When the charging box is charging the battery, the value actually collected by the AD is falsely higher than the actual voltage value. When the battery is discharging, the voltage value actually collected by the AD is falsely lower than the true value. This is because of the internal resistance and contact impedance of the battery. The existence of , thus resulting in inaccurate display of the power of electronic products.

It should be noted that although a logical sequence is shown in the flowchart, in some cases, the shown or described steps.
在本实施例中，该电池电量补偿方法包括：In this embodiment, the battery power compensation method includes:
步骤S100，在所述设备当前进行充电操作时，基于所述设备的电压充电采集模块采集电池当前的初始充电电压；Step S100, when the device is currently performing a charging operation, collect the current initial charging voltage of the battery based on the voltage charging acquisition module of the device;
在本实施例中，微控制单元(Microcontroller Unit；MCU)，又称单片微型计算机(Single Chip Microcomputer)或者单片机，是把中央处理器(Central Process Unit；CPU)的频率与规格做适当缩减，并将内存(memory)、计数器(Timer)、USB、A/D转换、UART、PLC、DMA等周边接口，甚至LCD驱动电路都整合在单一芯片上，形成芯片级的计算机，为不同的应用场合做不同组合控制。诸如手机、PC外围、遥控器，至汽车电子、工业上的步进马达、机器手臂的控制等，都可见到MCU的身影。在现有技术中，采用为了节约成本，可以直接使用MCU采集电池的电压，然后把采集的电压转化为电量。In this embodiment, a Microcontroller Unit (MCU), also known as a Single Chip Microcomputer (Single Chip Microcomputer) or a single-chip microcomputer, appropriately reduces the frequency and specifications of a central processing unit (Central Process Unit; CPU). Integrate peripheral interfaces such as memory, counter (Timer), USB, A/D conversion, UART, PLC, DMA, and even LCD driver circuits on a single chip to form a chip-level computer for different applications. Do different combinations of controls. Such as mobile phones, PC peripherals, remote controls, automotive electronics, industrial stepper motors, robotic arm control, etc., MCU can be seen. In the prior art, in order to save costs, the MCU can be directly used to collect the voltage of the battery, and then the collected voltage can be converted into electricity.
如前所述，使用MCU的AD模块采集电池的电压，根据电池的电压通过查表方式，计算出对应的电量，相当于电压型电量计的算法放到MCU里面。充电盒对电池进行充电的时候，AD实际采集的值比真实的值虚高，在电池放电的时候，AD实际采集的值比真实的值虚低，因而导致电子产品的电量显示 不准确。本申请提出的电池电量补偿方法，通过利用充电补偿电流对充电电压进行补充，得到更准确的电压，进而能较准确的显示电量，使用户能及时了解充电情况或更好的使用。As mentioned above, the AD module of the MCU is used to collect the voltage of the battery, and according to the voltage of the battery, the corresponding power is calculated by looking up the table, which is equivalent to the algorithm of the voltage-type fuel gauge being placed in the MCU. When the charging box is charging the battery, the value actually collected by the AD is falsely higher than the real value, and when the battery is discharged, the value actually collected by the AD is falsely lower than the true value, which results in an inaccurate display of the power of the electronic product. The battery power compensation method proposed in the present application obtains a more accurate voltage by using the charging compensation current to supplement the charging voltage, and then can display the power more accurately, so that the user can know the charging situation in time or use it better.
具体地，当设备接收到充电指令时，开始启动充电操作，该充电指令一般是由设备的电池充电接口触发，即当检测到电池充电接口有充电电压时，则触发充电指令，设备进入充电状态。当设备当前进行充电操作时，利用设备内置的微控制单元MCU的AD模块采集电池的电压，作为电池当前的初始充电电压。Specifically, when the device receives a charging command, it starts the charging operation. The charging command is generally triggered by the battery charging interface of the device. That is, when it is detected that the battery charging interface has a charging voltage, the charging command is triggered and the device enters the charging state. . When the device is currently performing a charging operation, the AD module of the built-in microcontroller unit MCU is used to collect the voltage of the battery as the current initial charging voltage of the battery.
步骤S200，确定电池当前的充电阶段，并基于所述当前充电阶段获取充电补偿电流；Step S200, determining the current charging stage of the battery, and obtaining a charging compensation current based on the current charging stage;
在本实施例中，设备进入充电状态，根据电池当前的充电阶段获取充电补偿电流，不同充电阶段对应的充电补偿电流。该充电补偿电流可以在电流对照表中查找，根据当前充电阶段在电流对照表中获取对应的充电补偿电流。需要说明的是，电池当前的充电阶段是可以通过设备的MCU读取。In this embodiment, the device enters the charging state, and obtains the charging compensation current according to the current charging stage of the battery, and the charging compensation current corresponding to different charging stages. The charging compensation current can be searched in the current comparison table, and the corresponding charging compensation current is obtained in the current comparison table according to the current charging stage. It should be noted that the current charging stage of the battery can be read by the MCU of the device.
