Description
本願は、2014年3月18日に日本国に出願された特願2014−55053号と、2014年4月11日に日本国に出願された特願2014−81973号と、に基づき優先権を主張し、その内容をここに援用する。
本発明の第7の態様は、上記第4〜第6のいずれかの態様において、上記情報は、上記二次電池の充電電圧あるいはインピーダンスである。
本発明の第10の態様は、上記第1〜第9のいずれかの態様において、上記給電制御部は、上記インバータ回路のスイッチング周波数を調整する。
本発明の第11の態様は、上記第1〜第10のいずれかの態様において、上記給電制御部は、上記インバータ回路のオン/オフのデューティ比を調整する。
本発明の第12の態様は、上記第1〜第11のいずれかの態様において、上記給電制御部は、上記インバータ回路における2つのスイッチング素子が直列接続された2つのレグのスイッチングの位相差を調整する。
本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、給電装置Sと受電装置Rによって構成されている。上記給電装置Sは、図示するように、給電整流回路1、インバータ回路2、給電共振回路3、給電通信部4(取得部)、スイッチング周波数設定部5、スイッチング制御部6及び記憶部10から構成されている。
また、本実施形態によれば、給電開始後に時々刻々と変化する充電率(SOC)を受電装置Rから順次取得してスイッチング周波数fを変化させるので、バッテリBに対するリアルタイムかつ細かな充電制御を実現することができる。
(1)上記実施形態では、後期充電期間においてスイッチング周波数fが充電率(SOC)の増加に伴って定常スイッチング周波数f0から直線的に漸次大きく変化するようにしたが、本発明はこれに限定されない。例えば、図2の(a)に二点鎖線で示すように、スイッチング周波数fが充電率(SOC)の増加に伴って定常スイッチング周波数f0から直線的に漸次小さく変化するようにしてもよい。また、直線的に漸次変移することに代えて段階的にステップ状に変化させてもよい。
