Description
本願は、2011年10月13日に日本国に出願された特願2011-225912号に基づき優先権を主張し、その内容をここに援用する。
このバスバーモジュールは、バスバーと前記バスバーを支える樹脂体とからなり、電池モジュールの接続端子と制御基板の接続端子とを接続する。
なお、バスバーモジュールと制御基板とは合わせて電源制御装置として機能する。つまり、上述のようなバッテリシステムは、電池モジュールの上に電源制御装置が設置された構成を有している。
続いて、バスバーモジュールの上に制御基板を設置する。このとき、例えばバスバーモジュールが備えるリードピンを制御基板の接続端子に半田付けすることで、バスバーモジュールと制御基板とが電気的に接続される。
すなわち、(1)本発明の一態様に係る電源制御装置は、電池モジュールの電圧を制御する制御基板と、上記制御基板と上記電池モジュールとを電気的に接続するバスバーモジュールと、を備え、上記制御基板と上記バスバーモジュールとは積層配置されており、上記バスバーモジュールの上記電池モジュールとの接続端子は、上記制御基板の側から見て露出されている。
この電池102は、不図示の固定台に固定されて複数備えられている。これらの電池102は、同一姿勢にて配列されている。端子台103は、電池102の接続端子を固定する台であり、電源制御装置1が電池102と電気的に接続するための接続端子を備えている。これらの端子台103が備える接続端子は、予め定められた配置パターンにて端子台103の上面に設けられている。なお、端子台103の上面に設けられる接続端子は、電池モジュール101を電源制御装置1と電気的に接続するための接続端子として機能するため、以下の説明においては、端子台103の上面に設けられる接続端子を電池モジュール101の接続端子と称する。
バスバー2aは、電池モジュール101の接続端子の数の分だけ設けられている。また、全てのバスバー2aが接続端子2cを有している。これらのバスバー2aの接続端子2cは、樹脂体2bの周囲と同じ高さになるように配置されており、電池モジュール101の接続端子に対応する位置に設けられている。
なお、各接続端子2cには、貫通孔2eが設けられている。これらの貫通孔2eを挿通する不図示のネジによってバスバーモジュール2が電池モジュール101に固定され、接続端子2cが電池モジュール101の接続端子と電気的に接続される。
これらのリードピン2dが樹脂体2bの接続端子と半田付けにより接合されることで、バスバーモジュール2は制御基板3と電気的に接続される。
この制御基板3は、図2Aに示すように、バスバーモジュール2の樹脂体2bと略同一の略長方形に形状設定されている。制御基板3は、バスバー2aの接続端子2cが露出されるように周縁部に複数の切欠き3aを有している。このように制御基板3が切欠き3aを有することによって、本実施形態の電源制御装置1においては、バスバーモジュール2の電池モジュール101との接続端子2cが制御基板3側から見て露出されている。
また、制御基板3は、バスバー2aのリードピン2dと重なる領域に各リードピン2dに対応したスルーホール3b(図1参照)を備えている。このようなスルーホール3bにリードピン2dが挿通され、このリードピン2dと制御基板3のランドとが半田付けにて接合されることで、バスバーモジュール2と制御基板3とが電気的に接続されている。
電池モジュール101は、複数の電池102を不図示の固定台に設置すると共に電池に対して端子台103を固定することで組み立てられる。
電源制御装置1は、バスバーモジュール2と制御基板3とをネジ4によって固定すると共に、リフロー方式の半田付けによってリードピン2dと制御基板3とを接合する。
その後、カバー110を組み付けることによって、バッテリシステム100が組み立てられる。
このため、制御基板3にスルーホール3bを設けることにより、開口部2fに露出されたリードピン2dを前記スルーホール3bに挿通することができる。スルーホール3bにリードピン2dが挿通されることによって、多少の振動が加わった場合であってもリードピン2dと制御基板3とが乖離することを防げる。そのため、本実施形態の電源制御装置1によれば、上記構成を採用することで、バスバーモジュール2と制御基板3との電気的に接続を強固なものとすることができる。
また、上記実施形態においては、屈曲部2gが鉛直方向に屈曲された構成を採用した。
しかしながら、バスバーの一部を水平方向に屈曲し、この屈曲された部位を屈曲部とすることも可能である。さらに、水平方向及び鉛直方向にバスバーの一部を屈曲し、この屈曲された部位を屈曲部とすることも可能である。
