Abstract
Description
まず、本実施の形態に係る車体下部構造の構成について説明する。
前述のように、フロアパネル14の車両幅方向の両端には、車両前後方向に沿ってロッカ18、20がそれぞれ延在されている。なお、ロッカ18は、ロッカ20と略同じ構成であるため、ロッカ18の説明は割愛する。
電池パック40は、図1及び図3に示されるように、車両前後方向を長手とし且つ車両上下方向に扁平な箱状に形成された電池ケース42と、電池ケース42の内部に収容された複数の電池モジュール72と、を備えており、電池モジュール72は、複数の角型の蓄電池によって構成されている。
次に、本実施の形態に係る車体下部構造の作用及び効果について説明する。
