る。The amount of electricity before gas generation when charging a lead-acid battery with a discharge amount C [Ah] before charging is approximately 80% or more of the discharge amount C.
Since it is 90%, if the full charge amount is 1.05C to 1.1C, the terminal charge amount required for tapering the charging current at the end of charge is (1.05C to 1.1C)-(0.8C).
C to 0.9C), that is, 0.15C to 0.3C. Therefore, the ratio of the taper charge amount to the initial charge amount is Is. The value of the charge amount ratio can be selected to be a substantially constant value for the substance of the lead storage battery. Therefore, if the value is determined, the initial charge time t 1 and the final charge time t 2 shown in FIG.
-T 1 ratio With a timer that can set the time to match 0.144 to 0.37, taper control of the charging current is performed to automatically adjust the end of charging period depending on the size of the lead storage battery remaining capacity or the size of the lead storage battery capacity. Therefore, it is possible to ensure proper charging amount and perform proper charging without overcharging.