具体地，涓流阶段是用来对完全放电的电池单元进行预充(恢复性充电)；预充恒流阶段和快充恒流阶段都属于恒流充电，当电池电压上升到涓流充电阈值以上时，提高充电电流进行恒流充电，恒流充电时的电流并不要求十分精确，准恒定电流也可以；恒压充电，以固定电压进行充电，当电池电压上升到预设电压值时，如4.2V，恒流充电结束，开始恒压充电阶段；充电终止阶段，因为不建议对锂离子电池连续涓流充电，连续涓流充电会导致金属锂出现极板电镀效应，这会使电池不稳定，并且有可能导致突然的自动快速解体，有两种典型的充电终止方法：采用最小充电电流判断或采用定时器(或者两者的结合)，最小电流法监视恒压充电阶段的充电电流，并在充电电流减小到阈值范围时终止充电；第二种方法从恒压充电阶段开始时计时，持续充电预设时长后终止充电过程。Specifically, the trickle phase is used to precharge the fully discharged battery cells (recovery charging); both the precharge constant current phase and the fast charge constant current phase belong to constant current charging. When the battery voltage rises to the trickle charging threshold In the above case, increase the charging current for constant current charging. The current during constant current charging is not required to be very accurate, and a quasi-constant current can also be used; for constant voltage charging, charging is performed at a fixed voltage. When the battery voltage rises to the preset voltage value, For example, at 4.2V, the constant current charging ends, and the constant voltage charging stage begins; in the charging termination stage, continuous trickle charging is not recommended for lithium-ion batteries. Continuous trickle charging will cause the metal lithium to have a plate plating effect, which will make the battery ineffective. It is stable and may cause sudden automatic rapid disintegration. There are two typical charging termination methods: using the minimum charging current judgment or using a timer (or a combination of the two), the minimum current method to monitor the charging current in the constant voltage charging stage, And the charging is terminated when the charging current is reduced to the threshold range; the second method starts timing from the constant voltage charging stage, and terminates the charging process after continuing the charging for a preset period of time.
步骤S300，基于所述充电补偿电流对初始充电电压进行补偿，得到当前充电操作对应的电池电量。Step S300: Compensate the initial charging voltage based on the charging compensation current to obtain the battery power corresponding to the current charging operation.
具体地，步骤S300包括：Specifically, step S300 includes:
步骤S310，基于所述充电补偿电流计算得到电池当前补偿后的充电电压；Step S310, calculating the current compensated charging voltage of the battery based on the charging compensation current;
具体地，步骤S310包括：Specifically, step S310 includes:
步骤S311，获取所述充电补偿电流对应的电阻值，并将所述充电补偿电 流与所述电阻值相乘得到充电补偿电压；Step S311, obtaining the resistance value corresponding to the charging compensation current, and multiplying the charging compensation current by the resistance value to obtain a charging compensation voltage;
步骤S312，将所述电池当前的初始充电电压与所述充电补偿电压的差值作为所述补偿后的充电电压。Step S312, taking the difference between the current initial charging voltage of the battery and the charging compensation voltage as the charging voltage after compensation.
在本实施例中，当电池在产品主板上工作时，由于电池内阻以及接触阻抗的存在，会使得AD采集电池的电压在充电和放电的时候存在虚高虚低的现象，因此针对这种现象对电池的电压进行补偿。In this embodiment, when the battery is working on the main board of the product, due to the existence of the internal resistance of the battery and the contact impedance, the voltage of the AD-collected battery will be falsely high and falsely low during charging and discharging. The phenomenon compensates for the voltage of the battery.
