1. A mobile electronic system, comprising:
a mobile electronic device, comprising a first connector and a first battery, wherein the first connector comprises a first pin, a second pin and a fifth pin, wherein the first pin and the second pin are coupled to the first battery, and the fifth pin is coupled to a ground of the mobile electronic device; and a charging accessory, comprising a second connector, wherein the second connector comprises a third pin, a fourth pin and a sixth pin, wherein the third pin and the fourth pin are coupled to the charging accessory, and the sixth pin is coupled to a ground of the charging accessory, wherein the first connector and the second connector are configured to couple the mobile electronic device and the charging accessory, wherein when the mobile electronic device and the charging accessory are coupled with each other through the first connector and the second connector, the first pin is coupled to the third pin, the second pin is coupled to the fourth pin, and the fifth pin and the sixth pin are coupled with each other and become a common ground of the mobile electronic device and the charging accessory, wherein when the charging accessory is coupled to an alternating-current voltage and the mobile electronic device, the charging accessory converts the alternating-current voltage into a first direct-current voltage, detects an instantaneous voltage of the first battery, determines a value of the first direct-current voltage according to the instantaneous voltage, and outputs the first direct-current voltage to charge the first battery, wherein the charging accessory outputs the first direct-current voltage through the first pin, the third pin, the fifth pin and the sixth pin to charge the first battery, and the charging accessory detects the instantaneous voltage through the second pin, the fourth pin, the fifth pin and the sixth pin. |
