A research on the energy consumption characteristics of plug-in HEV

In this paper, the characteristics of energy consumption and its influencing factors of plug-in hybrid electric vehicles are studied through regulation test and road test. The regulation test is done as per European regulation ECE R101 and in road tests, several PHEVs are organized to run in daily driving mode by owners in Tianjin with fuel and electricity consumptions as well as driving conditions data obtained. The results show that the energy consumption of PHEV is closely related to its rated range and the energy consumption curve of PHEV in real operation close to normal temperature state can be obtained by expanding regulation tests. The change in ambient temperature and the use of air conditioner have great effects on the energy consumption of PHEV and thus for better reflecting real energy consumption, it is essential to add air conditioner test in related regulation.
