With the global emphasis on sustainable development and the rapid rise of the new energy vehicle industry, the manufacturing of battery management systems and electrical boxes has become particularly important. As one of the core components of new energy vehicles, the welding quality of the electrical box directly affects the performance and safety of the entire vehicle. Laser welding technology, with its excellent welding effect and high efficiency, has become the preferred solution in the manufacturing process of electrical boxes.

Laser welding is a welding method that utilizes a high-energy-density laser beam as a heat source to achieve material fusion by focusing the laser onto the welding area for instantaneous heating.

High speed: The welding speed of laser welding significantly exceeds that of traditional welding methods, greatly enhancing production efficiency.
High strength: The welded joint has high strength and can better withstand various pressures and vibrations during operation,
Low heat-affected zone: Reduce the thermal impact on surrounding materials and minimize deformation and stress caused by welding.
The design requirements for the electrical box of new energy vehicles not only pertain to power storage capacity, but also involve energy management and safety. The following factors determine the importance of welding technology for the electrical box:
1. Sealing: The electrical box needs to have good sealing performance to prevent water and dust from entering, ensuring the safe use of the battery
2. Lightweight: To enhance energy efficiency, electrical box designs are increasingly leaning towards lightweight, and laser welding can effectively fulfill this requirement.
3. Reliability: The electrical box is subjected to high-frequency vibrations and shocks during operation, making robust welding quality crucial.
