At present, there have been relevant studies on battery-powered ships at home and abroad, but they are all for cruise ships, scientific research ships, ferries, short-distance fixed-route cargo ships and other ship types, and have not yet been applied to dredgers. The working areas of dredgers are mostly located near ports and coastal areas. The use of battery power will greatly reduce the pollution caused by their emissions, which is of great significance to improving the coastal atmospheric environment and water environment. At present, the construction and design of battery-powered ships is still in its early stages. The current electric ships are still a simple replacement of energy power. The layout of battery-powered ships needs to be designed according to the performance characteristics of electric energy. Summary of the invention
