[0051] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0052] At present, the batteries in electronic devices are equipped with protection circuits. Figure 1 The battery shown in the figure has two sets of protection circuits: protection circuit 1 includes precision resistor 3 and protection switch device 5; protection circuit 2 includes precision resistor 4 and protection switch device 6. In practical applications, the battery can be tested for single faults using protection circuit 1 and protection circuit 2, thereby meeting the requirements of the safety regulation LPS (limited power source). However, the existing protection circuit cannot detect when an internal short circuit occurs in the battery cell 8, resulting in limited protection function.

[0053] In order to solve the above technical problems, the embodiment of the present disclosure provides a method for obtaining the battery status. To implement the above method, the embodiment of the present disclosure first Figure 1 The structure of the battery shown is appropriately adjusted. Figure 2 is a schematic diagram of the structure of a battery according to an exemplary embodiment. Figure 2 In the battery structure shown, a line connecting two devices indicates that there is an electrical connection between the two devices, and does not mean that there is only one line connecting the two devices.

[0054] See also Figure 2 A battery provided in this embodiment includes a set of protection circuits, which are composed of a precision resistor 3 and a protection chip 1. Since the precision resistor 3 is connected to 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 process of the battery cell 8.

[0055] For example, the protection chip 1 can obtain the voltage on the CS end of the precision resistor 3, and 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. According to the current, it can be judged whether the charging or discharging circuit is overcurrent. When overcurrent occurs, the protection switch device 5 can be turned off to protect the battery cell 8. Similarly, the battery fuel gauge 7 can also calculate the current on the precision resistor 3 to judge whether the charging or discharging circuit is overcurrent. When overcurrent occurs, the protection switch device 6 can be turned off to protect the battery cell 8.

[0056] In addition, the protection chip 1 can also obtain the voltage of the battery cell 8, compare the voltage with the voltage threshold, and determine whether the charging or discharging circuit is over-voltage. In the case of over-voltage, the protection switch device 5 can be turned off to protect the battery cell 8. Similarly, the battery fuel gauge 7 can also obtain the voltage of the battery cell 8, compare the voltage with the voltage threshold, and determine whether the charging or discharging circuit is over-voltage. In the case of over-voltage, the protection switch device 6 can be turned off to protect the battery cell 8.

[0057] It should be noted that the present embodiment only schematically describes the working process of the protection circuit in the battery, and in actual application, appropriate adjustments can be made according to specific scenarios.

[0058] based on Figure 2 The battery shown in the embodiment of the present disclosure also provides a method for obtaining the battery status. Figure 3 FIG. 1 is a flow chart showing a method for obtaining a battery status according to an exemplary embodiment. Figure 3 , a method for obtaining a battery status, which can be applied to a battery fuel gauge, includes steps 301 to 304, wherein:

[0059] In step 301, after the battery is switched to a rest mode, the voltage of the battery cell in the battery is obtained to obtain a first voltage.

[0060] In this embodiment, the battery may include multiple working modes, such as a static mode, a charging mode, or a discharging mode, which can be set according to specific scenarios and are not limited here.

[0061] In this embodiment, when the battery is in an initial mode, which includes a charging mode or a discharging mode, the battery can be switched to a static mode. Figure 4 , including: in step 401, the current of the precision resistor 3 can be detected in the initial mode, which is hereinafter referred to as the initial current for distinction. In step 402, it can be checked whether the initial current meets the preset condition. When the preset condition is met, the battery can be switched from the initial mode to the static mode. When the preset condition is not met, the current of the precision resistor 3 can be re-detected.

[0062] In one embodiment, it is determined whether the initial current meets the preset condition. Figure 5 , may include: in step 501, the current threshold and duration threshold in the initial mode may be obtained. For example, when the initial mode is the charging mode, the current threshold is Rest ChgI; when the initial mode is the discharging mode, the current threshold is Rest DsgI. For another example, the duration threshold may be Rest Time. It should be noted that the current threshold and duration threshold may be set according to the specific scenario and are not limited here. In step 502, it may be determined whether the initial current is less than the current threshold. In step 503, when the initial current is less than the current threshold, the duration is recorded; when the initial current is greater than the current threshold, the initial current is returned to be re-detected. In step 504, when the duration exceeds the duration threshold, it is determined that the initial current meets the preset conditions; when the duration is less than the duration threshold, it is determined that the initial current does not meet the preset conditions, and the initial current is returned to be re-detected.

[0063] Taking the charging mode as an example, the initial current Charge Current of the precision resistor 3 is detected to determine the size of the initial current Charge Current and the charging current threshold Rest ChgI. When the Charge Current is less than RestChgI, the duration Delay Time is recorded, and the Charge Current is re-detected when it is greater than Rest ChgI. When the Delay Time exceeds the Rest Time, it means that the Charge Current meets the preset conditions and the battery can be switched to the rest mode; when the Delay Time is less than the Rest Time, it means that the Charge Current does not meet the preset conditions and the Charge Current can be re-detected.

[0064] In this embodiment, after the battery is switched to the rest mode, the voltage of the battery cell 8 can be detected, which is hereinafter referred to as the first voltage Battery Voltage 1 for distinction. Figure 2 Taking the battery fuel gauge 7 as an example, the battery fuel gauge 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 to the ground and the positive electrode of the battery cell 8, respectively, and the voltage of the battery cell 8 can be obtained.

