Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, 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, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides a method for displaying battery power, which can be applied to hardware equipment, or a software application program, or a server. The specific implementation of the method is as shown in fig. 1:
The preset voltage is a critical voltage used for distinguishing two adjacent electric quantity grades, and the operation modes comprise a normal operation mode and a low-power-consumption operation mode.
Specifically, the principle of collecting the battery power is introduced: after the battery voltage is obtained, a calculation result corresponding to the battery voltage is obtained by calculation using a formula DAC _ VAL/64 × VBAT, and a relationship between the calculation result and a reference voltage is compared by a voltage comparator, and the calculation result is defined as a calculation voltage for convenience of description. And when the calculation voltage is greater than the reference voltage, outputting a high level, and when the calculation voltage is less than the reference voltage, outputting a low level, and determining the electric quantity grade by using the output high level and the output low level, wherein different electric quantity grades correspond to different battery electric quantities. Of course, the user may also correspond different power levels to the same battery power, that is, the user may set the corresponding relationship between the power levels and the battery power according to actual needs. Wherein, the reference voltage is represented by VREF, the battery voltage is represented by VBAT, the calculation voltage is represented by VT, and DAC _ VAL is a 6-bit digital-analog coding value corresponding to the preset voltage.
The following description will be made by taking the battery voltage of an air conditioner remote controller as an example, wherein the remote controller uses two dry batteries connected in series, the battery voltage is 1.5V × 2 — 3V, and the battery capacity changes when the battery changes by 0.1V in the actual use process. In this embodiment, VREF is 0.8V, and 3V is divided into 4 parts, some of which are described below:
first, when the current circuit filter function is designed, the anti-jitter function near the critical point is limited, so that the battery voltage jitters at the critical point, which cannot be avoided. To address this problem, various critical points of the battery voltage are found, which are defined as a preset voltage in the present application. For example, the preset voltages include: 2.69V, 2.56V, 2.327V, 2.226V and 2.048V.
The following equations are used:
VT＝DAC_VAL/64*VBAT
DAC _ VAL is calculated.
Because preset voltage belongs to battery voltage, for the critical voltage who is used for distinguishing two adjacent electric quantity grades, and, through the preset voltage who calculates being VREF, so with the battery voltage value for preset voltage, with VT value for VREF 0.8V, bring into in the formula:
0.8＝DAC_VAL/64*2.69
0.8＝DAC_VAL/64*2.56
0.8＝DAC_VAL/64*2.327
0.8＝DAC_VAL/64*2.226
0.8＝DAC_VAL/64*2.048
respectively obtaining:
DAC_VAL＝19
DAC_VAL＝20
DAC_VAL＝22
DAC_VAL＝23
DAC_VAL＝25
next, the detection process of the battery power is divided into 8 stages according to the value of DAC _ VAL, as shown in tables 1, 2, and 3:
| BV | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | Display | Level |
| >2.69V | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 3grids | 0xff |
| >2.56V | 0 | 1 | 1 | 1 | 1 | 1 | 1 | 1 | 3grids | 0xfe |
| >2.327V | 0 | 0 | 1 | 1 | 1 | 1 | 1 | 0 | 2grids | 0x7c |
| >2.226V | 0 | 0 | 0 | 1 | 1 | 1 | 0 | 0 | 1grids | 0x38 |
| >2.048V | 0 | 0 | 0 | 0 | 1 | 0 | 0 | 0 | 0grids | 0x10 |
| <2.048V | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0 | 0grids | 0x00 |
TABLE 1 data schematic diagram of battery power up-down power level display
Wherein BV is an abbreviation of Battery Voltage and represents a preset voltage, Display represents the number of Display grids of battery electric quantity, Level represents electric quantity Level, and numbers 1-8 of a transverse header respectively represent that:
1 corresponds to the first Phase 1: DAC _ VAL1 ═ 19;
2 corresponds to the second Phase 2: DAC _ VAL2 ═ 20;
3 corresponds to the third Phase 3: DAC _ VAL3 ═ 22;
4 corresponds to the fourth Phase 4: DAC _ VAL4 ═ 23;
5 corresponds to the fifth Phase 5: DAC _ VAL5 ═ 25;
6 corresponds to the sixth Phase 6: DAC _ VAL6 ═ 23;
7 corresponds to the seventh Phase 7: DAC _ VAL7 ═ 22;
8 corresponds to the eighth Phase 8: DAC _ VAL8 is 20.
