Simulation and User Factors Analysis of Energy Consumption of Plugin Hybrid Electric Vehicles

Abstract:

The energy consumption of plugin hybrid electric vehicles (PHEVs) was simulated using forwardfacing stream of calculations, and the user influence factors of the economy of PHEVs were discussed. Then, the model of powertrain and longitudinal dynamics system of PHEVs were built based on Modelica language and utilized to simulate the fuel consumption of Chargesustaining (CS) mode and electric consumption of Chargedepleting (CD) mode under the standard driving cycle. Finally, the influencing mechanism of average driving speed and driving aggressiveness on CS fuel and CD electrical consumption was obtained by analyzing the energy consumption of each consuming component and the engine thermal efficiency.
