Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, technical solutions between various embodiments may be combined with each other, but must be realized by a person skilled in the art, and when the technical solutions are contradictory or cannot be realized, such a combination should not be considered to exist, and is not within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides a method for updating battery capacity, which is applied to a device terminal, and includes:
s1: judging whether the current battery state is a preset starting state or not;
s2: if the starting state is preset, starting timing;
s3: in the timing process, monitoring whether the battery state reaches a preset end state in real time;
s4: if the preset ending state is reached, stopping timing, and counting the total electric quantity consumed by the battery in the timing process;
s5: and updating the battery capacity according to the sum of the electric quantity.
In the step S1 of determining whether the current battery status is the preset starting status, the user sets a starting status in the device in advance as a starting point for counting the power consumption of the battery, and in some embodiments, the preset starting status refers to a status where both conditions that the percentage of the power of the battery is 100% and the battery is not in the charging state are satisfied. Only when the percentage of the battery capacity is 100%, the battery capacity is taken as a starting point of the statistics, and the battery capacity consumption counted by updating the battery capacity data is accurate, so that a complete battery capacity data can be obtained. Only when the battery is not in a charging state, namely no external electric quantity is charged for the battery, the statistics of the consumption of the electric quantity of the battery is meaningful, otherwise, the electric quantity of the battery is replenished all the time while being consumed, the total consumption of the counted electric quantity of the battery is larger than the actual capacity of the battery, and the accurate capacity of the battery cannot be obtained. In some embodiments, whether the battery is being charged is determined by detecting whether the USB port is in an active state.
In step S2, if the above-mentioned state is the preset starting state, a timing is started when the percentage of battery power is detected to be 100% and the battery is not in the charging state, and a timing is started to record the time of the subsequent battery power consumption statistics for the subsequent calculation. The timing includes one or more timing cycles consisting of a predetermined time interval, and in some embodiments, the time interval of one timing cycle is set to 10s, i.e., each 10s goes from the previous timing cycle to the next timing cycle, and finally the whole timing process may include one or more timing cycles, i.e., one or more 10 s. The timing is performed by adopting the timing cycle, because in the process of battery power consumption, the battery power is not stably consumed at a certain rate, but is in continuous variation, that is, the current magnitude is continuously varied, the consumption rate at this moment may be completely different from the consumption rate at the next moment, the whole process from the battery power percentage consumption of 100% to the battery power percentage of 0% cannot calculate the power consumption through a uniform constant function, the power consumption can only be calculated by micro-integration according to the power calculation formula Q ═ I × t, and when the time t is sufficiently small, the current I can be regarded as a constant at this moment and is not varied. The current of one timing cycle corresponds to I in the calculation formula, and the time of one timing cycle corresponds to t in the calculation formula, so that the sum of the electric quantity consumed by the battery from 100% of the electric quantity to 0% of the electric quantity can be accurately obtained through the sum of the electric quantity consumed by a plurality of timing cycles.
In the above timing process, in step S3 of monitoring whether the battery status reaches the preset end status in real time, the user sets an end status in the device in advance as an end point of counting the power consumption of the battery, in some embodiments, the preset end status refers to that the battery power percentage is 0%, and there is no charging record from the beginning of timing to the detection that the battery power percentage is 0%. At this time, even if the percentage of battery charge is detected to be 0%, since the presence of the uncharged mark is detected, that is, the charging record exists between the time when the timing is started and the time when the percentage of battery charge is detected to be 0%, the power consumption data corresponding to the actual battery capacity cannot be counted, and the subsequent step of counting the total power consumed by the battery is not performed.
