In some embodiments, the dimension of the first battery holder 42 is smaller than the dimension of the second battery holder 43 in the second direction Y.

The first battery rack 42 has a smaller size in the second direction Y relative to the second battery rack 43, so as to reserve a space on one side of the first battery rack 42 in the second direction Y, and facilitate the staff to enter the cabin 41 for maintenance.

In some embodiments, the plurality of first storage areas 421 and the plurality of second storage areas 431 are arranged to be shifted in the second direction Y.

An edge of the first storage region 421 in the second direction Y does not overlap an edge of the second storage region 431 in the second direction Y in the first direction X.

The pick and place mechanism 45 is movable in the second direction Y to pick and place the batteries 11 of different storage locations 4 a. The first storage area 421 and the second storage area 431 are disposed in a staggered manner in the second direction Y, so that the pick-and-place mechanism 45 can stay at different positions when picking and placing the battery 11 in the non-stop storage area, thereby facilitating the positioning control of the system on the pick-and-place mechanism 45.
