SYSTEM AND METHOD FOR CHARGING CONTROL BETWEEN BATTERY PACKS

The present invention relates to a serial battery pack-to-pack charging control system and a method thereof, and to a series battery pack-to-pack charging control system configured such that a battery pack having a higher voltage can charge a battery pack having a lower voltage so as to reduce the voltage difference between the two battery packs when a voltage difference between two battery packs is large in a state where battery packs are stored in a system by being connected thereto.
