INTELLIGENT ENERGY STORAGE SYSTEM AND METHOD

摘要

An intelligent energy storage system comprises the following steps: forming a plurality of battery modules and forming an individual battery management system in each battery module, wherein the individual battery management system controls overcurrent, excessive charging, and excessive discharging during charging and discharging of multiple battery cells formed in each battery module by monitoring battery cell status information which includes voltage, current, and temperature; allowing a central control device, which manages a plurality of individual battery management systems, to receive the status information of each battery cell in each battery module from each individual battery management system; and allowing the central control device to select one power source among a plurality of power sources and to store power received from the selected power source in each battery cell of an individual battery module which is selected on the basis of the amount of energy remaining in each individual battery module by analyzing the status information of each battery cell.
