Abstract
A power charging apparatus and a battery apparatus quickly charge a battery with power by separately charging each battery cell with power. The power charging apparatus includes: a power supplier supplying power; and a charging part having at least two chargers corresponding one-to-one to at least two battery cells connected to each other in parallel, each of the at least two chargers charging the corresponding battery cell with power transmitted from the power supplying unit. The battery apparatus includes: a battery having at least two battery cells connected to each other in parallel; and a charging part having at least two chargers corresponding one-to-one to the at least two battery cells and charging the at least two chargers with power received.
