Description

Technical Field

[0001] The present application relates to the technical field of containerized energy storage systems, and in particular to an energy storage container and an energy storage container system. Background Art

[0002] The energy storage industry has become a crucial component of my country's strategic emerging industries. The large-scale integration of renewable energy into the grid presents challenges in balancing electricity supply and demand over varying timescales. New energy storage technologies not only promote the large-scale, high-quality development of renewable energy and contribute to achieving the "dual carbon" goals, but also, as a core technology and strategically important area of ​​the energy revolution, are expected to form a new industry with high technological content and significant growth potential, becoming a new economic driver. Energy storage battery prefabricated cabins, as systems capable of storing high amounts of energy and performing rapid charging and discharging, have been widely adopted within the energy storage industry.

[0003] In the energy sector, containerized energy storage systems are an innovative energy storage solution. By integrating batteries, control equipment, and cooling systems into a standard container, they provide an efficient, reliable, and flexible energy management solution for power grids, industrial, and commercial markets. The advantages of this system are reflected in multiple aspects: rapid deployment and modular design, high flexibility and versatility, cost-effectiveness and economy, environmental friendliness and sustainability, safety and reliability, easy maintenance, and long life. Containerized energy storage systems, with their rapid deployment, high flexibility, cost-effectiveness, environmental friendliness, safety and reliability, and easy maintenance, are gradually becoming a vital component of modern energy management. With continuous technological advancement and market expansion, containerized energy storage systems will play an even more important role in the future energy landscape.

[0004] As the capacity of battery cells within energy storage containers increases, the requirements for thermal management, thermal runaway control, and structural strength control are becoming increasingly stringent. In existing energy storage containers, the air conditioning fan and compressor that blow air to the outside of the container are both located on one side of the container, which brings many problems: 1. Due to the small side area of ​​the container, the fan and compressor are both located on one side, which makes it impossible to use larger fans or install multiple compressors. This affects the cooling capacity of the energy storage container, resulting in inaccurate temperature control of the battery cells, which cannot effectively ensure the efficiency and lifespan of the battery cells. 2. The fan is located on the side of the container, and the fan size is small. To achieve the expected cooling capacity, the fan speed must be increased, resulting in loud side noise from the air conditioning. 3. Due to the large-scale integration of energy storage containers in the terminal, when the energy storage containers are placed side by side, the air inlet and outlet components on the side of the container will interfere with each other. For example, the hot air discharged from one energy storage container will be sucked into another energy storage container, reducing the cooling capacity of the energy storage container that has sucked in the hot air. Therefore, when existing energy storage containers are placed side by side, they must be separated by a certain distance, which increases the floor space occupied by the energy storage containers in the terminal. In addition, energy storage containers all discharge hot air from the sides. Under the dense and centralized layout of energy storage containers, hot air accumulates in the station, forming a heat island in the station, making the temperature in the station much higher than the ambient temperature, increasing the risk of overheating of energy storage container equipment. Summary of the Invention

[0005] The embodiments of the present application provide an energy storage container and an energy storage container system to solve the problem caused by the existing energy storage containers in which the air conditioning fan and the air conditioning compressor for blowing air to the outside of the container are both arranged on one side of the container.

[0006] In a first aspect, an embodiment of the present application provides an energy storage container, comprising:

[0007] A box body and a heat pump system, wherein the box body has a storage space, a battery compartment is provided in the storage space, a plurality of battery cells are provided in the battery compartment, and the heat pump system is used to regulate the temperature of the battery cells;

[0008] Within the accommodating space, the top space above the battery compartment is provided with a heat exchange component of the heat pump system, the heat exchange component includes a fan and a heat exchanger, the heat exchange component is used to exchange heat between the refrigerant in the heat exchanger and the air outside the box, the fan discharges air to the outside of the box, and the compressor of the heat pump system is arranged on the outer side of the box.

[0009] In a possible design, the heat pump system further includes an air inlet, which is disposed at the top of the box.

[0010] In a possible design, the heat pump system further includes an air inlet baffle, which is arranged at the air inlet.

[0011] In a possible design, a plurality of the heat pump systems are included, and the compressors of the plurality of heat pump systems are all arranged on the outer side of the box.

