Abstract:
An apparatus and a method for charging a battery using a solar cell are provided. The apparatus for charging a battery using a solar cell comprises: a voltage measuring unit measuring an output voltage of the solar cell; a charge current control signal generating unit generating a charge current control signal increasing following a predetermined charge current control curve increasing with a constant slope over time while the measured output voltage of the solar cell is greater than or equal to a predetermined minimum voltage; a switching signal generating unit generating a pulse width modulation signal by comparing the generated charge current control signal with a carrier signal; and a DC/DC converter controlling a charge current for the battery according to the generated pulse width modulation signal. Therefore, it is possible to reduce time required for complicated operations and charge the battery with the maximum current in spite of variation of sunshine.
