Electric vehicles are a manifestation of technologicaladvances in the transportation sectorthat are beingpromotedrecently. Meanwhile, in the process of converting a vehicleinto an electricvehicle, there are severalcharacteristicsthat have alsochanged, one of whichis the stability of the vehicle. This study touches a little on the effect of changes in the center of gravity and total mass of the vehicle on vehiclestability. The stabilitydiscussed in thisresearchis the roll radius and the vehicleskid. This researchwasconducted by collectingvehicle mass data and processingitinto the vehicle s center of gravity and fromthis data itwasprocessedintovehiclest ability to bediscussed. This studyanalyzes the performance of the electricmotorpowertrainelectricvehicle (EV) system as an electricvehicle motion. This studyanalyzesvariousfield conditions as variables thatwillbeused as a reference in measuring the reliabilitylevel of vehicle performance, referring to specifications, center of gravity and tire radius. The threeexisting tilt variations willbeused to determine the performance of an electricvehiclebased on the performance of the electricmotorwhichwillbeused as the basis for designing a new conversion vehicle. The methodused in thisresearchis to analyse the power, current and voltage consumed by the motorwhen operating an electricvehicle. The use of a Power Quality Analyzer (PQA) in monitoring the operation of an electricmotorwhengiven a load variation of gear speed 1 to 3 from the measurementresults, the current tends to increase at 15-20 amperes and the voltage tends to be stable, 27 volts.
