Explores water-based lubricants for electric vehicles

Published: 22 June 2021

To harvest the improvements and address the challenges the Swedish Energy Agency has just granted CEVT 6.2 MSEK to lead a joint project together with SKF and Luleå Technical University to explore how water-based lubricants can improve the already high efficiency of electric vehicles.

– Energy efficiency will always be a high focus area in CEVT. It must be. Our customers expect nothing less. This project enables a close collaboration with strategic industry partners as well as with the academia. The likelihood that this will be implemented in future industrialization projects is great. It will be a win not only for the partners in the project but for the environment”, says Tommy Brandt System Engineer at CEVT.

The name of the new research project is Longer Driving Range by Efficient Transmissions. The project will focus on enhanced understanding of water-based lubrication of bearings, tribological effects on gears and transmission level requirements for the use of water-based lubricants. 

– The electric vehicles of the future place new demands on materials and technologies. Through this collaboration we will expand our knowledge of water-based lubricants, giving us great insight into the future needs of sustainable vehicles,” says Gregory Zimmerman, SKF Director Product Line Electric Vehicles.

A Creaternity project

– We look forward to continue our work on water-based lubricants since it is a way to reduce the use of oils with fossil origin. It is very exciting to start optimizing the tribological system for a completely new type of lubricants. Oil lubricants have been developed over more than a hundred years. Now we must learn how surfaces and materials must be chosen to maximise performance for this lubricant as well. This project is perfectly in line with the research strategy of Luleå University of Technology. It will be a part of the research platform Creaternity which aims at finding sustainable and circular engineering solutions, says Roland Larsson, professor and scientific leader at Luleå University of Technology.
