At the same time, the steps or actions in the method description can also be sequentially adjusted or adjusted in a manner that is obvious to those skilled in the art. Therefore, the order in the specification and the drawings is only for the purpose of clear description of an embodiment, and does not mean that it is the necessary order, unless otherwise stated that a certain order must be followed.

[0025] The serial numbers of components in this paper, such as "first", "second", etc., are only used to distinguish the described objects, and have no order or technical meaning. Unless otherwise specified, "connection" and "coupling" in this application include direct and indirect connection (coupling).

[0026] The technical solutions of the present application will be described in detail below in combination with embodiments.

[0027] The present application provides a battery. Please refer to Figure 1The battery includes a rechargeable power supply 100, which is used to supply power to the electronic device, comprising:

[0028] The pulse signal generating unit 200 is used to generate a pulse signal of a preset frequency and send the pulse signal to the electronic device; wherein the pulse signal generating unit 200 is electrically connected with the rechargeable power supply 100.

[0029] It should be noted that the specific setting of the rechargeable power supply belongs to the prior art in the field. The battery can also include a battery chip. The CPU of the electronic device determines whether the battery is an original battery by detecting whether the pulse signal of the preset frequency is received. The specific range of the preset frequency can be determined by the person skilled in the art according to the actual scene requirements.

[0030] In some embodiments, the pulse signal generating unit can be provided on the above-mentioned battery chip.

[0031] In some embodiments, only the battery that can generate a pulse signal of a preset frequency and send the pulse signal to the electronic device can be regarded as the original battery mentioned in the present application.

[0032] In some embodiments, if it is determined that the battery is not an original battery, the battery stops supplying power to the electronic device or limits the use of the electronic device (such as not being able to normally connect to the network after starting, the electronic device entering shutdown or flight mode) and / or issuing an alarm.

[0033] In some embodiments, the pulse signal generating unit is an MCU (micro control unit). Wherein the positive electrode pin of the power supply of the MCU is electrically connected with the positive electrode of the rechargeable power supply, and the output pin of the MCU outputs the pulse signal.

[0034] The person skilled in the art can set the MCU according to the actual scene requirements to adjust the frequency of the pulse signal. For example, the MCU can output the pulse signal according to the following rule: first, a high level for a first time (such as 2ms), then a low level for a second time (such as 3ms), then a high level for a third time (such as 2ms), and finally a low level for a fourth time (such as 3ms), and so on. When the CPU of the electronic device detects the pulse signal of the above-mentioned preset frequency, it is determined that the battery is an original battery.

[0035] In some embodiments, please refer to Figure 2 The pulse signal generating unit includes an active crystal oscillator Z1 and a first capacitor C1; wherein the voltage input pin VCC of the active crystal oscillator Z1 and one end of the first capacitor C1 are electrically connected with the positive electrode VBAT of the rechargeable power supply, the other end of the first capacitor C1 is grounded, and the first ground pin and the second ground pin of the active crystal oscillator Z1 are both grounded. The frequency output pin OUT of the active crystal oscillator Z1 can output the above-mentioned pulse signal.

[0036] It should be noted that the active crystal oscillator described above belongs to the prior art in the field.

[0037] In some embodiments, referring to Figure 2 , the pulse signal generation part further comprises a second capacitor C4 and a resistor R1; one end of the resistor R1 and one end of the second capacitor C4 are both electrically connected to the frequency output pin OUT of the active crystal oscillator Z1, the other end of the second capacitor C4 is grounded, and the other end of the resistor R1 outputs a pulse signal such as Figure 2 CLK. The resistor R1 and the second capacitor C4 can form an RC circuit. The RC circuit is used to adjust the waveform of the sine wave signal output by the active crystal oscillator Z1.

[0038] It can be understood that the positive electrode of the battery can supply power to the active crystal oscillator Z1. When the active crystal oscillator Z1 is working normally, the frequency output pin OUT of the active crystal oscillator Z1 generates a sine wave signal with an amplitude and a frequency corresponding to the model of the active crystal oscillator Z1. Then, the waveform of the sine wave signal output by the active crystal oscillator Z1 is appropriately adjusted through the second capacitor C4 and the resistor R1 to obtain a pulse signal with a preset frequency. Finally, the CPU of the electronic device detects whether the pulse signal exists through the rising edge, or detects whether the pulse signal with the preset frequency is received, to determine whether the battery is an original battery. That is, when the CPU of the electronic device detects that the voltage amplitude, frequency and / or interval time of the received pulse signal meet the preset range, the electronic device can normally start the boot program; otherwise, the power supply of the battery to the electronic device is stopped, or the use of the electronic device is limited, such as the electronic device cannot normally connect to the network after booting, the electronic device enters the shutdown or flight mode, and / or an alarm is issued.

