Description

Technical Field

[0001] This utility model belongs to the field of energy storage cabinet technology, specifically relating to an integrated energy storage cabinet that combines source, grid, load and storage. Background Technology

[0002] The source-grid-load-storage (PGS) system is an operational model that integrates a comprehensive solution encompassing power supply, grid, load, and energy storage. The principle of a PGS system is to store excess energy in energy storage devices when energy supply is sufficient, for unforeseen circumstances. When energy supply is insufficient, the storage devices release the stored energy to meet user needs. PGS systems enable efficient energy utilization and flexible dispatching, improve grid reliability and stability, and can be used in industrial parks, data centers, agricultural parks, charging stations, and other similar locations.

[0003] The core equipment of the energy storage system (energy source, grid, load, and energy storage) is the energy storage cabinet. Inside the cabinet are battery boxes, along with associated electrical modules such as inverters and temperature control units. Multiple battery boxes are installed, each containing multiple battery cells. The bottom of each battery box has cooling water channels connected to the temperature control unit, which circulate cooling water to cool the battery cells. The battery boxes are relatively heavy, requiring them to be hoisted to a suitable height before being pushed into the cabinet's storage space, and finally secured with fasteners. This installation method easily scratches the bottom of the battery boxes and is quite laborious. Utility Model Content

[0004] This utility model provides an integrated energy storage cabinet that combines power generation, grid, load and storage, aiming to solve the problems of laborious battery box installation and easy slippage and wear at the bottom of the battery box in the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide an integrated energy storage cabinet comprising:

[0006] The cabinet has a battery compartment and an electrical compartment, with an opening formed on one side of each compartment.

[0008] A battery bracket is disposed within the battery cavity. The battery bracket has multiple support units spaced apart from top to bottom. The support units are horizontally arranged. Each support unit has a receiving groove on its upper surface. Multiple sets of receiving grooves are spaced apart in the width direction of the support unit. Each set of receiving grooves has two receiving grooves in the length direction of the support unit. The length direction of the support unit is parallel to the opening direction of the battery cavity, and the width direction of the support unit is perpendicular to the opening direction of the battery cavity.

[0009] Multiple battery boxes are correspondingly mounted on the supporting unit. The bottom of each battery box has multiple sets of rolling elements along the width direction of the supporting unit. Each set of rolling elements has two rolling elements along the length direction of the supporting unit. The rolling elements are correspondingly housed within the receiving groove, and the height of each rolling element protruding from the bottom surface of the battery box is less than the depth of the receiving groove.

[0010] An electrical component is located within the electrical cavity and is electrically connected to the battery box.

[0011] In one possible implementation, the battery cavity is located above the electrical cavity, and a partition is provided between the battery cavity and the electrical cavity. The partition has a through hole that connects the battery cavity and the electrical cavity.

[0012] In one possible implementation, the support unit includes two support plates, which are disposed opposite to each other on the two side walls of the battery cavity, and each support plate has two receiving grooves formed in the length direction of the support unit.

[0013] In one possible implementation, guide strips are provided on opposite sides of the two support plates, and a guide slope is formed on the side of the guide strip adjacent to the opening of the battery cavity. A guide channel is formed between the guide slopes of the two guide strips, and the guide channel tends to expand outward in the opening direction of the battery cavity.

[0014] In one possible implementation, the side of the receiving groove adjacent to the opening of the battery cavity is a buffer slope. When the rolling element moves above the buffer slope, the rolling element rolls in cooperation with the buffer slope. The rolling element is a cylindrical roller or a ball.

[0015] In one possible implementation, the battery box includes:

[0016] The housing has a cavity for accommodating the battery;

[0017] Multiple battery cells are respectively disposed within the receiving cavity, and the battery cells are electrically connected to the electrical components; and

[0018] A bottom shell is located at the bottom of the housing. A flow channel groove is formed on one side of the bottom shell that is in contact with the housing. The flow channel groove and the bottom surface of the housing form a liquid cooling flow channel. The rolling element is located on the bottom shell.

[0019] In one possible implementation, the bottom of the cabinet is provided with a bracket, the bracket has a through transfer groove in the horizontal direction, at least two of the transfer grooves are provided on the side of the bracket, and multiple transfer grooves are arranged in parallel. The side of the bracket is provided with a sealing plate, the sealing plate is placed over the opening of the transfer groove and is detachably connected to the bracket.

