Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Before describing embodiments of the present invention in detail, a description will be given of a current battery state determination method.
The existing battery state determination method comprises the following steps: the battery in the electronic equipment is mainly managed by a power management chip, the power management chip controls the charging and discharging processes of the battery, monitors the state of the battery and stores the state information of the battery in a battery state register. The electronic device can determine that the battery is in a charging state, a discharging state or a fully charged state according to the register value of the battery state register by reading the register value of the battery state register in the power management chip. When the battery state is determined only according to the register value of the battery state register, when the power management chip, the battery and the related circuits are affected by the external temperature, the register value of the battery state register is easy to be wrong, so that the electronic equipment reads the wrong register value, and the electronic equipment cannot accurately determine the battery state.
One of the core ideas of the embodiment of the invention is to comprehensively analyze the register value of the current register, the register value of the residual electric capacity register and the register value of the battery state register in the power management chip to determine the charging and discharging state of the battery.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a battery status determining method according to the present invention is shown, which may specifically include the following steps:
step 101, determining a first battery state according to a register value of a current register corresponding to a battery.
The Current register (Current) stores the Current value of the battery terminal, and when the register value of the Current register is a positive value, the Current register indicates that the battery is being charged and the battery is in a charging state; when the register value of the current register is a negative value, the battery is discharged, and the battery state is a discharge state; when the register value of the current register is 0, it indicates that the battery is not charged or discharged, i.e. the battery status is a fully charged status.
Alternatively, step 101 may be implemented as follows:
reading a current register corresponding to the battery to obtain a third register value;
when the third register value is a positive value, determining that the first battery state is a charging state;
when the third register value is a negative value, determining that the first battery state is a discharging state;
when the third register value is 0, the first battery state is determined to be a fully charged state.
In this embodiment, the electronic device may read the current register to obtain a third register value stored in the current register, so that the first battery state may be determined according to the third register value. Exemplarily, after the third register value is read, if the third register value is greater than 0 (positive value), the first battery state is determined to be the charging state; if the third register value is less than 0 (negative value), determining that the first battery state is a discharging state; and determining that the first battery state is a fully charged state when the third register value is equal to 0. The process of reading the register value of the current register may be set according to a requirement, which is not limited in this embodiment.
And step 102, determining a second battery state according to the register value of the residual electric capacity register.
Wherein, the remaining capacity (remaining capacity) register stores the current remaining capacity of the battery, and the state of the battery, i.e., the second battery state, can be determined according to the change state of the current remaining capacity of the battery.
Alternatively, step 102 may be implemented as follows:
reading the residual electric capacity register at least twice to obtain at least two first register values;
when the values of the first registers gradually increase according to the reading sequence, determining that the second battery state is a charging state;
when the values of the first registers are gradually reduced according to the reading sequence, determining that the second battery state is a discharging state;
and when the values of the first registers are not changed according to the reading sequence, determining that the second battery state is a fully charged state.
In this embodiment, the electronic device may read the register value of the residual capacitance register for multiple times at different time points, respectively, to obtain the first register value at different time points. For example, the electronic device may read the remaining capacity register for a first time in a first second to obtain a first register value, and read the remaining capacity register for a second time in a third second to obtain another first register value. The time interval between two adjacent readings of the remaining capacity register may be set according to the requirement, and may be, for example, 1 second, 3 seconds or 5 seconds. The number of times of reading the remaining capacity register may be set according to a requirement, which is not limited in this embodiment.
When the plurality of first register values are acquired, the electronic device may determine the second battery state according to a change state of the first register values, that is, a change state of a currently remaining capacity of the battery. For example, if the first register value read for the first time is 50 and the first register value read for the second time is 70, it may be determined that the first register values are gradually increased in the reading order, that is, the current remaining capacity of the battery is continuously increased, and at this time, it may be determined that the second battery state is the charging state. In contrast, if the first register value read for the first time is 80 and the first register value read for the second time is 60, it may be determined that the first register values are gradually decreased in the reading order, that is, the current remaining capacity of the battery is continuously decreased, and at this time, it may be determined that the second battery state is the discharge state. Similarly, if the first register value read for the first time is 80 and the first register value read for the second time is 80, it may be determined that the first register value is unchanged according to the reading sequence, that is, the current remaining capacity of the battery is constant, and at this time, it may be determined that the second battery state is a fully charged state.
And step 103, determining a third battery state according to the register value of the battery state register.
The battery state register is a 16-bit register, and in the battery state register, when the fifth bit (bit5) is 1, the battery state is a fully charged state, when the sixth bit (bit6) is 1, the battery state is a discharged state, and when neither bit5 nor bit6 is 1, the battery state is a charged state.
