研究目的
To design and fabricate a solar powered wheelchair for handicapped people that is affordable, self-driven, and useful for both indoor and outdoor activities.
研究成果
The solar powered wheelchair is an environmentally friendly solution that provides mobility for physically challenged individuals. It offers a journey of 2-3 hours on a single charge and is designed to be affordable for the common man.
研究不足
The solar panels' efficiency is dependent on sunlight availability, and the wheelchair's operation is limited to 2-3 hours on a single charge.
1：Experimental Design and Method Selection:
The design includes solar panels, a battery, a charge controller, and a brushless DC motor. The methodology focuses on converting solar energy into electrical energy to power the wheelchair.
2：Sample Selection and Data Sources:
The wheelchair is designed for a maximum load capacity of 150 kg, including the person.
3：List of Experimental Equipment and Materials:
Solar panels (60W, 21.4V, 2 No’s), charge controller (24V, 10A), brushless DC motor (24V, 160W, 1500 rpm), and batteries (12V, 20AH, 2 Nos.).
4：4V, 2 No’s), charge controller (24V, 10A), brushless DC motor (24V, 160W, 1500 rpm), and batteries (12V, 20AH, 2 Nos.).
Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: Solar panels convert sunlight into electricity, which is stored in batteries via a charge controller. The battery then powers the brushless DC motor to drive the wheelchair.
5：Data Analysis Methods:
MATLAB simulation was used to analyze battery charging from solar panels with and without MPPT, and from AC supply.
