Introduction：
Energy storage battery spot welding is a welding technology used in the battery assembly process. It combines the advantages of energy storage spot welding and the specific requirements of battery welding, and has the following characteristics:
Efficient energy utilization
Energy storage release mechanism: first store electrical energy in the capacitor, and then release the stored energy to the welding part instantly during welding. This method can concentrate energy utilization, and compared with traditional continuous power supply spot welding, it reduces energy loss during welding and improves energy utilization efficiency.
Significant energy saving effect: Due to the short welding time, the overall energy consumption of energy storage battery spot welding machine is relatively low when completing the same welding task, which helps to reduce production costs and energy consumption.
High welding quality
High weld strength: The large current released instantly causes the welding part to quickly reach high temperature, forming a good metallurgical bond, thereby obtaining a high-strength weld. This is crucial to the reliability of the battery pack, ensuring that the battery is firmly connected during use and withstands various vibrations and stresses without loosening or falling off of the weld.
Small heat-affected zone: The short welding process concentrates heat on the welding part, and the surrounding area is less affected by heat. This helps to maintain the performance of battery electrodes and other components stable, reduce the risk of battery performance degradation or damage due to overheating, and is particularly suitable for heat-sensitive battery materials and structures.
Good surface quality: Due to the short welding time, the contact time between the electrode and the battery surface is also shortened accordingly, reducing the indentation and damage of the electrode on the battery surface, making the welding point surface smoother and flatter, which not only improves the appearance quality of the battery, but also avoids corrosion and other problems that may be caused by surface damage.
Strong equipment adaptability
Material compatibility: It can be used to weld a variety of battery materials, including different types of metal electrode materials (such as nickel, copper, aluminum, etc.) and battery shell materials. For material combinations of different materials and thicknesses, you only need to properly adjust the capacity, discharge voltage and other parameters of the energy storage capacitor to achieve good welding results and adapt to the production needs of a variety of battery products.
Equipment flexibility: Energy storage battery spot welding equipment is usually small in size and light in weight, which is easy to move and arrange on the production line and can adapt to different production layouts and space requirements. At the same time, the operation of the equipment is relatively simple and easy for workers to master, and the welding parameters can be quickly adjusted to meet the welding needs of batteries of different specifications.
Precise control performance
Energy precise control: By accurately controlling parameters such as the charging voltage and discharge time of the capacitor, the size of the welding energy can be accurately controlled. This makes the welding process more stable and the quality of the welds more uniform and consistent, which is conducive to ensuring the same quality of each weld in the battery pack and improving the overall performance and consistency of the battery pack.
Electrode pressure control: Equipped with a high-precision electrode pressure control system, it can accurately adjust the pressure of the electrode on the battery according to the type, size and welding process requirements of the battery. Appropriate electrode pressure is crucial to ensure the quality and stability of welds. Accurate pressure control helps avoid welding defects such as cold welds and spatter caused by excessive or insufficient pressure.
