[0027] The following is in conjunction with the appendix Figures 1 to 10 The power supply circuit and power supply control method provided in this application will be described in detail through specific embodiments and application scenarios.

[0028] In some embodiments of this application, a power supply circuit is provided. Figure 1 A circuit diagram of one of the power supply circuits provided in some embodiments of this application is shown. For example... Figure 1 As shown, the power supply circuit 100 includes at least two battery components 110 and an intermediate logic module 120.

[0029] In this embodiment of the application, the power supply circuit 100 is disposed in a mobile electronic device, specifically in a foldable screen electronic device, and at least two battery components 110 in the power supply circuit 100 are respectively disposed in two folded bodies of the foldable screen device.

[0030] Each battery assembly 110 includes a battery 112 and a metering module 114. The metering module 114 is used to collect the battery signal of the battery 112. An intermediate logic module 120 is electrically connected to at least two battery assemblies 110. The intermediate logic module 120 is used to generate a corresponding logic signal from the battery signal of one of the at least two battery assemblies 110 and send the logic signal to the other battery assemblies 110 in the at least two battery assemblies 110, so that the at least two battery assemblies 110 can control the battery 112 to supply power or stop supplying power according to the logic signal.

[0031] In this embodiment, each battery module 110 is a separate power supply unit, including a battery 112 and a metering module 114. The metering module 114 can collect the battery signal of the battery 112. Each metering module 114 in each battery module 110 is electrically connected to an intermediate logic module 120, and the metering module 114 can transmit the collected battery signal to the intermediate logic module 120. After receiving the battery signal, the intermediate logic module 120 can generate a logic signal based on the battery signal and transmit the logic signal to other metering modules. The intermediate logic module 120 can receive the battery signal transmitted by each metering module 114, generate a logic signal corresponding to each metering module 114 based on the battery signal, and forward the logic signal to other metering modules 114, enabling each metering module 114 to select and control the corresponding battery 112 to supply power or stop supplying power according to the received logic signal.

[0032] In this embodiment of the application, the intermediate logic module 120 is electrically connected to at least two metering modules 114. The intermediate logic module 120 can receive battery signals from the metering modules 114, convert the battery signals into logic signals according to preset logic rules, and transmit the logic signals to other metering modules 114, so that the other metering modules 114 can control the operating state of the corresponding battery 112 based on the logic signals.

[0033] In this embodiment of the application, the metering module 114 can collect battery signals, which include the voltage value output by the battery 112 during operation and parameters such as the number of cycles of the battery 112.

[0034] For example, the metering module 114 includes a VID (Voltage Identification) pin and a SWI (Software Interrupt) pin. The VID pin is used to receive logic signals transmitted by the intermediate logic unit, and the SWI pin is used to output battery signals to the intermediate logic unit.

[0035] The following explanation uses two battery components 110 as an example, namely a first battery component 110 and a second battery component 110. The first battery component 110 includes a first battery 112 and a first metering module 114, and the second battery component 110 includes a second battery 112 and a second metering module 114.

[0036] The first metering module 114 can collect the first battery signal of the first battery 112 and transmit it to the intermediate logic module 120. The intermediate logic module 120 generates a corresponding second logic signal and transmits it to the second metering module 114. The second metering module 114 can collect the second battery signal of the second battery 112 and transmit it to the intermediate logic module 120. The intermediate logic module 120 generates a corresponding first logic signal and transmits it to the first metering module 114. The first metering module 114 can control whether the first battery 112 is powered by the received first logic signal and the first battery signal based on the matching relationship between them. The second metering module 114 can control whether the second battery 112 is powered by the received second logic signal and the second battery signal based on the matching relationship between them.

