Energy storage system including submodules having structural interconnect boards

A modular energy storage system comprising:

• at least two energy storage enclosures coupled to one another;
• a power conversion module coupled to an external power source and the at least two energy storage enclosures, wherein each of the at least two energy storage enclosures includes:
• a battery pack;
• a plurality of battery modules disposed within the battery pack;
• a plurality of battery submodules disposed within each of the plurality of battery modules;
• a plurality of battery cells disposed within each of the plurality of battery submodules, wherein each of the plurality of battery cells includes structural interconnect board (ICB) assemblies disposed on opposing sides of each of the plurality battery cells,
• wherein each of the structural ICB assemblies includes a carrier having:
• a main portion that extends along one of the opposing sides of the battery cell;
• a first end portion that extends perpendicularly from a first end of the main portion along a top surface of the battery cell;
• and
• a second end portion that extends perpendicularly from a second end of the main portion along a bottom end of the battery cell.

A battery module for an energy storage enclosure, the battery module comprising:

• a plurality of battery submodules arranged within the battery module;
• and
