Thermoelectric Generator (TEG) Waste Heat Harvester

Approx. component budget: Rs. 5,000 - 9,000

Objective

Measure the power generated by TEG modules at different temperature differences and see how well it can charge a battery.

What you will build

TEG modules clamped between a hot plate (heater, stove or exhaust pipe) and a heat sink, with a boost converter to charge a small battery, and temperature and power measurement.

Results you can expect

• Open-circuit voltage and power vs temperature difference
• Maximum power point
• Effect of heat sink cooling
• Charging efficiency

What you will learn

The Seebeck effect, waste heat recovery, DC-DC conversion and energy harvesting.

Tools and notes

Arduino, INA219, boost converter, thermocouples, Excel. Do not exceed the rated temperature of the modules, and handle hot parts with care.

Resume points from this project

• Built and tested Thermoelectric Generator (TEG) Waste Heat Harvester; objective: measure the power generated by TEG modules at different temperature differences and see how well it can charge a battery.
• Measured and analysed open-circuit voltage and power vs temperature difference and maximum power point; wrote the report and presented the results in a viva. Add your own numbers: [x].

Replace [x] with your own measured results. Write only what you really did.
