Abstract
Disclosed is a battery-charging method and apparatus which is designed to improve charging efficiency during charging of a battery using an external power source, without increasing the number of components. The battery-charging method of the present invention comprises the steps of: forming an electric circuit which includes: an alternating-current generator operable to output alternating current, and an external power source; a diode rectifier operable to rectify the alternating current output from the alternating-current generator into a direct current by a diode; and a battery which is chargeable using an output of the alternating-current generator, which are serially connected in this order; and supplying an alternating current fed from the external power source, between the alternating-current generator and the diode rectifier (S4, S1, S5).
