Revolutionary Project Aims to Redefine Electric Vehicle Performance, Cost-Effectiveness, and Compatibility
Vienna, Austria – March 27, 2025 – A groundbreaking European Union-funded project, ‘nExt geNeration 1200V eLectric hIGH volTage powErtraiN’ (ENLIGHTEN), is poised to reshape the landscape of electric vehicle (EV) technology. The ambitious initiative, running until 2028, is focused on developing, integrating, and rigorously testing a next-generation electric powertrain operating at a nominal voltage of 1200 volts – a significant leap beyond current industry standards. This project promises to deliver enhanced performance, optimized costs, and a more sustainable system architecture for the future of electric mobility.
Addressing the Growing Demand for Efficient Electric Vehicles
The automotive industry is undergoing a rapid and crucial transition to electrification. As EV adoption accelerates, the need for improved powertrain efficiency and performance becomes increasingly critical. The ENLIGHTEN project directly addresses this challenge by pushing the boundaries of voltage technology. Current electric vehicles predominantly utilize 800-volt systems, but the ENLIGHTEN project’s 1200-volt architecture offers the potential for substantial gains in efficiency and power delivery.
Key Innovations Driving the ENLIGHTEN Project
The ENLIGHTEN project isn’t just about increasing voltage; it’s about a holistic approach to powertrain innovation. Several key technological advancements are central to the project’s goals:
- Dual-Voltage Battery System: The project incorporates a dynamic dual-voltage battery system, allowing for flexible operation and optimized performance under varying driving conditions. This adaptability is crucial for maximizing range and efficiency.
- Gallium Nitride (GaN) Technology: Fast and efficient DC/DC converters based on Gallium Nitride (GaN) semiconductors are being developed. GaN technology allows for smaller, more efficient power electronics, reducing energy losses and improving overall system performance.
- Integrated Motor-Inverter Powertrain: The project aims to create an integrated motor-inverter powertrain, maximizing power density and efficiency. This integrated design minimizes losses and simplifies the overall system architecture.
- Multilevel GaN Converter Topology: An innovative E-drive inverter utilizing a highly efficient multilevel GaN converter topology is being developed. This advanced inverter design minimizes harmonic distortion and improves power quality.
- AC/DC On-Board Charger: An AC/DC capable on-board charger will ensure seamless compatibility with existing charging infrastructure, a critical factor for widespread adoption.
Backward Compatibility and Industry Collaboration
A key consideration for the ENLIGHTEN project is backward compatibility. Researchers are committed to ensuring that the new 1200-volt powertrain can function effectively with existing charging infrastructures operating at 500 or 1000 volts. This commitment minimizes disruption and facilitates a smoother transition to higher-voltage systems.
The project boasts a powerful consortium of industry and academic partners, demonstrating a shared commitment to advancing electric vehicle technology. Leading the project is the Austrian Institute of Technology, with significant contributions from Manifattura Automobili Torino, Lead Tech, Cambridge GaN Devices, and Eaton. The consortium also includes renowned research institutions such as IFP Energies Nouvelles, Aarhus University, Ingolstadt University, and Politecnico di Torino, alongside associate partners FPT Motorenforschung and ETH Zurich.
“As the automotive industry accelerates its pivotal shift to electrification, it’s essential to enhance powertrain efficiency,” stated Shane Malo, specialist engineer at Eaton Research Labs. “Our work on a 1200 volt powertrain will reduce energy losses and ensure higher power delivery for demanding applications. We’re also considering the wider impact on manufacturers, suppliers, and charging infrastructure to create a solution that’s both cost-effective and commercially viable. Ultimately, our efforts will enable more sustainable electric vehicles with longer range, faster charging times, and greater reliability.”
Joergen von Bodenhausen, senior manager of government programs at Eaton, added, “Collaborating with so many leading partners offers fantastic learning opportunities for our team and acts as a force multiplier on our own R&D investments. As the transition to electric vehicles accelerates, this project will also position Eaton at the forefront of powertrain innovation and ensure we’re ready to meet future demands in the automotive industry.”
Project Timeline and Milestones
The ENLIGHTEN project is structured around a clear timeline with defined milestones:
- February 2025 (Launch): Official project launch and initiation of research activities.
- End of 2025: Confirmation of powertrain topology and finalization of electrical and mechanical requirements.
