[0024] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0025] Radio Frequency Identification (RFID) is a non-contact automatic identification technology. In an RFID system, generally composed of a reader, an antenna and an electronic tag. The reader converts the current signal into electromagnetic wave signal through the antenna, and communicates with the electronic tag in a wireless manner, including reading or rewriting the information in the electronic tag. Compared with the traditional bar code, RFID technology has the advantages of long reading distance, high speed, non-visual identification, multi-tag reading, etc.

[0026] Nowadays, with the growing global demand for sustainable energy and the increasing pursuit of portability and flexibility, the demand for energy storage devices is showing a significant growth trend. These devices not only effectively store renewable energy-generated electricity, providing reliable power support for outdoor activities, emergency situations, and scenarios requiring portable power in daily life, but also, with the development of smart home technology and the Internet of Things, they provide stable power supply for an increasing number of smart devices, further driving the expansion of the energy storage device market. The progress of energy storage technology not only helps to reduce carbon emissions, but also promotes the modernization of energy systems, enabling people to more flexibly manage and use electricity resources.

[0027] These energy storage products will be in a closed state during transportation, warehousing, and retail, and will not be connected to the Internet for software updates. The existing solution is to open the package in the warehouse, turn on the device, connect to Wi-Fi or Bluetooth for system updates, and then repackage. This method can achieve software updates, but it consumes a lot of manual costs such as unpacking, operation, and repacking. Moreover, the existing solution has some problems and limitations: first, the operation steps are many, and the labor and material costs are high; second, it affects the integrity of the product packaging and requires repackaging, which increases the risk of product damage during unpacking and repacking; third, software updates are time-consuming and labor-intensive, and cannot meet the modern logistics demand for speed and efficiency. Therefore, how to achieve the boot-up and software update of portable energy storage devices without opening the package has become a problem to be solved.

[0028] To achieve the boot-up of electronic devices that are sealed in a package and in a closed state, the embodiments of the present application provide a package-free electronic device boot-up system.

[0029] It should be noted that in the embodiments of the present application, the above-mentioned electronic devices can not only refer to energy storage devices, but also to other devices. For example, the above-mentioned electronic devices can include but are not limited to:

[0030] 1. Communication and computing devices: smartphones, tablets, smartwatches, laptops, wireless earphones;

[0031] 2. Audio devices: Bluetooth earphones, portable speakers, true wireless earphones;

[0032] 3. Entertainment devices: portable game consoles, action cameras, portable projectors;

[0033] 4. Health and fitness devices: health and fitness trackers, smart glasses;

[0034] 5. Auxiliary and navigation devices: GPS navigation devices, smart home controllers;

[0035] 6. Lighting device: portable lighting device;

[0036] 7. Input device: wireless keyboard, wireless mouse;

[0037] 8. Charging and power management device: portable power supply / mobile power supply, energy storage power supply;

[0038] 9. Smart home device: smart remote control;

[0039] 10. Professional and special purpose device: unmanned aerial vehicle, e-book reader, digital camera.

[0040] In the embodiments of the present application, exemplary, Figure 2 A schematic diagram of a start-up system of an electronic device in a Figure 2 The system comprises an RFID reader / writer 10 and an electronic device 20 sealed in a package and in a shutdown state, and the electronic device comprises an RFID chip 21.

[0041] The RFID chip 21 is configured to receive an RF electromagnetic wave signal sent by the RFID reader / writer 10, send an RFID identification code to the RFID reader / writer 10, and receive a start-up instruction sent by the RFID reader / writer 10 based on the RFID identification code.

[0042] The start-up instruction is used to control the electronic device to start up.

[0043] The electronic device can include one of an energy storage power supply, a mobile terminal, a smart terminal, and an unmanned aerial vehicle.

[0044] Figure 2 In the embodiments, the RFID reader / writer 10 first sends an RF electromagnetic wave signal to the RFID chip 21. After the RFID chip 21 receives the RF electromagnetic wave signal sent by the RFID reader / writer 10, the RFID chip 21 sends an RFID identification code to the RFID reader / writer 10. The RFID identification code is used to uniquely identify the electronic device 20. After the RFID reader / writer 10 receives the RFID identification code, it can determine whether the electronic device represented by the RFID identification code is a device to be started up. After determining that the electronic device is a device to be started up, the RFID reader / writer 10 can send a start-up instruction to the RFID chip 21, so that after the RFID chip 21 receives the start-up instruction, the electronic device is controlled to start up.

