Batteries & EVs
Fiber laser welding is a welding process that uses a laser beam as the heat source. As non-contact tools, fiber lasers are low maintenance and offer fast welding speeds. The laser beam is highly precise and has a low heat input, which minimizes damage to the material
Laser welding needs to be controlled to detect bad welds and ensure quality. Ensuring good weld quality is getting more challenging, as laser welding is increasingly used for micro welding applications that demand more precision, like battery tab welding in the automotive industry.
We often think of the electrification of the industry as a movement away from fossil fuels to reduce global emissions. But there are other, less obvious implications that are affecting electric motor manufacturers and consumers.
The advantages brought by hairpin motors are making electric vehicles more competitive not only with previous generations of EVs, but also with combustion engines. They are more efficient, have a higher power density and thermal performance, and are simpler to manufacture.
Laser spot welding is a welding process that uses the power of a laser beam to join two metal surfaces at a single spot. Laser seam welding is when surfaces are welded over a long, continuous surface.
Electric vehicle battery packs have complex requirements since they need to withstand large temperature ranges and vibrations. In this article, we will explore the complexities of EV battery manufacturing technologies.
EV batteries are composed of cells, and there are many types of cells. In this article, we will break them down in categories and go over the most important types. We will also discuss possible future cell types and how they can change the automotive industry.
There are three main types of lithium-ion batteries: cylindrical cells, prismatic cells, and pouch cells. In the EV industry, the most promising developments revolve around cylindrical and prismatic cells.