[0037] Figure 2 A second circuit diagram of a power supply circuit provided in some embodiments of this application is shown, such as... Figure 2 As shown, there are two battery modules, battery module A and battery module B. Battery module A includes battery A and metering module A, and battery module B includes battery B and metering module B. Metering module A collects a first battery signal from battery A and transmits it to an intermediate logic module. The intermediate logic module generates a first logic signal and forwards it to metering module B. Metering module B collects a second battery signal from battery B and transmits it to the intermediate logic module. The intermediate logic module generates a second logic signal and forwards it to metering module A. In summary, metering module A receives the second logic signal and controls battery A to supply power or stop supplying power accordingly. Metering module B receives the first logic signal and controls battery B to supply power or stop supplying power accordingly.

[0038] In this embodiment, an intermediate logic module 120 is provided between at least two battery components 110 in the power supply circuit 100. The intermediate logic module 120 can generate a logic signal based on the battery signal collected by the metering module 114 in one of the battery components 110, and send the generated logic signal to the metering modules 114 in the other battery components 110. This enables the metering module 114 in each battery component 110 to control the power supply state of the battery 112 based on the received logic signal, realizing mutual communication and mutual detection between at least two battery components 110. This eliminates the need for the CPU inside the electronic device to detect each battery component 110 individually. When the CPU is running under high load or malfunctioning, at least two battery components 110 can perform consistency detection, improving the stability and safety of the power supply circuit 100.

[0039] Figure 3The third example shows a circuit diagram of a power supply circuit provided in some embodiments of this application, such as... Figure 3 As shown, in some embodiments of this application, the logic signal includes a waveform signal, and the intermediate logic module 120 includes:

[0040] The waveform generation unit 122 is electrically connected to the metering module in at least two battery components 110, and is used to generate a waveform signal based on the numerical relationship between the voltage value in the battery signal and a first voltage range. The waveform signal corresponds to a target voltage range, which is the first voltage range in which the voltage value in the battery signal is located.

[0041] In this embodiment, the intermediate logic module 120 can be selected as a waveform generation unit 122, which can generate a corresponding waveform signal based on the voltage value in the battery signal. After receiving the battery signal, the intermediate logic module 120 can determine the corresponding waveform signal based on the first voltage range in which the voltage value in the received battery signal is located.

[0042] Specifically, there are multiple first voltage ranges, each corresponding to a different waveform signal. After receiving the battery signal, the voltage value in the battery signal is acquired, and the target voltage range within the multiple first voltage ranges is located. The waveform signal corresponding to the target voltage range is then used as the waveform signal corresponding to the voltage value in the battery signal.

[0043] Table 1 shows the correspondence between waveform signals and first voltage ranges provided in some embodiments of this application. As shown in Table 1, the voltage value in the battery signal is V. When V is within [V1, V2], waveform 1 is used as the waveform signal. When V is within (V2, V3], waveform 2 is used as the waveform signal. When V is within [Vn, Vn+1], waveform 3 is used as the waveform signal.

[0044] Table 1

[0045]

[0046] For example, there are two battery components 110, namely a first battery component 110 and a second battery component 110. When the voltage value VC1 in the first battery signal output by the first battery component 110 and the voltage value VC2 in the second battery signal output by the second battery component 110 are both within the voltage range [V1, V2], the waveform signals generated by the waveform generation unit 122 are both waveform 1. It is then determined that the first battery component 110 and the second battery component 110 are successfully paired and have good consistency. The first battery component 110 and the second battery component 110 are supplying power normally.

[0047] For example, there are two battery components 110, namely a first battery component 110 and a second battery component 110. When the voltage value VC1 in the first battery signal output by the first battery component 110 is within the voltage range (V2, V3], the corresponding waveform signal is waveform 2. When the voltage value VC1 in the second battery signal output by the second battery component 110 is within the voltage range [V1, V2], the waveform signals generated by the waveform generation unit 122 are both waveform 1. It can be seen that the waveforms of the two waveform signals are inconsistent, so the two battery components 110 cannot be properly paired, and therefore the first battery component 110 and the second battery component 110 stop supplying power.

[0048] In this embodiment, the waveform generation unit 122 can generate different waveform signals according to preset programming logic when the voltage of the battery signal is in a different first voltage range. After the metering module 114 receives the waveform signal, it can determine the voltage value in the battery signal corresponding to the received waveform signal, and then control the battery 112 to supply power or stop supplying power based on the waveform signal.

