Description
上記のように、電池、スペーサまたはその両方が基板を接続および支持する主要な手段となり得る。しかし、別の実施形態においては、周辺および仕切りの壁が基板を接続および支持するための1つの方法として、または主要な方法として使用される。ここで図11を参照すると、図1に示されている基板が本発明の一実施形態による、周辺および仕切りの壁を伴って示されている。周辺の壁1110は基板1112に取り付けられている。取付けは基板に壁1110を接着、熱接着または溶融によって、または従来のスナップ締結法、またはファスナー1114による他のファスナーによって行うことができる。周辺の壁1110はいくつかの小片から作ることができ、縁部または隅のコネクタが各小片を接続している。周辺の壁1110はコネクタ1116などのコネクタを含むことができ、それは周辺の壁1110の中に成形されたスロットまたは他のファスナーであってよい。コネクタ1116は、周辺の壁1110と同じ方法で基板1112に取り付けることができる、仕切り壁1118に取り付けられる。図に示すように、仕切り壁1118などの仕切り壁は、それ自身がさらに他の仕切り壁を保持するコネクタを有することができる。
図5は、本発明の技法を使用して、導体520〜530によって1つの電池の電圧の約5倍にまで電圧を上昇させるために直列に接続された5個の電池500〜508を示している(図の明確性を改善するために基板、ブラケット、およびスペーサは図から取り除かれている)。図5の各組の中には1つの電池500〜508だけがあるが、導体520〜530の同じ対に接続され、示されている電池500〜508と同じ極性を使用している組ごとに2つ以上の電池を使用して、単一の電池500〜508の電流のほぼその倍数の電流にまで電流を増加させることができる。一実施形態においては、エンド導体520、530には端子540、542があり、それをねじ端子とするか、または上にねじ込まれるナットが付いた組込み型のねじポストとすることができる。従来の方法で各端子540、542に配線を取り付け、電池からの電力を使用点へ供給することができる。本発明の一実施形態においては、使用点は電気自動車内の電動機とすることができ、そして以下に説明されるように、エンド導体520、530ごとに2つ以上の端子540、542を設けることができる。図において、導体520〜530は各導体520〜530から電流が供給されるすべての電池に集合的に接触するが、個々には、導体520〜530は電池500〜508のすべてに接触するわけではなく、各導体520〜530は導体520〜530の任意の他のものに対して、他とは異なる電位にあることに留意されたい。
本明細書で説明されるような基板およびインサートによって挟まれ、導体によって接続されている電池は、絶縁紙または他の絶縁材料をそれに付加することができ、複数のこのようなアセンブリまたは構造の電池を電気的に相互接続することができる。図6Aは、図5のエンド導体530、520と同様な、構造の異なる2つのエンド導体636、637を示しており、それぞれが、図1〜図5に関して上で説明されたように配置された電池の1つまたは複数の組に結合され、電池、基板、残りの導体および他の構造を示している詳細が図の中では省略され、2つの異なる構造のエンド導体の間の相互接続を示している(構造およびアセンブリという用語は本明細書では互換的に使用されている)。エンド導体636は1つの構造のエンド導体であり、そしてエンド導体637は別の構造のエンド導体であり、これらの構造は拡張可能なコネクタ650を使用して別の構造に直列に電気的に接続されることが意図されている。
液体冷却
一実施形態においては、電池は、小さな、熱伝導性の管によって液体冷却することができ、その管を通して水または他のクーラント、例えば、水、油、または冷たい空気と混合された任意の従来型の不凍液を、ポンプなどの従来の手段によって循環させることができる。
各組の中の電池を空気が間を通ることができる電池間の空間によって空冷することができる。空冷は上記の液体冷却に加えて、またはその代わりに使用することができる。一実施形態においては、基板に追加されるインサートが、以下により完全に説明されるように一体化された冷却用の穴およびマウントを使用して電池を取り付けるために使用される。基板は強度および剛性を与えるためにガラス繊維含入材料から作られるが、さらに、インサートはより良好に電池を保持するために、より柔軟な材料から作られる。基板およびインサートは両方とも空気孔を含んでいて、その中に空気を吹き込むこと、または吸引によって空気をそこから取り除くこと、またはその両方を行うことができる。空気孔をマウントと一体化し、空気を電池間の空間の中に直接に吹き込むことができ、しかもマウントが空冷と干渉しないようにすることができる。
本発明によるアセンブリの一例の部分が、本発明の一実施形態に従って図12Aに示されている。図13は、組立ての方法を記述している。
ここで図14を参照すると、電池を取り付けて電気的に接続する方法が本発明の一実施形態に従って示されている。各電池に対するマウントおよび電池に対する電気的接続のための穴を備えた1つまたは2つまたはそれ以上の基板がステップ1410において提供される。一実施形態においては、そのマウントは基板の中に成形される。もう一実施形態においては、そのマウントは上記のように、基板の中にフライス加工され、ここで図15を参照して説明する。
