide consumption efficiency.

[0006] In a first aspect, embodiments of the present invention provide a charging control method for a charging system. The charging system includes a photosynthetic power grid and multiple photosynthetic charging piles. Each photosynthetic charging pile includes a charging cable, a photosynthetic component, and a switching device. The switching device includes an output end, a first end, a second end, and a third end. The output end is connected to the charging cable, the first end is connected to the photosynthetic component, the second end is connected to the photosynthetic power grid, and the third end is connected to the mains power grid. The method includes:

[0007] In response to a charging request from a first charging pile, a first charging power of the first charging pile is determined, a first output power of one of the photosynthetic components is determined, and a first power difference between the first charging power and the first output power is determined.

[0008] When the first power difference is greater than zero, a first quantity is determined based on the first power difference and the first output power, and a second quantity of available charging piles that have not been started is determined.

[0009] When the first quantity is less than or equal to the second quantity, the switching device of the first charging pile is set to a first state; or when the first quantity is greater than the second quantity, the switching device of the first charging pile is set to a second state. The first state indicates that the output terminal is connected to the first terminal and the second terminal, and the second state indicates that the output terminal is connected to the first terminal, the second terminal and the third terminal.

[0010] Based on the first quantity, a plurality of second charging piles are determined from the plurality of available charging piles, and the switching device of the second charging piles is set to a third state, wherein the third state indicates that the first end is connected to the second end;

[0011] The first charging pile is activated to start charging, and the second charging pile is activated to generate electricity through photosynthesis.

[0012] According to some embodiments of the present invention, the photosynthetic component includes a photocatalytic power generation module and a carbon capture and storage module. The photocatalytic power generation module is capable of generating electricity and producing methanol based on a photocatalytic reaction. The raw materials for the photocatalytic reaction are water vapor and carbon dioxide from the atmosphere. The carbon capture and storage module includes a storage tank and a fuel cell. The storage tank is used to store the methanol generated by the photocatalytic power generation module, and the fuel cell generates electricity based on the methanol in the storage tank. Determining a first output power of the photosynthetic component includes:

[0013] The photosynthetic power generation and catalytic power consumption of the photocatalytic power generation module are determined in real time based on the real-time light intensity. The photosynthetic power generation is the power of the photocatalytic reaction to generate electrical energy, and the catalytic power consumption is the power used to drive the photocatalytic reaction. The raw materials for the photocatalytic reaction are water vapor and carbon dioxide.

[0014] The difference between the photosynthetic power generation and the catalytic power consumption is determined as the second output power;

[0015] The sum of the second output power and the third output power of the fuel cell is determined as the first output power.

[0016] According to some embodiments of the present invention, determining a first quantity based on the first power difference and the first output power includes:

[0017] The third quantity is determined based on the ratio of the first power difference to the second output power;

[0018] When the third quantity is less than or equal to the second quantity, the third quantity is determined as the first quantity;

[0019] When the third quantity is greater than the second quantity, the first quantity is determined based on the first power difference, the second output power, and the third output power.

[0020] According to some embodiments of the present invention, determining the first quantity based on the first power difference, the second output power, and the third output power includes:

[0021] The fourth output power is determined based on the second quantity and the second output power, and the second power difference between the first power difference and the fourth output power is determined.

[0022] A fourth quantity is obtained based on the ratio of the second power difference and the third output power. When the fourth quantity is less than or equal to the second quantity, the larger of the fourth quantity and the third quantity is determined as the first quantity; otherwise, the third quantity is determined as the first quantity.

[0023] According to some embodiments of the present invention, after setting the switching device of the second charging pile to the third state, the method further includes:

[0024] The photocatalytic power generation module of multiple second charging piles is activated based on the first quantity;

[0025] The fuel cells of multiple second charging piles are activated based on the fourth quantity;

[0026] Record the current second output power as the reference output power;

[0027] The second output power is updated in real time based on the real-time light intensity.

[0028] When it is detected that the absolute value of the difference between the real-time second output power and the reference output power is greater than the third output power, the first quantity is re-determined, and the operating status of the multiple second charging piles is updated based on the re-determined first quantity.

