Solar Based Hybrid Electric Powered Wheel Chair

Abstract

Differently abled people face many hardships in life, having to be dependent on a third person to move from place to place. To provide them with a supporting aid, many scientists have been toiling for a long time. The invention of wheel chair is a great boon to them but it still restricts their motion. This project aims at providing them with a non-polluting and cost effective solution in the form of a - Hybrid Solar Powered Electric Wheel Chair. The project implements two state battery charging using Single Ended Primary Inductor Converter (SEPIC) and Maximum Power Point Tracking (MPPT) algorithm for efficient battery charging and improved battery life. The key achievements are: successful implementation of Estimate Perturb and Perturb (EPP) algorithm for MPPT and the construction of a durable and car-sized wheel-chair capable of zero radius turns.
