LEAD ACID STORAGE BATTERY AND LEAD ACID STORAGE BATTERY SYSTEM FOR A NATURAL ENERGY USING SYSTEM

摘要

And the interval of frequency equalization charging are changed according to the transition state of the state of charge (SOC) of the lead-acid battery, thereby making the lead-acid battery prolonged life. This system reduces the power and cost of uniform charging by reducing the equalization charge with low urgency, and reduces the chances of stopping the wind power and power storage system, thereby setting a superiority in terms of cost. Lead-acid batteries and lead-acid battery systems that are easy to manage by ensuring that the timing of the equally-charged charge on the side of operating the lead-acid batteries can be grasped. A lead acid battery and a lead acid battery system, comprising: a battery state measuring unit; an SOC model; an SOC estimating unit for estimating an SOC based on information measured by the battery state measuring unit and SOC model information; An SOC transition history DB for recording the estimated SOC value in the SOC transition DB to examine the transition state of the SOC, a deterioration model of the lead acid battery, an SOC transition state from the SOC transition history management unit, Based on the information of the model, it is possible to carry out the equal charge optimum planning part for planning the optimum lead acid battery implementation method, the SOC transition information and the equal charge information output part, and the equal charge Is provided in the battery pack.
