Abstract
Description
これによれば、蓄電装置の外部端子は、スペーサの端子台と一体に形成されている。このように、外部端子をスペーサの端子台と一体形成することで、部品点数を低減できる。これにより、簡易な構成の蓄電装置を実現できる。
これによれば、バスバーを内部に配置するスペーサは、第一方向において、端部に配置されるエンドスペーサである。このように、バスバーを支持するスペーサとして、エンドスペーサを利用することで、簡易な構成の蓄電装置を実現することができる。
[1 蓄電装置10の全般的な説明]
まず、蓄電装置10の構成について、説明する。図1は、本実施の形態に係る蓄電装置10の外観を示す斜視図である。図2は、本実施の形態に係る蓄電装置10を分解した場合の各構成要素を示す分解斜視図である。
次に、蓄電素子100の構成について、詳細に説明する。図3は、本実施の形態に係る蓄電素子100の構成を示す斜視図である。具体的には、図3は、図2における蓄電素子100から中間スペーサ200や接着層510、520、530が取り外された状態を拡大して示す斜視図である。図2における16個の蓄電素子100は、全て同様の構成を有しているため、以下では、1個の蓄電素子100について説明する。
次に、エンドスペーサ300及び端子部材900の構成について、詳細に説明する。図4は、本実施の形態に係るエンドスペーサ300及び端子部材900の構成を示す斜視図である。具体的には、図4は、図2におけるX軸プラス方向側のエンドスペーサ300を、外部端子910を有する端子部材900とともに示す斜視図である。図5は、本実施の形態に係るエンドスペーサ300の端子台320及び端子部材900の構成を示す斜視図である。具体的には、図5の(a)は、図4に示した端子台320及び端子部材900の構成を拡大して示す拡大斜視図であり、図5の(b)は、端子部材900の構成を示す斜視図である。図6は、本実施の形態に係る蓄電素子100、エンドスペーサ300、エンド部材400、バスバー800及び端子部材900の位置関係を示す斜視図である。図2において、X軸プラス方向側のエンドスペーサ300等とX軸マイナス方向側のエンドスペーサ300等とは、YZ平面に対して対称な形状を有しているため、X軸マイナス方向側のエンドスペーサ300等についての説明は、省略する。
以上のように、本実施の形態に係る蓄電装置10によれば、蓄電素子100に接続されるバスバー920は、少なくとも一部が、エンドスペーサ300の内部に配置されている。このように、バスバー920の少なくとも一部をエンドスペーサ300の内部に配置することで、バスバー920をエンドスペーサ300で支持できる。これにより、バスバー920を支持するバスバーケース(バスバーフレーム、バスバープレート)等の別部材を設ける必要がないため、簡易な構成の蓄電装置10を実現できる。特に、バスバー920を他の部材(蓄電素子100の電極端子120、蓄電装置10の外部端子910等)に取り付ける際に、バスバー920をエンドスペーサ300の内部で位置規制して、バスバー920が回転等移動するのを抑制できる。エンドスペーサ300は絶縁部材であるため、バスバー920と他の部材(蓄電素子100、サイド部材700、エンド部材400等)との間の絶縁性を向上できる。
以上、本実施の形態に係る蓄電装置10について説明したが、本発明は、上記実施の形態には限定されない。つまり、今回開示された実施の形態は、全ての点で例示であって制限的なものではなく、本発明の範囲は請求の範囲によって示され、請求の範囲と均等の意味及び範囲内での全ての変更が含まれる。
