Description

Technical Field

[0001] This utility model relates to the field of energy storage system technology, specifically to an AC-DC module that supports RJ45 four-way connection. Background Technology

[0002] An Uninterruptible Power Supply (UPS) is a type of power supply that includes an energy storage device. It is primarily used to provide uninterrupted power to equipment with high power stability requirements. When the mains input is normal, the UPS stabilizes the mains voltage and supplies it to the load. In this state, the UPS functions as an AC voltage regulator while simultaneously charging its internal battery. When the mains power is interrupted (power outage), the UPS immediately switches from the battery's DC power to the load via an inverter, continuing to supply 220V AC power to maintain normal operation and protecting the load's hardware and software from damage.

[0003] To achieve the above functions, a UPS system typically requires a Battery Management System (BMS) and battery packs. The battery packs are connected to the BMS, which controls their charging and discharging. In some cases, a display device is mounted on the battery cabinet, connected to the BMS via an RJ45 network cable to collect and display the various operational statuses of the battery packs as monitored by the BMS. The BMS usually requires an external DC power supply.

[0004] However, in actual implementation, the inventors found that some projects only have one 220V AC input when deployed. When multiple battery cabinets are deployed, such as three, and each battery cabinet has a battery management system, the power supply becomes relatively complex, requiring the use of power strips for switching and setting up multiple DC power supplies. Correspondingly, if a display device is required in such cases, three display devices are often needed. These factors lead to a large number of complex wiring harnesses in the energy storage system.

[0056] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0057] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0058] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0059] This utility model includes:

[0060] An AC-DC module that supports RJ45 quad-channel, such as Figure 1-3 As shown, it includes a housing 1;

[0061] An AC input port 11 is provided on the first end of the housing 1;

[0062] Multiple DC output ports 12 are provided on the second end of the housing 1;

[0063] A rectifier transformer module 3 is installed inside the housing 1;

[0064] The module input terminal 31 of the rectifier transformer module 3 is connected to the AC input port 11;

[0065] The module output terminal 32 of the rectifier transformer module 3 is connected to the DC output port 12 respectively;

[0066] A first opening is provided on the first panel of the housing 1;

[0067] A four-port network assembly 4 is installed at the first opening.

[0068] Specifically, in response to the problem that existing energy storage systems with multiple battery cabinets require numerous display devices, DC power supplies, and wiring harnesses, this solution provides an AC-DC module that supports RJ45 four-way connection. The housing 1 of this AC-DC module integrates a rectifier transformer module 3, which contains a corresponding rectifier transformer circuit for converting a 220V AC input into a DC output of a specific voltage.

[0069] Taking a power supply scenario with three power management systems as an example, the rectifier-transformer module 3 has three module output terminals 32. The circuit in the rectifier-transformer module 3 includes a transformer to convert the AC input voltage to a lower voltage. A rectifier circuit is set after the transformer to convert the AC power to the DC bus. Three DC-DC circuits are set on the DC bus to supply power according to the power requirements of the subsequent stages. The output terminal of each DC-DC circuit is connected to one module output terminal 32. The module output terminal 32 is connected to the DC output port 12 through cables, and the DC output port 12 is then connected to the battery management system through corresponding wiring harnesses.

[0070] In another embodiment, the processing may also be performed using a DC-DC circuit with three pairs of terminals at the output.

[0071] Furthermore, in the prior art, since the display device collects and displays data by connecting to the battery management system via an RJ45 network cable, in order to reduce the number of devices, in this embodiment, a quad-connection port component 4 is also integrated in the remaining space of the housing 1. This quad-connection port component is a device similar to a router, which can realize simple networking of accessed Ethernet devices and assign IP addresses. The battery management system and the display device can exchange data in this network.

[0072] In one embodiment, the housing 1 is rectangular parallelepiped;

[0073] The first end and the second end of the housing 1 are located at the two ends of the long axis of the housing 1, respectively;

[0074] The rectifier transformer module 3 is located in the middle of the housing;

[0075] AC input port 11 and DC output port 12 are respectively located on the end plates at both ends;

[0076] A protruding stud 13 is provided on the inner side of the back plate of the housing 1 at the position corresponding to the rectifier transformer module 3;

[0077] The rectifier transformer module 3 is mounted on the housing via studs 13.

[0078] Specifically, to achieve a more compact device size, this embodiment includes a hollow rectangular housing 1. The middle portion of the housing 1 is used to install the rectifier transformer module 3, with the ends left open for wiring. A stud 13 is provided in the middle portion, with a screw hole at the top of the stud 13. A corresponding mounting hole is also provided on the rectifier transformer module 3, and screws are screwed into the screw hole for fixation.

