[0041] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0042] It should be understood that although the terms first, second, etc. may be used herein to describe various components, these components should not be limited by these terms. These terms are used to distinguish one component from another component. Therefore, the first component discussed below can be referred to as the second component without departing from the teachings of the concepts of the present application. As used herein, the term "and / or" includes any one of the associated listed items and all combinations of one or more.

[0043] Those skilled in the art will appreciate that the drawings are only schematic diagrams of example embodiments and may not be to scale. The modules or processes in the drawings are not necessarily required to implement the present application and therefore cannot be used to limit the scope of protection of the present application.

[0044] At present, the industry stipulates whether the battery is allowed to discharge based on whether the battery is connected to the system. The system consists of batteries and electronic devices. Discharging is allowed only when the battery is determined to be connected to the input terminal of the electronic device. Otherwise, the battery's C / D-MOS (Cascaded / Differential Metal-Oxide-Semiconductor) will be turned off.

[0045] However, the determination of whether the battery is connected to the system is based solely on the voltage detected by the pin of the IC connected to the input terminal of the electronic device. Due to the limitation of the hardware process technology, the high and low level conversion of the pin is not a uniform value, and can only guarantee a certain voltage value within a certain range.

[0046] When the voltage of the pin exceeds or falls below the threshold of the high-low level conversion, the high and low levels will be converted immediately. This may cause some problems. For example, if the battery has been connected to the input of the electronic device, but the pin voltage is abnormal due to external interference, it may trigger the computer to go offline abnormally, causing user complaints.

[0047] In view of this, an embodiment of the present application provides a battery offline detection method, which determines whether a high-low level conversion is required by preset a hysteresis voltage range. If the voltage detected by the detection pin is within this preset hysteresis voltage range, the high-low level conversion will not be performed, but the original state will be maintained without change. That is, even if the interference reaches the point where the pin high-low level conversion occurs, the pin will maintain the original level unchanged, thereby overcoming the problem of abnormal offline of the battery due to external interference, and further improving the situation of abnormal shutdown of the computer, so as to solve at least part of the above-mentioned technical problems.

[0048] See also Figure 1 , Figure 1 The overall process of a battery offline detection method provided in an embodiment of the present application. The battery is connected to an electronic device and discharges to the electronic device. The electronic device has a detection pin, and the detection pin is connected to the battery. The method includes the following steps:

[0049] Step 101: Determine that the initial level of the detection pin is a first level.

[0050] In step 101, it is necessary to first obtain the initial level of the detection pin. The detection pin is a pin connected to the IC of the electronic device, and the voltage detected by the detection pin is the basis for judging whether the battery is connected to the electronic device. The initial level of the detection pin can be the voltage detected by the detection pin before the battery is powered on after the IC leaves the factory, or the voltage detected by the detection pin when the electronic device is just powered on.

[0051] It should be noted that when the initial level of the detection pin is the voltage detected by the detection pin before the battery is powered on, the detection pin is at a low level, that is, the initial level of the detection pin is a first level, and the first level is a low level. Such a setting can ensure that when the battery is not powered on, the detection pin is in a known state so that the IC can correctly process and respond to input signals. When the initial level of the detection pin is the voltage detected by the detection pin when the electronic device is just powered on, the detection pin is at a low level or a high level, that is, the initial level of the detection pin is a first level, and the first level is a low level or a high level.

[0052] Step 102: If the real-time voltage of the detection pin is within the preset hysteresis voltage range, confirm that the level state of the detection pin maintains the first level.

[0053] Among them, electrical specification parameters play a key role in the design and manufacturing process of integrated circuits (ICs). Among them, the level threshold is an important indicator in the electrical specification parameters, which is used to determine the switching conditions of high and low levels. The level threshold refers to the voltage level that is identified as a high level or a low level in the input signal. When the real-time voltage of the detection pin is within the preset hysteresis voltage range, that is, between the high level threshold and the low level threshold, the IC will determine that the level state of the detection pin is the first level. The preset hysteresis voltage range is determined by the electrical specification parameters that come with the IC when it leaves the factory. This range is usually determined during the design and manufacturing process based on the characteristics and application requirements of the IC. It takes into account factors such as the operating voltage range, noise tolerance, and stability of the IC to ensure reliable level switching and signal processing. By using the preset hysteresis voltage range, the IC can provide a certain tolerance when the input signal fluctuates or noise exists, avoiding misjudgment and unstable level states. This ensures the reliability and stability of the IC under various environmental conditions, thereby achieving accurate signal processing and functional operation.