[0012] In a possible design, it further includes a power conversion system disposed in the accommodation space, the power conversion system being used to convert the direct current output by the battery cell into alternating current, or to convert alternating current into direct current and input it into the battery cell;

[0013] Among the multiple heat pump systems, at least one heat pump system is used to regulate the temperature of the battery core inside the battery compartment, and at least one heat pump system is used to regulate the temperature of the power conversion system.

[0014] In a possible design, a partition beam is provided in the top space, and the heat exchange assembly is installed above the partition beam.

[0015] In a possible design, a fire-fighting system is further included, and the fire-fighting system is installed below the dividing beam.

[0016] In a possible design, the partition beam includes a first beam frame and a second beam frame, the first beam frame and the second beam frame are both connected to the box body, and the first beam frame is located above the second beam frame;

[0017] The heat exchange assembly is installed above the second beam, and the fire protection system is installed below the first beam.

[0018] In a possible design, the partition beam further includes a main beam, and both ends of the main beam are respectively connected to the box body;

[0019] The first beam frame and the second beam frame are respectively connected to the main beam.

[0020] In a second aspect, an embodiment of the present application provides an energy storage container system, comprising a plurality of the energy storage containers described in the first aspect, wherein the plurality of energy storage containers are arranged side by side.

[0021] The energy storage container and energy storage container system provided in the embodiments of the present application utilize the space at the top of the battery compartment efficiently because the fan is placed on the top of the energy storage container. Due to the large area of ​​the container top, a larger fan can be placed on the top. Under the same heat dissipation conditions, the large fan has a lower speed, effectively reducing the noise during heat pump operation. Compared with the prior art design in which both the fan and compressor are located on one side of the container, since the fan is no longer located on the side of the container, the free space can be used to install a larger and more powerful compressor, or to install multiple compressors, thereby improving the temperature regulation capacity of the energy storage container. This allows the installation of more battery cells in the energy storage container, while also providing more precise temperature control for the battery cells, ensuring the efficiency and lifespan of the battery cells. At the same time, because the fan is located on the top of the box, when the energy storage containers are arranged side by side in the terminal, the hot air discharged from the energy storage containers will not circulate. This allows the energy storage containers to be placed more compactly, reducing the floor space occupied by the energy storage containers in the terminal. BRIEF DESCRIPTION OF THE DRAWINGS

These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0048] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

[0049] First, let’s explain the terms that appear in this application:

[0050] A heat pump is an energy conversion device whose primary function is to transfer heat from one location to another. It can be used for both heating and cooling and is widely used in homes, businesses, and industrial settings. Based on the reverse Carnot cycle, a heat pump transfers heat from a low-temperature heat source to a high-temperature heat source while consuming a small amount of electrical energy. A heat pump primarily consists of a heat exchanger, which includes an evaporator and condenser, a compressor, and an expansion valve. In energy storage containers, heat pumps primarily regulate the temperature of the battery cells within the battery compartment.

[0051] Battery compartment: The part of the energy storage container specifically used to store battery modules.

[0052] Battery cell: The basic unit of the energy storage system in the energy storage container. The main types include lithium-ion batteries, lithium iron phosphate batteries, lithium titanate batteries, lead-acid batteries, etc.

[0053] PCS system: The PCS system in the energy storage container is a key component of the entire energy storage system. The PCS system is responsible for converting and managing electrical energy, enabling the energy storage system to efficiently exchange energy with the grid and other power loads. Its main functions include DC / AC conversion, power management, and energy flow control.

[0054] The figure shows a side view of an existing energy storage container. As shown, the upper left side of the existing energy storage container houses the air conditioning fan, the lower left side houses the air conditioning compressor, and the right side houses the electrical control equipment. During air conditioning operation, the fan shown in the figure primarily serves to increase the temperature difference between the air conditioning heat exchanger and the outside air, improving the heat exchange efficiency of the heat exchanger and effectively dissipating heat from the air conditioner. Since the fan and compressor are both squeezed into one side of the container, this presents several problems: Due to the small side area of ​​the container, the placement of both the fan and compressor on one side precludes the use of larger fans and the installation of multiple compressors, which impacts the cooling capacity of the energy storage container. The fan, being located on the side of the container, is relatively small, requiring a higher fan speed to achieve the desired cooling capacity, resulting in higher side noise during air conditioning operation. Furthermore, since energy storage containers are often integrated and used on a large scale within a terminal, when placed side by side, the air inlet and outlet components on the sides of the containers interfere with each other. For example, hot air discharged from one container can be drawn into another, reducing the cooling capacity of the container drawing in the hot air. Therefore, existing energy storage containers must be placed a certain distance apart when placed side by side, which increases the floor space occupied by the energy storage containers in the station.

