Research On Model Development And Simulation Of Plug-in Hybrid Electric Vehicle

In this paper, Plug-in HEB is the main research object. By redesigning the powertrain system of a city bus, its powertrain was made into Plug-in driving mode. The main work included the component selection of the powertrain, parameters matching, model constructing and performance analysis.At first, established powertrain system of Plug-in HEB is single-axis parallel drive mode according to the design requirements. The component selection of the powertrain was established by performance analysis. Before the parameters matching of the powertrain system, some principles was proposed and the parameters matching procedure was designed. Then we obtained the performance parameters of the component after finishing the parameters matching,which made the necessary preparation for the following job.After then, we established the component model of the powertrain and its control system by ADVISOR.. After the total model was constructed, the dynamic performance and fuel economy of Plug-in HEB was simulated and analyzed under the typical Chinese city bus driving cycle. The simulation result indicated that: the dynamic performance and fuel economy of Plug-in HEB achieved the desired design goals. Compared to the prototype bus, the dynamic performance of Plug-in HEB decreased but still was able to meet the requirements. Fuel consumption decreased more than 30%, which exceeded the expected target.At last, the efficiency analysis of the power components shows that the parameters matching method and the control strategy are pragmatic and feasible. It can provide necessary reference for future work and the hybrid technology development.