[0065] It should be noted that when the battery is in the rest mode, the first voltage of the battery cell 8 can be directly detected.

[0066] In step 302, the current in the precision resistor is detected in the static mode to obtain a static current.

[0067] In this embodiment, the current of the precision resistor 3 can be detected in the static mode to obtain the static current. The acquisition method is the same as the solution of the above embodiment, and will not be repeated here.

[0068] In step 303, when the static current meets a preset condition, the voltage of the battery cell is continuously acquired to obtain a second voltage.

[0069] In this embodiment, it is possible to determine whether the static current meets the preset condition. The determination method is the same as Figure 5 The principles of the embodiments shown are the same. For details, please refer to Figure 5 and Figure 5 The illustrated embodiments will not be described in detail here.

[0070] In this embodiment, when the static current meets the preset condition, the voltage of the battery cell 8 can continue to be obtained, which is hereinafter referred to as the second voltage Battery Voltage 2 for distinction.

[0071] In step 304, when the difference voltage between the second voltage and the first voltage is less than a difference threshold, the battery state is determined to be a normal state; when the difference voltage exceeds the difference threshold, the battery state is determined to be an abnormal state.

[0072] In this embodiment, the difference voltage Battery Voltage2-Battery Voltage 1 between the first voltage and the second voltage can be obtained. Battery Voltage 2-Battery Voltage 1 can represent the offset of Battery Voltage 2 and Battery Voltage 1. Then, the difference voltage (Battery Voltage 2-Battery Voltage 1) and the difference threshold Abnormal Delta Voltage can be compared. When Battery Voltage 2-Battery Voltage 1 is less than Abnormal Delta Voltage, it indicates that in the static mode, the two detected voltages are the same or similar, and the battery cell 8 does not have a discharge or charge problem, that is, the battery is in a normal state. When Battery Voltage 2-Battery Voltage 1 exceeds Abnormal Delta Voltage, it indicates that in the static mode, the two detected voltages are significantly different, and the battery cell 8 has a discharge or charge problem, that is, the battery is in an abnormal state.

[0073] In this embodiment, continue to refer to Figure 2After the battery fuel gauge 7 determines that the battery is in an abnormal state, it can also enable its own designated pin (INT) to close the protection switch device 6 electrically connected to the designated pin, thereby disconnecting the current charging or discharging circuit and protecting the battery cell 8.

[0074] In one embodiment, see Figure 2 , when the precision resistor 3 is short-circuited and the battery cell 8 has an internal short circuit, the initial current and the static current detected by the battery fuel gauge 7 are both 0, and the first voltage and the second voltage both exist. Considering that the internal short circuit of the battery cell 8 will consume power, the second voltage will be the first voltage, that is, Voltage 2-BatteryVoltage 1 is less than the Abnormal Delta Voltage. At this time, it can still be determined that the battery is in an abnormal state. In other words, this embodiment can detect the problem of internal short circuit of the battery cell 8 when the precision resistor 3 is short-circuited.

[0075] In one embodiment, see Figure 2 , when the protection chip 1 fails and the battery cell 8 has an internal short circuit, the battery fuel gauge 7 can still detect that the battery is in an abnormal state. In other words, the present embodiment can detect the problem of an internal short circuit in the battery cell 8 when the protection chip 1 fails. Compared with the related art, the present embodiment can use one less set of protection circuits, which is beneficial to reduce the number of protection devices in the battery and reduce production costs.

[0076] So far, in this embodiment, the battery is switched to the static 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 static mode, and the two voltages are equal or close, that is, the difference voltage is less than the difference threshold, and the battery is determined to be in a normal state. For another example, the battery may have an internal short circuit in the static mode, and the voltage will continue to drop, that is, the difference voltage will be greater than the difference threshold, and the battery is determined to be in an abnormal state. The battery can be subjected to a single fault test and an internal short circuit test to improve the protection performance of the battery while meeting the LPS requirements.

[0077] The following is the process of detecting the battery status in the charging mode. Figure 6, the battery charging current Charge Current can be detected by precision resistors, and the charging current Charge Current is compared with the charging current threshold RestChgI. If the Charge Current exceeds Rest ChgI, the charging current is re-detected. If the Charge Current is less than Rest ChgI, the duration Delay Time is recorded. After that, the duration Delay Time is compared with the duration threshold Rest Time. If Delay Time is less than Rest Time, the charging current is re-detected. If Delay Time exceeds RestTime, the battery is switched to the rest mode to detect the first voltage of the battery cell.

[0078] Continue to detect the static current of the battery and compare the static current with the current threshold. If the static current exceeds the current threshold Rest ChgI, re-detect the static current. If the static current is less than Rest ChgI, record the duration DelayTime. After that, compare the duration Delay Time with the duration threshold Rest Time. If Delay Time is less than RestTime, re-detect the charging current. If Delay Time exceeds Rest Time, detect the second voltage of the battery cell.

[0079] Obtain the difference voltage between the second voltage and the first voltage, compare the difference voltage with the difference voltage threshold, if the difference voltage is less than the difference voltage threshold, re-detect the static current, if the difference voltage exceeds the difference voltage threshold, determine that the battery is in an abnormal state, and the battery fuel gauge can enable the specified pin INT, turn off the protection switch 6, and disconnect the battery charging circuit to protect the battery cell 8.
