DETAILED DESCRIPTION

[0056] 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, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims. It should also be understood that the term "and / or" as used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0057] At present, with the improvement of the performance of electronic devices, the cycle of users replacing electronic devices is gradually increasing, and the storage time of electronic devices is gradually increasing. During the storage process of electronic devices, the internal battery will gradually release electrical energy until the battery is damaged, affecting the life of the electronic devices. Especially with the widespread application of silicon negative electrode batteries, in order to increase the battery life of electronic devices, the shutdown voltage of electronic devices is set lower and lower. The reduction in shutdown voltage will reduce the storage time of the battery and increase the risk of battery damage. Among them, the battery storage time refers to the voltage of the battery from the shutdown voltage to the voltage when it is damaged.

[0058] In the related art, a battery is provided, and the battery includes a battery protection circuit, a battery cell and a main control circuit. The battery cell is coupled to the main control circuit through the battery protection circuit. The battery protection circuit can prevent the battery from being overcharged, over-discharged and short-circuited by controlling the charging and discharging process of the battery. Specifically, during the charging process of the battery, when the battery voltage is greater than the overcharge protection voltage, the battery protection circuit will cut off the charging circuit to prevent the battery from being damaged by heating or even causing an explosion. During the discharging process of the battery, when the battery voltage is less than the over-discharge protection voltage, the battery protection circuit will cut off the discharge circuit to avoid damage due to over-discharge of the battery. Then, the battery storage time can be extended by the battery over-discharge protection voltage in the battery protection circuit. When the electronic device is turned off, the battery voltage drops to the over-discharge protection voltage, and the discharge circuit is cut off. After the discharge circuit is cut off, since there is no need for the battery to power the main control circuit, the speed at which the battery releases electrical energy can be reduced to a certain extent. However, in the production process of the battery, in order to prevent the load from mistakenly triggering the over-discharge protection function of the battery, the over-discharge protection voltage is usually set to a reference voltage and the reference voltage is low. Due to the low over-discharge protection voltage, the time before the discharge circuit is cut off is longer, and the reduced battery storage time leads to an increased risk of battery damage.

[0059] Based on this, the present disclosure provides a battery control method, device, electronic device and medium. By adjusting the battery over-discharge protection voltage according to the state of the electronic device and changing the voltage at which the battery stops supplying power, the time before the discharge circuit is cut off can be reduced to reduce the risk of battery damage. In this way, even if the shutdown voltage of the electronic device is reduced, by adjusting the over-discharge protection voltage of the battery, the storage time of the battery can still be extended to increase the storage time of the electronic device. Moreover, if the shutdown voltage of the electronic device is not reduced, the storage time of the battery can also be extended to increase the storage time of the electronic device by adjusting the over-discharge protection voltage.

[0060] For ease of understanding, the battery in the electronic device of the present disclosure is first described. Figure 1As shown, the battery includes a cell and a first protection circuit 10.

The first end of the first transistor T1 is coupled with the first end of the first resistor R1, the second end is coupled with the first end of the second transistor T2, and the control end is coupled with the discharge output terminal DO of the first protection circuit 10. The second end of the second transistor T2 is coupled to the voltage detection end VM of the first protection circuit 10 and the common end VSS of the main control circuit 20, and the control end is coupled to the charging output end CO of the first protection circuit 10. A first diode VD1 and a second diode VD2 are also provided at both ends of the first transistor T1 and the second transistor T2. The anode of the first diode VD1 is coupled to the first end of the first transistor T1, and the cathode is coupled to the second end of the first transistor T1. The first diode VD1 can be a body diode of the first transistor T1. The anode of the second diode VD2 is coupled to the second end of the second transistor T2, and the cathode is coupled to the first end of the second transistor T2. The second diode VD2 can be a body diode of the second transistor T2. A third resistor R3 is also provided between the voltage detection end VM of the first protection circuit 10 and the second end of the second transistor T2.

A second capacitor C2 and a third capacitor C3 are also provided between the control discharge end CTL and the ground end GND of the first protection circuit 10. When the voltage of the cell Cell is lower than the over-discharge protection voltage of the first protection circuit 10 , the first protection circuit 10 controls the first transistor T1 to be disconnected through the discharge output terminal DO, so as to disconnect the cell Cell from the main control circuit 20 to prevent the cell Cell from being over-discharged.

