Experimental Investigation on Thermoelectric Generator for Battery- Charger Based Oven

Abstract

In this research paper, thermoelectric generator (TEG) module was embedded inside the oven to harvest electrical energy from heat waste of the kitchen oven. The development of experimental setup was investigated in closed-circuit from room temperature rise to 150°C in 60 min using kitchen oven with custom-made aluminum heatsink with built-in water-cooling tank attached on the TEG module. The maximum voltage output was generated about 1.87V in single TEG module where gradient of TEG was measured about 0.0337V/°C. The harvested output of voltage was demonstrated by charging a single lithium battery ‘AA’ in 110 mins for full-charged and it was able to power a LED torch light.
