Germany’s Leoni and Diehl have agreed to a strategic partnership covering battery systems for electric and hybrid vehicles.

Leoni is a global provider of energy and data management solutions in the automotive sector and other industries. Diehl is a significant partner to the automotive industry with its innovative solutions for hybrid and electric vehicles. The two companies will in future be working together on energy and data transmission as well as heat management across the entire value creation process. The partnership’s aim is to build on the skills of the two companies and to offer customers system solutions for electromobility from a single source.
Compared with the automotive business as a whole, the market for electrically powered vehicles promises disproportionately strong growth rates averaging more than 30% a year globally through to 2025. Instead of individual components, the carmakers are furthermore increasingly calling for all-in solutions and systems. Leoni and Diehl will be addressing both trends by working together.

“We are confident that we will be offering our customers new, attractive solutions in the growing market for alternative drive systems,” said Martin Stüttem, a member of Leoni AG’s Board of Directors with responsibility for the Wiring Systems Division.
In October, Leoni showcased technologies for autonomous driving at the International Suppliers Fair, where it focused on connectivity, not just for a car, but between vehicles themselves as well as to their surroundings. That requires high rates of data transmission, for which Leoni’s Dacar Ethernet cables offer bidirectional transfer of 100 Mbps and 1 Gbps (Ethernet standard).

Leoni has developed an Ethernet cable design with optimized materials to achieve high conductor symmetry even when exposed to vibration, humidity or dirt. Interference from the outside or mutual impairment of cables running next to each other can thereby be reduced.
