Simulation research of energy management strategy for range extended electric bus

Based on the analysis of configuration of Range Extended Electric Bus (REEB), the article studies two energy management strategy, which are Charge-Depleting Charge-Sustaining (CDCS) and blended type. On the foundation of creating a vehicle simulation model, the article takes a simulation analysis on the economy of Range Extended Electric Bus. Take the Chinese city bus driving cycle conditions of daily travel mileage 200km for example, the simulation results show that comparing with blended control strategy, Auxiliary Power Unit (APU) application load following control methods with CDCS management strategy have certain improvement on the electric consumption and fuel consumption.
