Addressing Industry Challenges and Needs

As the EV industry continues to grow rapidly, manufacturers are presented with unique challenges and needs. At Laser Marking Technologies, we have designed our laser solutions for EVs around those needs and to help you resolve industry-related challenges, such as:

Traceability and compliance: EV manufacturers are subject to stringent quality control and traceability requirements. Our lasers create intricate markings that facilitate compliance with industry regulations and ensure traceability throughout the EV’s life cycle.
Battery safety and reliability: Our laser machines for EV batteries are designed to maintain the safety and reliability of the components, even after marking. Since the lasers do not compromise the material’s integrity, they ensure the functionality of EV batteries and components.
Surface preparation for bonding and welding: A well-prepared, clean surface is required to ensure strong connections between EV components. Our laser systems provide a precise and efficient EV battery laser cleaning method, preparing the surface for bonding and welding with other parts.
Marking durability and legibility: Electric vehicles are exposed to harsh conditions, making it crucial for their markings to be able to withstand the elements and remain legible. We develop laser systems that meet those demands by creating durable, long-lasting markings.

What Do Our EV Battery Laser Machines Do?

Our EV laser machines are designed for several purposes, including:

Texturizing surfaces: Lasers optimize the texturing of surfaces to gain friction areas and improve bonding strength on adhesion surfaces. Our easily controlled machines have smart vision systems to help you pinpoint exactly what areas need the texturing.
Cleaning batteries: We also have systems for EV battery laser cleaning, which is effective for cylindrical, prismatic, pouch and blade battery cells. Laser cleaning is highly precise and repeatable, with minimal risk of damage and no contact with the product. Cleaning allows the surface to weld, solder and wire bond to materials better by removing contaminants such as oil, grease and dirt.
Adding codes: Many EV manufacturers use lasers to mark code and serial numbers on the battery cover, electrodes and other components. This data is essential for traceability throughout and after the manufacturing process.
Adding aesthetics: Lasers can also add designs, slogans, logos and other aesthetics to the EV part.

Laser Color Marking

Laser color marking uses a specific focused beam to create durable, high-contrast marks on surfaces like plastics and metals used in EVs. The colors can vary depending on the material’s composition. Markings are usually identifiers, such as barcodes and serial numbers. This technique also works for branding or conveying safety information on certain parts.

Laser Annealing

Laser annealing involves controlled heating of materials without disrupting the surface. The method works by forming a layer of oxidation on the surface, which darkens as the material cools. Laser annealing is ideal for creating colorful and long-lasting markings on steel and titanium EV parts.

Laser Engraving

Laser engraving and etching are precision techniques that concentrate laser beams to remove parts of the materials from the surface to create markings. The deep engraving process leaves behind a marking you can see and feel. These methods are often used for detailed designs, serial numbers and barcodes on EV components.

Laser Welding

Laser welding usually involves a continuous wave laser used to melt and fuse two or more pieces together. This method is particularly effective for creating high-quality welds that are crucial for EV batteries and other structural components. Laser welding ensures durability while improving production efficiency.