[0039] It should be noted that the specific process of "appropriately adjusting the waveform of the sine wave signal output by the active crystal oscillator Z1 through the second capacitor C4 and the resistor R1 to obtain a pulse signal with a preset frequency" belongs to the conventional operation in the field, and therefore the process will not be described here.

[0040] In some embodiments, the battery further comprises a signal sending element; wherein the pulse signal generation part sends the pulse signal to the CPU of the electronic device through the signal sending element.

[0041] In some embodiments, the signal sending element is a signal sending pin, which is electrically connected to the output end of the pulse signal generation part. The electronic device comprises a signal receiving pin, which is used to receive the pulse signal and forward the pulse signal to the CPU of the electronic device.

[0042] It can be understood that the signal sending element can also be other elements capable of forwarding the pulse signal.

[0043] As can be seen, in some embodiments, the battery provided by the present application comprises a pulse signal generating unit for generating a pulse signal of a preset frequency and sending the pulse signal to the electronic device; and the CPU of the electronic device can determine whether the battery connected to the electronic device is an original battery by detecting whether the pulse signal of the preset frequency is received. That is, only the battery capable of generating a pulse signal of a preset frequency and sending the pulse signal to the electronic device can be regarded as the original battery mentioned in the present application.

[0044] The above is some description of a battery. Please refer to Figure 3 The present application also discloses an electronic device A which can be powered by a battery B, and the battery B can send a customized signal to the electronic device A, wherein the customized signal is a pulse signal I of a preset frequency. The electronic device A comprises:

[0045] a detection unit 100 for detecting whether the amplitude and / or frequency of the pulse signal I is within a preset range to determine whether the battery B is an original battery.

[0046] It should be noted that if the detection unit determines that the battery is not an original battery, the battery stops supplying power to the electronic device, or the use of the electronic device is limited, such as the electronic device cannot normally connect to the network after starting up, the electronic device enters shutdown or flight mode, and / or an alarm is issued. Those skilled in the art can determine the preset range according to the actual scene requirements.

[0047] It should be noted that the present application does not improve the control logic of the electronic device.

[0048] In some embodiments, the electronic device can be a mobile terminal such as a mobile phone, a tablet computer, a smart watch, etc.

[0049] In some embodiments, the electronic device can also be an electronic product other than a mobile terminal.

[0050] Since the CPU can detect high and low levels, in some embodiments, the detection unit is the CPU. That is, when the CPU of the electronic device detects that the voltage amplitude, frequency and / or interval time of the received pulse signal meet the preset range, the electronic device can normally start the startup program; otherwise, the battery stops supplying power to the electronic device, or the use of the electronic device is limited, such as the electronic device cannot normally connect to the network after starting up, the electronic device enters shutdown or flight mode, and / or an alarm is issued.

[0051] In some embodiments, the electronic device further comprises a signal receiving pin for receiving the pulse signal and forwarding the pulse signal to the CPU.

[0052] In some embodiments, the battery comprises: a chargeable power supply for supplying power to the electronic device; and a pulse signal generator for generating a pulse signal at a preset frequency and sending the pulse signal to the electronic device; wherein the pulse signal generator is electrically connected to the chargeable power supply.

[0053] It should be noted that the battery has been described above, and thus will not be described again here.

[0054] It can be seen that, in some embodiments, the electronic device of the present application can determine whether the battery is an original battery by detecting whether the amplitude and / or frequency of the pulse signal sent by the battery to the electronic device is within a preset range. If the detection unit determines that the battery is not an original battery, the battery stops supplying power to the electronic device, or the use of the electronic device is limited, such as being unable to normally connect to a network after booting up, the electronic device entering a shutdown or flight mode, and / or an alarm being issued. Those skilled in the art can determine the preset range according to actual scene requirements.
