Abstract： In the process of cognition and exploration of the ocean, underwater observation and detection equipment is the necessary facility to enter and detect the ocean. These types of equipment provide technical support for the development and utilization of marine resources and is an important grip for the implementation of China’s marine strategy and the construction of a strong marine country. However, limited by the current level of energy supply, the underwater equipment has problems such as single operation capacity and short single endurance time, which cannot meet the needs of long-term operation under complex working conditions. As the development of marine resources and the defense of sea frontiers in various countries in the world are becoming more and more intense, the construction of transparent marine engineering and submarine factories urgently need to build intelligent underwater equipment clusters, and urgently need energy and power support with high energy density, high safety, high reliability, and long life. Therefore, we need to innovate the underwater energy supply model, build a powerful underwater energy base station with multiple complementary functions of “generating, storing, transmitting, and using”, and overcome the technical bottleneck of underwater energy supply, Providing sufficient energy and power for intelligent and clustered underwater equipment to better assist the construction of China’s marine capability.
