Description
〔第1実施形態〕
初めに第1実施形態について説明する。本第1実施形態に係る非接触給電システムは、図1に示すように、地面に埋設された地上給電装置S及び該地上給電装置Sから給電を受ける移動車両Mを備えている。このような非接触給電システムは、非接触給電方式の1つである磁界共鳴方式に基づいて地上給電装置Sから移動車両Mに電力を非接触給電する。
整流回路2は、入力端が電源1に接続され、出力端が給電回路3に接続されている。このような整流回路2は、電源1から供給される交流電力を整流して直流電力に変換し、該直流電力を給電回路3に出力する。
最初に、非給電時における移動車両M及び地上給電装置Sの動作について説明する。移動車両Mの受電用制御部15は、非給電時(例えばユーザによる移動車両Mの通常運転時)に、充電回路13を停止させる。一方、地上給電装置Sの給電用制御部7は、非給電時、つまり給電対象である移動車両Mが駐停車位置に停車していない時に、給電回路3を停止すると共に、柔軟性カバー5が完全に収縮するように給電用ガス給排気機構6に柔軟性カバー5内のガスを排気させる。
次に、第2実施形態に係る非接触給電システムについて説明する。
本第2実施形態に係る非接触給電システムは、第1実施形態の柔軟性カバー5に代えて柔軟性カバー25を備え、また第1実施形態の給電用ガス給排気機構6に代えてガス給排気機構26を備えるものである。これ以外の構成要素については第1実施形態と同様である。よって、第2実施形態において第1実施形態と同様の構成要素については説明を省略する。
地上給電装置Sの給電用制御部7は、不図示の音波センサあるいは光センサ等の位置センサの出力から地上給電装置Sの上方に移動車両Mが移動してきたことを検知すると、柔軟性カバー25が完全に膨張するように給電用ガス給排気機構26にガスを供給させる。
(1)上記第1,2実施形態では、柔軟性カバー5、25の内部空間が複数の領域(領域5a〜5dあるいは領域25a、25b)に分割されて、給電用ガス給排気機構6、26によって時間をずらしながら各領域にガスを供給することによって、異物の除去を実現したが本発明はこれに限定されない。