Alternatively, step 103 may be implemented as follows:
reading the battery state register to obtain a fourth register value;
when the fifth bit and the sixth bit of the fourth register value are not 1, determining that the third battery state is a charging state;
when the sixth bit of the fourth register value is 1, determining that the third battery state is a discharge state;
when the fifth bit of the fourth register value is 1, the third battery state is determined to be a fully charged state.
In this embodiment, the electronic device may read the battery status register, obtain the fourth register value, determine that the third battery status is the charging status when neither the fifth bit nor the sixth bit of the fourth register value is 1, determine that the third battery status is the discharging status when the sixth bit of the fourth register value is 1, and determine that the third battery status is the fully charged status when the fifth bit of the fourth register value is 1. The process of reading the battery status register by the electronic device may be set according to requirements, and the embodiment is not limited herein.
And 104, determining the charge and discharge state of the battery according to the first battery state, the second battery state and the third battery state.
In this embodiment, after the first battery state, the second battery state, and the third battery state are determined, the first battery state, the second battery state, and the third battery state may be integrated to determine the charge/discharge state of the battery. The current register stores the current value of the battery terminal, the residual capacity register stores the current residual capacity of the battery, and the battery state register stores the state information of the battery determined by the battery management chip. And determining the charge and discharge state of the battery according to the first battery state, the second battery state and the third battery state, and comprehensively analyzing the current value of the battery terminal, the current residual capacity of the battery and the current state information of the battery to determine the charge and discharge state of the battery. Compared with the method for determining the battery charging and discharging state only according to the register value of the battery state register in the prior art, the method can solve the problem that the battery charging and discharging state cannot be determined accurately when the state information in the battery state register is wrong.
Illustratively, step 104 may be implemented by:
determining that the battery is in a charged state when at least two of the first battery state, the second battery state, and the third battery state are in charged states;
determining that the battery is in a discharged state when at least two of the first battery state, the second battery state, and the third battery state are in a discharged state;
determining that the battery is in a fully charged state when at least two of the first battery state, the second battery state, and the third battery state are in the fully charged state.
For example, the electronic device may determine that the battery is in the charging state when the first battery state and the second battery state are in the charging state, or determine that the battery is in the charging state when the first battery state, the second battery state, and the third battery state are all charging states, or determine that the battery is in the charging state when the second battery state and the third battery state are in the charging states.
Similarly, the electronic device may determine that the battery is in the discharge state when the first battery state and the second battery state are in the discharge state, or determine that the battery is in the discharge state when the first battery state, the second battery state, and the third battery state are all in the discharge state, or determine that the battery is in the discharge state when the second battery state and the third battery state are in the discharge state.
Similarly, the electronic device may determine that the battery is in the fully charged state when the first battery state and the second battery state are in the fully charged state, or determine that the battery is in the fully charged state when the first battery state, the second battery state, and the third battery state are all in the fully charged state, or determine that the battery is in the fully charged state when the second battery state and the third battery state are in the fully charged state.
Optionally, step 104 may further include:
and when the first battery state, the second battery state and the third battery state simultaneously comprise a charging state, a discharging state and a full-charging state, determining that the battery is in the second battery state.
In this embodiment, when the first battery state, the second battery state, and the third battery state simultaneously include the charge state, the discharge state, and the full charge state, it is determined that the battery is in the second battery state. That is, when the first battery state, the second battery state and the third battery state are different battery states, the second battery state is taken as the standard. For example, if the first battery state is a charged state, the second battery state is a discharged state, and the third battery state is a fully charged state, it is determined that the battery is in the discharged state.
In practical application, the second battery state is determined according to the change state of the residual electric capacity, the accuracy is higher compared with the first battery state and the third battery state, and when the battery state cannot be determined according to the first battery state, the second battery state and the third battery state, the accuracy of the battery state can be improved based on the second battery state.
Illustratively, step 104 may also be implemented by:
when the first battery state, the second battery state and the third battery state are the same battery state, determining that the batteries are the same battery state;
when the first battery state, the second battery state and the third battery state comprise different battery states, determining that the battery is in the second battery state.
In this embodiment, when the first battery state, the second battery state, and the third battery state are the same battery state, it may be determined that there is no influence of external factors, and the first battery state, the second battery state, and the third battery state are all accurate battery states, and at this time, it may be determined that the batteries are in the same battery state. For example, if the first battery state, the second battery state, and the third battery state are all charge states, it may be determined that the battery is in a charge state.