[0020] In one possible implementation, the top of the cabinet is provided with a hanging ring.

[0021] In one possible implementation, the battery box has a first mounting hole, and the support unit has a second mounting hole corresponding to the first mounting hole.

[0023] Compared with existing technologies, the beneficial effects of the integrated energy storage cabinet for source, grid, load and storage provided by this utility model are:

[0024] This utility model provides an integrated energy storage cabinet comprising a cabinet body, a cabinet door, a battery bracket, a battery box, and electrical components. The cabinet body forms a battery cavity and an electrical cavity, with the electrical components housed within the electrical cavity. The battery bracket and battery box are housed within the battery cavity, and the cabinet door is used to close the battery cavity and electrical cavity. The battery bracket has multiple support units from top to bottom, each with a receiving groove. The battery box has rolling elements at its bottom, protruding from the bottom surface of the battery box. During battery box installation, the battery box is hoisted to the installation height and then pushed onto the battery bracket. The rolling elements contact the upper surface of the battery bracket, reducing the pushing resistance and allowing the battery box to be pushed into the battery cavity more easily. Once the battery box is in place, the rolling elements are positioned within the receiving groove. Because the depth of the receiving groove is greater than the protrusion height of the rolling elements, the bottom surface of the battery box contacts the support unit, providing support. The rolling elements are suspended within the receiving groove, thus avoiding stress and preventing damage from long-term support of the battery box.

[0025] This invention features a receiving groove on the battery holder and a rolling element at the bottom of the battery box, with the height of the rolling element protruding from the bottom of the battery box less than the depth of the receiving groove. This reduces the contact area between the rolling element and the supporting unit during battery box installation, thereby reducing pushing resistance and making the battery box easier to install. It also prevents scratches on the bottom of the battery box. Once the battery box is installed, the rolling element is suspended within the receiving groove and will not be damaged even after long-term use. Attached Figure Description

[0042] Please refer to the following: Figures 1 to 8 The following describes an integrated energy storage cabinet for source, grid, load and storage provided in an embodiment of this application.

[0043] Please see Figures 1 to 6 This application provides an integrated energy storage cabinet comprising a cabinet body 10, a cabinet door 20, a battery bracket 30, a battery box 40, and electrical components. The cabinet body 10 has a battery cavity 11 and an electrical cavity 12, each with an opening on one side. The cabinet door 20 is located at the openings of the battery cavity 11 and the electrical cavity 12 and is movably connected to the cabinet body 10. The battery bracket 30 is located within the battery cavity 11 and has multiple support units spaced apart from top to bottom. The support units are horizontally arranged, and each support unit has a receiving groove 311 on its upper surface. Multiple sets of receiving grooves 311 are spaced apart along the width direction of the support unit, and each set of receiving grooves 311 has two receiving grooves 311 along the length direction of the support unit. The length direction of the unit is parallel to the opening direction of the battery cavity 11, and the width direction of the supporting unit is perpendicular to the opening direction of the battery cavity 11. Multiple battery boxes 40 are correspondingly arranged on the supporting units. Multiple sets of rolling elements 44 are provided at the bottom of the battery box 40 along the width direction of the supporting unit. Each set of rolling elements 44 has two rolling elements 44 along the length direction of the supporting unit. The rolling elements 44 are correspondingly housed in the receiving groove 311, and the height of the rolling elements 44 protruding from the bottom surface of the battery box 40 is less than the depth of the receiving groove 311. Electrical components are located in the electrical cavity 12 and are electrically connected to the battery box 40. Battery components, such as inverters, power modules, wireless modules, and cooling units, are existing electrical components of the energy storage cabinet, and their specific structures and working principles will not be described in detail.