[0079] Furthermore, the housing 1 mainly consists of a back panel and a first front panel. The first front panel is 7-shaped, and the back panel is roughly a rectangular cube with the front panel and a top side panel removed. Mounting holes are provided at the corresponding interface positions. The first front panel is fitted onto the back panel of the housing and secured with screws. During installation, the first front panel is removed and the rectifier transformer module 3 is installed, secured, and wired. The grid connection assembly 4 is installed on the back of the first front panel, and then the first front panel and the back panel are combined.

[0080] In one embodiment, such as Figure 4 As shown, the rectifier-transformer module 3 includes:

[0081] Circuit board 33 is mounted on transformer base plate 34;

[0082] The containment vessel 35 has a portal-shaped structure and is mounted on the transformer base plate 34.

[0083] The containment 35 has openings at both ends along its long axis;

[0084] The module input terminal 31 and the module output terminal 32 are located outside the opening;

[0085] The containment vessel 35 has openings.

[0086] Specifically, in order to achieve better equipment safety, in this embodiment, a rectangular transformer base plate 34 is first set up. A circuit board 33 is installed on the top of the transformer base plate 34 by screwing screws into the mounting holes. A rectifier and transformer circuit is set on the circuit board 33.

[0087] Since rectifier transformer circuits typically contain large discrete components, such as transformers and capacitors, a safety enclosure 35 with a certain height is provided. The safety enclosure 35 surrounds the circuit board 33 and houses all the components, preventing the components from being damaged by collisions with other parts inside the enclosure 1.

[0088] The containment housing 35 has openings to provide some heat dissipation for the internal components while reducing weight. Additionally, the containment housing 35 has openings at both ends along its long axis, with the module input terminal 31 and module output terminal 32 located outside the openings for easy wiring.

[0089] In one embodiment, the module output terminal 32 includes a module positive output terminal 321 and a module negative output terminal 322;

[0090] The module's positive output terminal 321 and negative output terminal 322 are each a one-to-three terminal conversion;

[0091] The positive output terminal 321 and the negative output terminal 322 of the module are arranged horizontally.

[0092] Specifically, to achieve a more compact device size, in this embodiment, after the DC-DC circuit processing is completed, two 1-to-3-terminal converters are respectively provided on the positive and negative sides of the output terminal as the module's positive output terminal 321 and module negative output terminal 322, and arranged horizontally. During wiring, the positive and negative wires of each DC output port 2 are respectively connected to a set of module positive output terminals 321 and module negative output terminals 322.

[0093] In one embodiment, the network port component 4 and the module output terminal 32 are stacked together;

[0094] The grid port assembly 4 is located on the side closer to the front of the housing;

[0095] The network port assembly 4 is fixed to the housing via the network port assembly bracket 41;

[0096] The network port component bracket 41 is shaped like a "Z".

[0097] The network port component bracket 41 has screw holes on its two feet, which are used to fix it to the housing 1.

[0098] Specifically, in order to achieve a more compact device size, in this embodiment, after setting the horizontal module output end 32, a network port component 4 is set based on the space above the module output end 32. This avoids the network port component 4 being pressed down after the first panel is assembled, which would cause the wire harness on the right side of the module output end 32 to be compressed and cause a fault. At the same time, a compact device size is achieved.

[0099] The network port component 4 is rectangular and has multiple network cable interfaces. In the above embodiment with one display device and three battery management systems, the number of network cable interfaces is four, all of which are RJ45 network ports.

[0100] The network cable interface is exposed at the first opening. The long axis of the parallel port assembly coincides with the short axis of the housing, and the network cable interfaces are arranged sequentially along the long axis of the parallel port assembly.

[0101] A network port assembly bracket 41 is provided on the back of the short axis of the network port assembly 4. The network port assembly bracket 41 is shaped like a "Z". The concave part is used to fit on the back of the network port assembly 4. The two legs extend upward to the side of the network port assembly 4 near the network cable interface. Screw holes are provided on the bottom surface of the two legs, which are fixed in place with the corresponding holes on the first panel of the housing 1.

[0102] In one embodiment, a hook 5 is provided on the back of the housing 1. The hook 5 is in the shape of a "Z". The long side of the hook 5 is fixed to one side of the back plate of the housing 1. The long side extends upward to the device and passes over the back of the housing 1. Then it moves laterally to the back and extends a certain length before turning downward to form a hook. The hook 5 can be hung on the crossbeam of the battery cabinet for easy fixation.

[0103] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
