Title (EN) METHOD AND DEVICE FOR DETECTING CHARGED STATE OF BATTERY
(FR) PROCÉDÉ ET DISPOSITIF POUR DÉTECTER L'ÉTAT DE CHARGE DE LA BATTERIE
(JA) 蓄電池充電状態検知方法および蓄電池充電状態検知装置
Abstract:
(EN) A method for detecting the charged state of a battery based on the measurements of open circuit voltage in which the charged state of a battery can be detected precisely regardless of the degradation state of the battery. Internal impedance of a battery is measured, voltage of the battery is measured under stable state, measurement of the battery voltage under stable state is subjected to raising correction depending on the measurement of internal impedance, and then charged state of the battery is determined based on the corrected value of battery voltage under stable state.
(FR) La présente invention a trait à un procédé pour détecter l'état de charge d'une batterie en fonction des mesures d'une tension de circuit ouvert, dans lequel l'état de charge d'une batterie peut être détecté précisément quel que soit l'état de dégradation de la batterie. L'impédance interne d'une batterie est mesurée, la tension de la batterie est mesurée dans un état stable, la mesure de la tension de la batterie dans un état stable est soumise à l'élévation d'une correction en fonction de la mesure de l'impédance interne, puis l'état de charge de la batterie est déterminé en fonction de la valeur corrigée de la tension de la batterie dans un état stable.
(JA)  開回路電圧の測定値に基づいて蓄電池の充電状態を検知する蓄電池充電状態検知方法において、蓄電池の劣化状態の如何にかかわらずに精度良く蓄電池の充電状態を検知する。  蓄電池の内部インピーダンスを測定し、前記蓄電池の安定時電池電圧を測定し、前記内部インピーダンスの測定値の大きさに応じて前記安定時電池電圧の測定値を嵩上げ補正し、前記安定時電池電圧の補正値に基づいて前記蓄電池の充電状態を求めることを特徴とする。
