Environmental Performance Evaluation of Plug-in Hybrid Electric Vehicles

The reduction of CO 2 emission by the transport sector is necessary to be realized the low carbon society. In the near future, further CO 2 emission reduction is expected by the diffusion of PHEV. The aim of this study was to evaluate the potential of PHEV to reduce CO 2 emission based on real-world driving data (probe car data) and simulation. The probe car data of 35 conventional HEVs from April to August in 2011 were analyzed. The type of simulated PHEV system was all electric range, which operated only by battery power as long as available battery capacity was remaining (EV mode) , and then operated like conventional HEV after battery was depleted (HEV mode). Charging frequency was once a day at home after midnight as a realistic scenario. The results showed that the travel distance of 43% was converted to EV mode, and the gasoline consumption was reduced by 44%. The CO 2 emission was totally reduced by 17% considering electric power consumption. CO 2 emissions of each vehicle were reduced by 1-44%. CO 2 reduction amount of each vehicle varied widely reflecting their each own ways of car use and operating conditions. It is indicated that the diffusion of PHEV is a realistic and efficient measure to reduce CO 2 emissions in consideration of actual car use and operating conditions. Furthermore, low carbon power supply as well as diffusion of PHEV is more effective to CO 2 reduction.

“…First, a detailed evaluation was carried out via a numerical value simulation [9,10] to identify how the vehicle performance was adversely affected as the lithium-ion batteries installed in the vehicles deteriorated (i.e., battery capacity deterioration and internal resistance deterioration). Next, an attempt was made to determine the permissible amount of deterioration for the vehicle-mounted lithium-ion batteries based on the data that was obtained and the requirements for each type of vehicle.…”

This paper reports the results of investigating the permissible amount of battery deterioration. An investigation was carried out using the following two types of vehicles: a BEV (battery electric vehicle) and a HEV (hybrid electric vehicle). First, a detailed evaluation was carried out to identify how the vehicle performance was adversely affected as the lithium-ion batteries installed in the vehicles deteriorated. Next, an attempt was made to determine the permissible amount of deterioration for the vehicle-mounted lithium-ion batteries. In the case of the BEV, the driving distance declined by 20% when the capacity maintenance rate was approximately 80%. Therefore, this was specified as the permissible amount of battery deterioration for the BEV. In the case of the HEV, the fuel consumption increased by 20% when the maximum battery output maintenance rate was approximately 40%. Therefore, this was specified as the permissible amount of battery deterioration for the HEV.

In this paper, a simulator was built to simulate a plug-in hybrid electric vehicle (PHEV) power system. Specifically, a model adopting a series/parallel hybrid system with a planetary gear mechanism was created. With this model, the impacts of the engine on/off control and drive distance on environmental performance were analyzed using a homologation driving schedule for Japan. It was proven that when providing PHEVs to the market it will be necessary to adjust the engine on/off control to suit the actual daily drive distance of users.
