A system for determining a remaining battery capacity includes a detection circuitry and a controller. The detection circuitry is coupled to a battery device at a detection node for detecting a closed circuit voltage of the battery device. The controller is coupled to the detection circuitry, derives an amount of current drawn out from the battery device based on the closed circuit voltage, calculates an open circuit voltage of the battery device based on the current, and determines the remaining battery capacity of the battery device based on the open circuit voltage.
