Abstract

The embodiment of the invention provides a mobile terminal which comprises a receiving coil which is arranged at the surface of the battery of the mobile terminal, a heat generating circuit, a charging circuit, and a central processor CPU, wherein one end of the heat generating circuit is electrically connected to the first end of the receiving coil and the other end is connected to the second end of the receiving coil, the input end of the charging circuit is connected to the first end of the receiving coil and the output end is connected to the second end of the receiving coil, the CPU is connected to the first switch in the heat generating circuit and the second switch in the charging circuit, when the CPU detects that the mobile terminal is on a wireless charging seat and the temperature of the battery is smaller than a preset value, the receiving coil generates heat energy and transfers the generated heat energy to the battery, and when the CPU detects that the mobile terminal is on the wireless charging seat and the temperature of the battery is larger than or equal to the preset value, the battery is charged. According to the embodiment of the invention, the mobile terminal is allowed to be charged in a low temperature environment.

Description

Technical field [0001] The present invention relates to the field of electronic technology, in particular to a mobile terminal. Background technique [0002] With the development of technology, the wireless charging method of mobile terminals has been welcomed by people because of its convenience. However, since most mobile terminals use lithium batteries, when the ambient temperature is too low, the fluidity of the electrolyte in the lithium battery decreases, and the movement of lithium ions is blocked. It is easy to cause lithium evolution during charging, reduce battery capacity and life, and even cause internal battery Short circuit, causing danger. Therefore, in order to prevent these hazards, mobile terminals will generally be <0℃), the charging function is disabled. [0003] Since the mobile terminal has low-temperature charging protection, the mobile terminal will run out of power under low temperature conditions but cannot be charged due to the low ambient temperatur...
