Description
Technical Field
The present application relates to the field of smart home technologies, and in particular, to a method and an apparatus for determining battery power, an electronic device, a computer-readable storage medium, and a computer program product.
Background
The smart lock usually uses a dry battery or a lithium battery as a power source, and the battery as the power source means that the battery is completely consumed. To enhance the user experience, the manufacturer may typically inform the user of the remaining power of the smart lock in various ways.
At present, the more conventional scheme for acquiring the remaining capacity is as follows: the voltage data of a battery installed in the intelligent lock is acquired through a main control MCU (Micro Controller Unit), and the voltage data is directly converted into electric quantity data, so that the residual electric quantity is acquired. On one hand, considering the characteristic that the power consumption of the battery is limited, the master control MCU needs to be set in a sleep state or an awake state according to a scene, specifically: the main control MCU can not acquire the voltage data of the battery in real time when in the dormant state, and can acquire the voltage data of the battery only when in the awakening state, namely the voltage data of the battery can not be acquired in real time. On the other hand, it is difficult to calculate the voltage data of the battery using a current integration method or a more advanced SOC estimation method (such as a kalman filter method) in consideration of the limited processing capability of the MCU. And finally, converting the obtained voltage data into electric quantity data so as to obtain the residual electric quantity of the battery.
In addition, if the voltage data is directly converted into the electric quantity data, instantaneous larger current is caused by actions such as unlocking, so that the measured voltage data drops more, correspondingly the obtained electric quantity data drops more, and the fact is obviously not met; if the simple filtering processing is directly performed on the plurality of voltage data, the change of the voltage data cannot be immediately reflected when the battery is replaced by the user, that is, the correspondingly obtained voltage data cannot be immediately reflected.
Therefore, the solutions for acquiring the power provided by the related art all lead the user to recognize the wrong battery power. Thus, the user experience still needs to be improved.

The embodiment of the application provides a method for determining battery electric quantity, which comprises the following steps: acquiring the current voltage value of the battery, and calculating the historical voltage mean value of the voltage values at a plurality of historical moments; when the actual voltage value at the current moment is calculated, acquiring a weight value (namely an occupation ratio) corresponding to the current voltage value based on the current voltage value, indirectly acquiring a weight value corresponding to a historical voltage average value according to the weight value, and finally calculating a target voltage value (namely the actual voltage value of the battery) of the battery at the current moment according to the current voltage value and the weight value thereof, and the historical voltage average value and the weight value thereof; further, the remaining capacity of the battery at the current moment is determined according to the corresponding relation between the voltage value and the capacity information. That is to say, when the actual voltage value at the current time is obtained, in order to avoid that the obtained current voltage value is not accurate enough due to various interferences, the obtained current voltage value is not only used as the actual voltage value, but the actual voltage value is calculated by combining the current voltage value and the historical voltage value, and finally the actual voltage value at the current time is calculated according to the weight occupied by each type of voltage value. Even under some scenes, for example, under the condition that other operations on the battery influence the acquired current voltage value to be inaccurate, the accurate actual voltage value can be normally acquired, so that the residual capacity of the battery at the current moment is acquired. Therefore, the embodiment of the application can obtain more accurate electric quantity information.
Next, the contents of step S220 and step S230 will be explained in detail.
In an optional embodiment, determining a weight value corresponding to the current voltage value according to the current voltage value may specifically include the following steps Sa1 to Sa3.
Sa1, determining a first parameter based on the current voltage value and a target voltage value of the battery at the last moment; the target voltage value of the battery at the previous moment corresponds to the remaining capacity at the previous moment.
Optionally, calculating an absolute value of a difference between the current voltage value and the target voltage value at the previous moment; acquiring a third parameter from a preset second range; a first parameter is determined based on the ratio and a preset value. Specifically, a ratio of the absolute value to the third parameter is determined, and a difference between the ratio and a preset value is used as the first parameter.
The third parameter is a voltage value, and may specifically represent a magnitude of a voltage change.
In one example scenario, the present voltage value is taken as P M The target voltage value corresponding to the residual capacity at the previous moment is P pre (ii) a The third parameter is delta P, and the value range of the delta P is between 0.2v and 0.4 v; the calculation process of the ratio E can refer to the following equation 3. If Δ P =0.2, the change in the corresponding electrical quantity is 10%, and if Δ P =0.4, the change in the corresponding electrical quantity is 20%.
and Sa2, acquiring a second parameter from a preset first range.
In one example scenario, a second parameter a is selected. Wherein, the value range of A is between 10 and 1000.
And Sa3, performing exponentiation by using the first parameter as an exponent and the second parameter as a base number, and determining an operation result as a weight value corresponding to the current voltage value.
In yet another example scenario, where the preset value may be 1, the first parameter is E-1. The calculation process of the first weight value W may refer to the following equation 4.
optionally, when E is greater than the preset value, E is set as the preset value. Specifically, if P M Relative to P pre The variation is large, then the probability of E being greater than the preset value is large, and the maximum value of W is 1. Therefore, it is necessary to set E = a preset numerical value in the case where E is larger than the preset numerical value, so that the maximum value of W can be made 1. That is, if E is calculated when the predetermined value is 1>1, E =1 is set.
Optionally, when E is calculated for the first time, P pre Do not exist and cannot be according to the publicEquation 3 calculates E, so that the embodiment of the present application also determines E by providing another preset value (e.g., value 0), that is, setting E =0.
For the smart lock, if the battery is replaced, the voltage value of the battery may change suddenly and greatly, and then the calculated E may be greater than the preset value. Therefore, P should be increased at this time M Weight in calculating the target voltage value. If E is equal to a preset value, the calculated first weighted value W is 1, that is, when the target voltage value is calculated, the obtained P is used M Mainly comprises the following steps. And, when acquiring the current voltage value, the voltage value acquired at the last moment of the awake state may be used as the current voltage value.
For the intelligent lock, if the intelligent lock is in an unlocking scene, the current is increased instantly due to unlocking action, the voltage falls to a certain extent relative to a normal value, and the normal unlocking process does not consume too much power consumption, so that the voltage change is normal. In this case, the calculated target voltage value can be made to approach the actual voltage value of the battery in conjunction with the history voltage value.
After the remaining capacity at the current moment is calculated, the remaining capacity can be displayed to the user.
In an alternative embodiment, the device is further configured with a display screen by which at least the remaining amount of the battery at the current moment is displayed.
