[0050] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0051] The integrated energy system according to an embodiment of the present invention will now be described in detail with reference to the accompanying drawings.

[0052] like Figures 1 to 10 As shown, the integrated energy system according to an embodiment of the present invention includes a photovoltaic power generation system 10, an energy storage system 20, and an electricity consumption system 30.

[0053] First, the photovoltaic power generation system 10 will be described. The photovoltaic power generation system 10 includes a first port 13.

[0054] like Figure 1 and Figure 4 As shown, the photovoltaic power generation system 10 includes a first port 13 for connection to the battery cell 21 and the power consumption system 30. The photovoltaic power generation system 10 is capable of generating electricity under solar radiation. The photovoltaic power generation system 10 is known technology and will not be described further here.

[0055] Next, the power supply system 30 will be described. The power supply system 30 includes a fourth port 33.

[0056] like Figure 1 and Figure 6 As shown, the power system 30 includes a fourth port 33, through which it can be connected to the energy storage system 20 and the photovoltaic power generation system 10.

[0057] Specifically, the power system 30 includes one or more of the following: a data center, a monitoring device, and a lighting device.

[0058] like Figures 8 to 10 As shown, the power system 30 may include lighting devices, monitoring devices, data centers, etc. When there are multiple power systems 30, they can be connected in series or in parallel.

[0059] It should be noted that the above are just optional examples, and no specific limitations are made on the power system 30 here.

[0060] Next, the energy storage system 20 will be described. The energy storage system 20 includes a second port 23 and a third port 24. The energy storage system 20 includes battery cells 21 and a first control unit 22 that are electrically connected to each other. The first control unit 22 is used to control the photovoltaic power generation system 10 to charge the battery cells 21, and the photovoltaic power generation system 10 and battery cells 21 to supply power to the power consumption system 30. Specifically, the first port 13 is connected to the second port 23 via a first connecting line, and the first port 13 is connected to the fourth port 33 via a second connecting line; the third port 24 is connected to the fourth port 33 via a third connecting line.

[0061] like Figure 1 and Figure 2 As shown, the energy storage system 20 includes a second port 23 connected to the photovoltaic power generation system 10, and a third interface connected to the power consumption system 30. The battery unit 21 includes a battery unit 21 capable of storing electricity and a first control unit 22, which is electrically connected to the battery unit 21. The first control unit 22 is used to control the photovoltaic power generation system 10 to charge the battery unit 21, the photovoltaic power generation system 10 to supply power to the power consumption system 30, and the battery unit 21 to supply power to the power consumption system 30.

[0062] The first port 13 is connected to the second port 23 via the first connecting line, the first port 13 is connected to the fourth port 33 via the second connecting line, and the third port 24 is connected to the fourth port 33 via the third connecting line, thereby realizing the electrical connection between the photovoltaic power generation system 10, the energy storage system 20, and the power consumption system 30.

[0063] The above enables the photovoltaic power generation system 10 to provide power to the power consumption system 30 during the day when there is sufficient sunlight; during the day when there is insufficient sunlight, the photovoltaic power generation system 10 and the energy storage system 20 can jointly provide power to the power consumption system 30; and at night when there is no sunlight, the energy storage system 20 can provide power to the power consumption system 30. This allows the power consumption system 30 to operate continuously.

[0064] In the above integrated energy system, the first port 13 of the photovoltaic power generation system 10 is electrically connected to the second port 23 of the energy storage system 20 via a first connecting line. The first port 13 of the photovoltaic power generation system 10 is electrically connected to the power consumption system 30 via a second connecting line. The energy storage system 20 is electrically connected to the power consumption system 30 via a third connecting line. The energy storage system 20 includes a battery unit 21 capable of storing electricity and a first control unit 22. The first control unit 22 is used to control the photovoltaic power generation system 10, the battery unit 21, and the power consumption system 30, thereby enabling the photovoltaic power generation system 10 to charge the battery unit 21, the photovoltaic power generation system 10 to supply power to the power consumption system 30, and the battery unit 21 to supply power to the power consumption system 30. Therefore, even in off-grid conditions, this integrated energy system can provide power to the power consumption system 30 through the photovoltaic power generation system 10 and the battery unit 21, maintaining the long-term stable operation of the power consumption system 30.

[0065] In some embodiments of this utility model, the first connecting line and the third connecting line are both multi-functional connecting lines, which include a cable capable of transmitting power and a signal line capable of transmitting signals.

[0066] The first and third connecting lines use a multi-in-one connecting line, which can realize the transmission of signals and power, and is relatively simple.

[0067] In some embodiments of this invention, the battery cell 21 includes a plurality of sodium-ion cells.

[0068] Sodium-ion cells have a wide temperature range and can adapt to various environments. They can be used in low-temperature and extreme environments, making them suitable for the battery cell 21 of this invention.

