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发明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、本发明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.

随着充电芯片技术的革新，大功率充电方案不断出现，带来了不同的充电体验。同时，也引入了安全性问题。由于充电方案的优越性和目前充电线阻抗的无标准性，当使用大功率充电器充电时，如果引用阻抗不一样的充电线，一来降低充电体验，延长充电时间；二来可能会导致充电器无法正常工作，更有甚者，会造成手机侧，或者充电器侧的损坏。With the innovation of charging chip technology, high-power charging solutions continue to emerge, bringing different charging experiences. At the same time, security issues are also introduced. Due to the superiority of the charging solution and the current non-standard impedance of the charging line, when using a high-power charger to charge, if a charging line with a different impedance is used, it will reduce the charging experience and prolong the charging time; The charger cannot work normally, what's more, it will cause damage to the mobile phone side or the charger side.

图1为根据一示例性实施例提供的一种充电控制方法的示意图。充电器501通过充电线506与移动终端中的电源管理芯片503相连，电源管理芯片503与移动终端中的电池502相连，接口504为充电器的输出接口，接口505为移动终端的输入接口，充电线506通过接口504接入充电器501，且充电线506通过接口505接入移动终端的电源管理芯片503。Fig. 1 is a schematic diagram of a charging control method provided according to an exemplary embodiment. The charger 501 is connected to the power management chip 503 in the mobile terminal through the charging line 506, the power management chip 503 is connected to the battery 502 in the mobile terminal, the interface 504 is the output interface of the charger, and the interface 505 is the input interface of the mobile terminal. The line 506 is connected to the charger 501 through the interface 504 , and the charging line 506 is connected to the power management chip 503 of the mobile terminal through the interface 505 .

在电源管理芯片503中，包括用于进行充电保护及电压采集的模块，以及开关控制模块。其中，进行充电保护和电压采集的模块用于判断是否激活阻抗检测功能，并在激活阻抗检测功能后获取接口504处的第一电压V1、以及输出第一充电电流I时接口505处的第二电压V2。The power management chip 503 includes a module for charging protection and voltage acquisition, and a switch control module. Among them, the module for charging protection and voltage collection is used to judge whether to activate the impedance detection function, and obtain the first voltage V1 at the interface 504 and the second voltage V1 at the interface 505 when the first charging current I is output after the impedance detection function is activated. Voltage V2.

图2是根据一示例性实施例示出的一种充电控制方法的流程图，该充电控制方法应用于移动终端中，该方法包括以下步骤：Fig. 2 is a flowchart showing a charging control method according to an exemplary embodiment, the charging control method is applied in a mobile terminal, and the method includes the following steps:

S101：与充电器进行充电协议握手。S101: Perform a charging protocol handshake with the charger.

在本实施例中，当充电器的输出接口与移动终端的输入接口之间连接充电线后，移动终端与充电器之间进行充电协议的握手。充电协议可包括：电池充电协议1.2(BC1.2)、快充协议2.0(QC2.0)、快充协议3.0(QC3.0)、功率传输协议(PD协议)或者私有协议等。In this embodiment, after the charging cable is connected between the output interface of the charger and the input interface of the mobile terminal, a charging protocol handshake is performed between the mobile terminal and the charger. The charging protocol may include: battery charging protocol 1.2 (BC1.2), fast charging protocol 2.0 (QC2.0), fast charging protocol 3.0 (QC3.0), power transmission protocol (PD protocol) or proprietary protocol, etc.

当移动终端与充电器握手不成功时，该方法包括：充电器不对移动终端进行充电。例如，充电器不输出电流。When the handshake between the mobile terminal and the charger fails, the method includes: the charger does not charge the mobile terminal. For example, a charger does not output current.

S102：当充电协议握手成功后，根据握手成功的充电协议判断是否启动阻抗检测功能。S102: After the charging protocol handshake is successful, judge whether to start the impedance detection function according to the charging protocol with the successful handshaking.

在S102中，可能包括：In S102, may include:

判断握手成功的充电协议是否属于预设充电协议；Determine whether the charging protocol with a successful handshake belongs to the default charging protocol;

当握手成功的充电协议属于预设充电协议时，确定启动阻抗检测功能；当握手成功的充电协议不属于预设充电协议时，确定不启动阻抗检测功能。When the charging protocol with successful handshake belongs to the preset charging protocol, it is determined to start the impedance detection function; when the charging protocol with successful handshake does not belong to the preset charging protocol, it is determined not to start the impedance detection function.

