Development of a Novel Charging Station for Underwater Power Supply to Rotating Auvs

This paper presents a novel charging Station for Underwater Power Supply to Rotating AUVs. The new charging station is mainly designed to solve the problem of low energy density of lithium batteries carried by existing charging stations, which limits the number of times the charging station can supply the AUVs. The station has utilized lithium battery system, closed hydrogen oxygen fuel cell system, and wireless energy transmission device. The platform adopts DC power supply network structure to facilitate the grid connection operation of different energy systems. To avoid flooding of fuel cells and extend their operating cycle, the reverse pulse of exhaust gas simultaneously to the anode and cathode method is utilized. Meanwhile, in order to adapt to the structural configuration of AUVs, a wireless charging system based on full Rotary conversion coil is designed. The composition architecture, structural form, electrical architecture, fuel cell system, and wireless energy transmission system of the station are introduced and analyzed. A test prototype is built in the lab and the charging effect is simulated.
