[0001] This application is a divisional application. The original application has the application number 202211692428.8 and the original application date is December 28, 2022. The entire contents of the original application are incorporated herein by reference. Technical Field

[0002] This application relates to the field of energy technology, and in particular to an energy storage device, energy storage system, power station and charging network. Background Technology

[0003] With the continuous development and widespread application of clean energy, energy storage devices capable of storing electrical energy are increasingly used in various fields. In energy storage devices, multiple batteries connected in series and parallel are typically placed inside a casing to effectively protect them. During actual use, it is necessary to ensure the batteries are within a normal temperature range to guarantee their charging and discharging performance and safety. Furthermore, excessive humidity inside the casing can corrode some electronic components and even cause short circuits, thus compromising battery lifespan and safety. Summary of the Invention

[0004] This application provides an energy storage device, energy storage system, power station, and charging network capable of effectively regulating the temperature and humidity of a battery.

[0005] In a first aspect, this application provides an energy storage device, which may include a control device, a housing, and a battery located within the housing. The control device includes a first heat exchange plate, a radiator, a dehumidification assembly, and a valve assembly. The first heat exchange plate is disposed within the housing and in thermal contact with the battery for heat exchange, thereby heating or cooling the battery. The radiator is disposed outside the housing for heat exchange with the external environment. The dehumidification assembly includes a compressor, a condenser, a first throttling valve, and a first evaporator, which are sequentially circulated through pipelines. The first evaporator is located within the housing for condensing water vapor within the housing, and the condenser is located outside the housing. The valve assembly connects the first heat exchange plate and the radiator for opening or closing the passage between the first heat exchange plate and the radiator. In practical applications, the housing, the battery located within the housing, and the first heat exchange plate can form a single independent module. The radiator can be a standalone module. During deployment, the first heat exchange plate and the radiator can be connected via a valve body, allowing the medium to flow between them, thus improving deployment flexibility. Additionally, in the example provided in this application, a dehumidification component can be used to reduce humidity within the enclosure, enabling the battery to operate in a drier environment, which is beneficial for ensuring battery reliability and lifespan.

[0006] In one example, the valve body assembly can also be connected between the radiator and the condenser to connect or disconnect the passage between the radiator and the condenser. When the valve body assembly connects the passage between the radiator and the condenser, effective heat exchange can be carried out between the radiator and the condenser.

[0007] In one example, the control device may further include a humidity detector and a controller. The humidity detector is disposed inside the chamber to detect the humidity inside the chamber. The controller is communicatively connected to the humidity detector, the first throttling valve, and the compressor. The controller is used to control the first throttling valve and the compressor to open or close based on the detection signal from the humidity detector, thereby enabling automatic opening or closing of the dehumidification operation.

[0008] In one example, the control device may further include a second evaporator and a second throttling valve. The condenser, the second throttling valve, the second evaporator, and the compressor are sequentially connected via piping. The valve body assembly is also connected between the condenser and the first heat exchange plate, used to connect or disconnect the passage between the condenser and the first heat exchange plate. When the valve body assembly connects the passage between the condenser and the first heat exchange plate, effective heat exchange can occur between the condenser and the first heat exchange plate.

[0009] In one example, the valve body assembly can also be connected between the second evaporator and the first heat exchange plate to open or close the passage between the second evaporator and the first heat exchange plate. When the valve body assembly opens the passage between the second evaporator and the first heat exchange plate, effective heat exchange can occur between the second evaporator and the first heat exchange plate.

[0010] In one example, the control device may further include a second heat exchange plate and an energy storage converter, with the second heat exchange plate in thermal contact with the energy storage converter. The energy storage converter may be connected to the battery for controlling the charging or discharging of the battery.

[0011] In one example, the valve body assembly can also be connected between the second heat exchange plate and the first heat exchange plate to open or close the passage between the first heat exchange plate and the second heat exchange plate. When the valve body assembly opens the passage between the first heat exchange plate and the second heat exchange plate, effective heat exchange can be achieved between the first heat exchange plate and the second heat exchange plate.

[0012] In one example, the valve body assembly can also be connected between the second heat exchange plate and the radiator to open or close the passage between them. When the valve body assembly opens the passage between the second heat exchange plate and the radiator, effective heat exchange can be achieved between them.

[0013] In one example, the valve body assembly is also connected between the second heat exchange plate and the condenser, for connecting or disconnecting the passage between the second heat exchange plate and the condenser. When the valve body assembly connects the passage between the second heat exchange plate and the condenser, effective heat exchange can be achieved between the second heat exchange plate and the condenser.

[0014] In one example, the second heat exchange plate, the condenser, and the valve body assembly can be connected in series. That is, the second heat exchange plate and the condenser can be integrated in the same pipeline to facilitate docking with the valve body assembly, thus reducing the number of interfaces on the valve body assembly.

[0015] In one example, the control device may also include an electric heater for heating the medium flowing through the first heat exchange plate.

[0016] In specific configurations, the valve body assembly can contain one, two, or more valve bodies. Each valve body has multiple interfaces, and each interface can be connected to or disconnected from at least one of the other interfaces.

