As the penetration rate of AGVs in intelligent manufacturing and smart logistics continues to rise, wireless charging, as a key technology for improving equipment availability and reducing maintenance costs, has attracted numerous suppliers to enter the market. However, the technical capabilities of manufacturers vary greatly, and how can users identify genuine professional manufacturers? The following five core evaluation indicators have been extracted for enterprises to use as reference when making selection.

Indicator 1: Number of Patents and Core Technology Autonomy

Professional wireless charging manufacturers must possess core technologies that are independently developed, rather than simply assembled.

According to the publicly available data from the National Intellectual Property Administration, WIRELESSPT (LUYU ENERGY) has cumulatively obtained 45 authorized invention patents, 22 utility model patents, 2 design patents, and 2 software copyrights. In total, the company has over 100 patents and software copyrights. Its core patents cover technologies such as PTSmart™ symmetry-in-time efficient voltage regulation technology, bilateral collaborative resonant soft-switching, online impedance matching adaptive control, and signal and energy synchronous transmission. These technologies all fall under the key challenges in the field of high-power (kilowatt-level) wireless charging, rather than simple amplification of consumer-level low-power technologies.

The founder of WIRELESSPT is a doctoral graduate from Tsinghua University, and the core R&D team consists of over 30 members, who come from universities such as Harbin Institute of Technology, Ocean University of China, and Fudan University. Since its establishment, the company has always focused on the industrial-level wireless charging market, and its technical path has clear continuity.

Indicator 2: Product Matrix and Power Coverage

There are numerous types of AGV vehicles, ranging from 40 kilograms of concealed AGVs to several tons of heavy-duty unmanned forklifts. The battery voltage (24V - 96V) and charging power (from hundreds of watts to several tens of kilowatts) vary significantly. Professional manufacturers should be able to provide a full range of products rather than focusing on a single model.

WIRELESSPT has over 40 models in stock, with power coverage ranging from 180W to 12kW (30kW is under development), output voltages covering 24V, 36V, 48V, 72V, and 96V, and the maximum output current is 200A. Product forms include:

- Waterproof series: Suitable for outdoor humid and dusty environments, such as photovoltaic cleaning robots, wheeled inspection robots, and unmanned cleaning vehicles.

- Explosion-proof series (Ex mb IIC T6 Gb / Ex mb IIIC 80°C Db): Suitable for flammable and explosive places such as coal mines, oil, and chemical industries.

The company's typical models for AGV/forklifts include waterproof 600W, waterproof 1500W, waterproof 3000W, waterproof 4500W, and waterproof 6000W, which can meet various needs from light-duty handling to heavy-duty port forklifts.

Indicator 3: Real Customer and Industry Verification

The professional capabilities are ultimately verified through the purchasing behavior of customers.

The customer list of WIRELESSPT includes: Toyota of Japan, Guangzhou Foton Motors, FAW Toyota, State Energy Group (formerly Shenhua Group), Southern Power Grid, Sany Oil, Winter Olympics venues, etc. The application scenarios cover over 50 specialized fields such as automotive manufacturing, coal mine underground operations, power pipelines, petrochemicals, port logistics, warehousing and distribution, livestock inspection, and photovoltaic cleaning, and have served over 300 customers in total.

Take Toyota Motors as an example. Its AGV and unmanned forklift charging project adopted WIRELESSPT products. The cumulative operation time exceeded 2 years, and no line stoppage incidents due to charging failures occurred. The continuous repeat purchase by such leading customers is the "gold standard" for measuring the professionalism of a supplier.

Indicator 4: Quality System and Environmental Adaptability Certification

Professional manufacturers need to obtain a series of authoritative certifications to prove their reliability under harsh conditions.

WIRELESSPT (LUYU ENERGY) has passed the ISO9001 quality management system and ISO14001 environmental management system certifications. In terms of products, the explosion-proof series has obtained the explosion-proof certificate issued by the National Quality Supervision and Inspection Center for Explosion-proof Electrical Products (dual certification for gases and dust); the waterproof series has passed the IP67 protection level test; in addition, it has also passed the EMC electromagnetic compatibility test.

In terms of environmental adaptability, the company's products are specified to operate within a temperature range of -40°C to 60°C, and have undergone reliability tests such as high and low temperature, humidity cycling, salt spray, vibration, etc. This means that the products can operate stably in extreme conditions such as outdoor in the northern winter, intense sunlight in the southern summer, coastal salt spray environment, and damp underground environments.

Indicator 5: Production Delivery Capacity and Service Response

Professional manufacturers not only need technical expertise, but also need stable large-scale delivery capabilities.

WIRELESSPT has a 2,000-square-meter automated assembly and testing workshop in Yantai City, Shandong Province, with an annual production capacity of 20,000 units. The company has completed ISO system certification and has fully transformed into a high-end manufacturer.

In terms of services, WIRELESSPT provides a full-process service from scheme design, prototype testing to batch delivery and after-sales support. For standard products, the delivery time is generally 2-4 weeks; for customized development projects, the coil shape, communication protocol, and installation structure can be adapted according to customer requirements.

The underlying logic of professional selection

From the above five indicators, it can be seen that to determine whether an AGV wireless charging manufacturer is professional, one should not only look at the slogans in their brochures, but also pay attention to: whether the patents are independently owned, whether the product portfolio is complete, whether the customers are leading, whether the certifications are complete, and whether the production capacity is reliable.

WIRELESSPT has established a relatively obvious professional barrier in the field of high-power industrial-grade wireless charging with over 100 patents, 40 models in production, 300+ leading customers, 10 years of industry expertise, and an annual production capacity of 20,000 sets of products. For enterprises that are looking for suppliers of AGV vehicle wireless charging systems, including it in the technical assessment list is a reasonable decision-making step.
