[0002] With the rapid development of electronic products and electric vehicles, lithium-ion batteries as energy storage devices, the battery life has become a highly concerned issue in today's society. Nowadays, after the battery is fully charged, if the charger is still in place, the charger will provide power to the electronic product or electric vehicle. The battery power is mainly consumed by the self-consumption of the battery cell, and the self-consumption rate of the battery cell is relatively slow (for example, it may take more than 30 days to consume the power from 100% to 98%). In addition, due to the characteristics of the battery cell, the longer the high power is stored, the greater the impact on the battery cell life. Therefore, how to reduce the battery cell power to extend the battery cell life when the battery cell is at a high power for a long time still needs to be explored. Summary of the Invention

In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0102] Figure 1 is an example diagram of a battery module according to an exemplary embodiment. Figure 1 As shown, the battery module includes:

[0103] Battery cell 1;

[0104] A power regulating component 2 connected to the battery cell 1;

[0105] The power meter 3 is connected to the power regulating component 2 and is used to detect the power of the battery cell 1 and control the power regulating component 2 to reduce the power of the battery cell 1 when the battery module is connected to an external charger and the power of the battery cell 1 is greater than a first preset power threshold.

[0106] In the embodiment of the present disclosure, the battery module includes a lithium-ion battery module and a lithium polymer battery module. The battery module includes a battery cell 1. The battery cell 1 is the most basic component of the battery and is usually an electrochemical device encapsulated in a metal shell. It is a unit for storing and releasing electrical energy, converting chemical energy into electrical energy through chemical reactions.

[0107] In the embodiment of the present disclosure, the power regulating component 2 is connected to the battery cell 1. The power regulating component 1 may be a circuit with a power regulating function, and in the embodiment of the present disclosure, it is mainly used to discharge the battery cell 1. The circuit of the power regulating component 1 may include components that can consume electric energy, such as fixed resistors and sliding rheostats. The power regulating component 2 may also include switches such as single-pole switches, double-pole switches, transistors, triodes, and metal-oxide-semiconductor field-effect transistors (MOSFETs). The power of the battery cell 1 is consumed by controlling the components that consume electric energy through the switches.

[0108] In the embodiment of the present disclosure, the fuel meter 3 detects the power of the battery cell 1. In some embodiments, the battery module may further include a voltage sampling component, which is connected to the battery cell 1 and the fuel meter 3 respectively; a current sampling component, which is connected to the battery cell 1 and the fuel meter 3 respectively; a temperature sampling component, which is at a distance from the battery cell 1 less than a preset distance threshold and is connected to the fuel meter 3. The fuel meter 3 obtains the voltage of the battery cell 1 based on the voltage sampling component, obtains the current of the battery cell 1 based on the current sampling component, obtains the temperature of the battery cell 1 based on the temperature sampling component, and determines the power of the battery cell 1 based on the voltage, current and temperature values.

[0109] In the embodiment of the present disclosure, a voltage sampling component is connected to the positive and negative poles of the battery cell 1. The voltage sampling component includes a voltage sampling chip, a resistor, an amplifier, and other components capable of detecting the voltage of the battery cell 1. The voltage sampling component is connected to the fuel gauge 3. The voltage sampling component obtains the voltage of the battery cell 1 and sends the voltage to the fuel gauge 3. A current sampling component is connected to the battery cell 1. The current sampling component may include a current sampling chip. The current of the battery cell 1 is obtained through the current sampling chip. The current sampling component may also include a current sensing resistor and a voltage sampling chip. The voltage sampling chip detects the voltage across the current sensing resistor and then obtains the current of the battery cell 1 based on the voltage across the current sensing resistor and the resistance value of the current sensing resistor. The current sampling component is connected to the fuel gauge 3. The current sampling component obtains the current of the battery cell 1 and sends the current to the fuel gauge 3. A temperature sampling component includes a thermistor, a thermocouple, an integrated temperature sensor, and other temperature sensors capable of detecting the temperature of the battery cell 1. The temperature sampling component is connected to the fuel gauge 3. The temperature sampling resistor obtains the temperature signal and sends the temperature signal to the fuel gauge 3. It should be noted that the distance between the temperature sampling component and the battery cell 1 is less than a preset distance threshold, which can better detect the temperature of the battery cell 1 and improve the accuracy of the detected temperature.

[0110] In the embodiment of the present disclosure, the fuel meter 3 can determine the power of the battery cell 1 based on the voltage, current and temperature values. The fuel meter 3 can calculate the power of the battery cell 1 based on the voltage, current and temperature through algorithms such as voltage lookup table method, coulomb counting method, termination voltage compensation method, impedance tracking algorithm, dynamic voltage correlation (Dynamic Voltage Correlation, DVC) algorithm, etc.

[0111] In the disclosed embodiment, the fuel meter 3 is connected to the power regulating component 2. When the battery module is connected to an external charger and the power level of the battery cell 1 is greater than a first preset power threshold, the fuel meter controls the power regulating component 2 to reduce the power level of the battery cell 1. In some embodiments, the battery module also includes other detection components to obtain electrical signal values ​​such as the voltage and current values ​​of the entire battery module to determine the connection status of the battery module and the charger. For example, the detection component can obtain the current signal value of the battery module. When the current signal value detected is greater than a preset current threshold, the battery module is determined to be connected to the external charger. When the current signal value detected is less than or equal to the preset current threshold, the battery module is determined to be disconnected from the external charger. In other embodiments, the fuel meter can determine the connection status of the battery module and the charger based on the obtained current and voltage values ​​of the battery cell 1. When it is determined that the battery module is connected to the external charger, the power level of the battery cell 1 is determined, and if the power level of the battery cell 1 is greater than the first preset power threshold, the fuel meter controls the power regulating component 2 to reduce the power level of the battery cell 1.