[0049] The following explanation uses two battery components 110 as an example, namely a first battery component 110 and a second battery component 110. The first battery component 110 includes a first battery 112 and a first metering module 114, and the second battery component 110 includes a second battery 112 and a second metering module 114.

[0050] The first metering module 114 can acquire the first battery signal of the first battery 112 and transmit it to the intermediate logic module 120. The intermediate logic module 120 generates a corresponding second logic signal as a second waveform signal and transmits it to the second metering module 114. The second metering module 114 can acquire the second battery signal of the second battery 112 and transmit it to the intermediate logic module 120. The intermediate logic module 120 generates a corresponding first logic signal as a first waveform signal and transmits it to the first metering module 114. The first metering module 114 can control whether the first battery 112 is powered by the first preset waveform by matching the waveform of the received first waveform signal with a first preset waveform determined based on the first battery signal. The second metering module 114 can control whether the second battery 112 is powered by the second preset waveform by matching the waveform of the received second waveform signal with a second preset waveform determined based on the second battery signal.

[0051] In the embodiments of this application, by setting the intermediate logic module 120 as a waveform generation unit 122, the waveform generation unit 122 can generate waveform signals of different waveforms according to the different received battery signals, and transmit the waveform signals to other metering modules 114, so that the metering modules 114 in at least two battery components 110 can select and control whether the corresponding battery 112 is powered through the waveform signals, thereby realizing the interoperability detection of the consistency of the batteries 112 in the two battery components 110, and improving the operational stability and safety.

[0052] Figure 4 The fourth example shows a circuit diagram of a power supply circuit provided in some embodiments of this application, such as... Figure 4 As shown, in some embodiments of this application, the logic signals include level signals, and the intermediate logic module 120 includes a power management unit 124.

[0053] The power management unit 124 is electrically connected to the metering module in at least two battery packs 110 and is used to generate a level signal based on the numerical relationship between the voltage value in the battery signal and a second voltage range. The level signal corresponds to a target voltage range, which is the second voltage range in which the voltage value in the battery signal is located.

[0054] In this embodiment, the intermediate logic module 120 can be selected as a power management unit 124, which can generate a corresponding level signal based on the battery signal. After receiving the battery signal, the intermediate logic module 120 can determine the corresponding level signal based on the second voltage range of the voltage value in the received battery signal.

[0055] Specifically, there are multiple second voltage ranges, each corresponding to a different voltage level signal. After receiving the battery signal, the voltage value in the battery signal is acquired, and the target voltage range within the multiple second voltage ranges is located. The voltage level signal corresponding to the target voltage range is then used as the voltage level signal corresponding to the voltage value in the battery signal.

[0056] In this embodiment, the power management unit 124 can generate different level signals according to preset programming logic when the voltage value in the battery signal is in a different second voltage range. After the metering module 114 receives the level signal, it can determine the voltage value in the battery signal corresponding to the received level signal, and then control the battery 112 to supply power or stop supplying power based on the level signal.

[0057] The following explanation uses two battery components 110 as an example, namely a first battery component 110 and a second battery component 110. The first battery component 110 includes a first battery 112 and a first metering module 114, and the second battery component 110 includes a second battery 112 and a second metering module 114.

[0058] The first metering module 114 can collect the first battery signal of the first battery 112 and transmit the first battery signal to the intermediate logic module 120. The intermediate logic module 120 generates a corresponding second logic signal as a second level signal and transmits the second level signal to the second metering module 114. The second metering module 114 can collect the second battery signal of the second battery 112 and transmit the second battery signal to the intermediate logic module 120. The intermediate logic module 120 generates a corresponding first logic signal as a first level signal and transmits the first level signal to the first metering module 114. When the level value of the first level signal matches the level value of the second level signal, the first battery assembly 110 and the battery 112 in the second battery assembly 110 are controlled to supply power normally. When the level value of the first level signal does not match the level value of the second level signal, the first battery assembly 110 and the battery 112 in the second battery assembly 110 are controlled to stop supplying power.

