What is a power battery pack?

Power battery pack is one of the secondary structures of the power battery system. Power battery module consists of a number of single batteries in series and parallel, the connectors require low contact resistance, vibration resistance, and high reliability of the connection with the battery poles. The welding of the battery busbar can be said to be more important power battery welding, the use and thickness of the battery busbar varies from manufacturer to manufacturer, so manufacturers will customize the battery busbar laser welding equipment according to their own production requirements, the welding method of the battery manufacturing process and a reasonable choice of technology will directly affect the battery cost, quality, safety and consistency of the battery, Mei-Heng Machinery can be customized according to the customer's requirements laser welding equipment and provide suitable fixtures to meet the needs of automated production of battery packs.

The first section. What is the welding process of bus battery?

The welding technology of bus battery refers to the welding technology of the connection between the bus (also known as wire rod) and the battery monomer inside the battery. Inside the battery pack, the bus is responsible for connecting the electrical energy of the battery cells together to form a whole. Welding technology is the bus and battery connection of the key technology, the quality of the connection will directly affect the performance and life of the battery pack.

The traditional welding technology of the busbar battery mostly adopts resistance welding, that is, the use of heat to connect the busbar and battery monomer together. This technology has some problems, such as thermal deformation and uneven welding joints, as well as a large amount of waste and environmental pollution. In recent years, with the development of laser technology, the welding technology of passenger car batteries has gradually changed to laser welding technology to improve the quality of connection and reduce environmental pollution and energy consumption. With laser welding technology, the welded joints between busbar and battery cell are more uniform, firm and accurate, thus improving the performance and life of the battery pack.

Automated busbar laser development power battery welding machine is a machine that can be used to produce and manufacture electric new energy vehicles and other working power battery components. It combines a variety of information technologies, including enterprise automation, busbar connections, laser welding and power cell data technologies.

The machine can be used to manufacture various types of battery components, such as lithium-ion, NIMH and lead-acid batteries. With this machine, the operator simply places the battery assembly into the machine and the machine automatically performs the busbar connection and laser welding operations.

Advantages of laser welding battery.

Because the laser energy is very concentrated, the welding efficiency is high, the processing precision is high, and the depth to width ratio of the weld is large. The laser beam is easily focused, aligned and guided by optics and can be placed at a suitable distance from the workpiece and can be redirected between fixtures or obstacles around the workpiece.battery laser welding machine Due to the space constraints mentioned above, other welding rules do not work.

Small heat input, small heat-affected zone, small residual stress and deformation of the workpiece; Welding energy can be precisely controlled, welding effect is stable, welding appearance is good; Non-contact welding, fiber optic transmission, good accessibility, high degree of automation. When welding fine or thin wires, it will not be easy to produce remelting trouble like arc welding. Power batteries used in the battery is usually made of "light" aluminum, because they follow the "light" principle, so need to make "thin", the general shell, cover, bottom of the basic requirements are below 1.0 mm. General shell, cover, bottom of the basic requirements are below 1.0 mm, the current mainstream manufacturers of the basic material thickness are about 0.8 mm.

It can provide high-strength welding for various material combinations, especially suitable for welding between copper and aluminum. It is also the only technology that can weld electroplated nickel to copper.
