Energy storage system

A method of assembling an energy storage system, the method comprising:

• positioning a plurality of battery cells inside a module housing, wherein each of the plurality of battery cells includes a first end and a second end, each of the plurality of battery cells further includes a positive terminal and a negative terminal;
• coupling the positive terminal of the plurality of battery cells to a first interconnect through a plurality of first cell connectors;
• coupling the negative terminal of the plurality of battery cells to a second interconnect through a plurality of second cell connectors;
• and
• positioning a top plate over the first interconnect and the second interconnect, wherein the top plate includes one or more weak areas positioned above the one or more battery cell.

An energy storage system comprising:

• a module housing;
• a plurality of battery cells positioned inside the module housing, each of the plurality of battery cells including a first end and a second end, each of the plurality of battery cells further including a positive terminal and a negative terminal;
• material for insulating the plurality of battery cells;
• material for directing a discharge from a failure of one or more battery cells;
• a plurality of first cell connectors coupled to the positive terminal of the battery cells;
• a plurality of second cell connectors coupled to the negative terminal of the battery cells;
• an interconnect layer positioned over the plurality of battery cells, the interconnect layer including:
• a first interconnect configured to couple the plurality of first cell connectors to the first interconnect;
• and
• a second interconnect configured to couple the plurality of second cell connectors to the second interconnect;
• wherein the first interconnect and the second interconnect lie in a same horizontal plane above the plurality of battery cells;
• and
• a top plate positioned over the interconnect layer, wherein the top plate includes one or more weaker portions above one or more battery cell.
