[0043] Example 1
[0044] This embodiment provides a method for calculating the remaining power of a dry cell. Figure 1 As shown, the calculation method includes:
[0045] S1. Obtaining a difference discharge curve of a dry cell and a current voltage of the dry cell, wherein the difference discharge curve is obtained by subtracting voltage discharge curves of the dry cell under different loads;
[0046] In a specific implementation, after obtaining the voltage discharge curves under different loads, these curves are subjected to difference calculation to obtain the difference discharge curve of the dry cell. The difference discharge curve can reflect the relationship between the load capacity and the remaining power of the dry cell.
[0047] In a specific example, Figure 2 As shown, two voltage discharge curves are obtained under different loads, and a third difference discharge curve can be obtained by performing a difference operation on the two voltage discharge curves.
[0048] S2. Obtaining the remaining power of the dry battery according to the current voltage of the dry battery and the difference discharge curve.
[0049] In an optional embodiment, the step of obtaining the remaining power of the dry battery according to the current voltage of the dry battery and the difference discharge curve specifically includes: substituting the current voltage of the dry battery into the function corresponding to the difference discharge curve to obtain the remaining power corresponding to the difference discharge curve; and substituting the current voltage of the dry battery into the function corresponding to the voltage discharge curve of the dry battery under different loads to obtain the remaining power corresponding to the voltage discharge curve; obtaining the remaining power of the dry battery according to the remaining power corresponding to the difference discharge curve and the remaining power corresponding to the voltage discharge curve.
[0050] In a specific implementation, the measured current voltage value of the dry battery is substituted into a function that can describe the differential discharge curve, and an output value is calculated. This output value represents the remaining power corresponding to the differential discharge curve. At the same time, the measured current voltage value of the dry battery is substituted into a function that can describe the voltage discharge curve of the dry battery under different loads, and an output value is calculated. This output value can represent the remaining power corresponding to the voltage discharge curve. Based on the corresponding remaining power values obtained from the differential discharge curve and the voltage discharge curve, a comprehensive calculation is performed to obtain the comprehensive remaining power of the dry battery. This comprehensive remaining power can be more accurately expressed as the remaining power of the dry battery.
[0051] In a specific example, the current voltage of the dry battery is substituted into the function corresponding to the voltage discharge curve of the dry battery under a high load condition with a current of 1A, and the remaining power corresponding to the voltage discharge curve under the high load is obtained. The remaining power of the dry battery is obtained based on the remaining power corresponding to the difference discharge curve and the remaining power corresponding to the voltage discharge curve under the high load.
[0052] In another specific example, the current voltage of the dry battery is substituted into the function corresponding to the voltage discharge curve of the dry battery under a low load of 0.067A to obtain the remaining power corresponding to the voltage discharge curve under the low load, and the remaining power of the dry battery is obtained based on the remaining power corresponding to the difference discharge curve and the remaining power corresponding to the voltage discharge curve under the low load.
[0053] In another specific example, the current voltage of the dry battery is substituted into the function corresponding to the voltage discharge curve of the dry battery under a high load of 1A and the function corresponding to the voltage discharge curve under a low load of 0.067A, respectively, to obtain the remaining power corresponding to the voltage discharge curve under high load and the remaining power corresponding to the voltage discharge curve under low load. According to the remaining power corresponding to the difference discharge curve, the remaining power corresponding to the voltage discharge curve under high load and the remaining power corresponding to the voltage discharge curve under low load, the remaining power of the dry battery is obtained by comprehensive calculation based on the above three remaining power values. By combining the voltage discharge curves under different load conditions, the remaining power of the dry battery can be more comprehensively evaluated, thereby improving the accuracy of the remaining power estimation.
[0054] In a specific example, the remaining power corresponding to the difference discharge curve and the remaining power corresponding to the voltage discharge curve may be weightedly calculated to obtain the remaining power of the dry cell.
[0055] In an optional embodiment, the calculation method also includes: obtaining the differential voltage curve of the dry battery; the step of obtaining the remaining power of the dry battery according to the current voltage of the dry battery and the differential discharge curve specifically includes: substituting the current voltage of the dry battery into the function corresponding to the differential discharge curve to obtain the remaining power corresponding to the differential discharge curve; and substituting the current voltage of the dry battery into the function corresponding to the differential voltage curve to obtain the remaining power corresponding to the differential voltage curve; obtaining the remaining power of the dry battery according to the remaining power corresponding to the differential discharge curve and the remaining power corresponding to the differential voltage curve.
