| Abstract(J) | EV車の航続距離向上には，空調に伴うエネルギーロス低減も重要と考える．本研究では，EV車の断熱特性を詳細に把握するため，実車および模擬試験を用いた熱流測定と解析を実施した．さらに，多重壁構造を有する車室壁における入・放熱挙動に着目し，壁内部の温度分布や外気流による熱移動の影響解明を試みたので，これらの知見について報告する． Translation |
| Abstract(E) | Improvement of the driving range of electric vehicles (EVs) requires not only advances in battery systems but also the reduction of energy losses associated with cabin climate control. In the present study, heat-flux measurements and thermal analyses were performed using both an actual EV and a controlled experimental apparatus in order to obtain a detailed understanding of the thermal insulation characteristics of EV cabins. Particular attention was directed toward the heat-gain and heat-release behavior within multilayer cabin-wall structures. The internal temperature distribution and the influence of external airflow on heat transfer through the wall were examined, and the resulting findings are reported herein. |
