APPARATUS AND METHOD FOR CONTROLLING POWER OF PARALLEL MULTIPACK SYSTEM

Disclosed is an apparatus and method for controlling power of a parallel multi pack system. The power control apparatus includes first to n sensor units for measuring operation characteristic values of first to n battery packs connected in parallel; a power management unit for controlling a power consumed in a load or a power provided by a charging device; and a multi pack management unit, and the multi pack management unit determines a pack resistance of each of the first to n battery packs based on the operation characteristic value of each battery pack received from the first to n 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 that 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.
