Abstract

The invention provides a multiplexer and fast charging control method, a control device and a mobile terminal. Among them, the multiplexer and fast charging control method includes detecting the power of a battery and the temperature of a charging chip of any way among multiple ways of charging circuits when switching on power supply for charging, and controlling the states of the switching on and the outage of a relevant charging switch of a charging chip of any way according to the battery power and the temperature of the charging chip of any way detected. According to the technical scheme, the states of the switching on and the outage of the charging switch of any way can be controlled, and then the multiplexer and fast charging control method can prevent the temperature of charging chip becoming too high, increasing the charging speed as faster as possible and improving the user experience on the premise of ensuring a safe temperature.

Description

technical field [0001] The present invention relates to the technical field of charging, in particular to a multi-channel fast charging control method, a multi-channel fast charging control device, a mobile terminal and a charger. Background technique [0002] In the traditional charging scheme, the charging circuit is single, and the charging efficiency is low. As the user's demand for terminal equipment is getting higher and higher, the traditional charging method cannot meet the needs of consumers. In order to solve this problem, in the existing technical solutions, it is proposed to adopt the method of low voltage and high current, and in order to prevent the circuit from breaking down when the current is too high, and to solve the problem of excessive loss of large current in the transmission line, certain measures have been taken. Current sharing measures, such as using two charging chips for shunting; there are also technical solutions to charge the battery by increas...
