具体实施方式DETAILED DESCRIPTION
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。以下示例性所描述的实施例并不代表与本公开相一致的所有实施例。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例子。Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described below by way of example do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.
相关技术中为各电芯设置一个电量计的方案，随着电池中电芯数量的增加，会增加电池的体积或者电子设备的体积，还会增加电子设备的成本。In the related art, a solution of providing a fuel meter for each battery cell will increase the volume of the battery or the electronic device as the number of battery cells in the battery increases, and will also increase the cost of the electronic device.
为解决上述技术问题，本公开实施例提供了一种获取电池电量的方法，其中电池包括至少两个电芯和一个电量计，该电池可以应用于如智能手机、平板电脑、个人计算机、服务器等电子设备。该方法可以适用于电量计，其发明构思在于，通过一个电量计利用各电芯的充放电电流来获取电池的电量，这样可以减少电池中电量计的数量，从而减小电池的体积，降低生产成本。In order to solve the above technical problems, the embodiment of the present disclosure provides a method for obtaining the power of a battery, wherein the battery includes at least two cells and a fuel gauge, and the battery can be applied to electronic devices such as smart phones, tablet computers, personal computers, servers, etc. The method can be applied to a fuel gauge, and the inventive concept is that the power of the battery is obtained by using the charge and discharge current of each cell through a fuel gauge, which can reduce the number of fuel gauges in the battery, thereby reducing the volume of the battery and reducing the production cost.
图1是根据一示例性实施例示出的一种获取电池电量的方法的流程图，参见图1，一种获取电池电量的方法，包括步骤11～步骤13，其中：FIG. 1 is a flow chart of a method for obtaining battery power according to an exemplary embodiment. Referring to FIG. 1 , a method for obtaining battery power includes steps 11 to 13, wherein:
在步骤11中，当所述至少两个电芯的连接状态完成切换后，获取各电芯在当前连接状态下的充放电电流。In step 11, after the connection status of the at least two battery cells is switched, the charge and discharge current of each battery cell in the current connection status is obtained.
本实施例中，电池中的至少两个电芯包括切换电路，该切换电路在接收到控制信号后，可以将至少两个电芯的连接状态切换到串联状态或者并联状态，即所有的电芯串联或者所述的电芯并联。其中，控制信号可以由电量计发送，或者由设置有电池的电子设备的处理器发送，在此不作限定。In this embodiment, at least two cells in the battery include a switching circuit, which, after receiving a control signal, can switch the connection state of the at least two cells to a series state or a parallel state, that is, all cells are connected in series or the cells are connected in parallel. The control signal can be sent by a power meter or by a processor of an electronic device equipped with a battery, which is not limited here.
需要说明的是，当电芯较多时，其连接状态还可以包括串联和并联相混合的状态，此情况下可以将串联的电芯和并联的电芯分开计算，即连接状态又可以拆分为串联状态和并联状态，为方便理解，后续以串联状态和并联状态描述各实施例。It should be noted that when there are many battery cells, their connection status may also include a mixed state of series and parallel connection. In this case, the battery cells in series and the battery cells in parallel may be calculated separately, that is, the connection status may be divided into a series state and a parallel state. For ease of understanding, each embodiment will be described in terms of the series state and the parallel state in the following.
本实施例中，电量计可以获取控制信号，该控制信号可以来自自身、处理器或者电池管理芯片，在此不作限定。在接收到控制信号后，电量计确定电芯的连接状态。In this embodiment, the fuel gauge can obtain a control signal, and the control signal can come from the fuel gauge itself, a processor, or a battery management chip, which is not limited here. After receiving the control signal, the fuel gauge determines the connection status of the battery cell.
另一实施例中，电量计也可以不用获取控制信号，此情况下，电量计可以按照设定周期或者实时获取各电芯的端电压，若各电芯的端电压相等或者相近(电压之差在预设范围内，如0.5V)，则说明各电芯的连接状态为并联状态；若任意相邻两个电芯中的一个电芯的端电压，大约是另一个电芯的端电压的2倍或者相差较大(例如3-4V)，则说明各电芯的连接状态为串联状态。In another embodiment, the fuel meter does not need to obtain the control signal. In this case, the fuel meter can obtain the terminal voltage of each battery cell according to a set period or in real time. If the terminal voltages of each battery cell are equal or similar (the voltage difference is within a preset range, such as 0.5V), it means that the connection state of each battery cell is in parallel; if the terminal voltage of one battery cell between any two adjacent battery cells is approximately twice the terminal voltage of the other battery cell or the difference is large (for example, 3-4V), it means that the connection state of each battery cell is in series.