Specifically, the preset voltages are 2.69V and 2.56V for example:
taking the acquired battery voltage as 2.8V as an example, performing training comparison on the 8 stages, as shown in fig. 2, in order to save chip power consumption, a low power consumption operation mode is adopted when battery voltage detection is performed, when the low power consumption operation mode detects that the level of electric quantity changes, a normal operation mode is started, at this time, whether electric quantity jump occurs is judged, when the electric quantity jump is determined, the 8 stages are sequentially compared, and the position of the training value for performing training comparison is: the first detection is placed at the lower position and the second detection is placed at the upper position, namely, the value obtained in the first stage of the first detection is placed at the position of the eighth stage, and the value obtained in the eighth stage of the second detection is placed at the position of the first stage. And finally, determining the electric quantity grade according to the obtained round training value. And the placing position of the round training value is opposite to the numerical sequence of the binary representation of the level.
Next, the DAC _ VAL values corresponding to 2.8V and 8 stages are sequentially substituted into the above formula by calculating according to the above formula, and the obtained VTs are:
VT＝DAC_VAL/64*2.69＝19/64*2.8＝0.831
VT＝DAC_VAL/64*2.56＝20/64*2.8＝0.875
from the above formula, it can be seen that when the VT is greater than VREF at DAC _ VAL of 19 and 20, the VT corresponding to the calculation results of other phases must also be greater than VREF. Also, since a high level is output when VT is greater than VREF, the values corresponding to these eight phases are all 1. By adopting a 16-system mode, the 11111111 is converted into the 16-system of 0xff, that is, the electric quantity level corresponding to the preset voltage of 2.69V can be determined to be 0 xff.
Next, taking the acquired battery voltage as 2.6V as an example, performing round training comparison on the 8 stages, and sequentially substituting DAC _ VAL values corresponding to 2.6V and 8 stages into the above formula, where the obtained VTs are:
VT＝DAC_VAL/64*2.69＝19/64*2.6＝0.772
VT＝DAC_VAL/64*2.56＝20/64*2.6＝0.813
VT＝DAC_VAL/64*2.56＝22/64*2.6＝0.894
VT＝DAC_VAL/64*2.56＝23/64*2.6＝0.934
from the above formula, it can be seen that VT is less than VREF when DAC _ VAL is 19, low is output, VT is greater than VREF when DAC _ VAL is 20, 22, 23, high is output, and VT corresponding to other remaining stage calculation results can certainly be greater than VREF. Therefore, the eight stages correspond to a value of 01111111, and 11111110 is converted into a value of 0xfe in 16, that is, the preset voltage of 2.56V can be determined to correspond to a power level of 0 xfe.
According to the method, by analogy, the electric quantity grade corresponding to the preset voltage 2.327V is determined to be 0x7c, the electric quantity grade corresponding to the preset voltage 2.226V is determined to be 0x38, the electric quantity grade corresponding to the preset voltage 2.048V is determined to be 0x10, and when the battery voltage is lower than the preset voltage 2.048V, the electric quantity grade corresponding to the battery voltage is determined to be 0x 00.
| BV | 1 | 2 | 3 | 4 | Display | Level |
| >2.69V | 1 | 1 | 1 | 1 | 3grids | 0xf |
| >2.56V | 0 | 1 | 1 | 1 | 3grids | 0xe |
| >2.327V | 0 | 0 | 1 | 1 | 2grids | 0xc |

TABLE 3 data diagram for battery power reduction power level display
In one embodiment, comparing the battery voltage with a preset voltage corresponding to the current operation mode includes: and comparing first coded data corresponding to the acquired battery voltage with second coded data corresponding to a preset voltage corresponding to the current operation mode, wherein the first coded data are obtained by calculating the battery voltage and a reference voltage, and the second coded data are obtained by calculating the preset voltage and the reference voltage.