[0029] According to some embodiments of the present invention, after setting the switching device of the second charging pile to the third state, the method further includes:

[0030] In response to a charging request from a third charging pile, a second charging power of the third charging pile is determined, and a third power difference between the second charging power and the first output power is determined, wherein the third charging pile is any second charging pile or the available charging pile;

[0031] Based on the third power difference and the first output power, a fifth quantity is determined, and the current second quantity is re-determined;

[0032] When the fifth quantity is less than or equal to the current second quantity, the switching device of the third charging pile is set to the first state and charging is started. Based on the fifth quantity, a plurality of fourth charging piles are determined from the plurality of available charging piles, and the fourth charging piles are started to generate photosynthetic power.

[0033] Alternatively, when the fifth quantity is greater than the current second quantity, all the fourth charging piles are activated for photosynthetic power generation, and the switching device of the third charging pile is set to the first state or the second state based on the operating status of the multiple second charging piles.

[0034] According to some embodiments of the present invention, setting the switching device of the third charging pile to the first state or the second state based on the operating states of the plurality of second charging piles includes:

[0035] When all the fuel cells of the second charging piles are in operation, the switching device of the third charging pile is set to the second state;

[0036] Alternatively, when the fuel cell of at least one of the second charging piles is in standby mode, the product of the second quantity and the first output power is determined as the fifth output power, the fourth power difference between the second charging power and the fifth output power is determined, and the sixth quantity is determined based on the ratio of the fourth power difference to the third output power.

[0037] When the sixth quantity is greater than the number of the second charging piles in standby state of the fuel cell, the switching device of the third charging pile is set to the second state;

[0038] Alternatively, when the sixth quantity is less than or equal to the number of the second charging piles in standby mode of the fuel cell, the switching device of the third charging pile is set to the first state.

[0039] In a second aspect, embodiments of the present invention provide a charging control device for a charging system, including at least one control processor and a memory for communicatively connecting to the at least one control processor; the memory stores instructions executable by the at least one control processor, the instructions being executed by the at least one control processor to enable the at least one control processor to perform the charging control method of the charging system as described in the first aspect above.

[0040] Thirdly, embodiments of the present invention provide an electronic device including a charging control device for a charging system as described in the second aspect above.

[0041] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing computer-executable instructions for performing a charging control method for a charging system as described in the first aspect above.

According to the technical solution of the present invention, when the charging demand of a single photosynthetic charging pile is greater than the power generation of a single photosynthetic module, multiple idle photosynthetic charging piles can work together to supply power via their photosynthetic modules, thereby reducing the intervention of mains power, maximizing the use of photosynthetic modules to absorb carbon dioxide, increasing the proportion of photosynthetic power generation, and improving the efficiency of carbon dioxide consumption.

[0047] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0048] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0049] In the description of this invention, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0050] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0051] This invention provides a charging control method, apparatus, device, and storage medium for a charging system. The charging control method includes: responding to a charging request from a first charging pile; determining a first charging power of the first charging pile; determining a first output power of a photosynthetic component; and determining a first power difference between the first charging power and the first output power. When the first power difference is greater than zero, determining a first quantity based on the first power difference and the first output power; and determining a second quantity of available charging piles that are not yet activated. When the first quantity is less than or equal to the second quantity, setting the switching device of the first charging pile to a first state; or, when the first quantity is greater than the second quantity, setting the switching device of the first charging pile to a second state. The first state indicates that the output terminal is connected to the first end and the second end, and the second state indicates that the output terminal is connected to the first end, the second end, and the third end. Based on the first quantity, determining a plurality of second charging piles from the plurality of available charging piles; setting the switching device of the second charging pile to a third state, where the third state indicates that the first end is connected to the second end. The first charging pile is activated for charging, and the second charging piles are activated for photosynthetic power generation. According to the technical solution of the present invention, when the charging demand of a single photosynthetic charging pile is greater than the power generation of a single photosynthetic module, multiple idle photosynthetic charging piles can work together to supply power via their photosynthetic modules, thereby reducing the intervention of mains power, maximizing the use of photosynthetic modules to absorb carbon dioxide, increasing the proportion of photosynthetic power generation, and improving the efficiency of carbon dioxide consumption.

