Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the specific embodiments described herein are illustrative of the relevant application and are not limiting of the application. It should be noted that, for the convenience of description, only the parts related to the related applications are shown in the drawings.
With the advance of technology and the rapid development of integrated circuits, many electronic devices are miniaturized, and these portable electronic devices (such as mobile phones, smart phones, digital cameras, digital video cameras, notebook computers, etc.) require power to operate, wherein the source of the power is batteries. The accurate measurement of the available electric quantity of the battery, which is used as an energy storage and power supply element of various mobile devices, is a very critical problem in the development of intelligent mobile devices.
In order to better monitor the battery power and realize the intelligent charging and discharging management of the mobile device, the prior art scheme usually realizes the monitoring of the power through a current sampling circuit composed of a power management integrated circuit PMIC and a current detection resistor. Specifically, the current change passing through the current detection resistor can be accurately collected and integrated according to the PMIC, so that the current electric quantity variable quantity is determined, and the actual electric quantity display of the current mobile equipment is updated.
However, when the current sampling circuit is abnormal, the deviation of the collected current is large, which causes the deviation between the displayed electric quantity and the actual electric quantity; for example, a rapid drop in charge occurs upon discharge, with less drop in the actual capacity of the device battery. Therefore, the actual electric quantity change of the battery cannot be obtained in the existing electric quantity detection mode, the detection accuracy is poor, and the electric quantity detection precision is reduced.
In order to solve the problems of the existing electric quantity detection mechanism, the embodiment of the application provides an electric quantity detection method and device, and a storage medium. Specifically, the electric quantity detection equipment can judge whether the electric quantity detection is abnormal according to the real-time current of the battery and the preset reference current corresponding to the current state, and then when the electric quantity detection is judged to be abnormal, the electric quantity change prediction value of the battery is further determined based on the voltage change parameter of the battery and the preset reference current corresponding to the current state, so that the actual electric quantity change of the battery can be accurately obtained, and the accuracy of the electric quantity detection is further improved.
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Fig. 1 is a schematic flow chart illustrating an implementation process of the power detection method provided in the embodiment of the present application, and as shown in fig. 1, in the embodiment of the present application, the method for performing power detection by a power detection device may include the following steps:
In the embodiment of the application, the electric quantity detection device can detect the state and the current of the battery in real time so as to obtain the current state and the real-time current of the battery.
In the embodiments of the present application, the battery is a rechargeable and recyclable battery, such as a lithium battery, a nickel cadmium battery, and a nickel metal hydride battery. The power detection device may be any portable electronic device that requires a battery to support operation. For example, a tablet, a mobile phone, a smartphone, a portable wearable electronic device, a digital camera, a digital video camera, a notebook, or a player for music, video, etc. The present invention is not limited to this, and may be an electric bicycle, an electric vehicle, or the like supported by a battery. In a specific implementation process, the electric quantity detection method in the embodiment of the present application may be executed by one device alone, or may be executed by multiple devices in cooperation.
It should be noted that, in the embodiment of the present application, the current state of the battery may include a rest non-operating state, a charging state, and a discharging state. Alternatively, when the battery is mounted to the power detection apparatus and the power detection apparatus is powered by the battery, the current state of the battery may be determined by detecting the current direction or by detecting the swelling force of the battery.
Specifically, the positive current direction of the battery is assumed to be flowing out of the positive electrode of the battery and flowing into the negative electrode; the negative current direction is from the positive electrode of the battery to the negative electrode. If the current is in the forward current direction and the current is equal to or larger than the minimum threshold of the working discharge current, judging that the current state is a discharge state; if the current is in the reverse current direction and the current is equal to or larger than the minimum threshold of the charging current, judging that the current state is the charging state; if the input/output current value of the battery is small in a non-working state between a discharging state and a charging state (for example, the electronic device is in a standby state or a shutdown state), the battery is in a standing non-working state at the moment.
Specifically, in the process of charging/discharging the battery, the lithium ions are embedded/separated in the pole pieces, so that the thickness of the pole pieces can be correspondingly shrunk and expanded, and therefore, the electric quantity detection equipment can be configured with a sensor which can be arranged at a position between the battery end plate and the battery core and is in contact with the battery core, so as to obtain the expansion force generated by the battery in real time, and determine the current state of the battery according to the corresponding relationship between the expansion force and the charging/discharging state. Alternatively, the sensor may employ a pressure sensor (e.g., a piezoresistive membrane).
