Equalization of the state of health of multiple serial strings of battery cells connected in parallel to a common direct current bus in an energy storage system utilized with a utility-sized renewable energy system or other system where optimum operational battery health is a requirement, and in particular is provided by a separate bi-directional DC-to-DC converter in each serial string that controls the charge and discharge of the multiple serial strings of battery cells to maximize efficiency of the stored energy and also provides galvanic isolation between the direct current bus and the multiple serial strings of battery cells.

Bi-directional optimizers for battery storage systems with galvanic isolation

An integrated multi-mode, large-scale electric power support system supplies on demand at least 2,500 kW to an electrical grid with low harmonic distortion either from co-located solar or wind renewable energy DC power sources or in combination with, or alternatively, from system stored energy DC power sources via a plurality of DC-to-AC inverters with phase-shifted outputs. The power support system can also inject on demand grid power factor correcting reactive power. An alternative high voltage power support system can supply on demand at least 50 megawatts to the grid.
