Abstract

The invention discloses a charging control device. The charging control device comprises a voltage monitoring unit, a control unit and an execution unit, wherein the voltage monitoring unit and the execution unit are connected to the output end of a charger and the control unit respectively; the control unit is used for controlling the execution unit to increase or decrease the output current of the charger; the voltage monitoring unit is used for judging whether the drop value of the output voltage of the charger is greater than a preset threshold value and sending judging results to the control unit; the control unit is used for controlling the execution unit to decrease the output current of the charger when the drop value of the output voltage of the charger is greater than the preset threshold value; when the drop value of the output voltage of the charger is less than or equal to the preset threshold value, the control unit controls the execution unit to increase the output current of the charger. The invention further discloses a charging control method and a POS terminal of the charging control device. According to the charging control device provided by the invention, the charging efficiency of the charger can be effectively improved.

Description

technical field [0001] The invention relates to the field of charging electronic equipment, in particular to a charging control method and device and a POS terminal.