[0061] For example, Figure 2As shown, the battery also includes a second protection circuit 30. The power supply terminal VDD of the second protection circuit 30 is coupled to the positive electrode of the battery cell through the fourth resistor R4, the common terminal VSS is coupled to the ground terminal GND, and the current detection terminal VINI is coupled to the first end of the first resistor R1. A third transistor T3 and a fourth transistor T4 are also arranged between the negative electrode of the battery cell and the common terminal VSS of the main control circuit 20. The first end of the third transistor T3 is coupled to the first end of the first resistor R1, the second end is coupled to the first end of the fourth transistor T4, and the control end is coupled to the discharge output end DO of the second protection circuit 30. The second end of the fourth transistor T4 is coupled to the voltage detection end VM of the second protection circuit 30 and the first end of the first transistor T1, and the control end is coupled to the charging output end CO of the second protection circuit 30. A third diode VD3 and a fourth diode VD4 are also arranged at both ends of the third transistor T3 and the fourth transistor T4. The anode of the third diode VD3 is coupled to the first end of the third transistor T3, and the cathode is coupled to the second end of the third transistor T3. The third diode VD3 can be the body diode of the third transistor T3. The anode of the fourth diode VD4 is coupled to the second end of the fourth transistor T4, and the cathode is coupled to the first end of the fourth transistor T4. The fourth diode VD4 can be the body diode of the fourth transistor T4. A fifth resistor R5 is also provided between the voltage detection terminal VM of the first protection circuit 10 and the second end of the fourth transistor T4. A fourth capacitor C4 is also provided between the power supply terminal VDD and the ground terminal GND of the second protection circuit 30. When the voltage of the battery cell Cell is less than the over-discharge protection voltage of the second protection circuit 30, the second protection circuit 30 controls the third transistor T3 to be disconnected through the discharge output terminal DO to disconnect the battery cell Cell from the main control circuit 20 to avoid over-discharge of the battery cell Cell. By adding the second protection circuit 30, the battery cell Cell can be further protected when the first protection circuit 10 fails, thereby improving the reliability of battery protection.

[0062] For example, Figure 3As shown, the battery also includes a fuel gauge 40.

Among them, a fifth capacitor C5 is also provided between the enable terminal CE and the battery terminal BAT of the fuel gauge 40 and the ground terminal GND. A sixth capacitor C6 is also provided between the power supply sensing terminal BAT_SNS of the fuel gauge 40 and the ground terminal GND.

A first voltage regulator D1 is also provided between the clock transmission terminal SCL and the common terminal VSS of the main control circuit 20. A second voltage regulator D2 is also provided between the data transmission terminal SDA and the common terminal VSS of the main control circuit 20. Through the fuel gauge 40, the state of the battery cell Cell can be detected and sent to the main control circuit 20, so that the main control circuit 20 obtains the information of the battery cell Cell.

[0063] The present disclosure provides a battery control method, which can be applied to the above-mentioned circuit structure, such as Figure 4 As shown, the method includes:

[0064] S100: Determine the status of the electronic device.

[0065] S200: adjusting the over-discharge protection voltage of the battery according to the state of the electronic device.

[0066] In this embodiment, the state of the electronic device is determined to determine whether the electronic device needs to be powered by a battery. According to the state of the electronic device, the over-discharge protection voltage of the battery is adjusted to change the voltage at which the battery stops supplying power. By changing the voltage at which the battery stops supplying power, the power consumption of the electronic device during storage can be reduced, thereby reducing the risk of battery damage and increasing the storage time of the electronic device.

[0067] Exemplarily, the state of the electronic device determined in step S100 can be determined in the following manner: when the electronic device is turned on, the main control circuit will automatically power on and run. When the main control circuit is powered on and runs, it can be determined that the electronic device is in the power-on state. When the electronic device is turned off, the main control circuit will be powered off and stop running. When the main control circuit is powered off and stops running, it can be determined that the electronic device is in the power-off state. When the electronic device is in the power-on state, if the user has not used the electronic device for a long time, it can be determined that the electronic device is in the standby state. Alternatively, when the electronic device is in the power-on state, if the screen is in the screen-off state or the screen-off display state, it can also be determined that the electronic device is in the standby state. Alternatively, when the electronic device is in the power-on state, if the current flowing through the battery is small, it can also be determined that the electronic device is in the standby state. It can be understood that for determining the state of the electronic device in step S100, the above examples are only for illustration and not for limitation.

[0068] In one embodiment, in step 200, adjusting the over-discharge protection voltage of the battery according to the state of the electronic device can be determined in the following manner:

[0069] When the electronic device is in a shutdown state, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to a first voltage.

[0070] The first voltage is greater than the reference voltage.

