a charger disposed in the housing; a controller configured to control the charger; a battery pack swapping power source configured to supply power to the charger and/or the controller; a power connector configured to allow the charger to be connected to a battery pack; and a plurality of battery packs, wherein the controller comprises: a controller power source for driving; a processor configured to generate a control signal; and a communication connector configured to communicate with the charger and/or the battery pack, when a supply of power from an external alternating current power source to the battery pack swapping power source is interrupted, whereby no power is supplied to the controller power source, the processor turns on a control switch to discharge power from the battery pack to the controller power source, and wherein the plurality of battery packs include at least one battery configured only for power storage and configured to charge the controller power source when power is not supplied from the battery pack swapping power source to the controller power source. ### Claim 2 (depends on 1) The battery swapping station according to claim 1, wherein the control switch is an external manipulation switch configured to be physically manipulated at an outside. ### Claim 3 (depends on 1) The battery swapping station according to claim 1, wherein the control switch is a timer switch configured to sense that no power is supplied to the controller power source independent of the processor and to discharge the battery pack after a predetermined time. ### Claim 4 (depends on 1) The battery swapping station according to claim 1, wherein the charger comprises at least one bidirectional direct current to direct current (DC/DC) converter disposed in the housing, the bidirectional DC/DC converter being configured to supply direct current power to the battery pack. ### Claim 5 (depends on 4) The battery swapping station according to claim 4, comprising an alternating current to direct current (AC/DC) converter connected to the external alternating current power source, the AC/DC converter being configured to convert current. ### Claim 6 (depends on 5) The battery swapping station according to claim 5, wherein the controller is positioned between the AC/DC converter and the bidirectional DC/DC converter. ### Claim 7 (depends on 6) The battery swapping station according to claim 6, comprising a DC/DC converter positioned between the AC/DC converter, the bidirectional DC/DC converter, and the controller. ### Claim 8 (depends on 3) The battery swapping station according to claim 3, wherein the timer switch comprises a self-power source. ### Claim 9 (depends on 1) The battery swapping station according to claim 1, wherein the controller further comprises a voltage sensing unit configured to determine whether voltage from the battery pack swapping power source and the controller power source is abnormal. ### Claim 10 (depends on 1) An electrically driven device comprising: a receiving unit configured to receive identification information of the battery swapping station having the emergency power generation function according to claim 1; and a central processing unit (CPU) configured to determine whether to communicate with the battery swapping station based on the identification information received from the battery swapping station and authentication information. ### Claim 11 (depends on 10) A system comprising: the electrically driven device of claim 10; and the battery swapping station, wherein the electrically driven device and the battery swapping station communicate through a short-range communication, and wherein the battery swapping station transmits the identification information via a short-range communication channel.
