New energy car batteries refer to the advanced battery technologies used in electric vehicles (EVs) and hybrid electric vehicles (HEVs) to store and deliver electrical energy for propulsion. These batteries are designed to provide high energy density, longer range, improved performance, and increased lifespan compared to traditional lead-acid batteries or earlier generation lithium-ion batteries.

How New Energy Car Battery Welded:

The welding process for car batteries in new energy vehicles (NEVs) varies depending on the type of battery technology used. The two main types of batteries in NEVs are lithium-ion batteries and solid-state batteries.

  • Lithium-ion Batteries: Lithium-ion batteries are widely used in electric vehicles and hybrid vehicles. The cells in these batteries are typically interconnected using welding techniques.

  • Solid-State Batteries: Solid-state batteries are a promising next-generation battery technology that offers higher energy density and improved safety.

It's important to note that the welding process for car batteries requires specialized equipment and expertise to ensure the integrity and safety of the battery pack. The specific welding method used can vary between manufacturers and may be subject to ongoing advancements as battery technology evolves.

Laser welding is a widely used process in the automotive industry for joining different components, including car batteries. When it comes to car battery manufacturing or repair, laser welding offers several advantages such as precision, speed, and minimal heat input.

The procedure for laser welding on a car battery typically involves the following steps:

  1. Preparation: Before starting the welding process, the battery components that need to be joined are properly cleaned and prepared. This ensures that the welding area is free from any contaminants that could interfere with the welding process.

  2. Set-up: The battery components are positioned securely in the welding fixture or clamping system to ensure proper alignment and stability during the welding operation. This is important to achieve accurate and consistent welds.

  3. Laser beam setup: The laser welding system is configured according to the specific requirements of the battery materials and design. This includes setting the laser power, beam diameter, focal position, and other parameters based on the thickness and properties of the battery components.

  4. Welding operation: Once the laser system is set up, the welding process begins. The laser beam is precisely directed onto the joint area of the battery components to be welded. The high-intensity laser beam quickly heats the material, causing it to melt and form a weld pool.

  5. Weld formation: As the laser beam moves along the joint, the molten material solidifies, creating a strong and durable weld. The process is controlled to ensure the proper penetration and fusion of the materials.

  6. Quality control: After the welding is complete, the welded battery components may undergo various quality control inspections. These inspections can include visual examination, non-destructive testing, and measurements to verify the integrity and strength of the welds.