Further, in the embodiment of the application, the electric quantity detection device is provided with a current sampling circuit, and the current flowing through the current detection resistor is collected in real time through the current sampling circuit so as to determine the real-time current of the battery. If the current state is a discharging state, the real-time current of the battery is the discharging current; and if the current state is the charging state, the real-time current of the battery is the charging current.
Further, in the embodiment of the application, the electric quantity detection device may also detect a real-time open-circuit voltage, a real-time temperature (i.e., a battery internal temperature) of the battery, and a current working scenario corresponding to the battery while detecting a real-time current and a current state.
Further, in the embodiment of the present application, after the electric quantity detection device detects the current state and the real-time current of the battery, the real-time current and the current state may be combined to further determine whether the current electric quantity detection is abnormal.
In the embodiment of the application, after the current state and the real-time current of the battery are detected by the electric quantity detection device, the preset reference current corresponding to the current state can be determined, so that whether the electric quantity detection is abnormal or not is further judged according to the real-time current and the preset reference current.
It should be noted that, in the embodiment of the present application, the power detection device may set the reference current in advance for different states, that is, different states correspond to different reference currents. After determining the charge/discharge state of the battery, the power detection device may further determine a reference current corresponding to the charge/discharge state, that is, an ideal charge/discharge current.
It can be understood that, as a certain amount of heat is generated in the charging process, the temperature of the battery changes, so that the temperature of the battery can more directly reflect the magnitude of the charging current; during discharging, the power consumption of the electric quantity detection equipment is different under different working scenes (such as calling, playing games, video calls and the like), namely the required current is different, so that the current discharging current can be reflected by using different working scenes. In summary, the electric quantity detection device may determine different parameters for reflecting the magnitude of the current in different states, and then establish corresponding relationships between the different parameters and the preset reference current in the different states.
Optionally, the electric quantity detection device may pre-establish a corresponding relationship between the temperature and the charging reference current, and a corresponding relationship between the working scene and the discharging reference current. When the current state is a charging state, the electric quantity detection device can acquire a first reference current corresponding to the real-time temperature and determine the first reference current as a preset reference current; the preset reference current is an ideal charging current of the battery at a real-time temperature. When the current state is the discharging state, the electric quantity detection device can acquire a second reference current corresponding to the current working scene and determine the second reference current as a preset reference current; the preset reference current is an ideal discharge current of the battery under the current working scene.
It should be noted that, in the embodiment of the present application, since a certain amount of heat is generated during the charging process, once the temperature of the battery reaches an overheat threshold, the overheat protection of the mobile phone is triggered, the system automatically limits the charging speed of the mobile phone, and reduces the charging current to reduce the speed of generating heat during the charging process of the mobile phone. Therefore, in the charging state, the higher the temperature is, the smaller the charging reference current should be, and the temperature and the charging reference current are in an inverse proportional relation; and during discharging, the larger the power consumption of the current working scene is, the larger the required current value is.
Further, in the embodiment of the application, after the electric quantity detection device determines the preset reference current corresponding to the current state, it may further determine whether the electric quantity detection is abnormal according to the real-time current of the battery, that is, the detected actual charging/discharging current, and the preset reference current, that is, the ideal charging/discharging current.
Optionally, the battery detection device may calculate a difference between the real-time current and a preset reference current, and if the difference is within a preset difference range, it is determined that there is no abnormality in the electric quantity detection; and if the difference is not within the preset difference range, judging that the electric quantity detection is abnormal.
Specifically, in the charging state, the electric quantity detection device may calculate a difference between an actual charging current and an ideal charging current at a real-time temperature, and if the charging current difference is within a preset difference range, it is determined that no abnormality exists in electric quantity detection; and if the charging current difference value is not within the preset difference value range, determining that the power detection is abnormal. In the discharging state, the electric quantity detection equipment can calculate the difference value between the actual discharging current and the ideal discharging current in the current working scene, and if the difference value of the discharging current is within the range of the preset difference value, the electric quantity detection is determined to be not abnormal; and if the discharge current difference value is not within the preset difference value range, determining that the electric quantity detection is abnormal.
