[0026] Figure 3 The figure is a structural block diagram of an electronic device according to an exemplary embodiment. DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Before describing the embodiments of the present invention in detail, the current method for determining the battery status is first introduced.

[0029] Existing methods for determining battery status: Batteries in electronic devices are primarily managed by a power management chip, which controls the battery's charging and discharging processes, monitors the battery's status, and stores battery status information in a battery status register. Electronic devices can determine whether the battery is in a charging state, a discharging state, or a fully charged state based on the register value of the battery status register in the power management chip. When determining the battery status based solely on the register value of the battery status register, if the power management chip, battery, and related circuits are affected by external temperature, the register value of the battery status register can easily be incorrect, causing the electronic device to read an incorrect register value, which in turn prevents the electronic device from accurately determining the battery status.

[0030] One of the core concepts of the embodiment of the present invention is to comprehensively analyze the register value of the current current register, the register value of the remaining capacity register and the register value of the battery status register in the power management chip to determine the charge and discharge status of the battery.

[0031] Reference Figure 1 , shows a flowchart of a method for determining a battery status according to an embodiment of the present invention, which may specifically include the following steps:

[0032] Step 101: Determine a first battery state according to a register value of a current register corresponding to the battery.

[0033] Among them, the current value of the battery terminal is stored in the current register. When the register value of the current register is a positive value, it indicates that the battery is charging and the battery is in a charging state; when the register value of the current register is a negative value, it indicates that the battery is discharging and the battery state is a discharging state; when the register value of the current register is 0, it indicates that the battery is neither charging nor discharging, that is, the battery state is fully charged.

[0034] Optionally, step 101 may be implemented as follows:

[0035] Read the current register corresponding to the battery to obtain the value of the third register;

[0036] When the third register value is positive, determining that the first battery state is a charging state;

[0037] When the third register value is a negative value, determining that the first battery state is a discharge state;

[0038] When the third register value is 0, it is determined that the first battery state is a fully charged state.

[0039] In this embodiment, the electronic device can read the current current register to obtain the third register value stored in the current current register, so that the first battery state can be determined based on the third register value. For example, after reading the third register value, if the third register value is greater than 0 (a positive value), the first battery state is determined to be a charging state; if the third register value is less than 0 (a negative value), the first battery state is determined to be a discharging state; and when the third register value is equal to 0, the first battery state is determined to be a fully charged state. Among them, the process of reading the register value of the current current register can be set according to demand, and this embodiment does not limit this.

[0040] Step 102: Determine a second battery state according to the register value of the remaining capacity register.

[0041] The remaining capacity (RemainingCapacity) register stores the current remaining capacity of the battery. The battery state, ie, the second battery state, can be determined according to the change state of the current remaining capacity of the battery.

[0042] Optionally, step 102 may be implemented as follows:

[0043] Reading the remaining capacitance register at least twice to obtain at least two first register values;

[0044] When the values ​​of the first registers gradually increase in the reading order, determining that the second battery state is a charging state;

[0045] When the values ​​of the first registers gradually decrease in the order in which they are read, determining that the second battery state is a discharge state;

[0046] When the values ​​of the first registers do not change according to the reading sequence, it is determined that the second battery state is a fully charged state.

[0047] In this embodiment, the electronic device can read the register value of the remaining capacity register multiple times at different time points to obtain the first register value at different time points. For example, the electronic device can read the remaining capacity register for the first time at the first second to obtain a first register value, and read the remaining capacity register for the second time at the third second to obtain another first register value. The time interval between two adjacent readings of the remaining capacity register can be set as required, for example, to 1 second, 3 seconds, or 5 seconds. The number of times the remaining capacity register is read can be set as required, and this embodiment does not impose any restrictions on this.

[0048] When multiple first register values ​​are obtained, the electronic device can determine the second battery state based on the change state of the first register value, that is, the change state of the battery's current remaining capacity. 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 can be determined that the first register value gradually increases in the reading order, that is, the battery's current remaining capacity continues to increase, and the second battery state can be determined to be a charging state. On the contrary, 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 can be determined that the first register value gradually decreases in the reading order, that is, the battery's current remaining capacity continues to decrease, and the second battery state can be determined to be a discharging 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 also 80, it can be determined that the first register value does not change in the reading order, that is, the battery's current remaining capacity is constant, and the second battery state can be determined to be a fully charged state.

[0049] Step 103: Determine a third battery status according to the register value of the battery status register.

[0050] Among them, the battery status register is a 16-bit register. In the battery status register, when the fifth bit (bit5) is 1, it indicates that the battery status is fully charged; when the sixth bit (bit6) is 1, it indicates that the battery status is discharged; when both bit5 and bit6 are not 1, it indicates that the battery status is charged.

