APPARATUS AND METHOD FOR CONTROLLING POWER OF PARALLEL MULTI PACK SYSTEM

Disclosed is an apparatus and method for controlling power of a parallel multi pack system. The power control apparatus includes first to nsensor units measuring operation characteristic values of first to nbattery packs connected in parallel; a power management unit controlling a power consumed in a load or a power provided by a charging device; and a multi pack management unit that: determines a pack resistance of each of the battery packs based on the operation characteristic value of each battery pack received from the sensor units, determines a minimum available power among available powers respectively corresponding to the pack resistances of the battery packs, determines a total power of the parallel multi pack system so the pack power of a battery pack having a lowest pack resistance becomes identical to the minimum available power, and transmit the determined total power to the power management unit.