[0044] Compared with the prior art, the beneficial effects of the integrated energy storage cabinet for source, grid, load and storage provided in this embodiment of the present invention are:

[0045] The integrated energy storage cabinet provided in this embodiment includes a cabinet body 10, a cabinet door 20, a battery bracket 30, a battery box 40, and electrical components. The cabinet body 10 forms a battery cavity 11 and an electrical cavity 12. The electrical components are disposed in the electrical cavity 12, and the battery bracket 30 and battery box 40 are disposed in the battery cavity 11. The cabinet door 20 is used to close the battery cavity 11 and the electrical cavity 12. The battery bracket 30 has multiple supporting units from top to bottom, and the supporting units have receiving grooves 311. The bottom of the battery box 40 is provided with a rolling element 44, which protrudes from the bottom surface of the battery box 40. When installing the battery box 40, the battery box 40 is hoisted to the installation height, and then the battery box 40 is pushed onto the battery bracket 30. The rolling element 44 contacts the upper surface of the battery bracket 30, which can reduce the pushing resistance of the battery box 40, making it easier to push the battery box 40 into the battery cavity 11. Once the battery box 40 is in place, the rolling element 44 is positioned within the receiving groove 311. Since the depth of the receiving groove 311 is greater than the protrusion height of the rolling element 44, the bottom surface of the battery box 40 contacts the supporting unit, providing support. The rolling element 44 is suspended within the receiving groove 311, thus avoiding stress on it and preventing damage from prolonged support of the battery box 40.

[0046] This embodiment of the invention provides a receiving groove 311 on the battery bracket 30 and a rolling element 44 at the bottom of the battery box 40. The rolling element 44 protrudes from the bottom surface of the battery box 40 at a height less than the depth of the receiving groove 311. This reduces the contact area between the battery box 40 and the supporting unit during installation, thereby reducing pushing resistance and making it easier to install the battery box 40. It also prevents scratches on the bottom of the battery box 40. After the battery box 40 is installed, the rolling element 44 is suspended within the receiving groove 311 and will not be damaged even after long-term use.

[0047] The cabinet body 10 and cabinet door 20 can be made of stainless steel or other metal materials. The cabinet body 10 is a frame formed by welding steel profiles. The frame structure has high strength and is not easily deformed or damaged. The outside of the frame is covered with stamped steel plates, which serve both aesthetic and protective purposes. The cabinet body 10 contains a battery cavity 11 and an electrical cavity 12. The battery cavity 11 is used to house the battery bracket 30 and battery box 40, while the electrical cavity 12 is used to house electrical equipment such as inverters, controllers, transformers, and cooling units.

[0048] The cabinet door 20 is movably connected to the cabinet body 10. The cabinet door 20 can be connected to the cabinet body 10 by hinges or by a latch.

[0049] Battery bracket 30 is used to support battery box 40. Battery bracket 30 includes multiple support units, which can be arranged as follows: Figure 2 As shown, it is directly installed onto the frame of the cabinet 10, specifically by bolts or welding. The battery bracket 30 has receiving slots 311, with multiple sets of slots 311 in the width direction, specifically two sets. There are also two receiving slots 311 in the length direction.

[0050] There are no restrictions on the depth of the receiving groove 311 and the protrusion height of the rolling element 44. For example, the protrusion height of the rolling element 44 can be 3mm and the depth of the receiving groove 311 can be 5mm.

[0051] The battery box 40 is typically a square, enclosed shell. Inside the battery box 40 are battery cells, which can be existing energy storage batteries such as lithium batteries or lead-acid batteries. The number and position of the rolling elements 44 at the bottom of the battery box 40 correspond to the receiving grooves 311. During the pushing process of the battery box 40, the rolling elements 44 contact the supporting surface of the supporting unit, providing support. When the battery box 40 is installed in place, the rolling elements 44 are precisely accommodated within the receiving grooves 311. Figure 6 As shown, the rolling element 44 is a cylindrical roller, but it can also be other shapes, such as spherical balls. The rolling element 44 is embedded in or mounted in the groove via a shaft, and will not fall out during use. The rolling element 44 can be made of steel, which is strong and not easily damaged.

[0052] Please see Figure 1 In some possible embodiments, the battery cavity 11 is located above the electrical cavity 12, and a partition 13 is provided between the battery cavity 11 and the electrical cavity 12. A wire hole is provided on the partition 13, which connects the battery cavity 11 and the electrical cavity 12. The wire hole is used for wiring and cooling pipes to pass through.

