It is understood that the energy station can also be located in cities or other regions; this is not a limitation.

[0039] In one embodiment, such as Figure 1As shown, an energy station is provided, including a photovoltaic module 10, multiple modular batteries 20, and a power conversion device 30. The photovoltaic module 10 is used for photovoltaic power generation, and the multiple modular batteries 20 are used for storing or releasing electrical energy. Each modular battery 20 is detachable. The power conversion device 30 connects the photovoltaic module 10, each modular battery 20, the power grid, and the load, and is used to convert energy between the photovoltaic module 10, each modular battery 20, the power grid, and the load. Using the photovoltaic module 10 to generate electricity provides clean energy and reduces the cost of electricity use. Using the power conversion device 30 for energy conversion, combined with the power grid, modular batteries 20, and load, a relatively simple structure can achieve the combined functions of power generation, energy storage, power distribution, and power consumption. The power quality is high. The multiple modular batteries 20 are detachable, and when electricity is needed, the modular batteries 20 can be directly removed to supply power to the load without waiting for the load to recharge, greatly shortening the recharge time, improving battery utilization efficiency, and enhancing the operational reliability of the energy station.

[0040] The photovoltaic module 10 is used for photovoltaic power generation. The photovoltaic module 10 converts solar energy into electrical energy, thereby reducing carbon emissions. Furthermore, using the photovoltaic module 10 as a substitute and supplement to grid electricity can also reduce electricity costs. The structure and quantity of the photovoltaic module 10 are not limited and can be configured according to actual needs.

[0041] The energy station comprises multiple modular batteries 20. A modular battery 20 refers to a battery system that is divided into multiple independent modules, each containing one or more battery cells. Each module is independent of the others, and each module can be regarded as a modular battery 20. The modular batteries 20 together form a complete battery system.

[0042] Each modular battery 20 can be detachably mounted on a battery base. Depending on usage, the modular battery 20 can be installed on or removed from the battery base for use within the energy station or outside the energy station. Alternatively, each modular battery 20 can be detachably mounted in other ways. The design of the modular battery 20 allows each battery module to be replaced individually without replacing the entire battery system, providing flexibility in use.

[0043] Modular battery 20 is used to store or release electrical energy. When installed within an energy station, modular battery 20 can be charged using electrical energy output from photovoltaic module 10 or the power grid to store energy, and can also discharge to connected loads or other devices to release energy. When installed outside the energy station, modular battery 20 can be used on loads to release energy to power the loads for normal operation. The specific type of modular battery 20 can be determined according to actual needs; for example, it can be a 1.5kWh modular storage battery, with its charging / discharging interface, anti-theft interface, and communication protocol using relatively common settings. Modular battery 20 also includes a control board, which can control the charging and discharging process of modular battery 20 and acquire relevant information about modular battery 20. Modular battery 20 and its control board can absorb photovoltaic power generation, store off-peak electricity, and provide batteries for loads such as battery-swapping agricultural machinery and vehicles.

[0044] The power conversion device 30 connects the photovoltaic module 10, each modular battery 20, the power grid, and the load, and is used to perform energy conversion between the photovoltaic module 10, each modular battery 20, the power grid, and the load. Specifically, the power conversion device 30 can convert the type of electrical energy, such as converting incoming direct current (DC) to alternating current (AC) before output, or converting incoming AC to DC before output. Furthermore, the power conversion device 30 can also convert the magnitude of electrical energy; in this case, the power conversion device 30 may not need to convert the type of electrical energy. Using an energy station structure as an example, the power conversion device 30 can convert the DC output from the photovoltaic module 10 to AC before output, or convert it to a specific magnitude of DC before output. The power conversion device 30 can also convert the AC output from the power grid to DC before output, or convert it to a specific magnitude of AC before output.

[0045] The structure of the power conversion device 30 is not limited; for example, it may include an inverter that can convert between AC and DC. It is understood that in other embodiments, the power conversion device 30 may also include other structures, which can be determined according to actual needs.