此处，预设充电协议可能包括：允许利用大于第一电流阈值的充电电流进行充电的协议。其中，第一电流阈值可为4A。Here, the preset charging protocol may include: a protocol allowing charging with a charging current greater than the first current threshold. Wherein, the first current threshold may be 4A.

当充电线的过流能力在3A以下时，充电电流按照现有充电线的阻抗进行大功率充电时，充电线的阻抗对充电效果影响较小。但当电流达到5A以上，在进行大功率充电时，为了保证充电效果和充电安全，对充电线的阻抗要求就非常高，充电线的阻抗需要在预设阻抗范围内(例如充电线的阻抗需要小于100毫欧姆)。When the over-current capability of the charging line is below 3A, the charging current will perform high-power charging according to the impedance of the existing charging line, and the impedance of the charging line will have little influence on the charging effect. However, when the current reaches above 5A, in order to ensure the charging effect and charging safety, the impedance requirement of the charging line is very high during high-power charging. The impedance of the charging line needs to be within the preset impedance range (for example, the impedance of the charging line needs to be less than 100 milliohms).

由于PD协议或者私有协议支持充电线3A以上的充电能力，其他充电协议的充电线过流能力基本都在3A以下。此时，预设充电协议可为PD协议或私有协议。Since the PD protocol or private protocol supports the charging capacity of the charging line above 3A, the overcurrent capacity of the charging line of other charging protocols is basically below 3A. At this time, the preset charging protocol may be a PD protocol or a private protocol.

当移动终端确定握手成功的充电协议不是预设充电协议时，移动终端向充电器发送控制指令，控制充电器对移动终端进行充电。此时，处于安全因素考虑，充电器的输出电流小于或等于第一电流阈值。具体地，第一电流阈值可以根据充电协议或充电线的性能决定确定。例如，当充电协议为私有协议时，第一电流阈值可为4A。When the mobile terminal determines that the charging protocol with a successful handshake is not the preset charging protocol, the mobile terminal sends a control command to the charger to control the charger to charge the mobile terminal. At this time, for safety reasons, the output current of the charger is less than or equal to the first current threshold. Specifically, the first current threshold may be determined according to the charging protocol or the performance of the charging line. For example, when the charging protocol is a private protocol, the first current threshold may be 4A.

当判断握手成功的充电协议是预设充电协议时，例如，握手成功的充电协议是PD协议或者私有协议，则移动终端确定激活检测阻抗线阻抗的功能，进而根据充电线的阻抗选择充电架构和充电策略。When it is judged that the charging protocol with a successful handshake is the preset charging protocol, for example, the charging protocol with a successful handshake is a PD protocol or a proprietary protocol, the mobile terminal determines to activate the function of detecting impedance line impedance, and then selects the charging architecture and charging strategy.

S103：当确定启动阻抗检测功能时，获取充电器输出接口处的第一电压；其中，充电器的输出接口处和移动终端的输入接口处连接有充电线。S103: When it is determined to start the impedance detection function, acquire the first voltage at the output interface of the charger; wherein, the output interface of the charger and the input interface of the mobile terminal are connected with a charging line.

在S103中，参照图1所示，第一电压可为在充电器501输出电流较小(例如充电器501输出电流为3mA)时，采集的充电器501的输出接口504处的电压，记为V1。此处，由于3mA的输出电流相较于充电器的第一充电电流很小，不影响对于充电线的阻抗计算，因此可以忽略不计。In S103, referring to FIG. 1, the first voltage may be the voltage at the output interface 504 of the charger 501 collected when the output current of the charger 501 is small (for example, the output current of the charger 501 is 3mA), which is denoted as V1. Here, since the output current of 3 mA is small compared with the first charging current of the charger, it does not affect the calculation of the impedance of the charging line, so it can be ignored.

S104：向充电器发送第一控制指令；其中，第一控制指令，用于控制充电器以预设步长值从初始充电电流值逐步增大输出的第一充电电流。S104: Send a first control instruction to the charger; wherein, the first control instruction is used to control the charger to gradually increase the output first charging current from the initial charging current value with a preset step value.

