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.
