LiU has the largest university laboratory for fluid power systems in Sweden. We aim to develop smarter and more energy efficient hydraulic systems, components and methods to reduce energy losses.

The project aims to reduce the energy consumption of vehicle load handling systems by 80 % compared to today’s solution. This is accomplished by adapting and optimizing the hydraulic system to an electric supply from a battery pack.

In a collaboration between Saab AB and Linköping University a new type of cylinder with releasable piston is under development, which allows the change of the piston area in discrete steps during operation.

The project aims to develop a new, energy efficient and quiet hydraulic piston machine for various applications.

Did you think that all it takes is changing an excavator’s diesel engine for an electric one? Well, it’s not that simple. The hydraulics can actually be adapted to the many advantages of the electric engine.

Computer control makes it possible to introduce hybrid hydraulic technology into working machines. This will not only save energy but also – in the long term – make autonomous machines possible.
