Abstract

The invention belongs to the technical field of charging and provides a terminal, and a battery charging control device and method. The battery charging control device comprising a battery connector, a master control module and a rapid charging switch module is adopted, in the process of carrying out conventional charging or quick charging on a battery in the terminal, data communication is carried out between the master control module and an external power adapter through a communication interface of the terminal, and the charging voltage and the charging current of the battery are obtained. If the charging voltage is larger than the voltage threshold value and / or the charging current is larger than the current threshold value, the master control module sends a charging cut-off instruction to enable a controller of the terminal to shut down the communication interface of the terminal, so the purpose of overvoltage and / or overcurrent protection on the battery is achieved.

Description

technical field [0001] The invention belongs to the technical field of charging, and in particular relates to a terminal and a battery charging control device and method thereof. Background technique [0002] At present, the battery in most terminals is charged by connecting to an external power adapter through the communication interface of the terminal, and in the process of charging the battery, in order to shorten the charging time, the existing technology can increase the charging current to achieve the charging of the battery. The purpose of fast charging, however, whether the battery is charged by 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, it will cause The battery has been damaged by over-voltage and / or over-current charging. Therefore, the prior art cannot implement overvoltage and / or overcurrent protection...
