Abstract

The invention provides a charging method, which comprises the steps that a mobile terminal is provided, wherein the mobile terminal comprises a first circuit board, a first charging chip arranged on the first circuit board, a second circuit board, a second charging chip arranged on the second circuit board and a battery; the second charging chip is connected to the first charging chip in parallel; the battery is connected to the first charging chip and the second charging chip; the mobile terminal is connected to a charging power supply for charging the battery and simultaneously adjusting the charging state according to voltage of the battery; when the voltage of the battery is lower than second critical voltage, the battery enters a pre-charging state; when the voltage of the battery is greater than or equal to second critical voltage and smaller than third critical voltage, the battery enters a fast charging state; when the voltage of the battery is greater than or equal to the third critical voltage, the battery enters a constant-voltage charging state; and when charging current is smaller than or equal to cutoff current, charging is ended. By the charging method, the charging efficiency can be improved.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a charging method. Background technique [0002] As the battery capacity of the mobile terminal increases, the charging time of the battery becomes longer and longer. In the prior art, dual charging chips are used to quickly charge the battery, which can effectively shorten the charging time of the battery. [0003] The charging chip is generally arranged on the main board of the mobile terminal. During the charging process, the temperature of the charging chip will rise, resulting in a relatively large temperature rise of the main board. For the charging scheme with dual charging chips, the temperature rise of the main board is even greater. [0004] At present, the mainstream heat dissipation method is to use water-cooled heat-conducting copper tube technology to conduct heat to other places through copper tubes for heat dissipation, but the cost is relatively high, and the ...
