The system includes three main parts, namely, UC bank, motor and the converter, vehicle management unit （VMU）. Analyses results in detail on the funetional design and ex-periments on work bench of each part were also presented, which validated the reliability of the system. Furthermore, driving results in field of the bus verified the feasibility of the design of the drivetrain sys-tem.

文摘This paper proposed a design of the drivetmin system of an electric bus with ultraeapacitor （UC） as the only on-board power source. The system includes three main parts, namely, UC bank, motor and the converter, vehicle management unit （VMU）. Analyses results in detail on the funetional design and ex-periments on work bench of each part were also presented, which validated the reliability of the system. Furthermore, driving results in field of the bus verified the feasibility of the design of the drivetrain sys-tem. The bus has very good dynamic performanees and shows a promising applieations prospeet in the short and medium route buses system.
