The project involved retro-converting a conventional petrol-powered Honda Aviator into an electric scooter by integrating the key components required for the conversion. These included a hub motor, motor controller, DC-DC converter, rechargeable battery pack, throttle, digital display, and main power switch.
The scooter used a 48 V, 23 Ah hub motor as the primary source of propulsion. The motor was waterproof, making it suitable for operation in different conditions. A motor controller regulated the power delivered to the motor based on the throttle input and controlled the scooter's overall operation.
For energy storage, we used a 48 V, 25 Ah lithium-phosphate battery pack. A step-down converter reduced the battery voltage from 48 V to 12 V to supply components such as the lighting system and digital speedometer. The digital display provided information including distance travelled and battery state of charge.
Safety was also considered in the electrical design. The scooter included a main power switch and a miniature circuit breaker (MCB) to disconnect the power supply and protect the electrical system in the event of a short circuit.
The project brought together the mechanical and electrical integration required to convert the existing petrol-powered scooter into a functional electric vehicle.
