This report investigates the hybridization of a formula student powertrain. It starts by studying different existing solutions and technologies and continues with describing the result of this project. All decisions are driven by data and well-grounded in calculations, experiences in former Chalmers Formula Student (CFS) cars, simulations and the Formula student rules (Rules 2012). The powertrain will be a parallel hybrid with a single cylinder engine of 600 cc since its weight is much lower than the current four cylinder engine, a Yamaha Fazer. An electric machine with its sprocket on the final drive chain will be used. It will also act as a chain tensioner. The electric energy will be stored in super capacitors because of their high power per weight relation. For this application high power has higher priority than high energy content. A GT Power model of the engine has been created and delivers data for making assumptions about the predicted power of the vehicle with a single cylinder engine. Regenerative braking will be applied in order to use the braking energy for acceleration when required. All components of the powertrain will be controlled by components by National Instruments and Nira using CAN communication. The components have been packaged virtually in the CFS-10 frame, since the frame of the actual car where this powertrain is intended to be mounted is not yet built.
