Abstract

In this study, the conversion is carried out by converting conventional gasoline-fueled vehicles into electric vehicles. Replacement is done by removing the driving engine and replacing it with a motor that is automatically added to the battery as an energy source. The placement of the existing components affects the center of gravity where all the weight of the car is centered at one meeting point. From the measurement and calculation results, it is found that the change in weight of conventional vehicles to electric vehicles due to the addition of motor components in front and a battery is a total of 300 kg. The added weight resulted in a significant change in relation to the change in the center of gravity that has been measured and calculated with the change in value from 38.94% (front to back) to 54.50% and being in the middle of the car because the lower, the middle, the better. Likewise, the change from 50.34% to 50.95% (from left to right) so that the lower the car's focus, the effect will be felt when the vehicle turns or maneuvers. In addition, it also aims to determine and analyze the performance of electric motors installed in convertible electric vehicles that still use manual transmissions so that the focus of research is on transmission performance and electric motors in power and torque distribution. The 3 Phase motor is installed with a battery with a clock capacity of 150 AH and a total voltage of about 72 volts DC and is supported by a 12 VDC voltage battery to support electrical accessories and braking. Vehicle analysis focuses on the power consumption which is measured and obtained using a power analyzer that has a DAQ. The vehicle is driven in real terms with 3 passengers. GPS is also used to obtain vehicle position and altitude data during testing. The derivatives of the GPS data are the vehicle's speed, acceleration, and distance. The initial hypothesis was that the vehicle could cover a distance of 30 km under normal use. The determination of power consumption patterns of electric conversion vehicles and the reliability of their work systems. From data is obtained for further study related to how to recharge the battery and improve the work system of the conversion vehicle.
