Description
Claims (5)
- 内圧を解放するための安全弁を備えた二次電池からの電力により駆動される電動車両を制御するための電動車両制御装置であって、
前記二次電池の内圧を直接的又は間接的に測定するセンサと、
前記センサが測定した前記二次電池の内圧が、通常時の前記二次電池の内圧よりも高く設定された内圧異常判定閾値を超えた後、前記内圧異常判定閾値よりも低く設定された開弁判定閾値を下回った場合には、前記安全弁が開いたと判定し、前記センサが測定した前記二次電池の内圧が、前記内圧異常判定閾値を超えたことがないにもかかわらず前記開弁判定閾値を下回った場合には、前記安全弁が開いたこと以外の異常が発生したと判定する内圧状態判定手段と、
を備える電動車両制御装置。 - 前記センサが測定した前記二次電池の内圧が、前記内圧異常判定閾値を超えている間、前記二次電池への充電を停止しつつも、前記二次電池から所定の負荷に電力供給が行われるよう制御を行うことで、前記二次電池に蓄積された電気エネルギーが放出されるようにする電池制御手段、
を更に備える請求項1に記載の電動車両制御装置。 - 前記所定の負荷は、前記電動車両を駆動するための車両駆動用モータであることを特徴とする請求項2に記載の電動車両制御装置。
- 前記電池制御手段は、前記安全弁が開いたと前記内圧状態判定手段が判定した場合、前記二次電池への充電の停止に加え、前記二次電池から前記車両駆動用モータへの電力供給も停止する、ことを特徴とする請求項3に記載の電動車両制御装置。
- 前記所定の負荷として、前記二次電池からの電力を消費するための外部抵抗を付加したことを特徴とする請求項2に記載の電動車両制御装置。
