[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are protected by this application.
[0022] A battery charging circuit is an electronic system that enables safe and efficient charging of batteries. Its core function is to convert power into voltage and current suitable for the battery type, while preventing risks such as overcharging, overcurrent, and short circuits through protection mechanisms. Current battery charging circuit designs often employ simple mean filtering or hardware filtering circuits to output the actual voltage and perform signal simulation, making it difficult to balance control accuracy and voltage reference value readability. Therefore, this application proposes a voltage signal processing method that can separate the actual voltage output from the voltage reference value, balancing control accuracy and voltage reference value readability.
[0023] To illustrate the technical solution of this application, specific embodiments are described below.
[0024] Figure 1This illustration shows a schematic flowchart of a voltage signal processing method provided in an embodiment of this application. This method can be applied to electronic devices. The aforementioned electronic devices can refer to intelligent devices such as computers and smartphones, or devices with autonomous mobility capabilities such as unmanned vehicles and robots; this application does not impose any limitations on this.
[0025] Specifically, the voltage signal processing method described above may include the following steps S101 to S104.
[0026] Step S101: Acquire the raw voltage signal in real time at the acquisition frequency.
[0027] In the embodiments of this application, the raw voltage signal is a digital signal generated based on power demand. The electronic device can acquire the raw voltage signal in real time according to a preset acquisition frequency. The acquisition frequency can be adjusted according to actual needs, for example, acquiring the raw voltage signal once every 1ms.
[0028] Step S102: Determine the current voltage output value based on the original voltage signal, and output the voltage according to the current voltage output value.
[0029] The current voltage output value is an analog signal converted from the original voltage signal, and it serves as the actual voltage output value within the circuit. The output voltage is then used for functions requiring voltage support, such as battery charging and driving mechanical devices.
[0030] Step S103: Upload the current voltage reference value at the reporting frequency.
[0031] Among them, the voltage reference value refers to a derived electrical parameter used for status monitoring. This voltage reference value is not the actual output voltage in the circuit, but it can reflect the voltage output situation and can be used for functions such as operator interface display, historical trend recording, remote status monitoring, system performance analysis, and alarm threshold comparison.
[0032] In the embodiments of this application, the reporting frequency is lower than the acquisition frequency, and the specific value can be set according to the actual situation, for example, the reporting frequency is once every 6 seconds. That is to say, compared with the acquisition frequency, the current voltage reference value can be determined and uploaded at a lower frequency. The current voltage reference value is the voltage reference value that needs to be uploaded now, and it can be determined based on the current voltage output value and historical voltage reference values. Historical voltage reference values are the voltage reference values that have been uploaded in the past.
[0033] In this way, the actual voltage output can be based on the current voltage output value that is actually needed, resulting in higher control precision. The current voltage reference value is related to the current voltage output value and can reflect the actual output situation. However, the actual value is different from the upload frequency and needs to be obtained by combining historical voltage reference values. Therefore, the voltage reference value will not change abruptly with the fluctuation of the current voltage output value, making it more readable.
[0034] In the embodiments of this application, the original voltage signal is acquired in real time at the acquisition frequency, the current voltage output value is determined based on the original voltage signal, and the voltage is output according to the current voltage output value. Then, the current voltage reference value is uploaded at the reporting frequency. The current voltage reference value is determined based on the current voltage output value and historical voltage reference values. Since the reporting frequency is lower than the acquisition frequency, the actual voltage output and the voltage reference value can be separated, taking into account both the control accuracy of the actual voltage output and the readability of the voltage reference value.
[0035] In some embodiments of this application, please refer to Figure 2 The electronic device is equipped with a microcontroller unit (MCU), which has a built-in analog-to-digital converter (ADC) and a storage module. The ADC can continuously acquire the raw voltage signal at the acquisition frequency and store it in the storage module.
[0036] In some embodiments of this application, the storage module may refer to a circular buffer that uses a first-in-first-out (FIFO) queue. When the circular buffer is full, the newly stored original voltage signal can automatically overwrite the oldest data to ensure that the data is updated in real time.
[0037] In some embodiments of this application, determining the current voltage output value based on the original voltage signal may include: acquiring historical voltage signals, calculating the average voltage signal of the original voltage signal and the historical voltage signals, and determining the current voltage output value based on the average voltage signal.
[0038] Specifically, historical voltage signals can be stored in a circular buffer. By using the original voltage signal and historical voltage signals as samples, the sum of all sample values divided by the number of samples yields the average voltage signal.
[0039] In some embodiments of this application, determining the current voltage output value based on the average voltage signal may include: obtaining a reference voltage and the resolution of the digital-to-analog converter, multiplying the average voltage signal by the reference voltage, dividing by the resolution, and obtaining the current voltage output value.
