Abstract

The present invention relates to a charging circuit realized on a mobile phone and a charging method thereof. The charging circuit comprises two dry battery connecting ends which are electrically connected, a dry battery voltage detecting end, a capacitor filter circuit, an inductor energy storing circuit, a voltage switcher, an RC circuit consisting of a capacitor and a resistor, an enabling pin, a feedback circuit consisting of a resistor and an RC filter circuit, a protecting resistor and a diode. The mobile phone charging circuit and the charging method thereof enable a user to use the dry battery for charging the mobile phone directly under the condition that the user is in the open air or can not use a charger to charge the mobile phone immediately, so as to prolong the speaking time or the stand-by time of the mobile phone.

Description

technical field [0001] The invention relates to a mobile phone charging circuit and a charging method thereof, in particular to a circuit and a method for charging a mobile phone battery by an alkaline battery. Background technique [0002] In the current mobile phone application, the mobile phone uses nickel-cadmium, nickel-metal hydride or lithium-ion batteries. When the battery power is exhausted, it needs to charge the battery. The general charging method is to charge the battery through an AC power supply and a charger. And generally often occur that the battery power of the mobile phone is low, and the phone cannot be maintained; if it cannot be charged immediately or the user can not use the charger to charge the mobile phone when going out, it will bring a lot of inconvenience to the mobile phone user. Contents of the invention [0003] The main purpose of the present invention is to provide a mobile phone charging circuit and its charging method. The mobile phone ...
