Abstract
The present disclosure provides a battery charging apparatus and a battery charging protection control method. A power adapter in the battery charging apparatus performs data communication with a charging control circuit; when the power adapter determines that overvoltage and/or overcurrent occurs in the direct current output by a communication interface of the power adapter, the power adapter notifies the charging control circuit to drive a controller in the electronic device to switch off a communication interface of the electronic device and switches off the direct current output automatically; when the charging control circuit determines that overvoltage and/or overcurrent occurs upon receiving output voltage and output current of the power adapter, the charging control circuit notifies the power adapter to switch off the direct current output and drives the controller in the electronic device to switch off the communication interface of the electronic device.