具体地，首先根据充电补偿电流计算得到电池当前补偿后的充电电压，即获取充电补偿电流对应的电阻值，并将充电补偿电流与所述电阻值相乘得到充电补偿电压，将电池当前的初始充电电压与充电补偿电压的差值作为所述补偿后的充电电压。电池设置在设备的主板上，电子产品出厂时，电池内阻以及接触阻抗是已知的，电池内阻与接触阻抗的总阻值为充电补偿电流对应的电阻值，将充电补偿电流与电阻值相乘得到充电补偿电压。电池在充电时，AD实际采集的电压值比真实的值虚高，因此，需要将电池当前的充电电压与补偿电压进行相减，得到的差值为补偿后的充电电压，即接近电池真实的电压。Specifically, firstly, the current compensated charging voltage of the battery is obtained according to the charging compensation current, that is, the resistance value corresponding to the charging compensation current is obtained, and the charging compensation voltage is obtained by multiplying the charging compensation current by the resistance value. The difference between the charging voltage and the charging compensation voltage is used as the compensated charging voltage. The battery is set on the main board of the device. When the electronic product leaves the factory, the internal resistance of the battery and the contact impedance are known. The total resistance value of the internal resistance of the battery and the contact impedance is the resistance value corresponding to the charging compensation current. Multiply to get the charge compensation voltage. When the battery is charging, the voltage value actually collected by AD is falsely higher than the real value. Therefore, it is necessary to subtract the current charging voltage of the battery from the compensation voltage, and the difference obtained is the charging voltage after compensation, which is close to the real value of the battery. Voltage.
步骤S320，利用预设的充电曲线将所述充电电压转换为电池电量。Step S320, using a preset charging curve to convert the charging voltage into battery power.
在本实施例中，当利用充电补偿电流以及电阻值计算得到电池当前补偿后的充电电压后，进而电池当前的初始充电电压与充电补偿电压的差值作为所述补偿后的充电电压。电压与电量存在对应关系，根据预设的充电曲线将充电电压转换为电池电量，其中预设的充电曲线就是电压与电量的对应关系曲线。例如，电池额定电压为4.2V，充电曲线用成对的电压、电量表示，(4.2V，100％)，(4.1V，95％)，(4.0V，95％)……如果当前补偿后的充电电压为4.0V，则根据充电曲线得到当前的电池电量为95％。In this embodiment, after the current compensated charging voltage of the battery is calculated by using the charging compensation current and the resistance value, the difference between the current initial charging voltage of the battery and the charging compensation voltage is used as the compensated charging voltage. There is a corresponding relationship between voltage and power, and the charging voltage is converted into battery power according to a preset charging curve, where the preset charging curve is the corresponding curve between voltage and power. For example, the rated voltage of the battery is 4.2V, and the charging curve is expressed by pairs of voltage and power, (4.2V, 100%), (4.1V, 95%), (4.0V, 95%)... If the current compensation If the charging voltage is 4.0V, the current battery capacity is 95% according to the charging curve.
进一步地，在一实施例中，所述步骤S100之前包括：Further, in an embodiment, before the step S100, it includes:
步骤S400，获取不同充电阶段对应的预设电流；Step S400, obtaining preset currents corresponding to different charging stages;
在本实施例中，充电阶段包括：涓流阶段、预充恒流阶段、快充恒流阶段和恒压阶段、充电终止阶段，每个阶段对应的电流是不同的。充电阶段包括：涓流阶段、预充恒流阶段、快充恒流阶段和恒压阶段、充电终止阶段，其中，涓流阶段、预充恒流阶段、快充恒流阶段的电流是恒定的，并依次增大，涓流阶段的电流非常小，具体的电流值大小根据电池容量的实际情况， 以及实验数据确定。In this embodiment, the charging stage includes: a trickle stage, a precharge constant current stage, a fast charge constant current stage, a constant voltage stage, and a charging termination stage, and the current corresponding to each stage is different. The charging stage includes: a trickle stage, a precharge constant current stage, a fast charge constant current stage, a constant voltage stage, and a charge termination stage, wherein the current in the trickle flow stage, the precharge constant current stage, and the fast charge constant current stage is constant , and increase sequentially, the current in the trickle phase is very small, and the specific current value is determined according to the actual situation of the battery capacity and experimental data.
进一步地，当充电阶段为恒压阶段时，步骤S400包括：Further, when the charging stage is the constant voltage stage, step S400 includes:
步骤S410，获取恒压阶段对应的多个预设电流；Step S410, acquiring multiple preset currents corresponding to the constant voltage stage;
步骤S420，按照进入恒压阶段的充电时长将多个预设电流进行分组，并计算各个分组对应的平均电流，将所述平均电流作为子阶段对应的预设电流。Step S420, grouping a plurality of preset currents according to the charging duration in the constant voltage stage, calculating the average current corresponding to each group, and using the average current as the preset current corresponding to the sub-stage.
