Abstract
The present invention provides a battery charger of mobile phone capable of charging a battery rapidly and fully, by charging the battery rapidly with pulse up to a predetermined level of the charging capacity of the battery, and then by charging with constant voltage until the battery is fully charged, and a charging method for the same; the battery charger comprising: a main control means, which controls pulse voltage charging and constant voltage charging based on the charging state of the battery; a constant voltage charging control means, which controls charging of the battery with constant voltage under control of the above main control means; a pulse charging control means, which detects charging voltage of the battery and controls charging of the battery with pulse voltage based on the detected charging voltage under control of the above main control means; and a charging means, which charges the battery by outputting pulse voltage or constant voltage after DC power has been applied under control of the above pulse charging control means or the above constant voltage charging control means.