[0112] In the embodiment of the present disclosure, after the power meter 3 determines the power of the battery cell 1, it judges the relationship between the power and the first preset power threshold. The first preset power threshold is that when the battery module is connected to an external charger, the power of the battery cell 1 will affect the life of the battery cell 1 when it is greater than the first preset power threshold. The first preset power threshold can be an experimental value or a custom value, and the first preset power threshold can vary according to the specific situation. In some embodiments, the first preset power threshold can be adjusted according to the temperature range of the battery cell 1. For example, when it is detected that the temperature of the battery cell 1 is greater than or equal to 60°, the first preset power threshold can be set to 90%. When it is detected that the temperature of the battery cell 1 is greater than or equal to 48° and less than 60°, the first preset power threshold can be set to 95%.

[0113] In the embodiment of the present disclosure, the power meter 3 controls the power regulating component 2 to reduce the power of the battery cell 1 when it is determined that the battery module is connected to an external charger and the power of the battery cell 1 is greater than a first preset power threshold. As mentioned above, the power regulating component 2 may include a switch component and a component that consumes electric energy. The power meter 3 may be connected to the switch component in the power regulating component 2, and by controlling the switch component to be turned on or off, the power regulating component 2 that consumes electric energy is controlled to release the electric energy of the battery cell 1 to reduce the power of the battery cell 1. The power meter 3 may directly control the switch component in the power regulating component 2 to be turned on or off, or may control the switch component in the power regulating component 2 to be turned on or off through a control signal, such as controlling the switch component in the power regulating component 2 to be turned on or off through an output level signal. In some embodiments, the power regulating component 2 includes a single-pole switch. Then, when it is determined that the battery module is connected to an external charger and the power of the battery cell 1 is greater than a first preset power threshold, the power regulating component 2 may control the single-pole switch. The knife switch is turned on, thereby controlling the energy-consuming components in the power regulation component 2 to consume the energy of the battery cell 1 to reduce the energy of the battery cell 1; in other embodiments, the power regulation component 2 includes an N-type MOS transistor, and the power meter 3 is connected to the gate of the N-type MOS transistor. Then, when it is determined that the battery module is connected to an external charger and the energy of the battery cell 1 is greater than a first preset energy threshold, the power meter 3 outputs a high-level signal, thereby controlling the N-type MOS transistor to be turned on, and further controlling the energy-consuming components in the power regulation component 2 to consume the energy of the battery cell 1 to reduce the energy of the battery cell 1; in other embodiments, the power regulation component 2 includes a P-type MOS transistor, and the power meter 3 is connected to the gate of the P-type MOS transistor. Then, when it is determined that the battery module is connected to an external charger and the energy of the battery cell 1 is greater than the first preset energy threshold, the power meter 3 outputs a low-level signal, thereby controlling the P-type MOS transistor to be turned on, and further controlling the energy-consuming components in the power regulation component 2 to consume the energy of the battery cell 1 to reduce the energy of the battery cell 1.

[0114] In the embodiment of the present disclosure, the power level of the battery cell 1 is detected by the power meter 3, and when the battery module is connected to an external charger and the power level of the battery cell 1 is greater than a first preset power threshold, the power regulating component 2 is controlled to reduce the power level of the battery cell 1. This allows the power regulating component 2 to actively reduce the power level of the battery cell 1 when the battery module is connected to an external charger and the power level of the battery cell 1 is in a high power state, thereby reducing the time the battery cell 1 is in a high power state, reducing the aging speed of the battery cell 1, and extending the life of the battery cell 1, thereby extending the life of the battery.

[0115] In some embodiments, the power regulation component 2 includes a first switch and a first resistor, the first switch being connected to the power meter 3; the battery cell 1, the first resistor, and the first switch forming a first loop; the first end of the first resistor being connected to the positive electrode of the battery cell 1, and the second end of the first resistor being connected to the first switch;

[0116] The fuel meter 3 is used to generate a first control signal when the battery module is connected to an external charger and the power of the battery cell 1 is greater than the first preset power threshold; wherein the first control signal is used to turn on the first switch to reduce the power of the battery cell 1 through the first resistor in the first circuit.

[0117] In the embodiment of the present disclosure, the power regulation component 2 includes a first switch and a first resistor, wherein the first resistor is used to consume the electric energy of the battery cell 1, thereby reducing the power of the battery cell 1. As mentioned above, the first switch includes switches such as a single-pole switch, a double-pole switch, a transistor, a triode, and a MOS tube. The resistance value of the first resistor can be an experimental value or a set value, as long as it reaches a resistance value that can consume the electric energy of the battery cell 1. The embodiment of the present disclosure does not impose any restrictions on this.

[0118] In the embodiment of the present disclosure, the first switch is connected to the fuel meter 3 to receive the control signal of the fuel meter 3 to change the state. The first section of the first resistor is connected to the positive pole of the battery cell 1 so that when the conditions are met, the electric energy of the battery cell 1 can be consumed by the first resistor. The other end of the first resistor is connected to the first switch so that the first switch can control whether the first resistor consumes the electric energy of the battery cell 1. The first battery cell, the first resistor and the first switch form a first circuit. When the first switch is turned on, the first circuit is turned on, and the electric energy of the battery cell 1 can flow through the first circuit to achieve the effect of consuming the electric energy of the battery cell 1 through the first resistor.

[0119] In the embodiment of the present disclosure, the fuel gauge 3 is used to generate a first control signal when the battery module is connected to an external charger and the power level of the battery cell 1 is greater than a first preset power threshold. It should be noted that the first control signal includes a level signal, which can be a high level signal or a low level signal. The embodiment of the present disclosure does not limit this. The first control signal is associated with the first switch in the power regulation component 2. For example, when the first switch is an N-type MOS tube, the first control signal is a high level signal. When the first switch is a P-type MOS tube, the first control signal is a low level signal. When the above conditions are met, the fuel gauge 3 generates a first control signal, which is used to turn on the first switch to reduce the power level of the battery cell 1 through the first resistor in the first circuit.

