This thesis was made together with Syntronic, a leading design house specializing in advanced productand systems development. One of the major trends in vehicle industry today is the emergence of electricvehicles. One of the main challenges for the electric vehicles is the energy storage capacity whichtogether with powertrain, rolling- and wind resistance losses determines the vehicle range. Therefore,steps are taken in all areas from more efficient electronics to regenerative breaking which have beenwidely adopted, and the hunt for harvesting energy from other areas of the car is on its way. Energydissipated in heat from the shock absorbers can be harvested and some concepts of this have showngood results.The focus of this work was therefore to, based on previous studies, develop and evaluatea new type of shock absorber with integrated energy harvesting.A product development process was used to generate a new or develop a current concept for aregenerative shock absorber. From the product development process a compact hydraulic-electricsystem within the shock absorber were designed and evaluated on its regenerative capabilities with apeak efficiency of 32 percent while also providing an adjustable dampening coefficient. The conceptoffers a compact and affordable design by utilizing a vane pump integrated into the shock absorberpiston.
