A charging processing method is applied to charging equipment and is characterized in that the charging equipment comprises an adapter and a connecting wire, the adapter comprises a charging interface and a control chip, the connecting wire is used for being connected with the adapter through the charging interface, the interface of the connecting wire comprises an ID pin, and the ID pin is connected to the control chip through the connecting wire; the method comprises the following steps:
when the adapter charges the equipment to be charged, acquiring the level information of the ID pin;
the charging method comprises the steps of obtaining charging information of equipment to be charged according to communication pins of a charging interface, judging whether a connecting wire is connected with an adapter or not according to level information of an ID pin, wherein the adapter is provided with two different interfaces, namely a Micro USB interface and a USB Type-C interface, and if yes, reducing charging power when the adapter charges the equipment to be charged according to the charging information.
8. The method of claim 7, wherein determining whether the connection line is connected to the adapter according to the level information of the ID pin comprises:
when the ID pin is at a low level, determining that the connecting line is connected to the adapter;
and when the ID pin is at a high level, determining that the connecting line is not connected with the adapter.
9. The charging processing method according to claim 7, wherein the step of reducing the charging power of the adapter includes: reducing a charging current of the adapter and/or reducing a charging voltage of the adapter.
10. An electronic device comprising a charging circuit and a battery, the charging circuit being connected to the battery, the charging circuit as claimed in any one of claims 1-6.
11. A computer-readable storage medium, on which a computer program is stored, which, when being executed by a processor, carries out the steps of the charging processing method according to any one of claims 7 to 9.
