Electronic device charging control device

The utility model belongs to the technical field of charging, and provides an electronic device charging control device. When the electronic device charging control device charges a battery in an electronic device, a power supply adapter charges the battery through constant voltage output. After the power supply adapter receives a fast charging instruction command issued by a charging control module, output voltage is adjusted according to the battery voltage fed back by the charging control module. When the output voltage meets a fast charging voltage condition preset by the charging control module, the power supply adapter adjusts output current and the output voltage according to a fast charging current value and a fast charging voltage value to fast charge the battery, and at the same time the charging control module imports direct current from the power supply adapter to charge the battery. In a fast charging process, the power supply adapter adjusts the output current in real time according to the output voltage and the battery voltage, thus the battery is fast charged by adjusting the output current and the output voltage of the power supply adapter.
