本発明に係る電池モジュールは、電槽の外面の一面上に正極用及び負極用の接続端子が間隔をあけて配置された複数の単電池と、二つ以上の単電池を整列状態で一体的に保持可能に構成された一つ以上の電池ホルダーと、前記単電池の電気的な監視を行う回路基板とを備えた電池モジュールにおいて、前記電池ホルダーは、正極用及び負極用の接続端子を上側にした二つ以上の単電池を隣り合う単電池の接続端子が対峙するように整列状態で支持するアンダーフレームと、単電池の上面と当接するアッパーフレームとを備え、該アッパーフレームは、単電池の正極用の接続端子と負極用の接続端子との間に配置される基板支持部を備えることを特徴とする。なお、ここで「整列配置」とは、列を整えて配置することを意味し、縦方向で一列に整えて配置することや、横方向で一列に整えて配置することを含む他、縦方向又は横方向で複数列にして各列を整えて配置することも含まれる。
Battery module according to the present invention, integrally with the plurality of unit cells connected terminals for the positive and for the negative electrode are arranged at intervals on one side of the outer surface of the container, two or more unit cells in alignment and one or more battery holders held configured to be able to, in the battery module that includes a circuit board for electrically monitoring of the cells, before Symbol battery holder, the connection terminals for the positive electrode and the negative electrode comprises a underframe unit cells connected terminals adjacent two or more unit cells that upward to support in an aligned state so as to face, the upper frame to the upper surface and the abutment of the unit cell, the upper frame, to obtain Bei a substrate support disposed between the connection terminals for connecting terminal and the negative electrode for the positive electrode of the battery cell and said. Here, “aligned arrangement” means arranging the rows in a row, including arranging in a row in the vertical direction, arranging in a row in the horizontal direction, and in the vertical direction. Alternatively, arranging the rows in a plurality of rows in the horizontal direction is also included.
そして、上記構成の電池モジュールは、二つ以上の単電池がアンダーフレームによって隣り合う単電池の接続端子が対峙するように整列状態で支持されるため、二つ以上（複数）の単電池の接続端子が二列で整列することになる。従って、二列をなす正極用及び負極用の接続端子間に配置された基板支持部上に回路基板を配置することで、回路基板も接続端子間に配置されるため、回路基板を配置するスペースを別途確保することなく回路基板を収容でき、サイズアップすることもない。
Then, the battery module having the above structure, since two or more unit cells are supported in an aligned state as connection terminals of the unit cells facing the adjacent the underframe, the unit cells of two or more (multiple) connection terminals will be aligned in two rows. Accordingly, since the circuit board is also arranged between the connection terminals by arranging the circuit board on the board support portion arranged between the connection terminals for the positive electrode and the negative electrode in two rows, a space for arranging the circuit board. The circuit board can be accommodated without securing a separate space, and the size is not increased.
本発明の他態様として、前記アッパーフレームは、前記二つ以上の単電池の正極用及び負極用の接続端子を包囲可能に形成されるとともにアンダーフレームの上端部に連結可能に構成された枠状部と、該枠状部の包囲する領域内で単電池の整列方向に延びて梁状に形成されて該枠状部がアンダーフレームの上端部に連結された状態で単電池の正極用及び負極用の接続端子間にある上部に当接可能な電池規制部とをさらに備え、該電池規制部は、長手方向に延びる中空部又は長手方向に延びて上方が開放した溝が形成され、前記回路基板に電気的に接続されたリード線が前記中空部又は溝内に配線されてもよい。ここで「整列方向」とは、列数に関係なく列の延びる方向を意味する。このようにすれば、回路基板に接続されるリード線を体裁良く収容して回路基板とともにアッパーフレーム（電池ホルダー）に保持させることができる。
As another aspect of the present invention, the upper frame is formed in a frame shape that is formed so as to surround the connection terminals for the positive electrode and the negative electrode of the two or more unit cells and is connectable to the upper end portion of the under frame. parts and, the positive electrode and the negative electrode of the cell in a state in which the frame-shaped portion is formed on the beam-shaped and extends in the direction of alignment of the cells in a region surrounding of the frame-shaped portion is connected to an upper end portion of the underframe anda contactable battery regulation unit to the upper lying between the connection terminals of the use, the battery restricting portion, groove upper is open and extends to the hollow portion or longitudinal extend in the longitudinal direction are formed, the circuit A lead wire electrically connected to the substrate may be wired in the hollow portion or groove. Here, “alignment direction” means the direction in which the columns extend regardless of the number of columns. If it does in this way, the lead wire connected to a circuit board can be stored with good appearance, and can be held with an upper frame (battery holder) with a circuit board.
