Although this type of connection can meet the electrical connection requirements to some extent, it has many drawbacks. On the one hand, threaded connection is tedious to operate. During installation and disassembly, the worker needs to spend a lot of time rotating the nut or bolt, which greatly reduces the work efficiency, especially in the deployment and maintenance of large-scale energy storage equipment. On the other hand, the threaded connection is prone to looseness over time, especially when affected by external factors such as equipment operation vibration, thermal expansion and contraction caused by temperature changes, the looseness is more obvious. This not only leads to poor electrical contact, causing increased resistance, heating and even arc and other safety hazards, but also may greatly reduce the operation stability of the entire energy storage system.
