Focusing on Polymer Electrolyte Membrane (PEM) Fuel Cell hybrid Bus (FCB) powertrain integration, this paper presents a quasi-parallel dual-powertrain topology that can enhance powertrain reliability and extend optimization of energy distribution. This paper analyzes the redundancy of three practical topological structures for a dual-powertrain FCB, including a full-parallel structure, a quasi-serial structure, and a quasi-parallel structure. By calculation and comparison, the reliability of the quasi-parallel dualpowertrain structure and its corresponding fault redundancy is shown to be the highest. This paper also carries out an optimization design of FCB powertrain parameters by analyzing the power index and typical Chinese bus cycle. Furthermore, the innovative method of designing power sources is discussed in this paper. Not only power characteristics but also energy characteristics of batteries are fully taken into consideration in this paper. Off-board and on-board experiments verify the feasibility and redundancy of the quasi-parallel dual-powertrain. This research is of reference value for the study of FCB powertrains.
