Development of software testbed using parametric design approaches for a series hybrid military vehicle

This paper deals with the component sizing of a series hybrid electric vehicle (HEV). Since the component sizes are interrelated with the power-train structures and power control algorithm, the optimal sizing cannot be determined in a simple manner. Thus, in order to simplify the sizing problem for the HEV, this paper presents parametric design approaches which identifies the sizing effects with respect to control frequency changes of each component based on a low pass filtered power control algorithm. By using the functional simulation model with Matlab/Simulink, the proposed methods can easily and rapidly calculate the power and energy capacity of each component from the heuristic rules. The component size for designing the system is determined by a weighted cost function including the mass, volume and efficiency. This paper shows the design procedure of the proposed approaches for a 6×6 series hybrid electric armored wheeled vehicle.
