Description

Technical Field

[0001] The utility model relates to a battery series packaging device with a separation and connection function, belonging to the technical field of battery production. Background Art

[0002] During battery production, multiple small batteries are often packaged in series to increase the overall voltage of the battery pack. This method significantly increases the voltage output of the battery pack by combining multiple single cells, meeting higher energy demand in applications.

[0003] However, existing small batteries are packed tightly together, often with minimal spacing between adjacent cells. During transportation, storage, or use, small batteries can easily collide with each other if the battery pack is subjected to external vibrations or impact. Such collisions can not only cause physical damage such as breakage of the battery casing and leakage of internal electrolyte, but in severe cases, can also generate an arc at the moment of impact, posing a safety hazard. Arcing can not only damage the battery itself but also pose a threat to the surrounding environment and equipment, compromising the safety and reliability of the battery pack.

[0004] Therefore, a packaging structure that can effectively prevent collisions between batteries to improve safety performance is needed. Utility Model Content
