Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a flowchart of a battery charge level detection method provided according to an embodiment of the present disclosure. As shown in fig. 1, the method may include the following steps.
In step 11, an initial charge of the battery and a sampling period for sampling the target electrical parameter are obtained.
Here, the initial charge of the battery refers to the charge of the battery at the initial stage of sampling, for example, the charge detection of the battery is started at time T, and then the initial charge of the battery is the actual charge of the battery at time T. There are various methods for determining the initial charge of the battery. For example, when determining the initial power amount of the current sampling, since the battery is not used in the two sampling processes, the battery power amount at the end of the previous sampling may be used as the initial power amount. For another example, the initial power amount may be predicted according to a change of the battery power amount in the history sampling process (e.g., predicting through a trained model, predicting through a graph, etc.). For another example, the initial charge of the battery may be calculated in real time using an existing method of calculating the charge of the battery.
Therefore, based on the above, when detecting the electric quantity of the battery, the initial electric quantity of the battery is easily acquired.
The sampling period for sampling the target electrical parameter may be obtained directly by the sampling device. For example, if the target electrical parameter is sampled by the sampling device ADC when detecting the electrical quantity of the battery, the sampling period may be directly obtained from the sampling setting of the ADC, and the sampling period reflects the sampling time interval. Illustratively, the target electrical parameter may be current.
In step 12, first electrical data is determined based on the initial electrical quantity and the sampling period.
The first electrical data are used for representing the sum of data which are sampled according to a sampling period and are acquired by sampling the target electrical parameters in each time when the battery electric quantity is changed from the initial electrical quantity to zero. In a physical sense, the first electrical data may characterize the discharge rate of the battery, i.e. the discharge efficiency based on the sampling period, and the calculation of the first electrical data eliminates the influence of the time parameter, which may be used as reference data.
For example, a ratio of the initial electrical quantity and the sampling period may be determined as the first electrical data. The initial electric quantity can represent the total electric quantity of the battery which can supply power outwards at this time, the sampling period represents time, the ratio of the initial electric quantity to the sampling period can represent the data of the total electric quantity which can be scattered to each sampling moment, and the influence of time parameters can be eliminated. In addition, generally, the total amount divided by the time is equivalent to the efficiency, so that the discharge efficiency in the use process of the battery can be reflected by calculating the ratio of the initial electric quantity to the sampling period.
In step 13, second electrical data is acquired at a target sampling instant.
And the second electrical data is used for representing the sum of data actually acquired by sampling the target electrical parameter at each time when the target sampling time is reached.
The second electrical data are the data actually acquired by the sampling device before the target sampling instant, which belong to the actual data and likewise do not contain a time parameter for comparison with the first electrical data as reference data.
The target sampling time can be any sampling time, if the electric quantity of which sampling time needs to be detected, the sampling time can be used as the target sampling time, and in practical application, each sampling time can be used as the target sampling time in sequence, so that the effect of detecting the electric quantity of the battery in real time is achieved.
In step 14, if the power prompting device is not in the working state, the power condition of the battery at the target sampling time is determined according to the difference value between the first electrical data and the second electrical data.
The electric quantity prompting device is used for specifically prompting the electric quantity Of the battery and prompting the SOC (State Of Charge) value and/or the residual electric quantity Of the battery. The prompting modes of the power prompting device include, but are not limited to, the following: character display, image display, light prompt and audio play. For example, if the power prompting device is a display device and prompts in a text display manner, when the power prompting device is in an operating state, the SOC value and/or the remaining power of the battery may be displayed in text on a display screen of the power prompting device.
The power prompting device prompts the battery power status when the device is in an operating state (e.g., the device is awake), and cannot prompt the battery power status when the device is not in the operating state (e.g., the device is asleep).
Therefore, if the power prompting device is not in the working state, the power condition of the battery cannot be displayed, and even if the SOC value and the remaining power are calculated, the contents cannot be output through the power prompting device, so that in order to save calculation resources, the SOC value and/or the remaining power do not need to be calculated, and the power condition of the battery at the target sampling time can be determined only according to the difference value between the first electrical data and the second electrical data.