[0051] Optionally, step 103 may be implemented as follows:

[0052] Read the battery status register to obtain the fourth register value;

[0053] When the fifth bit and the sixth bit of the fourth register value are both not 1, determining that the third battery state is a charging state;

[0054] When the sixth bit of the fourth register value is 1, determining that the third battery state is a discharge state;

[0055] When the fifth bit of the fourth register value is 1, it is determined that the third battery state is a fully charged state.

[0056] In this embodiment, the electronic device can read the battery status register to obtain the fourth register value. When the fifth bit and the sixth bit of the fourth register value are both not 1, the third battery status is determined to be a charging state. When the sixth bit of the fourth register value is 1, the third battery status is determined to be a discharging state. When the fifth bit of the fourth register value is 1, the third battery status is determined to be a fully charged state. The process of the electronic device reading the battery status register can be set as needed and is not limited in this embodiment.

[0057] Step 104: Determine the charge and discharge status of the battery according to the first battery status, the second battery status, and the third battery status.

[0058] In this embodiment, after determining the first battery state, the second battery state, and the third battery state, the battery charge and discharge state can be determined by combining the first battery state, the second battery state, and the third battery state. The current value of the battery terminal is stored in the current current register, the battery's current remaining capacity is stored in the remaining capacity register, and the battery status register stores the battery status information determined by the battery management chip. The battery charge and discharge state is determined based on the first battery state, the second battery state, and the third battery state. The battery charge and discharge state can be determined by comprehensively analyzing the current value of the battery terminal, the battery's current remaining capacity, and the battery's current status information. Compared to the prior art method of determining the battery charge and discharge state based solely on the register value of the battery status register, this method can avoid the problem of being unable to accurately determine the battery charge and discharge state when the status information in the battery status register is erroneous.

[0059] For example, step 104 may be implemented as follows:

[0060] determining that the battery is in a charging state when at least two of the first battery state, the second battery state, and the third battery state are charging states;

[0061] determining that the battery is in a discharging state when at least two of the first battery state, the second battery state, and the third battery state are in a discharging state;

[0062] When at least two of the first battery state, the second battery state, and the third battery state are fully charged states, it is determined that the battery is in the fully charged state.

[0063] For example, the electronic device can determine that the battery is in a charging state when the first battery state and the second battery state are charging states, or determine that the battery is in a 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 a charging state when the second battery state and the third battery state are charging states.

[0064] Similarly, the electronic device can determine that the battery is in a discharging state when the first battery state and the second battery state are in a discharging state, or determine that the battery is in a discharging state when the first battery state, the second battery state and the third battery state are all in a discharging state, or determine that the battery is in a discharging state when the second battery state and the third battery state are in a discharging state.

[0065] Similarly, the electronic device can determine that the battery is fully charged when the first battery status and the second battery status are fully charged, or determine that the battery is fully charged when the first battery status, the second battery status and the third battery status are all fully charged, or determine that the battery is fully charged when the second battery status and the third battery status are fully charged.

[0066] Optionally, step 104 may further include:

[0067] When the first battery state, the second battery state, and the third battery state simultaneously include a charging state, a discharging state, and a fully charged state, it is determined that the battery is in the second battery state.

[0068] In this embodiment, when the first battery state, the second battery state, and the third battery state all include a charging state, a discharging state, and a fully charged state, the battery is determined to be 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 shall prevail. For example, if the first battery state is a charging state, the second battery state is a discharging state, and the third battery state is a fully charged state, the battery is determined to be in the discharging state.

[0069] In actual applications, the second battery status is determined based on the change in the remaining capacity. Compared with the first battery status and the third battery status, the second battery status is more accurate. When the battery status cannot be determined based on the first battery status, the second battery status and the third battery status, the accuracy of the battery status can be improved based on the second battery status.

[0070] For example, step 104 may also be implemented in the following manner:

[0071] When the first battery state, the second battery state, and the third battery state are the same battery state, determining that the batteries are in the same battery state;

[0072] When different battery states are included among the first battery state, the second battery state, and the third battery state, it is determined that the battery is in the second battery state.

[0073] In this embodiment, when the first battery status, the second battery status, and the third battery status are the same battery status, it can be determined that there are no external factors affecting the battery status, and the first battery status, the second battery status, and the third battery status are all accurate battery statuses. In this case, it can be determined that the batteries are in the same battery status. For example, if the first battery status, the second battery status, and the third battery status are all charging states, it can be determined that the batteries are in a charging state.