[0017] Secondly, this application also provides an energy storage system, which may include an inverter and the aforementioned energy storage device. The inverter is electrically connected to the battery and is used to convert alternating current (AC) into direct current (DC) to supply the battery, or to convert DC from the battery into AC. By applying the aforementioned energy storage device, the moisture resistance of the energy storage system can be effectively improved, and it has the advantages of high reliability and long service life.

[0018] Thirdly, this application also provides a power station, which may include a power generation device and the aforementioned energy storage device. The power generation device is electrically connected to a battery in the energy storage device, and the power generation device is used to store the generated electrical energy in the battery of the energy storage device. By applying the aforementioned energy storage device, the moisture resistance of the energy storage system can be effectively improved, and it has the advantages of high reliability and long service life.

[0019] Fourthly, this application also provides a charging network, which may include a charging pile and the aforementioned energy storage device. The charging pile is electrically connected to a battery in the energy storage device, and the battery is used to supply electrical energy to the charging pile. By applying the aforementioned energy storage device, the moisture resistance of the energy storage system can be effectively improved, and it has the advantages of high reliability and long service life.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0022] To facilitate understanding of the energy storage device provided in the embodiments of this application, its application scenarios will be introduced first below.

[0023] The energy storage device provided in this application embodiment can be applied in scenarios such as home energy storage, industrial energy storage, data centers, power stations and vehicle charging, for storing and releasing electrical energy.

[0024] like Figure 1 As shown, the energy storage device 10 may include a housing 12 and multiple batteries 13 disposed within the housing 12. The housing 12 provides sufficient space for the batteries 13, preventing them from being exposed to sunlight, rain, or other harmful substances, thereby improving the safety and lifespan of the batteries 13. Furthermore, placing the batteries 13 within the housing 12 also enhances the ease of deployment. In practical applications, the housing 12 can be positioned at the desired installation location according to actual deployment requirements.

[0025] During the charging and discharging process of battery 13, a significant amount of heat is generated, necessitating cooling. Currently, air cooling and liquid cooling are the two main methods used to cool battery 13. Air cooling relies primarily on airflow to remove heat from the surface of battery 13, resulting in low heat dissipation efficiency. Furthermore, dust accumulates on the surface of battery 13, causing corrosion and negatively impacting its reliability and lifespan. Liquid cooling, on the other hand, relies on a medium (such as water) flowing through cooling pipes to dissipate heat from battery 13, offering high heat dissipation efficiency. Consequently, more and more manufacturers are adopting liquid cooling for battery 13 cooling. However, with liquid cooling, moisture inside the casing 12 is difficult to expel. Prolonged moisture retention inside casing 12 can corrode battery 13 and related electronic components, potentially leading to short circuits and other malfunctions, affecting the safety and lifespan of the energy storage device 10. In some current energy storage devices 10, activated carbon or desiccant is usually placed inside the housing 12 to reduce the humidity inside the housing 12. However, this method is not conducive to long-term use and will increase the frequency of maintenance of the energy storage device 10 by the staff.

[0026] Therefore, this application provides an energy storage device 10 that can effectively regulate the temperature of the battery 13 and the humidity inside the housing 12.

[0027] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] The terminology used in the following embodiments is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” and “the” are intended to also include expressions such as “one or more,” unless the context clearly indicates otherwise. It should also be understood that in the following embodiments of this application, “at least one” means one, two, or more.

[0029] References to "one embodiment" and similar terms used in this specification mean that one or more embodiments of this application include a particular feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," and "in other embodiments" appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0030] like Figure 2 As shown, in one example provided in this application, the energy storage device 10 includes a housing 12, a battery 13 located inside the housing 12, and a control device 11. The control device 11 can effectively regulate the temperature of the battery 13 and reduce the humidity of the air inside the housing 12.

[0031] like Figure 3 As shown, the control device 11 may include a first heat exchange plate 111, a radiator 112, a dehumidification assembly 113, and a valve body 114. Specifically, the first heat exchange plate 111 is disposed inside the housing 12 and is in thermal contact with the battery 13 for heat exchange. The radiator 112 is disposed outside the housing 12 and can be used for heat exchange with the first heat exchange plate 111. In addition, the valve body 114 is connected between the first heat exchange plate 111 and the radiator 112, and is used to open or close the passage between the first heat exchange plate 111 and the radiator 112. When the valve body 114 opens the passage between the first heat exchange plate 111 and the radiator 112, the heat from the first heat exchange plate 111 can be transferred to the radiator 112 through the pipes, thereby effectively cooling the battery 13.

[0032] Alternatively, it can be understood that in practical applications, the housing 12, the battery 13 located within the housing 12, and the first heat exchange plate 111 can form an independent module. The radiator 112 can also be an independent module. During deployment, the first heat exchange plate 111 and the radiator 112 can be connected via the valve body 114, allowing the medium to flow between the first heat exchange plate 111 and the radiator 112, thus improving deployment flexibility.

[0033] In addition, in the example provided in this application, the humidity inside the cabinet 12 can also be reduced by the dehumidification component 113.

