3A1-I14 Development of a noncontact charging system by electromagnetic field resonant coupling for long-term deployment of a hovering type AUV(Research News)

Abstract

Battery capacity is a bottleneck for long-term deployment of an AUV. Recently, the use of a seafloor station has been proposed for extended deployment of an AUV. This paper reports about a development of noncontact charging system by electromagnetic field resonant coupling for long-term development of a hovering type AUV. It was experimentally verified that the system can send about 200W of electricity through seawater at the gap of 15mm.
