Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the power prompting method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the power prompting method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal device can implement the power prompting method provided by the embodiment of the invention by running the software program in the android operating system.
The first embodiment:
the following describes an electric quantity prompting method according to an embodiment of the present invention with reference to fig. 2. As shown in fig. 2, the method includes S201 to S204:
s201, in the process of charging the battery of the terminal device, the terminal device detects the current residual electric quantity value of the battery.
In the embodiment of the invention, the terminal device may detect the current remaining capacity value of the battery through a coulomb meter detection method. Wherein the current remaining electric quantity value of the battery can be expressed by coulomb (unit: ampere hour/ampere second). Generally, the remaining capacity displayed in the terminal device is displayed in percentage form for the convenience of the user to view, and for example, the current remaining capacity value is a current remaining capacity value percentage, that is, a ratio between the remaining capacity of the battery and the capacity of the battery.
S202, the terminal equipment determines the current charging voltage value of the battery according to the detected current residual electric quantity value.
Optionally, the above S202 may be implemented by at least the following two display modes:
a first possible implementation:
in this embodiment of the present invention, S202 specifically includes the following steps:
s202a1, the terminal device determines a target open-circuit voltage value corresponding to the current residual current value from the first corresponding relationship.
Here, the Open Circuit Voltage (OCV) is a terminal voltage of the battery in an Open circuit state and is referred to as an Open circuit voltage, and a charging voltage of the battery can be calculated from the Open circuit voltage. The first corresponding relationship is a mapping relationship between the remaining capacity and the open-circuit voltage, and the corresponding relationship includes a mapping relationship between a current remaining capacity value and a target open-circuit voltage value. For example, the first corresponding relationship may be an open-circuit voltage table, where the open-circuit voltage table includes at least one open-circuit voltage value and at least one remaining power value, one open-circuit voltage value corresponds to one remaining power value, and the terminal device uses the current remaining power value as an index to find a target open-circuit voltage value corresponding to the current remaining power value from the open-circuit voltage table.
And S202a2, the terminal equipment calculates the current charging voltage value of the battery according to the target open-circuit voltage value and the preset charging cut-off current value.
In the embodiment of the present invention, the charging voltage may be calculated by the following formula 1.
Charging voltage OCV + charging cutoff current equivalent impedance of battery (formula 1)
For the terminal device, the battery equivalent impedance and the charging cutoff current are hardware parameters of the terminal device, and different terminal devices correspond to different charging cutoff currents. Typically, the off-charge current is a constant value (e.g., 250mA (millivolts)), which may also be referred to as the maximum charge current, and when the charge current of the battery reaches the off-charge current, it indicates that the battery is fully charged. The battery equivalent impedance is mainly related to temperature, and the battery equivalent impedance is different under different temperature scenes.
In one example, embodiments of the present invention may only consider the equivalent impedance of the battery at normal temperature (e.g., 25 degrees). For example, assuming that the battery equivalent impedance is 78 milliohms and the current OCV is 4320mV, the corresponding charging voltage. Therefore, the estimated charge cut-off voltage value was estimated to be 4320+250 × 78/1000 — 4339.5mV, and after rounding, 4339mV was taken as the current charge voltage value.
Further optionally, before S202a1, the method further includes the following steps:
step 1: the terminal equipment acquires the current temperature value of the battery.
Step 2: and the terminal equipment searches out a first corresponding relation corresponding to the current temperature value from the at least one corresponding relation.
Wherein, at least one corresponding relation comprises a first corresponding relation, and each corresponding relation corresponds to a temperature value.
Illustratively, the terminal device is internally provided with a temperature sensor for detecting the temperature of the battery of the terminal device, and the corresponding relation corresponding to the current temperature value is found out from at least one corresponding relation by taking the current temperature value of the battery as an index.
In a second possible implementation:
in this embodiment of the present invention, S202 specifically includes the following steps:
s202b, the terminal device determines a current charging voltage value corresponding to the current remaining electric quantity value from the second corresponding relationship.
