Description

Technical Field

[0001] This invention relates to an integrated photovoltaic, energy storage, and charging container. Background Technology

[0002] With the rapid development of the new energy industry, energy storage technology, as a key support for energy transformation, has become a research hotspot in the global energy field. Energy storage containers, as an integrated and modular energy storage solution, are widely used in grid peak shaving, renewable energy grid integration, and distributed energy systems due to their advantages in ease of transportation, installation, and maintenance.

[0003] However, existing energy storage containers still have the following problems: The photovoltaic panels of existing energy storage containers are automatically deployed by a flip-type mechanism, but this method is not conducive to maintenance. Maintenance can only be carried out after the solar panels are fully deployed. Secondly, this flip-type mechanism requires a large amount of upper space, making it difficult to deploy when the device is placed in a narrow space. It is also not conducive to the maintenance of the deployment mechanism. At the same time, the existing cooling system has a complex structure, high maintenance costs, and uneven cooling effect, making it difficult to ensure that the battery modules work within the optimal temperature range.

[0004] Therefore, there is an urgent need for an integrated energy storage container with a structure that is easy to maintain and has good heat dissipation to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated photovoltaic, energy storage, and charging container. Through a telescopic structure, the structure is simpler and the space utilization rate is higher. Furthermore, it employs multiple cooling components, each capable of independently cooling the battery pack, achieving a more uniform cooling effect. These objectives of this invention are achieved as follows:

[0006] This invention proposes an integrated photovoltaic-storage-charging energy storage container, comprising a container assembly, battery components, and cooling components. The container assembly has a rectangular frame structure. Several battery components are installed inside the container assembly, and several cooling components are distributed correspondingly below the battery components, symmetrically distributed on both sides of the container assembly. Each cooling component forms a cooling chamber. The side surface of each cooling component has an air inlet and an air outlet extending horizontally into the cooling chamber. The air outlet is located above the air inlet. Airflow passes through the air inlet and the cooling chamber and exits through the air outlet. A first air inlet control component is located on one side of the air inlet to control the air intake, and a second air inlet control component is located on one side of the air outlet to control the air exhaust. The container also includes a support plate installed on the upper part of the container assembly for mounting a first solar panel. A telescopic assembly is installed between the support plate and the container assembly for extending or retracting relative to both sides of the container assembly. A telescopic plate is installed on each side of the telescopic assembly, and a second solar panel is mounted on the telescopic plate.

[0007] Furthermore, a partition is installed in the center of the cooling chamber to separate the corresponding cooling components on the left and right sides. The cooling components are fixed to the inside of the housing assembly by bolts, and the battery assembly is fixed to the inside of the housing assembly by bolts. A heat-conducting plate is distributed between the battery assembly and the cooling components, and the two sides of the heat-conducting plate are respectively connected to the battery assembly and the cooling components by bolts.

[0008] Furthermore, the first air intake control component includes a preset fan for supplying air into the cooling chamber, the preset fan being bolted inside the air inlet; the second air intake control component includes a preset fan assembly for exhausting air into the cooling chamber, the preset fan assembly being bolted inside the air outlet.

[0009] Furthermore, the air outlet has a rectangular cross-section, the air inlet has a rectangular cross-section, and the cross-section of the air outlet is smaller than that of the air inlet.

[0010] Furthermore, a filter plate is bolted to the air inlet and a filter plate is bolted to the air outlet.

[0011] Furthermore, the telescopic assembly is installed on the upper part of the battery assembly and is electrically connected to the battery assembly. The telescopic assembly includes a preset motor and a preset telescopic rod. The preset motor is used to provide power to the preset telescopic rod to realize the left and right telescopic movement of the telescopic rod. A telescopic plate is installed on the telescopic rod by bolts.

[0012] Furthermore, the frame columns are installed together by connectors and fixed by bolts, and the support plate is connected to the frame columns by bolts.

[0013] Furthermore, the first solar panel has eight sections, and each of the telescopic panels has four second solar panels installed on it. The first solar panels are bolted to the upper part of the support plate, and the second solar panels are bolted to the upper part of the telescopic panel.

