Abstract
The life of a lead acid storage battery is extended by changing an over-frequency equalized charge interval performed on a lead acid storage battery, in accordance with a transition situation of a state of charge (SOC) of the lead acid storage battery. The lead acid storage battery is also made to be advantageous in terms of cost by reducing the equalized charge with a low degree of urgency to reduce the power and cost for equalized charge, and by reducing the number of stops of a natural energy storage system. A lead acid storage battery and a lead acid storage battery system whose operational management can be easily performed are achieved by a method in which the future timing when the equalized charge is performed can be grasped by people operating the lead acid storage battery.
