Description

そして、本発明に係るバスバモジュールにおいて、複数の前記バスバは、前記電池モジュールに対する組付け位置の基準となる１つの基準バスバと、前記基準バスバ以外の残りのバスバと、に大別され、前記基準バスバを保持する前記保持孔については、挿入された前記保持体の前記配列方向への相対移動を規制することで、前記基準バスバの前記フラットケーブルに対する少なくとも前記配列方向への相対移動が規制されるように形成することを特徴としている。
In the bus bar module according to the present invention, the plurality of bus bars are broadly classified into one reference bus bar that serves as a reference for an assembly position with respect to the battery module, and the remaining bus bars other than the reference bus bar. Regarding the holding hole for holding the bus bar, by restricting relative movement of the inserted holding body in the arrangement direction, relative movement of the reference bus bar with respect to the flat cable is restricted at least in the arrangement direction. It is characterized by forming as follows.

また、上記目的を達成する為、本発明に係る電池パックは、複数の電池セルから成る電池モジュールと、複数の前記電池セルを直列又は並列に電気的に接続させるバスバモジュールと、を備え、前記バスバモジュールは、前記電池モジュールにおける一列に並べられた電極端子群の電極端子が挿通される貫通孔を有し、前記電極端子群におけるそれぞれの電極端子の配列方向に沿って配列された複数のバスバと、複数の前記バスバに対して電気的に接続される導体部、及び、複数の前記バスバを保持する絶縁性の保持部を有するフラットケーブルと、を備え、前記バスバは、前記フラットケーブルに取り付けるための保持体を有し、前記保持部は、挿入された前記保持体の前記配列方向への相対移動を許容することで、前記バスバの前記フラットケーブルに対する前記配列方向への相対移動を許容する保持孔を前記バスバ毎に有することを特徴としている。そして、本発明に係る電池パックにおいて、複数の前記バスバは、前記電池モジュールに対する組付け位置の基準となる１つの基準バスバと、前記基準バスバ以外の残りのバスバと、に大別され、前記基準バスバを保持する前記保持孔については、挿入された前記保持体の前記配列方向への相対移動を規制することで、前記基準バスバの前記フラットケーブルに対する少なくとも前記配列方向への相対移動が規制されるように形成することを特徴としている。
In order to achieve the above object, a battery pack according to the present invention includes a battery module composed of a plurality of battery cells, and a bus bar module that electrically connects the plurality of battery cells in series or in parallel. The bus bar module has a through hole through which the electrode terminals of the electrode terminal group arranged in a row in the battery module are inserted, and a plurality of bus bars arranged along the arrangement direction of the electrode terminals in the electrode terminal group. And a flat cable having a conductive portion electrically connected to the plurality of bus bars and an insulating holding portion for holding the plurality of bus bars, and the bus bar is attached to the flat cable. A holding body for allowing the relative movement of the inserted holding body in the arrangement direction to permit the frame of the bus bar to move. The holding holes to allow relative movement to the arrangement direction with respect-through cable is characterized by having for each of the bus bar. In the battery pack according to the present invention, the plurality of bus bars are roughly divided into one reference bus bar that serves as a reference for the assembly position with respect to the battery module, and the remaining bus bars other than the reference bus bar. Regarding the holding hole for holding the bus bar, by restricting relative movement of the inserted holding body in the arrangement direction, relative movement of the reference bus bar with respect to the flat cable is restricted at least in the arrangement direction. It is characterized by forming as follows.
