Quick Takeaways
- The investment secures higher-capacity EV cable production inside Europe, strengthening OEM supply reliability.
- Rosenberger’s Hungarian plants become a strategic backbone for high-voltage and data connectivity in electrified vehicles.
On January 13, Rosenberger Hungary High-Voltage Cable Investment took a major step forward as the German connectivity specialist committed EUR 25.2 million to scale up manufacturing across its three Hungarian facilities in Jászárokszállás, Jászberény, and Nyírbátor. The move directly supports the growing global demand for advanced electromobility and automotive electronics solutions.
The expansion, announced by the Hungarian Investment Promotion Agency, reinforces Rosenberger’s strategic role in supplying critical connectivity technologies for the electric vehicle ecosystem. By strengthening local production, the company is positioning itself to serve OEMs and Tier-1 suppliers with faster delivery and higher capacity.
Rosenberger Hungary High-Voltage Cable Investment strengthens electromobility
The Rosenberger Hungary High-Voltage Cable Investment focuses on increasing output of high-voltage energy and data transmission systems that are essential for modern electric and hybrid vehicles. These components ensure safe, efficient, and reliable power and data flow between batteries, inverters, and vehicle control units.
Key production areas being expanded
The upgraded facilities will primarily support the manufacturing of:
These products form the backbone of next-generation vehicle architectures, where reliable connectivity directly impacts vehicle safety, charging efficiency, and overall performance.
Why Hungary is central to Rosenberger’s EV strategy
Hungary has become a major hub for electromobility manufacturing in Europe, offering strong supplier networks, skilled labor, and proximity to leading automotive OEMs. By expanding in Jászárokszállás, Jászberény, and Nyírbátor, Rosenberger gains a scalable production base aligned with rising EV and electronics demand across the region.
The investment also improves the company’s ability to support large-volume programs while maintaining the strict quality standards required for high-voltage automotive applications.
Impact on the automotive electronics supply chain
With this capacity increase, Rosenberger can respond more quickly to market growth in:
As vehicle architectures become more software-driven and electrically complex, high-voltage and data connectivity components are becoming just as critical as batteries and power electronics.
The Rosenberger Hungary High-Voltage Cable Investment therefore not only strengthens the company’s footprint in Central Europe but also enhances the resilience of the wider EV supply chain serving global automakers.
