这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.
在介绍本公开提供的充电保护方法之前，首先对本公开所涉及应用场景进行介绍，该应用场景可以包括一电子设备以及一充电器。该电子设备可以为支持直充充电，包含电源管理芯片并且能够与充电设备进行有线或者无线信号传递的移动终端设备，例如可以是智能手机、平板电脑、智能电视、智能手表、PDA(Personal Digital Assistant，个人数字助理)、便携计算机等。该充电器可以为与上述移动终端设备匹配的支持直充充电，包含电源管理芯片并且能够与移动终端设备进行有线或者无线信号传递的充电设备。Before introducing the charging protection method provided by the present disclosure, the application scenario involved in the present disclosure is firstly introduced, and the application scenario may include an electronic device and a charger. The electronic device can be a mobile terminal device that supports direct charging, includes a power management chip, and can perform wired or wireless signal transmission with the charging device, such as a smart phone, a tablet computer, a smart TV, a smart watch, a PDA (Personal Digital Assistant , personal digital assistants), portable computers, etc. The charger can be a charging device that supports direct charging matching with the above-mentioned mobile terminal equipment, includes a power management chip and can perform wired or wireless signal transmission with the mobile terminal equipment.
图1是根据一示例性实施例示出的一种充电保护方法的流程图，如图1所示，该充电保护方法可以应用于上述应用场景中所述的电子设备，该方法可以包括以下步骤。Fig. 1 is a flow chart of a charging protection method according to an exemplary embodiment. As shown in Fig. 1, the charging protection method may be applied to the electronic device described in the above application scenario, and the method may include the following steps.
在步骤101中，获取充电器输出的第一电压，该第一电压为该充电器未输出充电电流时该充电器的充电线接口处的电压。In step 101, a first voltage output by a charger is obtained, and the first voltage is a voltage at a charging line interface of the charger when the charger does not output a charging current.
示例地，该第一电压可以为充电器在不输出充电电流的情况下，输出的一个固定电压V1。通常该第一电压至少为4.4V，并且可以根据实际应用需要进行设置。其中，在输出该第一电压时，充电器会无法避免地输出一个较小的电流，例如3mA，由于该电流相对于充电电流极小，不影响后续的阻抗计算，可以认为充电器未输出充电电流。而由于充电器未输出充电电流，电子设备端的接口处的电压值同样也是V1。该电子设备可以通过充电管理芯片记录该电压值V1。For example, the first voltage may be a fixed voltage V1 output by the charger when the charger does not output the charging current. Usually, the first voltage is at least 4.4V, and can be set according to actual application requirements. Among them, when outputting the first voltage, the charger will inevitably output a small current, such as 3mA. Since this current is extremely small relative to the charging current, it does not affect the subsequent impedance calculation. It can be considered that the charger does not output the charging current. current. Since the charger does not output the charging current, the voltage value at the interface of the electronic device is also V1. The electronic device can record the voltage value V1 through the charging management chip.
在步骤102中，获取该充电器输出的第一充电电流，该第一充电电流小于预设的电流阈值。In step 102, a first charging current output by the charger is obtained, and the first charging current is smaller than a preset current threshold.
在步骤103中，获取该充电器输出该第一充电电流时，该电子设备的充电线接口处的第二电压。In step 103, the second voltage at the charging line interface of the electronic device is acquired when the charger outputs the first charging current.

示例地，由于BC1.2或者QC协议的充电电流通常不会超过3A，而PD协议的充电电流会大于3A，所以当与该充电器进行充电协议握手成功后，可以检测该充电协议的类型。如果该充电协议为是BC1.2或者QC协议，则不激活检测阻抗线的功能。如果是PD协议，则该电子设备会告知充电器激活检测阻抗线的功能。For example, because the charging current of the BC1.2 or QC protocol usually does not exceed 3A, but the charging current of the PD protocol is greater than 3A, so after the charging protocol handshake with the charger is successful, the type of the charging protocol can be detected. If the charging protocol is BC1.2 or QC protocol, the function of detecting impedance line will not be activated. If it is a PD protocol, the electronic device will inform the charger to activate the function of detecting the impedance line.

The module for charging protection and voltage acquisition is used to determine whether to activate the impedance monitoring function, and collect the voltage at the interface 606 after activating the impedance monitoring function. Based on this, the impedance of the charging line is calculated, and the subsequent charging operation is controlled according to the impedance. The switch control module is used to control the opening and closing of the switches B and C, so as to cut off or connect the charging current provided to the battery. The charging protection method provided by the present invention can be realized in the following manner:
当电子设备检测该充电器601通过该充电线602接入该电子设备时，与该充电器601进行充电协议握手。当与该充电器601进行充电协议握手成功后，根据握手成功的充电协议判断是否激活阻抗检测功能。当确定激活该阻抗检测功能时，该电子设备通过信号告知该充电器601激活该阻抗检测功能，该充电器601在未输出充电电压的情况下输出一个固定电压V1。这时，由于接口605与接口606的电压值都为V1，该电源管理芯片603能够获取并储存V1。When the electronic device detects that the charger 601 is connected to the electronic device through the charging cable 602 , it performs a charging protocol handshake with the charger 601 . After the handshake of the charging protocol with the charger 601 is successful, it is determined whether to activate the impedance detection function according to the charging protocol of the successful handshaking. When it is determined to activate the impedance detection function, the electronic device informs the charger 601 to activate the impedance detection function through a signal, and the charger 601 outputs a fixed voltage V1 under the condition of not outputting the charging voltage. At this time, since the voltage values of the interface 605 and the interface 606 are both V1, the power management chip 603 can acquire and store V1.
