Description
好ましくは、上記複数の単位コイルは、車両の幅方向に延びる仮想軸線に対して対称となるように配置される。
出力する。
の制御信号の出力を行なうとともに、車両100および各機器の制御を行なう。なお、これらの制御については、ソフトウェアによる処理に限られず、専用のハードウェア(電子回路)で処理することも可能である。なお、図1においては、車両ECU180が、車両100の走行制御、および給電装置200からの電力の受電制御の両方を行なう構成としているが、制御装置の構成はこれに限定されない。すなわち、車両100が、機器ごとあるいは機能ごとに対応した制御装置を個別に備える構成とすることもできる。たとえば、受電制御を主として行なうための受電ECUを備える構成としてもよい。
てPCU160を制御する。
周波電力を一次電磁誘導コイル230へ供給する。なお、高周波電力ドライバ220が生成する高周波電力の周波数は、たとえば1M〜数十MHzである。
共鳴法では、この「静電磁界」が支配的な近接場(エバネッセント場)を利用してエネルギ(電力)の伝送が行なわれる。すなわち、「静電磁界」が支配的な近接場において、同じ固有振動数を有する一対の共鳴器(たとえば一対のLC共振器)を共鳴させることにより、一方の共鳴器(一次共振コイル)から他方の共鳴器(二次共振コイル)へエネルギ(電力)を伝送する。この「静電磁界」は遠方にエネルギを伝播しないので、遠方までエネルギを伝播する「輻射電磁界」によってエネルギ(電力)を伝送する電磁界に比べて、共鳴法は、より少ないエネルギ損失で送電することができる。
(この段落以降が新規)
図4は、車両に搭載されたコイルユニット101を模式的に示す斜視図である。この図4に示すように、コイルユニット101は、二次共振コイル110と、二次電磁誘導コイル120と、二次共振コイル110に設けられたキャパシタ115とを含む。二次共振コイル110は、複数の単位コイル111,112,113,114を含む。各単位コイル111〜114は、互いに隣り合うように配置されている。
図19は、図17に示す電力給電システムの伝送効率を示すグラフであり、図20は、図18に示す伝送効率を示すグラフである。