本实施例中，电量计在确定连接状态后，可以获取当前连接状态下的充放电电流。例如，在连接状态为图2(a)所示的串联状态时，采集任一电芯的电流作为各电芯的充放电电流，如采集精密电阻1的电流作为电芯1和电芯2充放电电流；又如，在连接状态为图2(b)所示的并联状态时，采集各电芯的电流作为各自的充放电电流，如采集精密电阻1的电流作为电芯1的充放电电流，采集精密电阻2的电流作为电芯2的充放电电流。In this embodiment, after determining the connection state, the fuel gauge can obtain the charge and discharge current in the current connection state. For example, when the connection state is the series state shown in Figure 2 (a), the current of any battery cell is collected as the charge and discharge current of each battery cell, such as collecting the current of precision resistor 1 as the charge and discharge current of battery cell 1 and battery cell 2; for another example, when the connection state is the parallel state shown in Figure 2 (b), the current of each battery cell is collected as the respective charge and discharge current, such as collecting the current of precision resistor 1 as the charge and discharge current of battery cell 1, and collecting the current of precision resistor 2 as the charge and discharge current of battery cell 2.
在步骤12中，根据所述充放电电流获取各电芯的电量变化量。In step 12, the amount of charge change of each battery cell is obtained according to the charge and discharge current.
本实施例中，电量计可以根据充放电电流获取可各电芯的电量变化量。以其中一个电芯为例，电量计可以根据本次获取充放电电流和前一次获取充放电电流的时间时间，对充放电电流进行积分，从而得到该电芯的电量变化量。In this embodiment, the fuel gauge can obtain the amount of change in the amount of power of each battery cell according to the charge and discharge current. Taking one of the batteries as an example, the fuel gauge can integrate the charge and discharge current according to the time of obtaining the charge and discharge current this time and the time of obtaining the charge and discharge current last time, so as to obtain the amount of change in the amount of power of the battery cell.
在步骤13中，根据各电芯的电量变化量获取所述电池的电量。In step 13, the power of the battery is obtained according to the change in power of each battery cell.
本实施例中，电量计可以从存储器获取各电芯在前一次检测时所得到的电量，以下称之为初始电量；然后，电量计可以获取各电芯的初始电量与电量变化量，得到各电芯在本次检测过程所得到的实际电量。需要说明的是，在获取各电芯的实际电量时，若电池处于充电状态，则实际电量等于初始电量与电量变化量之和；若电池处于放电状态，则实际电量等于初始电量与电量变化量之差。其中，充电状态或者放电状态或者根据充放电电流是流入电池还是流出电池获得。之后，电量计可以获取各电芯的电量之和，得到电池的电量；或者，电量计可以获取各电芯的电量与最大电量的电量比例，将电量比例的平均值作为电池的电容，或者将电芯中最小的电量比例作为电池的电量。这样，本实施例中采用一个电量计即可获取到电池的电量，有利于降低电池的体积或者电子设备的体积，降低成本。In this embodiment, the fuel gauge can obtain the power obtained by each battery cell in the previous detection from the memory, which is referred to as the initial power; then, the fuel gauge can obtain the initial power and power change of each battery cell to obtain the actual power obtained by each battery cell in this detection process. It should be noted that when obtaining the actual power of each battery cell, if the battery is in a charging state, the actual power is equal to the sum of the initial power and the power change; if the battery is in a discharging state, the actual power is equal to the difference between the initial power and the power change. Among them, the charging state or the discharging state is obtained according to whether the charging and discharging current flows into the battery or flows out of the battery. Afterwards, the fuel gauge can obtain the sum of the power of each battery cell to obtain the power of the battery; or, the fuel gauge can obtain the power ratio of the power of each battery cell to the maximum power, and use the average value of the power ratio as the capacitance of the battery, or use the smallest power ratio in the battery cell as the power of the battery. In this way, in this embodiment, a fuel gauge can be used to obtain the power of the battery, which is conducive to reducing the volume of the battery or the volume of the electronic device and reducing costs.
