ABSTRACT Generating an electricity by using any kind of wasted
heat as a supply. The concept that applied in this project is Seebeck effect
that directly converts heat energy to electricity to charge a device.
This proposal describes a device charger, which is powered by thermoelectric generator (TEG) power modules.
In processing the output, the application of dc-dc booster and voltage regulator is applied. The output product is a 5V,100mA at the USB socket.
OBJECTIVE To develop a thermoelectric generator device charger (5V, 100mA) To develop for consumer bring to anywhere where they can get heat source To enhance renewable energy technologies and to save the environment
PROBLEM STATEMENT How do we develop energy supply when lose power on a
smartphone during hiking & camping? What method can be charging a smartphone at anytime?
PREVIOUS WORK1. NASA spacecraft project:
• Use for many years by NASA to power spacecraft and the oil and gas industry to power remote monitoring stations around the globe.
2. Consumer applications:
• Seiko Thermic, a wristwatch powered by body heat using a thermoelectric generator
3. Previous FYP BMI student:
• Development of Portable Power Supply using Hot Water which is large scale output (240v 13A 300W) at the socket plug.
• This project is need to charge the 12V battery and convert to AC source by the inverter
METHODOLOGY Using a principle known as the Seebeck effect. Create electrical source by movement of electron in
semiconductor when the heat applied. Step up DC-DC converter to give greater output
than the input Voltage regulator to increase efficiency and give
constant output
