具体实施方式Detailed ways
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.
本公开实施例适用于利用充电泵对电池进行充电的终端设备。充电泵的基本原理是给电容充电，把电容从充电电路取下以隔离充进的电荷，然后连接到另一个电路上，传递刚才隔离的电荷。The embodiments of the present disclosure are applicable to a terminal device that uses a charge pump to charge a battery. The basic principle of the charge pump is to charge the capacitor, remove the capacitor from the charging circuit to isolate the charge, and then connect it to another circuit to transfer the charge just isolated.
在采用电荷泵对电池进行充电的过程中，电荷泵的输入电压通常满足以下要求：电荷泵的输入电压与被充电电池的电压成正比，例如电荷泵的输入电压是被充电电池的电压的2倍。这样，电池的电压因为充电的原因逐渐增大，电荷泵的输入电压也会随之增大。In the process of using the charge pump to charge the battery, the input voltage of the charge pump usually meets the following requirements: the input voltage of the charge pump is proportional to the voltage of the charged battery, for example, the input voltage of the charge pump is 2 times the voltage of the charged battery times. In this way, the voltage of the battery increases gradually due to charging, and the input voltage of the charge pump also increases accordingly.
电池的充电电流是由电池的化学性质来决定的。常见的充电电流一般是电池容量的倍数，例如，通常是1C～1.5C，即电池额定容量C的1倍或者1.5倍。电池的容量通常以安培·小时(简称A·h)为单位。The charging current of the battery is determined by the chemical properties of the battery. A common charging current is generally a multiple of the battery capacity, for example, usually 1C to 1.5C, that is, 1 or 1.5 times the rated capacity C of the battery. The capacity of a battery is usually measured in ampere-hours (Ah for short).
这个充电电流会在充电开始阶段设置作为电荷泵的最大输入电流。相关技术中，该充电电流在采用电荷泵进行充电的整个充电过程中，是固定不变的。假如采用的电池的充电电流为1.5C，当电荷泵输入电压较低的时候，可以采用1.5C的电流为电池充电。电池充电一段时间后，电池的电压增大，电荷泵的输入电压也随之增大，由于电荷泵的输出功率等于电荷泵的输入电压的二分之一乘以电荷泵的输入电流，若电荷泵的输入电流维持1.5C不变，则电荷泵的输出功率也会随着电荷泵的输入电压的增大而增大，从而可能出现电荷泵的输出功率超过电池额定功率的问题。而如果将电荷泵的输入电流设置得过小，将会导致在充电过程的前期阶段，充电功率过小，充电效率较低。This charging current is set as the maximum input current to the charge pump at the beginning of charging. In the related art, the charging current is constant during the whole charging process using the charge pump. If the charging current of the battery used is 1.5C, when the input voltage of the charge pump is low, the current of 1.5C can be used to charge the battery. After the battery is charged for a period of time, the voltage of the battery increases, and the input voltage of the charge pump increases accordingly. Since the output power of the charge pump is equal to half of the input voltage of the charge pump multiplied by the input current of the charge pump, if the charge If the input current of the pump remains unchanged at 1.5C, the output power of the charge pump will also increase with the increase of the input voltage of the charge pump, which may cause the problem that the output power of the charge pump exceeds the rated power of the battery. However, if the input current of the charge pump is set too small, the charging power will be too small and the charging efficiency will be low in the early stage of the charging process.
为此，本公开实施例提供了一种基于电荷泵的充电方法和装置，能够有效控制电荷泵的输出功率，避免充电过程中出现电荷泵的输出功率超过电池额定功率的问题。To this end, embodiments of the present disclosure provide a charging method and device based on a charge pump, which can effectively control the output power of the charge pump and avoid the problem that the output power of the charge pump exceeds the rated power of the battery during charging.

Embodiments of the present disclosure may be applicable to the constant current charging phase.
图3是本公开实施例示出的一种充电方法的流程图。该方法适用于图1中的终端设备20，参见图3，该方法包括：Fig. 3 is a flow chart of a charging method shown in an embodiment of the present disclosure. The method is applicable to the terminal device 20 in FIG. 1, referring to FIG. 3, the method includes:
在步骤S31中，在采用电荷泵对电池充电的过程中，获取电荷泵的当前输入电压；In step S31, during the process of using the charge pump to charge the battery, the current input voltage of the charge pump is obtained;
在步骤S32中，获取电荷泵的输入电压与输入电流的对应关系，在该对应关系中，输入电压与输入电流为负相关关系；In step S32, the corresponding relationship between the input voltage and the input current of the charge pump is obtained, and in the corresponding relationship, the input voltage and the input current are negatively correlated;
在步骤S33中，基于该对应关系，确定当前输入电压对应的输入电流；In step S33, based on the corresponding relationship, the input current corresponding to the current input voltage is determined;
在步骤S34中，根据确定出的输入电流，控制电荷泵的输入电流。In step S34, the input current of the charge pump is controlled according to the determined input current.
