Description

Technical Field

[0001] This utility model relates to the field of new energy batteries, and in particular to a high-voltage electrical component and an energy storage box. Background Technology

[0002] With the continuous deployment and mass production of larger capacity energy storage boxes, how to make more rational use of existing effective space and achieve greater battery capacity without increasing the size of existing energy storage boxes requires not only increasing the size and energy density of battery cells, but also continuously optimizing the existing space size of the boxes and the internal layout of the boxes themselves.

[0003] In existing technologies, the high-voltage electrical components in traditional energy storage boxes, such as the high-voltage maintenance switch (MSD), main positive and main negative connectors, and fuses, are fixed in different locations and using different methods. This design has three disadvantages: First, the MSD socket and the main positive and main negative sockets require separate molds and need to be fixed separately to the machined maintenance panel; second, the fuses need to be fixed to the bracket inside the box, which is inconvenient for subsequent maintenance; and third, it increases the installation process and tooling required for production, affecting production efficiency.

[0004] The existing high-voltage electrical components are installed and fixed separately, which makes the assembly of the junction box complicated and the production efficiency low. Utility Model Content

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the first panel structure provided in an embodiment of the present utility model; Figure 2 This is a schematic diagram of the second panel structure provided in an embodiment of the present utility model; Figure 3 This is an exploded schematic diagram of the high-voltage electrical component provided in this embodiment of the utility model; Figure 4 This is an exploded view of the high-voltage electrical assembly provided in this embodiment of the present invention. Figure 5 This is a schematic diagram of the energy storage box structure provided in an embodiment of this utility model. Figures 1 to 5 The high-voltage electrical component shown includes: a high-voltage electrical component integrated panel 1, on which a high-voltage maintenance switch 2, a main positive plug 3, a main negative plug 4 and a fuse 5 are disposed. The high-voltage electrical component integrated panel 1 has a first panel 11 and a second panel 12 opposite to each other. The high-voltage maintenance switch 2, the main positive plug 3 and the main negative plug 4 are inserted into the first panel 11, and the fuse 5 is disposed on the second panel 12.

[0026] For example, in this embodiment of the present invention, when the high-voltage electrical component integrated panel 1 is installed on the energy storage socket box, the first panel 11 is arranged facing outwards and the second panel 12 is arranged facing inwards, so that the fuse 5 is installed inside the energy storage socket box and connected to other internal components, and the high-voltage maintenance switch 2, the main positive plug 3, and the main negative plug 4 are exposed outside the energy storage socket box, facilitating maintenance operations. By centrally arranging the high-voltage maintenance switch 2, the main positive plug 3, the main negative plug 4, and the fuse 5 on the high-voltage electrical component integrated panel 1, when repairing or maintaining each high-voltage component, only the high-voltage electrical component integrated panel 1 needs to be removed for operation. Compared with the traditional technology of installing each high-voltage component in different positions in the energy storage socket box, the present embodiment of the present invention centrally installs the high-voltage components on the high-voltage electrical component integrated panel 1, which allows multiple high-voltage electrical component sockets to be molded separately and combined into one mold, reducing the mold cost of multiple parts and thus reducing the cost of parts. The high-voltage maintenance panel of the socket box in the traditional technology is a machined product, but in this embodiment, it is changed to a molded part, which can reduce development costs. The fuse 5, which was originally fixed to the internal bracket of the socket box, is now installed on the high-voltage electrical component integrated panel 1, which can reduce the cost of the bracket.

[0027] This utility model provides a high-voltage electrical component and energy storage box. By integrating the high-voltage maintenance switch 2, the main positive plug 3, the main negative plug 4, and the fuse 5 onto the high-voltage electrical component integrated panel 1, the high-voltage components can be centrally operated when they are installed on the energy storage box. This eliminates the need to fix the high-voltage components separately to the machined maintenance panel, saving assembly time and improving assembly efficiency. It effectively solves the problems of complex operation and low production efficiency in the prior art.

[0028] Optionally, the first panel 11 is provided with an MSD socket 111, and the high-voltage maintenance switch 2 is plugged into the MSD socket 111.

[0029] For example, in this embodiment of the present invention, the MSD socket 111 provides an installation base for the high-voltage maintenance switch 2. The MSD socket 111 can be integrally cast onto the high-voltage electrical component integrated panel 1. The MSD socket 111 manufactured in this way can reduce the setting of individual parts, reduce production costs, and improve assembly efficiency, thereby further improving the production efficiency of this component.

[0030] Optionally, the first panel 11 is provided with a main positive socket 112 and a main negative socket 113, the main positive plug 3 is plugged into the main positive socket 112, and the main negative plug 4 is plugged into the main negative socket 113.

