Abstract
【解決手段】制御装置60は、システムリレーSR2,リレーRY1,RY2をオンさせる。昇圧コンバータ10は、コネクタ50および電源ラインPL1,PL4を介して供給される交流電圧を整流する。さらに、昇圧コンバータ10は、制御装置60からの信号PWC11に応答して、整流電圧を昇圧し、昇圧された電圧を電源ラインPL2へ出力する。昇圧コンバータ20は、電源ラインPL2から電圧VHを受け、制御装置60からの信号PWC2に応じて電源ラインPL3に電圧VL2を出力する。システムリレーSR2およびリレーRY2がともにオンしているため、バッテリB1,B2は、電源ラインPL3および接地ラインSLに並列に接続される。これにより、バッテリB1,B2が充電される。

Description
の電力線とに電気的に接続される電圧変換部と、第1の蓄電装置と第1の電力線とに接続され、導通状態と非導通状態とを有する第1の接続部と、第1の蓄電装置と電圧変換部とに接続され、導通状態と非導通状態とを有する第2の接続部と、少なくとも電圧変換部と、第1の接続部と、第2の接続部とを制御する制御装置とを備える。制御装置は、第1の電力線に電動車両の外部から交流電力が与えられる場合には、第1および第2の接続部をそれぞれ非導通状態および導通状態に制御するとともに、第2の電力線に与えられる直流電力の電圧値に基づいて、第1および第2の蓄電装置に目標電圧が与えられるように電圧変換部を制御する。
本発明の実施の形態に係る電動車両として、プラグインハイブリッド車(以下、「ハイブリッド自動車」と呼ぶ)を例示する。ただし、モータからの駆動力のみで走行する電気自動車、または燃料電池車により構成されたプラグイン車に搭載される蓄電装置の充電システムに対しても本願発明は適用可能である。
の3つの回転軸がエンジン4、モータジェネレータMG1,MG2の各回転軸にそれぞれ接続される。たとえば、モータジェネレータMG1のロータを中空としてその中心にエンジン4のクランク軸を通すことで動力分配機構3にエンジン4とモータジェネレータMG1,MG2とを機械的に接続することができる。
される。バッテリB1,B2は、たとえばニッケル水素やリチウムイオン等の二次電池である。ただし、バッテリB1(またはバッテリB2)に代えて大容量の電気二重層コンデンサが、充放電可能な蓄電装置としてハイブリッド自動車100に搭載されてもよい。
にそれぞれ接続される(図3参照)。各npn型トランジスタQ11〜Q16は制御装置60からの信号PWM1をベースに受ける。
クを発生するように駆動される。また、インバータ40は、ハイブリッド自動車100の回生制動時、モータジェネレータMG2が駆動軸からの回転力を受けて発電した3相交流電圧を、制御装置60からの信号PWM2に基づいて直流電圧に変換し、その変換した直流電圧を電源ラインPL2へ出力する。
T3,CONT4をそれぞれシステムリレーSR2,リレーRY1,RY2に送り、これらのリレーをオンさせる。昇圧コンバータ10は、コネクタ50および電源ラインPL1,PL4を介して供給される交流電圧を整流する。さらに、昇圧コンバータ10は、制御装置60からの信号PWC11に応答して、整流電圧を昇圧する。そして昇圧コンバータ10は、昇圧された電圧を電源ラインPL2へ出力する。
以下では、npn型トランジスタを単に「トランジスタ」と称することにする。
システムリレーSR1がオフする。
を参照して、昇圧コンバータ20のトランジスタQ5はオン状態に制御され、トランジスタQ6はオフ状態に制御される。これにより、電圧VHは、電圧VD2に等しくなる。バッテリB1の両端の電圧も電圧VD2に等しい。なお、制御装置60はトランジスタQ5をオフ状態に制御し、かつ、トランジスタQ6をスイッチング状態に制御することによって、電圧VD2を昇圧してもよい。制御装置60は電圧VHの値、および電圧VD2の値に基づいてトランジスタQ6のスイッチングの周期およびデューティ比を算出する。そして制御装置60は算出したスイッチング周期およびデューティ比を表わす信号PWC2を生成して昇圧コンバータ20に信号PWC2を出力する。
,RY2およびシステムリレーSR2がオンする。
グ51が接続された場合(ステップS12においてYES)、処理はステップS13に進む。
〜C3 コンデンサ、D1〜D6,D11〜D16 ダイオード、L1,L2 リアクトル、MG1,MG2 モータジェネレータ、N1,N2 中性点、PL1〜PL4 電源ライン、Q1〜Q6,Q11〜Q16 npn型トランジスタ、RY1,RY2 リレー、SL 接地ライン、SR1,SR2 システムリレー、U1,U2 U相コイル、UL1,UL2 U相ライン、V1,V2 V相コイル、VL1,VL2 V相ライン、W1,W2 W相コイル、WL1,WL2 W相ライン。
