最近的技术进步使无人水下航行器具有更大的自主性，使其能够在越来越深和更困难的环境中执行更长的任务。虽然这些车辆在收集和处理数据时可以自行导航，但仍然需要人工干预来补充电力供应。除非这些车辆中的能源能够在无需人工干预的情况下得到补充，否则真正的自主长期任务可能会很困难。 WiTricity Corporation 一直在各种市场开发无线和自动充电解决方案，包括研究使用高谐振无线功率传输 (HR-WPT) 技术支持将数千瓦电力无线传输到无人水下航行器 (UUV) 等车辆的可行性。高谐振无线功率传输可以通过多种材料（包括盐水）进行功率传输。 HR-WPT 系统封装在密封外壳中，可以通过水传输几千瓦的电力，同时消除了对容易发生故障的湿插接连接器的需求。此外，由于 HR-WPT 系统可以在设备移动时有效地向设备传输电力，因此 UUV 等设备只需漂浮在码头或其他配备无线电源的平台旁边即可充电。具有不同相对位置和方向的源和设备之间的高效无线功率传输消除了对紧密机械耦合的需要，并允许在水下物体之间安全、可靠和高效地传输功率。
Recent technological advances have allowed unmanned underwater vehicles to act with more autonomy, allowing them to embark on longer missions to increasingly deeper and more difficult environments. While these vehicles can navigate themselves as they collect and process data, human intervention is still required to replenish their power supplies. Truly autonomous long-duration missions will likely be difficult until the energy sources in these vehicles can be replenished without human intervention. WiTricity Corporation has been developing wireless and automatic charging solutions in a variety of markets, including investigating the feasibility using Highly Resonant Wireless Power Transfer (HR-WPT) technologies to support the transfer of several kilowatts of power wirelessly to a vehicle such as an unmanned underwater vehicle (UUV). Highly resonant wireless power transfer can enable power transfer through a variety of materials, including saltwater. A HR-WPT system, encased in a hermetically sealed enclosure, could transfer several kilowatts of power through water while eliminating the need for failure prone wet-mate connectors. Additionally, because HR-WPT systems can transfer power efficiently to devices as they move around, devices such as UUVs could be recharged simply by floating alongside a dock or other platform that has been outfitted with a wireless power source. The high efficiency wireless power transfer between sources and devices with varying relative positions and orientations removes the need for tight mechanical coupling and allows for power to be transferred between objects underwater safely, reliably, and efficiently.
