| Abstract(J) | モータベンチ等でEVのユニット単体の損失測定は可能だが，種々の車両ファクターがある為，実使用環境下における損失の算出は難しい．今回，EVのユニット毎（コンバータ，インバータ，モータ＋ギヤ等）の損失を車載状態で実測可能な手法を構築し，WLTP条件下での各部の損失割合を計測した結果と今後の課題を報告する． Translation |
| Abstract(E) | Although loss measurement of each EV powertrain component on a motor bench is possible, calculating losses under actual operating conditions is difficult due to various vehicle factors. In this study, we developed a method to directly measure the losses of each component (converter, inverter, motor + gearbox, etc.) of EV powertrain under in‑vehicle conditions. We report the loss distribution under WLTP conditions, as well as the challenges identified for future work. |