[0053] Please see Figure 2 and Figure 3 In some possible embodiments, the support unit includes two support plates 31, which are disposed opposite to each other on the two side walls of the battery cavity 11. Each support plate 31 has two receiving slots 311 in the length direction of the support unit, and the two sides of the battery box 40 are supported on the two side support plates 31.

[0054] Please see Figure 3In some possible embodiments, guide strips 312 are provided on opposite sides of the two support plates 31. A guide slope 313 is formed on the side of the guide strip 312 adjacent to the opening of the battery cavity 11. A guide channel is formed between the guide slopes 313 of the two guide strips 312. The distance between the two guide strips 312 corresponds to the width of the battery box 40. The guide channel tends to expand outwards in the opening direction of the battery cavity 11. The guide strips 312 guide and limit the battery box 40. When the battery box 40 is pushed into the battery cavity 11, the guide channel gradually contracts in the pushing direction, guiding and positioning the battery box 40.

[0055] In some possible embodiments, the side of the receiving groove 311 adjacent to the opening of the battery cavity 11 is a buffer slope. When the rolling element 44 moves above the buffer slope, the rolling element 44 rolls in cooperation with the buffer slope. The inclination angle of the buffer slope can be 10°, 30°, etc., so that the rolling element 44 can enter the receiving groove 311 relatively slowly, preventing the battery box 40 from being damaged by impact. When the battery box 40 needs to be removed for maintenance, the buffer slope forms a ramp, which also helps to pull the battery box 40 out when it is pulled outward.

[0056] Please see Figures 4 to 6 In some possible embodiments, the battery box 40 includes a box body 41, battery cells, and a bottom shell 42. The box body 41 has a receiving cavity for accommodating the batteries; multiple battery cells are respectively disposed in the receiving cavity, and the battery cells are electrically connected to electrical components; the bottom shell 42 is disposed at the bottom of the box body 41, and a flow channel is formed on one side of the bottom shell 42 that fits against the box body 41. The flow channel and the bottom surface of the box body 41 form a liquid cooling flow channel. The liquid cooling flow channel has a tortuous design, and the inlet and outlet of the liquid cooling flow channel are respectively connected to a cooling unit through cooling pipes to cool the battery cells using circulating coolant. A rolling element 44 is disposed on the bottom shell 42. When the bottom shell 42 is relatively thin, reinforcing plates 43 can be provided on both sides of the bottom shell 42. The rolling element 44 is embedded in the mounting groove of the reinforcing plate 43, and the reinforcing plate 43 and the bottom shell 42 are fixed together by welding or screws.

[0057] Please see Figure 7 and Figure 8 In some possible embodiments, the bottom of the cabinet 10 is provided with a bracket 14, and the bracket 14 has a through transfer groove 141 in the horizontal direction. At least two transfer grooves 141 are provided on the side of the bracket 14 to facilitate the transfer of the energy storage cabinet or cabinet 10 using a forklift. Multiple transfer grooves 141 are arranged in parallel. A sealing plate 15 is provided on the side of the bracket 14, covering the opening of the transfer groove 141 and detachably connected to the bracket 14. After the energy storage cabinet is installed, the sealing plate 15 is used to block the transfer groove 141 to prevent debris or animals from entering the interior of the bracket 14. The sealing plate 15 and the bracket 14 are detachably connected, specifically by screw connection, plug-in connection, magnetic fixation, or other methods.

[0058] Please see Figure 1 In some possible embodiments, the top of the cabinet 10 is provided with a lifting ring 16 to facilitate the crane to lift it to the installation position.

[0059] Please see Figure 3 In some possible embodiments, the battery box 40 has a first mounting hole 431, and the support unit has a second mounting hole 314 corresponding to the first mounting hole 431. Bolts can be installed in the first mounting hole 431 and the second mounting hole 314 to fix the battery box 40 and the support unit together.

[0060] Please see Figure 1 In some possible embodiments, the cabinet door 20 is rotatably connected to the cabinet body 10. The cabinet body 10 is provided with sealing strips 17 around the opening of the battery cavity 11 and the opening of the electrical cavity 12, respectively. The cabinet door 20 is used to abut against the sealing strips 17. The sealing strips 17 are existing silicone sealing strips 17. The cabinet door 20 has good sealing performance after being closed and can be waterproof and dustproof.
