Description
これによれば、外部交流電源から蓄電池への充電と、交流電源ソケットの使用が重なった場合、外部交流電源への過大な電力負荷を防止し、電力損失を最小化する、制御器を提供できる。
これによれば、外部交流電源から蓄電池への充電と、交流電源ソケットの使用が重なった場合、利用者に注意を促すことができる。
これによれば、交流電源ソケットの使用中に外部交流電源から蓄電池への充電が開始された場合や、外部交流電源から蓄電池への充電が行われているときに交流電源ソケットが使用され始められた場合でも、外部交流電源への過大な電力負荷を防止し、電力損失を最小化する、制御器を提供できる。
これによれば、外部交流電源から蓄電池への充電と、交流電源ソケットの使用が重なった場合でも、外部交流電源への過大な電力負荷を防止し、電力損失を最小化する、交流電流供給方法を提供できる。
(第一実施例)
図1は、本発明に係る第一実施例における交流電流供給装置1のブロック図を示す。この交流電流供給装置1は、車両2に備えられている。車両2は典型的には自動車であるが、これに限られず、交流電流供給装置1は、電車等を含む車両一般、船舶、航空機などの移動装置、自ら動くことはないが収容物のために蓄電池を備えたコンテナ、停電の時のために蓄電池を備えた自動販売機など、蓄電池を備え、その蓄電池から他の電気器具に電力を提供できる物すべてに適用できる。
交流電流供給装置1は、交流電源接続端子10が外部交流電源3に接続されると、電力の供給を受けることのできる状態となる。交流電源接続端子10からの交流電流は、第二スイッチ70を経て、交流−直流変換器20に至る。
交流−直流変換器20により変換された直流電流は、蓄電池30に蓄電される。蓄電池30は、特に限定されず、リチウムイオン蓄電池、ニッケル水素蓄電池、鉛蓄電池、ニッケルカドミウム蓄電池、ナトリウム硫黄電池などであってよい。
また、交流電流供給装置1は、漏電に備え、漏電ブレーカ120を備えてもよい。
また、第一スイッチ60、第二スイッチ70、第三スイッチ80の導通と遮断の条件について、利用者が操作画面において選択することができるようにしてもよい。
S10にて、制御器90は、交流電源接続端子10が外部交流電源3に接続されているかどうかチェックする。接続されている場合、S20にて、制御器90は、交流電源ソケット50にプラグが挿入されているかどうかチェックする。プラグが挿入されていない場合、S30にて、制御器90は、第二スイッチ70を導通し、他のスイッチを遮断する。その結果、外部交流電源3から蓄電池30へ充電が開始される。
さらに、本発明において、第二スイッチ70および第三スイッチ80が同時に導通しない。これにより、交流電源ソケット50の使用と蓄電池30への充電が同時に発生せず、車両2における消費電力が外部交流電源の電力供給容量を超えない。
なお、交流―直流変換器20から蓄電池30への電流量を外部交流電源3の電力供給容量を超えないように制限することで、第二スイッチ70および第三スイッチ80が同時に導通させる。このとき、交流電源ソケット50の使用と蓄電池30への充電を同時に発生させることができる。
