Description

Technical Field

[0001] The present disclosure relates to the field of electronic technology, and in particular to a battery power detection method, device, storage medium, and electronic device. Background Art

[0002] At present, the typical current integration method is generally used to detect battery power. In the current integration method, an ADC (Analog-to-Digital Converter) is generally used to collect battery current in real time, and a single-chip microcomputer is used to integrate and sum the current to calculate the current cumulative consumption. At the same time, the remaining power is displayed in real time on the corresponding display interface for relevant personnel to view. In this way, after the battery current is collected in real time by the ADC, the integral summation operation is performed in the single-chip microcomputer. Frequent multiplication and addition operations are required to obtain the remaining power in real time, resulting in the occupation of the single-chip microcomputer's computing resources, limited function development, and insufficient performance utilization efficiency.

[0059] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0060] Figure 1 FIG. 1 is a flow chart of a battery charge detection method according to an embodiment of the present disclosure. Figure 1 As shown, the method may include the following steps.

[0061] In step 11, the initial battery capacity and the sampling period for sampling the target electrical parameters are obtained.

[0062] Here, the initial power of the battery refers to the power of the battery in the initial stage of sampling. For example, if the battery power detection starts at time T, then the initial power of the battery is the actual power of the battery at time T. There are many ways to determine the initial power of the battery. For example, when determining the initial power of this sampling, since the battery is usually not used during the two sampling processes, the battery power at the end of the previous sampling can be used as the above-mentioned initial power. For another example, the above-mentioned initial power can be predicted by the changes in the battery power during the historical sampling process (such as prediction through a trained model, prediction by drawing a chart, etc.). For another example, the existing method of calculating battery power can be used to calculate the initial power of the battery in real time.

[0063] Therefore, based on the above content, when performing power detection on the battery, it is easy to obtain the initial power of the battery.

[0064] The sampling period for sampling the target electrical parameter can be directly obtained from the sampling device. For example, if the target electrical parameter is sampled by a sampling device ADC during battery charge detection, the sampling period can be directly obtained from the ADC's sampling settings. The sampling period reflects the sampling interval. For example, the target electrical parameter can be current.

[0065] In step 12, first electrical data is determined according to the initial electrical quantity and the sampling period.

[0066] The first electrical data represents the sum of the data collected from each sampling of the target electrical parameter during the sampling period, as the battery's charge level decreases from an initial level to zero. Physically, the first electrical data represents the battery's discharge rate, specifically the discharge efficiency based on the sampling period. The calculation of the first electrical data eliminates the influence of time parameters and serves as a reference.

[0067] For example, the ratio of the initial power level to the sampling period can be determined as the first power data. The initial power level can represent the total power that the battery can supply externally, and the sampling period represents time. The ratio of the two can represent the data that the total power level can be distributed to each sampling moment, eliminating the influence of the time parameter. Furthermore, in general, the total power divided by time is equivalent to efficiency. Therefore, by calculating the ratio of the initial power level to the sampling period, the discharge efficiency of the battery during use can be reflected.

[0068] In step 13, second electrical data at the target sampling moment is acquired.

[0069] The second electrical data is used to represent the sum of data actually collected from each sampling of the target electrical parameter up to the target sampling moment.

[0070] The second electrical data is the data actually collected by the sampling device before the target sampling time. It is actual data and also does not contain time parameters. It is used for comparison with the first electrical data as reference data.

[0071] The target sampling time can be any sampling time. If you need to detect the power level at a certain sampling time, you can use that sampling time as the target sampling time. In actual applications, each sampling time can be used as the target sampling time in turn, thereby achieving the effect of real-time detection of battery power.

[0072] In step 14, if the power indication device is not in the working state, the power status of the battery at the target sampling time is determined according to the difference between the first power data and the second power data.

[0073] The power prompt device is used to provide a more specific reminder of the battery power level, and is used to prompt the battery's SOC value (State Of Charge) and / or remaining power. The prompt methods of the power prompt device include but are not limited to the following: text display, image display, light prompt, and audio playback. For example, if the power prompt device is a display device and prompts are provided by text display, then when the power prompt device is in working state, the battery's SOC value and / or remaining power will be displayed in text on the display screen of the power prompt device.