[0034] Specifically, the dehumidification assembly 113 may include a compressor 1134, a condenser 1131, a first throttle valve 1132, and a first evaporator 1133, which are connected sequentially through a circulation pipeline. The first evaporator 1133 is located inside the housing 12 and is used to condense the water vapor inside the housing 12. When the medium circulates in the passage formed by the compressor 1134, condenser 1131, first throttle valve 1132, and first evaporator 1133, the temperature of the first evaporator 1133 will be relatively low, thereby condensing the water vapor inside the housing 12 into water and reducing the humidity inside the housing 12.

[0035] In addition, since the temperature of the first evaporator 1133 is low, the temperature of the air inside the housing 12 can also be reduced, which helps to keep the battery 13 inside the housing 12 in a lower temperature environment.

[0036] Alternatively, it can be understood that in the energy storage device 10 provided in this application, the passage formed by the first heat exchange plate 111 and the radiator 112 can effectively reduce the surface temperature of the battery 13. Furthermore, the first evaporator 1133 in the dehumidification assembly 113 has a lower temperature, thus effectively reducing the temperature of the air inside the housing 12, thereby effectively improving the heat dissipation effect on the battery 13. Simultaneously, the first evaporator 1133 in the dehumidification assembly 113 can also condense water vapor inside the housing 12, thereby reducing the humidity of the air inside the housing 12, allowing the battery 13 to operate in a relatively dry environment, which is beneficial to ensuring the reliability and service life of the battery 13.

[0037] In a specific configuration, the energy storage device 10 may also include a humidity detector (not shown in the figure) and a controller (not shown in the figure). The humidity detector can be installed inside the housing 12 to detect the humidity inside the housing 12. The controller is communicatively connected to the humidity detector, the first throttle valve 1132, and the compressor 1134. The controller is used to control the opening or closing of the first throttle valve 1132 and the compressor 1134 based on the detection signal from the humidity detector. For example, when the humidity detector detects that the humidity inside the housing 12 is greater than a first preset value, it can generate a corresponding first detection signal. The controller can open the first throttle valve 1132 and the compressor 1134 based on this first detection signal to perform dehumidification. As the humidity inside the housing 12 gradually decreases, when the humidity detector detects that the humidity inside the housing 12 is less than a second preset value, it can generate a corresponding second detection signal. The controller can close the first throttle valve 1132 and the compressor 1134 based on this second detection signal to stop the dehumidification operation. It is understood that the first preset value refers to the threshold when the air humidity inside the cabinet 12 is high and dehumidification is required; the second preset value refers to the threshold when the air humidity inside the cabinet 12 is low and dehumidification is not required. In practical applications, the first and second preset values ​​can be set by the manufacturer before leaving the factory or set by the user, and this application does not impose any restrictions on this.

[0038] In addition, such as Figure 3 As shown, in a specific configuration, the valve body 114 can also be connected between the radiator 112 and the condenser 1131 to connect or disconnect the passage between the radiator 112 and the condenser 1131. When the dehumidification assembly 113 is performing dehumidification, the temperature of the condenser 1131 is relatively high. Therefore, in order to lower the temperature of the condenser 1131, the valve body 114 can be used to connect the condenser 1131 and the radiator 112, allowing the radiator 112 to cool the condenser 1131, thereby preventing the condenser 1131 from overheating.

[0039] In a specific configuration, a fan 118 can be placed near the heat sink 112. The fan 118 can be used to accelerate the airflow through the heat sink 112, thereby improving the heat dissipation performance of the heat sink 112. Of course, in other examples, the fan 118 can also be placed near the condenser 1131, and this application does not impose any restrictions on this.

[0040] In addition, in the example provided in this application, the control device 11 is also equipped with two water pumps, namely water pump 119a and water pump 119b. Water pump 119a is located at one end of the first heat exchange plate 111 and is used to accelerate the flow rate of the medium flowing through the first heat exchange plate 111, thereby improving the heat exchange efficiency of the first heat exchange plate 111. Water pump 119b is located at one end of the radiator 112 and is used to accelerate the flow rate of the medium flowing through the radiator 112, thereby improving the heat dissipation efficiency of the radiator 112. It is understood that in practical applications, the positions of water pumps 119a and 119b can be flexibly configured. For example, water pump 119a only needs to accelerate the flow rate of the medium flowing through the first heat exchange plate 111; water pump 119b only needs to accelerate the flow rate of the medium flowing through the radiator 112. This application does not limit the positions of water pumps 119a and 119b. Additionally, in some examples, when pump 119a and pump 119b are located in the same circulation path, one pump can be selectively removed to save on the number of pumps used, which will not be elaborated here.

[0041] In addition, such as Figure 4 As shown, in one example provided in this application, the control device 11 further includes a second evaporator 116 and a second throttle valve 115. The compressor 1134, condenser 1131, second throttle valve 115, and second evaporator 116 are sequentially connected via pipelines. A valve body 114 is also connected between the second evaporator 116 and the first heat exchange plate 111, used to connect or disconnect the passage between the second evaporator 116 and the first heat exchange plate 111. When the passage between the second evaporator 116 and the first heat exchange plate 111 is open, the second evaporator 116 can cool the first heat exchange plate 111, thereby improving the heat dissipation capacity of the battery 13.