在本公开实施例中，在采用电荷泵对电池的充电过程中，获取电荷泵的当前输入电压；获取电荷泵的输入电压与输入电流的对应关系；并基于该对应关系，确定当前输入电压对应的输入电流，由于在该对应关系中，输入电压与输入电流为负相关关系，所以随着电荷泵的输入电压的增大，确定出的电荷泵的输入电流逐渐减小。在这种情况下，根据确定出的输入电流，控制电荷泵的输入电流，可以达到随着输入电压的增大而减小电荷泵的输入电流的目的。由于电荷泵的输出功率等于电荷泵的输入电压的二分之一乘以电荷泵的输入电流，所以本公开实施例中的电荷泵的输入电流的调整方式可以减缓电荷泵的输出功率的上升趋势，避免电荷泵的输出功率超过电池的额定充电功率。In the embodiment of the present disclosure, in the process of charging the battery by using the charge pump, the current input voltage of the charge pump is obtained; the corresponding relationship between the input voltage and the input current of the charge pump is obtained; and based on the corresponding relationship, the current input voltage corresponding to The input current of the input current, because in this corresponding relationship, the input voltage and the input current are negatively correlated, so as the input voltage of the charge pump increases, the determined input current of the charge pump decreases gradually. In this case, controlling the input current of the charge pump according to the determined input current can achieve the purpose of reducing the input current of the charge pump as the input voltage increases. Since the output power of the charge pump is equal to one-half of the input voltage of the charge pump multiplied by the input current of the charge pump, the adjustment method of the input current of the charge pump in the embodiments of the present disclosure can slow down the rising trend of the output power of the charge pump , to avoid the output power of the charge pump exceeding the rated charging power of the battery.
图4是本公开实施例示出的一种充电方法的流程图。该方法适用于图1中的终端设备20，参见图4，该方法包括：Fig. 4 is a flowchart of a charging method shown in an embodiment of the present disclosure. This method is applicable to the terminal device 20 in Fig. 1, referring to Fig. 4, the method includes:
在步骤S41中，确定充电器类型。In step S41, the charger type is determined.
在本公开的一种实现方式中，充电器类型包括但不限于SDP(StandardDownstream Port，标准下行接口)充电器、CDP(ChargingDownstream Port，充电下行接口)充电器、DCP(Dedicated Charging Port，专用充电接口)充电器和PD(Power Delivery，功率传输)充电器、QC(Quick Charge，快速充电)2充电器、QC3充电器、QC4充电器等。其中，QC2、QC3、QC4为高通的私有协议。In an implementation of the present disclosure, the charger type includes but not limited to SDP (StandardDownstream Port, standard downstream interface) charger, CDP (ChargingDownstream Port, charging downstream interface) charger, DCP (Dedicated Charging Port, dedicated charging interface) ) chargers and PD (Power Delivery, power transmission) chargers, QC (Quick Charge, fast charging) 2 chargers, QC3 chargers, QC4 chargers, etc. Among them, QC2, QC3, and QC4 are Qualcomm's private protocols.
不同的充电器类型对应的电流、电压、功率等参数中的至少一种不同。例如，SDP对应的最大充电电流为500mA/USB2.0；900mA/USB3.0；CDP对应的最大充电电流为1500mA；DCP对应的最大充电电流为500mA～2000mA；由于这几种类型的充电器的输出电源是恒定的5V，所以最大充电电流与功率对应，最大充电电流的大小也可以反应出功率的大小。又例如，QC4充电器和PD充电器的功率为40w，QC3充电器的功率为18w。At least one of parameters such as current, voltage, and power corresponding to different charger types is different. For example, the maximum charging current corresponding to SDP is 500mA/USB2.0; 900mA/USB3.0; the maximum charging current corresponding to CDP is 1500mA; the maximum charging current corresponding to DCP is 500mA~2000mA; The output power is a constant 5V, so the maximum charging current corresponds to the power, and the maximum charging current can also reflect the power. For another example, the power of QC4 charger and PD charger is 40w, and the power of QC3 charger is 18w.
