Abstract

The invention provides a charging method and a user equipment, and the charging method comprises the following steps: measuring the maximum output current value of a charger according to a received quick charge command; setting a charging current value for a battery of the user equipment according to the maximum output current value; receiving a first charging current corresponding to the charging current value from the charger; and disconnecting from the charger if the detected charging temperature of the battery is higher than a preset temperature. By adopting the charging method and the user equipment, the problems that the charger is damaged due to overload during emergency charge in the prior art and the charge explosion of the battery of the user equipment is caused due to too high charging temperature can be solved, and the safe and quick charge can be realized.

Description

technical field [0001] Embodiments of the present invention relate to electronic technologies, and in particular, to a charging method and user equipment. Background technique [0002] At present, charging the battery of a mobile phone generally adopts a method of first charging with a constant current and then charging with a constant voltage. The main process is: first charge the battery of the mobile phone with a constant current. When the battery voltage of the mobile phone reaches the charging cut-off voltage, the actual voltage of the battery is partially falsely high due to the internal resistance of the battery. It is necessary to continuously reduce the charging current, that is, use The constant voltage continues to charge the battery of the mobile phone until the false high part is completely eliminated, thus completing the charging. [0003] In the process of realizing the present invention, the inventors found that there are at least the following problems in t...
