In the evolution of intelligent factories and smart logistics, AGVs have become the core arteries that connect production, warehousing, and distribution. They shuttle between production lines day and night, precisely completing material handling, semi-finished product circulation, and finished product storage. However, behind the glamorous automation, a "contact-based" bottleneck always exists - the charging process relies on physical contact, which leads to wear and tear, sparks, maintenance, and failure, and a series of chain problems. WIRELESSPT has launched a full-power AGV wireless charging solution, using non-contact, high-freedom magnetic resonance technology, to completely restructure the energy replenishment method of AGVs, making "invisible charging" a standard capability of intelligent production lines.

I. "Contact Anxiety" in AGV Charging

As the scale of AGV fleets continues to expand, the problems with traditional charging methods have become increasingly prominent:

1. Wear and poor contact: Mechanical contacts such as brushes and pins quickly oxidize and accumulate dust in dusty and oily environments, resulting in a decrease in charging success rates and frequent "stalled" incidents of AGVs.

2. Safety risks from electric sparks: Instantaneous arcs occur when plugging or unplugging or when there is poor contact, posing risks in storage, chemical, textile, and other scenarios where flammable materials are present.

3. High maintenance costs: The lifespan of contacts is only tens of thousands of times, and frequent replacement of spare parts and manual cleaning result in annual maintenance costs ranging from tens of thousands to several hundred thousand yuan.

4. Impact on efficiency due to charging queues: With limited fixed charging points, multiple AGVs with low battery levels are forced to wait, reducing overall throughput.

These issues are referred to as "contact anxiety" - originally introduced to achieve automation, AGVs now rely on manual intervention and frequent maintenance due to the physical contact in the charging process.

II. WIRELESSPT Solution: The Leap from "Contact" to "Wireless"

The WIRELESSPT solution caters to the diverse application scenarios of AGVs and offers a 180W to 6000W full-power wireless charging system. With its core technology, it redefines AGV charging:

1. Integrated design, small size, easy installation

The power converter and coupling coil are integrated and packaged together. Compared with the separate solution, the volume is reduced by approximately 60%. The receiver is thin and can be easily embedded in the AGV body without occupying the cargo space. The transmitter is fixed on the ground and can be installed immediately without complex debugging.

2. Unique wireless charging technology, large offset tolerance

Based on the principle of parity-time symmetry, within the range of ±50mm on the X-axis, ±10mm on the Y-axis, and a vertical distance of 0-100mm, the charging efficiency remains above 87% (some models reach 93%). AGVs do not need high-precision docking, and the original navigation accuracy can meet the charging requirements, significantly reducing the difficulty of system integration.

3. High current fast charging, fragmental recharging

Supporting rated output currents of 50A/100A and above. Utilizing the short stopovers during AGV loading/unloading and waiting for signals (from tens of seconds to several minutes) for rapid recharging, enabling "stop and charge on the spot". The overall effective operation time of the fleet can be increased by 15-25%, eliminating the need for dedicated charging stops.

4. IP65/IP67 protection, adaptable to harsh environments

Fully sealed design, dust-proof, water-resistant splashing, corrosion-resistant. The working temperature covers -40℃ to 60℃, suitable for cold storage, high-temperature workshops, and outdoor extreme conditions.

5. Intelligent charging management, maintenance-free

Built-in constant current-constant voltage charging curve, automatically adapting to lithium batteries and lead-acid batteries. Supports shallow charging and shallow discharging, extending battery life by over 30%. Without mechanical contacts, no cleaning, replacement required, and maintenance cost approaches zero throughout the entire life cycle.

III. Full-power matrix, precisely matching various AGVs

The WIRELESSPT products have power coverage ranging from 180W to 6000W (expandable to 12kW/20kW), suitable for all scenarios from light-load inspection AGVs to heavy-load unmanned forklifts.

IV. Typical Application Scenarios

Scenario One: Automotive Assembly Line - Unobtrusive Battery Recharge at High Production Rates

In the welding and assembly workshops, AGVs deliver components along fixed routes, stopping briefly at multiple workstations. A 1500W transmitter is embedded in the ground at the stopover points, and the AGV automatically recharges itself upon each stop. The sliding contact lines/drag cables have been completely replaced, and the production line availability rate has increased to over 99%, with maintenance time reduced by 90%.

Scenario Two: E-commerce Warehousing - Hundreds of AMRs Do Not Queue

In large distribution centers, dozens of concealed AMRs simultaneously sort items. 3000W transmitting ends are distributedly deployed at natural stopover points such as shelf areas and sorting platforms. The AMV uses the 15-30 seconds of fragmented fast charging during each stop. The phenomenon of charging queues disappears, and the vehicle throughput increases by 15-20%.

Scenario Three: Chemical/Textile Workshops - Safety First

In environments with dust or flammable substances, traditional contact charging has high spark risks. The WIRELESSPT explosion-proof wireless charging series (Ex mb certification) achieves zero-spark charging and has been widely applied in multiple chemical enterprises.

V. WIRELESSPT: A Reliable Partner for AGV Wireless Charging

WIRELESSPT was established in 2014 and is a national high-tech enterprise. The company holds 45 authorized invention patents and has a total of over 100 patents. It has a 2,000-square-meter automated assembly and testing workshop and can produce 20,000 sets of products annually. It has served over 100 well-known enterprises such as China Shipbuilding, Weichai, and Southern Power Grid.

"The core of AGV wireless charging is not 'wireless', but 'unperceptible'." Our goal is to make charging completely disappear from the to-do list of operators - no alignment, no plugging and unplugging, no maintenance required. The AGV only knows 'I will always have power'."
