An increased environmental awareness and higher climate goals increases the demands of future developed technology. Focus is thereby directed towards energy efficiency where transport vehicles are affected in great extent. This results in an increment in green vehicles and technical solutions to decrease the impact on the environment, where the engines energy efficiency is not the only system to be considered. One example of a developed technical solution to decrease the environmental impact is a regenerating system that regenerates the braking energy. Research about energy regenerating technical solutions, is thereby considered to be crucial in respect to a high energy goal with green vehicles.With energy regenerating technical solutions in mind, an increased interest is observed where the potential of the schlock absorber is investigated. Several research projects have been performed with varied result depending on the technical solution to regenerate energy. Unlike regenerating brakes, regenerating shock absorbers has not yet been commercialized. The main reason to this is believed to involve a difference in the shock absorbers behaviour which influence the comfort and handling. Other reasons might involve a reduced life span and a low regenerative efficiency. To calculate the power that originates from the work done by the shock absorber, measurements with moving car in different conditions were performed. The measurements was performed at the front axle on the left side and generated the most mean power of 150 W. This power was generated while moving in the city centre where there were several road bumps which were beneficial to the power generation. The power generation indicates that it would be benefited if the power could be regenerated and used in other electrical systems in the vehicle.
