[0002] In recent years, green and low-carbon shipping solutions have been sought globally, and the development of new energy ships has been strong. As the main power system of a ship, the technical level of the battery pack directly affects the performance, safety, economy, and environmental friendliness of new energy ships.

[0003] Currently, the installation structure of ship battery packs is mostly fixed-mounted, and the battery packs are fixedly connected to the ship's hull, resulting in low space utilization, difficult maintenance, and relatively low safety. Due to the influence of external environmental factors such as wave impact on the ship, the traditional fixed installation method is difficult to effectively absorb vibration and shock, leading to an increase in the self-loss of the battery pack, and the safety risk cannot be ignored.

When the ship shakes, the installation position of the battery pack is prone to displacement or even tipping, and the battery arrangement is messy, making management and maintenance inconvenient.

[0005] Single fixing method: The battery may be fixed only from a single direction, unable to effectively prevent the battery from bouncing up and down, moving forward and backward, or shifting left and right during operation, and it is difficult to adapt to batteries of different sizes.

[0006] Low operation efficiency: It mostly relies on manual operation, the process is cumbersome, the efficiency is low, and it cannot be accurately controlled, making it difficult to meet the requirements of complex working conditions.
