The International Lunar Research Station, led by the China National Space Administration, aims to establish a research facility on the Moon, supported by multiple lunar robots, including exploration robots, multi-functional operation robots, and mission-specific robots for Chang'e-8. Ensuring a reliable power supply for these robots in the Moon’s harsh environment is a critical challenge. This study introduces a wireless charging bus system based on NearLink technology to address power supply and charging limitations. NearLink, a novel wireless communication and power transmission technology, provides high energy transmission efficiency, strong anti-interference, and low latency—essential for lunar missions. The system comprises four key modules: power transmission, power receiving, charging control, and power management. Energy is wirelessly transmitted from the power transmission module to the receiving module, which then charges the robot’s battery. The charging control module ensures efficient and safe charging, while the power management module guarantees stable system operation. Experiments and simulations validate the system’s high charging efficiency, stability, and performance under lunar conditions, with strong resistance to interference. This system offers an effective solution to the power and charging challenges of lunar robots, with broad potential applications for lunar and deep space exploration missions.
