Embodiment Construction

[0028] The following description of the preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application or uses. For purposes of clarity, the same reference numbers will be used in the drawings to identify the same elements. The term module or device is used herein to refer to an Application Specific Integrated Circuit (ASIC), electronic circuit, processor (shared, dedicated, or group) executing one or more software or firmware programs that provides the described functionality and memory, combinational logic, and / or other suitable components. The term current swing as used herein refers to the current integrated over a duration during which the charge (polarity) is in one direction. Charge swing can be expressed in ampere-seconds or A-s.

[0029] An exemplary system that may be used to calculate the SOC will be shown, but those skilled in the art will recognize that other systems may be used. Referring now to FIG. 1 ,...
