The main goals for developing hybrid power train system are reducing emissions and providing commercially viable low cost transportation solutions. To achieve these goals, a well defined set of targets and specifications are necessary for the hybrid system development. These targets and specifications are needed for design, analysis, and validation of the power train subsystems, components, and successful system integration. During hybrid system design and development, there are many alternatives and design configurations to choose from. To select the most efficient systems duty cycle data and profiles are needed to assist in defining the design targets and specifications. For buses, due to their well defined routes the duty cycles can be achieved through data acquisitions or by using the American Public Transit Association (APTA) standard duty cycle. In this paper, the APTA duty cycle profiles are used to evaluate two alternatives power train configurations for a bus series hybrid system. The first configuration consists of two electric motors and one speed transmission while the second configuration consists of one electric motor with two speed transmission. The simulation and analysis results of both configurations are presented.