在该步骤S41中，若终端设备与充电器之间通过有线方式充电，例如通过USB数据线连接，则可以基于USB协议规定确定充电器类型。若终端设备与充电器之间通过无线方式充电，则可以在终端设备和充电器上分别配置无线通信模块，利用无线通信模块通信以获取充电器类型。In this step S41, if the terminal device and the charger are charged by a wired method, for example, connected by a USB data cable, the type of the charger may be determined based on the USB protocol. If wireless charging is used between the terminal device and the charger, wireless communication modules can be configured on the terminal device and the charger respectively, and the wireless communication module can be used to communicate to obtain the charger type.
在步骤S42中，判断确定出的充电器类型是否属于支持提供可变输出电压的充电器类型，若确定出的充电器类型属于支持提供可变输出电压的充电器类型，执行步骤S43；若确定出的充电器类型不属于支持提供可变输出电压的充电器类型，则退出当前流程。In step S42, it is judged whether the determined charger type belongs to the charger type that supports variable output voltage, if the determined charger type belongs to the charger type that supports variable output voltage, perform step S43; if determined If the selected charger type does not belong to the charger type that supports variable output voltage, exit the current process.
这里，可以预先存储支持提供可变输出电压的充电器类型的信息，例如标识，在预先存储的充电器类型中查找该确定出的充电器类型，若查找到该确定出的充电器类型，则表示该确定出的充电器类型属于支持提供可变输出电压的充电器类型；若没有查找到该确定出的充电器类型，则表示确定出的充电器类型不属于支持提供可变输出电压的充电器类型。Here, the information of the charger type that supports variable output voltage can be stored in advance, such as identification, and the determined charger type is searched in the pre-stored charger types. If the determined charger type is found, then Indicates that the determined charger type belongs to the charger type that supports variable output voltage; if the determined charger type is not found, it indicates that the determined charger type does not belong to the charger that supports variable output voltage device type.
示例性地，支持提供可变输出电压的充电器类型包括但不限于PD充电器、QC2充电器、QC3充电器、QC4充电器等。Exemplarily, the types of chargers that support variable output voltages include but are not limited to PD chargers, QC2 chargers, QC3 chargers, QC4 chargers, and the like.
本公开实施例中，可以优先判断充电器类型是否属于支持提供可变输出电压的充电器，若充电器类型不属于支持提供可变输出电压的充电器，则表示电荷泵的输入电压不可变，也不会存在由于电荷泵的输入电流增大而导致电荷泵的输出功率超过电池的额定充电功率的问题，所以无需执行本公开实施例中的方法。In the embodiment of the present disclosure, it can be prioritized to determine whether the charger type belongs to a charger that supports variable output voltage. If the charger type does not belong to a charger that supports variable output voltage, it means that the input voltage of the charge pump is not variable. There is also no problem that the output power of the charge pump exceeds the rated charging power of the battery due to the increase of the input current of the charge pump, so there is no need to implement the methods in the embodiments of the present disclosure.
需要说明的是，前述步骤S41～S42为可选步骤，在一次充电过程中，只需要执行一次即可。如果后续所有的充电器类型均能够提供可变输出电压，则该步骤S41～S42还可以直接省略。It should be noted that the foregoing steps S41 to S42 are optional steps, and only need to be performed once during a charging process. If all subsequent charger types can provide variable output voltages, steps S41 - S42 can also be omitted directly.
在步骤S43中，在采用电荷泵对电池充电的过程中，获取电荷泵当前的输入电压。In step S43, during the process of using the charge pump to charge the battery, the current input voltage of the charge pump is acquired.
示例性地，可以通过采样电路实时采集电荷泵的输入端的电压，即可得到电荷泵的当前输入电压。该采样电路可以包括模数转换器，该模数转换器的输入端与电荷泵的输入端连接，该模数转换器的输出端可以与终端设备的处理器连接，从而终端设备可以获取电荷泵的当前输入电压。Exemplarily, the current input voltage of the charge pump can be obtained by collecting the voltage at the input terminal of the charge pump in real time through the sampling circuit. The sampling circuit can include an analog-to-digital converter, the input of the analog-to-digital converter is connected to the input of the charge pump, and the output of the analog-to-digital converter can be connected to the processor of the terminal device, so that the terminal device can obtain the charge pump current input voltage.
该步骤S43可以周期性执行，例如每隔200ms～500ms执行一次。This step S43 may be performed periodically, for example, once every 200ms˜500ms.
