Battery charger of mobile phone using constant voltage and pulse, and high speed charge method for the same
First Claim
1. A battery charger of a mobile phone comprising:
- a main control means, which controls pulse voltage charging and constant voltage charging of a battery based on the charging state of said battery;
a constant voltage charging control means, which controls charging of said battery with constant voltage under control of said main control means;
a pulse charging control means, which detects charging voltage of said battery and controls charging of said battery with pulse voltage based on said detected charging voltage under control of said main control means; and
a charging means, which charges said battery by outputting pulse voltage or constant voltage after DC power has been applied under control of said pulse charging control means or said constant voltage charging control means.