[0071] In this embodiment, when the electronic device is in a shutdown state, since the main control circuit does not need to operate or only needs to operate in a low power consumption mode, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to a larger first voltage. Since the power consumption of the main control circuit is low and the electronic device is in a shutdown state, raising the over-discharge protection voltage will not affect the use of the electronic device. Then, by raising the over-discharge protection voltage to the first voltage, it is equivalent to increasing the voltage at which the battery stops supplying power to the main control circuit, thereby reducing the power consumed by the battery. Since the power consumed by the battery is reduced, the battery can be stored for a longer time after the electronic device is shut down to reduce the risk of battery damage, thereby increasing the storage time of the electronic device.

[0072] For example, the reference voltage may be an over-discharge protection voltage of a battery in the related art. For example, the reference voltage may be in the range of 2.4V to 2.6V. The reference voltage may be 2.45V, 2.5V, 2.55V, etc.

[0073] Exemplarily, the value of the first voltage may be between the reference voltage and the shutdown voltage of the electronic device. For example, the value range of the first voltage may be 2.7V to 2.9V. The first voltage may be 2.75V, 2.8V, 2.85V, etc.

[0074] In one embodiment, in the above step, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to the first voltage by:

[0075] A first signal is input to the control discharge terminal of the first protection circuit.

[0076] In this embodiment, by inputting the first signal to the control discharge terminal of the first protection circuit, the first protection circuit can adjust the over-discharge protection voltage to the first voltage, so as to reduce the loss of battery power and extend the storage time of the electronic device. Since the first signal is sent through the main control circuit, the battery control method is simple and no additional circuit is required, thereby reducing the complexity of the electronic device structure.

[0077] Exemplarily, the first signal may be a low level signal or a high level signal. When the electronic device is in a shutdown state, the main control circuit is in a stopped operation state or a low power consumption state. By inputting a low level signal to the control discharge terminal of the first protection circuit, the power consumption of the electronic device can be reduced, thereby further extending the storage time of the electronic device.

[0078] In one embodiment, after adjusting the over-discharge protection voltage of the first protection circuit in the battery to the first voltage in the above step, the battery control method further includes:

[0079] When the voltage of the battery is lower than the first voltage, the over-discharge recovery voltage of the first protection circuit is adjusted to the second voltage.

[0080] The second voltage is less than or equal to the reference voltage.

[0081] In this embodiment, when the voltage of the battery is less than the first voltage, the battery has entered the over-discharge protection state. If the electronic device needs to be operated, the battery needs to be restored from the over-discharge protection state to the normal operating state. If the battery needs to be restored from the over-discharge protection state to the normal operating state, on the one hand, the voltage of the battery needs to be greater than the over-discharge recovery voltage, and on the other hand, the main control circuit of the electronic device needs to be connected to the charging device to charge the battery. If the over-discharge recovery voltage of the first protection circuit is not adjusted, the over-discharge recovery voltage of the first protection circuit is greater than the reference voltage, and the battery needs to be charged for a certain period of time before it can be restored to the normal operating state. During the battery charging process, since the first transistor is in the off state, the charging current flows through the first diode. Because the tube voltage drop of the first diode is very high, the voltage at both ends of the battery will be falsely high, and the main control circuit will mistakenly believe that the battery voltage is high and charge the battery with a large current. When the battery voltage is small and the battery is charged with a large current, it is easy to cause battery damage. By adjusting the over-discharge recovery voltage, the over-discharge recovery voltage is made less than the reference voltage to avoid battery damage caused by high current charging, thereby reducing the risk of battery damage to increase the storage time of the electronic device.

[0082] For example, the second voltage may be in the range of 2.3V to 2.5V. The second voltage may be 2.35V, 2.4V, 2.45V, etc. The present disclosure provides a battery control method, such as Figure 5 As shown, the method includes:

[0083] S300: Determine the status of the electronic device.

[0084] S310: When the electronic device is in a shutdown state, adjust the over-discharge protection voltage of the first protection circuit in the battery to a first voltage.

[0085] S320, detecting the voltage of the battery.

[0086] S330: When the voltage of the battery is lower than the first voltage, adjust the over-discharge recovery voltage of the first protection circuit to a second voltage.