[0055] Furthermore, due to the energy conversion losses during storage and release within the energy storage container, much of the energy is converted into heat. Air conditioning systems release this heat into the station environment through fans. If the fans in the energy storage containers exhaust hot air from the sides, the densely packed layout of the energy storage containers will cause heat to accumulate and become undispersed within the station, creating a heat island within the station, causing the temperature inside the station to be significantly higher than the ambient temperature. For example, reliable data shows that in a large 100MW / 200MWh station with an ambient temperature of 43°C, using existing energy storage container designs, the ambient temperature in the living area is 46°C, while the ambient temperature inside the power station is as high as 53.3°C. Because large-scale energy storage container systems are connected to the power grid, high temperatures within the station increase the risk of equipment overheating, potentially leading to derating and downtime, impacting grid scheduling, and ultimately causing uneven grid load and power shortages in some areas. Furthermore, high temperatures increase the auxiliary power consumption of the energy storage container refrigeration units, accelerate chemical reactions within the batteries, and accelerate the aging of core equipment such as batteries, converters, and box-type transformers, resulting in a chain reaction of reduced efficiency.

[0056] In response to the above problems, considering that there is still a certain space between the battery compartment and the top plate of the existing energy storage container, the top space above the battery compartment is only used to install the fire protection system, and a large amount of top space is wasted. Therefore, the technical concept of this application is to place the heat exchange component of the heat pump in the top space above the battery compartment inside the energy storage container. The heat exchange component includes a fan that discharges air to the outside of the box and a corresponding heat exchanger, and the compressor of the heat pump is placed on the side outside the box.

[0057] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0058] Example 1

[0059] This embodiment provides an energy storage container. Figure 2 Schematic diagram of the energy storage container structure provided in the embodiment of this application Figure 1 , Figure 2 The figure shows the energy storage container's housing 100 and the heat exchange assembly 300 of the heat pump system. Housing 100 has a storage space 110, within which is located a battery compartment 200. Battery compartment 200 houses multiple battery cells. In this embodiment, the battery compartment 200 is divided into the following levels, from largest to smallest: battery cluster level, battery pack level, module level, and battery cell level. In this embodiment, the heat pump system can regulate the battery cell temperature through air cooling or liquid cooling.

[0060] Figure 2 In the storage space 110, the top space above the battery compartment 200 is provided with a heat exchange assembly 300 of the heat pump system. The heat exchange assembly 300 includes a fan 320 and a heat exchanger. The heat exchanger is used to exchange heat with the air outside the box 100, and the fan 320 discharges air to the outside of the box 100. Since the heat pump system in the energy storage container usually functions to regulate the temperature of the battery core by cooling, the heat exchanger in the heat exchange assembly 300 in the top space is usually a condenser. The refrigerant in the heat pump system pipeline needs to condense and release heat in the condenser. The fan 320 can increase air flow by rotating, speeding up the condensation speed of the condenser, allowing the refrigerant to complete the phase change process more quickly and dissipate heat to the outside of the box 100. Therefore, the fan 320 discharges air to the outside of the box 100. When the heat pump system needs to regulate the temperature of the battery core by heating, especially in a low temperature environment, the heat exchanger is an evaporator. To improve heat exchange efficiency, the fan 320 usually still discharges air to the outside of the box 100.

[0061] In this embodiment, the frame of the box body 100 can be welded together by supporting parts such as the bottom beam, top beam, column, top plate, bottom plate, battery pack bracket, etc., and the outer shell of the box body 100 can include protective parts such as the battery compartment 200 door, the electrical room 00 door, and the rear wall panel.

