Problems solved by technology

[0004] Excessive charging voltage and charging current will cause potential safety hazards. For example, when the current at the charging interface exceeds 5A, the current will easily break through the air and generate an arc during the process of pulling out the charging interface.

Abstract

The disclosure provides a charging terminal, method and device, which belong to the field of electronic equipment. The method includes, when the charging terminal is in the charging state, determining through the detection circuit that the connection state of the first pin on the charging interface of the charging terminal changes from the connected state to the suspended state; generating a state corresponding to the suspended state of the first pin Information; switch the charging power of the charging terminal from the first charging power to the second charging power according to the state information. The method determines whether the charging terminal is in the interrupted charging state through the change of the connection state of the first pin, and when it is determined that the charging terminal is in the interrupted charging state, reduces the charging power of the charging terminal so that the charging interface of the charging line can be pulled out safely, Avoid potential safety hazards caused by excessive charging voltage and charging current during high-power charging.

Description

technical field [0001] The present disclosure relates to the field of electronic equipment, and in particular, to a charging terminal, method and device. Background technique [0002] Currently, users have higher and higher requirements for fast charging of mobile terminals, and higher and higher charging speeds of mobile terminals have become a development trend in the future. [0003] The principle of fast charging of mobile terminals is to use high-power charging. The greater the power, the faster the charging speed; and as the charging power increases, the charging voltage and charging current will also increase. [0004] Excessive charging voltage and charging current will cause safety hazards. For example, when the current at the charging interface exceeds 5A, the current will easily break through the air and generate arcs during the process of pulling out the charging interface. SUMMARY OF THE INVENTION [0005] Embodiments of the present disclosure provide a charg...
