Renault picks STMicroelectronics for supply of EV, HEV power semiconductors

The Renault Group and STMicroelectronics have announced a strategic cooperation on the design, development, manufacturing, and supply to Renault Group of STMicroelectronics’ products and related packaging solutions for the power electronics systems of battery-operated and hybrid vehicles. 

According to the joint company statement, these technologies will have significant impacts on EV driving range and charging by reducing power losses and improving efficiency, which will result in lower battery costs, more kilometres per charge, shorter charging time and reduced user-cost. 

The companies will collaborate on the development of efficient, right-sized, and modular components based on the understanding of Renault Group’s technology needs for Silicon Carbide (SiC) devices, Gallium Nitride (GaN) transistors, along with related packages and modules.

As Renault’s key innovation partner, STMicroelectronics will benefit from significant volumes guaranteed for the annual usage of these power modules and transistors from 2026-2030.  

“We are delighted to work with market leader STMicroelectronics to integrate their advanced power electronics and to co-develop technologies to further improve the energy capacity of our electric and hybrid vehicle batteries and their performance on the road and when charging. This partnership secures future supplies of key components which will significantly contribute to reducing wasted energy by 45% and decreasing the cost of the e-powertrain by 30%,  helping us fulfil our ambition of making electric vehicles affordable, profitable and popular,” said Luca de Meo, CEO, Renault Group.

Jean-Marc Chery, President and CEO, STMicroelectronics, said: “ST is at the forefront of the development of advanced power semiconductors enabling the mobility industry to move to electrified platforms. This partnership will be another step forward in the progressive decarbonisation process initiated by the mobility industry and its supply chain.”
