"Greater Bay Area No.1" was built by China Merchants, loaded with a hybrid electric propulsion system jointly developed by China Merchants, CRRC and Contemporary Ampere Technology Co., Ltd., with completely independent intellectual property rights, which indicates that China has the ability to independently research, develop, design and manufacture electric cruise ships at sea.
It is understood that "Greater Bay Area No.1" has a length of 7 1.95 meters, a width of 18.72 meters, a designed draft of 2.57 meters, a passenger quota of 350 people, an operating speed of 14 knots and a full displacement of 1.350 tons.
"Greater Bay Area No.1" will travel between Shenzhen, Hong Kong and Macao. Each voyage lasts for 4 hours, including a 40-minute pure electric journey. The brand-new hybrid power setting makes the ship reach the standard of "ultra-low emission, ultra-low pollution and ultra-low noise".
"Greater Bay Area No.1" is equipped with the power battery system of contemporary Amperex Technology Co., Ltd., and the whole ship has 144 high-energy density battery pack, using advanced CTP(cell? Where to? Pack) has no modular technology, and the total power reaches 2520kWh, which is equivalent to the power of 200 hybrid cars.
In terms of layout, the battery compartment is located on both sides of the bow bottom compartment, and air conditioning is installed in the compartment to control the temperature at 25 2℃, which is conducive to the best performance of the battery.
The most important concern of marine power battery system is safety. As the first power battery enterprise in China to pass the latest inspection guide of China Classification Society (CCS), "Inspection Guide for Pure Battery Powered Ships" (including batteries, battery packs and battery management systems), the products of Contemporary Amp Technology Co., Ltd. have multi-layer monitoring and alarm functions from the battery to the system level, ensuring the safety and reliability of the products in an all-round way.
For "Greater Bay Area No.1", the battery pack adopts IP67 design, which can effectively avoid the potential safety hazards caused by water vapor, salt fog and dust. At the same time, the battery pack shell is made of high-strength steel plate, which conforms to the relevant specifications of classification society and successfully passes the relevant safety tests such as vibration, mechanical impact, simulated collision and fire.