[0074] Furthermore, when the power reminder device is in working state (for example, the device is awake), it will remind the battery power status, but when it is not in working state (for example, the device is asleep), it will not remind the battery power status.

[0075] Therefore, if the power prompt device is not in working condition, the battery power status cannot be displayed. Therefore, even if the SOC value and the remaining power are calculated, these contents will not be output through the power prompt device. Therefore, in order to save computing resources, it is not necessary to calculate the SOC value and / or the remaining power, but only determine the battery power status at the target sampling time based on the difference between the first electrical data and the second electrical data.

[0076] In a possible implementation, step 14 may include the following steps: Figure 2 As shown:

[0077] In step 21, a difference value obtained by subtracting the second electrical data from the first electrical data is determined;

[0078] In step 22, if the difference is greater than a preset threshold, it is determined that the battery power is sufficient;

[0079] In step 23 , if the difference is less than or equal to the preset threshold, it is determined that the battery power condition is insufficient.

[0080] If the difference between the first and second electrical data is greater than a preset threshold, it indicates that the actual amount of power used by the battery is less than the reference data. Therefore, it can be determined that the battery has sufficient power at the target sampling time. If the difference between the first and second electrical data is less than or equal to the preset threshold, it indicates that the actual amount of power used by the battery exceeds the reference data. Therefore, it can be determined that the battery has insufficient power at the target sampling time. The preset threshold can be set based on actual needs or empirical values. For example, the preset threshold can be set to zero.

[0081] Through the above technical solution, the initial battery charge and the sampling period for sampling the target electrical parameter are obtained. Based on the initial battery charge and the sampling period, first electrical data representing the sum of the data that should be collected for each sampling of the target electrical parameter during the sampling period and when the battery charge changes from the initial charge to zero is determined. Second electrical data representing the sum of the data actually collected for each sampling of the target electrical parameter up to the target sampling time is obtained. If the battery charge indication device is not in an operating state, the battery charge status at the target sampling time is determined based on the difference between the first electrical data and the second electrical data. In this way, by calculating the first electrical data and the second electrical data, the time parameter in the battery charge calculation process is eliminated, so that the difference between the first electrical data and the second electrical data can simply reflect the battery charge status, thereby realizing the function of power monitoring with low computational complexity. Furthermore, when the battery charge indication device is not in an operating state, the SOC value or remaining charge value is not calculated, and the power monitoring is performed only based on the difference between the first electrical data and the second electrical data. Complex multiplication and division operations are not required, thus saving computing resources and device performance.

[0082] Optionally, in Figure 1 Based on the steps shown, the method provided by the present disclosure may further include the following steps:

[0083] If it is determined that the battery power is insufficient, a prompt message indicating that the battery power is insufficient is generated and output.

[0084] That is, if the battery is determined to be low, continued use of the battery may cause problems, so a prompt indicating the low battery status is required. Therefore, a prompt indicating low battery status can be generated and output via a designated device. For example, the designated device can output the prompt via a visual display, an audio prompt, or the like.

[0085] By adopting the above solution, when it is determined that there is a risk of low battery, a certain degree of prompting can be given so that relevant personnel can take certain measures.

[0086] Optionally, the method provided by the present disclosure may further include the following steps: Figure 3 As shown:

[0087] In step 31, if the power indication device is in the working state, the state of charge (SOC) value and / or the remaining power of the battery at the target sampling time are determined based on the first power data and the second power data;

[0088] In step 32 , the SOC value and / or the remaining power is outputted via a power prompt device.

[0089] If the battery level indicator is in working state, it indicates that a more specific battery level indicator can be provided by the battery level indicator. Therefore, the SOC value and / or remaining battery level of the battery at the target sampling time can be determined based on the first and second electrical data.

[0090] For example, the state of charge (SOC) of the battery at the target sampling time can be determined by the following formula (1):

[0091]

[0092] Among them, C is the first electrical data, and D is the second electrical data.