In the step S4 of stopping timing and counting the total amount of power consumed during the battery timing process if the preset end state is reached, if it is detected that the percentage of power of the battery is 0%, and no charging record exists from the start of timing to the detection that the percentage of power of the battery is 0%, it indicates that the battery has consumed from 100% to 0% and no external power is replenished midway, and the condition of calculating the capacity of the complete battery is satisfied, and the total amount of power consumed by the battery can be counted. In some embodiments, during the timing process, after each timing cycle is ended, the consumed electric quantities of each timing cycle are counted, and then the sum of the consumed electric quantities of all timing cycles before the current timing cycle is added to obtain a new sum of the consumed electric quantities. For example, after the timing is started and the first timing cycle is finished, the electric quantity consumed by the first timing cycle is counted, and the counted electric quantity consumed by the first timing cycle is recorded; after the second timing cycle is finished, counting the electric quantity consumed by the second timing cycle, adding the electric quantity consumed by the first timing cycle recorded before to obtain an electric quantity sum, recording the electric quantity sum, and then repeating the third timing cycle, the fourth timing cycle and the last timing cycle to obtain a final electric quantity sum. In other embodiments, after each timing cycle is finished, the amount of power consumed in the timing cycle is counted, the amount of power consumed in the timing cycles is recorded, and after the timing is stopped, the recorded amounts of power consumed in all timing cycles are summed to obtain a final total amount of power consumed.
In the above step S5 of updating the battery capacity according to the total amount of electricity, after counting the total amount of electricity consumed from 100% of the battery capacity to 0% of the battery capacity, the counted total amount of electricity is read and updated to the latest battery capacity. After the battery capacity is updated, the battery capacity recorded data is consistent with the actual data, and in the using process, the compatibility of the battery and the equipment is improved, and the using experience of the equipment is optimized.
As shown in fig. 2, in some embodiments, the step S1 of determining whether the current battery status is the preset starting status includes:
s11: judging whether the current electric quantity percentage of the battery is 100%;
s12: if the current state is 100%, judging whether the battery is in a charging state;
s13: and if the battery is not in the charging state, judging that the current battery state is a preset starting state.
In the step S11 of determining whether the current percentage of battery capacity is 100%, only when the battery capacity percentage is 100%, the battery capacity consumption counted by updating the battery capacity data is accurate as the starting point of the statistics, and a complete battery capacity data can be obtained from the battery capacity percentage of 100% to the battery capacity percentage of 0%.
In the step S12 of determining whether the battery is in a charging state if the current is 100%, in some embodiments, it is determined whether the battery is in a charging state by detecting whether the USB port is in an operating state, and it is meaningful to count the consumption of the battery power only when the battery is not in the charging state, i.e., no external power is supplied to charge the battery, otherwise the battery power is consumed and is replenished all the time, and the total amount of the counted battery power consumption is greater than the actual battery capacity, and an accurate battery capacity cannot be obtained.
In the step S13, if the battery is not in the charging state, the current battery state is determined to be the preset starting state, after the two determinations, that is, the preset starting state refers to a state where the percentage of battery power is 100% and both conditions that the battery is not in the charging state are satisfied, the state is used as the starting point of counting the battery power consumption, so as to update the battery capacity data.
As shown in fig. 3, in some embodiments, the step S3 of monitoring whether the battery status reaches the preset end status in real time includes:
s31: judging whether the percentage of the electric quantity of the battery is 0%;
s32: if yes, judging whether a charging record exists between the time of starting timing and the time corresponding to the time when the electric quantity is 0%;
s33: and if no charging record exists, judging that the corresponding battery state is a preset end state when the battery electric quantity percentage is 0%.
In the step S31 of determining whether the percentage of battery power is 0%, the battery power consumption counted as the updated battery capacity data is accurate only when the percentage of battery power is 0%, and a complete battery capacity data can be obtained from the battery power consumption of 100% to the battery power consumption of 0%.
In step S32, if the charging record exists between the time when the timer is started and the time corresponding to the amount of electricity being 0%, in some embodiments, an uncharged flag is set up when the timer is started when a preset starting state is detected, the battery is monitored in real time during the timer, and if the battery is detected to be in a charged state during the timer, the uncharged flag set up before the timer is covered by the chargeable flag, and the timer is stopped. At this time, even if the percentage of battery charge is detected to be 0%, since the presence of the uncharged mark is detected, that is, the charging record exists between the time when the timing is started and the time when the percentage of battery charge is detected to be 0%, the power consumption data corresponding to the actual battery capacity cannot be counted, and the subsequent step of counting the total power consumed by the battery is not performed.
