Abstract

An electrochemical battery system in one embodiment includes a first electrochemical cell, a memory in which command instructions are stored, and a processor configured to execute the command instructions during a discharge cycle of the first electrochemical cell to (i) establish a first discharge voltage of the first electrochemical cell based upon a first sensed discharge voltage, and (ii) permit a second discharge voltage of the first electrochemical cell after establishing the first discharge voltage, wherein the second discharge voltage is greater than the first discharge voltage.
