6 FAQs about [Energy storage battery module welding method]
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.
Why do battery cells need to be welded?
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.
How does resistance welding affect a battery cell?
4.1.2 Effect on the battery cell Small-scale resistance welding is often the preferred method for joining Li–ion batteries into battery packs. This process ensures strong joints with an almost complete elimination of the heat impact on the joined workpieces during a short time.
Why is parameter control important in battery cell welding?
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.
Does a weld cause resistance heating of a battery?
Hence, the weld would not cause any significant resistance heating of the battery during charge or discharge . 4.3.2 Effect on the battery cell High currents must flow through the welds between battery cells in order to deliver the electricity needed to power a battery electric vehicle. These welds are the bottleneck of the electric circuit.
Are there accessibility issues with battery welding?
This means that, on the one hand, there may be accessibility issues as the testing is performed on already assembled modules or packs, and on the other hand, key performance indicators for battery welding applications, such as electrical and fatigue performance of the joints, are not served.
