Abstract
Description
ここで開示される組電池では、該組電池内の隣り合う2つの前記単電池は、前記電池ケースの互いに対向する面に該電池ケース内で発生したガスを排出するガス排出弁がそれぞれ設けられている。そして、前記隣り合う2つの単電池が備える前記電池ケースにおいて、互いに対向する面にそれぞれ設けられた前記ガス排出弁は、前記単電池の配列方向から見たときに、相互に重ならない位置に配置されていることを特徴とする。
リチウムイオン二次電池を構成する蓄電素子は、ここでいう「単電池」に包含される典型例であり、そのような単電池を複数備えて成るリチウムイオン二次電池モジュールは、ここで開示される「組電池」の典型例である。
上記構成の本発明の組電池では、電池ケースの互いに対向する面にそれぞれ設けられたガス排出弁が配列方向から見て相互に重ならない位置に配置されている。このため、一方の単電池のガス排出弁から排出されたガスが隣接する他方の単電池のガス排出弁に吹き付けられにくく、また双方のガス排出弁が同時に作動した場合でも互いのガス排出が阻害されにくい。従って、本構成の組電池では、上記のような不具合が生じにくく、信頼性の高い組電池を提供することができる。
特に限定することを意図したものではないが、以下、電池構成としてリチウムイオン二次電池を例にして本発明を詳細に説明する。
他方、上記の通り、本実施形態に係る組電池200では、電池ケース50の互いに対向する面にそれぞれ設けられたガス排出弁60は、配列方向Zから見て相互に重ならない位置に配置されているので、一方の単電池のガス排出弁から排出されたガスが隣接する他方の単電池のガス排出弁に吹き付けられにくく、また双方のガス排出弁が同時に作動した場合でも互いのガス排出が阻害されにくい。従って、本構成の組電池では、上記のような不具合が生じにくく、信頼性の高い組電池を提供することができる。