[0120] In the embodiment of the present disclosure, when the battery module is connected to an external charger and the power level of the battery cell 1 is greater than a first preset power threshold, a first control signal is generated by the power meter 3 to control the conduction of the first switch, and then the power level of the battery cell 1 is reduced through the first resistor. This method is highly intelligent, simple and easy to implement.

[0121] In some embodiments, the first switch is a MOS transistor, and the power regulation component 2 further includes a second resistor; a first end of the second resistor is connected to the gate of the MOS transistor, and a second end of the second resistor is connected to the source of the MOS transistor;

[0122] The fuel gauge 3 is used to generate a second control signal when the battery module is not connected to the external charger or the power of the battery cell 1 is less than or equal to the first preset power threshold; wherein the second control signal is used to turn off the MOS tube.

[0123] In the embodiment of the present disclosure, the first switch is a MOS tube, and the power regulation component 2 further includes a second resistor. The first end of the second resistor is connected to the gate of the MOS tube, and the second end is connected to the source of the MOS tube. It should be noted that the MOS tube has three parasitic capacitors, namely, C connected to the MOS source and the drain of the MOS tube. DS , C connecting the MOS source and MOS gate GS And C connecting the MOS drain and the MOS gate GD Due to the existence of parasitic capacitance of MOS tube, when voltage is applied between the source and drain of MOS tube, the voltage applied between the source and drain of MOS tube will pass through C DS To C GS The MOS transistor is charged, so that the voltage on the MOS transistor gate is raised until the MOS transistor is turned on. Connecting a second resistor between the source and gate of the MOS transistor can effectively ensure the normal operation of the MOS transistor. First, when the gate of the MOS transistor is floating, the voltage between the source and drain of the MOS transistor will not cause the MOS transistor to be turned on and damaged. At the same time, when the first control signal from the fuel meter 3 is not received, the gate of the MOS transistor can be limited to a low level, reducing the possibility of the MOS transistor being mis-turned on and improving the reliability of the MOS transistor's on-off function.

[0124] In the embodiment of the present disclosure, the fuel gauge 3 generates a second control signal when the battery module is not connected to an external charger or detects that the power of the battery cell 1 is less than or equal to the first preset power threshold. The second control signal is used to turn off the MOS tube. It should be noted that the second control signal includes a level signal, which can be a high level signal or a low level signal. The embodiment of the present disclosure does not limit this. It is associated with the MOS tube in the power regulation component 2. For example, when the MOS tube is an N-type MOS tube, the second control signal is a low level signal. When the MOS tube is a P-type MOS tube, the second control signal is a high level signal.

[0125] In the embodiment of the present disclosure, by setting a second resistor between the source and gate of the MOS, the MOS tube can be protected from breakdown, the possibility of the MOS tube being mis-turned on is reduced, and the reliability of the on-off of the MOS tube is improved. When the battery module is not connected to an external charger or the power of the battery cell 1 is detected to be less than or equal to the first preset power threshold, the power meter 3 controls the MOS tube to be turned off, so as to control the first resistor not to reduce the power of the battery cell 1. When the power of the battery cell 1 is at a power level that will not affect the life of the battery, the power of the battery cell 1 will no longer be reduced, thereby storing the electrical energy of the battery cell 1 and providing electrical energy to other components.

[0126] In some embodiments, the battery module includes at least one protection component connected to the charge and discharge circuit of the battery cell 1 for protecting the battery cell 1 from overcharge and overdischarge.

[0127] In the disclosed embodiments, the battery module includes at least one protection component, which includes a protection chip and switch, a three-terminal fuse, a thermal fuse, a conventional current fuse, a slow-blow current fuse, a positive temperature coefficient thermistor (PTC), a negative temperature coefficient thermistor (NTC), a metal hybrid PTC (MHP), and the like, which can determine the charge and discharge status of the battery cell 1 based on the signal value (voltage, current, temperature) of the battery cell 1 and protect the battery cell 1 based on the status of the battery cell 1. In some embodiments, the protection component includes a protection chip and a MOS transistor. The protection chip detects the voltage or current value of the battery cell, determines the charge and discharge status of the battery cell 1 based on the voltage or current value, and controls the MOS transistor based on the status to protect the battery cell 1. In other embodiments, the protection component is a PTC. The PTC detects the current value of the battery cell 1 and changes its resistance value based on the current value to protect the battery cell 1 when an overcurrent occurs.

[0128] The embodiment of the present disclosure provides at least one protection component to protect the battery cell 1 from overcharge and over-discharge, and can protect the battery cell 1 when overcharge or over-discharge occurs, thereby improving the safety performance of the battery cell 1 and extending the life of the battery cell 1. When the number of protection components is greater than 1, if one of the protection components fails, the other protection component can continue to protect the battery cell 1, thereby extending the life of the battery cell 1.

[0129] In some embodiments, the protection component includes a protection chip, a second switch and a third switch connected to the charge and discharge circuit; wherein, the protection chip is used to monitor the electrical parameter value on the charge and discharge circuit of the battery cell, and control the second switch to be turned off for overcharge protection when the electrical parameter value meets the first preset parameter condition; and control the third switch to be turned off for over-discharge protection when the electrical parameter value meets the second preset parameter condition.

[0130] As mentioned above, the protection component may include a protection chip and a switch. In the embodiment of the present disclosure, the protection component includes a protection chip, a second switch and a third switch connected to the charge and discharge circuit of the battery cell 1, and the protection chip can monitor the electrical parameter value on the charge and discharge circuit of the battery cell 1. The protection chip determines the charge and discharge status of the battery cell 1 based on the electrical parameter value, wherein the electrical parameter value can be the voltage value of the charge and discharge circuit of the battery cell 1, or it can be the current value of the discharge circuit of the battery cell 1, and the embodiment of the present disclosure does not limit this.

