Charge / discharge control method and charge / discharge control system for alkaline storage battery

摘要

PPROBLEM TO BE SOLVED: To provide a charging and discharging control method and a charging and discharging control system for an alkaline storage battery, which can prevent the deterioration of a battery formation material and preventing a memory effect. PSOLUTION: The charging and discharging control method for an alkaline storage battery includes: a step of performing first charge to predetermined charge termination voltage by first charge current on the alkaline storage battery and then, performing second charge by second charge current smaller than the first charge current; and/or a step of performing first discharge to predetermined discharge termination voltage by first discharge current and then, performing second discharge by second discharge current smaller than the first discharge current.