[0052] First, refer to Figure 1 and Figure 3 , Figure 1 This is a schematic diagram of a charging system provided in an embodiment of the present invention. Figure 3 The diagram shows the state of the switching device 30. The charging system in this embodiment includes a photosynthetic line network 40 and multiple photosynthetic charging piles. Each photosynthetic charging pile includes a charging cable 10, a photosynthetic component, and a switching device 30. The switching device 30 includes an output end 31, a first end 32, a second end 33, and a third end 34. The output end 31 is connected to the charging cable 10, the first end 32 is connected to the photosynthetic component, the second end 33 is connected to the photosynthetic line network 40, and the third end 34 is connected to the mains power network 50.

[0053] It should be noted that the charging cable 10 of the photovoltaic charging pile has a common structure. In this embodiment, a switching device 30 is built into the photovoltaic charging pile. The output terminal 31 of the switching device 30 is connected to the charging cable 10, thereby providing power to the charging cable 10. The switching device 30 can be a common multi-channel switch device. The switching device 30 is provided with an output terminal 31, a first terminal 32, a second terminal 33, and a third terminal 34. The output terminal 31 is provided with an independent connection structure between the first terminal 32, the second terminal 33, and the third terminal 34. Each connection structure can be turned on or off independently under control. At the same time, a connection structure is also provided between the first terminal 32 and the second terminal 33.

[0054] like Figure 1 and 3 As shown, the switching device 30 in this embodiment includes three states. In the first state, the output terminal 31 is connected to the first terminal 32 and the second terminal 33, so that the electrical energy of the photosynthetic component of the photosynthetic charging pile itself enters the charging cable 10 through the first terminal 32 and the output terminal 31, and obtains photosynthetic electrical energy provided by other photosynthetic charging piles from the photosynthetic circuit network 40 through the second terminal 33. In the second state, the output terminal 31 is connected to the first terminal 32, the second terminal 33 and the third terminal 34 respectively, so that the photosynthetic component, the photosynthetic circuit network 40 and the mains power network 50 simultaneously supply power to the charging cable 10 through the output terminal 31, and the photosynthetic charging pile provides charging power to the vehicle at its maximum capacity. In the third state, only the first terminal 32 and the second terminal 33 are connected, and the output terminal 31 is in the disconnected state. At this time, the electrical energy generated by the photosynthetic component enters the photosynthetic circuit network 40 through the second terminal 33 to provide power to other photosynthetic charging piles.

[0055] It should be noted that the charging system in this embodiment has multiple photosynthetic charging piles, and therefore multiple switching devices 30. In this embodiment, the second end 33 of each switching device 30 is connected through a photosynthetic line network 40, providing a basis for the coordinated charging of multiple photosynthetic charging piles. The third end 34 of each switching device 30 is connected to the mains power network 50, providing power guarantee when the charging demand cannot be met even with the coordinated efforts of multiple photoelectric components, or when all photosynthetic charging piles are in a charging state.

[0056] It should be noted that the photosynthetic component includes a photocatalytic power generation module 20 and a carbon capture and storage module 21. The photocatalytic power generation module 20 can generate methanol based on a photocatalytic reaction. The raw materials for the photocatalytic reaction are water vapor and carbon dioxide in the atmosphere. The carbon capture and storage module 21 includes a storage tank 211 and a fuel cell 212. The storage tank 211 is used to store the methanol generated by the photocatalytic power generation module 20, and the fuel cell 212 generates electricity based on the methanol in the storage tank 211.

[0057] It should be noted that the photosynthetic module can adopt the structure of existing technology. For example, a light-transmitting gas collection hood can be set on the top of the photocatalytic power generation module 20. When the carbon dioxide concentration reaches a preset concentration, the air intake fan will automatically turn on. A nano-catalytic coating (titanium oxide-perovskite composite film, 500nm thick) is covered on the inner side of the light-transmitting gas collection hood. The nano-catalytic coating absorbs photons to generate electron-hole pairs. A metal electrode is set at the bottom of the light-transmitting gas collection hood to collect photogenerated electrons. Below the nano-catalytic coating is the catalytic reaction chamber. After water vapor and carbon dioxide are introduced, a photocatalytic reaction occurs. Under sufficient light, the hole pairs oxidize the water vapor to oxygen, and the electrons reduce carbon dioxide to methanol. At the same time, the electrons output direct current (voltage 12-24V) through the electrodes. That is, the products of the reaction between carbon dioxide and water are methanol, oxygen, and electrical energy.

