Abstract
Description
特許文献1に開示された電源装置は、複数の電池(二次電池)からなる電池集合体と、該電池集合体に形成される電極列に取り付けられるバスバモジュールと、各電池の電圧を検出する電圧検出端子に一側が接続される電圧検出線と、前記電圧検出線の他側が接続されて各電池の電圧を検出する電池監視ユニットと、を備えて構成されている。電池集合体は、一対のエンドプレートで挟持された状態で拘束バンド等により束ねられて一体化されている。各電池には正極と負極が上部に間隔をあけて突設されており、これらの電池は正極と負極が隣り合うように交互に向きを入れ換えて配置されている。また、バスバモジュールは、隣り合う電池の正極と負極を繋いで電池を直列接続する複数のバスバを収容するバスバ収容部が複数連結されて構成されている。
(1) 複数の電池が互いに異なる極性の電極を隣り合わせて配列された電池集合体と、前記電池集合体の二列の電極列に取り付けられて、各電極列で隣り合う正極と負極をそれぞれ接続する複数のバスバと、前記電池集合体を複数の電池群に分けて構成した各電池群に属する電池の前記電極列に取り付けられる前記バスバを該電池群ごとに保持する複数の保持部材と、前記各電池群に属する電池の電圧を該電池群ごとに監視する複数の電池監視ユニットと、を備える電源装置。
前記各保持部材は、複数連結されたバスバ収容部が前記二列の電極列に対応して前記電池集合体の長手方向に二列並んで構成され、前記各電池監視ユニットが、前記電池集合体の長手方向に二列並んだ前記バスバ収容部の間で、前記電池集合体の短手方向に沿ってこれらバスバ収容部と併設される電源装置。
本発明の一実施形態に係る電源装置は、例えば電気自動車やハイブリッド自動車等に搭載された電動モータに対する電力供給装置として用いることができるが、その用途はこれに限定されるものではない。なお、以下の説明においては、図1に矢印Xで示す方向を前後方向、矢印Yで示す方向を左右方向、矢印Zで示す方向を上下方向という。なお、上下方向については、図1における上方へ向かう方向を上向き(上側)、下方へ向かう方向を下向き(下側)として特定する。ただし、これらの前後方向、左右方向及び上下方向は、例えば電源装置が車載された状態における各方向(例えば、自動車の前後方向、左右方向や上下方向)と必ずしも一致していなくともよい。
また、第一〜第四の電池監視ユニット5a〜5dを保持するためのユニット保持部を第一〜第四の保持部材4a〜4dにそれぞれ一体に形成した場合には、個別の第一〜第四の電池監視ユニット5a〜5dごとに、対応する個別の第一〜第四の保持部材4a〜4dを同時に取り外すことができ、交換作業が容易となる。
[1] 複数の電池(2)が互いに異なる極性の電極(正極21,負極22)を隣り合わせて配列された電池集合体(20)と、
前記電池集合体(20)の二列の電極列(23,24)に取り付けられて、各電極列(23,24)で隣り合う正極(21)と負極(22)をそれぞれ接続する複数のバスバ(3)と、
前記電池集合体(20)を複数の電池群(20a〜20d)に分けて構成した各電池群(20a〜20d)に属する電池(2)の前記電極列(23,24)に取り付けられる前記バスバ(3)を該電池群(20a〜20d)ごとに保持する複数の保持部材(第一の保持部材4a、第二の保持部材4b、第三の保持部材4c、第四の保持部材4d)と、
前記各電池群(20a〜20d)に属する電池(2)の電圧を該電池群(20a〜20d)ごとに監視する複数の電池監視ユニット(第一の電池監視ユニット5a、第二の電池監視ユニット5b、第三の電池監視ユニット5c、第四の電池監視ユニット5d)と、を備える電源装置(1)。

前記各保持部材(4a〜4d)は、複数連結されたバスバ収容部(41)が前記二列の電極列(23,24)に対応して前記電池集合体(20)の長手方向に二列並んで構成され、
前記各電池監視ユニット(5a〜5d)が、前記電池集合体(20)の長手方向に二列並んだ前記バスバ収容部(41,41)の間で、前記電池集合体(20)の短手方向に沿ってこれらバスバ収容部(41,41)と併設される電源装置(1)。
