Description
非接触給電システムは、1次側の非接触給電装置(送電側)と2次側の非接触給電装置(受電側)とを対向配置して構成される。電力を供給する側である1次側の非接触給電装置と電力を受ける側の2次側の非接触給電装置は、コイルの部分の要素はほぼ同じ要素で構成されており、ここでは、一方の側について説明するが、他方の側も同様であることは言うまでもない。
以下、本発明に係る第1実施形態のコイル20を図1、図2を参照して説明する。図1は本発明に係る第1実施形態の渦巻き状のコイル(パラハイブリッド巻)の平面図、図2は要部(区間P1~P4の中の区間P1)の拡大図である。
換言すると、このコイル20は、末端が結合される1組のリッツ線21、22を平坦に並べて巻回する中で、外周側のリッツ線22を一定間隔で巻回し、リッツ線22間に、内周側のリッツ線21が隣接するリッツ線22に当接と離間を規則的に繰り返すように蛇行させて配置したものである。規則的とは一定の長さや間隔、角度、一周のうちのある区間で折り曲げ、折り返すことを言う。
このコイル20の場合、渦巻状の溝が形成された巻回治具に2本のリッツ線21、22を順に嵌め込んでいくことで、2本のリッツ線21、22を平面的に渦巻き状に巻回する。
この結果、既定の寸法および形状(2本1組のリッツ線21、22を既定の外形、内形の範囲に隙間を設けて並べて巻回した形状)、既定の電気的性能に適合し、低コストでかつハンドリング性のよい非接触給電装置およびコイルを提供することができる。
次に、図4を参照して第2実施形態を説明する。図4は第2実施形態のコイル(車両側)を示す平面図である。なお第2実施形態において第1実施形態と同じ構成要素には同一の符号を付しその説明は省略する。
