1. A system for charging a battery of a vehicle, the system comprising:
a power factor correction unit configured to receive a commercial AC power being applied, and configured to correct a power factor of the AC power;
a plurality of link capacitors coupled to an output terminal of the power factor correction unit;
a plurality of converters each having input terminals connected to each of the plurality of link capacitors in a one-to-one correspondence, and configured to convert voltages applied to the input terminals;
a main battery configured to be charged with powers converted by the plurality of converters;
a plurality of swappable batteries connected to the input terminals of the converters using switches; and
a controller applying the commercial AC power or voltages by the plurality of swappable batteries to the input terminals of the plurality of converters by controlling the switches of the plurality of swappable batteries depending on whether the commercial AC power is applied.
