System and method for power storage and distribution

A method for power distribution, the method comprising:

• receiving input power at an input power connection of an input power distribution circuit having a plurality of output power connections coupled to at least a first power supply and a first battery module of a scalable battery bank, wherein the first power supply comprises a controllable converter configured to receive a control signal from a system control circuit;
• distributing the input power to at least the first power supply and a first battery charger of the first battery module, wherein the first battery charger and the first power supply comprise substantially identical input and output power connectors, wherein the first power supply and the first battery charger are removable and interchangeable with each other, and wherein distributing the input power to the first battery charger includes providing power from an output power connection of the plurality of output power connections to a battery input of the first battery module;
• providing a first DC (direct current) voltage to a common DC bus line from the first power supply during a first mode of operation;
• providing a second DC voltage to the common DC bus line from a first battery of the first battery module during a second mode of operation at a battery output of the first battery module, the battery output being separate from the battery input;
• and
• providing output power derived from at least one of the first power supply and the first battery.

A power system comprising:

• an input power distribution circuit having an input power connection coupled to a power source to receive input power, and a plurality of output power connections;
• a plurality of power supplies each respectively coupled to a respective output power connection of the plurality of output power connections to receive the input power, and each having a respective power supply output, each power supply respectively comprising a controllable converter configured to receive a control signal from a control circuit of the power system;
• a scalable battery bank including a plurality of battery modules, each battery module including a battery and a battery charger, and each battery charger comprising substantially identical input and output power connectors with at least one of the plurality of power supplies, wherein each battery charger is interchangeable with the at least one of the plurality of power supplies, and wherein each battery module includes a respective battery input coupled to a respective output power connection of the plurality of output power connections to receive the input power, and includes a battery output separate from the battery input;
• an output power distribution circuit coupled to the battery outputs, the power supply outputs, and a plurality of loads, the output power distribution circuit being configured to deliver adjustable output power derived from at least one of the plurality of power supplies or at least one of the plurality of battery modules to each load of the plurality of loads;
• and
• an exterior enclosure positioned to encase the power system.
