Bidirectional power converter for balancing state of charge among series connected electrical energy storage units
TL;DR: In this article, a system for balancing state of charge among series connected electrical energy storage units that includes a power converter that selectively couples to an individual storage unit of the a string of connected EH storage units and transfers energy by bidirectionally between the individual unit and the string of storage units is described.
Patent
System and method for determining and balancing state of charge among series connected electrical energy storage units
TL;DR: In this article, a system and method for determining and balancing state of charge among series of connected electrical energy storage units is provided, where the state of change of a selected storage unit in a string of storage units are determined by applying a non-dissipative load to the selected storage units, resulting in an energy transfer between the selected unit and the string of electrical energy units through the non-dispative load and determining the state-of-charge of the selected device from voltage and current data of the stored unit resulting from the energy transfer.
Patent
System and method for balancing state of charge among series-connected electrical energy storage units
TL;DR: In this article, a system and method of balancing state of charge among a number of connected electrical energy storage unit is provided, where individual storage units are selectively coupled by semiconductor switches for monitoring and balancing state-of-charge.
Patent
Cell balancing system for equalizing state of charge among series-connected electrical energy storage units
TL;DR: In this article, a system and method of balancing state of charge among plural series connected storage unit is provided, where individual storage units (105) are selectively coupled by semiconductor switches (300) for monitoring and balancing state-of-charge.
