6 FAQs about [Does the energy storage battery welding technology require high]

Why do EV batteries need to be welded?

Welding technology used for EV battery assembly must minimize the cell-to-tab electric resistance for top battery performance and safety . Thermal runaway is always a hazard given the hyper energy density of EV batteries . Improper connection escalates this risk by increasing the cell-to-tab resistance .

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.

Which weld is best for EV battery packs?

Use minimal weld energy to prevent excessive heating of the internal cell separator . High quality welds are of uniform width and have no gaps. Thin welds are more suited for EV battery packs. Thicker ones can penetrate the casings. Proper welds address the following welding challenges & :

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.

How long does it take to weld a battery pack?

For a battery pack consisting of 117 Cells (9 x 13), this means there are 234 sites to weld and total process time of 514.8 seconds. Since laser welding is a non-contact process, the only motion is making a weld pattern and the motion moving the beam from cell to cell. The weld cycle time is a combination of shots and small motion on a cell.

Can a laser be used for battery module welding?

Laser welding is significantly faster showing the allure of the laser for battery module welding. Cycle time can be reduced even further with the use of a galvo scanning system, where some motion is handled by quick motions in the galvo head, and then indexed after all cells within the welding field are addressed.
