Renault Group and Vitesco Technologies join forces to develop power electronicspermissions electric and hybrid

Boulogne-Billancourt (France) and Regensburg (Germany), July 12, 2022 – Renault Group, a major player in the automotive industry, and Vitesco Technologies, a leading international manufacturer of advanced powertrain technology and electrification solutions, have announced the signing daystrategic partnership for the joint development and production of power electronics in the “One Box” package for electric and hybrid powertrains.

Under this agreement, the two partners will join forces by providing their know-how and experience for the joint development unique concept of power electronics on the market. The Renault Group will bring its expertise in electric and hybrid vehicles, while Vitesco Technologies will bring its “best-in-class” technologies and processes.

The goal is to create an important electronic unit that combines all the components in one package: a DC/DC converter.oneon-board charger OBC2 and inverter3. Renault Group and Vitesco Technologies teams will define the products and assembly processes for this “one box”, integrating the latest advanced technologies to ensure the best level of competitiveness in terms of profitability and cost.

This one-box concept will also allow gain in compactness unpublished (- 45% by volume) and mass to develop future Renault vehicles, in particular to improve habitability and passenger comfort. The configurations and assembly of various major components will be adapted to the types of electric and hybrid engines. The platform development teams will be primarily based in Toulouse.

In the development of this “One Box” it is planned to equip electric vehicles and hybrids Renault high voltage engine range from 2026, with the aim of the Renault Group to eventually assemble this production at its industrial sites in France for 100% electric vehicles. With this new partnership, the Renault Group is expanding its control of the electrical value chain by integrating this unique all-in-one power electronics system developed jointly with the company.

As part of this partnership, the Renault Group will simultaneously award Vitesco Technologies a multi-year contract to supply power electronics for Renault hybrid vehicles. In addition, Vitesco Technologies will supply the Renault Group “High Voltage Box”, which will combine a DC-DC converter and a battery electric vehicle charger from 2025.

“We are excited to take another step today with Vitesco Technologya longtime partner of the Renault Group in electric vehicles and whose know how on the Power electronics is recognized all over the world. Together we will design and develop a state-of-the-art “single box”, unique in the market, that will become a real competitive advantage. Through this strategic partnership, we are also further strengthening our control of the electricity value chain and reaffirm our desire to anchor our technological and industrial developments in electric vehicles in France.” says Gilles Le Borne, technical director of the Renault Group.

Andreas Wolf, CEO of Vitesco Technologies, explains: We are very pleased to enter into this strategic partnership with Renault Group, which is one of the largest car manufacturers and a pioneer in the field of electric vehicles. This step allows us not only to become key ally Renault Group in power electronics, but also a milestone to strengthen our growth in electrification. »

oneA DC/DC converter is a power electronics circuit that converts high voltage direct current (direct Current) from the battery to power the low-voltage network of the car with direct current 14V.
2On-Board Charger OBC (On board Charger) is a power circuit that allows recharging a high-voltage DC traction battery from the mains.
3An inverter is a power electronics circuit that drives an AC motor from the DC voltage of a traction battery. It controls engine speed, traction and energy recovery during braking.
