This is a DIY Portable 12 V Battery Energy Storage Spot Welding PCB Circuit Boar. This Circuit contains an Electronic Welding Module that is the main thing in this whole product. Spot welding is welded by the principle of rapid local
Different welding processes are used depending on the design and requirements of each battery pack or module. Joints are also made to join the internal anode and cathode foils of battery cells, with ultrasonic welding (UW) being the preferred method for pouch cells.
There are many parts that need to be connected in the battery system, and welding is often the most effective and reliable connection method. Laser welding has the advantages of non-contact, high energy density, accurate heat input control, and easy automation, which is considered to be the ideal choice for electric vehicle battery manufacturing.
The findings are applicable to all kinds of battery cell casings. Additionally, the three welding techniques are compared quantitatively in terms of ultimate tensile strength, heat input into a battery cell caused by the welding process, and electrical contact resistance.
Brass (CuZn37) test samples are used for the quantitative comparison of the welding techniques, as this metal can be processed by all three welding techniques. At the end of the presented work, the suitability of resistance spot, ultrasonic and laser beam welding for connecting battery cells is evaluated.
Laser welding is an efficient and precise welding method using high energy density laser beam as heat source. Due to heat concentration, fast welding speed, small thermal effect, small welding deformation, easy to realize efficient automation and integration [15, 16, 17], it is more and more widely used in power battery manufacturing. Figure 1.
It is mainly used in banded batteries , and electric vehicle batteries are usually cylindrical or prismatic batteries, which may destroy the integrity of the battery structure under the action of pressure and vibration, so it is not suitable for the welding of electric vehicle batteries .
