Charging method and user equipment

A user equipment, comprising:

• a measuring module, configured to measure a maximum output current value of a charger according to a received fast charging instruction;
• a charging current setting module, configured to determine a charging current value for a battery of the user equipment according to the maximum output current value;
• a charging current receiving module, configured to receive, from the charger, an initial first charging current corresponding to the charging current value;
• and
• a charging temperature control module, configured to disconnect the charger if a charging temperature of the battery is detected to be higher than a preset temperature,
• wherein the measuring module comprises:
• an actual output current value measuring unit, configured to measure an actual output current value of the charger corresponding to a preset charging current value according to the received fast charging instruction;
• and
• a maximum output current value measuring unit, configured to compare the actual output current value of the charger with the preset charging current value, and if the actual output current value of the charger is greater than the preset charging current value, increase the preset charging current value and repeat the above step, and after the measured actual output current value of the charger corresponding to the increased preset charging current value is smaller than the increased preset charging current value, determine that the measured actual output current value of the charger corresponding to the increased preset charging current value is the maximum output current value of the charger.
