1. A scalable energy storage system, comprising:
a power rack comprising:
at least one power bank comprising:
a power bank management unit; and
a plurality of energy cells interconnected by external energy rails, wherein each one of the plurality of energy cells comprises a first cell control unit, the first cell control unit comprising:
at least one energy storage element;
a control power rail;
a control circuit having an input coupled to the at least one energy storage element by an internal energy rail, an output coupled to a cell energy rail, and coupled to the control power rail;
a plurality of energy rail switches coupled to the control circuit through the cell energy rail;
wherein the control circuit is configured to:
 independently control and manage the at least one energy storage element:
 control the plurality of energy rail switches to couple the cell energy rail to the external energy rails in a predetermined configurable dynamic wiring topology to implement a dynamic wiring system; and
 communicate with a second cell control unit using a cell communication protocol.
