  • Patent number: 9488977
    Abstract: A power storage system includes n number of slave BMSs for transmitting data associated with an electric characteristic value of battery cells, included in battery modules managed by the slave BMSs, through slave communication networks; m number of master BMSs for primarily processing the data associated with an electric characteristic value of battery cells, transmitted through the slave communication networks, and transmitting the primarily processed data through a master communication network; and a super master BMS for secondarily processing the data transmitted through the master communication network. Since the data transmitted from each slave BMS are processed in a master BMSs, the amount of data loaded on a communication line may decrease.
