All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an intelligent ignition clip according to an embodiment of the present invention, which can be used in an electronic system requiring ignition starting, such as an automobile or a yacht, for connecting an external starting power source (e.g., a portable or handheld power source) to a battery of the automobile or the yacht to start an engine thereof. The following description takes the example of an automobile ignition, and the smart ignition clip includes two ignition clips: a first ignition clamp 11 and a second ignition clamp 12. The two ignition clamps 11 and 12 are used for being connected with a storage battery of the automobile. The intelligent ignition clamp further comprises a power supply access end (not shown) for plugging and connecting with the output port of the starting power supply.

The storage battery of the automobile is divided into a positive pole and a negative pole. When the intelligent ignition clamp connects the starting power supply with the automobile battery, one of the first ignition clamp 11 and the second ignition clamp 12 is a positive ignition clamp, and the other is a negative ignition clamp.

That is, for any ignition clamp, there is no difference between the positive and negative electrodes before the circuit is turned on, and it can be connected to the positive electrode of the battery or the negative electrode of the battery. That is, the first ignition clamp 11 may be connected to the positive electrode of the battery, and the second ignition clamp 12 may be connected to the negative electrode of the battery to achieve conduction. Or the first ignition clamp 11 is connected with the cathode of the battery, and the second ignition clamp 12 is connected with the anode of the battery to realize conduction. When the two ignition clamps are connected with the battery, the clamp polarity detection module 14 is used for detecting the polarities of the battery respectively connected with the two ignition clamps.
