Description

Technical field:

[0001] The present invention relates to the technical field of ship battery power systems, and in particular to an adaptive mounting system and method for a ship power battery pack. Technical background:

[0002] With the increasing global awareness of environmental protection and the pursuit of a low-carbon economy, the shipbuilding industry is gradually transforming to an all-electric propulsion system. Compared with traditional fuel propulsion systems, all-electric propulsion technology has the advantages of high efficiency, environmental protection, and low noise. Lithium batteries have become an important energy storage device in ship electric propulsion systems due to their high energy density, long service life, and excellent charging and discharging performance.

[0003] In the actual ship design and construction process, the installation of lithium battery packs has extremely high requirements for accuracy and safety. Usually, the lithium battery system consists of multiple battery packs, which need to be installed one by one in the designated slots in the iron frame system. The existing installation methods often rely on manual operation or semi-automatic equipment. The operation process is time-consuming and labor-intensive, and due to alignment deviation, it is easy to cause inaccurate installation of the battery pack and the iron frame slot, and even the lithium battery pack may be damaged and cause dangerous situations such as fire, which greatly damages the stability of the system.