[0045] When the RFID reader sends an RF electromagnetic wave signal to the RFID chip in one or more electronic devices, the RFID chip sends back an RFID identification code to the RFID reader. The identification code is like an "identity card" for the electronic device, and can be used by the RFID reader to accurately identify the specific electronic device. Through the identification code, the RFID reader can determine whether the electronic device is a device to be started up. If it is determined that the electronic device is a device to be started up, the RFID reader sends a start-up instruction to the RFID chip in the electronic device, thereby controlling the electronic device to start up.

[0046] The above-described unpacking-free electronic device start-up system includes an RFID reader, an electronic device sealed in a package and in a shutdown state, and an RFID chip in the electronic device that can receive an RF electromagnetic wave signal sent by the RFID reader. After receiving the RF electromagnetic wave signal sent by the RFID reader, the RFID chip can send an RFID identification code to the RFID reader, and receive a start-up instruction sent by the RFID reader based on the RFID identification code, the start-up instruction being used to control the electronic device to start up. In this way, the RFID reader outside the electronic device package can control the electronic device sealed in the package and in a shutdown state to start up, and the electronic device can start up without unpacking.

[0047] In the embodiment, in order to make the electronic device start up, an RFID activation circuit is added inside the electronic device, the RFID activation circuit including the RFID chip and an activation control circuit. When not working, the standby power consumption of the RFID activation circuit is zero, and the energy of the battery in the electronic device is not consumed. When the electronic device needs to start up, the RFID reader can non-contact supply energy to the RFID chip within a certain distance range, and then the activation control circuit can start up the electronic device. After the electronic device starts up, a series of operations can be performed, such as state monitoring, remote control, fault diagnosis, and firmware upgrade. The RFID activation circuit uses the RFID chip, and even if the electronic device is wrapped with paper, wood, plastic, and other non-metallic and non-transparent materials, the RFID activation circuit can still perform penetrating communication, thereby triggering the electronic device in the package to start up.

[0048] The RFID activation circuit can be used to trigger the electronic device to start up without opening the package. Since the RFID has mature standard security protocols (such as the ISO / IEC18000-6C protocol), the RFID activation circuit can effectively prevent false triggering.

[0049] For example, the RFID reader can be a handheld device, and the electronic device can be a mobile phone. Figure 3 For example, the RFID reader can be a handheld device, and the electronic device can be a mobile phone. Figure 3Fig. 1 shows a schematic diagram of an unpacking-free electronic device booting system Figure 4 As shown in Fig. 2, the electronic device includes an RFID activation circuit 20a, which includes an activation control module 22 and an RFID chip 21. Figure 4

[0050] In the embodiments of the present application, an example is shown in combination with Figure 4 As shown in Fig. 2, the electronic device includes an RFID activation circuit 20a, which includes an activation control module 22 and an RFID chip 21. Figure 4 Fig. 1 shows a schematic diagram of an unpacking-free electronic device booting system Figure 2 The electronic device 20 further includes a battery 23, an auxiliary power supply 24, and the activation control module 22, which is connected to the battery 23, the auxiliary power supply 24, and the RFID chip 21.

[0051] The RFID chip 21 is configured to output an electrical signal upon receiving a booting instruction; and the activation control module 22 is configured to turn on the battery 23 and the auxiliary power supply 24 based on the electrical signal output by the RFID chip 21, and further activate the auxiliary power supply 24 to control the electronic device 20 to boot up.

[0052] The RFID chip 21 can be a switch-type RFID chip or a power output-type RFID chip.

[0053] The switch-type RFID chip is a radio frequency identification chip with specific functions. This chip mainly plays a role similar to a switch. When interacting with a corresponding RFID reader, it can control the on-off of a certain circuit according to the specific signal received. For example, in some intelligent control systems, the switch-type RFID chip can realize the opening or closing operation of the device power supply by receiving a radio frequency signal. It has the characteristics of fast response and accuracy, and can complete the switching action without direct physical contact.

[0054] An example is shown in Fig. 3, which is a schematic diagram of a switch-type RFID chip. As shown in Fig. 4, the switch-type RFID chip includes an N-channel MOSFET 41, which includes an open drain pin (Open Drain) also known as an open drain circuit, which can output two states of high impedance and low level. Figure 2 Figure 3 As shown in Fig. 4, the switch-type RFID chip includes an N-channel MOSFET 41, which includes an open drain pin (Open Drain) also known as an open drain circuit, which can output two states of high impedance and low level.