[0059] In the embodiments of this application, by setting the intermediate logic module 120 as a power management unit 124, the power management unit 124 can generate different waveform level signals according to the different received battery signals, and transmit the level signals to other metering modules 114. This enables the metering modules 114 in at least two battery packs 110 to select and control whether the corresponding battery 112 is powered through the level signals, thereby realizing the interoperability detection of the consistency of the batteries 112 in the two battery packs 110 and improving the operational stability and safety.

[0060] Figure 5 The fifth example shows a circuit diagram of a power supply circuit 100 provided in some embodiments of this application, such as... Figure 5 As shown, in some embodiments of this application, the logic signal includes a characteristic peak signal, and the intermediate logic module 120 includes a feature recognition unit 126.

[0061] The feature recognition unit 126 is electrically connected to the metering module in at least two battery components 110 and is used to extract the feature peak signal corresponding to the number of cycles in the battery signal.

[0062] In this embodiment, the intermediate logic module 120 can be selected as a feature recognition unit 126. The feature peak recognition unit can extract features based on multiple voltage boost signals sent by the metering module 114, thereby generating corresponding feature peak signals.

[0063] In this embodiment, the characteristic peak signal is the signal of the characteristic peak value of the potential output by the battery 112. Before the battery component 110 leaves the factory, a characteristic peak model corresponding to different cycle numbers is established for the battery component 110. As the battery component 110 ages, the shift of the characteristic peak becomes greater. Figure 6 The following are characteristic peak curves provided by some embodiments of this application, such as... Figure 6 As shown, when the number of cycles of the battery module 110 is n, the characteristic peak is shown as curve 1, and when the number of cycles of the battery module 110 is n+m, the characteristic peak is shown as curve 2.

[0064] Specifically, after receiving the battery signal transmitted by the metering module 114, the feature recognition unit 126 can identify the number of cycles in the battery signal and determine the corresponding characteristic peak signal through the number of cycles.

[0065] The following explanation uses two battery components 110 as an example, namely a first battery component 110 and a second battery component 110. The first battery component 110 includes a first battery 112 and a first metering module 114, and the second battery component 110 includes a second battery 112 and a second metering module 114.

[0066] The first metering module 114 in the first battery assembly 110 calls the characteristic peak signal from the modeling based on the cycle count of battery 112 and sends it to the second metering module 114 in the second battery assembly 110. Similarly, the second metering module 114 in the second battery assembly 110 calls the characteristic peak signal from the modeling based on the cycle count of battery 112 and sends it to the first metering module 114 in the first battery assembly 110. The first and second metering modules 114 can determine whether the two characteristic peak signals match. If the two characteristic peak signals match, it is determined that the cycle counts of the first battery 112 and the second battery 112 in the first battery assembly 110 are consistent, meaning that the aging levels of the first battery 112 and the second battery 112 are consistent, and the first and second batteries 112 are controlled to supply power normally. Otherwise, the first and second batteries 112 are controlled to stop supplying power.

[0067] In this embodiment, by setting the intermediate logic module 120 as the feature recognition unit 126, the intermediate logic module 120 can extract the cycle number of at least two battery components 110, generate feature peak signals corresponding to at least two battery components 110, and transmit the feature peak signals to other battery components 110. This allows the metering module 114 in at least two battery components 110 to select and control whether the corresponding battery 112 is powered through the feature peak signals, thereby realizing the interoperability detection of the consistency of the batteries 112 in the two battery components 110 and improving the operational stability and safety.

[0068] like Figure 1 As shown, in some embodiments of this application, the battery assembly 110 includes a switching element 116 and a current detection unit 118.

[0069] The control terminal of the switch 116 is connected to the metering module 114, and the switch 116 is electrically connected to the battery 112. The switch 116 is used to control the battery 112 to supply power or stop supplying power. The sampling terminal of the current detection unit 118 is connected to the battery 112 and is used to collect the current value of the battery 112.

