At 12:3 on March 29, 2022, with the sound of a ship whistle, the pure electric (lfp battery) cruise ship with the largest capacity in the world and the world’s first charging technology – “Three Gorges of the Yangtze River 1” successfully berthed in Sandouping Port in the Three Gorges Reservoir Area successfully completed its maiden voyage.Lfp battery cruise,,largest pure ,electric cruise ship, lfp battery , maiden voyage
“Three Gorges of the Yangtze River 1” is 100 meters long, 16.3 meters wide, and has a rated capacity of 1,300 passengers. At 9:58 a.m. on the same day, he set off from the Three Gorges Project Dam and arrived after sailing for 9 kilometers. After testing, all indicators are normal after the cruise ship’s maiden voyage. Captain Chen Guohai said excitedly: “The cruise ship is less noisy, and the driving experience is better than traditional cruise ships.”
1. Lfp battery cruise ship power heart
“Three Gorges of the Yangtze River 1” is a pilot project of the Ministry of Transport and a high-tech ship research project of the Ministry of Industry and Information Technology. The cruise ship is a major achievement of the joint efforts of Yangtze Power and Hubei Three Gorges Tourism Group to promote the protection of the Yangtze River. The total investment of the project is 150 million yuan, which has attracted many domestic scientific research institutes and enterprises to jointly participate in the research and has independent intellectual property rights.
The chairman of Keheng New Energy said that the key marine technologies such as DC networking safety control based on large-capacity power batteries adopted by cruise ships have been overcome after five years of scientific research. The manufacturing difficulty is unprecedented. There is no ready-made template for cruise ship construction. Standard is blank.
The power “heart” of the cruise ship is divided into 4 battery compartments equipped with 720 Ningde era lfp power battery packs, with a total capacity of 7,500 kWh.
Xu Junjie, general manager of China Classification Society Yichang Branch, told reporters that based on the statistical data of China Classification Society and the world’s major classification societies, the electric cruise ships were generally within 3,000 kWh of electricity before. The largest capacity in the world.
2. Decryption of lfp battery cruise charging technology
“The larger load capacity forces us to make breakthroughs in charging technology.” Liu Jun, the project technical leader, said that the R&D team took the lead in launching the “high-voltage charging + low-voltage power supply” scheme in the world after comprehensive comparison and selection. Equipped with 10 kV port charging facilities and on-board high-voltage transformers to effectively transform onshore high-voltage electricity for the use of cruise ship power distribution systems, thereby solving charging problems. After repeated tests, it takes 7 to 8 hours to be fully charged, and it can last for 10 hours and 100 kilometers normally.
In view of the fact that the ship does not consume fuel during the entire voyage, the Municipal Transportation Bureau estimates that compared with traditional powered ships, the cruise ship can replace 530 tons of fuel oil and reduce various harmful gas emissions by 1,660 tons per year.
According to data from the Maritime Safety Administration of the Ministry of Transport, there are currently 96,049 passenger ships, cargo ships and tankers in the Yangtze River basin, most of which use traditional power. Wang Ming, director of the Comprehensive Transportation Research Institute of the National Development and Reform Commission, said that the maiden voyage of the “Three Gorges 1” has provided a new solution for “electrifying the Yangtze River”, and has also expanded space for accelerating the cultivation of the new energy ship industry, which will effectively boost the transportation power of the country. , green transportation construction and the realization of the “dual carbon” goal.

3. Exclusive Review of Lfp Battery Cruise News
As the largest and most important marine waterway transportation, ships play a leading role in transportation. Electric energy is the general trend and meets environmental protection requirements. There is huge room for technological development. the higher the coefficient.
China has a vast territory and oceans and rivers provide application space for shipping, and economic development is inseparable from water transportation. China’s pursuit of wealth is inseparable from transportation, and the high-efficiency of transportation will definitely continue to invest in research.
The inaugural voyage of the pure electric lfp battery cruise ship with the largest capacity in the world we have seen is just the beginning of the shipping of lfp batteries.
