Uninterrupted power system for mobile phone and power supply method thereof

Abstract

The invention relates to a mobile phone uninterruptible power supply system and a power supply method thereof. The mobile phone uninterruptible power supply system comprises a submachine battery and a mother block battery; a power supply switching circuit and a charging switching circuit are connected with the submachine battery and the mother block battery; the power supply is switched between the submachine battery and the mother block battery through the power supply switching circuit; and the charging is switched between the submachine battery and the mother block battery through the charging switching circuit. The mobile phone uninterruptible power supply system and the power supply method thereof can enable a user to automatically switch the batteries under the situation that the normal work of a mobile phone is not affected when the power of the battery is lower and can not be used or the battery has sudden power failure, thereby avoiding the phenomena of shutdown, disconnection, and the like under the situation that the battery voltage of the mobile phone is insufficient, realizing the uninterruptible power supply, and prolonging the working time of the mobile phone.
