1. A battery self-discharge current measurement apparatus comprising:
a first resistor connected to a battery;
a voltage generator configured to generate a second output voltage based on a first output voltage generated based on a voltage applied to the battery and the first resistor and a second output signal generated by converting the first output voltage, and apply the second output voltage to a second resistor; and
a controller configured to monitor a current applied to the second resistor.