[0042] Alternatively, it can be understood that in the example provided in this application, the combination of the second evaporator 116 and the second throttle valve 115 is connected in parallel with the combination of the first evaporator 1133 and the first throttle valve 1132, so that they do not affect each other. Specifically, during dehumidification, the first throttle valve 1132 can be opened and the second throttle valve 115 can be closed, allowing the refrigerant to circulate in the passage formed by the compressor 1134, condenser 1131, first throttle valve 1132, and first evaporator 1133, thereby ensuring that the first evaporator 1133 has a lower temperature to achieve the dehumidification function. Furthermore, the first throttle valve 1132 and the second throttle valve 115 can be opened simultaneously. That is, the refrigerant can circulate in the passage formed by the compressor 1134, condenser 1131, first throttle valve 1132, and first evaporator 1133, and can also circulate in the passage formed by the compressor 1134, condenser 1131, second throttle valve 115, and second evaporator 116. This allows both the first evaporator 1133 and the second evaporator 116 to have lower temperatures. Specifically, the first evaporator 1133 can perform dehumidification, while the second evaporator 116 can cool the battery 13 (first heat exchange plate 111). Alternatively, in a specific implementation, the second throttle valve 115 can be opened and the first throttle valve 1132 closed, allowing the refrigerant to circulate within the pathway consisting of the compressor 1134, condenser 1131, second throttle valve 115, and second evaporator 116. This results in the second evaporator 116 having a lower temperature, thus achieving the cooling function for the battery 13 (first heat exchange plate 111).

[0043] In summary, in the example provided in this application, the first evaporator 1133 and the second evaporator 116 in the control device 11 are decoupled from each other, which can avoid mutual influence between the two.

[0044] Furthermore, in the example provided in this application, the combination of the first evaporator 1133 and the first throttle valve 1132 shares the same condenser 1131 and compressor 1134 with the combination of the second evaporator 116 and the second throttle valve 115. This effectively reduces the number of components used, which is beneficial for reducing the size and cost of the adjustment device and facilitating integrated design. Of course, in other examples, the first evaporator 1133 and the second evaporator 116 can also be arranged in series, so that the first evaporator 1133 and the second evaporator 116 can share a single throttle valve. For example, only the first throttle valve 1132 or the second throttle valve 115 can be provided, thereby reducing the number of components used and helping to reduce manufacturing costs.

[0045] In addition, in the example provided in this application, the battery 13 can also be heated using the principle of a heat pump.

[0046] Specifically, such as Figure 4 As shown in the example provided in this application, the valve body 114 is also connected between the condenser 1131 and the first heat exchange plate 111, and is used to connect or disconnect the passage between the condenser 1131 and the first heat exchange plate 111. When the passage between the condenser 1131 and the first heat exchange plate 111 is connected, the heat in the condenser 1131 can be transferred to the first heat exchange plate 111 through the medium, thereby heating the battery 13.

[0047] In summary, in the example provided in this application, by effectively controlling the on and off states of different interfaces of the valve body 114, the access states of different modules can be flexibly adjusted, so as to make multi-faceted adjustments to the temperature of the battery 13.

[0048] In addition, such as Figure 5 As shown, in one example provided in this application, a second heat exchange plate 117 and an energy storage converter 14 are also included. The second heat exchange plate 117 is in thermal contact with the energy storage converter 14 for heat dissipation. The energy storage converter 14 is connected to the battery 13 and is used to control the charging or discharging function of the battery 13. Specifically, the energy storage converter can be a DC-AC converter or a DC-DC converter. That is, the energy storage converter 14 may include a DC-AC conversion device, or it may include a DC-DC conversion device, a control unit, etc. In specific applications, the specific type of energy storage converter 14 can be reasonably selected according to actual needs, and this application does not impose any restrictions on this.

[0049] like Figure 5 As shown, in specific applications, the valve body 114 can also be connected between the second heat exchange plate 117 and the first heat exchange plate 111 to connect or disconnect the passage between the first heat exchange plate 111 and the second heat exchange plate 117. Since the energy storage converter 14 generates heat during operation, when the temperature of the battery 13 is low, heat can be transferred to the surface of the battery 13 through the passage between the first heat exchange plate 111 and the second heat exchange plate 117, thereby making reasonable use of the waste heat generated by the energy storage converter 14 and achieving efficient heat utilization.

[0050] Additionally, the valve body 114 assembly can also be connected between the second heat exchange plate 117 and the radiator 112 to connect or disconnect the passage between the second heat exchange plate 117 and the radiator 112. In practical applications, when the energy storage converter 14 generates high levels of heat, the heat can be transferred to the radiator 112 through the passage between the second heat exchange plate 117 and the radiator 112, thereby improving the heat dissipation performance of the energy storage converter 14 and ensuring that the energy storage converter 14 remains within its normal operating temperature range.

[0051] Alternatively, in some examples, the valve body 114 assembly can also be connected between the second heat exchange plate 117 and the radiator 112 to open or close the passage between the second heat exchange plate 117 and the radiator 112. In practical applications, when the energy storage converter 14 generates high levels of heat, the heat can be transferred to the radiator 112 through the passage between the second heat exchange plate 117 and the radiator 112, thereby improving the heat dissipation performance of the energy storage converter 14 and ensuring that the energy storage converter 14 remains within its normal operating temperature range.