[0046] The load is the electrical equipment of the energy station. The type of load is not limited; for example, it can include DC loads and AC loads. Alternatively, the load can also include loads with replaceable batteries and loads with non-replaceable batteries. Loads with replaceable batteries are rechargeable / swappable loads; for example, loads with replaceable batteries can include agricultural tricycles, passenger vehicles, and agricultural machinery and implements. Loads with non-replaceable batteries can be smart appliances, such as flexible DC loads.

[0047] The aforementioned energy station includes photovoltaic modules 10, multiple modular batteries 20, and a power conversion device 30. The photovoltaic modules 10 generate electricity, and the modular batteries 20 store or release electrical energy. Each modular battery 20 is detachable. The power conversion device 30 connects the photovoltaic modules 10, the modular batteries 20, the power grid, and the load, and performs energy conversion between these components. Using photovoltaic modules 10 provides clean energy and reduces electricity usage costs. The power conversion device 30, combined with the power grid, modular batteries 20, and load, allows for a relatively simple structure that integrates power generation, energy storage, power distribution, and power consumption. The power quality is high. The detachable modular batteries 20 allow for direct power supply to the load when needed, eliminating the need to wait for the load to recharge, significantly reducing recharge time, improving battery utilization efficiency, and enhancing the reliability of the energy station.

[0048] In one exemplary embodiment, such as Figure 2 As shown, the power conversion device 30 includes a hybrid inverter 302 and a converter 304. The hybrid inverter 302 is connected to the photovoltaic module 10, each modular battery 20, the power grid and the first load, and is used to perform energy conversion between the photovoltaic module 10, each modular battery 20, the power grid and the first load. The converter 304 is connected to the hybrid inverter 302 and the second load, and is used to convert the power output from the hybrid inverter 302 and output it to the second load.

[0049] Among them, the hybrid inverter 302 is an inverter that integrates photovoltaic, mains power and battery power supply. It has the characteristics of both off-grid inverter and grid-connected inverter, and can flexibly switch between different power supply modes to make the power supply stable and reliable.

[0050] The hybrid inverter 302 connects the photovoltaic module 10, each modular battery 20, the power grid, and the first load, and is used to perform energy conversion between the photovoltaic module 10, each modular battery 20, the power grid, and the first load. Specifically, the hybrid inverter 302 can access the energy output from the photovoltaic module 10 and, through an algorithm, change the battery voltage of the photovoltaic module 10 to make the photovoltaic module 10 operate at its maximum power point, thereby increasing power generation. In addition, the hybrid inverter 302 can also connect to the 220V AC power from the power grid or a generator to supply power to the first load and the modular batteries 20, and control the charging and discharging of the modular batteries 20.

[0051] The first load is a load that can directly utilize the electrical energy output from the hybrid inverter 302, and its specific type is not limited. When the first load is a DC load, the hybrid inverter 302 can be connected to the DC load via a DC bus and output DC power to supply the DC load. Expandably, the hybrid inverter 302 can also output DC power to the modular battery 20 to power it. When the first load is an AC load, the hybrid inverter 302 can output AC power to supply the AC load. For example, the hybrid inverter 302 can output 48V DC and 220V AC power to supply the first load.

[0052] Converter 304 connects to hybrid inverter 302 and a second load, and is used to convert the electrical energy output from hybrid inverter 302 and output it to the second load. The type of converter 304 is not limited; for example, it can be an AC / DC converter 304, which converts the input AC power into DC power before outputting it. It is understood that in other embodiments, converter 304 can also be of other types, determined according to actual needs. The second load is a load that can operate using the electrical energy output from converter 304, and its specific type is not limited. Generally, the first load and the second load are different loads. It is understood that in some application scenarios, the first load and the second load can also include the same type of load to meet the power needs of diverse loads.