For example, when the current state is a charging state, the normal charging temperature range of the lithium battery of the mobile phone is 0-45 ℃, and assuming that the real-time temperature of the battery is 15 ℃, the ideal charging current is 50mA, the preset difference range is (-5mA, +5mA), if the actual charging current is 48mA, the difference between the actual charging current and the ideal charging current is-2 mA, and the preset difference range is met, the electric quantity detection is normal; and if the actual charging current is 30mA, the difference value between the actual charging current and the ideal charging current is-20 mA, and the preset difference value range is not met, the fact that the electric quantity detection is abnormal is indicated. Similarly, in the discharging state, if the difference value of the detected actual discharging current and the ideal discharging current corresponding to the current working scene is within the preset range, the electric quantity detection is normal, otherwise, the electric quantity monitoring is abnormal.
Further, in the embodiment of the application, after the electric quantity detection device determines the preset reference current corresponding to the current state and determines the electric quantity detection condition according to the real-time current and the preset reference current, the electric quantity detection device may further execute different processing procedures according to different electric quantity detection conditions; the electric quantity detection condition comprises that the electric quantity detection is abnormal and the electric quantity detection is not abnormal.
And 103, acquiring a voltage change parameter of the battery if the electric quantity detection is judged to be abnormal.
In the embodiment of the application, after the electric quantity detection device determines the preset reference current corresponding to the current state and judges whether the electric quantity detection is abnormal according to the real-time current and the preset reference current, if the electric quantity detection is judged to be abnormal, the electric quantity detection device can further obtain the voltage change parameter of the battery.
It should be noted that, in the embodiment of the present application, if it is determined that there is an abnormality in the power detection, it indicates that there may be a fault in the current sampling circuit, so that the detected real-time current value of the battery is no longer the actual charge/discharge current in the charge/discharge state, and it is understood that the current available power displayed by the power detection device is not the actual available power of the battery at this time, in this case, the power detection device may obtain the voltage variation parameter of the battery, so as to determine the actual available power of the battery through the voltage variation parameter.
Optionally, the electric quantity detection device may set a flag bit correspondingly after it is determined that the electric quantity detection is abnormal, and start an electric quantity detection abnormality error correction mechanism, at this time, the electric quantity detection device may obtain a voltage variation parameter of the battery, so as to determine an actual available electric quantity of the battery through the voltage variation parameter, thereby implementing correction processing on the display electric quantity of the electric quantity detection device.
It should be noted that, in the embodiment of the present application, the voltage variation parameter is used to characterize the open-circuit voltage variation value of the battery in the preset charge detection period. Specifically, the electric quantity detection device is provided with an electric quantity detection period, the electric quantity detection device can acquire the terminal voltage of the battery in real time in the actual use process of the battery, the terminal voltage is used as the real-time open-circuit voltage of the battery, and when the preset electric quantity detection period is met, the open-circuit voltage change value of the battery in the preset time period is calculated. For example, in the charging state, the open circuit voltage of the battery is 3.3V at time T, and the open circuit voltage of the battery is 3.8V at time T + T, so that the open circuit voltage of the battery changes by +0.5V in the preset charge detection period T.
Further, in the embodiment of the application, after the electric quantity detection device determines that the current electric quantity detection is abnormal and acquires the voltage change parameter of the battery, the electric quantity change prediction value of the battery may be further determined according to the voltage change parameter and the preset reference current in the current state.
And step 104, determining an electric quantity change predicted value of the battery according to the voltage change parameter and the preset reference current so as to finish electric quantity detection.
In the embodiment of the application, after the electric quantity detection device determines that the current electric quantity detection is abnormal and acquires the voltage change parameter of the battery, the electric quantity detection device may further determine the electric quantity change prediction value of the battery according to the voltage change parameter and the preset reference current so as to complete the electric quantity detection.
It should be noted that, in the embodiment of the present application, the power detection apparatus may estimate the predicted power change value of the battery by using the voltage change parameter of the battery, so as to obtain the first predicted change value of the battery power. Specifically, the electric quantity detection device can preset the corresponding relation between the open-circuit voltage variation value and the battery electric quantity variation value, so that after the electric quantity variation parameter of the battery is determined, a first predicted variation value of the battery electric quantity can be determined according to the electric quantity variation parameter, the corresponding relation between the preset open-circuit voltage variation value and the battery electric quantity variation value.
More specifically, because the battery is in the actual use process, the temperature change greatly affects the charge-discharge speed of the battery, thereby affecting the electric quantity change of the battery, therefore, the electric quantity detection device can also obtain the real-time temperature of the battery in the actual use process of the battery, and calculate the temperature change value of the battery in the preset electric quantity detection period, namely the temperature change parameter of the battery, and further determine the first predicted change value of the electric quantity of the battery according to the voltage change parameter of the battery, the temperature change parameter, the preset open-circuit voltage change value, and the corresponding relationship between the temperature change value and the electric quantity change value of the battery.
