1. A universal charging device, the device comprising:
- a plurality of charging packs each of which comprises an AC terminal for inputting an alternating current (AC) power, an AC/DC converter for rectifying the AC power to a direct current (DC) power, and a DC terminal for outputting the DC power of a first power value; and
a charging module in which the plurality of charging packs are connected attachably and detachably in parallel or serial manners, the charging module comprising an AC input portion for commonly inputting the AC power to the AC terminal, a DC output portion for connecting the DC terminal in parallel or serial manners, and a charging module controller that controls an array of the plurality of charging packs,wherein the DC output portion supplies the DC power to a connector of a kiosk, a value of the DC power is dependent on a number of the plurality of charging packs or a control status of the charging module controller, and the DC power is supplied to the connector without being battery charged, andwherein the plurality of charging packs or the charging module are separately provided from the kiosk and installed at a position different from a position of the kioskwherein;
the charging module is disposed in a charging unit, the charging unit comprising an AC bus bar commonly connected to the AC input portion or a DC bus bar connected in parallel or serial manners to the DC output portion, and a plurality of charging modules including the charging module are connected attachably and detachably in parallel or serial manners; and
the DC bus bar outputs DC power that has a value that is variable in proportion to a number of the plurality of charging modules disposed in the charging unit.
