Claim 17:
18. The battery swapping method of claim 17, characterized in that a magnetic field sensor mounted on the quick swapping support of the electric vehicle senses the magnetic field which is generated by a magnetic steel arranged on the charged battery pack; the battery swapping method also comprises:
when no magnetic field is sensed by the magnetic field sensor or the intensity of the sensed magnetic field does not reach a preset intensity value, the battery pack disassembly and assembly unit continues to lift the battery pack upward;
when the intensity of the magnetic field sensed by the magnetic field sensor reaches the preset intensity value, the magnetic field sensor generates a stopping instruction and sends the stopping instruction to the master control unit by means of the signal transmission unit;
the master control unit stops the movement of the battery pack disassembly and assembly unit according to the stopping instruction.
