Under this agreement, both partners will join forces and contribute their know-how and experience to jointly develop a unique power electronics concept on the market called “One Box”. Renault will provide its expertise in electric and hybrid vehicles, while Vitesco Technologies will contribute its technologies and processes in power electronics.
The aim is to create key electronics that combine all components in one box: the DC-DC converter, the on-board charger OBC and the inverter. The latest technologies – presumably SiC and, perhaps later, GaN semiconductors – are to be used. However, the two partners did not give details.
The ‘One Box’ concept is expected to provide a significant gain in compactness (-45% in terms of volume) and mass in the development of future Renault vehicles. This is seen as an advantage, especially in terms of space and comfort of the vehicles. The configurations and assembly of the various basic components will be adapted to the different electric and hybrid powertrains. The teams of the joint development platform will mainly be based in Toulouse.
Development of the ‘One Box’ is planned for Renault’s high-voltage hybrid and electric vehicles from 2026. Renault plans to assemble the product for pure electric vehicles at its industrial sites in France. Through this new partnership and the unique “all-in-one” power electronics system co-developed in-house, Renault Group aims to extend its control of the electrified vehicle value chain.
As part of this partnership, Renault Group is simultaneously signing a multi-year contract with Vitesco for the power electronics of Renault’s hybrid vehicles. In addition, Vitesco will supply Renault Group with a so-called ‘High Voltage Box’ from 2025. This combines the DC/DC converters and charger for electric vehicles.
“We are pleased to take a new step today with Vitesco Technologies, a long-standing partner of Renault Group in the field of electric vehicles, whose expertise in power electronics is recognised worldwide. Together, we will design and develop a state-of-the-art ‘One Box’ that is unique in the market and will represent a real competitive advantage. With this strategic partnership, we are also strengthening our value chain and reaffirming once again our determination to anchor technological and industrial developments for the electric vehicle in France,” said Gilles Le Borgne, EVP Engineering of Renault Group.
The One Box represents a unique solution on the market and gives Renault a real competitive advantage, said Gilles Le Borgne, EVP Engineering of Renault Group at the signing of the contract. Andreas Wolf, CEO Vitesco Technologies, added that his company sees the cooperation as an important milestone to further strengthen the automotive supplier’s growth in the field of electrification.
