Description

Technical Field

[0001] This utility model belongs to the field of energy storage battery system technology, specifically relating to a safe and convenient internal maintenance structure for the front of a PACK. Background Technology

[0002] In energy storage systems, once the PACK (battery module) is installed in an integrated energy storage cabinet or container, the maintenance of some vulnerable components installed inside the PACK becomes a rather tricky issue. The main function of the fuse is to protect the circuit from damage caused by short circuits and overcurrents, while the main function of the BMU (battery management unit) is to monitor and manage various parameters such as battery voltage and temperature. Both the fuse and the BMU are the main components inside the PACK that need to be replaced.

[0003] However, the current BMU and fuse packs are not designed for easy replacement, and common similar products have the following shortcomings:

[0004] (1) There is no maintenance window on the front. The BMU is directly installed on the outside of the front panel, which will result in the internal and external connection harnesses being directly exposed on the outside of the front of the PACK. This will affect both the aesthetics of the front of the PACK and its IP protection level. The lack of internal fuses also means that the PACK has one less layer of safety protection.

[0005] (2) There is no maintenance window on the front. The BMU is installed directly behind the front panel and the fuse is installed inside the PACK. This means that after the PACK is installed, if the BMU, fuse, etc. are damaged or blown, it will be impossible to replace or maintain them from the front.

[0006] (3) There is a maintenance window on the front. The BMU is located within the maintenance window. The fuse is installed inside the PACK but is not within the maintenance window. In case the fuse is damaged or blown, it will be impossible to replace or maintain it from the front.

[0007] (4) There is a maintenance window on the front. The BMU and fuse are both located within the maintenance window. However, the fuse is installed vertically inside the PACK. Because the PACK is relatively compact, vertical installation will result in the inability of tools to enter the PACK if the fuse is damaged or blown. Even if it is entered, it is difficult to use tools to remove the fasteners of the fuse, thus making it impossible to perform front replacement and maintenance. There will also be safety hazards if hands and tools enter the PACK.

[0008] Therefore, it is very important to design a safe and convenient internal maintenance structure for the front of the PACK. Utility Model Content

[0009] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a safe and convenient internal maintenance structure for the front of the PACK.

[0010] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0011] A safe and convenient PACK front internal maintenance structure includes a mounting plate that is locked onto the front panel. The mounting plate has an integral recess, a fuse base is locked onto the mounting plate at the recess, and a battery management unit is locked onto the mounting plate.

[0012] A fuse is locked onto the fuse base, and a copper busbar is installed between the fuse base and the fuse.

[0013] The front panel has an opening with dimensions matching the mounting plate, and a sealing plate is installed at the opening on the front panel;

[0014] The fuse base is provided with two positioning posts. The side of the positioning post facing the recess is threaded with a locking screw and a nut. The fuse base is provided with a recess in the middle and an insulating plate is integrally connected to both sides of the fuse base.

[0015] Furthermore, the mounting plate is integrally connected to ear plates at both ends. Each ear plate has two fixing holes and one limiting hole. This design allows the limiting hole to help the mounting plate be quickly positioned in a designated location, while the two fixing holes ensure the installation strength of the mounting plate, thereby guaranteeing its supporting force.

[0016] Furthermore, sealing silicone foam is installed between the mounting plate and the front panel, as well as between the sealing plate and the front panel. This design allows the silicone foam to have excellent thermal insulation properties, effectively reducing heat exchange between the energy storage device and the external environment, maintaining stable internal temperature, and improving the overall thermal efficiency of the battery pack. It also provides excellent sealing performance, tightly fitting all components of the energy storage device, effectively preventing harmful substances such as air and moisture from entering the device, protecting critical components like batteries from damage, and extending the device's lifespan. Additionally, it has good shock absorption, absorbing and dispersing stress caused by vibration during transportation, installation, and use, reducing internal mechanical wear and fatigue damage, and improving the device's reliability and stability.

[0017] Furthermore, the sealing plate is fixed to the front panel by ten screws. This design allows for installation around the perimeter of the sealing plate, ensuring installation strength and sealing performance.

[0018] Furthermore, the positioning post is fitted with an epoxy pad. This design, with the epoxy pad being a high-performance insulating material, effectively isolates the battery components in the energy storage device, preventing electrolyte leakage and short circuits, and improving device safety.

