Abstract: Embodiments of encapsulated battery packs, control circuitry, and their methods of manufacture are described. In one such embodiment, a battery pack includes a plurality of electrochemical pouch cells and an elastomeric encapsulant that forms at least one external surface of the battery pack. In another embodiment, a battery pack includes a plurality of electrochemical pouch cells with a portion of an encapsulant disposed between the electrochemical pouch cells and the outer housing. In yet another embodiment, a method of controlling an operation of a system includes using a current threshold of one or more electrochemical cells determined at least in part on at least one of a temperature and a state of charge of the one or more electrochemical cells.

Abstract: A cell assembly group is provided, comprising: a plurality of cell assemblies, each cell assembly including an electrochemical cell and an outer wrap surrounding the cell; a foam sheet positioned adjacent one side of one cell assembly; a plurality of heat plates, each heat plate being positioned between two cell assemblies; and at least one spacer positioned between one heat plate and one cell assembly. Each outer wrap of each cell assembly of the plurality of cell assemblies includes a body having an inner surface that engages a rearward wall of the electrochemical cell of the cell assembly, a first portion having a flame barrier that engages a forward wall of the electrochemical cell of the cell assembly, and a second portion that engages an outer surface of the first portion.
