Description
例えば、前記バッテリセルは、少なくとも2以上多数のバッテリセルを含み、前記バッテリパックは、前記多数のバッテリセルを相互電気的に連結するためのバスバーをさらに含んでもよい。
例えば、前記結合部と、前記第1接続部及び第2接続部は、一体に形成されてもよい。
例えば、前記結合部は、前記バッテリセルのセンターラインから相対的に遠いバスバーの外側に配置され、前記第1接続部及び第2接続部は、前記バッテリセルのセンターラインから相対的に近いバスバーの内側に配置される。
例えば、前記第1接続部は、前記第1センシング端子をバスバーに対して加圧密着させることができる。
例えば、前記カンチレバー部材の両側には、前記カンチレバー部材を第1接続部の他の部分から分離させるための切開部が形成されてもよい。
例えば、前記第1センシング端子は、前記自由端部を介して、前記カンチレバー部材とバスバーとの間に入り込み、固定端部に向けてスライディング組込まれてもよい。
例えば、前記加圧部は、前記固定端部よりは、自由端部に相対的に近い位置に形成されてもよい。
例えば、前記カンチレバー部材は、バスバーに向けて突出した圧力調節部をさらに含んでもよい。
例えば、前記第2接続部は、前記結合部に連結された一端の固定端部と、前記結合部と連結されていない他端の自由端部と、を含んでもよい。
例えば、前記第2接続部は、前記固定端部から自由端部に行きながら、バスバーからだんだんと遠くなるように、斜めな斜線方向に沿って延長されてもよい。
例えば、前記第2センシング端子は、前記第2センシング端子のスライディング組込みを案内するためのガイドレールの対を含み、前記突出部は、前記ガイドレールの対の間に介在された加圧板上に形成されてもよい。
例えば、前記加圧板の端には、前記第2接続部の組込み位置を整列するための係止爪が形成されてもよい。
前記ケース10bには、安全ベント10’が形成されてもよい。前記安全ベント10’は、相対的に弱い強度に設計され、ケース10b内に、前もって設定しておいた臨界ポイント以上の耐圧がかかれば、破断されながら内部ガスを噴出させる機能を行う。
バッテリセル10の列方向(Z1方向)に沿って、両側には、1対のエンドプレート150が配置される。前記エンドプレート150の一面は、バッテリセル10の外面と向き合うように配置される。さらに具体的には、前記エンドプレート150の一面は、バッテリセル10の外側に配置されたスペーサ50と当接するように組み立てられてもよい。
前記エンドプレート150は、ベースプレート151と、前記ベースプレート151の端から、バッテリセル10と反対になる方向に折り曲げられたフランジ部152,153,155と、を含んでもよい。前記ベースプレート151は、バッテリセル10の外面をカバーすることができるほどの十分な面積に形成される。
バッテリセル10の下部は、サイドプレート140の係止爪140aによって支えられる部分を除き、サイドプレート140から露出され、サイドプレート140から露出されたバッテリセル10の下部を介して、バッテリセル10間に外気の流れを許容し、バッテリセル10の放熱を促進することができる。
本発明のバッテリパックは、バッテリセル10の過熱、過電流、過充電、過放電のような異常状況を捕捉し、バッテリセル10の充放電動作を制御するために、バッテリセル10の温度や電圧のような状態情報を検出するモニタリング動作を遂行する。
前記第1接続部110は、結合部135に連結された一端の固定端部111aと、結合部135と連結されていない他端の自由端部111bと、を有するカンチレバー部材111を含む。前記カンチレバー部材111は、一端の固定端部111aを介して、コネクタ130の結合部135に連結され、他端の固定されていない自由端部111bを含む片手持ち形態を有することができる。
そのように、比較例では、温度測定のための第1センシング端子8の接続と、電圧測定のための第2センシング端子9の接続とがそれぞれ個別になされ、それぞれの接続作業が主にネジ締結方式によるので、作業性が落ち、製品不良が生じる可能性が高くなる。
