Battery management control method

An apparatus comprising:

• a first circuit coupled between a first node and a second node, wherein the first circuit is configured to output a source current via the second node and a battery discharge current via the first node, wherein the first circuit is configured to combine first and second portions Icharge and Icrep, respectively, to create the source current, wherein the first circuit is configured to combine first and second portions Idischarge and Idcrep, respectively, to create the discharge current, wherein the first circuit is configured to receive Icharge from the first node, and wherein the first circuit is configured to receive Idischarge from the second node;
• a second circuit coupled to the first circuit and configured to receive Icrep and Idcrep, wherein the second circuit is configured to generate a first voltage that is related to Icrep, wherein the second circuit is configured to generate a second voltage that is related to Idcrep, and wherein the first circuit is configured to receive Icrep and Idcrep from the second circuit;
• an analog-to-digital (ADC) conversion circuit coupled to the second circuit, wherein the ADC circuit is configured to generate a first digital signal that represents the first voltage, and wherein the ADC circuit is configured to generate a second digital signal that represents the second voltage;
• wherein Icrep is equal to Icharge/N;
• wherein Idcrep is equal to Idischarge/M;
• where N and M are values greater than one.
