There are certain differences in the layout of the energy systems of plug-in hybrid vehicles (PHEVs), which will result in the effects of energy management strategies. Based on the analysis of the technical characteristics of the single-motor mainstream technology routes P2, P3 and P4, this paper establishes a parallel PHEV model with different configurations based on the rule control strategy, and analyzes the impact of different configurations on the fuel economy of automobiles under the China Automotive Test Cycle (CATC).The results show that in the CD and CS stages, the P3 configuration has lower fuel consumption, and its pure electric driving range is relatively high. The P3 configuration pure electric cruising range is 0.2km and 3.1km higher than P2 and P4 respectively. This result is instructive for researchers to study the development of hybrid vehicles.
