Series-hybrid propulsion system that first converts the engine output into electrical power and uses only electric traction motors for propulsion. It also uses high capacity battery package to store the regenerative energy of the vehicle and thus improves the energy efficiency. In this paper, the test driving data of series hybrid propulsion system of rubber-tired tram has been analyzed. In order to validate the performance of the series hybrid propulsion system, the energy consumptions of major components in series hybrid propulsion system have been investigated and DC-link ripple factor and the efficiency of battery pack were analyzed using test driving data of public road.
