Experimental research on thermoelectric application characteristics of thermobattery

Abstract

Abstract In this work, experimental research was carried out to investigate the conversion output characteristics of thermobattery. The results showed that under the same temperature difference, the open-circuit voltage of the thermobattery showed a tendency of first increasing and then decreasing with the increase of hot end temperature. Under hot-end temperature of 95°C, the output open-circuit voltage reached the maximum. In addition, there was a maximum output point for the thermobattery. Regarding the thermobattery (TGM-287-1.4-1.5), its output power reached the maximum when the load resistance was 9Ω. This research provides a theoretical and experimental basis for the optimal design of thermoelectric power generation system.
