Problems solved by technology

However, the charging problem of mobile terminals needs to be further investigated. In order to improve the charging efficiency, most of the current mobile terminals adopt fast charging technology. Lifespan, no matter whether the fast charging technology is used or not, when the power is charged to 99%, the last 1% of the power to be charged will be completed by trickle charging with small current pulses. Generally, trickle charging takes about 30 minutes. Seriously prolonging the charging time, causing users to wait too long for mobile terminals to charge, which is not conducive to improving user experience

[0067] refer to figure 2 , figure 2 It is a schematic structural diagram of a mobile terminal provided by the first embodiment of the present invention.

[0068] This embodiment provides a mobile terminal 2, including: a first battery 21, a second battery 22, an interface circuit 23, an internal charging circuit 24, and a charging controller 25;

[0069] Wherein, the first battery 21 is the main battery of the mobile terminal 2 , and the power threshold of the first battery 21 is greater than the power threshold of the second battery 22 . It should be understood that the power threshold in the present invention refers to the maximum power that the battery can actually store, which is related to the output current, output voltage and power supply time of the battery. The product of the output current (mA) and the power supply time (hour H) indicates the battery power, which can be distinguished only for batteries with the same output voltage, but when the battery output vol...

Abstract

The invention discloses a mobile terminal, and a charge control device and a charge control method thereof. Design of double cells of a first cell and a second cell is adopted on the mobile terminal, and the voltage threshold of the second cell is larger than the voltage threshold of the first cell. The first cell and the second cell are charged through an interface circuit. When the first cell is charged until the electric quantity reaches a preset charging electricity quantity value (such as 99%), the first cell can be disconnected from an external power source, and the following charging process (at least including a part of trickle charging process) of the first cell is completed by the second cell in the mobile terminal. The mobile terminal, and the charge control device and the charge control method thereof solve the problem that a user of an existing mobile terminal needs to wait a long time for charging a cell, and facilitate improvement of usage experience for the user.

Description

technical field [0001] The present invention relates to the field of battery charging, and more specifically, relates to a mobile terminal, a charging control device and a charging control method thereof. Background technique [0002] Nowadays, mobile terminals are widely used in all aspects of people's lives, and people have even reached the point where they cannot leave the mobile terminals. For example, mobile phones, tablet computers, etc. have become indispensable items in people's lives. However, the charging problem of mobile terminals needs to be further investigated. In order to improve the charging efficiency, most of the current mobile terminals adopt fast charging technology. Lifespan, no matter whether the fast charging technology is used or not, when the power is charged to 99%, the last 1% of the power to be charged will be completed by trickle charging with small current pulses. Generally, trickle charging takes about 30 minutes. Seriously prolonging the cha...