[0058] It should be noted that the storage tank 211 of the carbon capture and storage module 21 is used to collect the methanol produced in the above reaction. Since methanol can be burned, a fuel cell 212 is simultaneously configured in the carbon capture and storage module 21. The fuel cell is powered by the methanol stored in the storage tank 211. The fuel cell 212 is a common existing product and will not be described in detail here.

[0059] The following is based on the appendix Figure 1 The charging system shown further illustrates the technical solution of this embodiment of the invention.

[0060] Reference Figure 2 , Figure 2 This is a flowchart of a charging control method for a charging system provided in an embodiment of the present invention. The charging control method includes, but is not limited to, the following steps:

[0061] S10, in response to the charging request of the first charging pile, determine the first charging power of the first charging pile, determine the first output power of a photosynthetic component, and determine the first power difference between the first charging power and the first output power.

[0062] It should be noted that the charging request of the first charging pile is initiated after the electric vehicle is connected to the charging cable and charging is started. If the electric vehicle initiates a scheduled charging through the vehicle's infotainment system or an app, the charging request will be initiated after the scheduled charging time has arrived. After the electric vehicle starts charging, there will be a period of time for matching the charging gun and the vehicle. Therefore, starting charging and charging are not at the same time. The technical solution of this embodiment can be executed within this matching time period. The control system of the charging system can execute the technical solution of this embodiment according to the operating status of multiple charging piles. Charging can start only after multiple second charging piles are determined.

[0063] It should be noted that the first charging power is determined based on the parameters of the vehicle connected to the first charging pile. Of course, when the rated power of the vehicle exceeds the rated power of the first charging pile, the first charging power is the rated power of the first charging pile.

[0064] It should be noted that this embodiment involves photosynthetic power generation, therefore it can be understood that all photosynthetic charging piles must be installed in outdoor parking lots. The charging system in this embodiment is a cluster of photosynthetic charging piles in a relatively small area. This area can be an outdoor parking lot of a residential community, or multiple outdoor parking lots that are relatively close to each other. It is essential to ensure that the lighting conditions of the multiple photosynthetic charging piles in the charging system are consistent. If the area corresponding to the charging system is too large, it is easy for the lighting intensity of two photosynthetic charging piles that are far apart to be inconsistent due to weather conditions, which would prevent the calculation process of this embodiment from being executed. This scenario is not within the scope of this embodiment. The scenario in this embodiment is that the lighting intensity of all photosynthetic charging piles is the same. Based on this, the first output power of each photosynthetic component is the same under the same lighting intensity. When the first charging pile is started, the first output power is determined by the lighting intensity detected in real time by the photosynthetic component of the first charging pile, or by directly obtaining the first output power of the photosynthetic components of other photosynthetic charging piles that are charging in the same charging system. This will not result in different values ​​of the first output power.

[0065] It should be noted that, since the photosynthetic charging pile in this embodiment can be powered by the mains network, the first charging power can be greater than the first output power. The difference between the first charging power and the first output power is the first power difference, which is used for subsequent processing.

[0066] S20, when the first power difference is greater than zero, determine the first quantity based on the first power difference and the first output power, and determine the second quantity of available charging piles that have not been started.

[0067] It should be noted that when the first power difference is less than or equal to zero, the photosynthetic power generation of the photosynthetic module is already sufficient to meet the first charging power, and this scenario is not within the scope of this embodiment.

[0068] It should be noted that since the output power of each photosynthetic component is the same, the first quantity obtained by the ratio of the first power difference to the first output power is the number of additional photosynthetic components that need to be activated to meet the first charging power. The first quantity does not include the photosynthetic components of the first charging pile. When the first quantity is not an integer, it can be rounded up.

[0069] It should be noted that available charging piles are photosynthetic charging piles that have not yet started charging. The number of available charging piles can be determined as the second number. Available charging piles are not limited to those whose charging cables are not connected to the electric vehicle. In this embodiment, the photosynthetic charging piles are equipped with a switching device. In the third state, the electrical energy generated by the photosynthetic components of the charging pile does not enter the charging cable, but instead enters the photosynthetic charging network through the second end of the switching device. This allows other photosynthetic charging piles in the first or second state to utilize this electrical energy. Therefore, the available charging piles in this embodiment also include photosynthetic charging piles that are in the reservation waiting stage and have not yet started charging. Once these photosynthetic charging piles start charging at the scheduled time, they are no longer designated as second charging piles; a second charging pile can be determined from the remaining available charging piles.

