【0014】
図2は,図1の電池間接続板の部分拡大図である。
図において、10は電池間接続板9の一部を構成する板状の絶縁材、11はこの絶縁材10に埋め込まれた銅板等の導電性の材料からなり、蓄電池1〜3の端子に対応した位置に貫通孔11aを有する導電部、12は導電部11と電気的に接触するように絶縁材10の両側に埋め込まれ、その一端が外部に突出して接続ケーブル5を介して制御装置8と接続するための接続用のスタッドである。また、3aは蓄電池3の接続用端子であって、この接続用端子3aの部分が導電部11の貫通孔11aに挿入される。13は蓄電池3の接続用端子3aの端部に締結固定されて電池間接続板9の導電部11と蓄電池3の接続用端子3aを接続するためのナットである。

【0019】
例えば、蓄電池1〜3の+側の接続用端子と−側の接続用端子は導電部11を介して導電接続部材14により相互に直列接続され、この直列接続の一端に位置する+側の導電部11は接続用スタッド12および接続ケーブル4を介して制御装置8の+側の電源端子に接続され、同様に、直列接続の他端に位置する−側の導電部11は接続用スタッド12および接続ケーブル5を介して制御装置8の−側の電源端子に接続される。
