【Abstract】To reveal the development of batery and vehicle energy eficiency of electric passenger vehicle in China， ananalysisisconductedonthebateryenergydensity，vehicleenergyeficiencyandtheirinfluencingfactorsofelectric passengervehiclessince 2O14.Theresultsdemonstrate thattheaveragebatteryenergydensityreached itsadvanced level in 2019 andremained stable，butseveral performance indicators havedeclined in 2O25.Furtheranalysis indicates that increasingbateryenergyisbeneficialforimprovingthevehicleenergyeficiencyanddrivingrange，butthispositiveffect issubst enuated when the vehicle mass reaches around 2t ，indicating apoint of diminishing return forbattery energy growth.
