The transportation sector is an important sector to support the national development. As most of the energy demand in the transportation sector is used for motor vehicles in the road transportation, estimating the energy demand for motor vehicles is an important task in energy management. 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. The era of electric vehicles will not necessarily eliminate ICE vehicles. If the regulations state that ICE vehicles cannot be used anymore, many ICE vehicles will become carcasses. The solution to converting these vehicles into electric vehicles is one solution. LCGC or low-cost green car is a small vehicle with a high population in Indonesia. The large number of population and the possible high cost of electric vehicles are the background of research on converting these vehicles into electric vehicles. The vehicle used initially was an ICE vehicle with a power of 65 HP/ 6000 RPM and a torque of 86 Nm/3600 RPM. Conventional vehicle conversion (power 65 HP / 6000 RPM and torque of 86 Nm / 3600 RPM) is one solution considering the large population of conventional vehicles and the possibility of expensive electric vehicles being the background for the research on the conversion of these vehicles into electric vehicles. Charging the battery is done with a fast process with a duration of about 3 hours for a charge of 5-7 volts (65-72 volts) with a battery capacity of 150 AH times 6 pieces and the capacity of its use with a motor load of 118 A real capability obtained about 4 hours operation. The results of the calculation of the power and torque generated by the motor, the maximum power of the motor is 61.13 kW at 5000 rpm motor rotation and the resulting torque is 116.75. Selection of the transmission ratio that is very suitable for use in two-speed transmissions is the transmission ratio 1.96 for 2nd gear and 1.25 transmission ratio for 3rd gear based on calculations and from the results of analysis and calculations, the optimal value is the combination. Between 2nd and 3rd gears, the value of torque and power to speed optimization has the highest value so that the vehicle is on
