Claim 19:
20. The battery swapping method of claim 19, characterized in that another magnetic field sensor arranged on a side wall, near the head of the electric vehicle, of the quick swapping support of the electric vehicle, determines whether the battery pack is moved and mounted in place in a transverse direction, the battery swapping method also comprises:
the master control unit controls the battery pack disassembly and assembly unit to push the battery pack toward the head of the electric vehicle along a preset path such that the battery pack is inserted into the battery pack mounting groove, in this case, the magnetic field sensor arranged on the side wall, near the head of the electric vehicle, of the quick swapping support of the electric vehicle senses the magnetic field generated by the magnetic steel;
when the intensity of the magnetic field sensed by the magnetic field sensor arranged on the side wall, near the head of the electric vehicle, 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 according to the stopping instruction.