考虑到电池在充电和/或放电过程中，以及电池的使用环境发生变化(如温度变化)，各电芯的内部电阻会动态变化，导致获取的电池的电量存在一定的误差。随着时间的积累，累积误差会越来越大。因此，在一实施例中，电量计可以对电池的电量进行校正。在对电量校正之前，电量计可以先对电池的内部电阻进行校正，参见图3，包括步骤31～步骤33：Considering that the internal resistance of each battery cell will change dynamically during the charging and/or discharging process of the battery, as well as changes in the battery's use environment (such as temperature changes), the obtained battery power will have a certain error. As time accumulates, the cumulative error will become larger and larger. Therefore, in one embodiment, the fuel meter can calibrate the battery power. Before calibrating the power, the fuel meter can first calibrate the internal resistance of the battery, see Figure 3, including steps 31 to 33:
在步骤31中，在电芯的连接状态切换为并联状态的预设时间段(如1-50ms，可调整)之内，电量计可以获取各电芯的充放电电流、检测电压、初始内部电阻、连接状态切换前后引起的电压变化量和预测充放电电流。其中，检测电压是指从串联状态切换到并联状态之后的第一次所能检测到的电压。初始内部电阻是指上一次所获取的内部电阻。连接状态切换前后引起的电压变化量是指切换之前串联状态下所能检测到的最后一次的电压U1-1和切换之后并联状态下所能检测到的第一次的电压U1-2之差，例如电芯1的电压变化量为U1-1-U1-2。预测充放电电流基于电芯的检测电压和初始内部电阻获得。在步骤32中，电量计可以获取各电芯的充放电电流和预测充放电电流之差，得到电流变化量。例如电芯1的预测充放电电流为I1-1，充放电电流为I1-2，则电流变化量为I1-1-I1-2。在步骤33中，电量计可以根据各电芯的电压变化量和电流变化量获得各电芯的实际内部电阻。例如，电芯1的实际内部电阻R1’＝(U1-1-U1-2)/(I1-1-I1-2)。In step 31, within a preset time period (such as 1-50ms, adjustable) when the connection state of the battery cell is switched to the parallel state, the fuel gauge can obtain the charge and discharge current, detection voltage, initial internal resistance, voltage change caused before and after the connection state switching, and predicted charge and discharge current of each battery cell. Among them, the detection voltage refers to the voltage that can be detected for the first time after switching from the series state to the parallel state. The initial internal resistance refers to the internal resistance obtained last time. The voltage change caused before and after the connection state switching refers to the difference between the last voltage U1-1 that can be detected in the series state before the switching and the first voltage U1-2 that can be detected in the parallel state after the switching, for example, the voltage change of battery cell 1 is U 1-1 -U 1-2 . The predicted charge and discharge current is obtained based on the detection voltage and initial internal resistance of the battery cell. In step 32, the fuel gauge can obtain the difference between the charge and discharge current of each battery cell and the predicted charge and discharge current to obtain the current change. For example, the predicted charge and discharge current of cell 1 is I 1-1 , and the charge and discharge current is I 1-2 , then the current change is I 1-1 -I 1-2 . In step 33 , the fuel gauge can obtain the actual internal resistance of each cell according to the voltage change and current change of each cell. For example, the actual internal resistance R1' of cell 1 is R1'=(U 1-1 -U 1-2 )/(I 1-1 -I 1-2 ).
需要说明的是，本实施例中，实际内部电阻可以按照设定周期(例如取值范围在5-10分钟之间，可调整)对各电芯的内部电阻进行调整；还可以在从待机(电芯电流约几-数十毫安级别)到使用(电芯电流约为数十到数百毫安级别)，即电芯输出电流突变较大的场景，若电芯的端电压发生变化，如从4.25V下降到4V，此时需要对电芯的内部电阻进行校正。技术人员可以根据具体场景设置合适的校正时间或者校正场景，相应方案落入本公开的保护范围。It should be noted that in this embodiment, the actual internal resistance can be adjusted according to a set period (for example, the value range is between 5-10 minutes, which can be adjusted) for the internal resistance of each battery cell; it can also be adjusted from standby (battery cell current is about several to tens of milliamperes) to use (battery cell current is about tens to hundreds of milliamperes), that is, when the battery cell output current changes greatly, if the terminal voltage of the battery cell changes, such as from 4.25V to 4V, the internal resistance of the battery cell needs to be corrected. The technician can set the appropriate correction time or correction scenario according to the specific scenario, and the corresponding scheme falls within the protection scope of the present disclosure.