In one possible embodiment, step 14 may include the following steps, as shown in fig. 2:
in step 21, determining a difference value obtained by subtracting the second electrical data from the first electrical data;
in step 22, if the difference is greater than the preset threshold, determining that the electric quantity of the battery is sufficient;
in step 23, if the difference is smaller than or equal to the preset threshold, it is determined that the battery capacity is insufficient.
If the difference value obtained by subtracting the second electrical data from the first electrical data is larger than the preset threshold value, the fact that the actually used electric quantity of the battery is smaller than the reference data is shown, and therefore the fact that the electric quantity of the battery is sufficient at the target sampling moment can be determined. And if the difference value obtained by subtracting the second electrical data from the first electrical data is less than or equal to the preset threshold value, the actual electric quantity of the battery exceeds the reference data, and therefore, the electric quantity shortage of the battery at the target sampling moment can be determined. The preset threshold value can be set according to actual requirements or empirical values. For example, the preset threshold may be set to zero.
According to the technical scheme, the initial electric quantity of the battery and the sampling period of the target electric parameter are obtained, the first electric data which are used for representing the sum of data which are sampled according to the sampling period and are obtained in the process that the electric quantity of the battery is changed from the initial electric quantity to zero and are obtained in each sampling process of the target electric parameter are determined according to the initial electric quantity and the sampling period, the second electric data which represent the sum of data which are actually obtained by the target electric parameter at the moment of sampling and are obtained in each sampling process are obtained, and if the electric quantity prompting device is not in a working state, the electric quantity condition of the battery at the target sampling moment is determined according to the difference value of the first electric data and the second electric data. Therefore, the time parameter in the electric quantity operation processing is eliminated by calculating the first electric data and the second electric data, so that the difference value of the first electric data and the second electric data can simply reflect the electric quantity condition of the battery, the electric quantity monitoring function is further realized, and the operation complexity is low. And when the electric quantity prompting equipment is not in a working state, the SOC value or the residual electric quantity cannot be calculated, electric quantity monitoring is only carried out through the difference value of the first electric data and the second electric data, complex multiplication and division operations are not needed, operation resources are saved, and equipment performance is saved.
Optionally, on the basis of the steps shown in fig. 1, the method provided by the present disclosure may further include the following steps:
and if the situation that the electric quantity of the battery is insufficient is determined, generating and outputting prompt information for indicating that the electric quantity of the battery is insufficient.
That is, if it is determined that the battery is low, some problems may occur if the battery is continuously used, and therefore, it is necessary to indicate that the battery is low. Therefore, it is possible to generate the prompt information indicating that the battery power is insufficient and output the prompt information through the specified device. Illustratively, the designated device may output the reminder information by means such as a visual display, an audible reminder, or the like.
By adopting the scheme, when the risk of insufficient electric quantity of the battery is determined, a certain degree of prompt can be performed so that related personnel can take certain measures.
Optionally, the method provided by the present disclosure may further include the following steps, as shown in fig. 3:
in step 31, if the electric quantity prompting device is in a working state, determining a state of charge (SOC) value and/or a residual electric quantity of the battery at a target sampling moment according to the first electric data and the second electric data;
in step 32, the SOC value and/or the remaining power are output through the power prompting device.
If the electric quantity prompting equipment is in a working state, the electric quantity prompting equipment can be used for carrying out specific electric quantity prompting. Therefore, the SOC value and/or the remaining capacity of the battery at the target sampling timing may be determined based on the first electrical data and the second electrical data.
For example, the state of charge SOC value of the battery at the target sampling time may be determined by the following equation (1):
where C is the first electrical data and D is the second electrical data.
For example, the remaining capacity E of the battery at the target sampling time may be determined by the following equation (2):
E＝(C-D)*B (2)
where C is the first electrical data, D is the second electrical data, and B is the sampling period.
After the SOC value and/or the residual capacity are calculated, the SOC value and/or the residual capacity can be output through the capacity prompting device so as to prompt the battery capacity in detail.