[0062] The heat exchange assembly 300 can be installed in the top space in a variety of ways. For example, the support structure for installing the heat exchange assembly 300 can be bolted to the top beam of the box body 100, so that the heat exchange assembly 300 is hoisted to the top beam; or a support structure is set in the accommodating space 110 along the length of the box body 100, and the heat exchange assembly 300 is installed above the support structure; or the support structure for installing the heat exchange assembly 300 is connected to the side wall or column of the box body 100. The above examples illustrate that there are multiple implementation methods for arranging the heat exchange assembly 300 in the top space in this application.

[0063] Figure 3 This is a side view of the energy storage container provided in the embodiment of the present application. Figure 3 The heat pump system is shown in the figure, wherein the compressor 330 is located on the outer side of the box 100, and the electrical room 00 next to the compressor 330. In the embodiment of the present application, the electrical room 00 can include all control parts of the energy storage container, the DC side or AC side bus output, and the fire gas cylinder.

[0064] Figure 4 This is a schematic diagram of the exterior of an energy storage container provided in an embodiment of the present application, showing multiple fans 320 on the top of the container 100 and multiple compressors 330 on the external side of the container 100.

[0065] The existing technology Figure 1 and the embodiments of this application Figure 2 、 Figure 3 、 Figure 4 After comparison, it can be seen that after the heat exchange component 300 of the heat pump system is placed in the top space of the box 100, the space on the side of the box 100 where the fan 320 was originally placed is freed up. The free space allows a larger and more powerful compressor 330 to be installed on the side of the box 100, or multiple compressors 330 of the heat pump system to be installed as shown in the figure. For example, the existing energy storage container can only install one 60kw cooling capacity heat pump unit, while in the embodiment of the present application, two 60kw cooling capacity heat pump units can be installed, and the compressors 330 of the two heat pump units are both located on the outer side of the box 100. In this way, the temperature regulation capacity of the energy storage container can be improved, more battery cells can be installed, and the battery cell temperature can be controlled more accurately, thereby ensuring the efficiency and life of the battery cells.

[0066] When multiple heat pump systems are provided, the compressors 330 of the multiple heat pump systems are all provided on the outer side of the box body 100. In this case, a liquid-cooled PCS system, i.e., a liquid-cooled power conversion system, can be installed in the internal accommodation space 110 of the box body 100. In this embodiment, the power conversion system is at least used to convert the DC power output by the battery cell into AC power, or to convert the AC power into DC power and input it into the battery cell.

[0067] Among the multiple heat pump systems, at least one heat pump system is used to regulate the temperature of the battery cells inside the battery compartment 200 , and at least one heat pump system is used to regulate the temperature of the power conversion system.

[0068] In the prior art, due to the limited side space of energy storage containers, only a single heat pump system can be installed. This single heat pump system can only meet the temperature regulation requirements of the battery cells, and it is impossible to install a liquid-cooled PCS system inside the box 100. In this embodiment, after the fan 320 is placed on the top, the remaining space can be used to install compressors 330 of multiple heat pump systems. Some heat pump systems can regulate the temperature of the battery cells, while others can meet the cooling requirements of the liquid-cooled PCS system. Therefore, the liquid-cooled PCS system can be installed inside the box 100, meeting the AC / DC requirements of the energy storage container.

[0069] refer to Figure 4 After installing fan 320 on the top of housing 100, the spacious top space allows for a larger fan 320 to be installed. Compared to smaller fans 320 in the prior art, the larger fan 320 rotates at a lower speed while maintaining the same temperature regulation capability of the heat pump system, thus reducing noise during operation. Since energy storage containers require ambient noise testing, installing fan 320 on the top can reduce ambient noise around housing 100. Testing has shown that ambient noise levels around existing energy storage containers are 80dB, while the energy storage container provided by the present embodiment is within 75dB.

[0070] In addition, since the fan 320 is placed on top, there will be no hot air circulation when multiple energy storage containers are arranged side by side, so the energy storage containers can be placed more compactly in the station, which can reduce the floor space occupied by the energy storage containers.

[0071] Discharging hot air through the top of the fan can prevent heat from accumulating in the station and forming a heat island effect. The heat pump fan discharges the hot air, which has a higher heat dissipation efficiency than some existing energy storage containers that have exhaust vents on the top to discharge the hot air through the natural upward floating of the hot air.

