6 FAQs about [Energy storage battery pack friction welding]

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.

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 is battery pack manufacturing?

Battery Pack Manufacturing and Beyond: How 3 Welding Technologies Stack Up | AltEnergyMag In battery pack manufacturing, the cells are often already assembled and the engineer is challenged with coming up with a design to join them in series and parallel to deliver optimum energy.

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.

How does a Battery TAB Weld work?

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.
