[0002] With the transformation of the global energy structure and the large-scale development and utilization of renewable energy, energy storage technology, as a key means to address the intermittency and volatility of renewable energy, has received widespread attention and rapid development. As the core component of an energy storage system, the performance and safety of energy storage battery packs directly affect the overall operational efficiency of the system.

[0003] During the operation of energy storage battery packs, a significant amount of heat is generated during charging and discharging. If this heat cannot be dissipated effectively and promptly, the battery pack temperature will continue to rise. This not only leads to a decline in battery pack performance, such as capacity decay and reduced charging and discharging efficiency, but also shortens the battery pack's lifespan and may even trigger safety incidents such as thermal runaway, seriously threatening the safe and stable operation of the energy storage system. Therefore, an energy storage battery pack with optimized battery management system is proposed to address these issues. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The energy storage battery pack based on the battery management system optimization includes a housing and a battery pack body disposed inside the housing. The inner side of the housing is provided with a heat dissipation component for dissipating heat from the battery pack.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 3 The energy storage battery pack based on the battery management system optimization in this embodiment includes a housing 1 and a battery pack body 2 disposed inside the housing 1. The inner side of the housing 1 is provided with a heat dissipation component for dissipating heat from the battery pack.

[0023] Please see Figure 1 In this embodiment, the heat dissipation assembly includes a partition 3 fixedly connected between the top and bottom walls of the housing 1. A copper plate 4 is fixedly connected to the left side of the partition 3, and a heat dissipation fin 5 is fixedly connected to the top of the copper plate 4. A water outlet valve 6 is fixedly connected to the right side of the partition 3. A water pump 8 is fixedly connected to the right end of the water outlet valve 6. A spiral coil 9 is fixedly connected to the right end of the water pump 8. A connecting valve 10 is fixedly connected to the outlet end of the spiral coil 9.

[0024] Specifically, the top of the housing 1 is hinged with a door, and a heat dissipation vent is provided on the inner side of the door, and a dustproof net 11 is fixedly connected to the inner side of the heat dissipation vent.

[0025] It should be noted that the hinged door at the top of the housing 1 facilitates the inspection and maintenance of the equipment inside the housing 1, the heat dissipation vents help to dissipate heat from inside the housing 1, and the dustproof net 11 can effectively prevent external dust and other impurities from entering the interior of the housing 1, avoiding the adverse effects of dust on the battery pack and other components, and ensuring the normal operating environment of the energy storage battery pack.

[0026] Specifically, a mounting bracket 12 is fixedly connected to the inner top wall of the housing 1, and an infrared thermal imaging sensor 13 is fixedly connected to the mounting surface of the mounting bracket 12.

[0027] It should be noted that the infrared thermal imaging sensor 13 is fixed to the inner top wall of the housing 1 by the mounting bracket 12, and can monitor the temperature distribution of various parts of the battery pack body 2 in real time. When the local temperature of the battery pack rises abnormally, the infrared thermal imaging sensor 13 can quickly capture this information, providing data support for possible heat dissipation adjustment or fault warning, and helping to discover and deal with potential safety hazards in a timely manner.

[0028] Specifically, a base plate 14 is fixedly connected to the bottom of the housing 1, and a rubber pad 15 is fixedly connected to the bottom of the base plate 14.

[0029] It should be noted that the base plate 14 provides a stable support foundation for the housing 1, and the rubber pad 15 can play a role in buffering and shock absorption, reducing the impact of external vibration on the battery pack inside the housing 1 and protecting the battery pack from vibration damage.

[0030] Specifically, the space on the left side of the partition 3 is a water storage chamber, and the heat dissipation end of the heat dissipation fin 5 penetrates the inner top wall of the shell 1 and extends to the outside of the shell 1.

[0031] It should be noted that the water storage chamber provides a water source for the water cooling circulation in the heat dissipation component. The heat dissipation end of the heat dissipation fin 5 extends to the outside of the shell 1, which can more effectively dissipate the heat transferred from the water storage chamber through the copper plate 4 to the external environment, accelerate the heat dissipation speed, and improve the heat dissipation efficiency.

[0032] Specifically, an audible and visual alarm 16 is fixedly connected to the right side of the housing 1, a motor 17 is fixedly connected to the left side of the housing 1, an installation rod 18 is fixedly connected to the output shaft of the motor 17, the right end of the installation rod 18 passes through the left side wall of the housing 1 and extends to the water storage chamber of the housing 1, and an agitator 19 is fixedly connected to the right end of the installation rod 18.

[0033] It should be noted that the audible and visual alarm 16 can promptly issue audible and visual alarm signals when the battery pack experiences abnormal temperature or malfunctions, reminding staff to take immediate action. The motor 17 serves as the power source for the stirring blade 19, driving the stirring blade 19 to rotate in the water storage chamber via the mounting rod 18. This stirs the cooling water in the water storage chamber, making the cooling water temperature distribution more uniform and preventing localized overheating that could affect the heat dissipation effect, thereby ensuring the stable heat dissipation performance of the entire water cooling circulation system.

[0034] Specifically, motor 17 is a servo motor, and a motor frame is fixedly connected to the outside of motor 17, and the motor frame is fixedly connected to the left side of housing 1.

[0035] Specifically, the spiral coil 9 is arranged around the battery pack body 2, and the wall of the spiral coil 9 is in contact with the battery pack body 2. The connecting valve 10 is fixedly connected to the right side of the partition 3.

[0036] It should be noted that the spiral coil 9 is arranged around the battery pack body 2 and the tube wall is in contact with the battery pack body 2, which can maximize the contact area with the battery pack body 2, improve the heat exchange efficiency, and enable the heat generated by the battery pack to be transferred to the cooling water in the spiral coil 9 more quickly.

[0037] In addition, cooling plates can be added to the copper plate 4 according to budget or site requirements, and the heat dissipation fins 5 can be made in contact with the cooling plates to enhance the stability of heat dissipation.

[0038] The working principle of the above embodiments is as follows:

[0039] Water pump 8 starts and draws cooling water from the storage chamber through water pipe 7. The cooling water is pressurized after entering water pump 8 and then enters spiral coil 9. Inside spiral coil 9, the cooling water absorbs heat transferred from the battery pack and its own temperature rises. After that, the heated cooling water enters the connecting valve 10 through the outlet of spiral coil 9 and then flows back to the storage chamber from the connecting valve 10. In the storage chamber, the cooling water transfers heat to copper plate 4, and copper plate 4 then transfers heat to heat dissipation fins 5. Heat dissipation fins 5 dissipate heat to the outside of housing 1, thus completing one water cooling cycle heat dissipation process. At the same time, motor 17 starts and drives stirring blade 19 to rotate in the storage chamber through mounting rod 18 to stir the cooling water and make the cooling water temperature in the storage chamber more uniform.

[0040] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.

[0041] It should be noted that the orientations or positional relationships indicated herein are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the purpose of facilitating the description of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
