    摘要: An apparatus for controlling a battery pack and an energy storage system including the apparatus are disclosed. In one embodiment, the battery pack includes at least one battery tray each including one or more battery cells. The apparatus may include an open circuit voltage (OCV) calculator and a state of charge (SOC) estimator. The OCV calculator may receive OCV measurement values of the battery cells of each battery tray when the power of the battery pack is turned on, and calculate a final OCV of the battery cells based at least in part on the OCV measurement values. The SOC estimator may extract an SOC value corresponding to the final OCV from an SOC table and estimate the extracted SOC value as an initial SOC.

    摘要: A battery system having components with reduced maximum voltage tolerance requirements is disclosed. The battery system includes a battery pack with battery modules, and measuring units, which are connected to the battery modules. The measuring units have first analog front ends (AFEs) for monitoring the at least two battery modules. Each first AFE is configured to transmit information related to the monitored characteristic via an isolator to a processor configured to control the battery pack based on the transmitted information. The isolator receives the transmitted information from an AFE which is not connected to the battery module having the least electric potential or to the battery module having the greatest electric potential.

    摘要: A method of charging a secondary battery and a charging device that can improve stability and extend the life span of the battery. When the secondary battery includes a plurality of cells, the charging method is changed when a voltage imbalance from 100 mV to 300 mV occurs among the cells. In that range, the charging method changes from a constant current-constant voltage charging method to a pulse-charging method. When the voltage imbalance is 300 mV or more, the electricity path is blocked, shutting down the battery. When the voltage imbalance is 100 mV or less, the constant current-constant voltage charging method is maintained. The method and device also stop charging when the battery reaches full charge.
