Description

Technical Field

[0001] This invention relates to the field of battery technology, and in particular to a home energy storage lithium battery module that is easy to disassemble and maintain. Background Technology

[0002] Electricity is an energy source that uses electrical energy as its power source. It is a power production and consumption system composed of power generation, transmission, transformation, distribution, and consumption. It converts primary energy from nature into electricity through mechanical energy devices, and then supplies the electricity to users through transmission, transformation, and distribution. With the rapid development of my country's economy and the popularization of environmental protection concepts, many families will install home energy storage systems. The purpose is to use lithium batteries to store energy through solar energy or the grid, and use it at night or when the grid is down, reducing dependence on the grid. In order to optimize the user experience, a home energy storage lithium battery module that is easy to install, remove, and maintain is proposed.

[0003] The lithium batteries used in current home energy storage systems experience a gradual decline in lifespan over time. However, a home energy storage lithium battery module that is easy to disassemble and maintain, as disclosed in CN117239295B, is inconvenient to disassemble during battery maintenance, making lithium battery replacement quite troublesome. Therefore, we propose a home energy storage lithium battery module that is easy to disassemble and maintain to solve the aforementioned problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing lithium batteries, which are inconvenient to disassemble when they need to be replaced or repaired, and to propose a home energy storage lithium battery module that is easy to disassemble and maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-disassemble and maintain home energy storage lithium battery module includes a housing, a battery slot on the top of the housing, and a mounting slot on one side of the housing. Two U-shaped brackets are symmetrically fixed on the inner wall of the battery slot, and positioning slots are provided on the top of the U-shaped brackets. A handle is rotatably connected to the housing. The battery module also includes:

[0007] Multiple battery mounting mechanisms are symmetrically mounted on two U-shaped brackets. The U-shaped brackets are used to limit the battery mounting mechanisms, and lithium batteries are mounted on the battery mounting mechanisms.

[0008] A power connection mechanism is installed inside the battery compartment and is electrically connected to multiple battery mounting mechanisms. One side of the power connection mechanism extends into the mounting compartment.

[0009] The charging and discharging mechanism is installed in the mounting slot and is electrically connected to the power connection mechanism. The charging and discharging mechanism is used to charge multiple lithium batteries and output the power on the lithium batteries.

[0010] In one possible design, the battery mounting mechanism includes a battery bracket with two handles symmetrically fixedly mounted on its top. A heat exchange bracket is fixedly mounted inside the battery bracket, and the lithium battery is clipped into the battery bracket. The heat exchange bracket is used to support the lithium battery and dissipate the heat generated when the lithium battery is working. A U-shaped clip is fixedly mounted on the bottom of the battery bracket, and the bottom of the U-shaped clip extends into the positioning groove and engages with the inner wall of the positioning groove.

[0011] In one possible design, two heat exchange plates are symmetrically fixedly installed inside the U-shaped bracket, and the heat exchange plates are corrugated plates, with the heat exchange plates in contact with the corresponding heat exchange brackets.

[0012] In one possible design, two first contact plates are symmetrically fixedly installed on the inner wall of one side of the battery holder. The two first contact plates are electrically connected to the same metal transmission bar on the side close to each other. One side of the metal transmission bar is electrically connected to a contact post. One end of the contact post extends into the battery slot and is fixedly connected to a contact ring. The contact ring is electrically plugged into the contact mechanism. Two second contact plates are symmetrically electrically connected to one side of the lithium battery. The lithium battery is equipped with a charging module and a discharging module. The charging module and the discharging module are electrically connected to the two second contact plates respectively. The second contact plates are in electrical contact with the corresponding first contact plates.

[0013] In one possible design, the power connection mechanism includes a fixed frame fixedly installed in the battery compartment, a connecting plate fixedly installed in the fixed frame, a plurality of conductive rods symmetrically fixedly installed on the top of the connecting plate, the top ends of the plurality of conductive rods all penetrating the fixed frame and extending to the top of the fixed frame, the conductive rods being fixedly connected to the fixed frame, the conductive rods penetrating the corresponding power connection rings and being electrically connected to the power connection rings, and an L-shaped power transmission plate electrically connected to the bottom of the connecting plate, one side of the L-shaped power transmission plate extending into the mounting groove and being connected to the charging and discharging mechanism.

[0014] In one possible design, the charging and discharging mechanism includes a side cover plate fixedly installed at the opening of the mounting slot. A wire is fixedly installed through the side cover plate. A plug is fixedly installed at one end of the wire, and the other end of the wire is electrically connected to a rectifier. The rectifier is fixedly installed on the bottom inner wall of the mounting slot. A second resistor is electrically connected to the rectifier. The second resistor is used to block the direct current output by the lithium battery from flowing to the wire. The cathode of the second resistor is electrically connected to the L-shaped power transmission plate, and the anode of the second resistor is electrically connected to the rectifier.

[0015] In one possible design, the charging and discharging mechanism further includes a plug-in panel fixedly embedded in the side cover plate. An inverter is electrically connected to one side of the plug-in panel located in the mounting groove. A first resistor is electrically connected to the inverter. The anode of the first resistor is electrically connected to the L-shaped power transmission plate, and the cathode of the first resistor is electrically connected to the inverter.