[0054] In some embodiments, the preset hysteresis voltage range includes a first voltage threshold and a second voltage threshold, which are two boundary values ​​of the preset hysteresis voltage range and are used to determine the switching conditions of the high and low levels. The first voltage threshold is one of the level thresholds in the electrical specification parameters of the IC. It represents the voltage level that is identified as a low level in the input signal. When the real-time voltage of the detection pin is lower than the first voltage threshold, the IC will determine that the level state of the detection pin is a low level. The second voltage threshold is also one of the level thresholds in the electrical specification parameters of the IC. It represents the voltage level that is identified as a high level in the input signal. When the real-time voltage of the detection pin is higher than the second voltage threshold, the IC will determine that the level state of the detection pin is a high level.

[0055] It should be noted that the second voltage threshold is usually greater than the first voltage threshold, in order to ensure that there is a sufficient hysteresis range during level switching to avoid misjudgment and unstable level state caused by fluctuations or noises of the input signal.

[0056] By defining a preset hysteresis voltage range and using a first voltage threshold and a second voltage threshold, the IC can provide a certain tolerance to adapt to different input signal conditions and environmental noise, thereby ensuring the reliability and stability of the IC in various situations, thereby achieving accurate level switching and signal processing.

[0057] In some embodiments, when the battery of the electronic device is not powered, the initial level of the detection pin is determined by the voltage of the detection pin. Typically, this initial level is defined as a first level, i.e., a low level. Such a setting can ensure that when the battery is not powered, the detection pin is in a known state so that the IC can correctly process and respond to input signals.

[0058] When the electronic device is powered on, the real-time voltage of the detection pin will change according to the change of the input signal. Within the preset hysteresis voltage range, that is, between the first voltage threshold and the second voltage threshold, the IC will determine that the level state of the detection pin is low. This setting allows a certain tolerance to adapt to fluctuations, noise or interference in the input signal, thereby ensuring accurate recognition and processing of low-level signals.

[0059] By defining a preset hysteresis voltage range and setting the initial level to the first level, a stable and reliable level state determination can be provided when the battery is not powered and after the electronic device is powered on. This setting helps ensure the normal operation and reliability of the system and avoids misjudgment and unstable level states caused by voltage changes or environmental noise during the power startup process.

[0060] In some embodiments, when the electronic device is just powered on, the detection pin detects a specific voltage, which is defined as the initial level of the detection pin. Typically, this initial level is called the first level, i.e., a low level. Such a setting can ensure that the detection pin is in a known state when the electronic device is just powered on, so that the IC can correctly process and respond to input signals.

[0061] When the electronic device is powered on, the real-time voltage of the detection pin will change with the input signal. Within the preset hysteresis voltage range, that is, between the first voltage threshold and the second voltage threshold, the IC will determine that the level state of the detection pin is low. This setting allows a certain tolerance to accommodate fluctuations, noise or interference in the input signal, thereby ensuring accurate recognition and processing of low-level signals.

[0062] By defining a preset hysteresis voltage range and setting the initial level to the first level, a stable and reliable level state determination can be provided when the electronic device is just powered on and after it is powered on. This setting helps ensure the normal operation and reliability of the system and avoids misjudgment and unstable level states caused by voltage changes or environmental noise during the power startup process.

[0063] In some embodiments, when the electronic device is just powered on, the detection pin detects a specific voltage, which is defined as the initial level of the detection pin. Different from the previous description, this initial level is set to the first level, that is, the high level. Such a setting can ensure that the detection pin is in a known state when the electronic device is just powered on, so that the IC can correctly process and respond to the input signal.

[0064] When the electronic device is powered on, the real-time voltage of the detection pin will change with the input signal. Within the preset hysteresis voltage range, that is, between the first voltage threshold and the second voltage threshold, the IC will determine that the level state of the detection pin is high. This setting allows a certain tolerance to adapt to fluctuations, noise or interference in the input signal, thereby ensuring accurate recognition and processing of high-level signals.

[0065] By defining a preset hysteresis voltage range and setting the initial level to the first level, a stable and reliable level state determination can be provided when the electronic device is just powered on and after it is powered on. This setting helps ensure the normal operation and reliability of the system and avoids misjudgment and unstable level states caused by voltage changes or environmental noise during the power startup process.

[0066] Step 103: If the real-time voltage of the detection pin meets the preset switching condition, the level state of the detection pin is controlled to switch from the first level to the second level, where the second level is different from the first level and is used to indicate that the battery is in an offline state.

[0067] The preset switching condition is that the real-time voltage of the detection pin is greater than the second voltage threshold or the real-time voltage of the detection pin is less than the first voltage threshold.

[0068] In some embodiments, when the battery is not powered, the initial level of the detection pin is set to a first level, and the first level is a low level. Such a setting can ensure that the detection pin is in a known state when the battery is not connected or powered, so that the IC can correctly process and respond to input signals. The preset switching condition is based on the comparison of the real-time voltage of the detection pin with the second voltage threshold. If the real-time voltage of the detection pin is greater than the second voltage threshold, it will be determined that the switching condition is met. When the preset switching condition is met, the corresponding control operation is performed to switch the level state of the detection pin from the first level to the second level. This switching can be used to indicate that the battery is in an offline state, that is, the battery is not connected or powered.

