Power System of Series Hybrid Bus Match and Calculation

Taking the city bus as the researching object,the selection foundation of HEV(Hybrid Electric Vehicle) bus as well as the method concerning match calculation and related parameters optimization for the powertrain system of SHEV(Series Hybrid Electric Vehicle) was introduced.Based on the characteristics of city bus operating condition and the efficiency MAP of the driving motor,the parameters of HEV bus powertrain parts were also optimized.Some problems during this designing procedure were highlighted,thus achieving the goal of overall optimization.