[0070] S30, when the first quantity is less than or equal to the second quantity, the switching device of the first charging pile is set to the first state, or when the first quantity is greater than the second quantity, the switching device of the first charging pile is set to the second state, wherein the first state indicates that the output terminal is connected to the first terminal and the second terminal, and the second state indicates that the output terminal is connected to the first terminal, the second terminal and the third terminal.

[0071] It should be noted that when the first quantity is less than or equal to the second quantity, it can be determined that a system relying solely on multiple photosynthetic components can meet the first charging power requirement, without the need for an external power grid. (Refer to...) Figure 1 and Figure 3 As shown, the switching device 30 of the first charging pile is set to the first state. At this time, the first charging pile can obtain power from its own photosynthetic components through the first end 32 of the switching device 30, and at the same time obtain power from the photosynthetic power grid 40 through the second end 33. In this scenario, power is provided to the first charging pile only through the cooperation of multiple photosynthetic components, so as to achieve the maximum utilization rate of photosynthetic power generation. By absorbing carbon dioxide to generate electricity, carbon dioxide in the atmosphere is reduced, and no grid power is introduced, which improves the utilization rate of photosynthetic power generation and improves the emission reduction effect.

[0072] It should be noted that the first quantity actually represents the shortage of photosynthetic modules to meet the first charging power requirement, while the second quantity actually represents the number of photosynthetic modules currently available for coordination. When the first quantity is greater than the second quantity, it can be determined that even coordinating all available charging stations cannot meet the first charging power requirement. (Refer to...) Figure 1 and 3As shown, the switching device 30 of the first charging pile is switched to the second state. The first charging pile can obtain photosynthetic power from its own photosynthetic components through the first end 32, obtain photosynthetic power from the photosynthetic components of other second charging piles through the second end 33 and the photosynthetic power line network 40, and obtain mains power from the mains power network 50 through the third end 34 as a supplement. Since all available charging piles are activated, the power generated by photosynthesis can be utilized to the maximum extent. The mains power is only used as a supplement to the insufficient photosynthetic power, which effectively improves the utilization rate of photosynthetic power generation and improves the emission reduction effect.

[0073] S40, based on a first quantity, determine a plurality of second charging piles from a plurality of available charging piles, and set the switching device of the second charging piles to a third state, wherein the third state indicates that the first end is connected to the second end.

[0074] It should be noted that after determining the first quantity, if the first quantity is less than or equal to the second quantity, then multiple second charging piles can be randomly selected from the available charging piles according to the first quantity, that is, the number of second charging piles is equal to the first quantity; if the first quantity is greater than the second quantity, then all available charging piles will be selected as second charging piles.

[0075] It should be noted that the second charging station itself does not perform charging; instead, it provides power to the first charging station through a photosynthetic component. Therefore, the switching device for the second charging station is set to the third state, such as... Figure 1 and Figure 3 As shown, in the third state, the first end 32 of the switching device 30 is connected to the second end 33, so that the electrical energy of the photosynthetic component of the second charging pile enters the photosynthetic circuit network 40 through the first end 32 and the second end 33, thereby providing electrical energy to the first charging pile.

[0076] S50, start the first charging pile to charge, start the second charging pile to generate electricity through photosynthesis.

[0077] It should be noted that after determining multiple second charging piles according to the above embodiment, the second charging piles are activated to generate electricity through photosynthesis, and the electricity generated by the photosynthesis is input to the first charging pile for charging through the photosynthesis line network.

[0078] It should be noted that the first charging pile in this embodiment is a photosynthetic charging pile in a charging state. There can be multiple first charging piles in the charging system. After the electrical energy generated by the second charging pile enters the photosynthetic network, it may enter other first charging piles for charging. However, since this embodiment is based on the power difference calculation, as long as the power of the electrical energy input in the photosynthetic network is determined based on the power of each first charging pile, it can be ensured that each first charging pile can obtain sufficient power.

[0079] In another embodiment, in step S10, determining the first output power of a photosynthetic component specifically includes, but is not limited to, the following steps:

[0080] S11, the photosynthetic power generation and catalytic power consumption of the photocatalytic power generation module are determined in real time based on the real-time light intensity. The photosynthetic power generation is the power of the photocatalytic reaction to generate electricity, and the catalytic power consumption is the power used to drive the photocatalytic reaction. The raw materials for the photocatalytic reaction are water vapor and carbon dioxide.

