System and method of determining power values of an information handling system that includes one or more batteries

A method, comprising:

• receiving, by an embedded controller of an information handling system, a first plurality of analog signals from a battery charger of the information handling system, wherein the first plurality of analog signals are proportional to current of a battery of the information handling system;
• receiving, by the embedded controller, a second plurality of analog signals from the battery charger, wherein the second plurality of analog signals are proportional to current from a power supply;
• receiving, by the embedded controller, a third plurality of analog signals from the battery charger, wherein the third plurality of analog signals are proportional to power consumption of a plurality of components of the information handling system and the battery;
• converting, by the embedded controller, the first plurality of analog signals to a first plurality of digital values;
• converting, by the embedded controller, the second plurality of analog signals to a second plurality of digital values;
• converting, by the embedded controller, the third plurality of analog signals to a third plurality of digital values;
• storing, by the embedded controller, the first plurality of digital values, the second plurality of digital values, and the third plurality of digital values via a memory medium;
• and
• retrieving, by the embedded controller, the first plurality of digital values, the second plurality of digital values, and the third plurality of digital values from the memory medium;
• determining, by the embedded controller, a first mean digital value from the first plurality of digital values, a second mean value from the second plurality of digital values, and a third mean digital value from the third plurality of digital values;
• and
• providing, by the embedded controller, the first mean digital value, the second mean digital value, and the third mean digital value to at least one of information handling system firmware of the information handling system, an application of the information handling system, and an operating system of the information handling system.

An embedded controller, comprising:

• at least one processor;
• and
• a memory medium, coupled to the at least one processor, that stores instructions executable by the at least one processor, which when executed by the at least one processor, cause the embedded controller system to:
• receive a first plurality of analog signals from a battery charger of an information handling system, wherein the first plurality of analog signals are proportional to current of a battery of the information handling system;
• receive a second plurality of analog signals from the battery charger, wherein the second plurality of analog signals are proportional to current from a power supply;
• receive a third plurality of analog signals from the battery charger, wherein the third plurality of analog signals are proportional to power consumption of a plurality of components of the information handling system and the battery;
• convert the first plurality of analog signals to a first plurality of digital values;
• convert the second plurality of analog signals to a second plurality of digital values;
• convert the third plurality of analog signals to a third plurality of digital values;
• store the first plurality of digital values, the second plurality of digital values, and the third plurality of digital values via a memory medium;
• and
• retrieve the first plurality of digital values, the second plurality of digital values, and the third plurality of digital values from the memory medium;
• determine a first mean digital value from the first plurality of digital values, a second mean value from the second plurality of digital values, and a third mean digital value from the third plurality of digital values;
• and
• provide the first mean digital value, the second mean digital value, and the third mean digital value to at least one of information handling system firmware of the information handling system, an application of the information handling system, and an operating system of the information handling system.