[0131] In the embodiment of the present disclosure, the protection component may also include a pull-up resistor and a capacitor, wherein the pull-up resistor is used to limit the current flowing into the protection component from the battery cell 1, thereby extending the life of the protection component and providing better protection for the battery cell 1; the capacitor is used to filter the interference signal transmitted from the battery cell 1 to the protection chip when the battery cell 1 is interfered with, thereby enabling the protection chip to operate normally, and can be used to weaken the conduction of current fluctuations of the protection chip to the battery cell 1 when the protection chip is instantly started or the operating frequency is switched, thereby better protecting the battery cell 1 and extending the life of the battery cell 1.

[0132] In the embodiment of the present disclosure, the second switch and the third switch include switches such as a single-pole switch, a double-pole switch, a transistor, a triode, and a MOS tube. The protection chip controls the second switch to be turned off for overcharge protection when the electrical parameter value meets the first preset parameter condition. The electrical parameter value meets the first preset parameter condition when the electrical parameter value exceeds the electrical parameter value of the battery cell 1 in a normal charging state. For example, when the electrical parameter value is the voltage value on the charge and discharge circuit of the battery cell 1, the second switch is controlled to be turned off to cut off the charging circuit of the battery cell 1 when the voltage value is greater than the overcharge cut-off voltage of the battery cell 1, wherein the overcharge cut-off voltage can be the factory setting value of the battery cell 1 or an experimental value; the protection chip controls the third switch to be turned off for over-discharge protection when the electrical parameter value meets the second preset parameter condition. The electrical parameter value meets the second preset parameter condition when the electrical parameter value is lower than the electrical parameter value of the battery cell 1 in a normal discharge state. For example, when the electrical parameter value is the voltage value on the charge and discharge circuit of the battery cell 1, the third switch is controlled to be turned off to cut off the discharge circuit of the battery cell 1 when the voltage value is less than the over-discharge cut-off voltage of the battery cell 1, wherein the over-discharge cut-off voltage can be the factory setting value of the battery cell 1 or an experimental value.

[0133] In some embodiments, the second switch and the third switch are both MOS tubes, and the second switch and the third switch further include parasitic diodes. The parasitic diodes are used to form a discharge circuit when the second switch is turned off, or to form a charging circuit when the third switch is turned off. The parasitic diodes can also divert current when a large instantaneous reverse current is generated in the circuit to protect the MOS tube.

[0134] In the embodiment of the present disclosure, by setting the protection chip, the second switch, and the third switch, when the battery cell 1 is overcharged or over-discharged, the protection chip can control the second switch or the third switch to cut off the charging circuit or the discharging circuit of the battery cell 1, thereby protecting the battery cell 1 and improving the safety performance and service life of the battery cell 1.

[0135] Figure 2 FIG. 1 is a diagram showing an example of an internal circuit of a battery module according to an exemplary embodiment. Figure 2As shown, the current-sense resistor is a current sampling component used to obtain the current of the battery cell 1 and send it to the fuel gauge 3. The fuel gauge 3 calculates the power of the battery cell 1 and, if it determines that the battery module is connected to an external charger and the power of the battery cell 1 is greater than or equal to a first preset power threshold, outputs a high-level signal to control the N-MOS transistor Q1 to turn on. Resistors R1 and R2, and the N-MOS transistor Q1 are part of the power regulation component 2. Resistor R1 is a first resistor used to reduce the power of the battery cell 1 when the MOS transistor Q1 is turned on. The N-MOS transistor Q1 is a first switch used to turn on or off according to the level signal of the fuel gauge 3. When the MOS transistor Q1 is turned on, a loop is formed consisting of the positive electrode of the battery cell 1 - resistor R1 - N-MOS transistor Q1 - current-sense resistor - negative electrode of the battery cell 1, so that resistor R1 reduces the power of the battery cell 1. Resistor R2 is a second resistor used to control the N-MOS transistor Q1 to turn off when the fuel gauge outputs a low level, reducing the possibility of the N-MOS transistor Q1 being mis-turned on. The N-MOS transistor Q1 also includes a parasitic diode to protect the MOS transistor. The first-level protection chip, the second-level protection chip and the connected resistors, capacitors and MOS tubes are all protection components. The first-level protection chip obtains the voltage between the output voltage and the reference voltage to determine the voltage of the battery cell 1, and controls the discharge MOS tube 1 and the charge MOS tube 1 according to the voltage to protect the battery cell 1. Among them, the current limiting resistor 1 is used to limit the current flowing from the battery cell 1 to the first-level protection chip to reduce the possibility of damage to the first-level protection chip. The capacitor C1 is used to filter the interference signal and weaken the reverse conduction; the second-level protection chip obtains the voltage between the output voltage and the reference voltage to determine the voltage of the battery cell 1, and controls the discharge MOS tube 2 and the charge MOS tube 2 ... Resistor 2 is used to limit the current flowing from the battery cell 1 to the secondary protection chip to reduce the possibility of damage to the secondary protection chip. Capacitor C2 is used to filter interference signals and weaken reverse conduction. As can be seen from the figure, the discharge MOS tube 1 and the charge MOS tube 1 also include parasitic diodes for protecting the MOS tubes and continuing to charge the battery cell 1 when the discharge MOS tube 1 is turned off, and continue to discharge the battery cell 1 when the charge MOS tube 1 is turned off; the discharge MOS tube 2 and the charge MOS tube 2 also include parasitic diodes for protecting the MOS tubes and continuing to charge the battery cell 1 when the discharge MOS tube 2 is turned off, and continue to discharge the battery cell 1 when the charge MOS tube 2 is turned off.

[0136] Figure 3 is a flow chart of a control method according to an exemplary embodiment. Figure 3 As shown, the following steps are included:

[0137] S11, detecting whether the electronic device is connected to an external charger;

[0138] S12, detecting the power level of the battery cells in the electronic device by using a power meter in the electronic device;

[0139] S13: In response to the electronic device being connected to the external charger and the power level of the battery cell being greater than a first preset power threshold, controlling a power regulating component in the electronic device through the power meter to reduce the power level of the battery cell.

