Description

Marine battery pack with anti-collision protection design Technical Field The utility model relates to the technical field of ship energy storage equipment, in particular to a ship battery pack with an anti-collision protection design. Background With the development of ship electric technology, the safety and reliability of the marine battery pack serving as a core component of a ship power or energy storage system directly influence the running performance of a ship. In the sailing process of a ship, complex external environment challenges are often faced, namely, on one hand, when the ship is impacted by waves, the ship body shakes and accidentally collides, the battery pack needs to bear high-frequency vibration and external impact force, and on the other hand, the conditions of foreign matter collision (such as ship body parts, loading and unloading tools and the like) and bottom friction and the like possibly existing in a ship operation scene can threaten the structural integrity of the battery pack. However, the existing marine battery packs have the following disadvantages in the crash protection design: First, connector assemblies (e.g., charge and discharge plugs, communication interfaces, etc.) are typically directly exposed to the surface of the housing, lacking a targeted protective structure. When the battery pack collides or is accidentally scratched, the connector is easy to damage due to direct stress, so that the charge and discharge are interrupted, the communication is failed, and even the short circuit is at risk. Secondly, the traditional battery pack box body adopts common metal plates, and the top and bottom impact resistance is weak. When the top is impacted by falling objects or the bottom is rubbed with the ship body, the box body is easy to deform, and the internal battery module can be extruded, so that safety problems such as short circuit or thermal runaway and the like are caused. Thirdly, the installation area of the battery module lacks effective positioning and supporting structures, and the battery module is easy to shift or collide with each other when the ship shakes, so that internal circuit breakage or module damage can be caused, and the whole service life of the battery pack is influenced. Therefore, there is a need for a marine battery pack with multiple crash protection, connector hiding protection and stable battery module support to improve the impact resistance and operational reliability in a complex marine environment.
