Abstract: L'invention consiste essentiellement en une nouvelle méthode de diagnostic de batteries de type plomb-acide et avantageusement d'estimation de leurs durées de vie restantes, plus particulièrement destinées à des applications de stockage de secours.
La méthode est basée sur une combinaison de mesures de surveillance continue avec intégration du courant de surcharge (calcul des Ah de surcharge appliqués à la batterie dès son installation) et de mesures périodiques sous courant continu de la résistance interne de la batterie en utilisant de courtes périodes de décharge avec un courant constant ou une puissance constante.-

Abstract: Provided are a lead-acid battery system and a lead-acid battery life estimation method capable of accurately estimating a remaining life of a lead-acid battery by calculating a capacity turnover value during operation (CT value during operation) in consideration of at least one of a lower limit state of charge (SOC) or a low SOC dwell time. A capacity turnover value calculation unit (138), (237), (337), or (440) of the lead-acid battery system (S) calculates the CT value during operation by using at least one of a lower-limit-SOC-based correction coefficient K LSOC calculated based on a lower limit SOC which is an SOC having the smallest value when the lead-acid battery (B) is charged and discharged once, respectively, or a low-SOC-dwell-time-based correction coefficient K t_LSOC calculated based on a low SOC dwell time t LSOC which is an elapsed time until the next discharge or charge starts when a discharge ends below a reference SOC.

Abstract: Provided are a lead-acid battery system and a lead-acid battery life estimation method capable of accurately estimating a remaining life of a lead-acid battery by calculating a capacity turnover value during operation (CT value during operation) in consideration of at least one of an upper limit state of charge (SOC) or an upper limit voltage. A capacity turnover value calculation unit (138), (237), or (337) of the lead-acid battery system (S) calculates the CT value during operation by using at least one of an upper-limit-SOC-based correction coefficient K HSOC calculated based on the upper limit SOC which is an SOC having the largest value when the lead-acid battery (B) is charged, and an upper-limit-voltage-based correction coefficient K HV calculated based on the upper limit voltage which is the highest voltage when the lead-acid battery (B) is charged.

Abstract: Provided are a lead-acid battery system and a lead-acid battery life estimation method capable of accurately estimating a remaining life of a lead-acid battery by calculating a capacity turnover value during operation in consideration of the number of equalization charges of the lead-acid battery or an overcharge rate integrated value of the equalization charge of the lead-acid battery. The lead-acid battery system (S) estimates the remaining life of the lead-acid battery (B) by comparing a capacity turnover value from the beginning to the end of life with the capacity turnover value during operation. A capacity turnover value calculation unit (137) or (237) in the lead-acid battery system (S) calculates the capacity turnover value during operation by using an equalization-charge-number-based correction coefficient K CN calculated based on the number of equalization charges (E) or a charge-rate-based correction coefficient K CP calculated based on the overcharge rate integrated value of the equalization charge (E).