[0056] In a specific implementation, the differential voltage curve of a battery refers to the rate of change of the battery voltage under a unit charge change. The difference of a discrete signal corresponds to the differential (first-order derivative) of a function in a continuous domain. The advantage of a differential signal is that it has a relatively smooth characteristic in itself, and is relatively stable in long-term changes such as a discharge process with a monthly cycle, and is relatively unaffected by environmental interference. The measured current voltage value of the dry cell is substituted into a function that can describe the differential discharge curve, and an output value is calculated. This output value represents the remaining power corresponding to the differential discharge curve. At the same time, the measured current voltage value of the dry cell is substituted into a function that can describe the differential voltage curve of the dry cell, and another output value is calculated. This output value represents the remaining power corresponding to the differential voltage curve. The two remaining power values are weighted and calculated to obtain a final value that can represent the remaining power of the dry cell, so as to more accurately evaluate the remaining power of the dry cell.
[0057] In an optional embodiment, the calculation method also includes: obtaining the differential voltage curve of the dry battery; the step of obtaining the remaining power of the dry battery according to the current voltage of the dry battery and the differential discharge curve specifically includes: substituting the current voltage of the dry battery into the function corresponding to the differential discharge curve to obtain the remaining power corresponding to the differential discharge curve; and substituting the current voltage of the dry battery into the function corresponding to the voltage discharge curve of the dry battery under different loads to obtain the remaining power corresponding to the voltage discharge curve; and substituting the current voltage of the dry battery into the function corresponding to the differential voltage curve to obtain the remaining power corresponding to the differential voltage curve; obtaining the remaining power of the dry battery according to the remaining power corresponding to the differential discharge curve, the remaining power corresponding to the voltage discharge curve, and the remaining power corresponding to the differential voltage curve.
[0058] In a specific implementation, the measured current voltage value of the dry battery is substituted into a function that can describe the differential discharge curve to obtain the remaining power corresponding to the differential discharge curve, the measured current voltage value of the dry battery is substituted into a function that can describe the voltage discharge curve of the dry battery under different loads to calculate the remaining power corresponding to the voltage discharge curve, the measured current voltage value of the dry battery is substituted into a function that can describe the differential voltage curve of the dry battery to calculate the remaining power corresponding to the differential voltage curve, and the multiple remaining powers obtained are weightedly calculated to obtain a comprehensive calculated value to represent the remaining power of the dry battery.
[0059] In a specific example, in the process of weighted calculation of multiple remaining powers, if the current dry battery is under high load, a higher weight is given to the remaining power corresponding to the voltage discharge curve under high load; if the current dry battery is under low load, a higher weight is given to the remaining power corresponding to the voltage discharge curve under low load.
[0060] In another specific example, if the dry cell battery is in the initial use stage, that is, the battery is fully charged, then in the process of weighted calculation of multiple remaining charges, a higher weight is set for the remaining charge corresponding to the voltage discharge curve under high load and the remaining charge corresponding to the voltage discharge curve under low load. After the dry cell battery has been used for a period of time, then in the process of weighted calculation of multiple remaining charges, a higher weight is set for the remaining charge corresponding to the difference discharge curve and the remaining charge corresponding to the differential voltage curve.
[0061] In an optional embodiment, the step of obtaining the voltage discharge curve of the dry battery under different loads specifically includes: obtaining the voltage and corresponding power of the dry battery under different loads within a preset time period; and fitting the voltage and the corresponding power to obtain the voltage discharge curve of the dry battery under different loads.
[0062] In a specific implementation, the voltage and corresponding power data of the dry cell under different loads are recorded in a preset time period, and a corresponding curve is obtained by fitting the multiple measured data. The fitted curve is the voltage discharge curve of the dry cell under different loads. Specifically, different dry cells need to select different fitting methods for curve fitting. In a specific example, Figure 3 As shown, the voltage discharge curve of the dry cell under a load of 0.067A is obtained by Fourier series fitting, wherein the horizontal axis X represents time and the vertical axis Y represents voltage.
