Title: TERMINAL AND BATTERY CHARGING CONTROL DEVICE AND METHOD THEREFOR
Abstract:
The present invention relates to the technical field of charging. A terminal and a battery charging control device and method therefor. The battery charging control device comprising a battery connector, a main control module and a fast charge switch module is adopted. During normal charge or fast charge of a battery in the terminal, the main control module carries out data communication with an external power adapter through a communication interface of the terminal, and obtains a charging voltage and a charging current of the battery; and if the charging voltage is larger than a voltage threshold and/or the charging current is larger than a current threshold, the main control module sends a charging OFF command so that a controller of the terminal disables the communication interface of the terminal, thereby achieving overvoltage and/or overcurrent protection on the battery.
