Abstract
Description
さらに以下に示す実施形態は、本発明の技術思想の具体例を示すものであって、本発明を以下に限定するものではない。また、以下に記載されている構成部品の寸法、材質、形状、その相対的配置等は、特定的な記載がない限り、本発明の範囲をそれのみに限定する趣旨ではなく、例示することを意図したものである。また、一の実施の形態、実施例において説明する内容は、他の実施の形態、実施例にも適用可能である。また、図面が示す部材の大きさや位置関係等は、説明を明確にするため、誇張していることがある。
図1のブロック図に示す電源装置100は、複数の電池モジュール10を直列に接続している。電池モジュール10は、複数の電池1を直列に接続して、保護素子のヒューズ2を電池1と直列に接続している。この電源装置100は、複数の電池モジュール10を直列に接続して、トータル電圧を高くしている。電源装置100のトータル電圧は、各々の電池モジュール10の出力電圧を加算した電圧となる。したがって、電源装置100は、用途に適した出力電圧とするように、直列に接続する電池モジュール10の個数を調整する。たとえば、n個の電池モジュール10を直列に接続して、トータル電圧を電池モジュール10の電圧のn倍にできる。