[0053] In this embodiment, the power conversion device 30 includes a hybrid inverter and a converter 304. The hybrid inverter connects the photovoltaic module 10, each modular battery 20, the power grid, and a first load, and is used to perform energy conversion between the photovoltaic module 10, each modular battery 20, the power grid, and the first load. The converter 304 connects the hybrid inverter and a second load, and is used to convert the electrical energy output from the hybrid inverter and output it to the second load. The hybrid inverter enables energy conversion between the photovoltaic module 10, each modular battery 20, the power grid, and the first load, achieving a composite function of power generation, energy storage, power distribution, and power consumption. Combined with the hybrid inverter and converter 304, power can be supplied to multiple loads, meeting the power needs of various loads and expanding the applicability of the energy station.

[0054] In one exemplary embodiment, the second load includes a first voltage load and a second voltage load, and the converter 304 includes a first converter 304 and a second converter 304. The first converter 304 is connected to the hybrid inverter and the first voltage load, and is used to convert the electrical energy output by the hybrid inverter and output a first voltage to the first voltage load. The second converter 304 is connected to the hybrid inverter and the second voltage load, and is used to convert the electrical energy output by the hybrid inverter and output a second voltage to the second voltage load.

[0055] The first voltage load is a load that operates based on a first voltage, and the second voltage load is a load that operates based on a second voltage. The first voltage and the second voltage are different.

[0056] The first converter 304 connects the hybrid inverter and the first voltage load, and is used to convert the electrical energy output from the hybrid inverter and output a first voltage to the first voltage load. The type of the first converter 304 is not limited; for example, it can be an AC / DC converter. Thus, the first converter 304 can convert the AC power output from the hybrid inverter 302 into a first voltage to supply power to the first voltage load.

[0057] The second converter 304 connects to the hybrid inverter and the second voltage load, and is used to convert the electrical energy output from the hybrid inverter into a second voltage output to the second voltage load. The type of the second converter 304 is not limited; for example, it can be an AC / DC converter 304. Thus, the second converter 304 can convert the AC power output from the hybrid inverter 302 into a second voltage to supply power to the second voltage load.

[0058] The specific values ​​of the first and second voltages can be set according to actual needs. The first voltage corresponds to the type of the first converter 304, and the second voltage corresponds to the type of the second converter 304. For example, if the first voltage is a 400V DC voltage and the second voltage is a 24V DC voltage, then the first converter 304 can be an AC220 / DC400 converter 304, and the second converter 304 can be an AC220 / DC24 converter 304. Correspondingly, the first voltage load is a load operating based on a 400V DC voltage, and the second voltage load is a load operating based on a 24V DC voltage, such as a temperature and humidity sensor installed in the power conversion device 30 cabinet.

[0059] In this embodiment, the second load includes a first voltage load and a second voltage load, and the converter 304 includes a first converter 304 and a second converter 304. The first converter 304 connects the hybrid inverter and the first voltage load, and is used to convert the electrical energy output from the hybrid inverter to output a first voltage to the first voltage load. The second converter 304 connects the hybrid inverter and the second voltage load, and is used to convert the electrical energy output from the hybrid inverter to output a second voltage to the second voltage load. Therefore, different first and second voltages can be output by the first converter 304 and the second converter 304 to supply power to the first voltage load and the second voltage load, enabling the energy station to supply power to different loads with various voltage requirements, thus improving the operating performance and usage flexibility of the energy station.

[0060] In one exemplary embodiment, the energy station further includes a first DC terminal block, through which the first converter 304 is connected to a first voltage load.

[0061] The first DC terminal block is an electrical component used to connect a DC power source and a load. It connects wires together through a mechanical structure, enabling stable current transmission. A first DC terminal block typically includes conductive and insulating components. The conductive components transmit electrical energy, while the insulating components provide isolation and protection, preventing short circuits or leakage.

[0062] The type of the first DC terminal is not unique. For example, it can be a threaded terminal, a crimped terminal, or a soldered terminal, which are suitable for different scenarios and are not limited here.

