With the rapid development of smart water conservancy, environmental monitoring, water rescue and other fields, unmanned ships, as the core carrier of intelligent water operations, are facing the dual challenges of "endurance anxiety" and "operation efficiency". Traditional plug-in charging requires manual intervention, which not only increases operation and maintenance costs but also poses safety risks during bad weather or night operations. WIRELESSPT has been deeply engaged in industrial-grade wireless charging technology for many years. The unmanned vessel wireless charging solution it has launched for unmanned vessel application scenarios, with the three major advantages of "autonomy, high reliability, and anti-interference", redefines the energy supply mode of unmanned equipment on water.

Industry pain point: The "bottleneck" problem of unmanned vessel charging

The working environment of unmanned vessels is complex. Factors such as water surface fluctuations, water quality pollution, and bad weather all pose strict requirements for the charging system. The traditional charging method relies on manual connection, resulting in short single operation time and frequent task interruption. Especially in long-term tasks such as environmental monitoring and cross-regional inspection, the short battery life directly restricts the efficiency of data collection. Data from a certain environmental monitoring agency shows that for unmanned vessels that use manual charging, the effective operation time accounts for less than 60%, with the rest of the time spent on charging during the return journey.

The Lu-Yu Solution: Three major technological innovations Solve Industry Challenges

The WIRELESSPT unmanned vessel wireless charging solution is based on magnetic resonance coupling technology and achieves breakthroughs through the following innovations:

1. Dynamic alignment adaptive technology: It adopts a dual-coil design and infrared + visual collaborative positioning, allowing for ±15° horizontal deviation and ±50mm vertical distance error, adapting to the attitude changes of unmanned vessels in waves, with a docking success rate of over 99.5%.

2. Fully sealed waterproof structure: Both the charging transmitter and receiver reach IP68 protection level, allowing for long-term operation at a water depth of 1.5 meters. The casing is made of 316L stainless steel, with corrosion resistance meeting the requirements of seawater environments.

3. Intelligent power regulation system: Automatically matches 500W to 3kW charging power based on the battery status (SOC) of the unmanned vessel. The charging efficiency is stable at 85% to 90%, and a 10kWh battery pack can be fully charged within 3 hours, which is 40% more efficient than traditional charging methods.

Practical Value: From "Manual Intervention" to "Unmanned Closed Loop"

An application case of a certain water conservancy monitoring project shows that after the deployment of the wireless charging solution between Shandong and Chongqing, unmanned vessels have achieved full-process autonomy of "returning to work, charging and setting off again". The single mission duration has been extended from 8 hours to 16 hours, the average monthly operation days have increased by 12 days, and the labor cost has been reduced by 60%. In addition, the solution supports multi-ship shared charging base stations and achieves efficient energy distribution through an intelligent dispatching system, further reducing the initial investment of the project.

Future Outlook: Building an energy network for unmanned systems on water

The technical director of WIRELESSPT stated: "Wireless charging for unmanned vessels is not merely an upgrade of a single device; it is the foundation for the large-scale application of unmanned systems on water." We are collaborating with universities to develop an integrated module for underwater wireless charging and data transmission. In the future, it will be possible to provide energy supply when unmanned ships and underwater robots work together, promoting the advancement of intelligent water equipment towards "multi-machine linkage and all-domain perception".
