[0021] The specific embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this disclosure.

[0022] Figure 1 This is a schematic diagram of an emergency start smart clip circuit according to an exemplary embodiment of the present disclosure. Figure 1 As shown, the circuit includes: a power supply module, a control module, a clip recognition module, a start recognition module, and a forced output module; The input terminal of the power module is connected to the emergency start-up power supply, and the output terminal of the power module is connected to the control module to provide power to the control module. The clip recognition module is connected to the control module and is used to detect whether the clip is correctly clamped on the battery terminal and send the detection result to the control module. The start-up identification module is connected to the control module and is used to detect whether the vehicle is started. The detection result is sent to the control module to indicate whether the vehicle has started.

[0023] It should be noted that in this embodiment, a startup identification module is used to detect the voltage signal in the circuit during vehicle startup. For example, when the vehicle is not started, the voltage signal detected by the startup identification module is a continuous high voltage; during vehicle startup, a decreasing voltage signal is generated in the circuit. When the startup identification module detects this decreasing voltage signal, it determines that the vehicle has started, generates a detection result, and sends the detection result to the control module. This detection result indicates that the vehicle is currently in a startup state.

[0024] For example, when a vehicle starts, the voltage in the onboard circuit drops. The start-up detection module recognizes this voltage drop and sends the detection result to the control module. The control module responds to this result by inputting a corresponding current to the vehicle battery to help start the vehicle. Once the battery voltage rises after the vehicle starts, the control module will cut off the current output to prevent unnecessary output, allowing the device to start the vehicle more times with the same capacity.

[0025] The forced output module is connected to the control module and is used to output emergency power when an emergency start signal is received from the control module.