The second mapping relationship is a mapping relationship between the remaining capacity and the charging voltage, and the mapping relationship includes a mapping relationship between a current remaining capacity value and a current charging voltage value. For example, the second corresponding relationship may be a charging voltage table, where the charging voltage table includes at least one charging voltage value and at least one remaining power value, one charging voltage value corresponds to one remaining power value, and the terminal device searches the charging voltage value corresponding to the current remaining power value from the charging voltage table by using the current remaining power value as an index. For example, the charging voltage value calculation process in the charging voltage meter may refer to the charging voltage value calculation process, which is not described herein again.
And S203, the terminal equipment calculates the residual electric quantity to be displayed according to the charge cut-off voltage value, the current charge voltage value and the current residual electric quantity value.
For the terminal device, the charging cut-off voltage value is a hardware parameter of the terminal device, and different terminal devices correspond to different charging cut-off voltage values. Generally, the charge cut-off current value is a constant value (e.g., 4.37V (volts)), which may also be referred to as a maximum charge voltage, and when the charge voltage value of the battery reaches the charge cut-off current value, it indicates that the battery is fully charged.
Optionally, the terminal device may measure a current charging progress based on a difference between the charging cut-off voltage value and the current charging voltage value, and determine the remaining power to be displayed finally based on the difference.
In the embodiment of the present invention, S203 specifically includes the following steps:
and S203a, the terminal equipment determines a charging voltage error coefficient according to the difference value between the charging cut-off voltage value and the current charging voltage value.
And S203b, weighting the charging voltage error coefficient and the current residual electric quantity value by the terminal equipment to obtain the residual electric quantity to be displayed.
Further optionally, S203a specifically includes the following steps:
s203a1, the terminal device obtains the difference value M between the charging cut-off voltage value and the current charging voltage value.
And S203a2, the terminal equipment determines a charging voltage error coefficient N according to the difference value M and a preset formula.
In one example, the preset formula is:
k is a constant value. Generally, the value of K is related to the accuracy of the difference, for example, K is usually 100 if the unit of the charge cut-off voltage value and the current charge voltage value is V, and K is 0.1 if the unit of the charge cut-off voltage value and the current charge voltage value is mV.
For example, assuming that the charge cut-off voltage value V1 of the terminal device is 4370mV, the estimated current charge voltage value V2 is 4339mV, the error is V1-V2-31 mV, M k-31-0.1-3.1, 3.1 is rounded to 3, 3 is substituted into the above formula 2,
in one example, the preset formula is as follows:
wherein k is a constant. In general, the value of K is related to the accuracy of the difference, for example, K is usually 100 if the unit of the charge cut-off voltage value and the current charge voltage value is V (volt), and K is 0.1 if the unit of the charge cut-off voltage value and the current charge voltage value is mV (millivolt).
For example, assuming that the charge cut-off voltage value V1 of the terminal device is 4370mV, the estimated current charge voltage value V2 is 4339mV, the error is V1-V2-31 mV, 31 x 0.1-3.1 mV, 3.1 is rounded to 3, 3 is substituted into the above formula 2,
for example, assume that the current remaining charge value of the terminal device is 95%, and the charging voltage error coefficient is
The corresponding remaining capacity to be displayed
And S204, the terminal equipment displays the residual electric quantity to be displayed on a display interface of the terminal equipment.
According to the electric quantity display method provided by the embodiment of the invention, the terminal equipment detects the current residual electric quantity value of the battery in the battery charging process, so that the current charging voltage value of the battery can be determined according to the detected current residual electric quantity value, and then the current residual electric quantity to be displayed in the interface of the terminal equipment is calculated by combining the current charging voltage value, the charging cut-off voltage value and the current residual electric quantity value. Therefore, in the process of charging the battery, the terminal equipment monitors the current charging voltage value of the battery, so that the calculated residual capacity to be displayed considers the current charging voltage value and the charging cut-off voltage value, the increase of the residual capacity displayed in the terminal equipment can be delayed under the condition that the battery is about to be fully charged, finally, the charging cut-off time point of the battery is synchronized with the display of 100% of the residual capacity of the battery, and the problem that the residual capacity is displayed in advance by the terminal equipment to be 100% when the charging voltage of the battery does not reach the charging cut-off voltage value is solved.