[0014] Furthermore, it also includes a liquid chiller and a fire cabinet. The liquid chiller is connected to the battery pack via a pre-set pipe, and the fire cabinet is also connected to the battery pack via a pre-set pipe. A charging pile is also installed on one side of the enclosure assembly. The charging pile is electrically connected to the battery pack for charging the battery pack. A cable winch is installed on the upper part of the enclosure assembly for connecting with a mobile winch arranged on one side of the enclosure assembly to realize the movement of the enclosure assembly.

[0015] Compared with the prior art, the beneficial effects of the present invention are: through the design of the telescopic component, the second solar panel is installed at the lower part of the first solar panel, and the staff can stand directly on the upper part of the first solar panel and then extend the second solar panel. The telescopic component can be maintained at the same time as the second solar panel, which reduces the labor force during maintenance. The structure is simple, the space utilization rate is high, and it is easy to maintain.

[0016] By symmetrically distributing the cooling components on both sides of the housing assembly, and setting air inlets and outlets on the side surfaces of the cooling components, airflow can pass through the air inlets and cooling chamber and be discharged from the outlets. At the same time, the airflow is controlled by the first air inlet control component and the second air inlet control component, respectively, to increase the heat dissipation efficiency. Each air inlet control component can be controlled independently to improve heat dissipation efficiency and uniformity. Attached Figure Description

Detailed Implementation

[0026] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0027] Example 1:

[0028] Please refer to Figure 1-8 This invention provides an integrated photovoltaic-storage-charging energy storage container, comprising a container assembly 100, battery modules 600, and cooling modules 700. The container assembly 100 has a rectangular frame structure. Several battery modules 600 are installed inside the container assembly 100. Several cooling modules 700 are correspondingly distributed below the battery modules 600, and the cooling modules 700 are symmetrically distributed on both sides of the container assembly 100. Each cooling module 700 forms a cooling chamber. The side surface of each cooling module 700 has an air inlet 740 and an air outlet 730 extending horizontally into the cooling chamber. The air outlet 730 is located above the air inlet 740. Force is discharged from air outlet 730 through air inlet 740 and cooling chamber. A first air inlet control component 710 is provided on one side of air inlet 740 to control the air intake volume. A second air inlet control component 720 is provided on one side of air outlet 730 to control the air outlet volume. It also includes a support plate 140, which is installed on the upper part of the housing assembly 100 and is used to install the first solar panel 200. A telescopic component 120 is installed between the support plate 140 and the housing assembly 100 for extending or retracting relative to both sides of the housing assembly 100. A telescopic plate 130 is installed on each side of the telescopic component 120, and a second solar panel 500 is installed on the telescopic plate 130.

[0029] A partition 750 is installed at the center of the cooling chamber to separate the corresponding cooling components 700 on the left and right sides. The cooling components 700 are fixed to the inside of the housing assembly 100 by bolts. The battery assembly 600 is fixed to the inside of the housing assembly 100 by bolts. A heat-conducting plate 400 is distributed between the battery assembly 600 and the cooling components 700. The two sides of the heat-conducting plate 400 are respectively connected to the battery assembly 600 and the cooling component 700 by bolts. The first air inlet control assembly 710 includes a preset fan for directing airflow to the cooling components. Air is supplied to the cooling chamber. The preset fan is bolted to the air inlet 740. The second air intake control component 720 includes a preset fan group for drawing air into the cooling chamber. The preset fan group is bolted to the air outlet 730. The air outlet 730 has a rectangular cross-section, and the air inlet 740 has a rectangular cross-section. The cross-section of the air outlet 730 is smaller than that of the air inlet 740. A filter plate 760 is bolted to the air inlet 740 and the air outlet 730 is bolted to the air outlet 730. The working principle is as follows: When it is necessary to increase power generation, the control system starts the preset motor, which drives the telescopic rod to extend to both sides, causing the telescopic plate 130 and the second solar panel 500 installed on it to extend to both sides of the box, increasing the photovoltaic receiving area; when it is necessary to move the device or encounters bad weather, the control system causes the preset motor to run in reverse, retracting the telescopic rod, so that the telescopic plate 130 and the second solar panel 500 return to the inside of the box, protecting the equipment and reducing the space occupied. During maintenance, the first solar panel 200 is maintained first, and the second solar panel 500 can be opened at any time. While maintaining the second solar panel 500, the telescopic component 120 can also be maintained.

