And secondly, the full-charge battery pack and the insufficient-charge battery pack are stored in two places, so that the defects that in the prior art, a single pack is difficult to identify and a card jamming or collision easily occurs in a battery replacement machine due to a complicated stacking structure of the battery pack in a charging and replacing integrated mode are overcome.

Thirdly, the design of the centralized charging field and the pallet truck makes the supply of the battery pack to the power exchanging station flexible, how many full-charge battery packs are needed by the power exchanging station, and how many full-charge battery packs can be supplied by the combined operation of the charging field, the pallet truck and the transport vehicle, so that the problem that the demand of the power exchanging operation on the full-charge battery packs cannot be met because the replaced insufficient-charge battery packs cannot be charged quickly in the power exchanging structure integrating charging and exchanging is avoided.

Fourthly, the concentrated charging field can be far away from urban areas or blocks with high population and building density, so that the concentrated charging field is less limited by the capacity of a power grid, potential safety hazards in the charging process are correspondingly reduced, urban planning and approval of an electric power department are easily obtained, the concentrated charging field is high in practicability and easy to popularize.

And fifthly, the operation and control center exchanges data with each battery pack in each battery changing station, the centralized charging station and the transfer link through the battery pack monitoring and diagnosing device, so that intelligent management of the battery packs is realized.

Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that variations, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the scope of the present invention.
