Currently, a battery in an electronic device is provided with a protection circuit, and the battery shown in fig. 1 is provided with two groups of protection circuits, namely, the protection circuit 1 comprises a precision resistor 3 and a protection switching device 5, and the protection circuit 2 comprises a precision resistor 4 and a protection switching device 6. In practical application, the protection circuit 1 and the protection circuit 2 can be used for performing single fault test on the battery, thereby meeting the requirement of safety regulations LPS (limit power source). However, the existing protection circuit cannot detect the internal short circuit of the battery cell 8, which results in limited protection function.
To solve the above technical problems, an embodiment of the present disclosure provides a method for obtaining a battery state, and to implement the method, in an embodiment of the present disclosure, the structure of the battery shown in fig. 1 is first appropriately adjusted, and fig. 2 is a schematic structural diagram of the battery according to an exemplary embodiment. It should be noted that, in the battery structure shown in fig. 2 in this embodiment, the connection line between two devices indicates that there is an electrical connection relationship between the two devices, and does not indicate that there is only one connection line.
Referring to fig. 2, the battery provided in this embodiment includes a set of protection circuits composed of a precision resistor 3 and a protection chip 1. Based on the connection of the precision resistor 3 with one end of the battery cell 8, the precision resistor 3 can be used to detect the current of the battery cell 8 during the charging or discharging of the battery cell 8.
For example, the protection chip 1 may obtain the voltage at the CS end of the precision resistor 3, calculate the current on the precision resistor 3 according to the voltage on the precision resistor 3 and the resistance value of the precision resistor 3, and determine whether the charging or discharging circuit is over-current according to the current. The protection switching device 5 can be turned off in the event of an overcurrent, so that the battery cells 8 are protected. Similarly, the battery gauge 7 may calculate the current on the precision resistor 3 to determine whether the charge or discharge circuit is over-current. The protection switching device 6 can be turned off in the event of an overcurrent, so that the battery cells 8 are protected.
In addition, the protection chip 1 can also acquire the voltage of the battery cell 8, compare the voltage with a voltage threshold value, and compare to determine whether the charging or discharging loop is over-voltage. The protection switching device 5 can be switched off in the event of an overvoltage, so that the battery cells 8 are protected. Likewise, the battery gauge 7 may also acquire the voltage of the battery cell 8, compare this voltage to a voltage threshold, and compare to determine if the charge or discharge circuit is over-voltage. The protection switching device 6 can be turned off in the event of an overvoltage, so that the battery cells 8 are protected.
It should be noted that, in this embodiment, the operation process of the protection circuit in the battery is only schematically described, and may be appropriately adjusted according to a specific scenario in practical application.
Based on the battery shown in fig. 2, the embodiment of the present disclosure further provides a method for acquiring a battery state, and fig. 3 is a flowchart illustrating a method for acquiring a battery state according to an exemplary embodiment. Referring to fig. 3, a method for obtaining a battery state may be applied to a battery fuel gauge, including steps 301 to 304, where:
in step 301, after the battery is switched to the rest mode, the voltage of the battery cell in the battery is obtained, and a first voltage is obtained.
In this embodiment, the battery may include a plurality of operation modes, such as a rest mode, a charging mode, or a discharging mode, which may be set according to a specific scenario, and is not limited herein.
In this embodiment, the battery is switched to the rest mode when the battery is in an initial mode including one of a charge mode and a discharge mode, see fig. 4, including that in step 401, the current of the precision resistor 3 can be detected in the initial mode, which is referred to as an initial current to show the difference. In step 402, whether the initial current satisfies a preset condition may be turned off, and when the preset condition is satisfied, the battery may be switched from the initial mode to the rest mode. When the preset condition is not satisfied, the current of the precision resistor 3 may be re-detected.
In one embodiment, determining whether the initial current meets the preset condition, see fig. 5, may include, in step 501, acquiring a current threshold and a duration threshold in the initial mode. For example, when the initial mode is the charge mode, the current threshold is Rest ChgI, and when the initial mode is the discharge mode, the current threshold is Rest DsgI. As another example, the duration threshold may be Rest Time. It should be noted that the current threshold and the duration threshold may be set according to a specific scenario, which is not limited herein. In step 502, it may be determined whether the initial current is less than a current threshold. In step 503, the duration is recorded when the initial current is less than the current threshold, and the initial current is re-detected when the initial current is greater than the current threshold. In step 504, when the duration exceeds the duration threshold, it is determined that the initial current meets the preset condition, and when the duration is less than the duration threshold, it is determined that the initial current does not meet the preset condition, and the initial current is re-detected.
In the case where the initial mode is the charging mode, the initial Current Charge Current of the precision resistor 3 is detected, and the magnitudes of the initial Current Charge Current and the charging Current threshold Rest ChgI are determined. When the Charge Current is less than Rest ChgI, recording duration DELAY TIME is started, and when the Charge Current is greater than Rest ChgI, the Charge Current is re-detected. When DELAY TIME exceeds the Rest Time, the Charge Current is indicated to meet the preset condition, the battery can be switched to the Rest mode, and when DELAY TIME is smaller than the Rest Time, the Charge Current is indicated to not meet the preset condition, and the Charge Current can be detected again.
In this embodiment, after the Battery is switched to the rest mode, the Voltage of the Battery cell 8 may be detected, which is hereinafter referred to as the first Voltage Battery Voltage 1 to show the difference. With continued reference to fig. 2, taking the battery electricity meter 7 as an example, the battery electricity meter 7 is electrically connected to the ground and the positive electrode of the battery cell 8, respectively, and the voltage of the battery cell 8 can be obtained. Taking the protection chip 1 as an example, the protection chip 1 is electrically connected with the ground and the positive electrode of the battery cell 8 respectively, so that the voltage of the battery cell 8 can be obtained.