[0069] By defining a suitable second voltage threshold and preset switching conditions, the connection status of the battery can be accurately determined, and the level state of the detection pin can be changed accordingly. This can provide accurate battery status information and help the IC to perform corresponding processing and control to ensure the normal operation of the electronic device and the effective management of the battery.

[0070] In some embodiments, when the electronic device is just powered on, the detection pin detects a specific voltage, which is defined as the initial level of the detection pin. According to the description, the initial level is set to a first level, and the first level is a low level. Such a setting can ensure that the detection pin is in a known state when the electronic device is just powered on, so that the IC can correctly process and respond to the input signal. The preset switching condition is based on the comparison between the real-time voltage of the detection pin and the second voltage threshold. If the real-time voltage of the detection pin is greater than the second voltage threshold, it will be determined that the switching condition is met. When the preset switching condition is met, the corresponding control operation is performed to switch the level state of the detection pin from the first level to the second level. This switching can be used to indicate that the battery is in an offline state, that is, the battery is not connected or powered on.

[0071] By defining a suitable second voltage threshold and preset switching conditions, the connection status of the battery can be accurately determined, and the level state of the detection pin can be changed accordingly. This can provide accurate battery status information and help the IC to perform corresponding processing and control to ensure the normal operation of the electronic device and the effective management of the battery.

[0072] In some embodiments, when the electronic device is just powered on, the detection pin detects a specific voltage, which is defined as the initial level of the detection pin. According to the description, the initial level is set to a first level, and the first level is a high level. Such a setting can ensure that the detection pin is in a known state when the electronic device is just powered on, so that the IC can correctly process and respond to the input signal. The preset switching condition is based on the comparison between the real-time voltage of the detection pin and the first voltage threshold. If the real-time voltage of the detection pin is less than the first voltage threshold, it will be determined that the switching condition is met. When the preset switching condition is met, the corresponding control operation is performed to switch the level state of the detection pin from the first level to the second level. This switching can be used to indicate that the battery is in an offline state, that is, the battery is not connected or powered on.

[0073] By defining a suitable first voltage threshold and preset switching conditions, the connection status of the battery can be accurately determined, and the level state of the detection pin can be changed accordingly. This can provide accurate battery status information and help the IC to perform corresponding processing and control to ensure the normal operation of the electronic device and the effective management of the battery.

[0074] In view of this, the present embodiment has a determination of the first level, and when the real-time voltage of the detection pin is within the preset hysteresis voltage range, the level state of the detection pin will not switch, and will be maintained at the first level. Such a design takes into account other possible electrical signal interference to avoid abnormal battery offline due to voltage fluctuations. If the first level is a low level, the second level is a high level, and when the real-time voltage of the detection pin exceeds the second voltage threshold, the switching of high and low levels will occur, and the battery will be in an offline state. That is, when the detection pin is interfered by other electrical signals and the voltage of the detection pin fluctuates, the switching of high and low levels will not occur immediately, that is, the battery will not be abnormally offline, and when the voltage of the detection pin is greater than the second voltage threshold, the battery will be offline. If the first level is a high level, the second level is a low level, and when the real-time voltage of the detection pin is lower than the first voltage threshold, the switching of high and low levels will occur, and the battery will be in an offline state. That is, when the detection pin is interfered by other electrical signals and the voltage of the detection pin fluctuates, the high and low levels will not be switched immediately, that is, the battery will not be abnormally offline, and the battery will be offline only when the voltage of the detection pin is less than the first voltage threshold. Through this design, the present embodiment can effectively avoid voltage fluctuations caused by interference from other electrical signals during actual use, thereby avoiding abnormal offline conditions of the battery. This can improve the stability and reliability of the system, ensure that the electronic equipment can operate normally and effectively manage the status of the battery.

[0075] In some embodiments, see Figure 2 , Figure 2The present invention illustrates the steps for determining the first level when the first level of a battery offline detection method provided by an embodiment of the present application is a low level. The first level is a low level, and the second level is a high level; the preset hysteresis voltage range includes a first voltage threshold and a second voltage threshold, and the second voltage threshold is greater than the first voltage threshold.

[0076] Determining that the initial level of the detection pin is a first level includes the following steps:

[0077] Step 201: Obtaining the initial voltage of the detection pin;

[0078] Before the electronic device is powered on or just after it is powered on, measure the initial voltage of the detection pin.

[0079] Step 202: If the initial voltage of the detection pin is less than the first voltage threshold, determine that the initial level of the detection pin is a first level.

[0080] The measured initial voltage of the detection pin is compared with the first voltage threshold. If the initial voltage is less than the first voltage threshold, it is determined that the initial level of the detection pin is the first level, that is, a low level.

