Battery Charging from Bi-cycle Pedal Power
Introduction
This project is started when a group of young innovators travelled for a humanitarian work in a small undeveloped village in Baray, Cambodia.The group realised that the villagers is denied of accessing clean water and electricity is expensive, thus they decided to design and create a device which can be used to charge a battery which can be used by the village.
The group made some observations and realised that the villagers are high in stamina and they are very fit as they walk to travel from places to places.Taking considerations of their observations, the group decided to make use of a bicycle to turn a dynamo to charge a 12V battery.
In this challenge, the pupils will learn about the working principles of a dynamo, battery charging/discharging procedures and electrical elements required for the project.
