Abstract

The invention discloses a charging method and an electronic device. The charging method is applied to an electronic device which includes an electric storage unit. The method includes: at a first moment, when a charging device which is connected with the electronic device charges the electric storage unit, a first voltage value at the two ends of the electric storage unit is obtained through detection; based on the first voltage value, a first parameter value related with a charging current of the electric storage unit is determined; whether the first parameter value satisfies a preset condition is judged; when the first parameter value satisfies the preset condition, the value of the charging current is adjusted form a first current value to a second current value so that a second power value which is obtained on the basis of the second current value and a second voltage value of the electric storage unit corresponding to the second current value is equal to a preset power threshold.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a charging method and electronic equipment. Background technique [0002] With the development of global information technology, electronic equipment products have completely penetrated people's lives. Many electronic equipment products, such as notebooks, mobile phones, PADs, etc., have become widely popular tools due to their portable characteristics, bringing more and more convenience to users. [0003] Among them, these electronic devices all need a power supply to supply power. In the prior art, a constant current and constant voltage charging mode is usually used for charging. In the initialization phase, the power supply unit is charged in a constant current mode. At this stage, the power of the power supply unit increases linearly with time, and its voltage value also increases until its voltage value reaches the preset voltage upper limit; Perform constant voltage...