[0063] The first converter 304 is connected to the first voltage load via a first DC terminal, which ensures stable power transmission between the converter 304 and the load, reduces contact resistance and heat generation, and thus improves circuit stability and reliability. Furthermore, the first DC terminal makes the connection between the converter 304 and the load more modular, facilitating disassembly and maintenance. When a part needs to be replaced or repaired, the connection can be quickly disconnected, minimizing the impact on the entire energy station. In addition, the first DC terminal connection effectively reduces the risk of short circuits in exposed wires, reduces the occurrence of electrical accidents, and improves the overall safety of the energy station.

[0064] In this embodiment, the energy station also includes a first DC terminal block. The first converter 304 is connected to the first voltage load through the first DC terminal block, which facilitates disassembly and maintenance. It also enables stable power transmission between the first converter 304 and the first voltage load, improves the stability and reliability of the circuit, effectively reduces the short-circuit risk of exposed wires, reduces the occurrence of electrical accidents, and improves the overall safety of the energy station.

[0065] In one exemplary embodiment, the energy station further includes a first electricity meter connected to a first converter 304 and a first voltage load.

[0066] The first meter is connected to the first converter 304 and the first voltage load, and can be installed on the connection line between the first converter 304 and the first voltage load. The first meter can measure electrical energy data such as voltage, current, and power between the first converter 304 and the first voltage load.

[0067] Expandably, the first meter can also connect to other devices as needed to achieve corresponding functions. For example, the first meter can also connect to an interactive device. The first meter can transmit the measured data to the interactive device, allowing the interactive device to push the measurement data from the first meter to the user through information prompts, etc., so that the user can promptly understand the power supply status of the first converter 304 and the energization status of the first voltage load, etc., thus better enabling the monitoring of the energy station.

[0068] Alternatively, the first electricity meter can also be connected to devices with data processing capabilities, such as a controller. Taking the controller as an example, the controller can analyze and process the measurement data from the first electricity meter. When it determines that there is an abnormality in the power data between the first converter 304 and the first voltage load based on the measurement data, it can promptly send alarm information to the user through interactive devices, reminding the user to handle the abnormal situation in a timely manner and improve the working performance of the energy station.

[0069] In this embodiment, the energy station also includes a first meter, which is connected to the first converter 304 and the first voltage load. The first meter can measure electrical energy data such as voltage, current, and power between the first converter 304 and the first voltage load, which makes it convenient for users to monitor the working status of the first converter 304 and the first voltage load, and helps to improve the working performance of the energy station.

[0070] In one exemplary embodiment, the first load includes a DC load and an AC load, and the energy station also includes a second DC terminal and an AC terminal. The hybrid inverter is connected to the DC load through the second DC terminal and to the AC load through the AC terminal.

[0071] Among them, DC loads are loads that operate based on DC power, and AC loads are loads that operate based on AC power.

[0072] A second DC terminal block is an electrical component used to connect a DC power source and a load. It connects wires together through a mechanical structure, allowing for stable current transmission. A second DC terminal block typically includes conductive and insulating components. The conductive components transmit electrical energy, while the insulating components provide isolation and protection, preventing short circuits or leakage.

[0073] The type of the second DC terminal is not unique. For example, it can be a threaded terminal, a crimped terminal, or a soldered terminal, which are suitable for different scenarios and are not limited here.

[0074] The hybrid inverter connects to the DC load via a second DC terminal, ensuring stable power transfer between the inverter and the load, reducing contact resistance and heat generation, thereby improving circuit stability and reliability. Furthermore, the second DC terminal makes the connection between the hybrid inverter and the DC load more modular, facilitating disassembly and maintenance. When a component needs replacement or repair, the connection can be quickly disconnected, minimizing the impact on the entire energy station. In addition, the second DC terminal connection effectively reduces the risk of short circuits in exposed wires, decreasing the occurrence of electrical accidents and improving the overall safety of the energy station.

