Abstract

The invention relates to a charging input control device, a terminal, a charging output control device, equipment, and a control method. The charging input control device is applied to a terminal and is connected with a charging input connector of the terminal, and the charging input connector includes an input communication line. The charging input control device is characterized in that the device comprises a charging coding unit which is used for sending a charging identification signal through the input communication line and outputting a charging switching signal according to a received identification feedback signal corresponding to the charging identification signal. According to the invention, a communication connection is established through the charging input connector and a charging output connector, the charging switching signal is output according to the received identification feedback signal corresponding to the charging identification signal, and a charging decoding unit of the charging output control device performs decoding to control the output voltage, current and the like. The advantage of stable and reliable communication is achieved.

Description

technical field [0001] The invention relates to the technical field of electronic terminal control, in particular to a charging input control device for a terminal and an electronic terminal. Background technique [0002] With the improvement of the configuration of portable devices, especially smart portable devices, the power consumption of portable devices is also increasing. In recent years, the battery capacity improvement technology with the same volume has encountered a bottleneck, which can no longer meet the battery life requirements of smart portable devices, resulting in more frequent charging of portable devices and longer and longer charging time. [0003] In order to shorten the charging time, it is necessary to use a larger power to charge the battery. In order to realize the closed-loop controllable charging process between charging equipment and portable equipment, solve the detection and protection of overvoltage, overcurrent, and overheating in the chargi...
