The present invention relates to a replacement, management, and power transmission method using a battery pack replacing system of an electric vehicle serving as an energy storage system. The battery pack management method in the battery pack replacing system of an electric vehicle serving as an energy storage system comprises the steps of: separating a discharged battery pack from the electric vehicle; transferring the separated discharged battery pack to a charging and discharging line; charging and storing the discharged battery pack; primarily checking the buffer capacity of the battery pack; classifying the battery pack into a buffer battery pack for replacing a battery if the buffer capacity of the battery pack is higher than a first buffer capacity reference; moving the battery pack to a line only for storing energy if the buffer capacity of the battery pack is lower than the first buffer capacity reference; secondarily checking the buffer capacity of the battery pack; and classifying the battery pack into a battery pack only for an energy storage system. The present invention charges and stores a plurality of battery packs and the stored and charged battery pack is substituted for a discharged battery pack to be mounted on a vehicle, so accidents occurring during direct charge are reduced and time for replacement is far shorter than time for direct charge, thereby saving time as a traditional method of a driver directly charging a battery pack is switched into the battery pack replacing method. |
