  "textContent": "Disclosed is a high efficiency charging apparatus, comprising: 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 charging current in the power supply multiple times according to a drive state of the plurality of switches of the switching unit and discharging the charged current at a time to supply the discharged current to the battery. The charging apparatus is capable of improving charging efficiency and reducing a charging time of a lead or nickel battery used in a vehicle or the like.",