[0030] The telescopic assembly 120 is installed on the upper part of the battery assembly 600 and is electrically connected to the battery assembly 600. The telescopic assembly 120 includes a preset motor and a preset telescopic rod. The preset motor provides power to the preset telescopic rod to realize the left and right telescopic movement of the telescopic rod. A telescopic plate 130 is installed on the telescopic rod by bolts. The frame columns 110 are installed together by connectors 150 and fixed by bolts. The support plate 140 is connected to the frame columns 110 by bolts. There are eight first solar panels 200. Four second solar panels 500 are installed on each telescopic plate 130. The first solar panels 200 are installed on the upper part of the support plate 140 by bolts, and the second solar panels 500 are installed on the upper part of the telescopic plate 130 by bolts. In one application scenario, when the battery assembly 600 generates heat during operation, the heat is first transferred to the heat conduction plate 400, and then transferred by the heat conduction plate 400 to the cooling assembly 700. The preset fan of the first air intake control assembly 710 sends external cold air into the cooling chamber, while the preset fan group of the second air intake control assembly 720 draws hot air out from the air outlet 730, forming forced convection and accelerating heat dissipation. Since the cross-section of the air outlet 730 is smaller than that of the air inlet 740, the air speed increases when flowing through the cooling chamber, further enhancing the heat dissipation effect. Throughout the heat dissipation process, the partition 750 divides the cooling chamber into two independent spaces, so that the heat dissipation of the battery assemblies 600 on both sides does not interfere with each other, thus improving the heat dissipation efficiency. It also includes a liquid chiller 1 and a fire cabinet 2. The liquid chiller 1 is connected to the battery pack 600 through a pre-set pipe, and the fire cabinet 2 is connected to the battery pack 600 through a pre-set pipe. A charging pile 3 is also installed on one side of the enclosure assembly 100. The charging pile 3 is electrically connected to the battery pack 600 for charging the battery pack 600. A cable winch 900 is installed on the upper part of the enclosure assembly 100 for connecting with a mobile winch 800 arranged on one side of the enclosure assembly 100 to realize the movement of the enclosure assembly 100.

[0031] Example 2:

[0032] The internal structure of the cooling assembly 700 of the present invention is as follows:

[0033] As a preferred cooling method, the cooling assembly 700 includes a cooling chamber, a cooling cart, refrigerant piping, and a control system. The cooling chamber has a rectangular structure with an internal space of 12 meters × 2 meters × 2 meters. The cooling cart has a cuboid structure with dimensions of 1 meter × 1 meter × 0.5 meters, and is equipped with casters at the bottom for easy movement. The refrigerant piping is located inside the outer wall of the cooling chamber, with a length of 8 meters and an inner diameter of 10 millimeters. The control system includes temperature sensors, controllers, and solenoid valves, used to automatically adjust the refrigerant flow rate based on temperature data fed back from the temperature sensors. A partition 750 divides the cooling chamber into two halves, with a cooling cart installed in each half. The two half-chambers are connected to the refrigerant piping through through holes in the partition 750. The bottom of the cooling cart has a refrigerant outlet and inlet, connected to the refrigerant piping via solenoid valves. The outer shell of the cooling cart is made of copper, and the inner liner is made of stainless steel for heat conduction. Several temperature sensors are also installed inside the cooling chamber to detect the temperature in different areas. The temperature sensors are model PT100 with an accuracy of ±0.1℃. The controller uses a PLC controller, model S7-300, which features digitalization and intelligence. Based on temperature data from temperature sensors, it automatically adjusts the refrigerant flow to achieve precise cooling control. Specifically, when the temperature of a certain cooling half-chamber exceeds the set value, the control system automatically closes the solenoid valve of that half-chamber and starts the refrigerant flow to the opposite half-chamber, achieving rapid switching of cooling effect. Through continuous monitoring by temperature sensors and automatic adjustment by the control system, the temperature inside the cooling chamber is kept within the set range, achieving uniform and stable cooling.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