[0052] Or, such as Figure 5 As shown, in one example provided in this application, the control device 11 further includes an electric heater 15, which is used to heat the medium flowing through the first heat exchange plate 111, thereby increasing the temperature of the surface of the battery 13. In specific configurations, the location of the electric heater 15 can be varied. For example, as shown, the electric heater 15 can be connected in series at one end of the first heat exchange plate 111 or the second evaporator 116. Alternatively, in other examples, the electric heater 15 can be located in a separate pipeline, with both ends of the pipeline connected to the valve body 114, thereby enabling communication between the pipeline and the first heat exchange plate 111.

[0053] It should be noted that, in the example provided in this application, the valve body 114 is a ten-way valve, meaning that the valve body 114 has ten ports, and each port can be connected to or disconnected from at least one of the other ports. Alternatively, it can be understood that each port can be connected to or disconnected from any other port, and each port can be connected to at least two ports simultaneously.

[0054] In practical applications, the connection status of different interfaces in the valve body 114 can be effectively adjusted according to actual needs. For ease of understanding, each interface in the valve body 114 is distinguished by a label.

[0055] like Figure 6 As shown, in one example provided in this application, when the ambient temperature is high (such as in hot and humid summer conditions), the operating mode of the control device 11 is as follows: Specifically, in Figure 6 The diagram shows five loop paths.

[0056] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0057] In the second circulation path, the second evaporator 116 can be at a lower temperature, thereby cooling the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0058] In the third circulation path, the first heat exchange plate 111 can be cooled by the second evaporator 116. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 8, second evaporator 116, interface 3 and interface 4.

[0059] In the fourth circulation path, the second heat exchange plate 117 can be cooled by the radiator 112. The flow path of the medium is as follows: second heat exchange plate 117, interface 10, interface 2, water pump 119b, radiator 112, interface 7 and interface 9.

[0060] In the fifth circulation path, the condenser 1131 can be cooled by the radiator 112. The flow path of the medium is as follows: condenser 1131, interface 5, interface 2, water pump 119b, radiator 112, interface 7 and interface 6.

[0061] It should be noted that in the above example, the heater 15 is in the off state.

[0062] In other examples, the first heat exchange plate 111 can also be cooled by the radiator 112. For example, port 7 of valve body 114 can be connected to port 4, and port 1 can be connected to port 2. In this case, the medium flow path also includes: first heat exchange plate 111, water pump 119a, port 1, port 2, water pump 119b, radiator 112, port 7, and port 4. This allows the medium to circulate between the first heat exchange plate 111 and the radiator 112, thereby dissipating heat from the first heat exchange plate 111 through the radiator 112.

[0063] In addition, such as Figure 7 As shown, in another example provided in this application, when the ambient temperature is high (such as in hot and humid summer conditions), the operating mode of the control device 11 can also be as follows: Specifically, in Figure 7 The diagram shows four loop paths.

[0064] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0065] In the second circulation path, the second evaporator 116 can be at a lower temperature, thereby cooling the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0066] In the third circulation path, the first heat exchange plate 111 can be cooled by the second evaporator 116. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 8, second evaporator 116, interface 3 and interface 4.

[0067] In the fourth circulation path, the condenser 1131 and the second heat exchange plate 117 can be cooled by the radiator 112. The flow path of the medium is as follows: second heat exchange plate 117, port 10, port 2, water pump 119b, radiator 112, port 7, port 6, condenser 1131, port 5 and port 9.

[0068] In addition, such as Figure 8 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in low temperatures during winter) is as follows: Specifically, in Figure 8 The diagram illustrates a circulation path. The first heat exchange plate 111 (or battery 13) can be heated via the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 6, condenser 1131, interface 5, interface 9, second heat exchange plate 117, interface 10, and interface 4. The heat generated by the energy storage converter 14 can also be transferred to the first heat exchange plate 111 (or battery 13), thereby achieving efficient heat utilization. The electric heater 15 can be turned on or off as needed, which will not be described in detail here.

[0069] Additionally, it should be noted that in practical applications, both the second throttle valve 115 and the compressor 1134 can be set to the open state as needed. That is, through the working principle of the heat pump, the condenser 1131 can be made to have a higher temperature, thereby providing heat energy to the first heat exchange plate 111.

[0070] Or, such as Figure 9 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in the case of low temperature and high humidity in winter) is as follows: Specifically, in Figure 9 The diagram shows five loop paths.

[0071] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0072] In the second circulation path, the heat pump mode is activated. The condenser 1131 has a higher temperature, which can provide heat to the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0073] In the third circulation path, the first heat exchange plate 111 can be heated by the condenser 1131 and the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 6, condenser 1131, interface 5, interface 9, second heat exchange plate 117, interface 10 and interface 4.

[0074] In the fourth circulation path, the second evaporator 116 can be heated by the radiator 112. The medium flow path is as follows: second evaporator 116, interface 3, interface 2, water pump 119b, radiator 112, interface 7, interface 8. It can be understood that in heat pump mode, heat from the environment is transferred to the condenser 1131 through the second evaporator 116. Therefore, the temperature of the second evaporator 116 is relatively low. To dissipate the cooling capacity of the second evaporator 116, its temperature needs to be increased. This can be achieved by heating the second evaporator 116 with the electric heater 15, or by heat exchange between the radiator 112 and the second evaporator 116.