In the step S33, if there is no charging record, it is determined that the corresponding battery status is the preset end status when the battery power percentage is 0%, that is, the preset end status refers to the status that there is no charging record from the beginning of timing to the detection that the battery power percentage is 0%, and this status is used as the end point of the statistical battery power consumption, so as to update the battery capacity data.
As shown in fig. 4, in some embodiments, the timing process includes a plurality of timing cycles, each timing cycle is composed of a preset time interval, and the step S4 of counting the total amount of power consumed by the battery includes:
s41: counting each electric quantity Q consumed by the battery in each timing cycle by the following formula:
q ═ I × t, where I is the current in the clocked cycle and t is the preset time interval;
s42: summing all the electric quantities consumed by the batteries in all the timing cycles to obtain the electric quantity sum;
s43: and recording the sum of the electric quantity.
Each amount of electricity Q consumed by the battery in each timing cycle is counted by the following formula: in step S41, where I is the current in the timing cycle and t is the preset time interval, when it is detected that the percentage of battery charge is 100% and the battery is not in a charged state, a timing is started and the subsequent battery charge consumption statistics are recorded for subsequent calculation. The timing includes one or more timing cycles consisting of a predetermined time interval, and in some embodiments, the time interval of one timing cycle is set to 10s, i.e., each 10s goes from the previous timing cycle to the next timing cycle, and finally the whole timing process may include one or more timing cycles, i.e., one or more 10 s. The timing is performed by adopting the timing cycle, because in the process of battery power consumption, the battery power is not stably consumed at a certain rate, but is in continuous variation, that is, the current magnitude is continuously varied, the consumption rate at this moment may be completely different from the consumption rate at the next moment, the whole process from the battery power percentage consumption of 100% to the battery power percentage of 0% cannot calculate the power consumption through a uniform constant function, the power consumption can only be calculated by micro-integration according to the power calculation formula Q ═ I × t, and when the time t is sufficiently small, the current I can be regarded as a constant at this moment and is not varied. The current in one timing cycle corresponds to I in the calculation formula, and the time of one timing cycle corresponds to t in the calculation formula, so that the sum of the electric quantity consumed by the battery from 100% to 0% can be accurately obtained through the sum of the electric quantity consumed by a plurality of timing cycles.
In the step S42 of summing the electric quantities consumed by the battery in each timing cycle to obtain the sum of the electric quantities, in some embodiments, in the timing process, after each timing cycle is ended, the electric quantities consumed in each timing cycle are counted, and then the sum of the electric quantities consumed in all timing cycles before the current timing cycle is added to obtain a new sum of the electric quantities. For example, after the timing is started and the first timing cycle is finished, the electric quantity consumed by the first timing cycle is counted, and the counted electric quantity consumed by the first timing cycle is recorded; after the second timing cycle is finished, counting the electric quantity consumed by the second timing cycle, adding the electric quantity consumed by the first timing cycle recorded before to obtain an electric quantity sum, recording the electric quantity sum, and then repeating the third timing cycle, the fourth timing cycle and the last timing cycle to obtain a final electric quantity sum. In other embodiments, after each timing cycle is finished, the amount of power consumed in the timing cycle is counted, the amount of power consumed in the timing cycles is recorded, and after the timing is stopped, the recorded amounts of power consumed in all timing cycles are summed to obtain a final total amount of power consumed.
In the step S43 of recording the sum of electric energy, after the sum of electric energy consumed in the whole timing process is counted, the sum of electric energy is recorded, and in some embodiments, the sum of electric energy recorded before the battery is saved so as to grasp the battery capacity change of the battery, thereby knowing the battery usage.
As shown in fig. 5, the step S5 of updating the battery capacity according to the sum of the electric quantity includes:
s51: reading the recorded electric quantity sum;
s52: the sum of the electric quantity is set as the battery capacity corresponding to the battery electric quantity percentage of 100%.
In the step S51 of reading the recorded electric quantity sum, the electric quantity sum recorded by the battery is read, and if there are a plurality of different electric quantity sum data, the latest electric quantity sum is read.
