On September 3, 2025, during the military parade ceremony, domestically produced quadruped robotic dogs made a stunning appearance, showcasing China's advanced level of intelligent equipment to the world with their exceptional reconnaissance, strike, and obstacle-clearing capabilities. Their agile movements and tactical coordination not only demonstrated outstanding performance in simulated combat environments but also reflected significant breakthroughs in China's highly mobile and intelligent individual support systems.

As intelligent quadruped robots are increasingly widely used in scenic area management, industrial inspections, emergency rescue, and even military applications, robotic dogs are gradually becoming key forces in enhancing operational efficiency and replacing humans in high-risk operations. However, power endurance remains a core bottleneck restricting their ability to perform long-duration, high-intensity tasks. As a leader in medium- and high-power magnetic resonance wireless power supply technology, Zone Charge has launched an efficient wireless charging solution specifically tailored for robotic dogs, providing a solid energy guarantee for the continuous operation and stable performance of such intelligent equipment.

Zone Charge Wireless Charging Solution for Robotic Dogs

Zone Charge's wireless charging solution for robotic dogs is based on advanced magnetic resonance wireless power supply technology, offering standard wireless charging modules that are adaptable to various models and scenario requirements. The detailed description of the solution is as follows:

Receiver and Transmitter Installation: The receiver is installed under the abdomen of the robotic dog, a design that facilitates wireless alignment with the ground-based transmitter. The transmitter is fixed on the ground, forming a stable charging area. When the robotic dog's battery level falls below a certain threshold, it automatically returns to this charging area for recharging.

Non-Contact Charging Mechanism: Alignment and Charging: Once the receiving coil on the robotic dog's abdomen aligns with the ground-based transmitting coil, charging begins without the need for physical contact, with a charging distance of 2-5 cm. This non-contact charging method enhances convenience and flexibility.

Efficient Energy Transmission: Utilizing magnetic resonance technology, the charging efficiency reaches up to 87%, effectively reducing the charging time for robotic dogs and improving operational continuity.

IP67 Water and Dust Resistance: The modules feature excellent sealing performance, adapting to harsh environments such as outdoors, humidity, and dust, ensuring safe and stable operation of the equipment.

Intelligent Charging Management: Supports the 485 communication protocol, enabling collaboration with the battery management system to monitor battery status in real time, intelligently adjust charging strategies, and effectively prevent overcharging and over-discharging, thereby extending battery life.

For robotic dogs operating in hazardous areas such as flammable or explosive environments, Zone Charge has specifically launched explosion-proof wireless charging modules, including power levels of 300W, 600W, and 1200W, to meet charging needs in different scenarios. These explosion-proof modules not only offer efficient energy transmission capabilities but also strictly adhere to explosion-proof safety standards, ensuring the safety of the charging process and providing reliable support for the continuous operation of robotic dogs in hazardous environments.

Transformations Brought by Wireless Charging to the Industry

Zone Charge's wireless charging technology not only addresses the endurance challenges of robotic dogs but also injects new momentum into the entire intelligent robotics industry:

Enhance Operational Efficiency: Robotic dogs can achieve "charge while in use," reducing manual intervention and time spent returning to stations for charging, significantly improving task completion efficiency.

Reduce Operational and Maintenance Costs: Avoid failures caused by plug wear, poor contact, or water ingress, reducing maintenance frequency and costs.

Enhance Safety Performance: No exposed interfaces, eliminating risks of electric sparks and short circuits, making it particularly suitable for flammable, explosive, or humid environments.Drive Technological Iteration: Provide new power supply ideas for medium and large mobile robots, promoting the industry's continuous evolution toward automation and intelligence.

Leveraging its technical expertise and innovation capabilities in the wireless power supply field, Zone Charge provides reliable and efficient wireless charging solutions for robotic dogs and other intelligent robots. In the future, as application scenarios for intelligent equipment continue to expand, Zone Charge will further deepen technological research and development, driving the industry toward a smarter, more efficient, and safer new stage.
