Abstract
A method of determining electrochemical charge acceptance limits by measuring and determining the peak of the curve of Differential Equivalent Series Resistance (DESR) of a cell or system for the purpose of monitoring or controlling processes internal to the cell/system (i.e.; state-of-charge or state-of-formation) or for monitoring or controlling processes external to the cell/system (i.e.; battery chargers or battery formers). The method is suitably embodied in software, firmware, hardware, or apparatus.
