Designing a hybrid drive train implies, that choices have to be made regarding the drive train structure, component technologies and sizes. Designing an appropriate Energy Management Strategy (EMS), that facilitates the usage of the chosen components and drive train structure to its best performance is complementary to the overall design problem. Due to the complexity of hybrid vehicle drive trains, the design of topologies, component technologies and the control strategy forms a considerable challenge for engineers.This paper presents a modeling and design approach in characterizing the component technologies, determining the optimal degree-of-hybridization for the drive train and energy storage system (dual-storage), and designing the control strategy of a hybrid drivetrain for a mid-sized passenger car. Thereby, an innovative dual-energy storage system consisting of a flywheel (low energy/high power) and a battery (high energy/low power) is discussed. The flywheel is used for quick engine start and power-assisting during acceleration (medium-/high speed areas) of the vehicle, whereas the battery is used for electric driving (low speed areas) and storing of recuperated brake energy. The concept is compared with two other hybrid topology concepts, i.e., a series-parallel - and a parallel hybrid topology, whereby power-assisting and low speed driving is performed fully electrically.
