Descriptions:

It is a green project using an incentive grant project to design an electric bicycle for testing and running. It consists of 48V BLDC motor, 12V batteries (4 in series), the motor contoller and the PIC microcontroller. The input for BLDC is 48 Vdc battery. The motor controller converts this voltage to a powerful 3-phase AC power (about 500W) for driving BLDC using an inverter circuit. The BLDC motor has 3 hall sensors built inside it to sense the motor position.  

A hand throttle and hand brake is used to control the speed. The maximum speed is 35km/h. With 12V,7Ah batteries, you may drive the bicycle for half an hour before need to be charged again. The charging process is based on 48V-based voltage using solar panel (solar charging station at 52V, 3 units of panels) or may be plugged through home socket output (240Vac). The motor has special features built using PIC microcontroller i.e speedometer and odometer. It is also equipped with a smart protection system using a gyrometer to avoid the system from being stolen.

Prinsip operasi

Sebuah projek membangunkan sebuah basikal elektrik. Sistem menggunakan voltan 48V, motor jenis BLDC(brushless DC motor) yg mana inputnya bekalan DC (bateri 48V) ditukar kpd AC 3 fasa utk menghasillkan power yg cukup besar (sekitar 500W bg menggerakkan penunggang). Sistem dilengkapi dengan sebuah meter indikator digital yg dibina berasaskan PIC utk memaparkan status kenderaan (STOP, Gear 1,2,3,4), speedometer (km/h) dan mileage (m). Sistem juga dibina alat pencegah kecurian berasaskan accelerometer dan alat ini dikawal oleh remote control.

Throttle tangan digunakan utk memecut kenderaan. Kelajuan maksimum direkodkan 35km/h. Ketepatan halaju dan mileage telah disahkan dgn penggunaan GoogleEarth bg merekod track perjalanan. Sistem bekalan bateri 48V dicas menggunakan tenaga solar (charging station). Juga boleh menggunakan plug dr rumah (240V) dan memerlukan penukar voltan turun.