[0075] An AC terminal block is an accessory used to achieve electrical connections. The structure of an AC terminal block is not unique; for example, it may include an insulating component and a metal plate disposed within the insulating component. The metal plate has holes at both ends for inserting wires, which are then tightened or loosened using screws. Electrical connections can be achieved without complex soldering or winding operations.

[0076] The hybrid inverter connects to the AC load via AC terminals, facilitating the replacement of connected AC loads and making the removal and addition of wires quick and easy. It also improves the stability and reliability of the connection, thereby enhancing the stability of transmitted power.

[0077] In this embodiment, the first load includes a DC load and an AC load. The energy station also includes a second DC terminal and an AC terminal. The hybrid inverter connects to the DC load through the second DC terminal and to the AC load through the AC terminal. The second DC terminal and the AC terminal can improve the stability of the connection and are flexible to install and remove.

[0078] In one exemplary embodiment, the energy station also includes a current transformer connected to a hybrid inverter.

[0079] An instrument transformer is a type of power transformer that can transmit current or voltage and measure electrical energy. When an instrument transformer is connected to a hybrid inverter, the electrical energy input to or output by the hybrid inverter can be detected. The specific object to be detected depends on the connection location of the instrument transformer.

[0080] For example, the first end of the instrument transformer is connected to the AC grid port of the hybrid inverter, and the second end of the instrument transformer is connected to the CT port of the hybrid inverter. Thus, the instrument transformer can measure the amplitude and phase of the AC current in the AC grid and realize the monitoring of AC power.

[0081] In this embodiment, the energy station also includes a current transformer connected to the hybrid inverter. The current transformer can measure the electrical energy interacting with the hybrid inverter, which helps to improve the comprehensiveness of the energy station's status monitoring.

[0082] In one exemplary embodiment, the energy station also includes a second electricity meter connected to the hybrid inverter.

[0083] The second meter is connected to the hybrid inverter. This second meter can measure the inverter's voltage, current, power, and other electrical energy data.

[0084] Expandably, the second meter can also connect to other devices as needed to achieve corresponding functions. For example, the second meter can also connect to an interactive device. The second meter can transmit the measured data to the interactive device, allowing the interactive device to push the measurement data from the second meter to the user through information prompts, etc., so that the user can promptly understand the power status of the hybrid inverter and better monitor the energy station.

[0085] Alternatively, the second meter can also be connected to devices with data processing capabilities, such as controllers. Taking a controller as an example, the controller can analyze and process the measurement data from the second meter. If it determines that the output voltage of the hybrid inverter has not reached the target voltage based on the measurement data, it indicates that the hybrid inverter is malfunctioning. In this case, it can promptly send alarm information to the user through interactive devices, reminding the user to handle the abnormal situation in a timely manner and improve the working performance of the energy station.

[0086] In this embodiment, the energy station also includes a second electricity meter connected to the hybrid inverter. The second electricity meter can measure the electrical energy data related to the hybrid inverter, which facilitates the monitoring of the operating status of the hybrid inverter and helps to improve the working performance of the energy station.

[0087] In one exemplary embodiment, the energy station also includes an interactive device that connects the power conversion device 30 and each modular battery 20.

[0088] The interactive device is connected to the power conversion device 30 and can receive various information related to the power conversion device 30, such as energy information, setting parameters, and peak shaving and valley filling periods. After receiving this information, the interactive device can push it to the user through information prompts or other means.

[0089] The interactive device is also connected to each modular battery 20 and can receive information related to the modular batteries 20, such as battery identification information and power level information. After receiving this information, the interactive device can push this information to the user through information prompts or other means.

[0090] Depending on the structure of the interactive device, the way it provides information prompts also varies. For example, if the interactive device includes a display screen, the screen provides information prompts through text, charts, etc., offering diverse display styles and intuitive effects. If the interactive device includes a voice device, the voice device provides information prompts by broadcasting messages, which can be effective when the user is busy and is convenient to use. It is understood that in other embodiments, the interactive device can also have other structures, depending on actual needs.