Further, in order to determine the actual electric quantity change of the battery more accurately, while estimating the electric quantity change of the battery according to the voltage change parameter, the electric quantity detection device may estimate the electric quantity change of the battery according to a preset reference current, and obtain a second predicted change value of the electric quantity of the battery, and further determine an electric quantity change predicted value of the battery according to the first predicted change value and the second predicted change value, that is, the actual electric quantity change of the battery in a preset detection period.
Specifically, according to step 102, it can be seen that there is a difference in the manner of determining the preset reference current in the charge/discharge state; wherein the reference current is determined based on the temperature in the charging state and the reference current is determined based on the working scenario in the discharging state. Therefore, in the charging state, the electric quantity detection device can acquire the reference current corresponding to the real-time temperature, and further determine a second predicted change value of the electric quantity of the battery based on the reference current corresponding to the real-time temperature; in the discharging state, the electric quantity detection device may obtain a reference current corresponding to the current working scene, and further determine a second predicted change value of the battery electric quantity based on the reference current corresponding to the current working scene.
Optionally, in the charging state, the electric quantity detection device may determine a plurality of reference current values corresponding to a plurality of groups of temperatures in the preset electric quantity detection period, and the electric quantity detection device may perform an integration operation on the plurality of reference current values (ideal charging currents) based on the preset detection period, so as to determine a second predicted change value of the electric quantity of the battery; during the discharging state, the electric quantity detection device can determine a plurality of reference current values corresponding to a plurality of working scenes in the preset electric quantity detection period, and the electric quantity detection device can perform integral operation on the plurality of reference current values (ideal discharging current) based on the preset detection period so as to determine a second predicted change value of the electric quantity of the battery.
It should be noted that, in the embodiment of the present application, when the charging device is used to charge the battery, since part of the electric quantity is dissipated in the form of heat, the current cannot be converted into the battery electric quantity by one hundred percent, and therefore, when the battery electric quantity change is estimated by presetting the reference current, the electric quantity detection device may determine the effective current according to the conversion rate of the current, that is, the charging current really obtained by the battery, and then perform the integral operation on the effective current, thereby determining the more accurate battery electric quantity change value.
Further, in the embodiment of the present application, the electric quantity detection device may determine the electric quantity variation prediction value of the battery jointly by combining a first predicted variation value of the electric quantity of the battery determined according to the open-circuit voltage variation and a second predicted variation value of the electric quantity determined according to the preset reference current corresponding to different states.
Specifically, in the embodiment of the present application, the electric quantity detection device may set an electric quantity update period, that is, calculate the electric quantity change prediction value of the battery once at a certain time interval, and in the electric quantity update period, the electric quantity detection device may detect the change of the electric quantity of the battery for multiple times in a preset electric quantity detection period, determine multiple groups of first prediction change values and second prediction change values, and then determine the electric quantity change prediction value of the battery according to the multiple groups of first prediction change values and second prediction change values.
Optionally, the electric quantity detection device may calculate an arithmetic average of the plurality of groups of first predicted variation values and second predicted variation values to obtain an electric quantity variation average, and use the electric quantity variation average as the electric quantity variation predicted value of the battery in the update period; the electric quantity detection equipment can also calculate the weighted average value of the plurality of groups of first prediction change values and second prediction change values, obtain the electric quantity change average value and use the electric quantity change average value as the electric quantity change prediction value of the battery.
Further, in an embodiment of the present application, fig. 2 is a schematic view illustrating an implementation flow of a power detection method according to an embodiment of the present application, and as shown in fig. 2, after determining whether there is an abnormality in power detection according to a real-time current and a preset reference current, if it is determined that there is no abnormality in power detection, a predicted value of power change of a battery is determined according to the real-time current (step 105). That is to say, if the electric quantity detection device determines that the electric quantity detection is not abnormal according to the real-time current and the preset reference current corresponding to the current state, it indicates that the current sampling circuit is good, so that the detected real-time current of the battery is the actual charging/discharging current in the charging/discharging state, and it can be understood that the current available electric quantity displayed by the electric quantity detection device is the actual available electric quantity of the battery at the moment. It should be noted that, if the power detection is normal, the power detection device does not need to set the corresponding flag bit, that is, it is not necessary to start the power detection abnormal error correction mechanism.