Specifically, the battery state includes: the battery state of the battery discharging process is a discharging state, and the battery state of the battery charging process is a charging state. The stage operation corresponding to the discharging process is called an upshift process, for example, the preset voltage corresponding to <19, 20, 22, 23> is <2.69V, 2.56V, 2.327V, 2.226V >; the operation of the corresponding stage of the charging process is called a downshift process, for example, the preset voltage corresponding to <25, 23, 22, 20> is <2.048V, 2.226V, 2.327V, 2.56V >, wherein each stage of the upshift process or the downshift process is called a gear, in the downshift process, when four gears are all effective, the battery level display is full, when one gear is ineffective, the battery level display is reduced by one, and the like; in the upshifting process, when four gears are invalid, the battery electric quantity display zero grid is represented, when one gear is valid, the battery electric quantity display is increased by one grid, and the like. Due to the hysteresis effect of hardware, after the upshifting processing or the downshifting processing of the method is adopted, the bidirectional hysteresis effect can be realized, and the determination of the electric quantity grade is more accurate when the electric quantity jumps.
And 102, if the two continuous comparison results are different, determining the jump of the generated electric quantity, and counting the times of the jump of the generated electric quantity.
Specifically, in order to reduce chip power consumption and prolong the service life of a battery, two sets of operation modes are designed, one set of operation modes is a normal operation mode, the other set of operation modes is a low-power consumption operation mode, wherein reference voltages of the two sets of operation modes are inconsistent, and therefore preset voltages of the two sets of operation modes are inconsistent. In the practical application process, in order to save the power consumption of the chip, the battery voltage is detected in a low-power-consumption operation mode, the chip is awakened when the low-power-consumption operation mode detects that the electric quantity level changes, the normal operation mode detection is started, the normal operation mode and the low-power-consumption operation mode are alternately switched and detected, and the chip is awakened back and forth. The comparison results are different because the detection results of the two operation modes are different, and if the comparison results of two consecutive times are different, the occurrence of electric quantity jump is determined, and the times of the occurrence of the electric quantity jump are counted.
And 103, when the times reach a preset value, selecting one of two adjacent electric quantity grades as a final electric quantity grade.
Specifically, when the number of times of power jump reaches a preset value, one power level is selected from two adjacent power levels, and it can be effectively determined that the power jump is caused by the alternate detection of a normal operation mode and a low power consumption operation mode and the chip is waken up back and forth, rather than the accidental power jump caused by external factors or self factors.
In a specific embodiment, when the number of times of power hopping reaches a preset value, the current battery state is determined to be a charging state, and a power level higher than the current battery state in two adjacent power levels is selected as a final power level, wherein the power levels are in a direct proportion relation with the power of the battery.
In a specific embodiment, when the number of times of electric quantity jump reaches a preset value, the current battery state is determined to be a discharge state, and an electric quantity level which is lower than the electric quantity levels in two adjacent electric quantity levels is selected as a final electric quantity level, wherein the electric quantity level and the electric quantity of the battery are in a direct proportion relation.
Specifically, the battery state is a discharge state, and when the electric quantity jumps, the downshift process is performed, as shown in fig. 3, the downshift process is performed at <25, 23, 22, 20>, and the downshift process is described by taking 2.6V as an example:
and judging whether the current gear is equal to the previous gear, judging whether the jumping frequency reaches a preset value if the current gear is equal to the previous gear, judging whether the level is equal to 0x7 if the jumping frequency reaches the preset value, and displaying the level corresponding to the current gear if the level does not reach the preset value. The situation can hardly occur, and no unexpected fault occurs and no electric quantity jump occurs when the current gear is equal to the previous gear. And if the current gear is not equal to the previous gear, counting the jumping times, judging whether the jumping times reach a preset value, if so, judging whether the level is equal to 0x7, and if not, displaying the level corresponding to the current gear.
Judging whether the level is equal to 0x7, if so, setting <25, 23, 22, 20> to <25, 23, 22, 0>, namely setting the gear of 20 as invalid, and judging whether the level is equal to 0x 3; if the level is not equal to 0x7, determine whether the level is equal to 0x 3.
And comparing the obtained result with each gear according to the process in a analogized mode to obtain a comparison result, and obtaining the battery electric quantity to be displayed according to the obtained comparison result.