[0072] Example 2

[0073] Figure 5 This is a schematic diagram of the energy storage container structure provided in the embodiment of the present application. Figure 2 ,like Figure 5 As shown, the air inlet of the heat pump system is arranged at the top of the box body 100, and the air inlet baffle 30 is arranged at the air inlet.

[0074] By locating both the air inlet and fan 320 at the top of the housing 100, it is possible to ensure that when multiple energy storage containers are arranged side by side, the hot air exhausted by the fan 320 will not be sucked into other energy storage containers. Furthermore, compared to designs where the air inlet is located on the side of the housing 100, the top-mounted air inlet can further conserve the area of ​​the side of the housing 100. Furthermore, since air does not enter the sides of the housing 100, the energy storage containers can be arranged more densely within the station. Furthermore, the air inlet baffle 30 can prevent debris from entering the heat pump system and damaging it.

[0075] Example 3

[0076] Figure 6 This is a schematic diagram of the energy storage container structure provided in the embodiment of the present application. Figure 3 ,like Figure 6 As shown, a partition beam 500 is provided within the top space. The heat exchange assembly 300 is mounted above the partition beam 500 and connected to the housing 100. The partition beam 500 can be a beam frame structure composed of multiple connected beams, or a plate-shaped support member. The partition beam 500 can be arranged along the length of the housing 100 or along the transverse direction of the housing 100. The heat exchange assembly 300 can be secured to the partition beam 500 via a mounting bracket 510.

[0077] In this embodiment, a fire protection system 600 may be provided and installed below the partition beam 500. The fire protection system 600 is primarily used to monitor the battery compartment 200 below for fire and to extinguish any fire in the battery compartment 200. The fire protection system 600 may include sprinklers, various sensors such as smoke sensors, fire protection gas pipes and lines, and the like.

[0078] Figure 7This is a schematic diagram of the energy storage container structure provided in the embodiment of the present application. Figure 4 ,like Figure 7 As shown, the partition beam 500 includes a first beam frame 520 and a second beam frame 530. The first beam frame 520 and the second beam frame 530 are both connected to the box body 100, and the first beam frame 520 is located above the second beam frame 530. The first beam frame 520 and the second beam frame 530 can be formed by connecting multiple beam bodies, or the first beam frame 520 and the second beam frame 530 can be an integrated plate-shaped support member, with the higher portion on one side of the plate-shaped support member serving as the first beam frame 520 and the lower portion on the other side serving as the second beam frame 530.

[0079] The heat exchange assembly 300 is installed above the second beam 530 , and the fire protection system 600 is installed below the first beam 520 .

[0080] Since the heat exchange assembly 300 is large in size and the fire protection system 600 also has many components, by designing the partition beam 500 into a "Z" shape with the first beam frame 520 high and the second beam frame 530 low, the limited top space can be fully utilized, and the partition beam 500 can provide a stable installation support for the fire protection system 600 and the heat exchange assembly 300.

[0081] Example 4

[0082] Figure 8 Schematic diagram of the energy storage container structure provided in the embodiment of this application Figure 5 The partition beam 500 further includes a main beam 50 , which is arranged along the length of the box body 100 , and both ends of the main beam 50 are connected to the box body 100 , a first beam frame 520 and a second beam frame 530 are connected to the main beam 50 , respectively, and the first beam frame 520 is higher than the second beam frame 530 .

[0083] The top plate of the box body 100 is connected below the first beam 520 . The nozzles, various sensors, fire-fighting gas pipelines and lines of the fire-fighting system 600 are installed below the top plate of the box body 100 . The heat exchange assembly 300 is installed above the second beam 530 .

[0084] In this embodiment, the main beam 50 is a square tube, and the first beam frame 520 and the second beam frame 530 can be made of square tube processed beams spliced ​​and welded. In this embodiment, the main beam 50 and the spliced ​​and welded first beam frame 520 and second beam frame 530 can improve the structural strength of the partition beam 500.

[0085] In a possible embodiment of the present application, an energy storage container system is further provided, comprising a plurality of the above-mentioned energy storage containers, wherein the plurality of the above-mentioned energy storage containers are arranged side by side.
