Warmly congratulate the R&D project of key technologies and devices of solar photovoltaic system for inland ships of our company on winning the second prize of Science and Technology Award of the Chinese Society of Navigation

The 2017 annual review meeting of the Science and Technology Award of the Chinese Society of Navigation was held in Nanjing from November 28 to 30. After the review by the review committee according to the relevant provisions, methods and procedures, the research and development project of key technologies and devices of solar photovoltaic system for inland ships of Shandong Bos Energy Technology Co., Ltd. won the second prize.

The focus of green ship technology is the use of clean energy. Solar ship is one of the representative green ship technologies with energy conservation and emission reduction potential. This achievement has improved the theoretical methods of efficient transformation, inversion and charge discharge control of ship photovoltaic power, broken through the key technologies such as power tracking control, double closed-loop repetitive inverter control, charge discharge control and automatic power supply management of solar photovoltaic power generation for inland ships, and developed four core equipment necessary for ship photovoltaic systems, including marine high-power photovoltaic controller, photovoltaic inverter, large capacity lithium battery energy storage system and solar power monitoring system, It has also obtained the product certificate of China Classification Society, formed a complete set of solar photovoltaic system technology for inland ships with independent intellectual property rights, and has been applied to inland ships such as “Anji 204” and other inland ships such as Yangtze River water intake barges. The overall application of “Anji 204” has become the first operating ship awarded the “green ship” and “solar assisted power energy” marks by China Classification Society.