[0081] S12, the difference between photosynthetic power generation and catalytic power consumption is determined as the second output power;

[0082] S13, the sum of the second output power and the third output power of the fuel cell is determined as the first output power.

[0083] It should be noted that since the intensity of natural light is not constant, this embodiment cannot use some set values ​​as power calculations. Instead, it determines the photosynthetic power generation and catalytic power consumption of the photocatalytic power generation module based on the real-time light intensity. Given that the hardware parameters of the photocatalytic power generation module are known, those skilled in the art know how to convert light intensity into photosynthetic power generation and catalytic power consumption.

[0084] It should be noted that electrical energy is required during the photocatalytic reaction. In the initial stage, the power of the fuel cell can be used for power supply. After the photocatalytic reaction is started, the power generated by the photocatalytic reaction itself can be used for feedback power supply. Therefore, in this embodiment, the difference between the photosynthetic power generation power and the catalytic power consumption power is first determined as the second output power. The second output power is the net output power of the photocatalytic power generation module.

[0085] It should be noted that, as Figure 1 As shown, the photosynthetic module also includes a fuel cell 212. The fuel cell 212 can generate electricity using methanol produced by the photocatalytic power generation module 20 as fuel. Although the combustion of methanol will produce a certain amount of carbon dioxide, since the methanol in the storage tank 211 is all a product of the photocatalytic reaction, the carbon dioxide produced under the constraint of mass conservation will inevitably be less than the carbon dioxide consumed during the photocatalytic reaction. Therefore, the photosynthetic module can also achieve carbon dioxide consumption in general. Therefore, the maximum output power of the photosynthetic module in this embodiment is the sum of the net output power of the photocatalytic power generation module and the output power of the fuel cell, that is, the first output power is the sum of the second output power and the third output power.

[0086] In another embodiment, in step S20, the first quantity is determined based on the first power difference and the first output power, which specifically includes, but is not limited to, the following steps:

[0087] S21, determine the third quantity based on the ratio of the first power difference and the second output power;

[0088] S22, when the third quantity is less than or equal to the second quantity, the third quantity is determined as the first quantity;

[0089] S23, when the third quantity is greater than the second quantity, the first quantity is determined based on the first power difference, the second output power and the third output power.

[0090] It should be noted that the first power difference is the charging power gap of the first charging pile, and the second output power is the net output power of the photocatalytic power generation module. Therefore, the ratio of the two yields the third quantity. Since the combustion of fuel cells will produce carbon dioxide to a certain extent, in order to minimize the production of carbon dioxide, this embodiment uses the third quantity to characterize the number of photosynthetic components required for charging coordination solely by the photocatalytic power generation module without starting the fuel cell. That is, the first power difference is satisfied when each second charging pile only starts the photocatalytic power generation module.

[0091] When the third quantity is less than or equal to the second quantity, it can be determined that activating only the photocatalytic power generation modules of multiple second charging piles can also satisfy the first power difference. The third quantity is determined as the first quantity. In this embodiment, the third quantity is less than or equal to the second quantity as the triggering basis. As long as the above triggering condition is met, only the photocatalytic power generation module is activated when the photosynthetic components of the second charging pile are activated, and the fuel cell is not activated.

[0092] When the third quantity is greater than the second quantity, the first power difference cannot be met by relying solely on the photocatalytic power generation module. In this case, the first quantity needs to be determined based on the first power difference, the second output power, and the third output power. This determines that multiple second charging piles only use the photocatalytic power generation module. Multiple second charging piles simultaneously start the photocatalytic power generation module and the fuel cell to ensure that multiple second charging piles work together to provide the power represented by the first power difference through the photosynthetic component.

[0093] In another embodiment, step S23 specifically includes, but is not limited to, the following steps:

[0094] S231, determine the fourth output power based on the second quantity and the second output power, and determine the second power difference between the first power difference and the fourth output power;

[0095] S232, based on the ratio of the second power difference and the third output power, a fourth quantity is obtained. When the fourth quantity is less than or equal to the second quantity, the larger of the fourth quantity and the third quantity is determined as the first quantity; otherwise, the third quantity is determined as the first quantity.

