Abstract :
A comparative study was performed for two types of plug-in hybrid electric vehicles (PHEVs): GM Volt and Toyota Prius Plug-in Hybrid. First, powertrain models of the two vehicles were derived. Based on the dynamic models, a detailed component control algorithm was developed for each PHEV. Especially, a control algorithm was proposed for motor generator 1 (MG1) and MG2 to achieve optimal engine operation. In addition, an energy management strategy for selecting the operation mode was developed from the viewpoint of fuel economy, using the battery state of charge and vehicle velocity. Based on the performed simulation results, a comparative study was performed, and it was found that the role and capacity of MG1 and MG2, and the mode selection algorithm, must be determined depending on the configuration of the PHEV.