Further, in the embodiment of the application, the electric quantity detection device can monitor the electric quantity detection condition of the battery, and if the electric quantity detection is normal, the electric quantity change prediction value of the battery is determined according to the real-time current of the battery; and if the electric quantity detection is abnormal, the electric quantity detection equipment starts an electric quantity error correction mechanism, and further determines the electric quantity change predicted value of the battery by combining the voltage change parameter of the battery and the preset reference current.
The embodiment of the application provides an electric quantity detection method, and the electric quantity detection equipment can detect the current state and the real-time current of a battery; determining a preset reference current corresponding to the current state, and judging whether the electric quantity detection is abnormal or not according to the real-time current and the preset reference current; if the electric quantity detection is judged to be abnormal, acquiring a voltage change parameter of the battery; and determining the predicted value of the electric quantity change of the battery according to the voltage change parameter and the preset reference current so as to finish electric quantity detection. That is to say, in the embodiment of this application, electric quantity detection equipment can judge whether electric quantity detection has an abnormality according to the real-time current of battery to and the preset reference current that current state corresponds, then when judging that electric quantity detection has an abnormality, further based on the voltage variation parameter of battery and the preset reference current that current state corresponds, determines the electric quantity change predicted value of battery, and then can accurately obtain the actual electric quantity change of battery, further improved electric quantity detection's accuracy.
Based on the foregoing embodiment, in another embodiment of the present application, fig. 3 is a third schematic flow chart of an implementation of the electric quantity detection method provided in the embodiment of the present application, and as shown in fig. 3, after determining the electric quantity variation predicted value of the battery, that is, after step 104 or step 105, the step of the electric quantity detection apparatus executing the electric quantity detection method may further include:
and 106, acquiring the current available electric quantity of the battery.
In the embodiment of the application, the electric quantity detection device may obtain the current available electric quantity of the battery first after determining the electric quantity change prediction value of the battery.
It should be noted that, in the embodiment of the present application, the electric quantity detection device may determine the current available electric quantity of the battery based on the electric quantity currently displayed in the electric quantity display area of a certain electronic device, where the available electric quantity is an available electric quantity before the completion of the charge/discharge of the battery, that is, before the update of the electric quantity of the battery at this time. Specifically, because the update speed of the display electric quantity of the electronic equipment is slower than the actual capacity change of the battery, when the electric quantity change predicted value of the battery is calculated, the electric quantity displayed by the electronic equipment is not updated, so that the current available electric quantity of the battery can be determined according to the display electric quantity, and the electric quantity is used as the available electric quantity before the current battery electric quantity is updated.
Optionally, when the electric quantity detection device determines the current available electric quantity according to the display electric quantity, if the display area displays the electric quantity in a percentage manner, the electric quantity detection device may obtain the full electric quantity of the battery, that is, the battery capacity when the battery is fully charged, and the current available electric quantity may be determined by multiplying the full electric quantity of the battery by the percentage occupied by the current available electric quantity. For example, the full charge of the mobile phone is 1000mAh, and if the mobile phone currently displays a charge of 60, it can be determined that the current available charge of the battery is sixty percent of the full charge, i.e., the current available charge is 600 mAh.
Further, in the embodiment of the application, after the electric quantity detection device obtains the current available electric quantity of the battery, the actual available electric quantity of the battery can be further determined according to the current available electric quantity, the current state and the determined electric quantity change prediction value.
And step 107, determining the actual available electric quantity of the battery according to the current available electric quantity, the current state and the electric quantity change predicted value.
In the embodiment of the application, after the electric quantity detection device acquires the current available electric quantity of the battery, the actual available electric quantity of the battery can be further determined by using the current available electric quantity and combining the current state and the determined electric quantity change predicted value.
Specifically, in the embodiment of the application, if the current state is the charging state, the current available electric quantity is subjected to superposition processing according to the electric quantity change prediction value to obtain the actual available electric quantity; that is, if the current state of the battery is a charging state, since the electric quantity of the battery can be increased by charging, the electric quantity change prediction value of the battery is an electric quantity change value increased by charging, and the electric quantity detection device needs to add the current available electric quantity and the electric quantity change prediction value on the basis of the current available electric quantity to obtain the actual available electric quantity of the battery, that is, the actual available electric quantity of the battery after the electric quantity is updated.
