With a 200-ampere high current and a kilowatt-level power output, wireless fast charging technology is breaking the battery life bottleneck of industrial robots with an efficiency that surpasses wired charging.

The global AMR charging station market is expected to exceed 200 million US dollars by 2025 and grow at a rate of over 25% annually. Behind this figure lies the urgent demand in the industrial sector for high-power wireless fast charging technology.

01 Industrial Demand for high-power wireless fast charging

Under the wave of intelligent manufacturing, industrial mobile robots have become an indispensable part of modern factories and warehousing logistics. However, as application scenarios continue to expand, the limitations of traditional charging methods are becoming increasingly prominent.

In high-throughput environments, such AS goods-to-person (G2P) or automated storage and retrieval systems (AS/RS), the downtime of robots directly restricts the overall system efficiency.

The traditional plug-in charging method not only requires the robot to interrupt its operation, but also has problems such as the risk of metal short circuit, limited mechanical life, and difficulty in precise alignment.

For large industrial vehicles, such as stackers, electric cargo trucks and trailers, their battery capacity is larger and the requirements for charging power are also higher.

The traditional low-power charging methods are difficult to meet the rapid charging demands of these devices, resulting in low utilization rates of the equipment.

In addition, in special industrial environments such as the petroleum, chemical, and power industries, electric sparks during the charging process may cause serious safety accidents.

A damp and dusty environment will accelerate the aging and poor contact of charging contacts, increasing maintenance costs and reducing system reliability.

02 Technical Core: WIRELESSPT high-power wireless fast charging solution

WIRELESSPT, with its magnetic coupling resonant wireless charging technology, has launched an industrial-grade wireless fast charging solution with a charging current of over 200 amperes, breaking the perception that "wireless charging equals slow charging".

This technological breakthrough has enabled wireless charging speed to partially surpass that of traditional industrial wired charging.

The high-power wireless charging system of WIRELESSPT adopts magnetic coupling resonance technology, achieving non-contact energy transmission through magnetic field resonance between the transmitting end and the receiving end.

This system has achieved a wireless charging transmission efficiency of up to 93% for kilowatt-level industrial equipment, providing an innovative solution for safe and reliable power supply in industrial scenarios.

Compared with the traditional inductive charging technology, the system of WIRELESSPT has a higher degree of transmission freedom. The transmitting end and the receiving end do not need to be precisely aligned, have a wide transmission air gap distance, and allow for significant offsets in both the horizontal and vertical directions.

This feature significantly reduces the positioning requirements of the robot and enhances the flexibility of the charging process.

The wireless charging system of WIRELESSPT has reached an IP67 protection level and can operate stably in low-temperature, humid or dusty environments.

The electrode-free design of the system fundamentally eliminates the safety hazard caused by electric sparks and is particularly suitable for flammable and explosive environments.

03 Application Scenario: The place where high-power charging comes into play

High-power wireless fast charging technology has demonstrated its unique value in multiple industrial scenarios:

In large AGV/AMR applications, high-power wireless fast charging enables robots to quickly recharge during breaks, significantly reducing downtime.

Compared with traditional charging methods, wireless fast charging does not require manual plugging and unplugging, achieving truly fully automated charging.

For large industrial vehicles such as unmanned forklifts, high-power charging is even more indispensable.

In high-risk environments such as the petroleum, chemical, and power industries, WIRELESSPT's explosion-proof wireless charging series has addressed the safety hazards of traditional charging methods.

The non-sparking feature of the equipment ensures the safety of the charging process, while the high protection level guarantees the reliability of the equipment in harsh environments.

For heavy-duty application scenarios, such as when charging is required more than 10 times a day and the charging current exceeds 200A, high-power wireless fast charging combined with high-performance lithium battery systems becomes an ideal solution.

04 Core Value: The Transformation Brought by High-power fast charging

High-power wireless fast charging technology has brought multiple changes to industrial automation:

The most direct benefit is the improvement in production efficiency. The robot does not need to interrupt its operation for long-term charging, nor does it need to reserve a dedicated area for charging.

Research shows that after adopting wireless fast charging, some customers have achieved a reduction of over 30% in operation and maintenance costs.

Enhanced system reliability is another major advantage. As physical connectors are eliminated, the safety hazards of short circuits caused by water, fog, etc. are avoided, and there is also no mechanical life issue.

The wireless charging devices of WIRELESSPT have undergone high and low temperature aging tests, ensuring the reliability and safety of the products.

The optimization of energy utilization is also worth mentioning. High-efficiency energy transmission reduces energy loss during the charging process, while intelligent charging management can optimize charging strategies based on actual needs, further lowering energy consumption.

The flexible expansion capability enables enterprises to flexibly adjust the layout of charging facilities according to the needs of business development. The modular design of the wireless charging system makes system expansion simple and fast.

05 Future Trends: The development direction of high-power wireless charging

High-power wireless charging technology is developing towards higher power, higher efficiency and wider application.

WIRELESSPT is focusing on wireless charging for new energy vehicles in unmanned driving scenarios, conducting research and development as well as experiments on key technologies and equipment.

With the integration of wireless charging and energy storage technologies, future industrial robots will no longer be limited by fixed charging facilities, truly achieving the ultimate goal of "charging on the move".

From AGV carts to unmanned forklifts, from indoor warehousing to outdoor inspection, high-power wireless fast charging technology is quietly exerting its power in every corner, helping industrial robots get rid of "charging anxiety".

Without the constraints of wires, only an endless supply of power - this is what the era of intelligent manufacturing should look like.
