Claim 18:
19. The battery swapping method of claim 17, characterized in that there are at least two magnetic field sensors mounted on the quick swapping support of the electric vehicle, one of the magnetic field sensors arranged on the bottom surface of the quick swapping support of the electric vehicle, senses the magnetic field of a magnetic steel in a longitudinal direction to determine whether the battery pack is moved and mounted in place in the longitudinal direction; the battery swapping method also comprises:
when no magnetic field is sensed by the magnetic field sensor arranged on the bottom surface of the quick swapping support of the electric vehicle, 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 arranged on the bottom surface of the quick swapping support of the electric vehicle, reaches the preset intensity value, the magnetic field sensor generates a stopping instruction and send 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 upward according to the stopping instruction.
