BATTERY SWAPPING STATION AND BATTERY CHARGING METHOD USING SAME

A battery swapping station and a battery charging method using the same according to embodiments of the present invention may charge at least one battery accommodated in a battery charger according to a standard charge mode, a fast charge mode, and a discharge mode, thereby rapidly charging a target battery using allocated power provided from a grid and a charged battery without any additional power reinforcement work and preventing battery lifespan degradation caused from long-term persistence of fully charged state by adjusting a drain current of a battery that has been charged using the discharge mode, and thus, provide a high-efficiency and low-cost battery swapping station and a battery charging method using the same.
