[0002] An uninterruptible power supply (UPS) is a power supply with voltage and frequency stabilization functions. When the mains power supply is interrupted, the UPS can ensure the continuity of the output power supply. The existing uninterruptible power supply includes a battery module, a power distribution module and an uninterruptible power supply module.

[0009] Furthermore, it also includes a battery control unit; the battery terminal includes a high-current part and a low-current part, and the hot-plug connector also correspondingly includes a high-current part and a low-current part. When the hot-plug connector is plugged into the battery terminal, the high-current part and the low-current part of the two are connected correspondingly; the high-current part of the hot-plug connector is connected to the busbar, and its low-current part is connected to the battery control unit.

[0010] Furthermore, each of the battery modules is stacked in the up-down direction and arranged in at least one column in the left-right direction, and a mounting backplane is provided corresponding to each column of the battery modules; each of the mounting backplanes is provided with the hot-swappable connector, and the busbar is fixedly installed on one of the mounting backplanes.

[0012] Furthermore, the battery control unit includes an address board and a control board, the hot-swappable connector is connected to the address board, the address board is connected to the control board, and the control board is connected to the integrated communication terminal.

[0013] Furthermore, it also includes an insulating plate, which is fixed to the mounting back plate and is located behind the mounting back plate to shield the hot-plug connectors, the busbar and the battery control unit.

[0014] In addition, the utility model also provides a power supply system, which includes a load and a power supply device as described in any one of the above items, wherein the input end of the power supply device is connected to a power source, and the output end is connected to the load.

[0015] From the above description of the utility model, it can be seen that compared with the prior art, the utility model has the following beneficial effects:

[0016] The power supply device provided by the utility model is provided with a hot-plug connector, through which the electrical components in the cabinet can be quickly disassembled and assembled. When disassembling and installing the electrical components, there is no need to connect them through cables, but they can be connected directly by plugging, and the subsequent wiring can be completed by the hot-plug connector;

[0017] At the same time, the utility model inventor also found that when using hot-plug connectors for hot-plug connections, the position of the hot-plug connectors needs to be fixed relative to the cabinet. If each hot-plug connector is fixed independently, the assembly efficiency will be reduced and positioning deviations will easily occur during assembly, resulting in the hot-plug connectors and the battery terminals of the electrical components being unable to be correctly plugged in.

[0018] To this end, the utility model further provides a mounting backplane in the wiring assembly of the power supply device. Before installing the electrical assembly, each hot-plug connector is first fixedly mounted on the mounting backplane according to a predetermined position, and then the mounting backplane is installed on the cabinet. At this time, the position of each hot-plug connector relative to the cabinet is determined. At the same time, since the hot-plug connector is pre-installed, when the hot-plug connector is installed on the cabinet, it is only necessary to install the mounting backplane, thereby improving the assembly efficiency; at the same time, the assembly accuracy between the mounting backplane and the hot-plug connector is high. Pre-installing the hot-plug connector on the mounting backplane can ensure that the installation position of each hot-plug connector and the electrical assembly is accurately corresponding, thereby ensuring that the hot-plug connector and the wiring terminals of the electrical assembly can be correctly plugged in.

[0019] In addition, the electrical components of the power supply device include a battery module, and the power supply device also includes an uninterruptible power supply module and a power distribution module. The power distribution module connects the battery module and the uninterruptible power supply module, and is connected to an external power supply and a load. The uninterruptible power supply module plays a role in adjusting the voltage, and the power distribution module plays a role in controlling the power supply device to charge through an external power supply or supply power to the load. Among them, hot-swappable connectors are mainly configured for the uninterruptible power supply module and the battery module, which can improve the efficiency of disassembly and assembly of the uninterruptible power supply module and the battery module.

[0020] Among them, the installation backplane is set at the rear of the battery module, and the battery terminal on the back of the battery module is connected through a hot-swappable connector, which makes it easy to disassemble and install the battery module. At the same time, the distribution module and the uninterruptible power supply module are seldom disassembled and installed repeatedly after installation. Therefore, the distribution module and the uninterruptible power supply module can be connected to the battery module through wires, which can avoid the installation backplane completely covering the rear of the entire cabinet, making it convenient for the cabinet to be connected to the outside.

[0021] At the same time, the utility model inventor discovered that when using the above structure to implement hot-swappable battery modules, due to the addition of an installation backplane, the external wiring of the hot-swappable connector can only bypass the installation backplane, which limits the wiring compared to the case where no backplane is installed.

[0022] To this end, the utility model arranges a busbar on the installation backplane, and the strong current of each battery module can be first connected in parallel to the busbar, and then individually connected to the distribution module and / or the uninterruptible power supply module through the busbar. In this way, each battery module only needs to be wired within the range of the installation backplane, and there is no need to independently connect the wires to the distribution module and / or the uninterruptible power supply module for each battery module. The overall wiring is simpler, and the wiring path from the battery module to the busbar is short, which can reduce losses and the probability of failure. By connecting the busbar and the distribution module and / or the uninterruptible power supply module through a single wire, the number of wiring terminals on the distribution module and / or the uninterruptible power supply module can be reduced, thereby reducing costs and improving wiring efficiency.

[0023] A battery control unit is provided to monitor each battery module.

[0024] The battery modules are stacked up and down and can be arranged to form multiple columns. Each column of battery modules is equipped with a corresponding mounting backplane. Through the hot-swappable connectors on the corresponding mounting backplane, the battery modules in each column can be quickly disassembled and wired.

[0025] At the same time, integrated communication terminals and external communication terminals are set. The weak current parts of the battery control unit, distribution module and uninterruptible power supply module can be integrated and connected to the integrated communication terminals, and then connected to the external communication terminals through the integrated communication terminals. The external communication terminals can be conveniently connected to external communication cables.

[0026] An insulating plate is provided to cover the hot-plug connectors and busbars in the wiring assembly to prevent the strong electricity in the cabinet from being touched during inspection and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0064] The power supply device provided in this embodiment is provided with a hot-swap connector 32, through which the battery module 20 can be quickly disassembled and assembled. When disassembling and installing the battery module 20, there is no need to connect the battery module 20 through cables, but it can be directly connected by plugging, and the subsequent wiring can be completed through the hot-swap connector 32. At the same time, a mounting backplane 31 is also provided in the wiring assembly 30 of the power supply device. Before installing the battery module 20, each hot-swap connector 32 is first fixedly installed on the mounting backplane 31 according to a predetermined position, and then the mounting backplane 31 is installed to the cabinet 10. At this time, the position of each hot-plug connector 32 relative to the cabinet 10 is determined. At the same time, since the hot-plug connector 32 is pre-installed, when the hot-plug connector 32 is installed on the cabinet 10, it is only necessary to install the mounting backplane 31, thereby improving the assembly efficiency; at the same time, the assembly accuracy between the mounting backplane 31 and the hot-plug connector 32 is high. Pre-installing the hot-plug connector 32 on the mounting backplane 31 can ensure that the installation position of each hot-plug connector 32 and the battery module 20 accurately corresponds, thereby ensuring that the hot-plug connector 32 and the battery terminal 21 can be correctly plugged in.
