Description
図1は、第1の実施形態における電力伝送システム10が置かれる環境の一例を示す模式図である。電力伝送システム10は、送電装置100、受電装置200、及びコイルCLを備える(図2参照)。送電装置100は、受電装置200に対して、複数のコイルCLを介して、磁気共鳴方式に従ってワイヤレス(無接点)で電力伝送する。配置されるコイルCLの数は、n個であり、任意である。
図7は、第2の実施形態における電力伝送システム400が置かれる環境の一例を示す模式図である。図7において、第1の実施形態と共通する部分については同じ符号を用いている。また、説明の簡潔のために、第1の実施形態と共通する部分については、適宜、説明を省略する。
次に、第1,第2の実施形態の電力伝送システム10,400が置かれる環境の変形例について説明する。ここでは、電力伝送システム10として例示するが、電力伝送システム400についても同様である。
コイルCLの線材として例えば銅が用いられている場合、銅は比重が値8.9程度であるので、水に対してかなり重い。また、コイルCLに対して連結体30(例えばロープ)や支柱31が接続されると、システム構造物を運搬する場合の重量は更に大きくなる。
以上のように、本開示における技術の例示として、第1,第2の実施形態を説明した。しかし、本開示における技術は、これに限定されず、変更、置き換え、付加、省略などを行った実施形態にも適用できる。