[0096] It should be noted that the second quantity refers to the number of available charging stations, and the second output power refers to the net output power of the photocatalytic power generation module. Therefore, the fourth output power, obtained by multiplying the second quantity and the second output power, is the sum of the power of the photocatalytic power generation modules of all available charging stations. The second power difference, obtained by subtracting the first power difference from the fourth output power, represents the power gap after all available photocatalytic power generation modules have been activated.

[0097] It should be noted that after obtaining the second power difference, the third output power is the output power of a single fuel cell. Therefore, in this embodiment, the ratio of the second power difference to the third output power is rounded up to obtain the fourth quantity. The fourth quantity is the number of fuel cells required to fill the power gap. When the fourth quantity is less than or equal to the second quantity, it can be determined that there are enough fuel cells to fill the power gap represented by the second power difference. The larger of the fourth and third quantities is determined as the first quantity, ensuring that enough photocatalytic charging modules and / or fuel cells are activated. Then, subsequent steps are performed according to the relationship between the first and second quantities. When the fourth quantity is greater than the second quantity, there are not enough fuel cells to fill the power gap represented by the second power difference. In this case, the third quantity is actually equal to the second quantity, and all available charging piles are determined as the second charging piles.

[0098] In another embodiment, after step S40 is completed, the method further includes, but is not limited to, the following steps:

[0099] S411, based on the first quantity, activate the photocatalytic power generation module of multiple second charging piles;

[0100] S412, a fuel cell that starts multiple second charging stations based on the fourth quantity;

[0101] S413, record the current second output power as the reference output power;

[0102] S414 updates the second output power in real time based on the real-time light intensity;

[0103] S415, when it is detected that the absolute value of the difference between the real-time second output power and the reference output power is greater than the third output power, the first quantity is re-determined, and the operating status of multiple second charging piles is updated based on the re-determined first quantity.

[0104] It should be noted that, after determining the first quantity and the fourth quantity, according to the description of the above embodiments, the fourth quantity must be less than or equal to the first quantity. Therefore, in this embodiment, the photocatalytic power generation modules of multiple second charging piles are first activated to start photosynthetic power generation based on the first quantity, and then the fuel cells of multiple second charging piles are randomly activated based on the fourth quantity. In this embodiment, the first quantity and the fourth quantity are stored in the charging system. Even if, according to the description of the above embodiments, the first quantity may be determined based on the fourth quantity, the corresponding parameters can still be obtained to activate the relevant modules.

[0105] It should be noted that since light intensity varies over time, the operating status of each photosynthetic charging pile determined at startup cannot guarantee its maintenance throughout the day. Therefore, in this embodiment, the determined second output power is recorded as a reference power each time, and then the second output power is updated according to the real-time light intensity. Since the second output power is the sum of the output power of the photocatalytic power generation modules, and the third output power is the output power of a single fuel cell, when the difference between the second output power and the reference power is greater than the third output power, it can be determined that the first charging power can no longer be met by the photocatalytic power generation modules as the light intensity decreases. In this embodiment, this is used as a trigger to re-determine the first quantity, and the re-determination of the first quantity triggers the technical solutions of the above embodiments to be re-executed once, thereby re-determining the operating status of multiple second charging piles. For example, a fourth quantity can be added to increase the number of fuel cells, or when the first quantity meets the condition, the switching device of the first charging pile can switch to the second state to introduce mains power, etc. For specific principles, please refer to the description of the above embodiments.

[0106] In another embodiment, after step S40 is completed, the method further includes, but is not limited to, the following steps:

[0107] S421, in response to a charging request from a third charging pile, determine the second charging power of the third charging pile, and determine the third power difference between the second charging power and the first output power, wherein the third charging pile is any second charging pile or an available charging pile;

[0108] S422, determine the fifth quantity based on the third power difference and the first output power, and redetermine the current second quantity;

[0109] S423, when the fifth quantity is less than or equal to the current second quantity, the switching device of the third charging pile is set to the first state and charging is started. Based on the fifth quantity, multiple fourth charging piles are determined from multiple available charging piles, and the fourth charging piles are started to generate electricity through photosynthesis.

[0110] S424, when the fifth quantity is greater than the current second quantity, all fourth charging piles are activated for photosynthetic power generation, and the switching device of the third charging pile is set to the first state or the second state based on the operating status of multiple second charging piles.

