[0026] Working Principle: Lithium-ion battery packs for new energy ships are high-efficiency battery systems developed to meet the green and environmentally friendly needs of ships. They are typically used to replace traditional fuel-powered systems, reducing ship pollution. As an important component of ship power systems, lithium-ion battery packs have high energy density and long service life, and are becoming increasingly popular in new energy ships. Using lithium-ion battery packs as a power source can significantly reduce the ship's dependence on traditional fossil fuels and reduce carbon emissions. The structure of a lithium-ion battery pack includes a battery box, individual cells, and battery connectors. Individual cells are connected in series. During transportation, vibration, and use, batteries may be subjected to compression, leading to shell cracking and internal structural damage, thus affecting battery performance and safety. Lack of stable support between cells may result in large gaps, affecting effective heat dissipation. Therefore, a lithium-ion battery pack for new energy ships is designed, with the first connector 5 and the second connector 6 supporting both ends of the lithium battery 4, respectively. The lithium battery 4 has positive and negative terminals at both ends, which are used to connect the battery to the external circuit. The first connector 5 and the second connector 6 are both made of insulating material and are not conductive. The second binding sleeve 14 is connected to the first connector 5 by multiple second reinforcing rods 13, which enhances the stability of the second binding sleeve 14. The second binding sleeve 14 can support the bottom of the lithium battery 4, while the first binding sleeve 9 supports the top of the lithium battery 4. This structure enhances the stability of the lithium battery 4 installation and improves the working efficiency of the lithium battery pack. The wrapping sleeve 7 is connected to the first binding sleeve 9 by multiple first reinforcing rods 8, which enhances the compressive strength of the first binding sleeve 9. The first binding sleeve 9 and the second binding sleeve 14 are both made of insulating material, which allows the lithium battery 4 to be connected to the circuit normally. The pressure-resistant ring 10 and the gasket 11 are connected by multiple reinforcing plates 12. Triangles have stability, so by setting the reinforcing plates 12, the stability of the installation of the gasket 11 and the pressure-resistant ring 10 is enhanced.
