Description
図1は、実施例1に係る二次電池モジュール100を示す分解斜視図である。なお、以降で上下左右前後という言葉を使用する場合には、図1の右下に記載の方向と対応する方向を指す。
最後に図4を用いて、本発明の変形例を示す。本実施形態では基板8に直接電圧検出用端子9を接続していたが、本変形例では基板ではない板状の樹脂部材11に電圧検出用端子9を固定した上で、その後の配線を電線12を用いて行う。このような構造とした場合であっても、本実施形態と同様の効果を得ることができる。 以上、本発明について簡単にまとめる。本発明の電池モジュール(100)は、複数の電池(1)を並べ、互いにバスバー(7)で接続された電池群と、電池群上に配置された基板(8)と、を備え、バスバー(7)の一部は基板(8)側に突出した突出部(17)を有し、基板(17)は、基板(8)から突出し突出部(17)と嵌り合う嵌合部(16)を有する端子部(9)を備え、突出部(17)と、端子部(9)は、嵌合部(16)との嵌め合いを案内するガイド部(14、15a)を有し、突出部(17)及び端子部(9)の一方は変形部(13)を有する。このような構造にすることによって、前後方向または左右方向、もしくは前後方向及び左右方向の位置決めを簡素化することによって発生する応力を電圧検出用端子9に設けた変形部13によって吸収することができる。したがって、位置決めを簡単に行いつつも、嵌合部16と突出部17との接触をより確実なものにすることができ、溶接信頼性が向上することができる。
