A high efficiency charging apparatus, includes a power supply which is a source for supplying electricity for charging; a speed setting unit setting an oscillating frequency and outputting an electrical self-oscillating signal having a frequency corresponding to the oscillating frequency; a switching unit having a plurality of switches which are driven by the electrical self-oscillating signal supplied from the speed setting unit; and a power transmitting unit supplying a current from the power supply to a capacitor multiple times according to a drive state of the plurality of switches of the switching unit and discharging the current charged in the capacitor at one time to supply the discharged current to the battery. The charging apparatus improves charging efficiency and reduces a charging time of a lead or nickel battery used in a vehicle or the like.