[0091] Furthermore, the interactive device can also receive user commands so that the energy station can operate accordingly. For example, the interactive device can receive user commands that include peak and off-peak electricity consumption periods. Then, the power conversion device 30 can perform power conversion based on these user commands, enabling the energy station to stop or reduce its use of grid power during peak periods and increase its use of grid power during off-peak periods, thereby addressing the energy station's electricity costs. Alternatively, the interactive device can also receive user commands that control the locking or ejection of modular batteries 20. Then, the disassembly / removal structure in the modular batteries 20 controls the corresponding modular batteries 20 to lock or eject, facilitating the disassembly and reassembly of the modular batteries 20.

[0092] In this embodiment, the energy station also includes an interactive device that connects the power conversion device 30 and each modular battery 20. Through the interactive device, interaction can be achieved between the power conversion device 30, each modular battery 20, and the user, facilitating the user's monitoring and control of the energy station's operating status.

[0093] In one exemplary embodiment, the interaction device includes a gateway, a network switch, and an information interaction unit. The gateway is connected to the power conversion device 30 and each modular battery 20, the network switch is connected to the gateway, and the information interaction unit is connected to the network switch.

[0094] The network switch connects the gateway and the information exchange unit, acting as a relay station for information forwarding. The gateway can identify device communication addresses and forward information.

[0095] The gateway connects the power conversion device 30 and each modular battery 20, and can receive information from both the power conversion device 30 and each modular battery 20. For example, the gateway can transfer battery information from the modular batteries 20, enabling communication with batteries using special protocols. Furthermore, the gateway can also connect to and communicate with the power conversion device 30, and can read various information from the device, such as energy information and setting parameters like peak shaving and valley filling periods.

[0096] The gateway also connects to the network switch, allowing it to send data to and forward it. The information exchange unit connects to the network switch, receives data from the network switch, and pushes this data to the user through information prompts and other means.

[0097] The type of information interaction unit is not limited and can be set according to actual needs. For example, the information interaction unit can be a touch screen. Touch screens not only offer diverse display methods and can display a large amount of information, but they can also receive user commands, making them highly convenient to use.

[0098] Taking a touchscreen display as the information interaction unit, the touchscreen can display the electrical information of the energy station through a gateway and network switch, such as input voltage, current, and power; battery charging and discharging status and voltage; output voltage, current, and power; and can also control the locking and ejection of the modular battery 20. Furthermore, users can use the touchscreen to view whether the battery is in the energy station's battery compartment, its charging and discharging status and capacity, photovoltaic power generation, the interaction power between the energy station and the grid, load power, switch the energy station's grid-connected and off-grid operation status, and set operating parameters, offering a rich set of functions.

[0099] In a scalable manner, the gateway, network switch, and information interaction unit can be connected to the second converter 304, which can supply power to the gateway, network switch, and information interaction unit, thereby improving the energy utilization rate of the energy station.

[0100] In addition, the gateway can connect to the first and second electricity meters to collect electricity data. The gateway can communicate with the first and second electricity meters via CAN, which offers advantages such as good real-time performance, strong anti-interference capability, and high communication speed. The gateway can also connect to the temperature and humidity sensor installed in the power conversion device 30 to read temperature and humidity data. Using RS-485 communication between the gateway and the power conversion device 30 satisfies the requirement of half-duplex communication. Using RS-485 communication between the gateway and the temperature and humidity sensor reduces the computational power consumed by the gateway in parsing data and prevents the temperature and humidity sensor from consuming excessive data via CAN communication, thus limiting the gateway's resources.

[0101] In this embodiment, the interaction device includes a gateway, a network switch, and an information interaction unit. The gateway connects to the power conversion device 30 and each modular battery 20, the network switch connects to the gateway, and the information interaction unit connects to the network switch. Thus, the interaction device can monitor various data and issue various commands to control the operating status of the energy station, improving the ease of use of the energy station.

