Welding techniques for battery cells and resulting electrical contact resistance…
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. In this comparison section, only the results for CuZn37 test samples according to Fig. 2 are discussed, because CuZn37 can be welded …
Resistance Welding Fundamentals
The general heat generation formula for resistance welding is: Heat = I2 x R x t x K. Where "I" is the weld current through the workpieces, "R" is the electrical resistance (in ohms) of the workpieces, "t" is the weld time (in hertz, milliseconds or microseconds), and "K" is a thermal constant. The weld current (I) and duration ...

Welding techniques for battery cells and resulting electrical contact resistance…
Hence, resistance spot welding, ultrasonic welding and laser beam welding are mostly applied. Using the example of two battery cells connected in parallel, Fig. 1 illustrates the influence of the quality of cell connections on a battery assembly. The higher electrical contact resistance RC,1 generates more heat at the terminal of cell 1.
