Description

Technical Field

[0001] The present invention relates to the technical field of battery swapping cabinets, and particularly to a battery swapping cabinet with multi-layer protection and a protection method. Background Art

[0002] The battery swapping cabinet is used to perform battery swapping operations. For example, when the battery of an electric two-wheeler is depleted, the discharged battery is removed and placed in the battery swapping cabinet for charging, and a fully charged battery of the same model is taken out from the battery swapping cabinet for replacement to facilitate travel. A battery swapping cabinet corresponds to multiple batteries and multiple chargers. Since different batteries are charged cyclically, it is necessary to monitor and control each battery and each charger during this process to avoid situations such as battery overheating, overcurrent, overvoltage, etc., which may cause explosion or inability to use.

[0003] However, the existing battery swapping cabinets only adopt a single layer of protection, that is, simply judge whether the data collected by the sensor exceeds the threshold. Although some fault signals can be captured in this way, it is impossible to comprehensively and accurately reflect the real situation of the battery swapping cabinet and take good protection measures, thus there are certain potential safety hazards.
