Description

Technical Field

[0001] The utility model relates to the technical field of energy storage lithium battery integrated devices, in particular to a protective energy storage lithium battery integrated device. Background Art

[0002] In order to meet the needs of energy management and solve the challenges brought by the grid connection of renewable energy, energy storage lithium battery technology has become a widely used solution; with the rapid development of the new energy industry, energy storage systems are facing increasingly higher requirements, not only to have higher efficiency, stronger safety and reliability, but also to simplify the installation and maintenance process; therefore, the integration of energy storage lithium batteries is particularly critical; through energy storage lithium battery integrated devices, more intelligent and efficient energy management can be achieved, while improving the reliability of the system; at the same time, in order to further ensure the safety of the energy storage lithium battery integrated device and the stability of its performance, certain protection measures are usually taken for the device, thereby achieving efficient and reliable energy management; however, in the existing technology, the protective energy storage lithium battery integrated device usually only adds a layer of buffer pad between the energy storage lithium batteries, and cannot quickly dissipate heat from the lithium batteries, thereby affecting the service life of the device.

[0003] To address the aforementioned issues, Chinese patent CN218182374U discloses an integrated lithium-ion battery energy storage device, comprising an outer frame for the lithium-ion battery, mounting feet, a heat dissipation screen, a lithium-ion battery body, a heat-conducting plate, a positioning slot, a left positioning plate, and a right positioning plate. The heat dissipation screen and the heat-conducting plate cooperate to better dissipate heat from the lithium-ion battery body. However, due to limited heat dissipation space, the heat dissipation of the integrated lithium-ion battery energy storage device is relatively slow. During long periods of continuous operation, heat cannot be quickly dissipated, resulting in an internal temperature rise. This temperature accumulation not only affects the performance of the lithium-ion battery energy storage device but may also shorten its service life and even pose a safety hazard.

[0004] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

[0005] In response to the problems in the related art, the present invention proposes a protective energy storage lithium battery integrated device to overcome the above technical problems existing in the existing related art.

[0006] To this end, the specific technical solutions adopted in this utility model are as follows:

[0007] A protective energy storage lithium battery integrated device includes an energy storage box, a box cover is provided on the top of the energy storage box, a battery management module is provided on the inner wall of one end of the energy storage box, a plurality of energy storage lithium battery bodies are provided on one side of the battery of the battery management module, a partition is provided between two adjacent groups of energy storage lithium battery bodies, a buffer component is provided around the energy storage lithium battery bodies, a heat dissipation component is provided at the bottom end of the energy storage lithium battery bodies, and a plurality of battery cell strips are provided on the top of the plurality of energy storage lithium battery bodies.

[0008] Furthermore, in order to effectively protect the energy storage lithium battery body while improving the heat dissipation efficiency, the wavy structure of the buffer pad can increase the heat dissipation space around the energy storage lithium battery body, which is conducive to the diffusion of heat, and the wavy structure of the guide plate can help guide the air flow, further improving the heat dissipation effect. At the same time, under the action of the staggered arrangement of several baffles, not only the mechanical strength of the entire buffer assembly is increased, but also the air can be circulated better, thereby improving the heat dissipation efficiency, and then helping to extend the service life of the device and improve the overall performance of the system. The buffer assembly includes a buffer pad arranged on one side of the energy storage lithium battery body, and several guide plates are arranged on both sides of the buffer pad, and several baffles are arranged at the top of the guide plate; the cross-section of the buffer pad is a wavy structure, and the guide plate is arranged at the peak or trough of the buffer pad; the cross-section of the guide plate is a wavy structure; and the several baffles are staggered at the top of the guide plate.

[0009] Furthermore, in order to further improve the heat dissipation efficiency at the bottom of the energy storage lithium battery body, a more effective airflow guide can be formed as the diameter of the heat dissipation hole gradually decreases and then gradually increases as it approaches the energy storage lithium battery body, thereby increasing the heat dissipation efficiency at the bottom of the energy storage lithium battery body. The heat dissipation assembly includes a heat dissipation plate arranged at the bottom end of the energy storage lithium battery body, and a plurality of heat dissipation holes are opened on the top of the heat dissipation plate; a dividing line is provided in the middle of the heat dissipation hole, and the diameters of the two ends of the heat dissipation hole gradually increase in the direction away from the dividing line, so that the inner wall of the heat dissipation hole forms a flat end surface.

[0010] The beneficial effects of the utility model are:

[0012] 2. Through the buffer assembly, the wavy structure of the buffer pad can increase the heat dissipation space around the energy storage lithium battery body, which is conducive to the diffusion of heat. The wavy structure of the guide plate can help guide the air flow and further improve the heat dissipation effect. At the same time, the staggered arrangement of several baffles not only increases the mechanical strength of the entire buffer assembly, but also helps the air to circulate better, thereby improving the heat dissipation efficiency, thereby helping to extend the service life of the device and improving the overall performance of the system.

[0013] 3. Through the heat dissipation component, the diameter of the heat dissipation hole can gradually decrease and then gradually increase as it approaches the energy storage lithium battery body, thereby forming a more effective air flow guide and increasing the heat dissipation efficiency at the bottom of the energy storage lithium battery body.