[0081] In view of this, through these steps, the initial level of the detection pin can be accurately determined. Such a setting helps the IC to correctly process and respond to input signals when the electronic device is just powered on, and provides an accurate basis for subsequent operations and controls. In implementation, it is necessary to select a suitable first voltage threshold according to specific application requirements and the characteristics of the electronic device. This ensures that the initial level of the detection pin can be accurately determined, and corresponding operations and controls can be performed as needed.

[0082] In some embodiments, see Figure 3 , Figure 3 The specific process of a battery offline detection method provided by an embodiment of the present application when the first level is a low level is illustrated. After the step of confirming that the level state of the detection pin maintains the first level, the embodiment further includes:

[0083] Step 104: If the real-time voltage of the detection pin is less than the first voltage threshold, confirm that the level state of the detection pin maintains the first level.

[0084] That is, when it is determined that the initial level of the detection pin is the first level and the first level is a low level, even during use, the real-time voltage of the detection pin is lower than the first voltage threshold, the level state of the detection pin remains in a low level state, and it will not trigger high and low level switching, that is, the battery will not go offline.

[0085] In view of this, when it is determined that the initial level of the detection pin is the first level and the first level is a low level, this embodiment can ensure that even if the voltage of the detection pin is lower than the first voltage threshold during use, the switching of the high and low levels will not be triggered immediately, thereby avoiding the abnormal offline of the battery. This design takes into account the misjudgment that may be caused by voltage fluctuations and interference, and ensures the stability and reliability of the system.

[0086] In some embodiments, see Figure 4 , Figure 4 The specific process of a battery offline detection method provided by an embodiment of the present application when the first level is a high level is illustrated. After the step of confirming that the level state of the detection pin maintains the first level, the present embodiment further includes:

[0087] Step 105: If the real-time voltage of the detection pin is greater than the second voltage threshold, confirm that the level state of the detection pin maintains the first level.

[0088] That is, when it is determined that the initial level of the detection pin is the first level and the first level is a high level, even during use, the real-time voltage of the detection pin is greater than the second voltage threshold, the level state of the detection pin remains in a high level state, and it will not trigger high and low level switching, that is, the battery will not go offline.

[0089] In view of this, when it is determined that the initial level of the detection pin is the first level and the first level is a high level, this embodiment can ensure that even if the voltage of the detection pin is greater than the second voltage threshold during use, the switching of the high and low levels will not be triggered immediately, thereby avoiding the abnormal offline of the battery. This design takes into account the misjudgment that may be caused by voltage fluctuations and interference, and ensures the stability and reliability of the system.

[0090] In some embodiments, see Figure 5 , Figure 5 A simple logic circuit between a detection pin and an IC of a battery offline detection method provided in an embodiment of the present application is illustrated. A switch 510 is provided on the circuit connecting the detection pin 520 and the electronic device, and one end of the switch 510 is grounded. When the detection pin 520 undergoes a high-low level conversion, the switch 510 receives a signal to close, and the battery is offline and does not discharge. When the switch 510 is in the open state, the battery can discharge normally.

[0091] In some embodiments, see Figure 6 , Figure 6 The specific process of a battery offline detection method provided in an embodiment of the present application is illustrated. The specific steps are as follows:

[0092] Determine whether the current voltage of the detection pin is less than the first voltage threshold, if so, the level state of the detection pin is at a low level, if not, proceed to the next step;

[0093] It is determined whether the current voltage of the detection pin is within a preset hysteresis voltage range. If not, the current voltage of the detection pin is greater than a second threshold value, and the level state of the detection pin is at a high level.

[0094] If the current voltage of the detection pin does not satisfy the condition that it is less than the first voltage threshold, it is determined whether the current voltage of the detection pin is within the preset hysteresis voltage range. If so, it is determined whether the level state of the detection pin is at a low level before the current voltage of the detection pin is within the preset hysteresis voltage range.

[0095] If it is at a low level, the level state of the detection pin is at a low level, and if it is at a high level, the level state of the detection pin is at a high level.

[0096] In some embodiments, see Figure 7 , Figure 7 Another specific process of a battery offline detection method provided in an embodiment of the present application is illustrated. The specific steps are as follows:

[0097] Determine whether the current voltage of the detection pin is greater than the second voltage threshold, if so, the level state of the detection pin is at a high level, if not, proceed to the next step;

[0098] It is determined whether the current voltage of the detection pin is within a preset hysteresis voltage range. If not, the current voltage of the detection pin is less than a first voltage threshold, and the level state of the detection pin is at a low level.

[0099] If the current voltage of the detection pin does not satisfy the condition that it is greater than the second voltage threshold, it is determined whether the current voltage of the detection pin is within the preset hysteresis voltage range.
