Abstract

The invention belongs to the technical field of charging, and provides a battery charging device and a battery charging protection control method. A power supply adaptor in the battery charging device is in data communication with a charging control module; when it is judged by the power supply adaptor that overvoltage and / or overcurrent of direct current output by a communication interface of the power supply adaptor happens, the power supply adaptor informs the charging control module to drive a controller in electronic equipment to close a communication interface of the electronic equipment and direct current output is stopped automatically; when it is judged that overvoltage and / or overcurrent happens when the charging control module receives output voltage and output current of the power supply adaptor, the charging control module informs the power supply adaptor to stop direct current output and drives the controller in the electronic equipment to close the communication interface of the electronic equipment. In this way, overvoltage and / or overcurrent protection of a battery can be achieved when overvoltage and / or overcurrent output of the communication interface of the power supply adaptor happens.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a battery charging device and a battery charging protection control method. Background technique [0002] At present, the batteries in most electronic devices are charged by connecting them to external power adapters through the communication interface of the electronic devices. In the process of charging the batteries, in order to shorten the charging time, the existing technology can increase the charging current to achieve The purpose of fast charging the battery, however, whether the battery is charged with the conventional constant voltage output method or the method of increasing the charging current, if the charging voltage and / or charging current of the battery are too large during the charging process, Otherwise, the battery will be damaged due to overvoltage and / or overcurrent charging. Therefore, the prior art cannot protect the battery from overvoltage a...
