【 摘 要 】

With the development of wave energy extraction technology, the performance requirements of wave energy converters have also become higher in order to maximize operating efficiency and the use of wave energy. In this paper, the wave energy characteristics and energy storage characteristics of current common wave energy converters are studied for this demand. Because small-scale wave energy convertors are characterized by their strong mobility and relatively lower power generation, it is not easy to integrate the generated energy directly into the power grid. Therefore, a small, highly efficient and environmentally friendly storage method is needed. Through investigation, the lithium battery pack is used to store the energy output from the convertors by means of a filtered regulated charging circuit.