In the step S52 of setting the total quantity of electricity as the battery capacity corresponding to the battery electricity percentage of 100%, after reading the latest total quantity of electricity recorded by the battery, the total quantity of electricity is set as the current battery capacity of the battery, and the original standard battery capacity is replaced, so that the recorded capacity of the battery is consistent with the actual capacity of the battery, the compatibility between the battery and the device is improved, and the use experience of the device is optimized.
In summary, the present invention provides a method for updating battery capacity, which is applied to a device terminal, and when the percentage of battery capacity is detected to be 100% and no charging is performed, the method starts timing, monitors the battery state in real time during the timing process, stops timing when the percentage of battery capacity is detected to be 0% and no charging record is recorded from the timing, counts the total amount of power consumed during the timing process by using a calculus formula, and sets the counted total amount of power as the new battery capacity of the battery. By the method, the battery data can be updated in real time, and the change of the battery state can be correctly reflected, so that the compatibility of the battery and the equipment is improved, and the use experience of the equipment is optimized.
As shown in fig. 6, an embodiment of the present invention further provides a battery capacity updating system, including:
the judging module 10 is used for judging whether the current battery state is a preset starting state or not;
the timing module 20 is used for starting timing if the starting state is preset;
the monitoring module 30 is used for monitoring whether the battery state reaches a preset ending state in real time in the timing process;
the counting module 40 is used for stopping timing if the preset ending state is reached, and counting the total electric quantity consumed by the battery in the timing process;
and the updating module 50 is used for updating the battery capacity according to the sum of the electric quantity.
In the above-mentioned determining module 10, a starting state is preset in the device by the user as a starting point for counting the power consumption of the battery, and in some embodiments, the preset starting state refers to a state where both conditions that the percentage of the power of the battery is 100% and the battery is not in a charging state are satisfied. Only when the percentage of the battery capacity is 100%, the battery capacity is taken as a starting point of the statistics, and the battery capacity consumption counted by updating the battery capacity data is accurate, so that a complete battery capacity data can be obtained. Only when the battery is not in a charging state, namely no external electric quantity is charged for the battery, the statistics of the consumption of the electric quantity of the battery is meaningful, otherwise, the electric quantity of the battery is replenished all the time while being consumed, the total consumption of the counted electric quantity of the battery is larger than the actual capacity of the battery, and the accurate capacity of the battery cannot be obtained.
In the timing module 20, when the percentage of the battery power is detected to be 100% and the battery is not in a charging state, a timing is started to record the time of the subsequent battery power consumption statistics for subsequent calculation. The timing includes one or more timing cycles consisting of a predetermined time interval, and in some embodiments, the time interval of one timing cycle is set to 10s, i.e., each 10s goes from the previous timing cycle to the next timing cycle, and finally the whole timing process may include one or more timing cycles, i.e., one or more 10 s. The timing is performed by adopting the timing cycle, because in the process of battery power consumption, the battery power is not stably consumed at a certain rate, but is in continuous variation, that is, the current magnitude is continuously varied, the consumption rate at this moment may be completely different from the consumption rate at the next moment, the whole process from the battery power percentage consumption of 100% to the battery power percentage of 0% cannot calculate the power consumption through a uniform constant function, the power consumption can only be calculated by micro-integration according to the power calculation formula Q ═ I × t, and when the time t is sufficiently small, the current I can be regarded as a constant at this moment and is not varied. The time of one timing cycle corresponds to the t in the calculation formula, so that the sum of the electric quantity consumed by the battery from 100% to 0% can be accurately obtained through the sum of the electric quantity consumed by a plurality of timing cycles.
In the monitoring module 30, a user presets an ending state in the device as an end point of counting the power consumption of the battery, in some embodiments, the preset ending state refers to that the power percentage of the battery is 0%, and there is no charging record from the beginning of timing to the detection that the power percentage of the battery is 0%. At this time, even if the percentage of battery charge is detected to be 0%, since the presence of the uncharged mark is detected, that is, the charging record exists between the time when the timing is started and the time when the percentage of battery charge is detected to be 0%, the power consumption data corresponding to the actual battery capacity cannot be counted, and the subsequent step of counting the total power consumed by the battery is not performed.
