In harsh scenarios such as high-voltage substations, underground cable tunnels, and extremely cold transmission lines, power inspection robots are the "silent sentries" ensuring the safety of the power grid. However, problems such as spark hazards, interface corrosion, and low-temperature failure caused by traditional plug-and-pull charging have made the "battery life anxiety" of robots a fatal shortcoming restricting intelligent inspection. Qingdao WIRELESSPT Technology, with its military-grade wireless charging technology, has launched the world's first wireless charging solution for power inspection robots that is suitable for extreme environments. With three core advantages: IP68 water resistance, explosion-proof certification, and spark-free design, it redefines the energy supply security standards in high-risk scenarios.

The tragedy of charging in high-risk scenarios: Every plugging and unplugging is a risk

In special fields such as power, petrochemicals, and mining, robot charging faces three "death challenges" :

High-voltage electromagnetic interference: Exposed interfaces are prone to arc discharge in a strong electric field, which can cause equipment damage at the least and trigger an explosion at the worst.

2. High humidity and corrosion: The humidity in coastal substations and underground pipe galleries exceeds 90%, the rusting rate of metal contacts reaches 37%, and charging failures occur frequently.

3. Extreme cold and temperature difference: At -40℃, battery activity drops sharply, traditional charging piles start late, and charging efficiency plummets by 50%.

What is more serious is that manual plugging and unplugging for charging forces robots to frequently return to fixed stations, with a daily effective inspection time of less than six hours. Moreover, the intervention of personnel in high-risk areas itself is a major safety hazard.

WIRELESSPT Wireless Charging Solution: Fearless of Water and Fire, the "All-purpose Charging Station" in Extreme Scenarios

After five years of research and development, WIRELESSPT has deeply integrated magnetic resonance wireless transmission technology with military protection standards to create a fully enclosed, zero-contact, and self-adaptive charging system for extreme environments.

IP68 waterproof, dustproof and explosion-proof certification: Fearless of high pressure and high humidity, the "steel body"

The charging pile and the receiving end adopt an integrated cast shell, with vacuum potting inside to completely isolate water vapor, dust and corrosive gases. Even when fully immersed in water to a depth of 1 meter, it can still operate normally.

It has passed ATEX and IECEx explosion-proof certifications. There is no flammable paint or plastic material inside, which avoids static electricity accumulation. It is suitable for Class I explosive environments such as oil and gas pipelines and chemical storage.

2. Spark-free design: Eliminates the risk of ignition from the root

It adopts non-contact energy transmission, with no metal exposure throughout the charging process, avoiding the arc discharge problem in high-voltage electromagnetic fields.

It is equipped with an intelligent power regulation module. When an abnormal external magnetic field or equipment displacement is detected, the power supply will be cut off within 1 millisecond to ensure zero spark and zero radiation during the charging process.

3. Wide temperature range operation from -40℃ to 85℃ : No power interruption in extremely cold or hot weather

Equipped with self-heating battery pre-activation technology, it automatically heats up to the optimal charging temperature in an extremely cold environment of -40℃, and the charging efficiency is increased to 85% of the normal temperature state.

The heat dissipation system adopts aerospace-grade phase change materials, ensuring continuous full-power output without frequency reduction at a temperature of 85℃, making it suitable for extreme temperature difference scenarios such as deserts and steel mills.

Practical Evidence: How Does Wireless Charging Rewrite Industry Safety Records

- Southern Ultra-High Voltage Converter Station: 12 sets of WIRELESSPT wireless charging piles were deployed in an 800kV strong electromagnetic interference environment. The average daily inspection mileage of the robot was increased to 22 kilometers, and there was no electromagnetic abnormal alarm during the charging process.

- Bohai Bay Offshore Oil and Gas Platform: In a corrosive environment with salt spray concentration exceeding 3mg/m³, the charging piles have been operating continuously for 18 months without rust, and the frequency of robots returning to the station for charging has decreased by 70%.

- Qinghai-Tibet Plateau power Transmission Lines: In the extremely cold of -35℃, robots automatically replenish power during inspection intervals, extending the single charge life to 48 hours, and the winter inspection coverage rate has jumped from 58% to 95%.
