Abstract

The invention discloses a charging method. The charging method comprises the following steps: charging a battery by adopting constant charging current; when the cell voltage achieves the first voltage threshold, charging the battery by adopting staged constant charging voltage, wherein the charging voltages at various stages are in descending order; when the charging voltage is equal to the full charge voltage of the battery, stopping charging. Furthermore, the invention further discloses a charging device capable of implementing above mentioned method, and a mobile terminal comprising above charging device. The efficient charging of the battery can be realized according to the technical scheme disclosed by the invention.

Description

technical field [0001] The invention relates to the technical field of battery charging, in particular to a charging method, device and mobile terminal. Background technique [0002] With the development of mobile Internet technology, mobile terminal devices such as smartphones, tablet computers, and wearable devices are becoming more and more popular. [0003] Current mobile terminals are mainly powered by rechargeable batteries, such as lithium batteries. The existing battery charging scheme is constant current-constant voltage charging, that is, charging with a constant current at the initial stage. When the battery voltage is detected to reach a given voltage, the charging will continue at a constant voltage, and the charging will end when the charging current drops to a given value. . Constant current charging can speed up the charging speed and shorten the charging time; when a given voltage is reached, constant voltage charging can avoid battery overcharging. Howev...