[0102] In one exemplary embodiment, the interaction device further includes a router connected to a network switch and communicating with a server.

[0103] The router connects to the network switch and communicates with it wirelessly, establishing a communication connection with the server. Data can then be transmitted through the gateway and network switch to the information interaction unit for information display, or uploaded to the cloud via the gateway, network switch, router, and server. Furthermore, the information interaction unit and the cloud can also issue commands to the gateway, which are then transmitted to other devices in the energy station, enabling control of the energy station.

[0104] In this embodiment, the interactive device also includes a router, which is connected to a network switch and communicates with the server. The router enables remote interaction between the energy station and the cloud, enriching the functionality of the energy station.

[0105] In one exemplary embodiment, such as Figure 1 As shown, the energy station also includes a storage battery 50, which is connected to the power conversion device 30. The storage battery 50 serves as a backup power source; when a grid failure occurs and power cannot be supplied, the storage battery 50 can be connected to the power conversion device 30 to supply power to the hybrid inverter, providing energy redundancy. The type of storage battery is not limited; for example, it can be a hydrogen fuel cell. Hydrogen fuel cells have high energy conversion efficiency, low carbon emissions, and wide applicability.

[0106] To better understand the above embodiments, a detailed explanation is provided below with reference to a specific embodiment. In one embodiment, as follows... Figure 1-2 As shown, the energy station includes photovoltaic modules 10, multiple modular batteries 20, a power conversion device 30, a first DC terminal block, a second DC terminal block, an AC terminal block, a first meter, a second meter, a transformer, an interaction device, and a storage battery. The power conversion device includes a hybrid inverter and a converter; the converter includes a first converter and a second converter; the interaction device includes a gateway, a network switch, an information interaction unit, and a router. The modular batteries include modular pluggable 1.5kWh batteries and their control board ②. The router is a 4G router ④, and the gateway is a 3G gateway ⑥. The first converter is an AC220 / DC400 converter ⑦, and the second converter is an AC220 / DC24 converter ⑧. Both the first and second meters are ET / QT DC meters ⑨. The first DC terminal block is a 400V DC quick-connect terminal. The second DC terminal is a 48V DC quick-connect terminal⑩, and the AC terminal is a 220V AC quick-connect terminal. The information interaction unit is a 12-inch touch screen. Figure 3 This is a 3D diagram of the energy station. The dimensions in the diagram are for illustrative purposes only, but other dimensions can also be used. The unit of measurement can be meters.

[0107] In terms of electrical connections, the hybrid inverter ① outputs 48V DC power to supply the modular, pluggable 1.5kWh battery and its control board ②, as well as the 48V DC load. The hybrid inverter ① outputs 220V AC power, which is then converted to 400V DC power by the AC220 / DC400 converter ⑦ to power the 400V DC load. The 220V AC power is further converted to 24V DC power by the AC220 / DC24 converter ⑧ to provide 24V power to the 12-inch touchscreen display ③, the 4G router ④, the network switch ⑤, and the 3G gateway ⑥.

[0108] In terms of communication connections, the AC grid port of the hybrid inverter ① is connected to the CT port via a current transformer. The current transformer's main function is to measure the amplitude and phase of the AC current in the AC grid. The CAN port of the hybrid inverter ① is interconnected with the CAN ports of eight modular pluggable 1.5kWh batteries and their control boards ② and the third-generation gateway ⑥, used to receive battery BMS information translated by the gateway and achieve communication with the batteries using this special protocol. The COM1 port of the hybrid inverter ① is connected to the 485_1 port of the third-generation gateway ⑥ for communication, allowing the reading of various information from the hybrid inverter ①, such as energy information and setting parameters like peak shaving and valley filling time information. The 12-inch touch screen ③, 4G router ④, and third-generation gateway ⑥ are all connected to the network switch ⑤ and communicate with each other. Data can be uploaded from the third-generation gateway ⑥ to the 12-inch touch screen ③ and the cloud, or commands can be sent from the 12-inch touch screen ③ and the cloud to the third-generation gateway ⑥.