In the above statistical module 40, if it is detected that the percentage of battery power is 0%, and there is no charging record from the beginning of timing to the detection that the percentage of battery power is 0%, it indicates that the battery has consumed from 100% of battery power to 0% of battery power, and there is no external power supplement midway, and the condition of calculating the complete battery capacity is satisfied, the total of battery power consumption can be counted. In some embodiments, during the timing process, after each timing cycle is ended, the consumed electric quantities of each timing cycle are counted, and then the sum of the consumed electric quantities of all timing cycles before the current timing cycle is added to obtain a new sum of the consumed electric quantities. For example, after the timing is started and the first timing cycle is finished, the electric quantity consumed by the first timing cycle is counted, and the counted electric quantity consumed by the first timing cycle is recorded; after the second timing cycle is finished, counting the electric quantity consumed by the second timing cycle, adding the electric quantity consumed by the first timing cycle recorded before to obtain an electric quantity sum, recording the electric quantity sum, and then repeating the third timing cycle, the fourth timing cycle and the last timing cycle to obtain a final electric quantity sum. In other embodiments, after each timing cycle is finished, the amount of power consumed in the timing cycle is counted, the amount of power consumed in the timing cycles is recorded, and after the timing is stopped, the recorded amounts of power consumed in all timing cycles are summed to obtain a final total amount of power consumed.
In the above-mentioned updating module 50, after counting the total amount of electricity consumed from the battery electricity percentage of 100% to the battery electricity percentage of 0%, the counted total amount of electricity is read and updated to the latest battery capacity. After the battery capacity is updated, the battery capacity recorded data is consistent with the actual data, and in the using process, the compatibility of the battery and the equipment is improved, and the using experience of the equipment is optimized.
As shown in fig. 7, in some embodiments, the determining module 10 includes:
a first judging unit 101, configured to judge whether a current power percentage of the battery is 100%;
a second determining unit 102, configured to determine whether the battery is in a charging state if the battery is in a charging state;
the first determination unit 103 is configured to determine that the current battery state is the preset starting state if the battery is not in the charging state.
In the first determining unit 101, only when the percentage of battery capacity is 100%, the battery capacity counted by the battery capacity data updating is accurate as the starting point of the statistics, and a complete battery capacity data can be obtained from the battery capacity percentage of 100% to the battery capacity percentage of 0%.
In the second determination unit 102, in some embodiments, it is determined whether the battery is in a charging state by determining whether the USB port is in a working state, and it is meaningful to count the consumption of the battery power only when the battery is not in the charging state, that is, no external power is supplied to the battery, otherwise the battery power is consumed and is always replenished, and the counted total consumption of the battery power is greater than the actual battery capacity, so that the accurate battery capacity cannot be obtained.
In the first determination unit 103, after the two determinations, that is, the preset starting state refers to a state in which both conditions that the percentage of battery charge is 100% and the battery is not in the charged state are satisfied, the state is taken as the starting point of the statistical battery charge consumption, so as to update the battery capacity data.
As shown in fig. 8, in some embodiments, the listening module 30 includes:
a third determining unit 301 that determines whether the battery power percentage is 0%;
a fourth determining unit 302, configured to determine whether a charging record exists between the time when the timing is started and the time when the percentage of battery power is 0% if the charging record exists;
the second determining unit 303 is configured to determine that the corresponding battery state is the preset end state when the battery power percentage is 0% if there is no charging record.
In the third determining unit 301, only when the battery capacity percentage is 0%, the battery capacity consumption counted as the updated battery capacity data is accurate, and a complete battery capacity data can be obtained from the battery capacity percentage of 100% to the battery capacity percentage of 0%.
In the above-mentioned fourth determination unit 302, in some embodiments, when the preset start state is detected, an uncharged flag is set up when the timing is started, the battery is monitored in real time during the timing, if the battery is detected to be in a charged state during the timing, a charged flag is set up to cover the uncharged flag set up before, and the timing is stopped. At this time, even if the percentage of battery charge is detected to be 0%, since the presence of the uncharged mark is detected, that is, the charging record exists between the time when the timing is started and the time when the percentage of battery charge is detected to be 0%, the power consumption data corresponding to the actual battery capacity cannot be counted, and the subsequent step of counting the total power consumed by the battery is not performed.
