Have you ever wondered why today's electric vehicles can travel farther, charge faster, and are safer than ever before? Beyond breakthroughs in battery chemistry, a "silent revolution" occurring in the manufacturing process has played a pivotal role in this achievement. At the heart of this revolution is a "high precision, contactless" light — laser, which is playing an unprecedented core role. Today, let's dive into the "inner workings" of new energy vehicles and explore how laser manufacturing safeguards safety and performance.

Three Key Applications of Lasers in New Energy Vehicles

1.Power Batteries: Precision Stitching of "Battery Cells"

The power battery is the "heart" of electric vehicles, and its manufacturing process directly determines the vehicle’s range and safety. Traditional welding methods often fail to meet the extremely high consistency and reliability requirements.

Precision Welding: Laser welding acts as a highly skilled "micro-surgeon." For the battery's explosion-proof valve, lasers can achieve perfect sealing with micron-level precision, serving as a crucial line of defense for battery safety. In the tab welding process, lasers enable damage-free connections of ultra-thin materials, ensuring stable current output. During module and PACK welding, the laser’s speed and quality provide strong and reliable connections for the battery pack.

Precision Cutting: Laser cutting is used in battery cover plate processing, producing no dust or burrs, thus preventing short-circuit risks caused by metal debris residue.

2.Motor and Electric Control: The "Core" Source of Strong Power

The motor and electric control system act as the "brain and nerves" of electric vehicles.

Efficient Motors: Laser welding is applied to core components of the motor, such as the stator and rotor, ensuring structural stability and efficiency during high-speed operation, directly improving the vehicle's performance and range.

Smart Electric Control: In the precise welding of IGBT modules (core components for energy conversion and transmission), laser processes guarantee excellent heat dissipation and long-term reliability. Additionally, UV lasers are used for precision processing of the driving circuit boards (PCBs), providing a solid foundation for the electric control system.

3.Vehicle Body Lightweighting: "Car Body" Weight Reduction Strategy

"Reduce weight by one kilogram, extend range by one minute." Lightweighting the vehicle body is an important way to improve range.

Laser Welding: Laser welding replaces traditional spot welding and can achieve high-quality connections between different materials and thicknesses, reducing the vehicle's weight while increasing the overall strength and safety of the car body.

3D Cutting: Laser cutting is used for processing complex 3D structural components such as hot-formed steel door rings and battery trays, achieving high-precision, flexible production to meet the manufacturing needs of avant-garde designs in new energy vehicles.