[0087] In this embodiment, the state of the electronic device is determined to determine the situation where the electronic device needs to be powered by a battery. When the electronic device is in a shutdown state, the main control circuit does not need to be operated or only needs to be operated in a low power consumption mode, and the battery does not need to power the main control circuit or uses less power. Since the power consumption of the main control circuit is low and the electronic device is in a shutdown state, increasing the over-discharge protection voltage will not affect the use of the electronic device. The over-discharge protection voltage of the first protection circuit in the battery is adjusted to a higher first voltage, so that the battery can switch the discharge circuit as soon as possible after the electronic device is shut down, reduce the electric energy released by the battery to increase the storage time of the electronic device. After the electronic device is shut down, the voltage of the battery is detected to determine whether the voltage of the battery is too low to trigger the over-discharge protection. When the voltage of the battery is less than the first voltage, the voltage of the battery is too low to trigger the over-discharge protection, and the over-discharge recovery voltage of the first protection circuit is adjusted to a smaller second voltage to avoid damaging the battery when charging the battery. By adjusting the over-discharge protection voltage and the over-discharge recovery voltage of the first protection circuit when the electronic device is shut down, the power consumption of the electronic device during the storage process can be reduced, thereby reducing the risk of battery damage to increase the storage time of the electronic device.

[0088] In one embodiment, in step 200, adjusting the over-discharge protection voltage of the battery according to the state of the electronic device may also be determined in the following manner:

[0089] When the electronic device is in a powered-on state, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to a third voltage.

[0090] The third voltage is less than or equal to the reference voltage.

[0091] In this embodiment, when the electronic device is in the power-on state, the load coupled to the main control circuit may suddenly change, causing the voltage of the battery to suddenly change. If the load coupled to the main control circuit suddenly becomes heavier, the voltage of the battery will suddenly drop to be lower than the first voltage. If the over-discharge protection voltage is maintained at the first voltage, the first protection circuit will cut off the discharge circuit between the battery and the main control circuit when the voltage of the battery is lower than the first voltage, causing the electronic device to shut down abnormally. By setting the over-discharge protection voltage to the third voltage, the electronic device is prevented from shutting down abnormally when it is in the power-on state, thereby improving the reliability of battery control.

[0092] Exemplarily, the third voltage may be in the range of 2.3 V to 2.5 V. The third voltage may be 2.35 V, 2.4 V, 2.45 V, etc.

[0093] In one embodiment, in the above step, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to the third voltage by:

[0094] A second signal is input to the control discharge terminal of the first protection circuit.

[0095] In this embodiment, by inputting the second signal to the control discharge terminal of the first protection circuit, the first protection circuit can adjust the over-discharge protection voltage to the third voltage to prevent the battery protection circuit from mistakenly cutting off the discharge circuit between the battery and the main control circuit. Since the second signal is sent through the main control circuit, the battery control method is simple and no additional circuit is required, thereby reducing the complexity of the electronic device structure.

[0096] Exemplarily, the second signal may be a low-level signal or a high-level signal, and the second signal and the first signal are signals with different levels.

[0097] In one embodiment, in the above step, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to the third voltage by:

[0098] Check the battery level.

[0099] When the power level of the battery is less than or equal to the preset power level, the over-discharge protection voltage of the first protection circuit is adjusted to a third voltage.

[0100] In this embodiment, when the electronic device is in the power-on state, the battery power is detected to determine the impact of the sudden change of the load on the battery voltage. If the battery power is greater than the preset power, the sudden change of the load will not cause the battery voltage to drop below the first voltage, and will not cause the discharge circuit to be mistakenly cut off, resulting in abnormal shutdown of the electronic device. Therefore, when the electronic device is in the power-on state and the battery power is greater than the preset power, the over-discharge protection voltage of the battery can be adjusted. Since the power consumption of the main control circuit is low when the first signal is a low-level signal, not adjusting the over-discharge protection voltage of the battery when the electronic device is in the power-on state can reduce the power consumption of the electronic device. When the electronic device is in the power-on state and the battery power is less than or equal to the preset power, if the over-discharge protection voltage is not adjusted, the sudden change of the load will cause the battery voltage to drop below the first voltage, causing the discharge circuit to be mistakenly cut off, resulting in abnormal shutdown of the electronic device. By adjusting the over-discharge protection voltage of the first protection circuit to a smaller third voltage, the mistaken cut-off of the discharge circuit can be avoided, thereby improving the reliability of battery control.

[0101] Exemplarily, the value range of the preset power may be 0% to 30%, or may be 5%, 10%, 15%, etc.

[0102] Exemplarily, in addition to determining whether to adjust the over-discharge protection voltage of the first protection circuit to the third voltage by detecting the power level of the battery, it is also possible to determine whether to adjust the over-discharge protection voltage of the first protection circuit to the third voltage by detecting the voltage of the battery.

