The present invention relates to a charging apparatus using an energy storage system (ESS) apparatus. In accordance with one embodiment of the present invention, the charging apparatus using an ESS apparatus includes: an ESS apparatus storing electric energy; and a DC-DC converter having a primary module connected in parallel with the ESS apparatus, and having a secondary module connected in series between the ESS apparatus and a target battery. At this time, in the DC-DC converter, one end of the primary module and one end of the secondary module are connected with each other, and both ends of the primary module are connected in parallel with the ESS apparatus, and the other end of the secondary module can be connected in series with the target battery. Therefore, the present invention is capable of minimizing a conversion loss during an energy conversion procedure.
