Abstract
Apparatus and associated methods relate to a system or method of precision battery charge measurement. Some embodiments may include precise charge and discharge control based on precision battery voltage and current sensing. In an illustrative example, energy either going in or out of the battery may be multiplied or computed using novel circuitry. In various embodiments, energy may be computed in a precision energy small unit determined as a percentage of total battery capacity. In an illustrative example, the precision unit may be, for example, 0.0018% of the total battery capacity. In some embodiments, the energy meter value may be in digital form, so it can be stored in memory and transmitted to external users as desired using USB type C or any other method. Various embodiments may advantageously provide extended battery life, based on using the measured energy meter value to maintain the state of charge of the battery.
