Abstract

A battery management system comprising: at least one battery comprising two or more sets of cells, each set of cells comprising one or more cells; a multiplexing switch apparatus connected to each set of cells; and at least one controller configured to use the multiplexing switch apparatus to selectively discharge the sets of cells based on at least one criterion. A battery pack comprising: at least one battery comprising two or more sets of cells, each set of cells comprising one or more cells; and an integrated switching control system comprising at least one switch connected to each set of cells, wherein the integrated switching control system is configured to control the at least one switch to discharge the sets of cells sequentially or selectively based on at least one criterion. A battery management method or a battery pack control method.