It should be noted that, when the battery is in the stationary mode, the first voltage of the battery cell 8 may be directly detected.
In step 302, the current in the precision resistor is detected in the rest mode to obtain a rest current.
In this embodiment, the current of the precision resistor 3 can be detected in the rest mode to obtain the rest current. The obtaining manner is the same as that of the above-mentioned embodiment, and will not be described in detail here.
In step 303, when the rest current meets a preset condition, the voltage of the battery cell is continuously obtained, and a second voltage is obtained.
In this embodiment, whether the standing current meets the preset condition can be determined in the same manner as the principle of the embodiment shown in fig. 5, and the specific content is referred to the embodiments shown in fig. 5 and fig. 5, which are not repeated here.
In this embodiment, when the standing current meets the preset condition, the Voltage of the Battery cell 8 may be continuously obtained, which is referred to as the second Voltage Battery Voltage 2 to show the difference.
In step 304, the battery state is determined to be a normal state when the difference voltage between the second voltage and the first voltage is less than a difference threshold, and the battery state is determined to be an abnormal state when the difference voltage exceeds the difference threshold.
In this embodiment, a Voltage difference Voltage of the first Voltage and the second Voltage, i.e., voltage 2-Voltage 1, may be obtained. Wherein the Battery Voltage2-Battery Voltage 1 may represent the offset of Battery Voltage2 and Battery Voltage 1. The difference Voltage (Battery Voltage2-Battery Voltage 1) may then be compared to a difference threshold Abnormal Delta Voltage. When the Voltage of the Battery Voltage2-Battery Voltage 1 is smaller than Abnormal Delta Voltage, it indicates that the voltages detected in the two times are the same or similar in the standing mode, and the Battery cell 8 has no discharging or charging problem, i.e. the Battery is in a normal state. When the Voltage 2-Voltage 1 exceeds Abnormal Delta Voltage, it indicates that in the standing mode, the Voltage detected twice has a large difference, and the Battery cell 8 has a discharging or charging problem, i.e., the Battery is in an abnormal state.
In this embodiment, with continued reference to fig. 2, after the battery electricity meter 7 determines that the battery is in an abnormal state, the specified pin (INT) of the battery electricity meter 7 may also be turned off to electrically connect the protection switching device 6 with the specified pin, so as to disconnect the charging or discharging circuit of the current and protect the battery cell 8.
In an embodiment, with continued reference to fig. 2, when the precision resistor 3 is shorted and the Battery cell 8 has an internal short circuit, the initial current and the rest current detected by the Battery fuel gauge 7 are both 0, and the first Voltage and the second Voltage are both 0, and considering that the Battery cell 8 consumes power due to the internal short circuit, the second Voltage is the first Voltage, that is, voltage 2-Battery Voltage 1 is less than Abnormal Delta Voltage, and it can still be determined that the Battery is in an abnormal state. In other words, the present embodiment can detect a problem of an internal short circuit of the battery cell 8 in the case where the precision resistor 3 is short-circuited.
In one embodiment, with continued reference to fig. 2, when the protection chip 1 fails and there is an internal short circuit in the battery cell 8, the battery fuel gauge 7 is still able to detect that the battery is in an abnormal state. In other words, the present embodiment can detect the problem of the internal short circuit of the battery cell 8 in the case that the protection chip 1 fails, and compared with the related art, the present embodiment can use a small number of protection circuits, which is beneficial to reducing the number of protection devices in the battery and reducing the production cost.
In this embodiment, the battery is switched to the rest mode to obtain two voltages, and the two voltages are used to determine whether the battery is in a normal state or an abnormal state, for example, the battery is not discharged in the rest mode, the two voltages are equal or similar, that is, the difference voltage is smaller than the difference threshold value, and the battery is determined to be in a normal state, for example, the voltage is continuously reduced when the battery is likely to generate an internal short circuit in the rest mode, that is, the difference voltage is larger than the difference threshold value, and the battery is determined to be in an abnormal state, so that a single fault test and an internal short circuit test can be performed on the battery, and the protection performance of the battery is improved when the LPS requirement is met.
Next, referring to fig. 6, in conjunction with the process of detecting the state of the battery in the charging mode, the charging Current Charge Current of the battery can be detected through the precision resistor, the charging Current Charge Current is compared with the charging Current threshold Rest ChgI, if the charging Current exceeds Rest ChgI, the charging Current is detected again, and if the charging Current is less than Rest ChgI, the duration DELAY TIME is recorded. Then, comparing the duration DELAY TIME with a duration threshold RestTime, if DELAY TIME is smaller than the RestTime, detecting the charging current again, if DELAY TIME exceeds the RestTime, switching the battery to a Rest mode, and detecting the first voltage of the battery cell.
And continuously detecting the standing current of the battery, and comparing the standing current with a current threshold value. If the rest current exceeds the current threshold Rest ChgI, the rest current is re-detected. If the rest current is less than Rest ChgI, the duration DELAY TIME is recorded. Thereafter, the duration DELAY TIME is compared to a duration threshold RestTime, and if DELAY TIME is less than RestTime, the charge current is re-detected, and if DELAY TIME exceeds RestTime, the second voltage of the battery cell is detected.
And acquiring a difference voltage of the second voltage and the first voltage, comparing the difference voltage with a difference voltage threshold, detecting the standing current again if the difference voltage is smaller than the difference voltage threshold, determining that the battery is in an abnormal state if the difference voltage exceeds the difference voltage threshold, enabling a specified pin INT by a battery fuel gauge, switching off a protection switch 6, and disconnecting a charging loop of the battery to protect a battery cell 8.