[0040] For example, please refer to Figure 2The electronic device can read raw and historical voltage signals from the storage module. Specifically, the circular buffer can store 1000 raw and historical voltage signals. Dividing the sum of the 1000 data points in the circular buffer by 1000 yields the average voltage signal. This average voltage signal can then be converted to a voltage value, and the current output voltage can be expressed as V. out =ADC value ×V ref / ADC resolution V ref As the reference voltage, ADC resolution For the resolution of the digital-to-analog converter, ADC value This is the average voltage signal.
[0041] In some embodiments of this application, the determination of the current voltage reference value may include: calculating the difference between the current voltage output value and a historical voltage reference value. When the absolute value of the difference is less than or equal to a preset threshold, the historical voltage reference value is used as the current voltage reference value. When the difference is greater than the preset threshold, the sum of the historical voltage reference value and the step value is used as the current voltage reference value. When the difference is less than a negative value of the preset threshold, the difference between the historical voltage reference value and the step value is used as the current voltage reference value.
[0042] Specifically, the historical voltage reference value can refer to the historical voltage reference value V of the previous output. last Please refer to this. Figure 2 It can be used to measure the current voltage value V. out Compared with historical voltage reference value V last Perform a voltage comparison. If the absolute value of the difference is |V out -V last | Less than or equal to the preset threshold V th Then the historical voltage reference value V last Output as the current voltage reference value. If V out -V last Greater than V th The sum of historical voltage reference value and step value V last +V step This serves as the current voltage reference value. If V out -V last <-V th At this point, the difference V between the historical voltage reference value and the step value can be used. last -V step Used as a reference value for the current voltage.
[0043] Wherein, step value V step It can be set to a preset threshold V step It can also be set to other values according to the actual situation.
[0044] In some embodiments of this application, the absolute value of the difference |V can be used as a basis. out -V last | Dynamically adjust the step value; for example, the larger the absolute value of the difference, the larger the step value. Specifically, the step value V step It can be represented as: V step =max(V min ,min(V max ,k×∣V out -V last ∣)). Among them, V max and V min These represent the maximum and minimum step values, respectively. k is a preset adjustment coefficient.
[0045] In other embodiments of this application, the step value V step =(V max -V min ) / (T response ×f report ), where T response f represents the system response time. report This indicates the reporting frequency. This allows the step value to be adjusted according to the system response time requirements.
[0046] In some embodiments of this application, the current voltage reference value may be written to a register or sent to a communication interface to upload the current voltage reference value.
[0047] In some embodiments of this application, the voltage output can be used to charge the battery. The voltage signal processing method may further include: dynamically adjusting the acquisition frequency within a single upload cycle of the current voltage reference value based on the battery's state of charge.
[0048] Specifically, when the battery is in constant current charging, the voltage rises rapidly, and the first sampling frequency can be used. When the battery is in constant voltage charging, the voltage rises slowly, and the second sampling frequency can be used. The first sampling frequency is higher than the second sampling frequency.
[0049] Therefore, within a single upload cycle, the original voltage signal can be acquired based on the dynamic acquisition frequency, and the current voltage reference value can be determined based on the original voltage signal and the historical voltage signal. This allows the current voltage reference value to simultaneously reference a large number of samples when the voltage changes rapidly under constant current charging and a small number of samples when the voltage changes slowly under constant voltage charging, making the current voltage reference value smoother and more consistent with the charging characteristics.
[0050] In other embodiments of this application, the voltage signal processing method may further include: calculating the voltage change rate based on the current voltage output value; increasing the acquisition frequency and / or decreasing the reporting frequency when the voltage change rate exceeds a first threshold; and decreasing the acquisition frequency and / or increasing the reporting frequency when the voltage change rate is lower than a second threshold.
[0051] Specifically, based on the current voltage output value and historical voltage output values, the rate of change of the voltage output can be calculated. When the rate of change of voltage exceeds a first threshold, the acquisition frequency can be increased and / or the reporting frequency can be decreased, thereby improving voltage control accuracy when the voltage changes rapidly and reducing the resources occupied by uploading the current voltage reference value to the original voltage signal acquisition. When the rate of change of voltage exceeds the first threshold, the acquisition frequency is decreased and / or the reporting frequency is increased, so that the current voltage reference value approaches the current voltage output value more quickly.
[0052] It should be noted that, for the sake of simplicity, the aforementioned method embodiments are described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, because based on this application, some steps can be performed in other orders.

[0057] The voltage reference value uploading unit 303 is used to upload the current voltage reference value at the reporting frequency, wherein the current voltage reference value is determined based on the current voltage output value and historical voltage reference values, and the reporting frequency is lower than the acquisition frequency.
[0058] In some embodiments of this application, the voltage reference value uploading unit 303 can be used to: calculate the difference between the current voltage output value and the historical voltage reference value; when the absolute value of the difference is less than or equal to a preset threshold, use the historical voltage reference value as the current voltage reference value; when the difference is greater than the preset threshold, use the sum of the historical voltage reference value and the step value as the current voltage reference value; when the difference is less than the negative value of the preset threshold, use the difference between the historical voltage reference value and the step value as the current voltage reference value.
