A viral video circulating on social media has shown how China is using overhead robotic chargers to supply power to electric vehicles . The innovative solution has been deployed across various garages nationwide, reducing the burden on drivers of finding empty charging slots.
The system in question converts a parking space into a charging hub without installing individual chargers. The video was shared on social media platform X on February 20.Decoding how the system works✨🇨🇳China's overhead mobile charging stations support on-demand park-and-charge. Their automatic moving design eliminates the need for drivers to wait in line for charging. pic.twitter.com/3gCSArzvlC— 🇨🇳XuZhenqing徐祯卿 February 20, 2026The system operates through a ceiling-mounted robotic charger that moves along an overhead rail installed in parking garages. Acting as both a power conduit and mobility track, the rail allows the unit to travel to any parking space it serves.Drivers can request charging via a WeChat mini-program or QR code, prompting the robot to navigate to the vehicle, identify the charging port using cameras and sensors, and automatically connect the plug.Developers say the approach significantly reduces infrastructure costs. Instead of installing individual chargers at every parking spot, a single rail can power an entire row of vehicles from a single connection point.The trade-off is charging speed. Because the system relies on Level 2 AC power delivered through the rail, it cannot match the performance of dedicated DC fast chargers.However, for locations where cars remain parked for extended periods, such as offices, shopping centers, or residential complexes, the slower charging rate is considered sufficient.Architects of the systemSeveral Chinese brands are already working on commercializing this solution. LiAuto and CGXi have developed the ‘world’s first’ rail-based unmanned robotic charging arm.This arm moves along a sled style rail, integrated with sensor arrays and vision systems. These systems identify the charging point location and orientation on any vehicle.Wave Charging is another startup that uses a system called HAVA Robot. The robot uses an 18-degree-of-freedom flexible robotic arm riding on an H-shaped overhead track. According to the company, a single unit can serve eight or more parking spaces.Ground-based charging robots are also gaining momentum, with companies such as CATL subsidiary CharGo, NaaS Technology, GGSN, and VMR accelerating deployments. CharGo’s chief executive has projected that robotic systems could charge up to 20 percent of new energy vehicles by 2030.In Beijing, authorities plan to roll out 1,000 mobile charging robots across roughly 150 parking facilities, signaling growing institutional support for automated charging infrastructure.Not limited to ChinaChina isn’t the only country working on this solution. In the US, Westfalia Technologies introduced its WEPLUG system in May 2025, a 50 kW DC overhead gantry charger designed for automated parking facilities, fleet depots, and corporate campuses.The system uses a vision-guided robotic arm that lowers a connector into an adapter inserted by the driver, enabling multiple parking spaces. Other space-saving ideas are emerging as well.New York City’s Voltpost Air moves charging hardware off the ground, reducing clutter on crowded streets. However, none of the Western deployments is smaller in scale than the rapid rollout of robotic charging infrastructure underway in China.