[0140] In the embodiments of the present disclosure, the control method can be applied to electronic devices including the above-mentioned battery module, such as user equipment (UE), mobile devices, user terminals, mobile phones, tablet computers, personal digital assistants (PDAs), handheld devices, computing devices, vehicle-mounted devices, wearable devices, smart cars, rechargeable cars, vehicle-mounted computers, etc.

[0141] In step S11, it is detected whether the electronic device is connected to an external charger. The electronic device may include a detection chip, a central processing unit (CPU), a microprocessor unit (MPU), a system on chip (SOC), or other chips to detect electrical parameter values ​​of the electronic device, and determine whether the electronic device is connected to the external charger based on the electrical parameter values, where the electrical parameter values ​​include current values, voltage values, temperature values, etc.

[0142] In step S12, the electronic device detects the amount of electricity in the battery cell 1 in the electronic device through the fuel gauge 3 in the electronic device. As mentioned above, the fuel gauge 3 can obtain the voltage of the battery cell 1 based on the voltage sampling component, obtain the current of the battery cell 1 based on the current sampling component, and obtain the temperature of the battery cell 1 based on the temperature sampling component, and then determine the amount of electricity in the battery cell 1 based on the voltage, current and temperature values. The fuel gauge 3 can calculate the amount of electricity in the battery cell 1 based on the voltage, current and temperature through algorithms such as voltage lookup table method, coulomb counting method, termination voltage compensation method, impedance tracking algorithm, dynamic voltage correlation (Dynamic Voltage Correlation, DVC) algorithm. It should be noted that in some embodiments, the electronic device can also detect the amount of electricity in the battery cell 1 through other components. For example, the electronic device can also include a power management module, detect the amount of electricity through the power management module, and send the amount of electricity to the fuel gauge 3; in other embodiments, the electronic device can also monitor the amount of electricity through an installed software application and send the amount of electricity to the fuel gauge 3.

[0143] In step S13, in response to the electronic device being connected to an external charger and the power level of the battery cell 1 being greater than a first preset power threshold, the power regulating component 2 in the electronic device is controlled by the power meter 3 to reduce the power level of the battery cell 1. As mentioned above, when the battery module is connected to an external charger, the power level of the battery cell 1 will affect the life of the battery cell 1 when it is greater than the first preset power threshold. The first preset power threshold can be an experimental value or a custom value, and the first preset threshold can vary according to specific circumstances. In some embodiments, the first preset power threshold can be adjusted according to the temperature range of the battery cell 1. For example, when it is detected that the temperature of the battery cell 1 is greater than or equal to 60°, the first preset power threshold can be set to 90%. When it is detected that the temperature of the battery cell 1 is greater than or equal to 48° and less than 60°, the first preset power threshold can be set to 95%.

[0144] In the embodiment of the present disclosure, the power regulating component 2 may include components such as resistors and loads that can consume the power of the battery cell 1. The power regulating component is controlled by the power meter 3 so that the components in the power regulating component 2 that can consume the power of the battery cell 1 consume the power of the battery cell 1, thereby reducing the power of the battery cell 1.

[0145] In the embodiment of the present disclosure, based on whether the electronic device is connected to an external charger and the relationship between the power level of the battery cell 1 in the electronic device and the first preset power threshold, the power meter 3 is used to control the power regulation component 2 to reduce the power level of the battery cell 1. This allows the power regulation component 2 to actively reduce the power level of the battery cell 1 when the electronic device is connected to an external charger and the power level of the battery cell 1 is in a high power state, thereby reducing the time that the battery cell 1 is in a high power state, reducing the aging rate of the battery cell 1, and extending the life of the battery cell 1, thereby extending the life of the battery.

[0146] In some embodiments, the method further comprises:

[0147] Detecting the temperature of the battery cell by the fuel gauge 3;

[0148] Determining, based on the temperature of the battery cell 1 and the amount of electricity in the battery cell 1 , factors affecting the life of the battery cell 1 by the temperature and the amount of electricity;

[0149] In response to the electronic device being connected to the external charger and the power level of the battery cell 1 being greater than a first preset power threshold, controlling the power regulating component 2 in the electronic device to reduce the power level of the battery cell 1 through the power meter 3 includes:

[0150] In response to the electronic device being connected to the external charger and the power level of the battery cell 1 being greater than the first preset power threshold, determining a control signal output by the power meter 3 according to the influencing factor;

[0151] In response to the control signal being a signal that meets a preset condition, the power regulating component 2 is controlled by the power meter 3 to reduce the power of the battery cell 1 .

[0152] In the embodiment of the present disclosure, as mentioned above, the fuel gauge 3 can detect the temperature of the battery cell 1 through the temperature sampling component, and determine the influence factors of the temperature and the power on the life of the battery cell based on the temperature of the battery cell 1 and the power of the battery cell 1. In some embodiments, the influence factor on the life of the battery cell 1 can be determined according to the product of the temperature of the battery cell 1 and the power of the battery cell 1; in other embodiments, the influence factor on the life of the battery cell 1 can be determined according to the sum of the temperature of the battery cell 1 and the power of the battery cell 1; in other embodiments, the influence weight can be determined based on the temperature of the battery cell 1, and the influence factor can be determined according to the product of the influence weight and the time period during which the power of the battery cell 1 is greater than the first preset power threshold.

[0153] In an embodiment of the present disclosure, in response to the electronic device being connected to an external charger and the power level of the battery cell 1 being greater than a first preset power threshold, the control signal output by the power meter 3 is determined based on the influencing factor. The control signal can be a level signal, specifically a high level signal or a low level signal, and the embodiment of the present disclosure does not impose any restrictions on this.

[0154] In an embodiment of the present disclosure, in response to a control signal being a signal that meets a preset condition, the power regulating component 2 is controlled by the power meter 3 to reduce the power of the battery cell 1, wherein the control signal is a signal that causes the component in the power regulating component 2 that can consume electrical energy to reduce the power of the battery cell 1. For example, the control signal being a signal that meets the preset condition is a signal that can turn on the first switch in the power regulating component 2, which is specifically related to the first switch in the power regulating component 2. In some embodiments, the first switch in the power regulating component 2 is an N-MOS tube, and the signal of the preset condition is a high-level signal; in other embodiments, the first switch in the power regulating component 2 is a P-MOS tube, and the signal of the preset condition is a low-level signal.

