Fiber lasers have many uses within the rapidly expanding e-mobility market. Many perceive e-mobility as just electric cars, but the scope is much wider than this with bikes, aircraft, buses and many more transport vehicles moving to electric power in the future. Fiber Lasers will be adopted for many reasons, but one, in particular, is the mass demand for products. Fiber lasers work quickly with the precision levels required and address the mass market demands of e-mobility.

e-mobility applications and uses

The emerging e-mobility market is creating a rapid adoption of fiber lasers, we now go on to discuss potential applications and uses.

Fiber laser welding will be heavily used in e-mobility as it has been in automotive already. There is a strong need for existing welding applications such as airbag initiators, fuel injectors and differentials. New welding applications include increased welding of the powerful electric vehicle batteries as well as hairpin welding in electric motors. The need for dissimilar metal welding will be quite commonplace as copper is the main metal used in electric vehicles due to its high levels of conductivity.

The adoption of 3D printing and additive manufacturing will be used widely in e-mobility, especially to respond to the mass demand for parts and components, devices and tools. Rapid prototyping techniques will be adopted in R&D areas and also to enable short production runs for special models, limited editions and country variants, etc.

Engraving and marking applications will be used in many ways in e-mobility. Examples include parts marking, adding a VIN (vehicle identification number), adding serial numbers and security information. These applications can be automated within manufacturing workflows. Night & Day marking is a particularly common application for Internal Combustion Engine (ICE) and electric vehicles.

Cutting is extensively used in the industry for the high-precision cutting of stator plates and battery foils and will continue to be used for cutting parts and components in electric vehicles as it has in ICE vehicles.

Drilling of all sorts of shapes and sizes will be needed, from intricate fine holes to large holes depending on what is required, one such example being the holes in metal speaker covers. Fiber lasers can be programmed to drill whatever holes are required, which will ultimately be to the benefit of many e-mobility requirements.

SPI Lasers commitment to e-mobility

SPI Lasers supply a range of Continuous Wave (CW) and Pulsed fiber lasers worldwide to many customers. We embrace e-mobility and the environmental, “clean living” values, which it brings. The closest existing market to e-mobility is automotive, where we already have a large customer base and are working hard to develop innovative solutions for the e-mobility market both now and in the future.

The main benefit of fiber lasers is their versatility, a major benefit for the e-mobility market. SPI fiber lasers can be used to mark, drill and engrave parts and components as required. Additive manufacturing will open up opportunities for the 3D printing of parts, devices and tools. Precision cutting and welding will be extensively used in the e-mobility market. Sometimes processes can lead to parts and components becoming dirty and contaminated with grease, oil, etc. In situations like this laser ablation and cleaning can be used.
