Energy storage battery welding working principle diagram

Which welding techniques can be used for connecting battery cells?

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.

Can a battery cell casing be welded?

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.

What are the different types of battery welding methods?

smaller power tool equipment, home installations (PowerWall) and electric cars.Batteries are combined into sets usually using spot and projection resistan e welding, ultrasonic and laser welding, less often by mechanical methods [1,8]. The quality of connections of each battery with the busbar

How a cell connection affects the performance of a battery system?

Every single cell connection influences the functionality and efficiency of the whole battery system. Resistance spot, ultrasonic or laser beam welding are mostly used for connecting battery cells in the production of large battery assemblies.

What is the maximum current of a battery Weld?

ximated from the battery welding station of one of the manufacturing companies. The maximum value of current was 2.2 kA.For a change in the current value in the range of +/- 10% from the maximum value, i.e. 2.0/2.4 kA, the weld diameter is reduced by 55% and increased by 60%, respectively,

How can a laser beam be used to connect a battery cell?

To position the laser beam onto the work piece, the scanner optics Remote Welding Elephant by Arges was used. This optics This Section quantitatively compares the three presented welding techniques for connecting battery cells in terms of electrical contact resistance, ultimate tensile force and heat input into the cell.
