1. A battery-pack-based battery swapping station comprising:
an external power grid configured to supply power;
at least one charger configured to charge a battery pack;
a controller configured to perform control such that the power supplied from the external power grid is transmitted to the battery pack via a system and the battery pack is charged with the power;
an alternating current/direct current (AC/DC) converter connected to the external power grid, the AC/DC converter being configured to convert current; and
a main power source configured to supply the power to the at least one charger and the controller,
wherein the controller determines an operation state of the system and, when supply of power from the external power grid is impossible, performs control such that the power stored in the battery pack is supplied to the main power source,
wherein the at least one charger comprises at least one bidirectional direct current/direct current (DC/DC) converter disposed in a housing, the at least one bidirectional DC/DC converter being configured to supply direct-current power to the battery pack, and
wherein the controller comprises:
a main control unit (MCU) formed between the AC/DC converter and the at least one bidirectional DC/DC converter, the MCU being configured to generate a control signal; and
a controller power source for driving.