在该步骤S44中，获取该充电器类型所对应的对应关系。In this step S44, the corresponding relationship corresponding to the charger type is obtained.
该对应关系为电荷泵的输入电压和输入电流的对应关系。这里，电荷泵的输入电压可以为充电器提供给电荷泵的电压。输入电流为充电器提供给电荷泵的电流。在该对应关系中，输入电压和输入电流为负相关关系，也即是，输入电压越大，输入电流越小。The corresponding relationship is the corresponding relationship between the input voltage and the input current of the charge pump. Here, the input voltage of the charge pump may be the voltage provided by the charger to the charge pump. The input current is the current supplied by the charger to the charge pump. In this corresponding relationship, the input voltage and the input current are negatively correlated, that is, the larger the input voltage is, the smaller the input current is.
示例性地，该对应关系可以包括多个电压范围，每个电压范围对应唯一一个输入电流。可选地，随着电压范围的变化，电流值可以等间隔减小，例如，每次减小0.2C或0.1C；也可以不等间隔减小，本公开对此不作限制。Exemplarily, the corresponding relationship may include multiple voltage ranges, and each voltage range corresponds to a unique input current. Optionally, as the voltage range changes, the current value may decrease at equal intervals, for example, decrease by 0.2C or 0.1C each time; it may also decrease at unequal intervals, which is not limited in the present disclosure.
由于电荷泵的输入电压通常为电池电压的2倍，而电池电压在恒流充电阶段的变化范围通常为3.9V～5.5V，则相应地，电荷泵的输入电压的变化范围为7.8V～11V。将输入电压的变化范围划分为多个区间，即前述电压范围，每个区间对应一个输入电流。示例性地，表一显示了一种电荷泵的输入电压和输入电流的对应关系，从表一可以看出，随着输入电压的增大，输入电流逐渐减小。Since the input voltage of the charge pump is usually twice the battery voltage, and the range of the battery voltage during the constant current charging stage is usually 3.9V to 5.5V, correspondingly, the range of the input voltage of the charge pump is 7.8V to 11V . The variation range of the input voltage is divided into multiple intervals, that is, the aforementioned voltage ranges, and each interval corresponds to an input current. Exemplarily, Table 1 shows a corresponding relationship between an input voltage and an input current of a charge pump, and it can be seen from Table 1 that as the input voltage increases, the input current decreases gradually.
表一电荷泵的输入电压和输入电流的对应关系Table 1 Correspondence between the input voltage and input current of the charge pump
需要说明的是，表一中各个区间的端点值可以属于相邻的区间中的任意一个，本公开对此不作限制。It should be noted that the endpoint values of each interval in Table 1 may belong to any one of the adjacent intervals, which is not limited in the present disclosure.
该对应关系可以通过试验获得，只要能够满足提高充电效率，且不超过电池的额定充电功率即可。该对应关系可以预先存储在移动终端中。The corresponding relationship can be obtained through experiments, as long as the charging efficiency can be improved and the rated charging power of the battery is not exceeded. The corresponding relationship may be pre-stored in the mobile terminal.
本公开实施例中，输入电压的不同的范围对应不同的输入电流，且随着充电过程的进行，输入电压的范围以增大的方式变化，而输入电流以减小的方式变化，且在输入电压在同一范围内变化时，输入电流不变，因此，在利用电荷泵充电的过程中，输入电流呈阶梯状递减。这样，可以保证在输入电压较低的情况下，采用较大的充电电流对电池进行充电，而输入电压逐渐升高后，输入电流降低，以防止超过电池的额定充电功率。In the embodiments of the present disclosure, different ranges of the input voltage correspond to different input currents, and as the charging process progresses, the range of the input voltage changes in an increasing manner, while the input current changes in a decreasing manner, and the input When the voltage changes within the same range, the input current does not change. Therefore, in the process of charging with the charge pump, the input current decreases stepwise. In this way, it can be ensured that when the input voltage is low, a larger charging current is used to charge the battery, and after the input voltage gradually increases, the input current decreases to prevent exceeding the rated charging power of the battery.
在一些实施例中，可能存在多个支持提供可变输出电压的充电器类型，不同的充电器类型可以对应不同的对应关系，例如，具有不同的电压区间的数量；又例如，或者电压区间的数量相同，但至少两个区间的端点值不同；再例如，电压区间划分方式相同，但是，同一电压区间对应的输入电流不同。In some embodiments, there may be multiple charger types that support variable output voltages, and different charger types may correspond to different correspondences, for example, having different numbers of voltage intervals; for another example, or the number of voltage intervals The numbers are the same, but the endpoint values of at least two intervals are different; for another example, the voltage intervals are divided in the same way, but the input current corresponding to the same voltage interval is different.
