Distributed architecture for uni-directional and bi-directional power transfer in an electrical storage system

摘要

An energy distribution system and methods for coupling a plurality of energy storage cells to at least one of an energy source and an energy load. Each energy storage cell is coupled, at an interface, via a distinct power converter, to a winding, as is an energy source or load, coupled at an energy port to a secondary winding. The plurality of windings sharing a magnetic flux field and thus constitute a transformer. While separate processors are associated with each power converter, a subset of the plurality of processors may be intercoupled for control based on conditions associated with at least one of the plurality of energy storage cells. A central processor may govern operation of a subset of the processors, moreover, a subset of the plurality of processors may also be connected to a local area network and the central processor may communicate with other processors and may also be coupled to an external network such as the internet. Cells are readily switched out individually and recruited to match instantaneous load demand.
