Chinese automaker BYD is making headlines after filing a new patent for an advanced robotic system that can charge electric vehicles (EVs) and inflate tires automatically without any human help. The patent, titled “A Robot,” went to China’s National Intellectual Property Administration (CNIPA) on March 24, 2025. It introduces a fully autonomous robot designed to handle both EV charging and tire inflation in one seamless process.
The BYD robot is designed to work fully on its own without human help. It can scan a parked vehicle, check its battery level, and measure tire pressure. After checking everything, the robot decides what the vehicle needs. It can then charge the battery or inflate the tires, or even do both tasks one after another. This makes the system very useful for everyday EV users who want a simple and easy experience.
The most important features of this BYD robot is that it does not need any changes in the vehicle. It works with existing EV charging ports, which means it can be used with most electric vehicles already on the road. This is a big advantage because it removes the need for extra hardware or costly upgrades. It also makes the technology easier to use in real-world situations.
The robot uses a smart system that includes different modules working together. These modules help the robot move, scan, connect, and complete its tasks with accuracy. When a car enters a special parking area, the robot starts scanning it. It checks the battery level and all four tires. If the battery is low, it starts charging, if the tire pressure is low, it inflates the tires. If both are needed, it completes the tasks step by step.
The system follows a closed-loop process. This means the robot checks each step before moving to the next one. It ensures the position is correct, secures the connection, and completes the task properly. This helps reduce errors and makes the process safe and reliable. Because of this system, the BYD robot can work without any human supervision.
This new technology is much needed as the demand for better EV charging solutions is growing fast. Many cities still face problems like limited charging stations and difficulty installing new chargers in old buildings. In such cases, a mobile robotic charging system can be very helpful. It does not need fixed infrastructure and can be used in different locations based on demand.
Other companies in China are working on similar technologies. Li Auto, in partnership with CGXi, has developed a robotic charging arm that can connect to a vehicle very quickly with high accuracy. Huawei has already deployed robotic charging systems in several cities. Zeekr and BMW are also testing their own automated charging solutions. However, BYD’s system stands out because it adds tire inflation along with charging, making it a complete service solution.
The market for robotic EV charging is growing rapidly. In 2024, China’s mobile charging robot market reached around 400 million CNY, equal to about 58 million dollars. Experts believe this number will increase a lot in the coming years as more people switch to electric vehicles. With over 20 million charging connectors already installed in China, the need for smarter and more flexible solutions is becoming more important.
Even though BYD has not shared any production timeline yet, the patent shows the company’s future direction. It suggests that the EV industry is moving toward fully automated systems where vehicles can take care of themselves without human help. This could save time, reduce effort, and improve convenience for users.
