Renault Group, a major player in the automotive industry, and Vitesco Technologies, a leading international manufacturer in advanced powertrain technology and electrification solutions, today announced the signing of a strategic partnership agreement to jointly develop and manufacture power electronics in One Box for electric and hybrid powertrains. aggregates.
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. The Renault Group and Vitesco Technologies teams will define the products and assembly processes for this “one box”, integrating the latest cutting-edge 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This one-box concept will also allow gain in compactness unpublished (- 45% by volume) and mass to develop future Renault vehicles, in particular to increase passenger space and comfort.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 and hybrid vehicles in Renault’s main range of high-voltage engines 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 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, from 2025, Vitesco Technologies will supply the Renault Group with a “High Voltage Box” that will combine a DC-to-DC converter and a battery electric vehicle charger.
“We are excited to take another step forward today with Vitesco Technologies., a longtime partner of the Renault Group in the field of electric vehicles, whose know-how in the field of power electronics is recognized worldwide. 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 the Renault Group, one of the largest car manufacturers and a pioneer in the field of electric vehicles. This move not only establishes us as a key ally of the Renault Group in the field of power electronics, but also marks an important milestone in strengthening our growth in the field of electrification. »
one – The DC/DC converter is a power electronic circuit that converts the high voltage DC current (DC) from the battery to the vehicle’s low voltage 14V DC power grid.
2- The OBC (On Board Charger) on-board charger is a power circuit that allows you to charge a high-voltage DC traction battery from the mains.
3 – Inverter est is a power electronics circuit that drives an AC motor from the DC voltage of the traction battery. It controls engine speed, traction and energy recovery during braking.
