Abstract

The advancement of transportation technology has driven innovation in environmentally friendly vehicles such as electric cars. This project aims to support vocational education through the fabrication and assembly of the rear frame of an electric vehicle, which includes the drive system, suspension, and frame structure. The stages involved include data collection, fabrication, assembly, and testing. Suspension testing results showed that the shaft length without load was 40 mm, while under a load of 60 kg, the shaft length decreased to 27 mm, and under maximum load, it further reduced to 5 mm. Testing of the electric vehicle demonstrated an average speed of 23–24 km/h. In the acceleration test, the first and second trials reached a speed of 7.78 m/s in 10 seconds, resulting in an acceleration of 0.778 m/s². In the third trial, the vehicle reached a speed of 8.06 m/s in 9 seconds, yielding an acceleration of 0.864 m/s²
