Description

As the core facility of this technology, the efficient and safe operation of battery swap station is crucial to the healthy development of electric vehicle industry.

[0003] However, in the daily operation of battery swap station, the abnormal monitoring and processing of battery pack become a problem to be solved. Since a large number of battery packs are densely stored in the battery compartment of battery swap station, once abnormal battery such as overheating, short circuit and other safety hazards is monitored, it must be quickly and safely removed from the battery compartment to avoid potential accident risks. At the same time, considering the compactness of the structure of battery swap station and the weight of battery pack itself, the traditional manual handling method is not only inefficient, but also has great safety hazards.
