Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to an energy storage container. Background Art

[0002] Energy storage containers need to arrange energy storage batteries, battery racks, refrigeration units, electrical systems and other equipment within the limited space of the container. Existing energy storage containers usually have the refrigeration unit and the electrical system installed in the container, and the refrigeration unit and the electrical system are located at the same end of the container. This layout makes the space occupied by the refrigeration unit in the container limited, and when installing the refrigeration unit, it is necessary to avoid the installation space for the electrical system, which greatly restricts the installation of the refrigeration unit.

[0003] When the energy stored in the energy storage battery increases and the charge and discharge rate of the energy storage battery increases, the heat generated by the energy storage battery will increase accordingly. At this time, the cooling power of the refrigeration unit needs to be increased to meet the gradually increasing cooling demand of the energy storage battery. The increase in the cooling power of the refrigeration unit requires the expansion of the installation area of ​​the refrigeration unit to accommodate higher-power compressors, water pumps, condensers and other components. However, the existing container layout method cannot meet the demand for expanding the installation volume of the refrigeration unit, and thus cannot meet the increased cooling demand of the energy storage battery. If the refrigeration unit is to be installed on the outside of the container, the container and the refrigeration unit need to be transported separately during transportation. After being transported to the installation site, the refrigeration unit needs to be assembled and injected on-site at the installation site, which increases the difficulty and cost of on-site installation.

[0004] Therefore, it is urgent to propose an energy storage container to solve the above technical problems. Utility Model Content

The refrigeration unit is arranged in the refrigeration compartment, the electrical system is arranged in the electrical compartment, and the battery system is arranged in the battery compartment.

[0008] Optionally, the box body further includes an air inlet and an air outlet, and the air inlet and the air outlet are connected to the refrigeration chamber.

[0009] Optionally, the air inlet and the air outlet are both opened on the side wall in the width direction of the box body.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0029] This embodiment provides an energy storage container, the refrigeration unit of which is more flexible to install and can meet the higher cooling demand of the battery system.

[0030] Specifically, Figure 1 and Figure 2 As shown, the energy storage container includes a box body 100, a refrigeration unit 200, an electrical system and a battery system 300. Figure 1 The interior space of the box 100 includes a refrigeration compartment 110, a battery compartment 130, and an electrical compartment 120, respectively. The refrigeration compartment 110 and the electrical compartment 120 are located at both ends of the length direction of the box 100, and the width direction of the box 100 ( Figure 1 In the y direction), the size of the refrigeration compartment 110 is equal to the size of the box body 100, that is, the refrigeration compartment 110 covers the entire width of the box body 100, the refrigeration unit 200 is arranged in the refrigeration compartment 110, the electrical system is arranged in the electrical compartment 120, and the battery system 300 is arranged in the battery compartment 130.

[0031] Based on the above design, the energy storage container arranges the refrigeration compartment 110 and the electrical compartment 120 at the two ends of the box body 100 along the length direction of the box body 100, respectively, arranges the refrigeration unit 200 in the refrigeration compartment 110, and arranges the electrical system in the electrical compartment 120. When installing the refrigeration unit 200 in the refrigeration compartment 110, there is no need to consider the problem of avoiding the electrical system, which makes the installation of the refrigeration unit 200 more flexible.

[0032] On the other hand, the refrigeration chamber 110 fills the internal space of the box body 100 in the width direction of the box body 100, expanding the volume of the refrigeration chamber 110 as much as possible, providing sufficient installation space for the refrigeration unit 200 arranged in the refrigeration chamber 110, and then a refrigeration unit 200 with a larger volume and a larger cooling capacity can be installed in the refrigeration chamber 110 to meet the higher cooling demand of the battery system 300.

[0033] On the other hand, compared with the form of an external refrigeration unit 200, the energy storage container provided in this embodiment can install the refrigeration unit 200 inside the box body 100, and can transport the box body 100, the refrigeration unit 200, the electrical system and the battery system 300 as a whole. After being transported to the installation site, there is no need to assemble and inject liquid on site for the refrigeration unit 200, which greatly simplifies the on-site installation process and reduces the installation cost and difficulty.

[0034] Optionally, the refrigeration unit 200 is a liquid cooling unit, that is, the refrigerant at the evaporator end exchanges heat with the cooling liquid, and then the cooling liquid is used to absorb the heat of the battery system 300. Further, the refrigeration unit 200 in this embodiment is an air-cooled liquid cooling unit, that is, the refrigerant at the condenser end exchanges heat with the air. The air-cooled liquid cooling unit used in this embodiment is a common refrigeration unit 200 in the art, such as Figure 3 As shown, the refrigeration unit 200 includes a compressor 210, a plate heat exchanger 220, and a water pump 230, etc., and its specific working principle is not repeated here.

[0035] Alternatively, if Figure 1 As shown, the box body 100 further includes an air inlet 140 and an air outlet 150 , and the air inlet 140 and the air outlet 150 are connected to the refrigeration chamber 110 , so as to achieve the effect of cooling and ventilating the refrigeration unit 200 in the refrigeration chamber 110 .