By adopting the mode, only under the condition that the electric quantity prompting equipment is in a working state, the calculation of the SOC value and/or the residual electric quantity can be carried out, only under the condition, the electric quantity detection of the battery can contain complex multiplication and division operations, and meanwhile, after the SOC value and/or the residual electric quantity are calculated, the specific prompt can be carried out through the electric quantity prompting equipment, and the battery electric quantity can be conveniently known by related personnel.
The procedure of the disclosed solution will be explained below by a specific example. Assuming that the initial charge of the battery is 1000mAh at the time of the battery charge detection, sampling is performed by the ADC (sampling period is 10 ms).
It can be seen that the first electrical data is 1000mAh/10ms (1000mA 3600s)/0.01s 360000A, i.e. when the battery level is 0, the sum of the instantaneous sampled current data of all ADCs is 360000A.
When the detection is started, at the sampling time t1, with t1 as the target sampling time, the ADC instantaneous acquisition data X (t1) is 1000A, the second electrical data is 1000A, and the remaining single sampling point electrical data is 359000A.
If the electric quantity prompting device is in a sleep state (not in a working state), the SOC and/or the residual electric quantity are not calculated, and only whether the residual single sampling point electric data tend to 0 (the preset threshold value is 0) or not is monitored, and at the moment, multiplication and division operation is not involved.
If the power prompting device is in an awake state (in an operating state), the remaining power is calculated to be (C-D) × B ═ 359000a ═ 10ms ═ 359000a × (0.01 h/3600 ═ 997.222mAh, and the SOC value is calculated to be (C-D)/C ═ 100% ═ 99.722%.
If the detection is continued, at the sampling time t2, with t2 as the target sampling time, the ADC instantaneous acquisition data X (t2) is 19000A, at which time the second electrical data is 1000A +19000A is 20000A, and the remaining single-sampling-point electrical data is C-D is 340000A.
If the electric quantity prompting device is in a sleep state (not in a working state), the SOC and/or the residual electric quantity are not calculated, and only whether the residual single sampling point electric data tend to 0 (the preset threshold value is 0) or not is monitored, and at the moment, multiplication and division operation is not involved.
If the power prompting device is in an awake state (in an operating state), the remaining power is calculated to be (C-D) × B ═ 340000a ═ 10ms ═ 340000a × (0.01 h/3600 ═ 944.444mAh, and the SOC value is calculated to be (C-D)/C ═ 100% ═ 94.444%.
If the detection is continued, at the sampling time t3, with t3 as the target sampling time, the ADC instantaneous acquisition data X (t3) is 5000A, at which time the second electrical data is 1000A +19000A +5000A is 25000A, and the remaining single-sampling-point electrical data is C-D is 335000A.
If the electric quantity prompting device is in a sleep state (not in a working state), the SOC and/or the residual electric quantity are not calculated, and only whether the residual single sampling point electric data tend to 0 (the preset threshold value is 0) or not is monitored, and at the moment, multiplication and division operation is not involved.
If the power prompting device is in an awake state (in an operating state), the remaining power is calculated to be (C-D) × B ═ 335000a ═ 10ms ═ 335000a × (0.01 h/3600 ═ 930.556mAh, and the SOC value is calculated to be (C-D)/C ═ 100% ═ 93.056%.
The subsequent processes are analogized. In this way, when the specific remaining power and the SOC value do not need to be prompted (i.e., the power prompting device is not in the operating state), discrete integral multiplication and division operation is not needed, the change of the power can be identified only by performing addition and subtraction operation on the first electrical data and the second electrical data (i.e., the single sampling point related data) provided by the scheme, and when the remaining power and the SOC value need to be prompted (i.e., the power prompting device is in the operating state), the power prompting function can be provided by performing complex calculation.
It should be noted that, in the above calculation process, the units of the physical quantities are not limited to the units given in the above example, and the present disclosure does not limit this, and it is sufficient to ensure that the units of the physical quantities are relatively consistent when calculating, for example, the first electrical data is in units of a, and the second electrical data is also in units of a.