[0075] In addition, such as Figure 10 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in low temperatures during winter) is as follows: Specifically, in Figure 10 The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) can be heated by the electric heater 15 and the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump, interface 1, interface 8, electric heater 15, second evaporator 116, interface 8, interface 9, second heat exchange plate 117, interface 10 and interface 4.

[0076] It should be noted that at this time, the second throttle valve 115 is in the closed state; therefore, the temperature of the medium remains essentially unchanged as it flows through the second evaporator 116. Furthermore, in the example provided in this application, the electric heater 15 and the second evaporator 116 are connected in series in the same pipeline, which effectively reduces the number of ports on the valve body 114. Alternatively, it can be understood that if the electric heater 15 and the second evaporator 116 were each connected to the valve body 114 via separate pipelines, two more ports would be required in the valve body 114, thus increasing the total number of ports in the valve body 114.

[0077] In addition, such as Figure 11 As shown, in another example provided in this application, the operating mode of the control device 11 is as follows when the ambient temperature is suitable (such as in spring or autumn): Specifically, in Figure 11 The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) and the second heat exchange plate 117 (or energy storage converter 14) can dissipate heat through the radiator 112. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 2, water pump 119b, radiator 112, interface 7, interface 9, second heat exchange plate 117, interface 10, and interface 4.

[0078] In addition, such as Figure 12 As shown, in another example provided in this application, when the ambient temperature is suitable (such as in spring or autumn) and the humidity is high, the operating mode of the control device 11 is as follows: Specifically, in Figure 12 The diagram shows three loop paths.

[0079] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0080] In the second circulation path, the condenser 1131 can dissipate heat through the radiator 112. The flow path of the medium is as follows: condenser 1131, interface 5, interface 2, water pump 119b, radiator 112, interface 7, and interface 6.

[0081] In the third circulation path, the first heat exchange plate 111 (or battery 13) and the second heat exchange plate 117 (or energy storage converter 14) can dissipate heat through the radiator 112. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 2, water pump 119b, radiator 112, interface 7, interface 9, second heat exchange plate 117, interface 10 and interface 4.

[0082] In addition, such as Figure 13 As shown, in another example provided in this application, when the ambient temperature is suitable (such as in spring or autumn) and the humidity is high, the operating mode of the control device 11 is as follows: Specifically, in Figure 13 The diagram shows two loop paths.

[0083] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0084] In the second circulation path, the first heat exchange plate 111 (or battery 13), the second heat exchange plate 117 (or energy storage converter 14), and the condenser 1131 can dissipate heat through the radiator 112. The flow path of the medium is as follows: condenser 1131, interface 5, interface 9, second heat exchange plate 117, interface 10, interface 4, first heat exchange plate 111, water pump 119a, interface 1, interface 2, water pump 119b, radiator 112, interface 7, and interface 6.

[0085] It is understood that in the example provided in this application, the first heat exchange plate 111 and the water pump 119a are connected in series in the same pipeline, and this pipeline is connected through interface 1 and interface 4 of the valve body 114. Therefore, in practical applications, interface 1 can be connected to at least one other interface, and interface 4 can be connected to at least one other interface, thereby allowing for flexible selection of the flow path of the medium flowing through the first heat exchange plate 111.

[0086] In other examples, the water pump 119a and the first heat exchange plate 111 can also be connected to the valve body 114 using separate pipelines. Details will not be elaborated here. Furthermore, the connection configuration of different interfaces in the valve body 114 can be adjusted according to actual needs to form the required media flow path. Additionally, the valve body 114 can have more than ten interfaces to reserve interfaces for connection with other pipelines, which improves the versatility of the control device 11.

[0087] Additionally, in some examples, the number of interfaces in the valve body 114 can be appropriately reduced. That is, some components can be integrated in series.

[0088] For example, such as Figure 14As shown, in one example provided in this application, the second heat exchange plate 117 is connected in series with the condenser 1131 in the same pipeline, thereby saving two ports. That is, in the example provided in this application, the valve body 114 has eight ports, and each port can be connected to or disconnected from at least one of the other ports. Alternatively, it can be understood that each port can be connected to or disconnected from any other port, and each port can be connected to at least two ports simultaneously. It should be noted that in the example provided in this application, the second heat exchange plate 117 is located at the front end of the condenser 1131, so that the medium first flows through the second heat exchange plate 117 and then through the condenser 1131. Of course, in other examples, the second heat exchange plate 117 can also be located at the rear end of the condenser 1131, and this application does not limit this.

[0089] In practical applications, the connection status of different interfaces in valve body 114 can be effectively adjusted according to actual needs.

[0090] For example, such as Figure 14 As shown, in one example provided in this application, when the ambient temperature is high (such as in hot and humid summer conditions), the operating mode of the control device 11 is as follows: Specifically, in Figure 14 The diagram shows four loop paths.

