Description
[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。
蓄電素子300の構成について、詳細に説明する。蓄電ユニット12が有する蓄電素子300は全て同様の構成を有するため、以下では、1つの蓄電素子300の構成について詳細に説明する。
図5は、本実施の形態に係る蓄電素子300にスペーサ600及び第一接着体710が配置された構成を示す正面図である。具体的には、図5は、蓄電素子300にスペーサ600及び第一接着体710が配置された状態をX軸プラス方向から見た場合の、スペーサ600及び第一接着体710の配置位置を示している。図6及び図7は、本実施の形態に係る蓄電ユニット12内での蓄電素子300の接着、及び、外装体11内での蓄電ユニット12の接着の構成を示す断面図である。具体的には、図6は、外装体11の外装体本体100内に蓄電ユニット12が配置された状態を、蓄電ユニット12の中心位置を通りXZ平面に平行な面で切断した場合の構成を示す断面図である。図7は、外装体本体100内に蓄電ユニット12が配置された状態を、蓄電ユニット12の中心位置を通りXY平面に平行な面で切断した場合の構成を示す断面図である。
本実施の形態に係る蓄電装置10によれば、蓄電ユニット12は、第一蓄電素子301及び第二蓄電素子302の間に、第一蓄電素子301の長側面部311が凹んだ凹部311a内に配置される第一接着体710と、第一接着体710と異なる位置に配置されるスペーサ600と、を有している。第一蓄電素子301の凹部311a内に第一接着体710を配置することで、第一接着体710の厚みを厚くすることができ、かつ、第一接着体710と異なる位置にスペーサ600を配置することで、第一接着体710の厚みをさらに厚くすることができる。特に、第一蓄電素子301及び第二蓄電素子302の間にスペーサ600を配置することで、第一接着体710が圧縮されて厚みが薄くなるのを抑制でき、第一接着体710の厚みを厚い状態で維持することができる。また、第一接着体710が第一蓄電素子301の凹部311a内に配置されることで、第一蓄電素子301が膨れようとした場合に、第一接着体710による第一蓄電素子301及び第二蓄電素子302の接着を剥がそうとする応力が分散される。このため、第一蓄電素子301及び第二蓄電素子302が剥がれるのを抑制できる。これらにより、第一蓄電素子301及び第二蓄電素子302の接着強度を高めることができるため、蓄電装置10の耐振動性または耐衝撃性の向上を図ることができる。
(変形例1)
上記実施の形態の変形例1について、説明する。図8は、本実施の形態の変形例1に係る蓄電素子300にスペーサ601及び第一接着体711が配置された構成を示す正面図である。図8は、図5に対応する図である。
上記実施の形態の変形例2及び3について、説明する。図9は、本実施の形態の変形例2に係る第一接着体712の構成を示す断面図であり、図10は、本実施の形態の変形例3に係る第一接着体713の構成を示す断面図である。具体的には、図9及び図10は、図6に示した第一蓄電素子301及び第二蓄電素子302の上部に対応する図である。
以上、本実施の形態(その変形例も含む)に係る蓄電装置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。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、本発明の範囲には、特許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。