[0055] Figure 5 When the input is a high-level signal, the output (i.e., the open drain pin output) can be a low-level signal, and when the input is a low-level signal, the output (i.e., the open drain pin output) presents a high-impedance state, and its level is uncertain. Figure 3 ​​R42 and R43 are both resistors. When the switch-type RFID chip does not receive an activation signal or is in an inactive state, the drain of the N-channel MOSFET is in a high resistance state, equivalent to an open circuit state, and no current passes through; when the switch-type RFID chip receives a specific activation signal, the N-channel MOSFET is turned on, a low resistance path is formed between the drain and the source, and the output end is pulled low to a low level.

[0056] In some embodiments, as shown in FIG. 2, the RFID activation circuit 20a includes the RFID chip 21 and the activation control module 22. Depending on the type of the RFID chip 21, the circuit of the RFID activation circuit 20a is different, which will be described below. Figure 5

[0057] In some embodiments, as shown in FIG. 3, the RFID activation circuit 20a includes the RFID chip 21 and the activation control module 22. Depending on the type of the RFID chip 21, the circuit of the RFID activation circuit 20a is different, which will be described below. Figure 6 Figure 6 As shown in FIG. 4, an exemplary schematic diagram of a start-up system of an electronic device with a pull-out package is shown. Figure 6 Figure 4 . Figure 7 In some embodiments, the RFID chip 21 in the RFID activation circuit 20a can be a switch-type RFID chip 21a, and the activation control module 22 can be a first activation control module 22a. The switch-type RFID chip 21a includes an open-drain pin OD, and the first activation control module 22a is connected to the open-drain pin OD.

[0058] The switch-type RFID chip 21a is configured to output a low-level signal through the open-drain pin OD when receiving a start-up instruction sent by the RFID reader 10.

[0059] The first activation control module 22a is configured to turn on the battery 23 and the auxiliary power supply 24 based on the low-level signal output by the open-drain pin OD, and then activate the auxiliary power supply 24 to control the electronic device 20 to start up.

[0060] In some embodiments, the battery 23 and the auxiliary power supply 24 can be devices in a key start-up circuit of the electronic device, which can be reused in the embodiments of the present application.

[0061] As shown in FIG. 5, an exemplary schematic diagram of a key start-up circuit 60 in an electronic device is shown. Figure 7 As shown in FIG. 6, the key start-up circuit 60 includes a battery 23 (Battery+), a key switch S1, and an auxiliary power supply 24. Figure 7

[0062] ​​​​The aforementioned battery 23 can be formed by connecting multiple batteries in series, and has a voltage of tens of volts. It can be controlled by a microcontroller to a lower voltage such as 5V / 3.3V. Therefore, there is usually an auxiliary power supply 24 (a step-down DC-DC converter) to step down the battery voltage before supplying it to the microcontroller.

[0063] The working principle of the button power-on circuit 60 in the aforementioned electronic device includes: When the electronic device needs to be powered on, the button switch S1 is manually pressed. The auxiliary power supply 24 receives the enable signal after voltage division by a resistor and starts working, converting to a 5V / 3.3V voltage. Then, the microcontroller receives power to run and controls the auxiliary power supply 24 to enable. When the button switch S1 is released, the auxiliary power supply 24 can still work. When the electronic device is powered off, the microcontroller cancels the enable signal, the auxiliary power supply 24 stops working, and the entire system powers down to save power consumption.

[0064] in, Figure 7 R61, R62, and R63 are all resistors, C64 is a capacitor, and D65 is a diode.

[0065] In some embodiments, combined with Figure 7 , 5 And 6, such as Figure 7 The diagram shown is a schematic of an auxiliary power activation circuit in the system. This auxiliary power activation circuit includes: a switch-type RFID chip 21a, a first activation control module 22a, a power supply 23, and an auxiliary power supply 24. The first activation control module 22a includes:

[0066] Energy storage unit 221 is connected to auxiliary power supply 24 and is used to store the power when the electronic device 20 was turned on last time;

[0067] Control unit 222, connected to energy storage unit 221, is used to control switch unit 223 to turn on based on low-level signal output from open-drain pin OD and the amount of electricity stored in energy storage unit 221.

[0068] The switching unit 223 has a first end connected to the control unit 222, a second end connected to the battery 23, and a third end connected to the auxiliary power supply 24, and is used to further connect the battery 23 and the auxiliary power supply 24 when the switch is turned on.

