Abstract
Disclosed is an apparatus and method for controlling charge and discharge of a secondary battery. The apparatus for controlling charge and discharge of the secondary battery includes the power control unit calculates an amount of discharging power of the secondary battery, and when voltage value of the secondary battery is less than a preset reference voltage value, outputs a compensation charge control signal to charge the secondary battery with an amount of charging power obtained by adding an amount of power compensation to the calculated amount of discharging power. According to the present disclosure, the problem of a charge amount of the secondary battery reducing gradually with increasing charge and discharge cycles of the secondary battery may be prevented by compensating for the charge amount of the secondary battery.
