Figure7.Eightcandidateswithoperatingmodes. 3.ComponentLossModel AsshowninFigure7,eightcandidates fornewPHEVconfigurationswereobtainedusingthe additional clutchandbrake. Ingeneral, it is expected that, as thenumberof theoperatingmodes increases, thefueleconomyincreases, since thePHEVcanbeoperatedwithhighefficiencybyselecting theproperoperatingmode for thegivenwheel torqueandspeed. However, additionaldrivetrain componentssuchas theclutchandbrakecauseparasiticpower loss. Therefore, theprosandconsof themulti-modeoperationneedtobeevaluatedwhenaddingtheoperatingmode. In this study, toevaluate theeffectof thepowerelectronic (PE) lossanddrivetrain lossonthe fuel economy, thecomponent lossmodelswereobtainedbasedonthemathematicalgoverningequation andexperimental results. 271
