Description

Technical Field

[0001] The present invention relates to the field of battery replacement for new energy ships, and in particular to a power battery cabinet system and a use method for a flexible charging and battery replacement mode for new energy ships. Background Art

[0002] With the rapid development of new energy ship technology, the installation forms of battery packs for electric ships are mainly divided into two types: fixed charging type and battery replacement type. Fixed charging battery packs are installed in fixed cabins and need to be charged at fixed places such as docks. Although this method is simple, it limits the operational flexibility and endurance of the ship to a certain extent. The battery replacement battery pack is integrated in a battery cabinet or container, which can be charged at a fixed location and can also be quickly replaced by replacing the battery pack, thereby significantly improving the operational efficiency of the ship.

[0003] Therefore, there is an urgent need for a power battery cabinet system and a method of use for flexible charging and swapping modes for new energy ships to solve the above problems. Summary of the invention