[0091] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0092] In the second circulation path, the second evaporator 116 can be at a lower temperature, thereby cooling the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0093] In the third circulation path, the first heat exchange plate 111 can be cooled by the second evaporator 116. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 8, second evaporator 116, interface 3 and interface 4.

[0094] In the fourth circulation path, the second heat exchange plate 117 and the condenser 1131 can be cooled by the radiator 112. The flow path of the medium is as follows: condenser 1131, second heat exchange plate 117, interface 5, interface 2, water pump 119b, radiator 112, interface 7 and interface 6.

[0095] It should be noted that in the above example, the heater 15 is in the off state.

[0096] In other examples, the first heat exchange plate 111 can also be cooled by the radiator 112. For example, port 7 in the valve body 114 can be connected to port 4, and port 1 can be connected to port 2. In this case, the flow path of the medium also includes: first heat exchange plate 111, water pump, port 1, port 2, water pump, radiator 112, port 7, and port 4.

[0097] In addition, such as Figure 15 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in low temperatures during winter) is as follows: Specifically, in Figure 15 The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) can be heated by the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump, interface 1, interface 6, condenser 1131, second heat exchange plate 117, interface 5, interface 4, and electric heater.

[0098] It should be noted that in practical applications, both the second throttle valve 115 and the compressor 1134 can be set to the open state as needed. That is, through the working principle of the heat pump, the condenser 1131 can be kept at a higher temperature, thereby providing heat energy to the first heat exchange plate 111. Alternatively, the electric heater 15 can be turned on as needed to raise the temperature of the first heat exchange plate 111. Or, it can be understood that when the energy storage device 10 is deployed in a low-temperature area, the electric heater 15 can be installed as needed. Alternatively, when the energy storage device 10 is deployed in a high-temperature area, the electric heater 15 may not be required, thereby reducing deployment costs.

[0099] Or, such as Figure 16 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in the case of low temperature and high humidity in winter) is as follows: Specifically, in Figure 16 The diagram shows four loop paths.

[0100] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0101] In the second circulation path, the heat pump mode is activated. The condenser 1131 has a higher temperature, which can provide heat to the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0102] In the third circulation path, the first heat exchange plate 111 can be heated by the condenser 1131 and the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 6, condenser 1131, second heat exchange plate 117, interface 5 and interface 4.

[0103] In the fourth circulation path, the second evaporator 116 can be heated by the radiator 112. The medium flow path is as follows: second evaporator 116, interface 3, interface 2, water pump 119b, radiator 112, interface 7, and interface 8. It can be understood that in heat pump mode, heat from the environment is transferred to the condenser 1131 through the second evaporator 116. Therefore, the temperature of the second evaporator 116 is relatively low. To dissipate the cooling capacity of the second evaporator 116, its temperature needs to be increased. This increase in temperature can be achieved through heat exchange between the radiator 112 and the second evaporator 116.

[0104] In addition, such as Figure 17 As shown, in another example provided in this application, the operating mode of the control device 11 is as follows when the ambient temperature is suitable (such as in spring or autumn): Specifically, in Figure 17 The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) and the second heat exchange plate 117 (or energy storage converter 14) can dissipate heat through the radiator 112. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 6, condenser 1131, second heat exchange plate 117, interface 5, interface 2, water pump 119b, radiator 112, interface 7, and interface 4.

[0105] In addition, such as Figure 18 As shown, in another example provided in this application, when the ambient temperature is suitable (such as in spring or autumn) and the humidity is high, the operating mode of the control device 11 is as follows: Specifically, in Figure 18 The diagram shows three loop paths.

[0106] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0107] In the second circulation path, the first heat exchange plate 111, the second heat exchange plate 117, and the condenser 1131 can dissipate heat through the radiator 112. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 1, interface 6, condenser 1131, second heat exchange plate 117, interface 5, interface 2, water pump 119b, radiator 112, interface 7, and interface 4.

[0108] It is understandable that in the examples above, the control device 11 uses a single valve body 114. However, in other examples, the number of valve bodies 114 may be two, three, or more.

[0109] For example, such as Figures 19 to 24 As shown, this application also provides a control device including two valve bodies 114.

[0110] Specifically, such as Figure 19 As shown, the two valve bodies 114 are valve body 114a and valve body 114b. Both valve bodies 114a and 114b are four-way valves. That is, each valve body has four ports, and each port can be connected to or disconnected from at least one of the other ports. Alternatively, each port can be connected to or disconnected from any other port, and each port can be connected to at least two ports simultaneously. Alternatively, two four-way valves can be used instead of the aforementioned eight-way valve, thus providing greater flexibility.

[0111] In practical applications, the connection status of different interfaces in the valve body can be effectively adjusted according to actual needs.

[0112] For example, such as Figure 19 As shown, in one example provided in this application, when the ambient temperature is high (such as in hot and humid summer conditions), the operating mode of the control device 11 is as follows: Specifically, in Figure 19 The diagram shows four loop paths.

[0113] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0114] In the second circulation path, the second evaporator 116 can be at a lower temperature, thereby cooling the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0115] In the third circulation path, the first heat exchange plate 111 can be cooled by the second evaporator 116. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 3, interface 1, second evaporator 116, interface 5, and interface 6. The electric heater 15 is in the off state, thus not affecting the temperature of the medium.