[0019] The beneficial effects of using this utility model are as follows:

[0020] This utility model has a simple structure and is easy and quick to assemble and disassemble. Only a Phillips or socket screwdriver is needed to easily assemble and disassemble the BMU (Battery Management Unit) and fuses. It is not only a convenient internal maintenance structure for the front of the PACK, but also saves space inside the PACK. Furthermore, when assembling and disassembling fuses, there is no need to touch or adjust the position of the internal series copper busbars by hand, which further ensures the safety of installation and subsequent maintenance.

[0030] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] like Figs. 1-4 As shown, the present invention provides a safe and convenient PACK front internal maintenance structure, including a mounting plate 2 that is locked and installed on the front panel 1. The mounting plate 2 is integrally provided with a recessed opening 3. A fuse base 4 is locked and installed on the mounting plate 2 at the position of the recessed opening 3. A battery management unit 5 is locked and installed on the mounting plate 2.

[0032] A fuse 6 is locked onto the fuse base 4, and a copper busbar 7 is installed between the fuse base 4 and the fuse 6.

[0033] The front panel 1 has a through-hole 8 with a size matching the mounting plate 2, and a sealing plate 9 is installed on the front panel 1 at the through-hole 8;

[0034] The fuse base 4 is provided with two positioning posts 41. The side of the positioning post 41 facing the recess 3 is threaded with a locking screw 42. The positioning post 41 is threaded with a nut 43. The fuse base 4 is provided with a recess 44 in the middle position. The fuse base 4 is integrally connected with an insulating plate 45 on both sides.

[0035] In this implementation case, when using a safe and convenient PACK front internal maintenance structure, the fuse 6 is first installed on the fuse base 4. The recess 44 allows the fuse 6 to be installed lower, thereby reducing the space occupied by the fuse 6. The insulating plate 45 can effectively ensure the insulation distance of the live parts. With the effect of the locking screw 42, the fuse base 4 is firmly installed on the mounting plate 2. After using the positioning post 41 and the nut 43 to install the fuse 6 on the fuse base 4, the battery management unit 5 can be locked and installed on the mounting plate 2. After locking the fuse base 4 in the recess 3, the mounting plate 2 can be installed on the front panel 1 at the position of the through 8. Then, the through 8 is closed with the sealing plate 9 to complete the overall installation.

[0036] Copper busbar 7 ensures the transmission of electrical data;

[0037] With this structure, when maintenance is required, the cover plate 9 can be removed directly using a screwdriver to access the through-hole 8, where the fuse 6 and battery management unit 5 can be removed, which is simple, convenient and quick.

[0038] Preferably, the mounting plate 2 has ear plates 21 integrally connected to both ends. Each ear plate 21 has two fixing holes 22 and one limiting hole 23. This design allows the limiting hole 23 to assist in quickly positioning the mounting plate 2 at a designated location, while the two fixing holes 22 ensure the installation strength of the mounting plate 2, thereby guaranteeing its supporting force. However, a different positioning and fixing structure for the mounting plate 2 can also be considered depending on the specific circumstances.

[0039] Preferably, sealing silicone foam 10 is installed between the mounting plate 2 and the front panel 1, as well as between the sealing plate 9 and the front panel 1. This design allows the silicone foam to have excellent heat insulation performance, effectively reducing heat exchange between the inside and outside environment of the energy storage device, maintaining stable internal temperature, and improving the overall thermal efficiency of the battery pack. It also has excellent sealing performance, tightly fitting all components of the energy storage device, effectively preventing harmful substances such as air and moisture from entering the device, protecting critical components such as batteries from damage, and extending the service life of the device. Furthermore, it has good shock absorption, absorbing and dispersing stress caused by vibration during transportation, installation, and use, reducing mechanical wear and fatigue damage inside the device, and improving the reliability and stability of the device. In practice, sealing and heat insulation protection measures can also be considered depending on the specific circumstances.

[0040] The preferred sealing plate 9 is fixed to the front panel 1 with ten screws. This design allows for installation around the perimeter of the sealing plate 9, ensuring installation strength and sealing. In practice, the installation method of the sealing plate 9 can also be considered according to specific circumstances.

[0041] The preferred positioning post 41 is matched with an epoxy pad 11. With this design, the epoxy pad, as a high-performance insulating material, effectively isolates the battery components in the energy storage device, prevents electrolyte leakage and short circuit, and improves the safety of the device. In fact, safety protection measures can also be considered according to specific circumstances.

[0042] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
