SingleOilCnL aims to support the industry in realizing two main goals:

1. To develop and validate 20% more powerful electric powertrains with the same energy efficiency, robustness and cost (4 pareto criteria) compared to the most modern water-glycol (WG) cooling (PE) and passive direct oil cooling and lubrication (engine and gearbox) systems by eliminating the water-glycol (WG) cooling circuit and using the existing oil circuit for combined single oil-based lubrication and cooling.
2. Develop and validate design rules using an existing design tool which will be used to optimize a single oil-based cooling and lubrication system, considering the above 4 pareto criteria.

Different challenges need to be addressed by different innovations within SingleOilCnL to achieve these important goals so that the industry can use these fully interconnected single oil-based systems. This includes advanced direct jet and jacket-cooled engines, oil-based cooled power electronics (PE), and oil-cooled and lubricated gears, bearings and clutches.

The design tool allows for simultaneous optimization of the physical and control parameters of single oil-based systems and evaluates the resulting performance and costs against the corresponding passively mixed (oil-WG) cooled and lubricated benchmark. In addition, oil degradation analysis will be performed and modeled so that the degradation process of the active single oil-based systems can be evaluated. This project will build on the results and knowledge gained in previous Flanders MAKE projects such as Hipercool, Intlub, EMVeMFP7, EMtechno, Drivetrain Co-Design and Profensto, and expand these