[0155] In the embodiment of the present disclosure, an influencing factor is determined based on the power of the battery cell 1 according to the thermometer of the battery cell 1, and a control signal of the power meter 3 is determined based on the influencing factor. Finally, the power regulating component 2 is controlled according to the control signal to reduce the power of the battery cell 1. This is highly intelligent while being able to reduce the time the battery cell 1 is in a high power state and extend the life of the battery cell 1.

[0156] In some embodiments, determining the influencing factors of temperature and power on the life of the battery cell 1 based on the temperature of the battery cell 1 and the power of the battery cell 1 includes:

[0157] Determining an impact weight based on a temperature range in which the temperature of the battery cell 1 is located;

[0158] The impact factor is determined based on the impact weight and the duration during which the power of the battery cell 1 is within a preset power range.

[0159] In the embodiment of the present disclosure, the influence weight is determined based on the temperature range of the battery cell 1, wherein different temperature ranges correspond to different influence weights. In some embodiments, the influence weight is positively correlated with the temperature within the temperature range, such as when the temperature is greater than or equal to 60°, the influence weight is 30, and when the temperature is less than 60° and greater than or equal to 48°, the influence weight is 10; in other embodiments, the influence weight is negatively correlated with the temperature within the temperature range, such as when the temperature is greater than or equal to 60°, the influence weight is 10, and when the temperature is less than 60° and greater than or equal to 48°, the influence weight is 5.

[0160] In the embodiment of the present disclosure, the influence factor is determined based on the influence weight and the duration that the charge of the battery cell 1 is within the preset charge range. In some embodiments, the influence factor is the product of the influence weight and the duration that the charge of the battery cell 1 is within the preset charge range; in other embodiments, the influence factor is the sum of the influence weight and the duration that the charge of the battery cell 1 is within the preset charge range; in other embodiments, the influence factor is the duration that the charge of the battery cell 1 is within the preset charge range divided by the influence weight. The embodiment of the present disclosure does not impose any restrictions on this.

[0161] It should be noted that high temperature will cause the chemical reaction rate inside the battery cell 1 to accelerate, thereby accelerating the aging and degradation of the battery cell 1. Therefore, the preset power range corresponding to different temperature ranges is different. In some embodiments, the temperature in the temperature range is negatively correlated with the lower limit of the power in the preset power range. For example, when the temperature is greater than or equal to 60°, the preset power range is 100% to 90%; when the temperature is less than 60° and greater than or equal to 48°, the preset power range is 100% to 95%.

[0162] The following table shows an exemplary embodiment of how to calculate the impact factor based on temperature and power:

[0163]

[0164]

[0165] In the embodiment of the present disclosure, an influence weight is first determined according to the temperature of the battery cell 1, and then an influence factor is determined based on the influence weight and the duration that the power of the battery cell 1 is within a preset power range. This method can control the power of the battery cell 1 to be within different power ranges according to the temperature of the battery cell 1, so that when the temperature is low and the chemical reaction speed inside the battery cell 1 is slow, the power regulation component 2 is not triggered to reduce the power of the battery cell 1. This method can better store the power of the battery cell 1 and supply power to other loads, and is highly intelligent.

[0166] In some embodiments, the method further comprises:

[0167] Detecting the current of the battery cell 1 by the fuel gauge 3;

[0168] The determining, based on the temperature of the battery cell 1 and the amount of electricity in the battery cell 1 , the factors affecting the life of the battery cell 1 by the temperature and the amount of electricity in the battery cell 1 , includes:

[0169] In response to the duration of the current within the first preset current threshold range being greater than or equal to the first preset time threshold, based on the temperature of the battery cell 1 and the charge of the battery cell 1, the influence factors of temperature and charge on the life of the battery cell 1 are determined.

[0170] In the embodiment of the present disclosure, the current of the battery cell 1 is detected by the fuel meter 3. As mentioned above, the fuel meter 3 can detect the current of the battery cell 1 based on the current sampling component. The current sampling component includes a current sampling chip, a current detection resistor and other components that can detect the current of the battery cell 1.

[0171] In an embodiment of the present disclosure, in response to the duration of the current within the first preset current threshold range being greater than or equal to the first preset time threshold, the influence factors of temperature and power on the life of the battery cell 1 are determined based on the temperature of the battery cell 1 and the power of the battery cell 1, wherein the first preset current threshold range is the current threshold range when the battery cell 1 is working normally, and the first preset current threshold range is a set threshold range, which can be measured through experiments, or can be the factory setting of the electronic device, or can be set manually. In this regard, the embodiment of the present disclosure does not impose any restrictions, such as the first preset current threshold range is (-20mA, 5mA); the first preset time threshold is also a set threshold, which can be measured through experiments, or can be the factory setting of the electronic device, or can be set manually, such as the first time threshold is 60 seconds.

[0172] In the embodiment of the present disclosure, the state of the battery cell 1 can be determined by first determining the current of the battery cell 1, wherein the state of the battery cell 1 may be that the battery cell 1 is providing power to the load, that the battery cell 1 is operating normally, or that the battery cell 1 is damaged. In the embodiment of the present disclosure, the state of the battery cell 1 is determined first, and then the influencing factor is determined according to the temperature and the power, so as to control the power regulating component 2 to reduce the power of the battery cell 1, which is highly intelligent.

[0173] In some embodiments, the method further comprises:

[0174] In response to the current being less than a lower limit current in the first preset current threshold range, or being greater than an upper limit current in the first preset current threshold range, setting the impact factor to a preset value; and / or,

[0175] In response to the temperature of the battery cell 1 being lower than the lower limit temperature of the temperature range, setting the impact factor to a preset value; and / or,

[0176] In response to the power level of the battery cell 1 being less than the first preset power threshold, the impact factor is set to a preset value.