Conversely, when the first battery state, the second battery state, and the third battery state include different battery states, it may be determined that there is an influence of the external factor, and an inaccurate battery state may exist among the first battery state, the second battery state, and the third battery state, and at this time, the second battery state may be used as a reference. For example, when the first battery state and the third battery state are a charged state and the second battery state is a discharged state, it may be determined that the battery is in a discharged state.
In practical application, when the first battery state, the second battery state and the third battery state may have inaccurate battery states, the accuracy of the battery states can be improved with the second battery state as a standard.
In the embodiment of the invention, the first battery state is determined according to the register value of the current register corresponding to the battery, the second battery state is determined according to the register value of the residual electric capacity register, the third battery state is determined according to the register value of the battery state register, and the charging and discharging state of the battery is determined according to the first battery state, the second battery state and the third battery state. The charging and discharging state of the battery is determined by comprehensively analyzing the register value of the current register, the register value of the residual capacity register and the register value of the battery state register.
Optionally, when determining the second battery state according to the register value of the remaining electric capacity register, the method may further include:
reading the full-capacity register to obtain a second register value;
when any of the first register values is equal to the second register value, the second battery state is determined to be a fully charged state.
The full capacity (full charge capacity) register is used for storing the packing capacity of the battery, the packing capacity is the capacity of the fully charged battery, and when the packing capacity is equal to the current residual capacity of the battery, the full capacity of the battery is indicated, that is, the battery is in a fully charged state.
In this embodiment, the electronic device may read the full capacity register to obtain the second register value. After the first register value and the second register value are obtained, the first register value and the second register value can be compared, and when any one of the first register values is equal to the second register value, that is, the current remaining capacity of the battery is equal to the packaging capacity of the fully charged battery, which indicates that the battery is fully charged, the second battery state can be determined to be a fully charged state.
In practical application, the second battery state can be rapidly determined by comparing the first register value with the second register value. For example, after the first register value is obtained for the first time, if it is determined that the first register value is equal to the obtained second register value, it may be determined that the second battery state is a fully charged state, so that it may be avoided to obtain the first register value again, and power consumption of the electronic device may be reduced.
Alternatively, when the respective first register values gradually increase in the reading order, the step of determining that the second battery state is the charging state may be implemented as follows:
and when the values of the first registers gradually increase according to the reading sequence and the increasing amplitude is not lower than a preset charging threshold value, determining that the second battery state is a charging state.
In this embodiment, in the process of comparing the plurality of first register values read in the sequence, when each first register value gradually increases according to the reading sequence, the difference between two adjacent first registers may be compared to determine the increase range, and when the difference between two adjacent first register values is greater than or equal to the preset charging threshold, it may be determined that the increase range is not lower than the preset charging threshold, and the second battery state is the charging state. With reference to the foregoing example, if the first register value read for the first time is 50, and the first register value read for the second time is 70, it may be determined that the first register values gradually increase according to the reading sequence, and the difference between the first register value read for the first time and the first register value read for the second time is not lower than the preset charging threshold 20, and then it may be determined that the second battery state is the charging state. The specific value of the preset charging threshold may be set according to the requirement, which is not limited in this embodiment.
In practical application, when the first register value gradually increases according to the reading sequence, the increasing amplitude can be determined, and when the increasing amplitude is not lower than the preset charging threshold, the second battery state is determined to be the charging state, so that the second battery state can be determined more accurately.
Alternatively, when the respective first register values are gradually decreased in the reading order, the step of determining that the second battery state is the discharge state may be implemented as follows:
and when the values of the first registers are gradually reduced according to the reading sequence and the reduction amplitude is not lower than a preset discharge threshold value, determining that the second battery state is a discharge state.
In this embodiment, in the process of comparing the plurality of first register values read in sequence, when each first register value gradually decreases according to the reading sequence, the difference between two adjacent first registers may be compared to determine the decrease range, and when the difference between any two adjacent first register values is less than or equal to the preset charging threshold, it may be determined that the decrease range is not less than the preset discharging threshold, and the second battery state is the discharging state. With reference to the above example, if the first register value read for the first time is 70 and the first register value read for the second time is 60, it may be determined that the first register values gradually decrease according to the reading order, and the difference between the first register value read for the first time and the first register value read for the second time is not lower than the preset discharge threshold 10, and at this time, it may be determined that the second battery state is the discharge state. The specific value of the preset discharge threshold may be set according to the requirement, and this embodiment does not limit this.
In practical application, when the first register value is gradually reduced according to the reading sequence, the reduction amplitude can be determined, and when the reduction amplitude is not lower than a preset discharge threshold, the second battery state is determined to be a discharge state, so that the second battery state can be more accurately determined.
