Description
以下、本発明の第1の実施の形態に係る車両用充電装置の一例を、図1〜図5を参照して説明する。
図1は、本発明の実施の形態に係る車両用充電装置を示す概略構成図である。
図2は、本発明の実施の形態に係る車両用充電装置の使用状態を示す概略構成図である。
図3は、車両用充電装置1の回路構成を車両9側の構成と共に示す回路図の一例である。
車両側コネクタ91は、第1〜第5端子911〜915を有している。車両側コネクタ91が充電コネクタ11に嵌合すると、第1端子911がL端子111に、第2端子912がN端子112に、第3端子913がGND端子113に、第4端子914がC端子114に、第5端子915がP端子115に、それぞれ接続される。第3端子913と第5端子915との間には、抵抗器916が接続されている。抵抗器916の抵抗値は、例えば2700Ωである。
車両用充電装置1は、第1及び第2のリレー21,22に固着による故障が発生していないかを診断する自己診断機能を有している。本実施の形態では、この自己診断機能が、制御部20によって実現される。すなわち、本実施の形態では、制御部20が、第1及び第2のリレー21,22の故障を診断可能な故障診断手段として機能する。なお、第1及び第2のリレー21,22の固着とは、接点部211,221が、コイル部210,220への非通電時にも閉状態となったままになることをいう。
以上説明した第1の実施の形態によれば、以下に述べる作用及び効果が得られる。
図4に示す例では、ステップS20において、電流センサ231の検出信号に基づいて検出した充電電流を積算したが、これに替えて、検出した充電電流の電流値が所定値を超えている場合に、この超えた分の電流値を積算してもよい。この所定値としては、例えば車両用充電装置1の定格出力電流を用いることができる。
次に、本発明の第2の実施の形態について図8を参照して説明する。
図8に示す例では、ステップS20Aにおいて、検出した充電電流及び充電電圧に基づいて得られた充電電力を積算したが、これに替えて、充電電力が所定値を超えている場合に、この超えた分の充電電力を積算してもよい。この所定値としては、例えば車両用充電装置1の定格出力電力を用いることができる。
次に、本発明の第3の実施の形態について図9を参照して説明する。
次に、本発明の第4の実施の形態について図10を参照して説明する。