[0103] In one embodiment, the voltage of the first signal is less than the voltage of the second signal. In step S200, adjusting the over-discharge protection voltage of the battery according to the state of the electronic device can also be determined in the following manner:

[0104] When the electronic device is in a standby state, the over-discharge protection voltage of the first protection circuit in the battery is adjusted to a first voltage.

[0105] In this embodiment, since the load coupled to the main control circuit will not change suddenly in the standby state, the magnitude of the over-discharge protection voltage will not cause abnormal shutdown of the electronic device. Since the voltage of the first signal is less than the voltage of the second signal, the first signal is a low-level signal, and the main control circuit outputs a low-level signal to reduce the power consumption of the electronic device. By adjusting the over-discharge protection voltage to the first voltage, the power consumption of the main control circuit can be reduced without affecting the use of the electronic device, thereby reducing the power consumption of the electronic device.

[0106] In one embodiment, before determining the state of the electronic device in step S100, the battery control method further includes:

[0107] The first protection circuit is configured to adjust the over-discharge protection voltage to the first voltage when the control discharge end receives the first signal.

[0108] The first protection circuit is configured to adjust the over-discharge protection voltage to a third voltage when the control discharge end receives the second signal.

[0109] In this embodiment, since the over-discharge protection voltage in the first protection circuit is set to a fixed value by default and cannot be adjusted, it is necessary to configure the over-discharge protection voltage of the first protection circuit before controlling the battery. By configuring the first protection circuit to adjust the over-discharge protection voltage to a corresponding voltage when receiving different signals at the control discharge end, the storage time of the electronic device can be increased while improving the reliability of battery control.

[0110] Exemplarily, when the first protection circuit receives the first signal at the control discharge end, the over-discharge protection voltage is adjusted to 2.8V; when the control discharge end receives the second signal, the over-discharge protection voltage is adjusted to 2.5V.

[0111] In one embodiment, the control discharge terminal of the first protection circuit in the battery is coupled to the main control circuit, and the over-discharge protection voltage of the first protection circuit is adjusted by inputting different level signals to the control discharge terminal of the first protection circuit.

[0112] In this embodiment, the main control circuit inputs different level signals to the control discharge terminal of the first protection circuit to adjust the overcurrent protection voltage of the first protection circuit, which can reduce the complexity of battery control and the complexity of the electronic device structure.

[0113] Exemplarily, when the main control circuit inputs a first signal to the first protection circuit, the first protection circuit adjusts the over-discharge protection voltage to the first voltage. When the main control circuit inputs a second signal to the first protection circuit, the first protection circuit adjusts the over-discharge protection voltage to the third voltage.

[0114] In one embodiment, the battery further includes a second protection circuit, and an over-discharge protection voltage of the second protection circuit is lower than the third voltage.

[0115] In this embodiment, by adding the second protection circuit to the battery, the battery can be protected when the first protection circuit is abnormal to avoid damage to the electronic device.

[0116] Exemplarily, the value range of the over-discharge protection voltage of the second protection circuit may be 2.2 V to 2.4 V. The value of the over-discharge protection voltage of the second protection circuit may be 2.25 V, 2.3 V, 2.35 V, etc.

[0117] The present disclosure provides a battery control method. Figure 6 As shown, the method includes:

[0118] S400: Determine the status of the electronic device.

[0119] S410: When the electronic device is in a shutdown state, adjust the over-discharge protection voltage of the first protection circuit in the battery to a first voltage.

[0120] S420: Detect the voltage of the battery.

[0121] S430: When the voltage of the battery is lower than the first voltage, adjust the over-discharge recovery voltage of the first protection circuit to a second voltage.

[0124] S460: When the power level of the battery is less than or equal to the preset power level, adjust the over-discharge protection voltage of the first protection circuit to a third voltage.

[0125] S470: When the electronic device is in a standby state, adjust the over-discharge protection voltage of the first protection circuit in the battery to a first voltage.

[0126] In this embodiment, when the electronic device is in the off state, by adjusting the over-discharge protection voltage, the storage time of the electronic device can be extended, and the problem of battery damage during the charging process can be avoided. When the electronic device is in the on state, by adjusting the over-discharge protection voltage, not only can the problem of abnormal shutdown of the electronic device be avoided, but also the power consumption of the electronic device can be reduced. When the electronic device is in the standby state, the power consumption of the electronic device can be reduced by adjusting the over-discharge protection voltage. At the same time, since the battery control method is applicable to batteries including only the first protection circuit, the first protection circuit and the second protection circuit, and the first protection circuit, the second protection circuit and the fuel gauge, the versatility of the battery control method can be improved.
