Abstract

The invention discloses a charging method and electronic equipment. The charging method includes the steps that the voltage of a battery of the electronic equipment is monitored in real time; when the voltage of the battery is within a low voltage range and the electronic equipment needs to be charged, the battery is charged according to a first charging rule, wherein the first charging rule comprises at least two charging stages. According to the technical scheme, the technical problem that according to electronic equipment in the prior art, neither the service life of a battery nor the energy density of a battery core can be guaranteed is solved, and the charging speed of the initial stage is increased.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a charging method and electronic equipment. Background technique [0002] With the continuous development of science and technology, various electronic devices, such as smart phones, tablet computers and notebook computers, can be continuously updated with more and more functions. [0003] At present, as the function of electronic equipment becomes more and more powerful, the capacity requirement for the battery of the electronic equipment is also higher and higher, and as the battery capacity increases, the charging time is also longer and longer. In the prior art, the The charging method is to carry out constant current charging first, and then carry out constant voltage charging when the battery voltage reaches the preset value. For this charging method, the charging speed is relatively slow, especially the initial charging speed; then in order to increase the charging spe...