需要说明的是，本实施例中，电量计可以将获取的实际内部电阻存储到指定的存储区域。在一示例中，电量计还与上一次校正的内部电阻进行对比，当本次的实际内部电阻与上一次的内部电阻的差值在预设的差值范围(如电阻值变化小于10％)内时，确定本次的实际内部电阻为有效值，可以存储到指定的存储区域，若超过差值范围，则确定实际内部电阻为无效值，直接丢弃。It should be noted that, in this embodiment, the power meter can store the actual internal resistance obtained in a designated storage area. In one example, the power meter also compares the internal resistance with the internal resistance calibrated last time. When the difference between the actual internal resistance this time and the internal resistance last time is within a preset difference range (such as a resistance value change of less than 10%), the actual internal resistance this time is determined to be a valid value and can be stored in the designated storage area. If it exceeds the difference range, the actual internal resistance is determined to be an invalid value and is directly discarded.
在获取到各电芯的实际内部电阻之后，可以再对电池的电量进行校正，参见图4，包括步骤41～步骤43：After obtaining the actual internal resistance of each battery cell, the battery power can be calibrated, as shown in FIG4 , including steps 41 to 43:
在步骤41中，电量计可以获取到实际内部电阻和检测电压。需要说明的是，实际内部电阻可以为本次电量校正过程所获取的电阻，还可以是之前获取的内部电阻(即可以理解为初始内部电阻)。本实施例中以前者为例进行说明。在步骤42中，电量计可以根据各电芯的实际内部电阻、充放电电流和检测电压获取各电芯的实际电压。例如，电芯1的实际电压U1’＝U1+I*R1’，其中，U1是指电芯1的检测电压，即实际检测到的电压，I是指电芯1的充放电电流，R1’是指电芯1的实际内部电阻。在步骤43中，基于图5所示的预设的电压和电量的对应曲线，电量计可以根据各电芯的实际电压获得该电芯的电量。例如，当一个电芯的电压为3.8V时，其电量采用比例表示可以是40％。然后，电量计可以根据各电芯的电量来确定电池的电量。以电量采用比例为例，在充电过程中，可以将电量比例最大的电芯的比例作为电池的电量；在放电过程中，可以将电量比例最小的电芯的比例作为电池的电量。In step 41, the fuel gauge can obtain the actual internal resistance and the detection voltage. It should be noted that the actual internal resistance can be the resistance obtained in this power calibration process, or it can be the internal resistance obtained previously (that is, it can be understood as the initial internal resistance). In this embodiment, the former is used as an example for explanation. In step 42, the fuel gauge can obtain the actual voltage of each battery cell according to the actual internal resistance, charge and discharge current and detection voltage of each battery cell. For example, the actual voltage U1'=U1+I*R1' of battery cell 1, wherein U1 refers to the detection voltage of battery cell 1, that is, the actual detected voltage, I refers to the charge and discharge current of battery cell 1, and R1' refers to the actual internal resistance of battery cell 1. In step 43, based on the corresponding curve of the preset voltage and power shown in FIG5, the fuel gauge can obtain the power of each battery cell according to the actual voltage of the battery cell. For example, when the voltage of a battery cell is 3.8V, the proportion of its power can be 40%. Then, the fuel gauge can determine the power of the battery according to the power of each battery cell. Taking the power usage ratio as an example, during the charging process, the ratio of the battery cell with the largest power ratio can be used as the battery power; during the discharging process, the ratio of the battery cell with the smallest power ratio can be used as the battery power.
可理解的的是，本实施例中通过对各电芯的内部电阻进行校正，可以使电芯的内部电阻与连接状态或者使用环境更匹配，能够反映出电芯的真实内阻。进而，使用校正后的内部电阻来对电池的电量进行校正，可以使电池的电量更准确，有利于降低累积误差。It is understandable that in this embodiment, by correcting the internal resistance of each battery cell, the internal resistance of the battery cell can be more matched with the connection state or the use environment, and can reflect the real internal resistance of the battery cell. Furthermore, using the corrected internal resistance to correct the battery power can make the battery power more accurate, which is conducive to reducing the cumulative error.
