  "textContent": "An unlocking circuit for a charging station when powered off is provided. A microcontroller unit outputs a first level signal and a second level signal when an auxiliary power supply is cut off. A first signal processing circuit receives the first level signal and converts the first level signal into a first control signal for unlocking an electronic lock. A second signal processing circuit receives the second level signal and converts the second level signal into a second control signal including information about action effectiveness of the electronic lock. An action execution circuit receives the first control signal and the second control signal, and responds to the first control signal and the second control signal to unlock the electronic lock.",
