Description
そして、本発明においては、リードに形成された湾曲部は、セル間の間隙へ突出している。セル間の間隙に湾曲部が配置されるため、湾曲部の形成によりセル外周部分に出っ張りが生じることを防ぐことができる。
そして、本発明によれば、湾曲部をセル間の間隙へ突出させることにより、セル外周部分に出っ張りのないコンパクトな構造にすることができる。
図1は本発明に係る例えばリチウムイオン電池などの電池パックの分解斜視図であり、例えば外装がアルミニウム製の複数のセル10(本実施の形態では2個)がケース6,8に収納されている。2個のセル10,10は、図示しない例えばプラスチックなどの絶縁性のスペーサを挟んで離隔配置され、両セル10,10の正極は板状の正極リード12に接続され、負極は板状の負極リード22に接続され、正極リード12及び負極リード22は保護回路基板18に接続されている。

- 四角形の板状を有する複数のセルを、スペーサを介在させて、平面が対向する状態で積層し、各セルをリードで接続し、ケースに収納した電池パックにおいて、
各セルの対向する平面の周縁にR部を備え、
前記リードに、前記R部間に突出する湾曲部が形成されていることを特徴とする電池パック。 - 前記湾曲部は、突出した先端部分と、該先端部分の両端側の根元部分とを備え、
前記湾曲部の前記先端部分及び前記根元部分の曲率半径は、前記リードの厚みの2倍以上、4倍以下であることを特徴とする請求項1記載の電池パック。