[0069] In some embodiments of this utility model, the first control unit 22 includes a first monitoring device 221 and a signal receiving unit 222. The first monitoring device 221 is used to monitor the power status of the battery unit 21 and obtain power information. The signal receiving unit 222 is electrically connected to the first monitoring device 221 to receive the power information of the battery unit 21. The signal receiving unit 222 is also connected to the first port 13 through the second port 23 and the first connecting line to receive first information from the photovoltaic power generation system 10. The signal receiving unit 222 is also connected to the fourth port 33 through the third port 24 and the third connecting line to receive second information from the power consumption system 30.

[0070] like Figure 3 As shown, the first monitoring device monitors the power level of the battery unit 21, obtains power information, and sends this power information to the signal receiving unit 222. The signal receiving unit 222 also receives first information from the photovoltaic power generation system 10 and second information from the power consumption system 30.

[0071] Furthermore, the first control unit 22 also includes a central processing unit 223. The central processing unit 223 is electrically connected to the signal receiving unit 222. The central processing unit 223 is used to receive power information, first information, and second information from the signal receiving unit 222, and process them to generate a first control command for controlling the photovoltaic power generation system 10 and a second control command for controlling the battery unit 21. The central processing unit 223 is also electrically connected to the first port 13 through the second port 23 and the first connection line to send the first control command to the photovoltaic power generation system 10.

[0072] like Figure 3 As shown, the central processing unit 223 is the control core of the entire integrated energy system. It processes the power information from the battery unit 21, the first information from the photovoltaic power generation system 10, and the second information from the power consumption system 30 to generate a first control command for controlling the photovoltaic power generation system 10 and a second control command for controlling the battery unit 21. The first control command is then sent to the photovoltaic power generation system 10, thereby enabling the central processing unit 223 to easily control the battery unit 21 and the photovoltaic power generation system 10.

[0073] Furthermore, the first control unit 22 also includes a first execution device 224. The first execution device 224 is electrically connected to the central processing unit 223, and is used to receive and execute a second control command from the central processing unit.

[0074] For example, the central processing unit 223 issues a second control command to supply power to the power system 30, and the second control unit then controls the battery unit 21 to supply power to the power system 30. Thus, the battery unit 21 can easily supply power to the power system 30 when needed.

[0075] In some embodiments of this utility model, the photovoltaic power generation system 10 includes a power generation device 11 and a second control unit 12. The second control unit 12 is electrically connected to the power generation device 11.

[0076] like Figure 4 As shown, the power generation device 11 is electrically connected to the second control unit 12, and the second control unit 12 controls the power generation device 11.

[0077] Furthermore, the second control unit 12 includes a second monitoring device 121 and a second execution device 122. The second monitoring device 121 is used to monitor whether the power generation device 11 is in normal condition to obtain first information. The photovoltaic power generation system 10 is connected to the signal receiving unit 222 through the second monitoring device 121 to send the first information to the signal receiving unit 222. The second execution device 122 is electrically connected to the second monitoring device 121, and the photovoltaic power generation system 10 is electrically connected to the central processing unit 223 through the second execution device 122. The second execution device 122 receives and executes the first control command.

[0078] like Figure 5 As shown, the second control unit 12 includes a second monitoring device 121 and a second execution device 122 that are electrically connected to each other.

[0079] For example, the second monitoring device 121 monitors the status of the power generation device 11, obtains a first message indicating that the status is normal, and sends this first message to the signal receiving unit 222. The signal receiving unit 222 receives the power information of the battery unit 21 (the current power level is lower than the upper power threshold), and the central processing unit 223 combines the first message and the power information to issue a first control command to the second execution device 122 to charge the battery unit 21. The second execution device 122 executes this first control command, controlling the power generation device 11 to charge the battery unit 21.

[0080] Therefore, the photovoltaic power generation system 10 can easily charge the energy storage system 20 in a timely manner, and the photovoltaic power generation system 10 can easily supply power to the power consumption system 30.

[0081] In some embodiments of this utility model, the power system 30 includes a power-consuming device 31 and a third control unit 32. The third control unit 32 includes a third monitoring device 321 and a third execution device 322. The third monitoring device 321 is used to monitor the usage status of the power-consuming device 31 to obtain second information. The power system 30 is connected to a signal receiving unit 222 through the third monitoring device 321 to send the second information to the signal receiving unit 22. The third execution device 322 is used to control the power-consuming device 31.

[0082] like Figure 6 and Figure 7 As shown, the power system 30 includes a third monitoring device 321 and a third control unit 32 that are electrically connected to each other. The third control unit 32 includes the third monitoring device 321 and a third execution device 322 that are electrically connected to each other.

[0083] For example, the third monitoring device 321 detects that the electrical device 31 is in a state of demand and obtains second information based on this, and sends this second information to the signal receiving unit 222. The central processing unit 223 integrates the second information and the power information of the battery unit 21, and sends a second control command to the first execution device to supply power to the electrical system 30. The first execution device controls the battery unit 21 to supply power to the electrical system 30. The third execution device 322 controls the electrical device 31 to start and operate accordingly.

[0084] Therefore, the photovoltaic power generation system 10 and / or energy storage system 20 can supply power to the power consumption system 30 in a timely manner.