[0070] In this embodiment of the application, each battery assembly 110 is also provided with a switch 116 and a current detection unit 118. The current detection unit 118 can detect the current output by the battery 112 in the battery assembly 110, and the switch 116 can control and switch whether the battery 112 in the battery assembly 110 is powered.

[0071] In this embodiment, the control terminal of the switch 116 is connected to the metering module 114. After receiving a logic signal, the metering module 114 can control the on / off state of the switch 116 based on the logic signal. Since the switch 116 is located at the power supply terminal of the battery 112, when the switch 116 is open, the battery 112 stops supplying power to the outside, and when the switch 116 is closed, the battery 112 can supply power to the outside.

[0072] In this embodiment of the application, the output terminal of the current detection unit 118 is connected to the metering module 114. The metering module 114 can collect the current value output by the battery 112 through the current detection unit 118. The current detection power supply, together with the metering module 114, can realize the overcurrent detection of the battery assembly 110.

[0073] For example, the battery assembly 110 may also include peripheral devices such as a temperature detection unit and a battery 112 protection IC (integrated circuit), which can realize protection mechanisms such as over-discharge, overcharge, short circuit, overcurrent, and over-temperature of the battery 112, as well as waveform detection function of the VID pin.

[0074] In this embodiment, by providing a switch 116 in the battery assembly 110, the battery assembly 110 can independently control whether it supplies power to the outside. When the battery 112 in the battery assembly 110 malfunctions, it can promptly stop the battery 112 from supplying power to the outside, thereby improving the stability of the operation of the battery assembly 110.

[0075] In some embodiments of this application, a power supply control method is provided, which is applied to a first battery component in a power supply circuit provided in some embodiments of this application, wherein the first battery component is any one of at least two battery components. Figure 7 A flowchart illustrating a power supply control method provided in some embodiments of this application is shown. For example... Figure 7 As shown, the power supply control method includes:

[0076] Step 702: Obtain the first battery signal of the battery in the first battery assembly;

[0077] In this embodiment of the application, the first battery signal includes information such as the number of cycles of the battery in the first battery assembly and the voltage value output by the battery in the first battery assembly.

[0078] Step 704: Receive the first logic signal transmitted by the intermediate logic module. The first logic signal is a logic signal generated based on the second battery signal.

[0079] The second battery signal is the battery signal transmitted from the second battery component to the intermediate logic module, and the second battery component is another battery component among at least two battery components.

[0080] In this embodiment, the first logic signal is a logic signal generated by the intermediate logic module receiving the second battery signal transmitted by the second battery component.

[0081] Step 706: Based on the matching relationship between the first logic signal and the first battery signal, control the battery in the first battery assembly to supply power or stop supplying power.

[0082] In this embodiment, the first battery assembly includes a first metering module, and the second battery assembly includes a second metering module. The first metering module collects a first battery signal from the battery in the first battery assembly and transmits it to an intermediate logic module. The intermediate logic module generates a corresponding second logic signal and transmits it to the second metering module. The second metering module collects a second battery signal from the battery in the second battery assembly and transmits it to the intermediate logic module. The intermediate logic module generates a corresponding first logic signal and transmits it to the first metering module. The first metering module controls whether the first battery is powered by the received first logic signal and the first battery signal based on their matching relationship. The second metering module controls whether the second battery is powered by the received second logic signal and the second battery signal based on their matching relationship.

[0083] In this embodiment, an intermediate logic module is provided between at least two battery components in the power supply circuit. The intermediate logic module can generate a logic signal based on the battery signal collected by the metering module in one of the battery components, and send the generated logic signal to the metering modules in the remaining battery components. This enables the metering module in each battery component to control the power supply status of the battery based on the received logic signal, realizing mutual communication and mutual detection between at least two battery components. It eliminates the need for the CPU inside the electronic device to detect the battery components individually. When the CPU is running under high load or malfunctions, at least two battery components can perform consistency detection, improving the stability and safety of the power supply circuit.

