Embodiment 1

[0051] figure 1 It is a schematic flow chart of the method for reducing the heating of the charging cable according to Embodiment 1 of the present invention, as shown in figure 1 As shown, the method for reducing heating of the charging cable in this example includes the following steps:

[0052] Step 101 , detect whether there is a charging connector plugged into the charging port of the electronic device, and sometimes execute step 102 .

[0053] In this step, when the charging port of the electronic device is connected with the charging connector, the electronic device will detect the voltage change of the charging port, so as to determine whether the charging port is connected with the charging connector. After the charging connector is connected to the charging port, the charging circuit in the electronic device will also generate current, so that the connection of the charging connector can also be judged. The electronic device can easily determine whether the chargin...

[0069] figure 2 It is a schematic flow chart of the method for reducing the heating of a charging cable according to Embodiment 2 of the present invention, as shown in figure 2 As shown, the method for reducing heating of the charging cable in this example includes the following steps:

[0070] Step 201, detect whether there is a charging connector plugged into the charging port of the electronic device, sometimes step 202 is executed.

[0071] In this step, when the charging port of the electronic device is connected with the charging connector, the electronic device will detect the voltage change of the charging port, so as to determine whether the charging port is connected with the charging connector. After the charging connector is connected to the charging port, the charging circuit in the electronic device will also generate current, so that the connection of the charging connector can also be judged. The electronic device can easily determine whether the charging p...

Abstract

The embodiments of the invention disclose a method for reducing heating of a charging cable, and an electronic device. The method comprises the following steps: when it is detected that a charging joint is inserted into a charging port of the electronic device, calculating a first electrical parameter of the charging cable connected with the charging joint; according to the first electrical parameter, determining maximum charging threshold currents of the charging cable; and generating a second instruction, and sending the second instruction to a charging adapter connected with the charging cable to enable currents output by the charging adapter to the charging cable to be smaller than and equal to the maximum charging threshold currents.

Description

technical field [0001] Embodiments of the present invention relate to electronic device charging technologies, and in particular to a method for reducing heating of a charging cable and electronic devices. Background technique [0002] In order to meet the longer battery life of electronic devices, the battery capacity is getting larger and larger, and the corresponding charging time of the battery is getting longer and longer, so fast charging technology has emerged as the times require. The fast charging system consists of a charging adapter (Adapter), a data cable (Cable) and a host (Host), but people often only pay attention to the charging adapter and the host, and seldom pay attention to the Cable, thinking that as long as the charging head and the host support fast charging, any It can be matched. However, if the impedance of the data line is too large, it will easily cause the data line to overheat, thereby greatly reducing the user experience. Contents of the inv...
