[0026] The following diagrams provide a more detailed description of the outdoor energy storage battery pack structure of the present invention, illustrating preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0027] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0028] like Figures 1 to 4 As shown, an embodiment of the present utility model proposes an outdoor energy storage battery pack structure, including a battery module 2, a plug-in terminal 6 and a shell 1.

[0029] Specifically, the battery module 2 is disposed inside the housing 1 , and the battery module 2 is used to store electrical energy and discharge it through the plug-in terminal 6 .

[0030] The plug-in terminal 6 is fixedly disposed on the side wall of the housing 1 , and the plug-in terminal 6 is electrically connected to the battery module 2 .

[0031] The shell 1 includes a front panel 101 and a rear box body 102, and the front panel 101 is detachably connected to the rear box body 102. A reinforcing plate 1012 is provided on the front panel 101, and the reinforcing plate 1012 is in close contact with the rear box body 102. A sealing strip 1011 is also provided on the front panel 101, which is in close contact with the rear box body 102.

[0032] In this embodiment, a fixing block 1021 is provided on the outer edge of the opening side of the rear case 102. A tapered screw 1022 is threadedly connected to the fixing block 1021. The tapered screw 1022 passes through the front panel 101 and is connected to the fixing block 1021. After the front panel 101 and the rear case 102 are connected, the tapered screw 1022 passes through the front panel 101 and is threadedly installed on the fixing block 1021 on the rear case 102, completing the quick connection installation between the front panel 101 and the rear case 102.

[0033] Among them, the front panel 101 and the rear box body 102 are mechanically connected through the cooperation between the fixing block 1021 and the conical screw 1022. At the same time, the connection between the fixing block 1021 and the conical screw 1022 realizes the electrical connection between the front panel 101 and the rear box body 102, which facilitates the subsequent grounding operation of the entire shell 1.

[0034] In one embodiment, a gap is reserved at the connection between the fixing block 1021 and the rear box 102 for draining rainwater. When it rains, rainwater falls onto the top surface of the rear box 102 and flows out through the gap, preventing rainwater from accumulating on the rear box for a long time and causing corrosion of the rear box.

[0035] In order to facilitate the transportation and movement of the entire battery pack, a waterproof handle 8 is provided on the side wall of the rear box.

[0036] Furthermore, a fire-fighting device 1013 is installed inside the front panel 101 , a ventilation valve 4 is installed on the side of the rear box body 102 , and the lead wire of the fire-fighting device 1013 is close to the ventilation valve 4 .

[0037] Specifically, the fire-fighting device 1013 is applicable to multiple application scenarios of lithium battery PACK, such as battery module 2, management system, box and exhaust system, etc., which can effectively reduce the risk of fire and improve the safety performance and reliability of new energy vehicles.

[0038] For example, the perfluorohexanone automatic fire extinguishing device is a new type of automatic fire extinguishing device that uses perfluorohexanone as the extinguishing agent. Perfluorohexanone is a clear liquid with advantages such as high fire extinguishing efficiency, environmental friendliness, and low toxicity. At room temperature and pressure, perfluorohexanone can exist in either gaseous or liquid form and has excellent chemical stability. When exposed to high temperatures, perfluorohexanone rapidly vaporizes, releasing a large amount of heat and rapidly extinguishing the flame.

[0039] Furthermore, a reinforcing rib 1024 is welded inside the rear box 102 , and the battery module 2 is fixed to the reinforcing rib 1024 by flange screws 1025 . A cell data acquisition board connected to the battery module 2 is provided on the battery module 2 .

[0040] In a specific embodiment, a BMS module 3 is provided inside the rear box 102 , and the BMS module 3 is electrically connected to the battery cell data acquisition board.

[0041] In this embodiment, the reinforcing ribs 1024 are fixedly arranged on the inner wall of the rear box body 102, and the battery cell data acquisition board is fixedly mounted on the reinforcing ribs 1024. The reinforcing ribs 1024 can enhance the installation strength of the electronic components, thereby extending the service life of the entire battery pack structure.

[0042] During the use of the battery pack structure, the cell data acquisition board is a key component of the electric vehicle's battery management system (BMS). It is responsible for connecting, collecting, and transmitting battery cell voltage and temperature data, and also provides cell protection functions such as overcurrent protection and automatic disconnection in the event of abnormal short circuits. The BMS module 3 is a crucial system in electric vehicles (EVs), its main function being to monitor and manage the battery's status and performance to ensure safe and long-term battery use. The BMS achieves its functions through the following aspects:

[0043] (1) Monitoring battery status: BMS monitors the status of all batteries in units of battery cells, including voltage measurement, current measurement and temperature measurement.

[0044] (2) Ensure uniform battery performance: BMS uses control functions to make the performance differences of each battery cell tend to be uniform, avoiding the aging of individual battery cells affecting the performance and life of the entire battery pack.

[0045] (3) Improve safety: By monitoring the battery temperature and voltage, ensure that the battery is used within the appropriate temperature range to prevent overcharging or over-discharging, thereby ensuring safety.

[0046] (4) Extending battery life: Through the balancing function, BMS is able to extend the service life of the battery, which is crucial for the long-term operation of electric vehicles.

[0047] (5) Support high power and high heat resistance: With the development of electric vehicle technology, BMS needs to support high power and high heat resistance to adapt to the increase of battery voltage and use in high temperature environment.

[0048] (6) High-precision control: BMS needs to have high-precision temperature and voltage control capabilities to ensure the performance and safety of the battery system.

[0049] Furthermore, a communication port 5 and a button switch 7 are provided on the side of the rear box 102 , and the communication port 5 , the button switch 7 and the plug-in terminal 6 are all connected to the BMS module 3 .

[0050] Specifically, the plug-in terminals 6 are divided into two positive poles and two negative poles. The positive pole of the battery module 2 is connected to the two positive plug-in terminals 6 via a positive connection bar 11. A cable is provided on the positive connection bar 11 to connect to the power supply line of the BMS module 3. An insulating baffle 12 is provided in front of the positive connection bar 11. The B- and P- terminals of the BMS module 3 are respectively connected to the negative pole of the battery module 2 and the two negative plug-in terminals 6 via the B- connection bar 10 and the P- connection bar 9.

[0051] In one embodiment, the bottom of the rear box is provided with a grounding point 1023. Two grounding points 1023 are provided on the rear box 102, which can be used as a series connection of the grounding points 1023 and can also ensure the consistency of the front and back and left and right of the battery pack when stacked up and down.

[0052] Compared with the prior art, the present invention has at least the following beneficial effects:

[0053] The utility model can greatly enhance the strength and sealing of the battery pack structure by arranging a reinforcing plate and a sealing strip between the front panel and the rear box of the battery pack structure, and can reduce the maintenance frequency of the battery pack structure. In addition, a fire-fighting device is arranged inside, which can greatly reduce the fire safety risk.

[0054] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
