Description
図1は、本発明の実施の形態による車両100に搭載される蓄電装置で、異常検出回路の構成と共に簡略化して、ブロック回路図として組み合わせたものを示している。
ボディアース110とインバータ109との間の抵抗112の抵抗値1MΩに到達しない短絡状態では、差動アンプ104cからの出力値である漏電検出電圧V1が、一定となり、V1=sell(Vsellは、漏電しているキャパシタセル102aまでのGND電位に接続された端部からの電位差)となる。
図5は、時間軸を横軸として、電圧の変動を示した波形図である。
図10は、異常検出の処理順序を説明するフローチャートである。
従って、モジュール102Lの両方の極端部に位置するキャパシタセル102a,102aから得られるモジュール電圧Vmlが検出されて、熱交換部103Lの漏電検出電圧V1が測定されると、HV−ECU105によって、これらの値が対比される。
図1、図2を参照して、本実施の形態に示される車両100は、複数のキャパシタセル102aが積層されたモジュール102L,102Rを含むキャパシタ101と、キャパシタ101内のラミネートセルからなる蓄電部に隣接配置されて、GND電位でボディアース110に接続された熱交換部103L,103Rを含むラジエータ103とを備えている。
