High-voltage electrification Distribute power safely

The electrification of vehicles presents many manufacturers with new challenges. High demands are placed on reliability and ease of use, particularly when connecting, distributing, switching, and securing high-voltage applications. Due to the current strengths, these devices are subject to high thermal loads, but must also be weather- and aging-resistant. Wölfle has been working on the topic of e-mobility for years and is working with many OEMs as a research and systems partner on the vehicles of tomorrow.
