Driving on electricity is the upcoming vision of mobility. voestalpine is ideally prepared for electromobility.
The future belongs to the electric drive, no matter how soon or far away that may be. It is therefore good to know that voestalpine is also one step ahead in this business field. Karl Radlmayr: “With the electrical steel strip from voestalpine Stahl GmbH, especially the innovative self-bonding coating and the compacore® lamination stacks, we have an outstanding basis for this booming market.” At the 11th voestalpine synergy platform, the head of R&D for the Metal Forming Division pointed out other voestalpine products and services for the e-mobility sector, including complete solutions for battery compartments, battery recycling and other innovations.
voestalpine and the e-sector
Examples of voestalpine products in the e-mobility sector:
- Electrical steel strip for highly efficient motors—especially the leading backlack version
- compacore® inline-bonded lamination stacks with guaranteed parameters for e-motors in the power train and actuators
- Rotor/stator stacks for e-bikes
- Rotor stacks with pressed-pin crankshaft (as future vision)
- Diverse components for e-vehicles (pressure vessel and other parts similar to the previous supplier portfolio)
- Battery compartments for e-vehicles, including lids, safety cells, and battery straps
- Bimetallic strips for low-loss transmission of electrical energy in the vehicle
- Second-use solution for e-vehicle batteries
- High-alloy steels and welding consumables for low carbon electricity production KW 50+
With the first major orders for compacore®, the lamination stacks are doing increasingly well on the market according to Radlmayr. They were soon used in e-bikes. This success is a result of the Group’s R&D activities, investments in the new annealing line and the ability to offer top-quality backlack-coated steel strip. The voestalpine company’s excellent pre-material and innovative stack manufacturing process offers customers outstanding benefits.
Once more, collaboration between voestalpine companies and divisions paid off, confirms Radlmayr: “We can offer automotive suppliers lightweight safety trays for batteries—thanks to the divisions’ multi-material expertise, e.g. in steel-aluminum combinations. With the new multi-chamber profiles, we even have steel solutions that weigh the same as fully aluminum trays but cost much less.” Bimetal products from voestalpine Precision Strip provide low-resistance energy transmission paths in the electric car. And batteries from e-vehicles could soon be on the modular racks at voestalpine Krems Finaltechnik, where they will enjoy a second working life as stationary storage units for (renewable) energy. The company’s e-expertise can also be seen in the High Performance Metals Division’s material solutions and the Metal Engineering Division’s joining expertise.
voestalpine products and solutions for e-mobility are currently being rolled out worldwide. There is an increasing global demand—not only in China, as the largest manufacturer and consumer of e-vehicles, but also in the USA and in Europe. Karl Radlmayr ventures a look into the future: “It is therefore definitely conceivable that voestalpine Automotive Components Cartersville in the USA could start manufacturing compacore® stacks.” It would also be good for the environment.
