A power management system and method of operation is disclosed. The power management system may include a controller associated with each load or subsystem of a plurality of loads or subsystems to determine a lowest operational voltage based on an operating point of the associated load or subsystem. The power management system may further include a voltage link to supply a highest voltage of the lowest operational voltages.

Power management system including a variable voltage link

A system to manage energy may include a plurality of energy storage modules. Each energy storage module may include a power converter couplable to a link and a power converter controller to control operation of the power converter. Each energy storage module may also include at least one energy storage unit connected only to the power converter. The system may also include a power management controller to control power delivery from each of the plurality of energy storage modules to the link and to control power delivery to each of the plurality of energy storage modules. Each power converter may include a hardware voltage loop to generate a first signal in response to a line voltage and voltage command signal, and a hardware current loop to generate a second signal in response to the first signal, a line current and a command current signal, wherein the power converter is adjustable in response to the second signal to apply a predetermined power from the link to the at least one energy storage unit or to supply a selected power from the at least one energy storage unit to the link.
