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.
To avoid the shunting of current, the tab needs to be carefully designed with slots and tabs to concentrate the energy and guide the weld energy to specific spots. When laser welding, the joint geometry of the battery tab weld is a lap weld, which means the laser must penetrate fully through the top tab and at least slightly into the can wall.
UWB is also suitable for creating electrical connections between cylindrical battery cells. Although proper fixation of the cell is paramount for the welding, as any significant lateral movement will reduce the vibration amplitude and consequently diminish the power of the welding process.
Parameter control also allows LBW to adapt to the thickness of the material tabs and can create thin or thick weld nuggets. In battery cell welding it is important to create thin welds due to the relatively thin battery cases and the risk of the weld penetrating the case and thus damaging the core.
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.
Battery cells are most often put into modules or packs when produced for electrically driven vehicles. The variable of greatest influence when welding battery packs is the contact resistance between the cell and the connection tab. It is crucial to minimize this variable as much as possible to prevent energy loss in the form of heat generation.

Some welding technologies have a built-in tooling mechanism because they are contact processes. Others are non-contact and require special production tooling to hold the parts in close contact when the energy is delivered. As battery packs become larger, there are additional considerations to account for. For example, the welding system must ...
Nickel strip is widely used for making battery units of two or more elements that accumulate electricity. Dot (direct-energy) welding is applied for this. It is used for welding the strip length to the poles of several elements connecting them into a battery unit. Switching circuits can be series, parallel or combined.
Welding conductive sheet interconnections to battery assemblies. Spot welding strips and tabs onto batteries in order to make battery interconnects and larger battery pack assemblies is a common production technique. Typically, battery interconnects are made from nickel strips, ideally designed with bifurcations and projections which are then ...
After inverter losses (because nothing is 100 percent efficient) you would be left with about 80 usable watt hours of energy. This is a very small battery, but it is more than enough energy to run low-power AC electronics for several hours or even all day, depending on what you are running.