[0016] In one possible design, a top cover is snapped into the opening of the battery slot, and two pressure plates are symmetrically fixed to the bottom of the top cover, with the pressure plates contacting the corresponding two battery brackets.

[0017] In this application, after placing the lithium battery in the battery holder, a U-shaped clip is inserted into the corresponding positioning slot to support and limit the lithium battery. Then, the top cover is snapped into the battery compartment. Two pressure plates at this point press and limit the four battery holders, preventing separation between the battery holders and the U-shaped holders and ensuring the lithium battery remains in a stable position without shaking. Furthermore, when the battery holder is snapped into the U-shaped holder, the connecting ring can connect to the corresponding conductive rod. Therefore, when outputting the electrical energy stored in the lithium battery, it can be transmitted through the conductive post, connecting ring, conductive rod, connecting plate, and L-shaped transmission plate to the first resistor. Current flowing through the first resistor can then be transmitted to the inverter, thereby converting DC power... The system converts AC power to DC power. After connecting household appliances to the power strip, it can supply power to the appliances. When charging is needed, the plug can be inserted into the external power strip, and the AC power can be transmitted to the rectifier through the wires. The rectifier converts the AC power to DC power, which is then transmitted through the second resistor to the L-shaped power supply board. After passing through the connecting board, multiple conductive rods, multiple power connection rings, and multiple conductive posts, it can simultaneously supply power to multiple lithium batteries, thus facilitating the charging of multiple lithium batteries. When it is necessary to repair or replace the lithium batteries, after removing the top cover, the battery holder can simply be moved out of the U-shaped bracket. Therefore, it is convenient to disassemble the lithium batteries during repair.

[0018] In this invention, the easy-to-disassemble and maintain home energy storage lithium battery module, through the battery installation mechanism, allows the lithium battery to be placed in the battery bracket, and then the U-shaped clip is inserted into the corresponding positioning slot to support and limit the lithium battery. At the same time, when it is necessary to disassemble the lithium battery, it is only necessary to remove the battery bracket from the U-shaped bracket. Therefore, the lithium battery can be easily disassembled during maintenance.

[0019] In this invention, the easy-to-disassemble and maintain home energy storage lithium battery module, through the power connection mechanism, allows the current to be transmitted through the L-shaped power transmission board, the connecting board and multiple conductive rods when charging or discharging the lithium battery, thereby enabling simultaneous discharge or charging of the lithium battery;

[0020] In this invention, the easy-to-disassemble and maintain home energy storage lithium battery module, through the charging and discharging mechanism, allows AC power to be transmitted to the rectifier via wires after the plug is inserted into the external power board. The rectifier converts the AC power into DC power, which is then transmitted to the L-shaped power board through the second resistor, so that multiple lithium batteries can be charged.

[0021] After the current from the lithium battery is transmitted to the L-shaped power supply board, the DC power can be transmitted to the inverter through the first resistor, which can then convert the DC power into AC power and transmit it to the power panel, thus facilitating the supply of electrical power to the home.

[0022] This invention enables the detachable installation of multiple lithium batteries, allowing for convenient disassembly when lithium batteries need maintenance. Furthermore, the charging and discharging mechanism in this technical solution facilitates the charging and discharging of lithium batteries, thus providing excellent convenience in practical use.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] Example 1, referring to Figure 1-9 A lithium battery module, used in the field of battery technology, includes a housing 1. A battery slot 2 is formed on the top of the housing 1 to accommodate a lithium battery 26. A mounting slot 19 is formed on one side of the housing 1 for mounting a charging / discharging mechanism. Two U-shaped brackets 5 are symmetrically fixedly mounted on the inner wall of the battery slot 2. Positioning slots 15 are formed on the top of each U-shaped bracket 5. These structures together constitute the basic framework of the lithium battery module.

[0035] Next, the battery mounting mechanism is fabricated. Each battery mounting mechanism includes a battery bracket 6, with two handles 13 symmetrically fixed to the top for easy handling and movement. Inside the battery bracket 6, a heat exchange bracket 9 is fixedly installed to support the lithium battery 26 and dissipate the heat generated when the lithium battery 26 is in operation. The lithium battery 26 is secured within the battery bracket 6 and cooled by the heat exchange bracket 9. A U-shaped retaining strip 7 is fixedly installed at the bottom of the battery bracket 6. The bottom of the U-shaped retaining strip 7 extends into the positioning groove 15 and engages with the inner wall of the positioning groove 15, thus fixing the battery mounting mechanism onto the U-shaped bracket 5 and achieving support and positioning of the lithium battery 26.

[0036] To further improve heat dissipation, two corrugated heat exchange plates 8 are symmetrically fixed inside the U-shaped bracket 5, and the heat exchange plates 8 are in contact with the corresponding heat exchange brackets 9. When the lithium battery 26 is working, the heat exchange brackets 9 transfer heat to the heat exchange plates 8. Since the heat exchange plates 8 have a corrugated structure, the contact area with the air is increased, which is conducive to the dissipation of heat, thereby continuously dissipating heat from the lithium battery 26.

