Abstract

The invention belongs to the technical field of charging, and provides an electronic device and a power adapter of the electronic device. The power adapter comprising a power source module, a master control module, an electric level adjustment module, a current detection module, a voltage detection module and an output switch module is provided for the electronic device, the master control module judges whether the output current of the power adapter is larger than a current threshold and whether the output voltage of the power adapter is larger than a voltage threshold, and if the output current is larger than the current threshold and / or the output voltage is larger than the voltage threshold, the master control module controls the output switch module to close direct current electricity output of the power adapter. In addition, if the electronic device judges that the output of the power adapter has an overcurrent and / or overvoltage phenomenon and feeds a charging closing instruction back to the master control module, the master control module controls the output switch module to close the direct current electricity output of the power adapter according to the charging closing instruction, and therefore the purpose of achieving overcurrent and / or overvoltage protection is achieved for a battery.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to an electronic device and a power adapter thereof. Background technique [0002] At present, most electronic devices obtain DC power from the power adapter through their communication interface to charge the battery. In the process of charging the battery, in order to shorten the charging time, the existing technology can increase the output current of the power adapter to achieve fast charging of the battery. However, no matter whether the battery is charged by the conventional constant voltage output method or the method of increasing the output current, if the output voltage and / or output current of the power adapter are too large during the charging process of the battery , the battery will be damaged by overvoltage and / or overcurrent charging. Therefore, the prior art cannot protect the battery from overvoltage and / or overcurrent when the battery in the electron...
