Study on driveline parameters matching and simulation of series hybrid electric city bus

摘要

A major problem one encounters in designing the drive structure of a hybrid electric vehicle is the precise determination of the energy needed and the efficiency of the various components. Variations in the components making up the hybrid electric vehicle i.e, engine, generator, batteries, electric motor, transmission, etc. make it difficult to assess the total vehicle energy consumption. Based on theoretical analysis, a parameters selection method on engine, generator, battery, motor and the transmission radio of a Series Hybrid Electric city bus is presented in this paper and a practical example is also given Finally, through simulation results the feasibility of this method has been validated.
