Abstract
【解決手段】
低圧系CPU30から電圧検出回路11に対応するブロックB1に対してブロックの両端電圧値を検出させ、次に電圧検出回路12に対応するブロックB2に対してブロックの両端電圧値を検出させ、その後に再度電圧検出回路11に対応するブロックB1に対してブロックの両端電圧値を検出させる。そして、検出された各両端電圧値が予め定めたブロック電圧の上限値から下限値の範囲外にあるか、ブロックB2と再度検出したブロックB1との両端電圧値の差が所定値以上ある場合は車載バッテリに異常があると判断する。
【選択図】図1
Description

Claims (3)
- 二次電池が複数直列接続された車載高圧バッテリの前記二次電池を少なくとも1つ有した複数のブロック各々に対応して設けられ、かつ前記ブロックの両端電圧値を検出する電圧検出手段を備えた電圧検出装置において、
互いに異なる2つのブロックに対応した電圧検出手段に交互に3回以上前記両端電圧値を検出させて、検出された前記両端電圧値に基づいて前記車載高圧バッテリの異常の有無を判定し、前記車載高圧バッテリの異常の有無を判定後に、順次他の組合せの2つのブロックに対応した電圧検出手段に対応するブロックの両端電圧値を交互に3回以上検出させて、前記車載高圧バッテリの異常の有無を判定する制御手段と、
を備えたものであることを特徴とする電圧検出装置。 - 前記制御手段が、前記2つの電圧検出手段に対応するブロックの両端電圧を検出させた結果、一方の電圧検出手段が検出したブロックの両端電圧値と他方の電圧検出手段が検出したブロックの両端電圧値との差が所定値以上ある場合に前記車載高圧バッテリに異常があると判定することを特徴とする請求項1に記載の電圧検出装置。
- 前記制御手段が、前記2つの電圧検出手段に検出させた両端電圧値のうち少なくともいずれか1つが、予め定めたブロックの両端電圧値の範囲外である場合に、前記車載高圧バッテリに異常があると判定することを特徴とする請求項1または2に記載の電圧検出装置。
