[0047] Specifically, the first resistor R1 and the second resistor R2 divide the voltage of the driving signal output by the input and output pins of the electronic tag chip 20, and the voltage divided on the second resistor R2 drives the first switch tube Q1 to turn on. The second resistor R2 can also function as a discharge resistor when the first switch tube Q1 is turned off, ensuring that the first switch tube Q1 can be reliably turned off. The first capacitor C1 is used for filtering.

[0048] In some embodiments, the second switch unit 32 includes a second switch tube Q2.

[0049] The first end of the second switch tube Q2 is connected to the first switch unit 31, the second end of the second switch tube Q2 is connected to the power supply 200, and the third end of the second switch tube Q2 is connected to the controller 300.

[0050] In this embodiment, the second switch tube Q2 is taken as an example of a PMOS tube. The first end of the second switch tube Q2 is the gate of the PMOS tube, the second end of the second switch tube Q2 is the source of the PMOS tube, and the third end of the second switch tube Q2 is the drain of the PMOS tube.

[0051] In addition, the second switch tube Q2 can be any controllable switch, such as an insulated gate bipolar transistor (IGBT) device, an integrated gate-commutated thyristor (IGCT) device, a gate turn-off thyristor (GTO) device, a silicon controlled rectifier (SCR) device, a junction gate field-effect transistor (JFET) device, a MOS-controlled thyristor (MCT) device, etc.

[0054] Specifically, when the first switch tube Q1 is turned on, the fourth resistor R4 and the voltage stabilizing diode D1 are connected in parallel to divide the voltage of the power supply 200 with the third resistor R3, and the voltage of the power supply 200 after being divided by the combination of the fourth resistor R4 and the voltage stabilizing diode D1 drives the second switch tube Q2 to be turned on. The fourth resistor R4 can also function as a discharge resistor when the second switch tube Q2 is turned off, ensuring that the second switch tube Q2 can be reliably turned off. The voltage stabilizing diode D1 also functions to clamp the voltage at the second end of the second switch tube Q2 when the voltage of the power supply 200 is too high, reducing the risk of damage to the second switch tube Q2 due to excessive voltage, thereby protecting the second switch tube Q2.

[0055] In this embodiment, when it is necessary to upgrade the energy storage product including the activation circuit 100, an external signal can be generated by an external device, the external signal is received by the antenna 10 and input to the electronic tag chip 20. Then, the electronic tag chip 20 outputs a driving signal, the driving signal is divided by the first resistor R1 and the second resistor R2 and then acts on the first switch tube Q1 to turn on the first switch tube Q1. The combination of the power supply 200, the voltage stabilizing diode D1 and the fourth resistor R4, and the third resistor R3 and the first switch tube Q1 form a path, and the power supply 200 acts on the second switch tube Q2 after being divided by the combination of the voltage stabilizing diode D1 and the fourth resistor R4 and the third resistor R3 to turn on the second switch tube Q2. At this time, the electrical connection between the power supply 200 and the power conversion module 40 is established, and the power conversion module 40 converts the voltage of the power supply 200 into a first voltage. Then, based on the first voltage, an activation signal can be generated to the controller 300 to activate the controller 300, and then subsequent upgrading of the energy storage product can be realized.