[0177] In the embodiment of the present disclosure, in response to the current being less than the lower limit current in the first preset current threshold range, or being greater than the upper limit current in the first preset current threshold range, the impact factor is set to a preset value. As previously mentioned, the first current threshold range is a set threshold range. For example, if the first preset current threshold range is set to [-20mA, 5mA], then the lower limit current in the first preset current threshold range is -20mA, and the upper limit current in the first preset current threshold range is 5mA. It should be noted that the first preset current threshold range is the current threshold range when the battery cell 1 is operating normally. When the current is less than the lower limit current in the first preset current threshold range, it means that the battery cell 1 is already supplying power to other loads and there is no need to reduce the power of the battery cell 1 through the power regulation component 2. When the current is greater than the upper limit current in the first preset current threshold range, it means that the battery cell 1 is in an abnormal working state and may be damaged, and the power of the battery cell 1 cannot be reduced by the power regulation component 2. In the embodiment of the present disclosure, the preset value can be a pre-set value or a factory set value, and the embodiment of the present disclosure does not limit this. For example, the preset value can be 0.

[0178] In the embodiment of the present disclosure, in response to the temperature of the battery cell 1 being lower than the lower limit temperature in the temperature range, the influence factor is set to a preset value; in response to the power of the battery cell 1 being lower than the first preset power threshold, the influence factor is set to a preset value, the temperature range is a set range, which can be measured through experiments or set manually, and the lower limit temperatures of different temperature ranges are different. For example, when the temperature range of the battery cell 1 is greater than or equal to 60°, the lower limit temperature in the temperature range is 60°, and when the temperature range of the battery cell 1 is [48°, 60°], the lower limit temperature in the temperature range is 48°; as mentioned above, the first preset power threshold can be an experimental value or a custom value, such as 90% or 95%.

[0179] It should be noted that when the temperature of the battery cell 1 is lower than the lower limit temperature in the temperature range, and / or the power of the battery cell 1 is lower than the first preset power threshold, it means that the temperature or power at this time will not affect the life of the battery cell 1, so there is no need to reduce the power of the battery cell 1 through the power regulation component 2 to extend the life of the battery cell 1.

[0180] In the embodiment of the present disclosure, in response to the current being less than the lower limit current in the first preset current threshold range, or being greater than the upper limit current in the first preset current threshold range; and / or in response to the temperature of the battery cell 1 being less than the lower limit temperature in the temperature range; and / or in response to the charge of the battery cell 1 being less than the first preset charge threshold, the influence factor is set to a preset value. This allows the electric energy of the battery cell 1 to be stored and provided to other loads on the basis that the current, temperature and charge will not affect the life of the battery cell 1. The setting of the influence factor to a preset value can also reduce the possibility of the previously calculated influence factor affecting the subsequent control process, and is more intelligent.

[0181] In some embodiments, in response to the electronic device being connected to the external charger and the power level of the battery cell being greater than the first preset power threshold, determining the control signal output by the fuel gauge according to the influencing factor includes:

[0182] In response to the electronic device being connected to the external charger, the power level of the battery cell being greater than the first preset power threshold, and the impact factor being greater than or equal to the preset impact factor threshold, determining that the fuel gauge outputs a first control signal;

[0183] In response to the control signal being a signal that satisfies a preset condition, controlling the power regulating component to reduce the power of the battery cell through the power meter includes:

[0184] In response to the control signal being the first control signal, the power regulating component is controlled by the power meter to reduce the power of the battery cell.

[0185] In an embodiment of the present disclosure, in response to the electronic device being connected to an external charger, the power level of the battery cell 1 being greater than a first preset power threshold, and the impact factor being greater than or equal to the preset impact factor threshold, the power meter 3 is determined to output a first control signal, wherein the preset impact factor threshold is a set value, which may be an experimental value or a manually set value, and the embodiment of the present disclosure does not impose any limitation on this. As mentioned above, the first control signal includes a level signal. Specifically, the first control signal may be a high-level signal or a low-level signal, and the embodiment of the present disclosure does not impose any limitation on this.

[0186] In the embodiment of the present disclosure, the control signal output by the power meter 3 is a first control signal, and the power regulating component 2 is controlled by the power meter 3 to reduce the power of the battery cell 1 .

[0187] The embodiment of the present disclosure determines that the power meter 3 outputs a first control signal when the electronic device is connected to an external charger, the power level of the battery cell 1 is greater than a first preset power threshold, and the impact factor is greater than or equal to the preset impact factor threshold, and controls the power regulation component 2 to reduce the power level of the battery cell 1 based on the first control signal. The method has high intelligence, a simple solution, and is easy to implement.

[0188] In some embodiments, the method further comprises:

[0189] detecting the power level of the battery cell 1 during a power reduction process;

[0190] In response to the power of the battery cell 1 being less than a second preset power threshold during the power reduction process, the power regulating component 2 is controlled by the power meter 3 to stop reducing the power of the battery cell 1; wherein the second preset power threshold is less than the first preset power threshold.

[0191] In an embodiment of the present disclosure, the charge of the battery cell 1 during the charge reduction process is detected, wherein the charge of the battery cell 1 during the charge reduction process can be detected by the power meter 3. In response to the charge of the battery cell 1 during the charge reduction process being less than the second preset charge threshold, the power meter 3 controls the charge regulation component 2 to stop reducing the charge of the battery cell 1; the second preset charge threshold is the charge that will not affect the life of the battery cell 1. The second preset charge threshold is a set value, which can be an experimental value or a manually set value. It should be noted that the second preset charge threshold is related to the temperature range of the battery cell 1, wherein the temperature represents the temperature of the battery cell 1 before the charge is reduced as detected by the power meter 3. Different temperature ranges correspond to different second preset charge thresholds. For example, when the temperature range of the battery cell 1 is greater than or equal to 60°, the second preset charge threshold is 89%; when the temperature range of the battery cell 1 is [48°, 60°], the second preset charge threshold is 94%, wherein the second preset charge threshold is less than the first preset charge threshold.