[0069] In some embodiments, the auxiliary power activation circuit further includes a push-button switch S1. The first end of the push-button switch S1 is connected to the battery 23, and the second end is connected to the auxiliary power supply 24. When the push-button switch S1 is in the off state, the electronic device 20 is in the off state. The push-button switch S1 is also connected in parallel with the switch unit 223.

[0070] In some embodiments, such as Figure 7As shown in the above, the switch unit can include a PMOS; wherein the gate (G) of the PMOS is connected to the output end of the control unit 222, the source (S) of the PMOS is connected to the battery 23, and the drain (D) of the PMOS is connected to the auxiliary power supply 24. The control unit 222 is configured to output a low-level signal at the output end based on the first low-level signal output by the open-drain pin OD and the amount of electricity stored by the energy storage unit, so as to control the switch unit to be turned on.

[0071] As shown in the above Figure 7 The main role of the PMOS is to use the source (S) and the drain (D) terminals to bear the battery voltage, and the gate (G) is used to control the opening. When the gate-source voltage (Vgs) is less than 0 and Vgs

[0072] In some embodiments, as shown in the above Figure 7 As shown in the above, a resistor Rgs is arranged between the gate of the PMOS and the source of the PMOS. The resistor Rgs is used to make the Vgs of the PMOS equal to 0 when the PMOS does not need to be turned on, and the gate voltage (Vg) of the PMOS is equal to the battery voltage (Vbattery), so as to ensure that the PMOS is not turned on.

[0073] In some embodiments, as shown in the above Figure 7 As shown in the above, the energy storage unit can include a farad capacitor C1. One end of the farad capacitor C1 is connected to the control unit 222 and the auxiliary power supply 24, and the other end of the farad capacitor C1 is grounded (GND).

[0074] In some embodiments, as shown in the above Figure 7 As shown in the above, the energy storage unit can include a farad capacitor C1 and a diode D1.

[0075] As shown in the above Figure 7 In the above, the farad capacitor C1 is used to store electricity for the next activation of the power-on. The diode D1 is used to charge the farad capacitor C1 when the auxiliary power supply 24 is working, and to be reverse-biased to cut off the current when the auxiliary power supply 24 is not working, so as to prevent other circuits in the system from consuming the amount of electricity of the farad capacitor C1.

[0076] In the above, one end of the farad capacitor C1 is connected to the control unit 222 and the cathode of the diode D1, the other end of the farad capacitor C1 is grounded, and the anode of the diode D1 is connected to the auxiliary power supply 24.

[0077] In some embodiments, as shown in the above Figure 7 As shown in the above, the control unit 222 includes a PNP-type switching triode and an NPN-type switching triode.

[0078] The base (b) of the PNP type switch triode is connected to the open drain pin OD, the emitter (e) of the PNP type switch triode is connected to the energy storage unit, and the collector (c) of the PNP type switch triode is connected to the base (b) of the NPN type switch triode; the collector (c) of the NPN type switch triode is connected to the switch unit, and the emitter (e) of the NPN type switch triode is grounded.

[0079] Figure 7 The base (b) of the PNP type switch triode is connected to the open drain pin OD, the emitter (e) of the PNP type switch triode is connected to the energy storage unit, and the collector (c) of the PNP type switch triode is connected to the base (b) of the NPN type switch triode; the collector (c) of the NPN type switch triode is connected to the switch unit, and the emitter (e) of the NPN type switch triode is grounded. If the b end is , then e and c are turned on, so that the function of the switch can be realized. If the c end is high voltage, and the b end is , then c and e are disconnected; if the b end is high , then c and e are turned on, so that the function of the switch can be realized.

[0080] In some embodiments, Figure 1 As shown, a resistor Rb2 is arranged between the base of the PNP type switch triode and the open drain pin. The resistor Rb2 limits the current of the base of the PNP type switch triode.

[0081] In some embodiments, Figure 4 As shown, a resistor Rb is arranged between the collector of the PNP type switch triode and the base of the NPN type switch triode. The resistor Rb limits the base current of the NPN type switch triode.

[0082] In some embodiments, Figure 6 As shown, a resistor Rbe2 is arranged between the base of the PNP type switch triode and the emitter of the PNP type switch triode. The resistor Rbe2 provides a stable voltage for the base of the PNP type switch triode when the PNP type switch triode is not needed to be turned on, so that the PNP type switch triode is not floating and is guaranteed not to be turned on.

