Design and Development of Cost-Effective Solar Powered Electric Bicycle.

The design and development of a Solar Powered Electric Bicycle that uses solar energy along with battery power to drive the vehicle. Solar energy is a renewable, clean, and freely available energy source. By integrating a solar panel with an electric bike, the dependency on conventional charging methods can be reduced. The solar panel helps in charging the battery either partially or fully, depending on sunlight availability, thereby increasing the overall efficiency and sustainability of the vehicle. The proposed system mainly consists of a solar panel, rechargeable battery, PMDC motor, motor controller, throttle control, mechanical frame, wheels, and electrical wiring. The solar panel converts sunlight into electrical energy, which is used to charge the battery. The battery stores this energy and supplies power to the PMDC motor through the motor controller. The controller regulates the speed and torque of the motor based on the throttle input provided by the rider. A Permanent Magnet DC (PMDC) motor is used in this project due to its simple construction, high efficiency, good torque characteristics, and ease of speed control. PMDC motors are well suited for electric bike applications because they provide high starting torque and smooth operation at low speeds. The speed of the motor can be easily controlled by varying the voltage using the controller, which improves rider comfort and safety. The mechanical structure of the bike is designed to be strong, lightweight, and cost-effective.
