Xiaomi built a robotic arm that plugs in your EV at home, delivering on a promise Tesla made in 2014 and never kept

Xiaomi has unveiled a robotic charging arm designed for residential garages that automatically plugs and unplugs an electric vehicle without any owner intervention. The system detects the vehicle’s position after parking, extends to the charging port, connects the cable, and retracts it once charging is complete or a preset battery level is reached. Xiaomi is targeting a Q4 2026 retail launch in China, though no price has been announced.

The concept is not new. In December 2014, Elon Musk tweeted that Tesla was working on a charger that “automatically moves out from the wall and connects like a solid metal snake.” Tesla demonstrated a functional prototype in August 2015, a multi-segmented robotic arm that located the charge port on a Model S and plugged itself in.

The product never shipped. Tesla has since pivoted to wireless charging, acquiring German startup Wiferion in 2023 and designing the Cybercab robotaxi without a physical charging port entirely. Xiaomi’s approach is more conventional but potentially more practical: a compact unit that works with existing plug-in standards rather than requiring new vehicle hardware.

The arm has a body width of just 152mm, narrow enough to mount alongside tight residential parking spaces. It uses AI-based vision recognition for what Xiaomi describes as sub-millimetre precision when inserting the plug. Owners can also initiate charging remotely via smartphone if the vehicle is parked within the arm’s reach.

The company emphasised that the promotional video was filmed in a real-world setting rather than a controlled environment, and that all demonstrated features are production-ready. That claim has not been independently verified, and Xiaomi has shipped more than 600,000 EVs in under two years, giving it the manufacturing scale to bring accessories like this to market. Whether a robotic charging arm appeals to enough buyers to justify production remains an open question, particularly without pricing.

The robotic arm is designed to integrate with Xiaomi’s broader smart home and automated parking ecosystem. The intended workflow pairs autonomous parking with autonomous charging: the car parks itself in the garage, the arm plugs in, and the owner walks away. That vision depends on vehicle-to-infrastructure communication protocols that Xiaomi controls end-to-end across its SU7 and YU7 lineup, an advantage of building both the car and the accessory.

Xiaomi is not the only Chinese company pursuing this technology. Huawei demonstrated a robotic charging arm for the Maextro S800 in January 2025 with full unmanned automation. Li Auto and its partner CGXi have developed a rail-based robotic charging system for public stations, with commercial deployment planned for Q2 2026 across Li Auto’s 5C fast-charging network. BYD has filed patents for an AI-powered charging robot that also handles tyre inflation.

The competitive landscape extends beyond plug-in robotics. Dutch startup Rocsys raised $13 million in April to scale its M1 overhead rail-mounted robotic charger for robotaxi depots, a commercial-fleet application rather than a consumer one. Porsche has taken a different path altogether with its 11kW wireless inductive charging pad for the Cayenne Electric, which transfers power through a magnetic field between a floor plate and a receiver under the vehicle. Porsche’s system launches in Europe in 2026.

The common thread is that multiple companies have concluded EV owners should not have to handle charging cables. The approaches differ, robotic arms for plug-in automation, wireless pads for cable elimination, overhead rails for fleet operations, but the underlying bet is the same: that convenience is a barrier to EV adoption and that the charging experience needs to become invisible.

For Xiaomi, the robotic arm also serves a strategic purpose beyond convenience. The company is targeting 550,000 vehicle deliveries in 2026 and has built its automotive brand on the promise that everything in a Xiaomi ecosystem, phone, home appliances, car, works together seamlessly. A robotic charging arm that only works with Xiaomi vehicles strengthens that lock-in. Whether the product reaches production at a price point that makes it more than a novelty will determine if it stays a concept video or becomes a real differentiator.