可替代地，也可以至少两个不同的充电器类型对应相同的对应关系。Alternatively, at least two different charger types may correspond to the same corresponding relationship.
在步骤S45中，基于该对应关系，确定当前输入电压所对应的输入电流。In step S45, based on the corresponding relationship, the input current corresponding to the current input voltage is determined.
该步骤S45可以包括：This step S45 may include:
第一步、基于该对应关系，确定当前输入电压所属的电压范围；The first step is to determine the voltage range to which the current input voltage belongs based on the corresponding relationship;
第二步、确定该电压范围对应的输入电流。The second step is to determine the input current corresponding to the voltage range.
在步骤S46中，根据确定出的输入电流，控制电荷泵的输入电流。In step S46, the input current of the charge pump is controlled according to the determined input current.
该步骤S46可以包括：This step S46 may include:
第一步、比较电荷泵的当前输入电流和该电压范围对应的输入电流；The first step is to compare the current input current of the charge pump with the input current corresponding to the voltage range;
第二步、若电荷泵的当前输入电流和该电压范围对应的输入电流不一致，则调整当前的输入电流。若电荷泵的当前输入电流和该电压范围对应的输入电流一致，则保持当前的输入电流。In the second step, if the current input current of the charge pump is inconsistent with the input current corresponding to the voltage range, adjust the current input current. If the current input current of the charge pump is consistent with the input current corresponding to the voltage range, the current input current is maintained.
示例性地，在该步骤S46中，调整当前的输入电流可以采用以下方式：当确定出的输入电流与电荷泵的当前输入电流不一致时，向充电器发送电流调整请求，该电流调整请求用于请求充电器将向电荷泵提供的输入电流调整为该确定出的输入电流。Exemplarily, in this step S46, the following manner may be adopted for adjusting the current input current: when the determined input current is inconsistent with the current input current of the charge pump, a current adjustment request is sent to the charger, and the current adjustment request is used for The charger is requested to adjust the input current provided to the charge pump to the determined input current.
相应地，保持当前的输入电流可以采用以下方式：当确定出的输入电流与电荷泵的当前输入电流一致时，不向充电器发送电流调整请求，则充电器不会调整向电荷泵提供的输入电流。Correspondingly, the following method can be used to maintain the current input current: when the determined input current is consistent with the current input current of the charge pump, no current adjustment request is sent to the charger, and the charger will not adjust the input provided to the charge pump current.
例如，在电荷泵刚开始工作的时候，输入电压为7.8V～9V，对应的输入电流为1.5C，在电池充电一段时间之后，电荷泵的输入电压变为临界值9V，假设9V属于第二个电压范围9V～9.2V，则确定出的电压范围对应的输入电流为1.2C，此时，当前输入电流为1.5C，与确定出的电压范围对应的输入电流不一致，则需要将输入电流调整至1.2C，即调整至该电压范围对应的输入电流。For example, when the charge pump starts to work, the input voltage is 7.8V ~ 9V, and the corresponding input current is 1.5C. After the battery is charged for a period of time, the input voltage of the charge pump becomes a critical value of 9V, assuming that 9V belongs to the second A voltage range of 9V to 9.2V, the input current corresponding to the determined voltage range is 1.2C. At this time, the current input current is 1.5C, which is inconsistent with the input current corresponding to the determined voltage range, and the input current needs to be adjusted. To 1.2C, that is, adjust to the input current corresponding to the voltage range.
继续检测电荷泵的输入电压，若检测到的电荷泵的输入电压为9.1V，仍然属于第二个电压范围9V～9.2V，则确定出的电压范围对应的输入电流为1.2C，此时，当前输入电流为1.2C，与确定出的电压范围对应的输入电流一致，则无需调整电荷泵的输入电流。Continue to detect the input voltage of the charge pump. If the detected input voltage of the charge pump is 9.1V, which still belongs to the second voltage range of 9V to 9.2V, the input current corresponding to the determined voltage range is 1.2C. At this time, The current input current is 1.2C, which is consistent with the input current corresponding to the determined voltage range, so there is no need to adjust the input current of the charge pump.