[0037] To enable the charging and discharging functions of the lithium battery 26, two first contact plates 10 are symmetrically fixedly installed on the inner wall of one side of the battery holder 6. A metal transmission strip 11 is electrically connected to the side of the two first contact plates 10 that are close to each other. A contact post is electrically connected to one side of the metal transmission strip 11, with one end of the contact post extending into the battery slot 2 and fixedly connected to a contact ring 12. Two second contact plates 27 are symmetrically electrically connected to one side of the lithium battery 26. The lithium battery 26 contains a charging module and a discharging module, which are electrically connected to the two second contact plates 27 respectively. When the lithium battery 26 is placed in the battery holder 6, the first contact plates 10 and the second contact plates 27 are in electrical contact. At this time, through the transmission of current via the metal transmission strip 11, the contact post, and the contact ring 12, the lithium battery 26 can be easily charged, or current can be transmitted when the lithium battery 26 is discharging.

[0038] Next, the power connection mechanism is fabricated. The power connection mechanism includes a mounting frame 14 fixedly installed within the battery compartment 2, and a connecting plate 18 fixedly installed within the mounting frame 14. Multiple conductive rods 16 are symmetrically fixedly installed on the top of the connecting plate 18, with the top ends of each conductive rod 16 penetrating the mounting frame 14 and extending above it, and the conductive rods 16 are fixedly connected to the mounting frame 14. The conductive rods 16 pass through corresponding power connection rings 12 and are electrically connected to the power connection rings 12. An L-shaped power transmission plate 17 is electrically connected to the bottom of the connecting plate 18, with one side of the L-shaped power transmission plate 17 extending into the mounting groove 19 and connecting to the charging / discharging mechanism. When charging or discharging the lithium battery 26, current can be transmitted through the L-shaped power transmission plate 17, the connecting plate 18, and the multiple conductive rods 16, thereby enabling simultaneous charging or discharging of the lithium battery 26.

[0039] Finally, a charging and discharging mechanism is installed in the mounting slot 19. The charging and discharging mechanism is electrically connected to the power receiving mechanism and is used to charge the multiple lithium batteries 26 and output the power on the lithium batteries 26.

[0040] Next, we will design the charging and discharging mechanism in detail. A side cover plate 30 is fixedly installed at the opening of the mounting slot 19. A wire 25 is threaded through and fixedly installed on the side cover plate 30. One end of the wire 25 is connected to a plug 29 for insertion into an external power socket. The other end of the wire 25 is electrically connected to a rectifier 23, which is fixedly installed on the bottom inner wall of the mounting slot 19. The function of the rectifier 23 is to convert external alternating current into direct current for charging the lithium battery 26.

[0041] A second resistor 21 is electrically connected to the rectifier 23. The cathode of the second resistor 21 is electrically connected to the L-shaped power supply board 17, while the anode returns to be electrically connected to the rectifier 23. The main function of the second resistor 21 is to prevent the direct current output from the lithium battery 26 from flowing directly to the conductor 25, ensuring the correct direction of current flow. When the plug 29 is inserted into the external power socket, the alternating current enters the rectifier 23 through the conductor 25, is converted into direct current, and after being regulated by the second resistor 21, is finally delivered to the L-shaped power supply board 17 to charge the lithium battery 26.

[0042] In addition, the charging and discharging mechanism includes a plug-in panel 24 fixedly embedded in the side cover plate 30. The plug-in panel 24 is electrically connected to the inverter 22 on one side within the mounting slot 19. The inverter 22 converts direct current (DC) into alternating current (AC) for use by household appliances. A first resistor 20 is electrically connected to the inverter 22. The anode of the first resistor 20 is electrically connected to the L-shaped power supply plate 17, while the cathode returns to be electrically connected to the inverter 22. When the lithium battery 26 discharges, DC power enters the first resistor 20 through the L-shaped power supply plate 17, is regulated, and then transmitted to the inverter 22. After being converted to AC power, it is output through the plug-in panel 24 to power household appliances.

[0043] Example 2

[0044] refer to Figure 3 An improvement upon Example 1: A home energy storage lithium battery module that is easy to disassemble and maintain. To ensure the stability of the lithium battery 26 within the battery compartment 2, a top cover plate 3 is fitted at the opening of the battery compartment 2. Two pressure plates 4 are symmetrically fixed to the bottom of the top cover plate 3, and these two pressure plates 4 contact the corresponding two battery brackets 6. When the top cover plate 3 is fitted and connected to the battery compartment 2, the pressure plates 4 will press and limit the battery brackets 6, thereby preventing the battery brackets 6 from separating from the U-shaped brackets 5, ensuring that the lithium battery 26 is in a stable position and will not shake arbitrarily.

[0045] However, as is well known to those skilled in the art, the working principle and wiring method of lithium battery 26 are commonplace and are all conventional methods or common knowledge, so they will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0046] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
