In the evolution of intelligent factories and smart logistics, AGV/AMR/RGV have become the core carriers for enhancing efficiency. However, the charging process - whether it is manual insertion and removal, contact connection, or regular battery replacement - has always been the "last mile" bottleneck that restricts the all-day efficient operation of the fleets. WIRELESSPT has launched an integrated high-power wireless charging system, featuring an integrated design, high offset tolerance, and fast charging with large current, to create a truly "invisible" energy hub for AGV/AMR/RGV.

I. Integrated Design: Re-defining the Product Form of AGV Wireless Charging

Traditional wireless charging systems often adopt a separate structure of "box + coil", with the power converter and coupling coil being separated, resulting in large space occupation and relatively cumbersome installation. WIRELESSPT integrates the power converter and coupling coil into the same housing, achieving integrated packaging of electricity, magnetism, heat, and signal.

Four integrated advantages:

1. Volume reduced by approximately 60%: The flat packaging controls the thickness of the receiver, allowing it to be easily installed in the AGV vehicle body without occupying additional space.

2. Ready for installation: The transmitter and receiver are both single modules, and can be fixed on-site, significantly reducing deployment time.

3. Improved reliability: Without exposed cables and connectors, the number of failure points is significantly reduced, and it is suitable for high-frequency and long-term operation.

4. Cost optimization: Integrated production reduces material and assembly costs, providing customers with a more cost-effective option.

II. PTSmart™ Technology: Eliminating the Impact of Offset on Efficiency

One of the major drawbacks of wireless charging is that if the AGV's docking position is slightly off, the charging efficiency drops sharply. WIRELESSPT is based on the principle of parity-time symmetry, and the PTSmart™ wireless charging technology it employs can maintain the system's output power and efficiency relatively constant within the entire working range of the AGV (in the X, Y, and Z axes).

Take a 1500W product as an example. Within a horizontal offset range of ±50mm in the X-axis and ±10mm in the Y-axis, and within a vertical working distance range of 20-100mm, the charging efficiency remains above 87%. This means that the AGV does not need to be precisely aligned to meet the charging requirements, significantly reducing the difficulty and cost of system integration.

III. Taking the 1500W/3000W series as an example: High-power fast charging for AGV/RGV

WIRELESSPT is designed for AGV/RGV scenarios such as production line handling, warehousing logistics, and heavy-load transportation.

Key features:

- 50A high-current fast charging: Utilizing the fragmented time during AGV operations (such as loading/unloading goods, waiting for signals) to quickly replenish energy, truly achieving "stop-and-charging immediately".

- Intelligent charging management: Built-in constant current - constant voltage charging curve, automatically adapting to different types of batteries such as lithium batteries and lead-acid batteries, without the need for external charging circuits.

- Multiple safety protections: Over-temperature protection (automatic load reduction at 75℃), over-current and over-voltage protection, no-load startup protection, communication interruption protection, etc., ensuring the safety of the equipment and the battery.

- Wide temperature and voltage range: Adapted to extreme environments from cold storage warehouses (-40℃) to high-temperature workshops (+60℃).

IV. Typical Application Scenarios: Full Coverage of Production Lines, Warehousing, and Heavy Loads

Scenario One: AGV on Automotive Component Production Line

In the welding and assembly workshops, AGVs transport materials along fixed routes and stop briefly at multiple workstations. AGVs automatically recharge upon each stop. The problem of sliding contact line wear has been significantly alleviated, and the production line operation rate has significantly increased, with maintenance hours reduced by over 90%.

Scenario Two: Latent AMR in E-commerce Warehousing

In large distribution centers, dozens of AMRs simultaneously sort items. By distributing the transmitting ends in natural stopover points such as shelf areas and sorting platforms, AMVs utilize 15-30 seconds of fragmented fast charging during each stop. The daily charging frequency of each vehicle has increased from 1-2 times to tens of times without any noticeable interruptions, eliminating the charging queue phenomenon, and increasing the throughput of the fleet by 15-20%.

Scenario Three: Ring-shaped Line of Heavy Load RGV

In steel and building material raw material warehouses, heavy-load RGV transports bulk materials along the track. The wireless charging system is installed at the loading and unloading stopover positions, and it automatically charges during the several minutes of loading and unloading materials. The traction cable crushing faults have been eliminated, and the availability rate of RGV has increased from 87% to over 98%, significantly reducing the production losses caused by power supply issues.

V. WIRELESSPT: The Pioneering Provider of AGV Wireless Charging

WIRELESSPT was established in 2014 and is a national high-tech enterprise. Its core team comes from renowned universities such as Tsinghua University, Harbin Institute of Technology, and Ocean University of China. The company holds 45 authorized invention patents and has a 2,000-square-meter automated assembly and testing workshop, capable of producing 20,000 sets of robot wireless charging products annually.

The company has served over 100 well-known enterprises including China Shipbuilding, Weichai, and Southern Power Grid, and its products are widely used in AGV/AMR/RGV in fields such as automotive manufacturing, 3C electronics, pharmaceutical cold chain, and e-commerce warehousing.

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