Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting, in particular to a fire suppression device for a ship battery pack. Background Art

[0002] With the increasing world energy consumption and the increasing environmental pollution, lithium-ion batteries have gradually occupied an important position in transportation fields such as electric vehicles and electric ships. Electric ships driven by lithium-ion batteries have been widely used in inland ferries, short-distance passenger ships, sightseeing cruise ships and small yachts. Unlike electric vehicles, ship batteries need a large total storage energy to meet their driving power and endurance requirements. High energy density also means that ship batteries face a higher risk of thermal runaway. Moreover, due to the limitations of the navigation environment, once a fire occurs on a ship, it is difficult for external forces to rescue. It can be seen that ships have stricter fire prevention measures for battery thermal runaway, and the current fire suppression devices for electric vehicles cannot be directly applied to electric ships. Therefore, there is an urgent need for a battery pack fire suppression device suitable for ships. Utility Model Content