通过该方式，可以对电流进行分段控制，当充电电压在第一电压范围变化时，电荷泵的输入电流为确定出的输入电流值，若电池的电压随着充电过程的进行而变大时，充电电压上升到第二电压范围，则将电荷泵的输入电流减小到该第二区间对应的输入电流，由于电荷泵提供给电池的电流等于电荷泵的输入电流，而电荷泵提供给电池的电压为电荷泵的输入电压的二分之一，因此，通过这种方式，可以减小电荷泵的输出功率，避免电荷泵输出至电池的输出功率超过电池的额定充电功率。同时，在电荷泵提供给电池的电压较小时，可以采用较大的电流为电池充电，因此，可以获得较高的充电效率。In this way, the current can be controlled in sections. When the charging voltage changes in the first voltage range, the input current of the charge pump is the determined input current value. If the battery voltage increases with the charging process , the charging voltage rises to the second voltage range, then the input current of the charge pump is reduced to the input current corresponding to the second range, because the current provided by the charge pump to the battery is equal to the input current of the charge pump, and the charge pump provides the battery The voltage of the charge pump is half of the input voltage of the charge pump. Therefore, in this way, the output power of the charge pump can be reduced to prevent the output power of the charge pump from exceeding the rated charging power of the battery. At the same time, when the voltage provided by the charge pump to the battery is relatively small, a relatively large current can be used to charge the battery, and thus a relatively high charging efficiency can be obtained.
可选地，若终端设备采用有线方式充电，则可以通过充电线，例如USB数据线发送该电流调整请求；若终端设备采用无线方式充电，则可以在终端设备和充电器上分别配置无线通信模块，利用无线通信模块通信以发送该电流调整请求。Optionally, if the terminal device is charged in a wired manner, the current adjustment request can be sent through a charging cable, such as a USB data cable; if the terminal device is charged in a wireless manner, a wireless communication module can be configured on the terminal device and the charger respectively , using the wireless communication module to communicate to send the current adjustment request.
示例性地，无线通信模块可以为蓝牙通信模块或者近场通信(Near FieldCommunication，NFC)模块等。Exemplarily, the wireless communication module may be a Bluetooth communication module or a near field communication (Near Field Communication, NFC) module or the like.
在一些实施例中，该电流调整请求可以携带确定出的输入电流。在另一些实施例中，该电流调整请求可以不携带确定出的输入电流，充电器中存储有前述对应关系，可以根据充电器的当前输出电压和该对应关系，确定出目标输入电流，并按照该目标输入电流向电荷泵提供输入电流，即将向电荷泵提供的输入电流调整为该目标输入电流。In some embodiments, the current adjustment request may carry the determined input current. In other embodiments, the current adjustment request may not carry the determined input current, the charger stores the aforementioned corresponding relationship, and the target input current may be determined according to the current output voltage of the charger and the corresponding relationship, and according to The target input current provides an input current to the charge pump, that is, the input current provided to the charge pump is adjusted to the target input current.
在本公开实施例中，在采用电荷泵对电池的充电过程中，获取电荷泵的当前输入电压；获取电荷泵的输入电压与输入电流的对应关系；并基于该对应关系，确定当前输入电压对应的输入电流，由于在该对应关系中，输入电压与输入电流为负相关关系，所以随着电荷泵的输入电压的增大，确定出的电荷泵的输入电流逐渐减小。在这种情况下，根据确定出的所述输入电流，控制电荷泵的输入电流，可以达到随着输入电压的增大而减小电荷泵的输入电流的目的。由于电荷泵的输出功率等于电荷泵的输入电压的二分之一乘以电荷泵的输入电流，所以本公开实施例中的电荷泵的输入电流的调整方式可以减缓电荷泵的输出功率的上升趋势，避免电荷泵的输出功率超过电池的额定充电功率。In the embodiment of the present disclosure, in the process of charging the battery by using the charge pump, the current input voltage of the charge pump is obtained; the corresponding relationship between the input voltage and the input current of the charge pump is obtained; and based on the corresponding relationship, the current input voltage corresponding to The input current of the input current, because in this corresponding relationship, the input voltage and the input current are negatively correlated, so as the input voltage of the charge pump increases, the determined input current of the charge pump decreases gradually. In this case, the input current of the charge pump is controlled according to the determined input current, so as to reduce the input current of the charge pump as the input voltage increases. Since the output power of the charge pump is equal to one-half of the input voltage of the charge pump multiplied by the input current of the charge pump, the adjustment method of the input current of the charge pump in the embodiments of the present disclosure can slow down the rising trend of the output power of the charge pump , to avoid the output power of the charge pump exceeding the rated charging power of the battery.