In a specific embodiment, a criterion may be set, and when the number of times of the electric quantity jump reaches a preset value, selecting an electric quantity level corresponding to a preset voltage corresponding to the normal operation mode as a final electric quantity level criterion is performed. Of course, the standard user may set according to an actual situation, and set that when the electric quantity jumps and reaches a preset value at this time, the electric quantity grade corresponding to the preset voltage corresponding to the low power consumption operation mode is selected as a standard of the final electric quantity grade.
And 104, displaying according to the battery electric quantity corresponding to the final electric quantity grade.
In one embodiment, the reference voltage corresponding to the normal operation mode is not equal to the reference voltage corresponding to the low power consumption operation mode, so that the preset voltage corresponding to the normal operation mode is not equal to the preset voltage corresponding to the low power consumption operation mode. The VBAT can be obtained by the above formula VT — DAC _ VAL/64 — VBAT, for example, substituting the reference voltage 0.8V corresponding to the normal operation mode and the value of DAC _ VAL of 19 into the formula to obtain VBAT equal to 2.69V; and substituting the reference voltage 0.7V corresponding to the low-power-consumption operation mode and the DAC _ VAL value 19 into a formula to obtain that VBAT is equal to 2.358V, so that the preset voltage corresponding to the normal operation mode can be obtained and is not equal to the preset voltage corresponding to the low-power-consumption operation mode. VBAT at this time is the threshold voltage of two adjacent power levels.
In addition, as can be seen from fig. 4, each preset voltage should have only one line, but actually corresponds to two lines, wherein a solid line LP _ VREF represents a preset voltage in the normal operation mode, a dashed line Nor _ VREF represents a preset voltage in the low power consumption operation mode, and a slash VBAT where the solid line LP _ VREF intersects with the dashed line Nor _ VREF represents a battery voltage, the battery voltage VBAT drops as the battery discharges, and when the battery voltage VBAT is between the solid line LP _ VREF and the dashed line Nor _ VREF, the power levels detected in the normal operation mode and the low power consumption operation mode are inconsistent, which causes chip wake-up and power jump. In addition, the preset voltage is not a fixed value, and the error exists in a certain range of about plus or minus 30mV, so that 2.544V marked by the preset voltage value corresponding to the solid line LP _ VREF in fig. 4 is shown, and it is known from practical application that the difference between the preset voltage corresponding to the normal operation mode and the preset voltage corresponding to the low power consumption mode is about 6 mV.
In one embodiment, the preset voltage corresponding to the normal operation mode is smaller than the preset voltage corresponding to the low power consumption operation mode.
According to the method provided by the embodiment of the application, in the process of real-time voltage detection, after the battery voltage is obtained every time, the obtained battery voltage is compared with the preset voltage corresponding to the current operation mode to obtain a comparison result, wherein the preset voltage is a critical voltage used for distinguishing two adjacent electric quantity grades, the operation modes comprise a normal operation mode and a low-power-consumption operation mode, and by comparing the battery voltage with the preset voltage corresponding to the current operation mode, the magnitude relation between the battery voltage and the preset voltage corresponding to the normal operation mode and the magnitude relation between the battery voltage and the preset voltage corresponding to the low-power-consumption operation mode can be effectively obtained.
Further, when the two continuous comparison results are different, namely, the two magnitude relations are not consistent, the occurrence of electric quantity jump is determined, the number of times of the occurrence of electric quantity jump is counted, and the accidental electric quantity jump caused by external factors or self factors or the electric quantity jump when the battery voltage reaches the critical voltage of two adjacent electric quantity grades can be determined through the number of times of the electric quantity jump; when the number of times of electric quantity jumping reaches a preset value, determining that the battery voltage jumps when reaching the critical voltage of two adjacent electric quantity grades, and selecting one of the two adjacent electric quantity grades as a final electric quantity grade; and displaying the battery electric quantity corresponding to the final electric quantity grade.
The method effectively solves the problem that under the condition that the normal operation mode and the low-power-consumption operation mode are executed together, the battery power is jumped due to inconsistent power levels detected by the two modes when the battery voltage is between the critical value of the normal operation mode and the critical value of the low-power-consumption operation mode because the critical values of the two operation modes are different.