[0074] On the contrary, when the first battery status, the second battery status, and the third battery status include different battery states, it can be determined that there is an external factor affecting the battery, and one of the first battery status, the second battery status, and the third battery status may be inaccurate. In this case, the second battery status can be used as the standard. For example, when the first battery status and the third battery status are charging states, and the second battery status is discharging state, it can be determined that the battery is in the discharging state.

[0075] In actual applications, when there may be an inaccurate battery status among the first battery status, the second battery status, and the third battery status, the accuracy of the battery status may be improved by taking the second battery status as the standard.

[0076] In an embodiment of the present invention, a first battery state is determined based on the register value of a current current register corresponding to the battery, a second battery state is determined based on the register value of a remaining capacity register, a third battery state is determined based on the register value of a battery status register, and the charge and discharge state of the battery is determined based on the first battery state, the second battery state, and the third battery state. By comprehensively analyzing the register value of the current current register, the register value of the remaining capacity register, and the register value of the battery status register to determine the charge and discharge state of the battery, the charge and discharge state of the battery can be determined more accurately than the prior art method of determining the charge and discharge state of the battery based solely on the register value of the battery status register.

[0077] Optionally, when determining the second battery state according to the register value of the remaining capacity register, the method may further include:

[0078] Read the full-charge capacity register to obtain the second register value;

[0079] When any first register value is equal to the second register value, it is determined that the second battery state is a fully charged state.

[0080] Among them, the full charge capacity (FullchargeCapacity) register is used to store the package capacity of the battery. The package capacity is the capacity of the battery after it is fully charged. When the package capacity is equal to the current remaining capacity of the battery, it means that the battery capacity is full, that is, the battery is in a fully charged state.

[0081] In this embodiment, the electronic device can read the full-charge capacity register to obtain a second register value. After obtaining the first register value and the second register value, the first register value and the second register value can be compared. 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 package capacity of the battery after being fully charged, it means that the battery is fully charged, and the second battery state can be determined to be a fully charged state.

[0082] In practical applications, the second battery state can be quickly determined by comparing the first register value and the second register value. For example, after obtaining the first register value for the first time, if the first register value is determined to be equal to the second register value that has already been obtained, the second battery state can be determined to be fully charged, thereby avoiding the need to obtain the first register value again and reducing the power consumption of the electronic device.

[0083] Optionally, when the values ​​of the first registers gradually increase in the order in which they are read, the step of determining that the second battery state is the charging state may be implemented in the following manner:

[0084] When the values ​​of the first registers gradually increase according to the reading sequence and the increase amplitude is not less than the preset charging threshold, it is determined that the second battery state is the charging state.

[0085] In this embodiment, in the process of comparing multiple first register values ​​read sequentially, when each first register value gradually increases in the reading order, the difference between two adjacent first registers can be compared to determine the increase rate. When the difference between the two adjacent first register values ​​is greater than or equal to the preset charging threshold, it can be determined that the increase rate is not less than the preset charging threshold, and the second battery state is the charging state. In combination with the above 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 can be determined that the first register value gradually increases in 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 less than the preset charging threshold of 20, then the second battery state can be determined to be the charging state. The specific value of the preset charging threshold can be set according to needs, and this embodiment does not limit this.

[0086] In actual applications, when the first register value gradually increases in the reading order, the increase amplitude can be determined. When the increase amplitude is not lower than the preset charging threshold, the second battery state is determined to be the charging state, which can more accurately determine the second battery state.

[0087] Optionally, when the values ​​of the first registers gradually decrease in the reading order, the step of determining that the second battery state is the discharge state can be implemented as follows:

[0088] When the values ​​of the first registers gradually decrease according to the reading order and the decrease amplitude is not lower than the preset discharge threshold, it is determined that the second battery state is the discharge state.

[0089] In this embodiment, in the process of comparing multiple first register values ​​read sequentially, when each first register value gradually decreases in the reading order, the difference between two adjacent first registers can be compared to determine the reduction amplitude. When the difference between any two adjacent first register values ​​is less than or equal to the preset charging threshold, it can be determined that the reduction amplitude is not less than the preset discharge threshold, and the second battery state is a discharge state. In combination with 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 can be determined that the first register value gradually decreases in 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 less than the preset discharge threshold of 10, then the second battery state can be determined to be a discharge state. The specific value of the preset discharge threshold can be set according to demand, and this embodiment does not impose any restrictions on this.

[0090] In practical applications, when the first register value gradually decreases in the reading order, the decrease amplitude can be determined. When the decrease amplitude is not lower than the preset discharge threshold, the second battery state is determined to be the discharge state, which can more accurately determine the second battery state.

However, those skilled in the art should be aware that the embodiments of the present invention are not limited by the order of the actions described, because according to the embodiments of the present invention, certain steps can be performed in other orders or simultaneously.
