Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and more specifically to an AC / DC integrated high-voltage box control box and energy storage cabinet. Background Technology

[0002] A battery cluster is the core unit of an energy storage system or power battery pack, playing a crucial role in the era of clean energy. The main components of a battery cluster are: several battery pack enclosures, a high-voltage box (HVB), a low-voltage distribution box, a power conversion system (PCS), and an energy management system (EMS) communication system.

[0003] In energy storage systems, the high-voltage distribution box is a key power distribution device connecting the battery pack and the inverter / PCS, and mainly undertakes three core functions: high-voltage power distribution, safety protection, and system monitoring; the low-voltage distribution box plays a significant role in power distribution, circuit protection, and operation monitoring.

[0004] The existing high-voltage distribution box is a single component, and the low-voltage distribution box is also designed as a separate component. That is, the high-voltage box and the low-voltage distribution box are integrated into separate boxes within an integrated cabinet, or directly and separately integrated into an industrial / commercial integrated cabinet. Dividing them into two components occupies more internal space in the industrial / commercial integrated cabinet, resulting in a larger cabinet size; dividing them into two components leads to many fragmented communication and power supply wires inside the cabinet, which can become very messy if not handled properly; it is inconvenient for customers to connect wires, requiring the removal of various panels and understanding of internal terminal views; it is difficult to make the cabinet compact, resulting in an unsightly cabinet design, and the increased number of components increases various costs.

[0005] For those skilled in the art, how to reduce the space occupied by high-voltage boxes and low-voltage distribution boxes is a technical problem that needs to be solved. Utility Model Content

[0006] The core of this utility model is to provide an integrated AC / DC high-voltage control box, which integrates the DC module and the AC module into the same enclosure component, realizing integrated AC and DC configuration, reducing space occupation, and achieving higher integration. The specific solution is as follows:

[0007] A high-voltage control box integrating AC and DC includes a box assembly, a DC module and an AC module. The DC module is installed at the front of the inner cavity of the box assembly, and the AC module is installed at the rear of the inner cavity of the box assembly. There is an electrical gap between the DC module and the AC module.

[0008] The front panel of the enclosure assembly is provided with several interfaces, and the rear panel and the rear of the side wall of the enclosure assembly are provided with several interfaces.

[0009] Optionally, the DC module includes a DC unit, a main control unit, a diode, a switching power supply, a surge protector fuse, a relay assembly, fuse terminals, a surge protector, and communication terminals;

[0010] The relay assembly, the fuse terminal, and the surge protector are located in the middle of the enclosure assembly.

[0011] Optionally, the DC module includes a water immersion sensor disposed in the middle of the housing assembly.

[0012] Optionally, the AC module includes an AC unit, a circuit breaker, and an electricity meter assembly.

[0013] Optionally, the AC unit includes four sets of copper busbars, each set of copper busbars being provided with an AC input terminal and an AC output terminal.

[0014] Optionally, the AC output terminal is a gland connector.

[0015] Optionally, the front panel and the rear panel can be detachably installed on the side wall, and a sealing strip is provided to achieve a seal.

[0016] Optionally, the front panel is provided with a front communication interface, a high-voltage DC input interface, a high-voltage DC output interface, a high-voltage DC switch, an AC power supply interface, an AC external power supply interface, and an input network port.

[0018] This utility model also provides an energy storage cabinet, including the AC / DC integrated high-voltage box control box described in any of the above-mentioned claims.

[0019] This utility model provides an integrated AC / DC high-voltage control box. A DC module and an AC module are installed inside the box assembly. The DC module is installed at the front of the box assembly's inner cavity, and the AC module is installed at the rear. By placing the DC and AC modules within the same box assembly, the structure is compact and the layout is reasonable, achieving high-voltage and low-voltage integration. Compared to using two separate boxes, this reduces space occupancy. Furthermore, there is electrical separation between the DC and AC modules, preventing interference between them. The DC module's wiring harness is mainly led out from the front panel of the box assembly, while the AC module's wiring harness is mainly led out from the rear panel and the rear of the side wall of the box assembly. Separate AC and DC wiring ensures a neat and aesthetically pleasing appearance and high safety. Attached Figure Description

[0033] This utility model discloses an integrated AC / DC high-voltage control box, comprising a housing assembly 10, a DC module 20, and an AC module 30. The housing assembly 10 forms the outer shell of the entire integrated AC / DC high-voltage control box, and its interior has cavities to accommodate various components. The housing assembly 10 typically adopts a cuboid cavity structure, including a front panel 101, a rear panel 102, and four side walls 103. The four side walls together form a cylindrical structure, with the front panel 101 and rear panel 102 respectively encapsulated at both ends of the cylindrical structure. Figure 1 As shown, the box assembly 10 has its length along the Y-axis, its width along the X-axis, and its height along the Z-axis. The entire box assembly 10 extends along the Y-axis, with its length dimension greater than its width dimension and its height dimension, forming a slender, elongated rectangular cavity structure. It should be noted that the box assembly 10 can also adopt other external shapes; for example, the sidewall 103 can be a curved surface structure. These forms should all be included within the scope of protection of this utility model.

[0034] The housing assembly 10 extends along its length along the Y-axis, and is distinguished as front and rear along this length direction, such as... Figure 1 As shown, the positive direction of the Y-axis is forward, and the negative direction is backward. Of course, the distinction between forward and backward is only for the structural distinction shown in the attached diagram and does not represent the forward and backward direction of the AC / DC integrated high-voltage control box in actual use.

[0035] A DC module 20 and an AC module 30 are installed inside the enclosure assembly 10. Each DC module 20 and AC module 30 contains several components. The DC module 20 is installed at the front of the enclosure assembly 10, and the AC module 30 is installed at the rear of the enclosure assembly 10. Specifically, the DC module 20 is closer to the front of the enclosure assembly 10 than the AC module 30, and the AC module 30 is closer to the rear of the enclosure assembly 10 than the DC module 20. The DC module 20 and AC module 30 each occupy approximately half the space of the enclosure assembly 10. Figure 2 The area below the dashed line L is the boundary, and the area above the dashed line L is mainly equipped with the various components of the DC module 20, while the area above the dashed line L is mainly equipped with the various components of the AC module 30.

The components of the AC module 30 are mainly electrically connected to the outside world through the interfaces provided on the rear panel 102 and the rear of the side wall 103.

[0038] This utility model's integrated AC / DC high-voltage control box integrates the DC module 20 and the AC module 30 within the same enclosure assembly 10. Compared to placing them in two separate enclosures, the single enclosure assembly 10 has a smaller spatial dimension, reducing space occupation and allowing for good compatibility with energy storage cabinets of various sizes. The integrated AC / DC high-voltage control box arranges the DC module 20 and AC module 30 in a front-to-back direction, forming an electrical separation. This results in a compact structure, reasonable layout, separate AC and DC wiring, neat and aesthetically pleasing design, and high safety.
