Abstract
Description
上記構成により、ガス配管のためにキャビンから引き出す引出穴を新たに開口させる必要が無く、ハーネス用の引出穴を兼用することで、製造コストを低減しながら配管作業を簡素化できる利点が得られる。とくに、ハーネスを配線する工程と、ガス配管を配管する工程とを同時に行うことで、作業の効率化を図りながら、キャビン内に配置されるサブバッテリの電池セルから排出されるガスを、確実にキャビンの外部に排出できる。
これにより、サブバッテリの電池セルから発生したガスを排出するための独立したガス排出用の配管が不要となり、製造コストを低減しながら、キャビン内に配置されるサブバッテリの電池セルから排出されるガスを、確実にキャビンの外部に排出できる。
これにより、サブバッテリの電池セルから排出されて収納ケースに充満されるガスを、最も簡単な構造でキャビンの外部に排出できる。
これにより、収納ケースから排出されるガスを漏れないように確実にキャビンの外部に排出できる。とくに、走行等によって車両が上下に振動する環境においても、収納ケースの内部とキャビンの外部とをガス排出筒部を介して確実に連通できる。
これにより、ガス排出部を通過するガスをスムーズにキャビンの外部に排気しながら、キャビン外に排出されたガスが収納ケースに逆流するのを確実に防止できると共に、外部からの異物や湿気が収納ケースの内部に流入するのを有効に防止できる。
上記構成により、高温環境下でも優れた特性を示す蓄電を可能としつつ、ニッケル水素電池から排出されるガスを、安全に排出でき、安定して利用できる。
これにより、ハーネスを配線する引出穴をガス配管の配管に兼用することにより、ガス配管を挿通させるための専用の貫通孔を開口することがなく、しかも、配管の効率化を図りながら、キャビン内に配置されるサブバッテリの電池セルから排出されるガスを、確実にキャビンの外部に排出できる。
これにより、サブバッテリの電池セルから発生したガスを排出するための独立したガス排出用の配管が不要となり、製造コストを低減しながら、キャビン内に配置されるサブバッテリの電池セルから排出されるガスを、確実にキャビンの外部に排出できる。
