What is ENLIGHTEN?
ENLIGHTEN is a European research project that aims to develop and test a next-generation 1200V electric powertrain for battery electric vehicles. By increasing the voltage beyond today’s 800V standard, the project seeks to reduce energy losses, improve charging speed, lower costs, and optimize material use.
The project will design a complete high-voltage drivetrain, including a dual-voltage battery, GaN-based inverter and motor, AC/DC combo-charger, and smart control systems, all integrated and tested in a demonstration vehicle. Through a combination of virtual simulation and real-world testing, ENLIGHTEN will define the optimal voltage level for future electric vehicles and deliver key technologies ready for industrial adoption.
Key Technologies
Our Vision
ENLIGHTEN focuses on three core technological areas to build a next-generation 1200V electric powertrain that improves efficiency, charging speed, and system integration.
– AREA I –
Power Electronics & E-Drive
Development of an integrated E-drive combining a multi-level GaN-based inverter and electric motor.
Key benefits include:
- Up to 30% loss reduction at partial load
- 99% peak efficiency
- AI-driven predictive control for enhanced reliability
- 20% cost reduction through compact, efficient design
– AREA II –
Battery Technology
Design of a dual-voltage battery system (1200V / <1000V) for efficient driving and fast charging.
Highlights:
- 10-minute ultra-fast charging (20–80% SOC)
- Advanced cooling with phase-change materials
- Backwards compatibility with 1000V infrastructure
– AREA III –
System Integration & Architecture
Ensures seamless interaction across all components (battery, charger, E-drive).
Key developments:
- Smart power distribution unit (PDU)
- Intermediate DC/DC converter
- Dynamic voltage switching for optimal performance in real time
For a Cleaner, and Brighter Future
Our Vision
To support Europe’s transition toward zero-emission mobility by developing smarter, faster, and more efficient electric powertrain technologies.
Aligned with the European Green Deal and the Fit-for-55 targets, ENLIGHTEN contributes to the decarbonisation of road transport, a sector responsible for nearly a quarter of the EU’s greenhouse gas emissions, by enabling cleaner, more accessible electric vehicles for all.
An experienced European consortium
ENLIGHTEN brings together 11 partners from 8 countries, combining leading expertise from industry, research, and academia. The consortium includes technology providers, automotive innovators, and research institutions working together to develop and validate a new high-voltage electric powertrain.
This multidisciplinary team ensures that all aspects of the system, from design and simulation to integration and testing, are approached with both scientific rigour and real-world applicability.