In the second determination unit 303, after the two determinations, that is, the preset end state refers to a state where the battery power percentage is 0% and no charging record is recorded from the beginning of timing to the detection of the battery power percentage being 0%, the state is taken as the statistical battery power consumption, so as to update the end point of the battery capacity data.
As shown in fig. 9, in some embodiments, statistics module 40 includes:
a counting unit 401, configured to count each electric quantity Q consumed by the battery in each timing cycle according to the following formula:
q ═ I × t, where I is the current in the clocked cycle and t is the preset time interval;
a summing unit 402, configured to sum the electric quantities consumed by the batteries in each timing cycle to obtain a sum of the electric quantities;
a recording unit 403 for recording the sum of the electric quantity.
In the above statistical unit 401, when the percentage of battery power is detected to be 100% and the battery is not in a charging state, a timer is started to record the time of the subsequent battery power consumption statistics for subsequent calculation. The timing includes one or more timing cycles consisting of a predetermined time interval, and in some embodiments, the time interval of one timing cycle is set to 10s, i.e., each 10s goes from the previous timing cycle to the next timing cycle, and finally the whole timing process may include one or more timing cycles, i.e., one or more 10 s. The timing is performed by adopting the timing cycle, because in the process of battery power consumption, the battery power is not stably consumed at a certain rate, but is in continuous variation, that is, the current magnitude is continuously varied, the consumption rate at this moment may be completely different from the consumption rate at the next moment, the whole process from the battery power percentage consumption of 100% to the battery power percentage of 0% cannot calculate the power consumption through a uniform constant function, the power consumption can only be calculated by micro-integration according to the power calculation formula Q ═ I × t, and when the time t is sufficiently small, the current I can be regarded as a constant at this moment and is not varied. The time of one timing cycle corresponds to the t in the calculation formula, so that the sum of the electric quantity consumed by the battery from 100% to 0% can be accurately obtained through the sum of the electric quantity consumed by a plurality of timing cycles.
In the above-mentioned summing unit 402, in some embodiments, during the timing process, after each timing cycle is ended, the consumed electric quantities of each timing cycle are counted, and then the sum of the consumed electric quantities of all timing cycles before the current timing cycle is added to obtain a new sum of the electric quantities. For example, after the timing is started and the first timing cycle is finished, the electric quantity consumed by the first timing cycle is counted, and the counted electric quantity consumed by the first timing cycle is recorded; after the second timing cycle is finished, counting the electric quantity consumed by the second timing cycle, adding the electric quantity consumed by the first timing cycle recorded before to obtain an electric quantity sum, recording the electric quantity sum, and then repeating the third timing cycle, the fourth timing cycle and the last timing cycle to obtain a final electric quantity sum. In other embodiments, after each timing cycle is finished, the amount of power consumed in the timing cycle is counted, the amount of power consumed in the timing cycles is recorded, and after the timing is stopped, the recorded amounts of power consumed in all timing cycles are summed to obtain a final total amount of power consumed.
In the recording unit 403, after the total amount of power consumed in the whole timing process is counted, the total amount of power is recorded, and in some embodiments, the total amount of power recorded before the battery is saved so as to grasp the battery capacity change of the battery, thereby knowing the battery usage.
As shown in fig. 10, in some embodiments, the update module 50 includes:
a reading unit 501, configured to read a recorded electric quantity sum;
a setting unit 502 for setting the sum of the capacities as a battery capacity corresponding to 100% of the battery capacity.
In the reading unit 501, the total amount of power recorded by the battery is read, and if there are a plurality of different total amount of power data, the latest total amount of power is read.
In the setting unit 502, after the latest electric quantity sum recorded by the battery is read, the electric quantity sum is set as the current battery capacity of the battery, and the original standard battery capacity is replaced, so that the battery recording capacity is consistent with the actual capacity of the battery, the compatibility between the battery and the equipment is improved, and the use experience of the equipment is optimized.