[0084] In some embodiments of this application, the first logic signal includes a waveform signal; controlling the battery in the first battery assembly to supply power or stop supplying power based on the matching relationship between the first logic signal and the first battery signal includes: determining a preset waveform based on the voltage value in the first battery signal; controlling the battery to supply power when the waveform of the waveform signal matches the preset waveform; and controlling the battery to stop supplying power when the waveform of the waveform signal does not match the preset waveform.

[0085] In this embodiment of the application, the intermediate logic module can be a waveform generation unit, and the waveform signal is the waveform signal generated by the waveform generation unit upon receiving the battery signal.

[0086] In this embodiment, the preset waveform is the waveform of the waveform signal corresponding to the first battery signal. It should be noted that both the intermediate logic module and the metering module in each battery assembly can determine the corresponding waveform signal based on the first voltage range in which the voltage value in the received battery signal falls. Specifically, there are multiple first voltage ranges, each corresponding to a different waveform signal. The first metering module in the first battery assembly can find the target voltage range in which the voltage value in the first battery signal falls among the multiple first voltage ranges, and determine the waveform of the waveform signal corresponding to the target voltage range as the preset waveform.

[0087] In this embodiment, the waveform generation unit can generate different waveform signals based on the voltage values ​​in different battery signals according to preset programming logic. After the metering module receives the waveform signal, it can determine the voltage value in the battery signal corresponding to the received waveform signal, and thus control the battery to supply power or stop supplying power based on the waveform signal.

[0088] For example, a first battery assembly includes a first metering module, and a second battery assembly includes a second metering module. A first logic signal is a first waveform signal, and a second logic signal is a second waveform signal. The first metering module can acquire the first battery signal of the first battery assembly and transmit it to an intermediate logic module. The intermediate logic module generates a corresponding second logic signal as a second waveform signal and transmits it to the second metering module. The second metering module can acquire the second battery signal of the second battery assembly and transmit it to the intermediate logic module. The intermediate logic module generates a corresponding first logic signal as a first waveform signal and transmits it to the first metering module. The first and second metering modules can determine whether to control the batteries in the first and second battery assemblies to supply power based on the matching relationship between the received first and second waveform signals. When the waveforms of the first and second waveform signals match, both batteries in the first and second battery assemblies supply power normally. When the waveforms of the first and second waveform signals do not match, both batteries in the first and second battery assemblies stop supplying power.

[0089] In the embodiments of this application, by setting the intermediate logic module as a waveform generation unit, the waveform generation unit can generate waveform signals of different waveforms according to the different received battery signals, and transmit the waveform signals to other metering modules. This enables the metering modules in at least two battery modules to select and control whether the corresponding battery is powered through the waveform signals, thereby realizing the interoperability detection of battery consistency in the two battery modules and improving operational stability and safety.

[0090] In some embodiments of this application, the first logic signal includes a level signal; controlling the battery in the first battery assembly to supply power or stop supplying power based on the matching relationship between the first logic signal and the first battery signal includes: determining a preset level value based on the voltage value in the first battery signal; controlling the battery to supply power when the level value of the level signal matches the preset level value; and controlling the battery to stop supplying power when the level value of the level signal does not match the preset level value.

[0091] In this embodiment, the intermediate logic module can be a power management unit, and the level signal is a waveform signal generated by the power management unit upon receiving the battery signal.

[0092] In this embodiment, the preset level value is the level value of the level signal corresponding to the first battery signal. It should be noted that both the intermediate logic module and the metering module in each battery assembly can determine the corresponding level signal based on the second voltage range in which the voltage value in the received battery signal falls. Specifically, there are multiple second voltage ranges, each corresponding to a different level signal. The first metering module in the first battery assembly can find the target voltage range in which the voltage value in the first battery signal falls among the multiple first voltage ranges, and use the level value of the level signal corresponding to the target voltage range as the preset level value.

[0093] In this embodiment, the power management unit can generate different voltage levels based on different battery signals according to preset programming logic. After the metering module receives the waveform signal, it can determine the voltage value in the battery signal corresponding to the received voltage level signal, and thus control the battery to supply power or stop supplying power based on the voltage level signal.

