Abstract

The invention relates to the technical field of charging, and provides a mobile terminal and a charging device. The charging device comprises a charging interface, a charging switch, a power management chip and at least two charging chips, wherein a voltage outputting end of the charging switch is connected with a voltage inputting end of each charging chip; a voltage outputting end of each charging chip is connected with a battery; an outputting end of the power management chip is connected with a control end of the charging switch; and the power management chip controls connection or disconnection between the voltage inputting end and the voltage outputting end of the charging switch through the control end of the charging switch. During quick charging of the mobile terminal, outputted large current is averagely distributed on the charging chips, so that each charging chip cannot dissipate a large amount of heat, and the problem that the temperature of the mobile terminal rises during quick charging of the mobile terminal is solved.

Description

technical field [0001] The invention relates to the technical field of charging, in particular to a mobile terminal and a charging device. Background technique [0002] As the entertainment and playability of smart terminals are getting higher and higher, the problem of high power consumption of mobile phones is becoming more and more serious. Therefore, the above problems are solved by fast charging, that is, high voltage or high current is usually used to realize the charging of smart terminals. Fast charging, whether it is a high-voltage method or a high-current method, in the process of fast charging, due to the limitation of the efficiency of the charging chip, the charging chip will generate a lot of heat. The use of high current charging during fast charging causes the temperature of the charging chip to rise. Contents of the invention [0003] The purpose of the present invention is to provide a mobile terminal and a charging device, aiming to solve the problem in...