[0192] In an embodiment of the present disclosure, in response to the power of the battery cell 1 being less than the second preset power threshold during the power reduction process, the power regulating component 2 is controlled by the power meter 3 to stop reducing the power of the battery cell 1, including: in response to the power of the battery cell 1 being less than the second preset power threshold during the power reduction process, the power meter 3 is controlled to output a second control signal; based on the second control signal, the power regulating component 2 is controlled to stop reducing the power of the battery cell. As mentioned above, the second control signal includes a level signal. Specifically, the second control signal can be a high-level signal or a low-level signal. In this regard, the embodiment of the present disclosure does not impose any limitation.

[0193] In the embodiment of the present disclosure, the power of the battery cell 1 is detected during the power reduction process, and in response to the detected power being less than a second preset power threshold, the power regulating component 2 is controlled by the power meter 3 to stop reducing the power of the battery cell 1. This can stop reducing the power of the battery cell 1 when the battery cell 1 is no longer in a high power state that can affect the life of the battery cell 1, so as to save the power of the battery cell 1. The method of the embodiment of the present disclosure is highly intelligent.

[0194] In some embodiments, the method further comprises:

[0195] detecting the current of the battery cell 1 during a process in which the power level of the battery cell 1 decreases;

[0196] The detecting the power level of the battery cell 1 during the power reduction process includes:

[0197] In response to the current of the battery cell 1 being within a second preset current threshold range during the process of power reduction, the power of the battery cell 1 during the process of power reduction is detected.

[0198] In an embodiment of the present disclosure, the current of the battery cell 1 during the process of power reduction is detected. For example, the current of the battery cell 1 during the process of power reduction can be detected by a current sampling component, wherein the current sampling component includes a current sampling chip, a current detection resistor and other components that can detect the current of the battery cell 1.

[0199] In an embodiment of the present disclosure, in response to the current of the battery cell 1 during the process of power reduction being within a second preset current threshold range, the power of the battery cell 1 during the process of power reduction is detected, wherein the second preset current threshold range is the current range of the battery cell 1 when the power of the battery cell 1 is reduced by the power regulation component 2. The second preset current threshold range is a set threshold range, which can be measured through experiments, or can be a factory setting of the electronic device, or can be set manually. In this regard, the embodiment of the present disclosure does not impose any restrictions. For example, if the second preset current threshold range is [-30mA, 1mA], it should be noted that at this time, since the power meter 3 has controlled the power regulation component 2 to reduce the power of the battery cell 1, the upper limit current of the second preset current threshold range should be less than the upper limit current of the first preset current threshold range, and the lower limit current of the second preset current threshold range should be less than the lower limit current of the first preset current threshold range.

[0200] In the embodiment of the present disclosure, when it is determined that the current of the battery cell 1 is within the second preset current threshold range, the method of determining the power of the battery cell 1 during the power reduction process can first determine based on the current whether the battery cell 1 only reduces its own power through the power regulation component 2 at this time, and then determine the power when it is determined that the battery cell 1 only reduces its own power through the power regulation component 2. The power is controlled according to the power, that is, the embodiment of the present disclosure is highly intelligent.

[0201] In some embodiments, the method further comprises:

[0202] In response to the current of the battery cell 1 being less than the lower limit current in the second preset current threshold range during the process of power reduction being longer than or equal to the second preset time threshold, controlling the power regulation component 2 to stop reducing the power of the battery cell 1 through the power meter 3;

[0203] In response to the current of the battery cell 1 being greater than the upper limit current in the second preset current threshold range for a duration greater than or equal to the second preset duration threshold during the power reduction process, the power regulation component 2 is controlled by the power meter 3 to stop reducing the power of the battery cell 1.

[0204] In the embodiment of the present disclosure, in response to the current of the battery cell 1 being less than the lower limit current in the second preset current threshold range during the power reduction process, or being greater than the upper limit current in the second preset current threshold range for a duration greater than or equal to the second preset time threshold, the power regulating component 2 is controlled by the power meter 3 to stop reducing the power of the battery cell 1. As mentioned above, the second preset current threshold range is a set threshold range, which can be measured through experiments, or can be a factory setting of the electronic device, or can be set manually. For example, the second preset current threshold range is set to [-30mA, 1mA]. At this time, the lower limit current in the second preset current threshold range is -30mA, and the upper limit current in the second preset current threshold range is 1mA. A. The second preset time threshold is a set value, which can be an experimental value or an artificial setting. For example, the second preset time threshold is set to 30 seconds. It should be noted that the second preset current threshold range is the current threshold range when the battery cell 1 is discharged only through the power regulation component 2. When the current is less than the lower limit current in the second preset current threshold range for a time greater than or equal to the second preset time threshold, it means that the battery cell 1 is still supplying power to other loads at this time, and there is no need to reduce the power of the battery cell 1 through the power regulation component 2. When the current is greater than the upper limit current in the second preset current threshold range for a time greater than or equal to the second preset time threshold, it means that the battery cell 1 may be damaged and the power of the battery cell 1 cannot be reduced through the power regulation component 2.

[0205] In the embodiment of the present disclosure, in response to the current of the battery cell 1 being less than the lower limit current in the second preset current threshold range during the power reduction process, or being greater than the upper limit current in the second preset current threshold range for a duration greater than or equal to the second preset duration threshold, the power meter 3 is used to control the power regulation component 2 to stop reducing the power of the battery cell 1. This method can determine the state of the battery cell 1 based on the current, and stop reducing the power of the battery cell 1 through the power regulation component 2 when the battery cell 1 is supplying power to other loads or the battery cell 1 is damaged. This can store the electrical energy of the battery cell 1, better protect the battery cell 1, and thus extend the life of the battery cell 1.
