Shell and Connecting Parts

main content

The design of the casing and connecting parts of the starting lithium battery for motorcycles is one of the key factors to ensure the safe and reliable operation of the battery. The casing not only needs to protect the battery from the influence of the external environment, but also needs to have good heat dissipation and protective performance. The connecting parts need to ensure a stable connection between the battery and the motorcycle's electrical system. This article will briefly introduce the protective casing and terminal design of the starting lithium battery for motorcycles.

Protective housing

1. Material selection
Plastic casing: Plastic casing is widely used in motorcycle starting lithium batteries due to its light weight, flexible design and strong corrosion resistance. For example, the ABS plastic shell is not only lightweight but also can be molded into complex shapes to adapt to different installation Spaces. However, the heat resistance and impact resistance of plastic casings are relatively weak, so special attention should be paid to the selection of materials.
Metal casing: Metal casings (such as aluminum or stainless steel) are renowned for their high strength and durability. They can better protect the battery from physical shocks and have good heat dissipation performance, which helps to extend the battery's service life. In addition, the metal casing also has electromagnetic shielding function, which can reduce interference with other electronic devices.

2. Structural Design
Buffer design: Some motorcycle starting lithium battery casings adopt special buffer structures, such as battery mounts, to enhance impact resistance. This design can act as a buffer when the battery is subjected to external force impact, preventing the external force from directly acting on the battery cells, thereby enhancing the safety of the battery.
Sealing property: The sealing property of the casing is crucial for protecting the battery from moisture and dust. Many shell designs adopt sealing rubber rings or silicone sealing technology to ensure the stability of the internal environment of the battery.

3. Heat dissipation design
Heat dissipation is an important consideration in the design of lithium battery casings. Metal casings, due to their excellent thermal conductivity, are usually used in scenarios where efficient heat dissipation is required. In addition, some shell designs also fill the space between the battery and the shell with heat-conducting materials, such as foam, to further enhance the heat dissipation effect.

Terminal Design

1.Terminal material
Terminal materials are usually made of metals with good electrical conductivity, such as copper or copper alloys. These materials not only ensure the stable transmission of current, but also have good corrosion resistance and mechanical strength.

2. Connection method
Threaded connection: The connection between the terminal and the battery housing usually adopts a threaded connection method. This connection method is firm and reliable, and is convenient for installation and disassembly.
Welding connection: In some high-performance batteries, the connection between terminals and cells may be made by welding to ensure the stability and low resistance of the connection.

3. Terminal protection
To prevent the terminals from being corroded or damaged during use, some designs adopt a fully covered terminal structure, which can effectively protect the terminals from the influence of the external environment. In addition, the surface of the terminals is usually treated with a coating to further enhance their corrosion resistance.

Conclusion

The design of the casing and connecting parts of the lithium battery for motorcycle starting is crucial to the safety, reliability and performance of the battery. By rationally choosing the shell material, optimizing the structural design and adopting high-quality terminal design, the service life and usage safety of the battery can be effectively enhanced. With the continuous advancement of technology, the design of the casing and connecting parts of future motorcycle starting lithium batteries will pay more attention to lightweight, high performance and intelligence.
