Abstract
A multi-source energy storage system (ESS) includes a master controller and a plurality of ESSs. A first ESS includes an ESS controller and a plurality of micro-ESSs. A first micro-ESS includes a plurality of nano-ESSs, a micro-ESS controller, and a pulse width modulator. A first nano-ESS includes a plurality of cells, a plurality of cell balancing converters, a bidirectional DC-DC converter and a nano-ESS controller. The multi-source ESS operates in a charging mode and a discharging mode. The multi-source ESS is connected to one of a load, an electric grid or a micro-grid, and provides power thereto when it operates in the discharging mode. The multi-source ESS receives power when it operates in the charging mode.
