RRoewe 550 plug-in hybrid electric vehicle (PHEV) is designed and developed by Shanghai E-Propulsion Auto Technology Co., Ltd (SEAT). Since its debut in early 2014 the supply has always been inadequate to the blooming market demand, thanks to its excellent demonstrated performance and reliability. An indepth analysis of the electric drive unit (EDU), which is the core technology of Roewe 550 PHEV, is presented in terms of vehicle energy economy and dynamic performance. The benchmark by THS of Prius III is used in the theoretical analysis and simulation. The authors hope that this article can provide the reader with some insights into Roewe 550 PHEV.