[0036] In the prior art, usually only the air outlet is opened on the side wall in the width direction of the box body, and the air inlet is opened on the side wall in the length direction of the box body. Since the air inlet needs to correspond to the position of the refrigeration chamber, and other structures need to be set on the side wall in the length direction of the box body, the structure of setting the air inlet on the side wall in the length direction of the box body limits the size of the air inlet, and thus cannot increase the air intake volume of the refrigeration chamber. In order to solve this technical problem, Figure 1 As shown, in this embodiment, the air inlet 140 and the air outlet 150 are both opened on the side wall of the box body 100 in the width direction. The size design of the air inlet 140 does not need to consider other structures on the side wall of the box body 100 in the length direction. Therefore, the area of ​​the air inlet 140 can be expanded, thereby increasing the air intake volume of the refrigeration chamber 110.

[0037] Furthermore, if Figure 1 As shown, the air inlet 140 and the air outlet 150 are distributed along the height direction of the box body 100, further expanding the area of ​​the air inlet 140 and the air outlet 150.

[0038] Preferably, if Figure 1As shown, the air inlet 140 is located below the air outlet 150. Since the density of cold air is greater than that of hot air, the air inlet 140 is opened below the air outlet 150, which is beneficial for the air with lower temperature outside the box 100 to enter the refrigeration chamber 110 through the air inlet 140 to exchange heat with the refrigeration unit 200.

[0039] Alternatively, if Figure 1 As shown, the electrical compartment 120 fills the internal space of the box body 100 in the width direction of the box body 100, that is, in the width direction of the box body 100, the size of the electrical compartment 120 is equal to the size of the box body 100, and the volume of the electrical compartment 120 is expanded as much as possible to provide sufficient installation space for the electrical system arranged in the electrical compartment 120.

[0040] Alternatively, if Figure 2 and Figure 4 As shown, the energy storage container also includes a fire protection system, which includes a fire protection host 520, a fire protection gas cylinder 510 and a fire protection pipeline. One end of the fire protection pipeline is connected to the fire protection gas cylinder 510, and the other end is connected to the battery compartment 130. When a fire occurs in the battery system 300, under the control of the fire protection host 520, the fire extinguishing medium in the fire protection gas cylinder 510 is sprayed into the battery compartment 130 through the fire protection pipeline to control the fire. It should be pointed out that the specific materials of the above-mentioned fire extinguishing medium and the control method of the fire protection host 520 are both existing technologies in the field and will not be repeated here.

[0041] Furthermore, the electrical compartment 120 includes an electrical area and a fire protection area. The electrical system is arranged in the electrical area. The fire protection host 520 and the fire protection gas cylinder 510 are both arranged in the fire protection area to improve the internal space utilization of the electrical compartment 120.

[0042] Alternatively, if Figure 4 As shown, the fire protection area and the electrical area are arranged along the height direction of the box body 100 ( Figure 1 The electrical compartment 120 is distributed in the z direction to fully utilize the height space of the electrical compartment 120 and further improve the space utilization of the cabinet 100.

[0043] Furthermore, if Figure 4 As shown, the fire protection area is located above the electrical area. In actual applications, the electrical system is usually regularly inspected and maintained. Setting the electrical area below the fire protection area is beneficial to reducing the difficulty of electrical system inspection and maintenance and improving inspection and maintenance efficiency.

[0044] Specifically, Figure 4As shown, the electrical system includes a junction box 410, a power distribution box 420, a high-voltage box, and a power conversion system (PCS) (the high-voltage box and the PCS are not shown in the figure), etc. The junction box 410 and the power distribution box 420 are arranged at intervals along the width direction of the box body 100. A gas cylinder bracket 530 and a host bracket (not shown in the figure) are installed in the electrical compartment 120. The gas cylinder bracket 530 is located above the junction box 410, the fire gas cylinder 510 is arranged on the gas cylinder bracket 530, the host bracket is located above the power distribution box 420, and the fire host 520 is arranged on the host bracket. Of course, in other implementation schemes, the fire host 520 can also be arranged on the power distribution box 420, depending on the actual application requirements.

[0045] The energy storage container provided in this embodiment takes a twenty-foot high standard size container body 100 and a six-group battery system 300 as an example, and arranges the refrigeration compartment 110 and the electrical compartment 120 at the two ends of the body 100 along the length direction of the body 100, respectively, so as to avoid the problem that the refrigeration unit 200 needs to avoid the electrical system when the refrigeration compartment 110 and the electrical compartment 120 are arranged on the same side of the body 100, and the refrigeration compartment 110 covers the internal space of the body 100 in the width direction of the body 100, making full use of the length space and width space of the body 100, expanding the volume of the refrigeration compartment 110 as much as possible, and providing sufficient installation space for the refrigeration unit 200 arranged in the refrigeration compartment 110, so that a refrigeration unit 200 with a larger volume and a larger cooling capacity can be installed in the refrigeration compartment 110 to meet the higher cooling demand of the battery system 300, and the design layout of the refrigeration unit 200 does not need to be too compact, so that more ventilation ducts can be reserved for the refrigeration unit 200 to dissipate heat, which is conducive to improving the refrigeration efficiency of the refrigeration unit 200.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