[0094] For example, a first metering module is provided in the first battery assembly, and a second metering module is provided in the second battery assembly. The first metering module can collect the first battery signal of the first battery assembly and transmit the first battery signal to an intermediate logic module. The intermediate logic module generates a corresponding second logic signal as a second level signal and transmits the second level signal to the second metering module. The second metering module can collect the second battery signal of the second battery assembly and transmit the second battery signal to the intermediate logic module. The intermediate logic module generates a corresponding first logic signal as a first level signal and transmits the first level signal to the first metering module. When the level value of the first level signal matches the level value of the second level signal, the batteries in the first and second battery assemblies are controlled to supply power normally. When the level values ​​of the first and second level signals do not match, the batteries in the first and second battery assemblies are controlled to stop supplying power.

[0095] In the embodiments of this application, by setting the intermediate logic module as a power management unit, the power management unit can generate different waveform level signals according to the different battery signals received, and transmit the level signals to other metering modules. This enables the metering modules in at least two battery packs to select and control whether the corresponding battery is powered through the level signals, thereby realizing the interoperability detection of battery consistency in the two battery packs and improving operational stability and safety.

[0096] In some embodiments of this application, the first logic signal includes a characteristic peak signal; based on the matching relationship between the first logic signal and the first battery signal, controlling the battery in the first battery assembly to supply power or stop supplying power includes: determining a preset characteristic peak signal according to the number of cycles in the first battery signal; controlling the battery to supply power when the characteristic peak signal matches the preset characteristic peak signal; and controlling the battery to stop supplying power when the characteristic peak signal does not match the preset characteristic peak signal.

[0097] In this embodiment, the intermediate logic module can be a feature recognition unit, and the feature peak signal is a feature peak signal determined by the feature recognition unit based on the number of cycles in the received battery signal.

[0098] In this embodiment, the preset characteristic peak signal is a characteristic peak signal determined based on the number of cycles in the first battery signal. It should be noted that both the intermediate logic module and the metering module in each battery assembly can determine the corresponding characteristic peak signal based on the number of cycles in the battery signal.

[0099] For example, a first battery assembly includes a first metering module, and a second battery assembly includes a second metering module. The first metering module in the first battery assembly sends the characteristic peak signal from the modeling process to the second metering module in the second battery assembly based on the battery cycle count. Conversely, the second metering module in the second battery assembly sends the characteristic peak signal from the modeling process to the first metering module in the first battery assembly based on the battery cycle count. The first and second metering modules can determine whether the two characteristic peak signals match. If the two characteristic peak signals match, it is determined that the cycle counts of the first battery in the first battery assembly and the second battery in the second battery assembly are the same, i.e., the aging levels of the first and second batteries are the same, and the first and second batteries are controlled to supply power normally. Otherwise, the first and second batteries are controlled to stop supplying power.

[0100] In this embodiment, by setting the intermediate logic module as a feature recognition unit, the intermediate logic module can extract the cycle count of at least two battery components and generate feature peak signals corresponding to at least two battery components accordingly. The feature peak signals are then transmitted to other battery components, enabling the metering modules in at least two battery components to select and control whether the corresponding battery is powered through the feature peak signals. This achieves interoperability detection of battery consistency in the two battery components, improving operational stability and safety.

[0101] In some embodiments of this application, after obtaining the first battery signal of the battery in the first battery assembly, the method further includes: transmitting the first battery signal to an intermediate logic module so that the intermediate logic module generates a second logic signal and transmits the second logic signal to the second battery assembly.

[0102] In this embodiment, the metering module in the first battery module sends the first battery signal to the intermediate logic module. The intermediate logic module can generate a second logic signal based on the first battery signal and transmit the second logic signal to the second battery module, ensuring that the second battery module can also receive the corresponding second logic signal from the first battery module. This enables the first battery module and the second battery module to detect consistency in phase, thereby improving the stability of the operation of the first battery module and the second battery module.
