1. A method for adapting a usage level of a battery pack having a plurality of battery cells, the method comprising:
measuring cell sense data for each respective one of the battery cells using a cell sense circuit, the cell sense data including a cell voltage, a cell current, and a cell temperature;
processing the cell sense data, for each respective battery cell of the plurality of battery cells, through multiple battery state functions of a controller to thereby generate a plurality of numeric cell degradation values (CDVs), wherein the multiple battery state functions are calibrated relationships of the cell sense data to predetermined battery fault conditions;
automatically adapting the usage level of the battery pack during operation of the battery pack, via the controller, based on the numeric CDVs; and
wherein automatically adapting the usage level of the battery pack during operation of the battery pack includes controlling operation of an offboard charging station and/or an onboard solar panel during a charging operation of the battery pack.