[0093] For example, the remaining battery capacity E at the target sampling time can be determined by the following formula (2):

[0094] E=(CD)*B (2)

[0095] Among them, C is the first electrical data, D is the second electrical data, and B is the sampling period.

[0096] After the SOC value and / or the remaining power are calculated, the SOC value and / or the remaining power can be output through the power prompt device to provide a detailed prompt of the battery power.

[0097] Using the above method, the SOC value and / or remaining power will be calculated only when the power prompt device is in working condition. Only in this case will the battery power detection include complex multiplication and division operations. At the same time, after calculating the SOC value and / or remaining power, a more specific prompt can be given through the power prompt device to facilitate relevant personnel to know the battery power.

[0098] The process of the disclosed solution will be described below through a specific example. Assume that during this battery power detection, the initial battery power is 1000mAh and is sampled by ADC (sampling period is 10ms).

[0099] It can be obtained that the first electrical data = 1000mAh / 10ms = (1000mA*3600s) / 0.01s = 360000A, that is, when the battery power is 0, the sum of the instantaneous sampling current data of all ADCs is 360000A.

[0100] When the detection starts, at sampling time t1, t1 is taken as the target sampling time, and the ADC instantaneously collects data X(t1)=1000A. Then, at this time, the second electrical data=1000A, and the remaining single sampling point electrical data=CD=359000A.

[0101] If the power indication device is in sleep state (not in working state) at this time, the SOC and / or remaining power calculation will not be performed. Only the remaining single sampling point power data will be monitored to see if it approaches 0 (the preset threshold is 0). No multiplication or division operations are involved at this time.

[0102] If the power indication device is in the awake state (in the working state) at this time, the remaining power is calculated as (CD)*B=359000A*10ms=359000A*0.01h / 3600=997.222mAh, and the SOC value is calculated as (CD) / C*100%=99.722%.

[0103] If detection continues, at sampling time t2, t2 is used as the target sampling time, and the ADC instantaneously collects data X(t2) = 19000A. Then the second electrical data = 1000A + 19000A = 20000A, and the remaining single sampling point electrical data = CD = 340000A.

[0104] If the power indication device is in sleep state (not in working state) at this time, the SOC and / or remaining power calculation will not be performed. Only the remaining single sampling point power data will be monitored to see if it approaches 0 (the preset threshold is 0). No multiplication or division operations are involved at this time.

[0105] If the power indication device is in the awake state (in the working state) at this time, the remaining power is calculated as (CD)*B=340000A*10ms=340000A*0.01h / 3600=944.444mAh, and the SOC value is calculated as (CD) / C*100%=94.444%.

[0106] If detection continues, at sampling time t3, t3 is taken as the target sampling time, and the ADC instantaneously collects data X(t3) = 5000A, then the second electrical data = 1000A + 19000A + 5000A = 25000A, and the remaining single sampling point electrical data = CD = 335000A.

[0107] If the power indication device is in sleep state (not in working state) at this time, the SOC and / or remaining power calculation will not be performed. Only the remaining single sampling point power data will be monitored to see if it approaches 0 (the preset threshold is 0). No multiplication or division operations are involved at this time.

[0108] If the power indication device is in the awake state (in working state) at this time, the remaining power is calculated as (CD)*B=335000A*10ms=335000A*0.01h / 3600=930.556mAh, and the SOC value is calculated as (CD) / C*100%=93.056%.

[0109] The subsequent process is analogous. In this way, when there is no need to prompt the specific remaining power and SOC value (that is, the power prompt device is not in a working state), there is no need to perform discrete integral multiplication and division operations. Only the addition and subtraction operations of the first electrical data and the second electrical data proposed in the scheme (that is, the single sampling point related data) can be used to identify the change in power. When the remaining power and SOC value need to be prompted (that is, the power prompt device is in a working state), complex calculations will be performed to provide the power prompt function.

[0110] It should be noted that in the above calculation process, the units of each physical quantity are not limited to the units given in the above examples. The present disclosure does not limit this. It is sufficient to ensure the relative consistency of the units of the physical quantities during calculation. For example, the first electrical data is in A, and the second electrical data should also be in A.