[0109] The 48V DC bus and the DC 400V DC bus are connected to the CAN1 and CAN2 ports of the third-generation gateway ⑥ via two ET / QT meters ⑨ to collect power data. The temperature and humidity sensor inside the cabinet is connected to the 485_2 port of the third-generation gateway ⑥ to read temperature and humidity data.

[0110] The BMS and the electricity meter use CAN communication, which has the advantages of good real-time performance, strong anti-interference ability, and high communication speed. The gateway and the hybrid inverter use 485 communication, which requires master-slave half-duplex communication between the two. The gateway and the temperature and humidity sensor use 485 communication, which can reduce the computing power consumption of the gateway in parsing data and prevent the temperature and humidity sensor from consuming a lot of data from CAN communication and consuming gateway resources.

[0111] Specifically, the main function of the hybrid inverter is to absorb the electrical energy generated by photovoltaic modules with a power output of 5-9 kWp, and to change the voltage of the photovoltaic cells through algorithms to make them operate at their maximum power point, thereby increasing power generation. The hybrid inverter can also connect to the grid or generator's 220V AC power, outputting 220V AC and 48V DC power to supply loads and batteries, and controlling the charging and discharging of the batteries. The main function of the modular pluggable 1.5kWh battery and its control board ② is to absorb photovoltaic power generation, store off-peak electricity, and provide batteries for battery-swapping agricultural machinery and vehicles; the control board's main function is to charge the batteries. The main function of the 12-inch touch screen ③ is to display the electrical information of the micro-energy station, such as input voltage, current, power, battery charging and discharging status and voltage, output voltage, current, and power, and to control the locking and ejection of the batteries. The main function of the 4G router ④ is to conduct wireless communication with the server. The main function of the network switch ⑤ is to act as a connection relay station between the 12-inch touch screen ③, the 4G router ④, and the 3G gateway ⑥, forwarding information. The main function of the third-generation gateway (⑥) is to identify device communication addresses and forward information. The main function of the AC220 / DC400 converter (⑦) is to convert 220V AC to 400V DC. The main function of the AC220 / DC24 converter (⑧) is to convert 220V AC to 24V DC. The main function of the ET / QT meter (⑨) is to measure DC voltage, current, power, and other electrical energy data.

[0112] This energy station utilizes a photovoltaic-storage-DC-flexible technology, allowing it to connect to photovoltaic power generation. It employs a DC bus architecture, outputting 400V and 48V DC power and inputting or outputting 220V AC power. Furthermore, the station can charge and discharge modular pluggable batteries, using standardized 1.5kWh modular batteries instead of larger storage batteries. These batteries have multiple uses: they can supplement the power of agricultural machinery and implements, store excess photovoltaic power, reduce peak-to-valley differences during grid load fluctuations to generate revenue, and release energy to improve power quality when grid supply is under pressure. The energy station also allows users to monitor battery status, charging / discharging status, capacity, photovoltaic power generation, grid interaction power, load power, switch between grid-connected and off-grid operation, and set operating parameters via a touchscreen display.

[0113] By adopting the 1.5kWh standardized modular battery of this application, which can be used to improve power quality in rural power grids and also applied to agricultural machinery and implements, the utilization efficiency of the battery is improved by 20%. Agricultural machinery and implements do not need to be charged, which significantly reduces the recharging time by 80%. The use of photovoltaic power generation can significantly reduce grid electricity costs by 60% and reduce carbon emissions. By adopting a peak-valley arbitrage strategy combined with the battery, an additional 20% electricity cost revenue can be obtained. Discharging during peak load periods can provide standard industrial frequency AC power, improving the power quality of rural power grids.
