MODULAR ENERGY STORAGE SYSTEM
First Claim
1. An energy storage system, comprising:
- one or more energy storage units;
one or more power conversion units coupleable to an external system;
a power transfer network coupled to the one or more energy storage units via a first interface and to the one or more power conversion units via a second interface, wherein the power transfer network includes one or more conductors that are coupleable to the first interface and to the second interface for transferring power between the one or more energy storage units and the one or more power conversion units, wherein the power conversion units are configured to convert an electrical parameter of power transferred to and from the energy storage units in accordance with an electrical requirement of the external system or the one or more energy storage units; and
a controller in communication with the power transfer network, wherein the controller is configured to selectively cause one or more of the conductors in the power transfer network to electrically connect one or more of the energy storage units to one or more of the power conversion units based at least in part on a power or energy supply or demand of the external system or an amount of energy stored in the one or more energy storage units.

Abstract
An energy storage system includes modular energy storage equipment that may be connected to an external system, such as a power grid. In at least one embodiment, the energy storage system includes a power transfer control system comprising a power transfer network and a processing module or controller. The power transfer network has a first interface coupleable to one or more energy storage units and a second interface coupleable to one or more power conversion units. One or more conductors in the power transfer network are selectively coupleable to the first interface and the second interface for transferring power between the energy storage units and the power conversion units based at least in part on information indicating a power or energy supply or demand of an external system or information indicating an amount of energy stored in the energy storage units. The energy storage system is scalable for different implementations.