[0111] It should be noted that when the first charging pile is in the charging state, although the photosynthetic component of the second charging pile is running, the second charging pile is not actually connected to an electric vehicle. Therefore, the second charging pile or any available charging pile that is not identified as the second charging pile can be connected to the vehicle to initiate a charging request. In this embodiment, each newly added photosynthetic charging pile that starts charging, other than the first charging pile, is identified as the third charging pile.

[0112] It should be noted that the second charging power of the third charging pile is similar to the first charging power, the third power difference is similar to the first power difference, and the fifth quantity is similar to the first quantity, so they will not be repeated here. The second quantity is the number of available charging piles when the photosynthetic module is in an idle state. When an available charging pile is identified as the third charging pile, the second quantity changes. Therefore, after removing the third charging pile, the number of available charging piles that were not identified as the second charging pile is updated to the second quantity.

[0113] It should be noted that when the fifth quantity is less than or equal to the current second quantity, the remaining available charging piles can meet the second charging power. The principle of the fourth charging pile can refer to the principle of the second charging pile mentioned above. The switching device of the third charging pile can also refer to the principle of the first charging pile when set to the first state. Therefore, step S423 will not be repeated here.

[0114] In step S424, when the fifth quantity is greater than the current second quantity, the multiple fourth charging piles cannot meet the third power difference. At this time, it is not necessarily necessary to introduce mains power. This is because the fourth charging piles are not part of the second charging piles. The current charging system also includes multiple second charging piles. According to the description of the above embodiment, the second charging piles may only have activated the photocatalytic power generation module. If the fuel cell of the second charging pile can make up for the gap of the third power difference, since the second end of the switching device of all the photosynthetic charging piles is connected to the photosynthetic power grid, it is only necessary for the sum of the input power of the photosynthetic power grid to meet the sum of all charging power. In fact, it can also be shared. That is, in this embodiment, multiple cooperating second charging piles that were not determined at the time of starting charging can be used as a supplement to the third charging pile, so as to make full use of the resources of the photosynthetic components when prioritizing the use of photosynthetic power generation.

[0115] In another embodiment, step S424 specifically includes, but is not limited to, the following steps:

[0116] S4241, when all the fuel cells of the second charging piles are in operation, set the switching device of the third charging pile to the second state;

[0117] S4242, when at least one fuel cell of a second charging pile is in standby mode, the product of the second quantity and the first output power is determined as the fifth output power, the fourth power difference between the second charging power and the fifth output power is determined, and the sixth quantity is determined based on the ratio of the fourth power difference to the third output power.

[0118] S4243, when the number of the sixth charging pile is greater than the number of the second charging piles in standby mode, the switching device of the third charging pile is set to the second state.

[0119] S4244, when the sixth number is less than or equal to the number of second charging piles in standby mode of fuel cells, the switching device of the third charging pile is set to the first state.

[0120] It should be noted that, as described in step S424 above, the second and fourth charging piles are two separate batches of photosynthetic charging piles. Under the conditions of step S424, the fourth charging pile will necessarily have all its photocatalytic power generation modules and fuel cells activated. However, the second charging pile may only have its photocatalytic power generation module activated or its fuel cell partially activated due to the lower demand from the first charging pile. When all the fuel cells in the photosynthetic charging piles are activated, the switching device of the third charging pile can be directly switched to the second state to introduce mains power.

[0121] It should be noted that in step S4242, the product of the second quantity and the first output power is the sum of the power provided by the fourth charging pile. Therefore, the fourth power difference is the power gap after the third charging pile introduces the fourth charging pile. The third output power is the output power of a single fuel cell. Therefore, the sixth quantity is the number of fuel cells that need to be introduced from the second charging pile.

[0122] It should be noted that in step S4243, if the sixth number is greater than the number of second charging piles in the standby state of the fuel cell, then even if all the fuel cells of the second charging piles are started, the fourth power difference cannot be met. The switching device of the third charging pile can be directly switched to the second state to introduce the mains power. Of course, all fuel cells can also be started in order to reduce the use of mains power.

[0123] It should be noted that in step S4244, the fuel cell of the second charging pile can meet the fourth power difference, switch the third charging pile to the first state, and start the fuel cells of multiple second charging piles according to the sixth quantity, so that the third charging pile can obtain sufficient power from the photosynthetic circuit network.
