Abstract: Described 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 (CT) value during operation in consideration of at least one of an upper limit state of charge (SOC) or an upper limit voltage. A CT value calculation unit calculates the CT value during operation using at least one of an upper-limit-SOC-based correction coefficient (KHSOC) calculated based on the upper limit SOC, which is an SOC having the largest value when the lead-acid battery is charged, or an upper-limit-voltage-based correction coefficient (KHV) calculated based on the upper limit voltage, which is the highest voltage when the lead-acid battery is charged.

Abstract: Described 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 estimates the remaining life of the lead-acid battery by comparing a capacity turnover value from the beginning of life to the end of life with the capacity turnover value during operation. A capacity turnover value calculation unit in the lead-acid battery system calculates the capacity turnover value during operation by using an equalization-charge-number-based correction coefficient KCN calculated based on the number of equalization charges or a charge-rate-based correction coefficient KCP calculated based on the overcharge rate integrated value of the equalization charge.

Abstract: Described 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 a magnitude of a depth of discharge (DOD). The lead-acid battery system estimates the remaining life by comparing a capacity turnover value from the beginning to the end of life with the capacity turnover value during operation. The lead-acid battery system includes a capacity turnover value calculation unit that calculates the capacity turnover value during operation. The capacity turnover value calculation unit calculates the capacity turnover value during operation using a DOD-based correction coefficient calculated based on the DOD, which is calculated by dividing an integrated discharge capacity after the start of the discharge of the lead-acid battery by a rated capacity of the lead-acid battery.

A capacity turnover value calculation unit calculates the CT value using at least one of a lower-limit-SOC-based correction coefficient KLSOC calculated based on a lower limit SOC, which is an SOC having the smallest value when the lead-acid battery is charged and discharged once, respectively, or a low-SOC-dwell-time-based correction coefficient Kt_LSOC calculated based on a low SOC dwell time tLSOC, which is an elapsed time until the next discharge or charge starts when a discharge ends below a reference SOC.

Abstract: An electrolytic synthesis system is equipped with an electrolysis device, a synthesis device, a gas adsorption type storage battery, and a control device. The gas adsorption type storage battery adsorbs, to electrodes thereof, carbon dioxide gas within the atmosphere during charging, and releases the carbon dioxide gas that was adsorbed to the electrodes, during discharging. When an adsorption amount of the carbon dioxide gas adsorbed to the electrodes exceeds a predetermined first threshold value, the control device controls a discharging switch and thereby initiates discharging of the gas adsorption type storage battery.
