In the current era where intelligent manufacturing and smart logistics are continuously extending to dark factories and special scenarios, the autonomous endurance capabilities of mobile robots, AGVs, and inspection equipment directly determine whether the automated production lines can truly achieve closed-loop implementation. Traditional induction-type wireless charging has strict requirements for docking and positioning accuracy, and even a slight deviation can cause a sharp drop in transmission efficiency, making it difficult to adapt to complex industrial conditions. Wired plug charging also faces long-term problems such as contact wear, sparking, corrosion, and manual supervision, and has significant safety shortcomings in scenarios such as chemical plants, mines, powder processing, and clean workshops. Based on magnetic coupling resonant technology, WIRELESSPT has created an industrial-grade magnetic coupling resonant wireless charging system, providing a high-fault tolerance, high-efficiency, and high-security non-contact power supply solution for various autonomous mobile equipment.

WIRELESSPT has been deeply involved in the field of industrial wireless charging for over a decade and is a national-level high-tech enterprise located in Qingdao High-tech Zone. Since 2014, it has focused on the research and development of radio frequency energy transmission technology. The entire magnetic coupling resonant wireless charging system has complete independent intellectual property rights. Different from ordinary induction schemes, it achieves energy transmission through resonant matching of the receiving and transmitting coils, relaxes positioning constraints, and supports larger transmission gaps and offset tolerance. Equipment can be stably charged without the need for millimeter-level precise docking, perfectly adapting to the automatic replenishment needs of various types of mobile equipment such as AGVs, AMR, inspection robots, humanoid robots, and RGV.

The system has excellent environmental adaptability. It adopts a fully sealed structure design, supports IP67 dustproof and waterproof, operates stably in a wide temperature range, and can withstand dust, oil, high humidity, and corrosion. For high-risk scenarios such as petrochemicals, powder processing, and mines, WIRELESSPT provides explosion-proof versions, which have dual explosion-proof qualifications for gases and dust, eliminating the risk of charging arc sparks and meeting the strict safety thresholds of project bidding. At the same time, it has an FOD (foreign object detection) function, which can real-time identify metal debris, iron filings, and other foreign objects in the charging area, eliminating the risk of overheating and fire from the source and strengthening the industrial charging safety defense line.

In terms of energy efficiency and scheduling, the WIRELESSPT magnetic coupling resonant wireless charging system can achieve a transmission efficiency of over 90%, supporting opportunistic charging modes. Robots can automatically replenish energy during process waiting and short stop intervals, without the need to leave their posts to go to the charging station, significantly improving equipment online rates and helping factories achieve 7×24-hour uninterrupted operations. The product power range is wide, covering from watt-level inspection robots to kilowatt-level heavy-load handling equipment. It also provides integrated and split hardware forms, with the controller and coil separated in the split solution, specifically addressing the renovation challenges of AGVs, shuttle vehicles, and internal space constraints in the body of the machine that make it difficult to install charging modules. New production lines and upgrade of existing equipment can be flexibly implemented.

The entire system is equipped with an intelligent charging management unit, which collects real-time voltage, current, and temperature data, supports connection with the upper-level scheduling system, automatically identifies battery types and adapts charging curves, is controllable in constant current and constant voltage, and protects the battery life. There are no exposed electrodes or mechanical friction losses, significantly reducing spare parts replacement, manual cleaning, and maintenance costs, and eliminating the long-term expenditures of repeated maintenance and replacement of contacts in wired charging.

Today, the WIRELESSPT magnetic coupling resonant wireless charging system has been implemented in dozens of industries such as chemical plants, power, semiconductor clean workshops, warehousing logistics, and mine inspections, serving numerous industrial automation equipment manufacturers and end factories. With the continuous expansion of the humanoid embodied intelligence and heavy-duty mobile robot markets, energy replenishment solutions have become a core indicator for equipment selection. WIRELESSPT will continuously iterate the magnetic coupling resonant wireless charging technology, providing a safe, stable and highly adaptable contactless power supply solution. This will enable more special scenarios and dark-light factories, and promote the true realization of industrial automation towards an unmanned closed-loop system.
