Outline of Research at the Start

本研究は、エンジンを搭載する電動車(ストロング/マイルド・ハイブリッド系、発電機搭載EV系)の未利用排気熱から熱電発電方式で回生電力化を行うことで車載電力を補い、エンジン搭載電動自動車における~4%以上の燃費改善(CO2削減) に資する取組みである。本研究では、軽量で資源豊富、かつ生産時および廃棄時において環境低負荷な熱電変換材料Mg2Siの現状の基本性能を基にして、「車載用小型排気熱発電システム」の実用化に資する要素技術(熱伝達機構改善、熱電モジュールに整合した熱交換器、車載熱電池専用 DC-DC電力変換)の基礎開発を行う挑戦的取組みである。

Outline of Final Research Achievements

By converting unused automotive exhaust heat in the medium temperature range (<600 ° C) into regenerative power using a thermoelectric power generation system, improving fuel efficiency (CO2 reduction) of electric vehicles equipped with a power generation engine is effective in reducing carbon.
We conducted research and development to operate the thermoelectric (TE) power generation system effectively in automobile applications and produced results.
(1) Develop a thermoelectric power generation module structure that introduces a ceramic multilayer board with a variable heat conduction function; (2) Develop a heat exchange/heat conduction mechanism with a built-in temperature control function that does not exceed the durable temperature of the TE power generation (TEG) module from the engine exhaust system; (3) Develop circuit technology that converts the power generated by the TEG module into DC-DC power conversion (specification for TE batteries) with high conversion efficiency.
