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

A coil layout of wireless power transfer systems based on multicoil arrangement for underwater vehicles

“…Normally, UVs are hoisted on board a mother vessel for battery charging or replacement, which involves dangerous manipulations as well as operating costs. On the other hand, there are studies on charging via wireless power transfer (WPT) from an undersea power supply station . In so doing, exploration and battery charging cycles can be completed under water, without increasing capacity of installed batteries, thus considerably improving activity life and usefulness of UVs.…”

“…On the other hand, there are studies on charging via wireless power transfer (WPT) from an undersea power supply station. [1][2][3][4][5] In so doing, exploration and battery charging cycles can be completed under water, without increasing capacity of installed batteries, thus considerably improving activity life and usefulness of UVs. However, one needs a mechanism to fix (dock) UVs to avoid coil misalignment.…”