在S104中，预设步长值和初始充电电流可根据充电协议进行确定。例如，预设步长值可能为200mA，初始充电电流可能为100mA。此时，S104可包括：向充电器发送第一控制指令，控制充电器以涓流充电方式向移动终端进行充电。In S104, the preset step value and the initial charging current can be determined according to the charging protocol. For example, the preset step value might be 200mA and the initial charge current might be 100mA. At this time, S104 may include: sending a first control instruction to the charger, and controlling the charger to charge the mobile terminal in a trickle charging manner.

具体地，移动终端为手机时，手机通过配置通道引脚(CC pin)与充电器沟通，向充电器发送第一控制指令，用于控制充电器按照输出电压为9V、初始充电电流值为100mA的标准向手机输出能量；然后以200ms为一个时间周期，每间隔200ms，以200mA为预设步长值逐步增大第一充电电流，直至第一充电电流增大到预设稳定充电电流。此处，预设稳定充电电流可根据充电协议或充电线的性能确定。例如，当充电协议为PD协议或私有协议时，预设稳定充电电流可为2A。Specifically, when the mobile terminal is a mobile phone, the mobile phone communicates with the charger through the configuration channel pin (CC pin), and sends the first control command to the charger, which is used to control the charger according to the output voltage of 9V and the initial charging current value of 100mA. The standard output energy to the mobile phone; then take 200ms as a time period, every 200ms, and use 200mA as the preset step value to gradually increase the first charging current until the first charging current increases to the preset stable charging current. Here, the preset stable charging current can be determined according to the charging protocol or the performance of the charging cable. For example, when the charging protocol is a PD protocol or a proprietary protocol, the preset stable charging current may be 2A.

相较于在输出稳定的充电电流过程中对充电线阻抗进行检测，进而选择充电策略，通过控制充电器以预设步长值从初始充电电流值逐步增大充电器输出的第一充电电流，以供移动终端可在第一充电电流逐步增大的阶段对充电线阻抗进行检测，一方面，移动终端可以根据多个第一充电电流进行阻抗的精确检测，从而提高了阻抗计算的准确性，进而提高了充电策略选择的准确性，保证充电安全性。Compared with detecting the impedance of the charging line during the process of outputting a stable charging current, and then selecting a charging strategy, by controlling the charger to gradually increase the first charging current output by the charger from the initial charging current value with a preset step value, In order for the mobile terminal to detect the impedance of the charging line when the first charging current gradually increases, on the one hand, the mobile terminal can accurately detect the impedance according to multiple first charging currents, thereby improving the accuracy of impedance calculation, In turn, the accuracy of charging strategy selection is improved, and charging safety is ensured.

另一方面，将充电线的阻抗检测提前到输出稳定充电电流之前，移动终端可以直接根据已经检测到的充电线的阻抗提供稳定充电电流，降低了因为稳定的充电电流过大导致充电线、充电器或移动终端损坏的风险。On the other hand, if the impedance detection of the charging line is advanced before the stable charging current is output, the mobile terminal can directly provide a stable charging current according to the detected impedance of the charging line, which reduces the risk of charging lines and charging caused by the stable charging current being too large. risk of damage to the device or mobile terminal.

S105：针对每一个第一充电电流，获取移动终端的输入接口处的第二电压。S105: For each first charging current, acquire a second voltage at an input interface of the mobile terminal.

参照图1所示，第二电压可为接口505处的电压，记为V2。此时，充电器501的输出电流为第一充电电流I。该第一充电电流I通过接口504、经充电线506，输入接口505，进而对移动终端进行充电。Referring to FIG. 1 , the second voltage may be the voltage at the interface 505 , denoted as V2 . At this time, the output current of the charger 501 is the first charging current I. The first charging current I is input to the interface 505 through the interface 504, through the charging line 506, and then charges the mobile terminal.

S106：根据第一电压、第二电压和第一充电电流，计算充电线的阻抗。S106: Calculate the impedance of the charging line according to the first voltage, the second voltage and the first charging current.

由于第一电压V1为充电器501输出电流较小(例如充电器501输出电流为3mA)时，采集的充电器501的输出接口504处的电压，较小的输出电流(3mA)相较于充电器501的第一充电电流很小，不影响对于充电线的阻抗计算，可以忽略不计。因此，根据欧姆定律(电阻＝电压/电流)，充电线的阻抗R＝(V1-V2)/I。Since the first voltage V1 is the voltage at the output interface 504 of the charger 501 collected when the output current of the charger 501 is small (for example, the output current of the charger 501 is 3mA), the smaller output current (3mA) is compared with charging The first charging current of the charger 501 is very small, does not affect the impedance calculation of the charging line, and can be ignored. Therefore, according to Ohm's law (resistance=voltage/current), the impedance R=(V1-V2)/I of the charging line.