[0083] In some embodiments, Figure 8 As shown, a resistor Rbe is arranged between the base of the NPN type switch triode and the emitter of the NPN type switch triode. The resistor Rbe provides a stable voltage for the base of the NPN type switch triode when the NPN type switch triode is not needed to be turned on, so that the NPN type switch triode is not floating.

[0084] The above Figure 5When the RFID reader 10 does not control the switch type RFID chip 21a, the open drain pin OD of the switch type RFID chip 21a is in a high resistance state, the b electrode and e electrode voltage of the PNP type switch triode is close to the voltage of the farad capacitor C1, the PNP type switch triode is not conductive, the b electrode of the NPN type switch triode is 0V, and the NPN type switch triode is also not conductive. The gate-source voltage Vgs of the PMOS is 0V and not conductive.

[0085] The above Figure 7 When the RFID reader 10 controls the switch type RFID chip 21a to activate the power-on, the open drain pin OD of the switch type RFID chip 21a outputs a low level signal, the b electrode voltage of the PNP type switch triode is reduced, the PNP type switch triode is turned on, the b electrode of the NPN type switch triode is a high level signal, the NPN type switch triode is also turned on, the gate voltage Vg of the PMOS is pulled to a low level signal, Vgs<0, the PMOS is turned on, and the auxiliary power supply 24 is activated.

[0086] Because the switch type RFID chip is arranged in the auxiliary power supply activation circuit, and the chip can receive the external power-on instruction sent by the RFID reader, and output a low level signal to the RFID activation circuit through the open drain pin of the switch type RFID chip based on the power-on instruction, so that the RFID activation circuit can turn on the battery and the auxiliary power supply based on the low level signal, and then activate the auxiliary power supply, the auxiliary power supply can be activated without contact based on the above auxiliary power supply activation circuit. Therefore, in the case that the electronic device in which the auxiliary power supply activation circuit is located is free from unpacking, the auxiliary power supply therein can also be activated, so as to facilitate the power-on of the electronic device and software updating and other operations in the transportation and storage process.

[0087] In some embodiments, in combination with Figure 4 , Figure 8 and Figure 7 , as shown in Figures 1 to 3 , it is a schematic diagram of an unpacking-free electronic device power-on system Figure 2 In the system, the RFID chip 21 can be a switch type RFID chip 21a, the switch type RFID chip 21a includes an open drain pin OD connected between the battery 23 and the key switch S1, and the ground end (GND) of the switch type RFID chip 21a is connected between the key switch S1 and the auxiliary power supply 24.

[0088] In the embodiment of the application, when the battery voltage is less than the withstand voltage value of the open drain pin OD, the switch type RFID chip can be directly connected in parallel in the key power-on circuit, that is, the above Figure 3As shown. When the battery voltage is greater than or equal to the withstand voltage of the open-drain pin OD, an RFID activation circuit including a switch-type RFID chip and an activation control module can be set up, and then connected to the button power-on circuit to achieve the desired effect, as shown. Figure 9 As shown in the image.

[0089] For example, such as Figure 4 The open-drain voltage rating of the switch-type RFID chip shown above is typically around 5V. If the battery voltage is ≤5V, it is suitable for... Figure 2 If the battery voltage is 30V, the open-drain pin of the switch-type RFID chip cannot withstand the tens of volts voltage at the position of the push-button switch S1 in the original push-button power-on circuit 60 of the electronic device. Therefore, it is suitable for... Figure 9 To avoid damaging the device.

[0090] for Figure 9 The RFID chip in the text can be a power-output RFID chip, a special type of RFID chip capable of outputting power. It typically integrates a power conversion module, converting received radio frequency signals into stable electrical energy output. This type of chip has significant application value in certain special scenarios. For example, in environments where traditional power supplies are unavailable, or for small, low-power devices, power-output RFID chips can serve as a convenient power supply method. Through interaction with the reader, it continuously acquires energy and outputs it to connected devices, ensuring the normal operation of those devices.

[0091] In some embodiments, exemplary, combined Figure 3 and Figure 9 ,like Figure 10 The image shows a schematic diagram of a power-on system for electronic devices that does not require unpacking. Figure 10 The above. Figure 10 The RFID chip 21 in the middle can specifically be Figure 10 The activation control module 22 in the RFID activation circuit 20a of the medium power output type RFID chip 21b can specifically be... Figure 10 The second activation control module 22b is connected to the second activation control module 22b.