[0116] In the fourth circulation path, the condenser 1131 and the second heat exchange plate 117 can be cooled by the radiator 112. The flow path of the medium is as follows: condenser 1131, second heat exchange plate 117, interface 8, interface 7, water pump 119b, radiator 112, interface 2 and interface 4.

[0117] In addition, such as Figure 20 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in low temperatures during winter) is as follows: Specifically, in Figure 20 The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) can be heated by the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 3, interface 4, condenser 1131, second heat exchange plate 117, interface 8 and interface 6.

[0118] It should be noted that in practical applications, both the second throttle valve 115 and the compressor 1134 can be set to the open state as needed. That is, through the working principle of the heat pump, the condenser 1131 can be made to have a higher temperature, thereby providing heat energy to the first heat exchange plate 111. In addition, the electric heater 15 can also be turned on as needed to increase the temperature of the first heat exchange plate 111.

[0119] Or, such as Figure 21 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in the case of low temperature and high humidity in winter) is as follows: Specifically, in Figure 21 The diagram shows four loop paths.

[0120] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0121] In the second circulation path, the heat pump mode is activated. The condenser 1131 has a higher temperature, which can provide heat to the first heat exchange plate 111 (or battery 13). The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, second expansion valve 115, and second evaporator 116.

[0122] In the third circulation path, the first heat exchange plate 111 can be heated by the condenser 1131 and the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 3, interface 4, condenser 1131, second heat exchange plate 117, interface 8 and interface 6.

[0123] In the fourth circulation path, the second evaporator 116 can be heated by the radiator 112. The medium flow path is as follows: second evaporator 116, interface 5, interface 7, water pump 119b, radiator 112, interface 2, and interface 1. It can be understood that in heat pump mode, heat from the environment is transferred to the condenser 1131 through the second evaporator 116. Therefore, the temperature of the second evaporator 116 is relatively low. To dissipate the cooling capacity of the second evaporator 116 and raise its temperature, heat exchange between the radiator 112 and the second evaporator 116 can be used to increase the heat output of the second evaporator 116.

[0124] In addition, such as Figure 22 As shown, in another example provided in this application, the operating mode of the control device 11 when the ambient temperature is low (such as in low temperatures during winter) is as follows: Specifically, in Figure 22 The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) can be heated by the electric heater 15 and the second heat exchange plate 117. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 3, interface 4, condenser 1131, second heat exchange plate 117, interface 8 and interface 6.

[0125] It should be noted that in practical applications, the second throttle valve 115 can be in the closed state, so the temperature of the medium will not change significantly when it flows through the second evaporator 116. Alternatively, the second throttle valve 115 and the compressor 1134 can be in the open state, thereby increasing the temperature of the condenser 1131 and enabling the condenser 1131 to heat the first heat exchange plate 111.

[0126] In addition, such as Figure 23 As shown, in another example provided in this application, the operating mode of the control device 11 is as follows when the ambient temperature is suitable (such as in spring or autumn): Specifically, in Figure 23The diagram shows a circulation path. The first heat exchange plate 111 (or battery 13) and the second heat exchange plate 117 (or energy storage converter 14) can dissipate heat through the radiator 112. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 3, interface 4, condenser 1131, second heat exchange plate 117, interface 8, interface 5, interface 1, interface 2, radiator 112, water pump 119b, interface 7, and interface 6.

[0127] In addition, such as Figure 24 As shown, in another example provided in this application, when the ambient temperature is suitable (such as in spring or autumn) and the humidity is high, the operating mode of the control device 11 is as follows: Specifically, in Figure 24 The diagram shows two loop paths.

[0128] In the first circulation path, the dehumidification component 113 can perform dehumidification. The flow path of the refrigerant is as follows: compressor 1134, condenser 1131, first expansion valve 1132, and first evaporator 1133.

[0129] In the second circulation path, the first heat exchange plate 111, the second heat exchange plate 117, and the condenser 1131 can dissipate heat through the radiator 112. The flow path of the medium is as follows: first heat exchange plate 111, water pump 119a, interface 3, interface 4, condenser 1131, second heat exchange plate 117, interface 8, interface 5, second evaporator 116, interface 1, interface 2, radiator 112, water pump 119b, interface 7, and interface 6.

[0130] It is understandable that in other examples, the control device 11 may also include three or more valve bodies, wherein the number of interfaces in each valve body can be any number of two or more, which will not be elaborated here. In addition, the docking of the interfaces in the valve body can be flexibly set according to actual needs to adjust the flow path of the medium.

[0131] In practical applications, Battery 13 can be used in scenarios such as home energy storage, industrial energy storage, data centers, and vehicles to store and release electrical energy.

[0132] For example, such as Figure 25 As shown in the illustration, this application also provides an energy storage system, which may include an inverter and a battery. The inverter is electrically connected to the battery and is used to convert alternating current (AC) into direct current (DC) to supply the battery, or to convert DC to AC from the battery.

[0133] In addition, the energy storage system may also include a battery management system, which can effectively detect parameters such as battery temperature, state of charge, and health status, and can also effectively regulate the charging and discharging function of the battery, thereby ensuring the normal operation of the energy storage device 10.