在本实施例中，恒压阶段是指电压在充电时间里保持恒定的数值，随着电池端电压的逐渐升高，电流逐渐减小，恒压阶段前期的电流往往会很大，随着端电压的逐渐上升，电流慢慢减小。当充电器电压和电池两端的稳定电压接近时，电流接近于零。In this embodiment, the constant voltage stage means that the voltage keeps a constant value during the charging time. As the battery terminal voltage gradually increases, the current gradually decreases, and the current in the early stage of the constant voltage stage tends to be very large. The voltage gradually rises and the current gradually decreases. When the charger voltage and the regulated voltage across the battery are close, the current is close to zero.
进一步，可以将恒压阶段按照时间分成若干时间段，记为子阶段，然后求每个时间段内的平均电流，即子阶段对应的电流。利用恒压阶段的历史数据，将在同一个时间段的电流分为一组，然后分别求每个时间段内的平均电流。Further, the constant voltage stage can be divided into several time periods according to time, which are recorded as sub-stages, and then the average current in each time period, that is, the current corresponding to the sub-stages, can be calculated. Using the historical data of the constant voltage stage, the currents in the same time period are grouped into a group, and then the average current in each time period is calculated separately.
步骤S500，基于所述充电阶段与所述预设电流的对应关系，生成电流对照表；Step S500, generating a current comparison table based on the corresponding relationship between the charging stage and the preset current;
在本实施例中，将各个充电阶段以及充电阶段对应的电流，保存到电流对照表中，当电池充电过程中，可以根据当前电池的充电阶段，获取对应的电流。In this embodiment, each charging stage and the current corresponding to the charging stage are stored in the current comparison table, and during the battery charging process, the corresponding current can be obtained according to the current charging stage of the battery.
所述步骤S200包括：在所述电流对照表中查找所述当前充电阶段对应的预设电流作为所述充电补偿电流。The step S200 includes: looking up a preset current corresponding to the current charging stage in the current comparison table as the charging compensation current.

By using the charging compensation current to supplement the charging voltage, a more accurate voltage can be obtained, and then the power can be displayed more accurately, so that the user can know the charging situation in time or use it better.
基于第一实施例，参照图3，提出本发明电池电量补偿方法的第二实施例，在本实施例中，所述电池电量补偿方法包括：Based on the first embodiment, referring to FIG. 3 , a second embodiment of the battery power compensation method of the present invention is proposed. In this embodiment, the battery power compensation method includes:

在本实施例中，当设备接收到放电指令时，开始启动放电操作，该放电指令一般是由设备运行所触发的，只要设备处于开机状态且没有进行充电，则一直处于放电状态。当设备当前进行放电操作时，利用设备内置的微控制单元MCU的AD模块采集电池的电压，作为电池当前的初始放电电压。In this embodiment, when the device receives a discharge command, it starts the discharge operation. The discharge command is generally triggered by the operation of the device. As long as the device is powered on and not charging, it is always in the discharge state. When the device is currently performing a discharge operation, the AD module of the built-in microcontroller unit MCU is used to collect the voltage of the battery as the current initial discharge voltage of the battery.

在本实施例中，电池当前的放电补偿电流是可以直接通过设备的MCU读取的，并且电池设置在设备的主板上，电子产品出厂时，电池内阻以及接触阻抗是已知的，电池内阻与接触阻抗的总阻值为放电补偿电流对应的电阻值，与充电时的电阻是一致的。电池设置在设备的主板上，电子产品出厂时，电池内阻以及接触阻抗是已知的，电池内阻与接触阻抗的总阻值为充电补偿电流对应的电阻值，将放电补偿电流与电阻值相乘得到放电补偿电压。电池在放电时，AD实际采集的电压值比真实的值虚低，故将电池当前的初始放电电压与放电补偿电压进行相加，得到的和作为补偿后的放电电压，然后利用预设的放电曲线将所述放电电压转换为电池电量。放电电压转换为电量的过程与充电电压转换为电量的过程一致，在此不再赘述。In this embodiment, the current discharge compensation current of the battery can be directly read through the MCU of the device, and the battery is set on the main board of the device. When the electronic product leaves the factory, the internal resistance and contact impedance of the battery are known. The total resistance value of resistance and contact impedance is the resistance value corresponding to the discharge compensation current, which is consistent with the resistance during charging. The battery is set on the main board of the device. When the electronic product leaves the factory, the internal resistance of the battery and the contact impedance are known. The total resistance value of the internal resistance of the battery and the contact impedance is the resistance value corresponding to the charging compensation current. Multiply to get the discharge compensation voltage. When the battery is discharging, the voltage value actually collected by AD is falsely lower than the real value, so the current initial discharge voltage of the battery and the discharge compensation voltage are added, and the obtained sum is used as the compensated discharge voltage, and then the preset discharge voltage is used. The curve converts the discharge voltage into battery power.