[0031] For example, in this embodiment of the present invention, the main positive socket 112 provides an installation base for the main positive plug 3, and the main negative socket 113 provides an installation base for the main negative plug 4. The main positive socket 112 and the main negative socket 113 can be integrally cast onto the high-voltage electrical component integrated panel 1. The main positive socket 112 and the main negative socket 113 manufactured in this way can reduce the setting of individual parts, reduce production costs, and improve assembly efficiency, thereby further improving the production efficiency of this component.

[0032] Optionally, it also includes a fuse fixing bolt 6, a fuse fixing threaded hole 121 is provided on the second panel 12, a support lug 51 is provided on the fuse 5, and a mounting hole 511 matching the fuse fixing threaded hole 121 is provided on the support lug 51. The fuse fixing bolt 6 passes through the mounting hole 511 and is threadedly connected to the fuse fixing threaded hole 121.

[0033] For example, in this embodiment of the present invention, the fuse 5 is provided with lugs 51 on both sides, and mounting holes 511 are provided on the lugs 51. The fuse fixing bolts 6 pass through the mounting holes 511 and are threadedly connected to the fuse fixing threaded holes 121, which facilitates the installation and removal of the fuse 5. When the fuse 5 blows due to excessive current in the circuit, it needs to be replaced. The used fuse 5 can be removed by simply removing the fuse fixing bolts 6, and then a new fuse 5 can be installed for operation. By setting this structure, the operation is simple and the ease of operation of this component is improved.

[0034] Optionally, a plurality of panel fixing bolts 114 are provided on the first panel 11, and the plurality of panel fixing bolts 114 are arranged along the periphery of the first panel 11.

[0035] For example, in this embodiment of the present invention, a panel fixing bolt 114 is provided on the first panel 11 to securely install the high-voltage electrical component integrated panel 1 onto the energy storage box, thereby improving the structural stability of the component. Furthermore, since the first panel 11 faces outwards, the panel fixing bolt 114 on the first panel 11 facilitates the disassembly or installation of the high-voltage electrical component integrated panel 1, further enhancing the ease of operation of the component.

[0036] An energy storage box includes the aforementioned high-voltage electrical component, and also includes a box body 7 and a box cover 8. The box cover 8 has a box-shaped structure and is placed on the box body 7. A mounting groove 81 matching the high-voltage electrical component integrated panel 1 is provided on one side of the box cover 8. The high-voltage electrical component integrated panel 1 is mounted on the box cover 8 through the mounting groove 81.

[0037] Exemplarily, in this embodiment of the present invention, the housing 7 and the cover 8 provide protection for the battery cell and internal electronic components. By creating a mounting groove 81 on the cover 8, the high-voltage electrical component integrated panel 1 can be installed in conjunction with the mounting groove 81. Panel fixing bolts 114 can be used to install the high-voltage electrical component integrated panel 1 onto the cover 8, with the first panel 11 facing outwards and the second panel 12 facing inwards. This allows the fuse 5 to be connected to other internal electronic components, while the high-voltage maintenance switch 2 is exposed on the outside, facilitating its operation to disconnect the circuit. This structure improves the ease of operation of the energy storage box.

[0038] Optionally, an explosion-proof valve 9 is provided on the cover 8, and the explosion-proof valve 9 is located on one side of the high-voltage electrical component integrated panel 1.

[0039] For example, in this embodiment of the invention, the root cause of thermal runaway in the battery cell is the accumulation of heat due to exothermic side reactions within the cell. The rate of heat exchange between the cell and the outside is less than the rate of heat accumulation, causing the temperature to rise continuously until it reaches the ignition point, leading to combustion and explosion. To prevent thermal runaway accidents and avoid pressure imbalances within and outside the battery structure, and considering that lithium batteries instantly produce large amounts of toxic gases when they catch fire, timely and directional pressure relief and gas release are necessary. The explosion-proof valve 9 can achieve the requirements of maintaining pressure balance inside and outside the energy storage box and directional gas release, serving as a passive safety protection measure to prevent thermal runaway in the battery system. By setting the explosion-proof valve 9, the safety performance of this energy storage box is improved.

[0040] Optionally, the top of the cover 8 is provided with ventilation holes 82.

[0041] For example, in this embodiment of the present invention, by providing heat dissipation holes 82, heat exchange between the inside and outside of the energy storage box can be accelerated, preventing safety hazards caused by excessive internal temperature of the energy storage box. By providing heat dissipation holes 82, the heat dissipation performance of the energy storage box is improved.