在S106中，可能包括：In S106, may include:

分别根据每一个第一充电电流，及各自对应的第一电压及第二电压，计算充电线在每个第一充电电流状态下的第一阻抗，并计算多个第一阻抗的方差。Calculate the first impedance of the charging line in each first charging current state according to each first charging current and the corresponding first voltage and second voltage respectively, and calculate the variance of the plurality of first impedances.

本公开实施例中，根据所得的方差与预设方差阈值之间的比较结果，设置了如下两种获得阻抗的方式：In the embodiment of the present disclosure, according to the comparison result between the obtained variance and the preset variance threshold, the following two ways of obtaining impedance are set:

方式一：method one:

若方差小于或等于预设方差阈值，则确定多个第一阻抗的平均值为充电线的阻抗。If the variance is less than or equal to the preset variance threshold, the average value of the plurality of first impedances is determined as the impedance of the charging line.

当电池电压从低于预设饱和电压经过充电达到预设饱和电压时，向充电器发送第四控制指令；其中，第四控制指令，用于控制充电器减小输出电流。When the battery voltage reaches the preset saturation voltage after being charged from being lower than the preset saturation voltage, a fourth control command is sent to the charger; wherein, the fourth control command is used to control the charger to reduce the output current.

在充电过程中，由于电池内部有阻抗，在电池充电电流较大的情况下，电池电压增加的速率很快，使得电池电压迅速增加至预设饱和电压。此时，由于充电线存在阻抗，充电线两端的压降较大，使得给电池充电的输入电压小于电池电压，导致电池虽然没有实际达到充电饱和状态，但无法继续进行充电。此处，预设饱和电压可以根据充电协议或电池额定电压确定。例如，当电池额定电压为10V时，预设饱和电压可设置为8.8V。During the charging process, due to the internal impedance of the battery, the battery voltage increases rapidly when the battery charging current is large, so that the battery voltage rapidly increases to the preset saturation voltage.

When the output current of the charger is greater than the first current threshold, the mobile terminal sends a fourth control instruction to the charger again, for controlling the charger to reduce the output current. This cycle continues until the output current of the charger decreases to the first current threshold.

当充电器的输出电流减小到等于第一电流阈值时，移动终端输出的第五控制指令，以使充电器切换至上述可控低阻抗,MOS架构的低压充电模式。When the output current of the charger is reduced to be equal to the first current threshold, the mobile terminal outputs a fifth control command to switch the charger to the above-mentioned controllable low-impedance, MOS low-voltage charging mode.

在本实施例中，当充电器的输出电流减小到等于第一电流阈值时，通过减小输出电压，减小充电线的发热量，降低能量损耗，提高充电效率。In this embodiment, when the output current of the charger is reduced to be equal to the first current threshold, by reducing the output voltage, the heating value of the charging line is reduced, the energy loss is reduced, and the charging efficiency is improved.

综上所述，相较于在输出稳定的充电电流过程中对充电线阻抗进行检测，进而选择充电策略，本公开提供的充电控制方法，在从初始充电电流值逐步增大充电器输出电流的过程中，对充电线阻抗进行检测，并根据检测的阻抗确定充电策略，一方面，可以根据多个第一充电电流进行阻抗的精确检测，从而提高了阻抗计算的准确性，进而提高了充电策略选择的准确性，保证充电安全性。另一方面，将充电线的阻抗检测提前到输出稳定充电电流之前，如此，可以直接根据已经检测到的充电线的阻抗提供稳定充电电流，降低了因为稳定的充电电流过大导致充电线、充电器或移动终端损坏的风险。To sum up, compared with detecting the impedance of the charging line during the process of outputting a stable charging current, and then selecting a charging strategy, the charging control method provided by the present disclosure gradually increases the output current of the charger from the initial charging current value. In the process, the impedance of the charging line is detected, and the charging strategy is determined according to the detected impedance.

When the mobile terminal judges that the variance is greater than the preset variance threshold, the charger stops outputting current based on the sixth control instruction of the mobile terminal, which reduces the risk of damage to the charger, charging line and mobile terminal, and ensures charging safety.
