A robotaxi has no driver to plug it in. At the end of a shift, someone or something has to connect the car to power. This month's news put three answers side by side: staff plugging cars in by hand, robotic arms on a rail, and wireless pads in the floor. Each one changes how a depot is laid out, staffed and powered.
Option 1: Manual plug-in
This is the simplest approach. A technician walks the row and connects each car to a standard DC fast charger. It needs no special hardware, so it is the quickest way to get a site running.
The cost is labor. Every plug-in is a task, around the clock, and the headcount grows with the fleet. Manual charging also needs walking paths, lighting and safe zones in the layout.
Vehicle design matters too. Not a Tesla App reported on September 5, citing a reviewer who saw the vehicle in Austin, that the Tesla Cybercab has no onboard charger and does not support AC charging. It accepts only DC fast charging. A site built only for Level 2 would not serve it.
Option 2: Robotic arm on a rail
A robot finds the charge port and plugs in the standard connector, so the car needs no changes. Rocsys announced the M1 on April 29, 2026. One overhead rail unit serves multiple bays and works with mixed fleets and any charger type, according to the company. Rocsys says the M1 is in pilot deployment, with large-scale rollout set to begin in 2027, and that it raised a $13 million Series A extension. It also claims up to 75% productivity increase from existing staff.
The tradeoffs are physical. A rail needs overhead structure and a regular bay layout, and the cars have to park accurately. It still relies on conventional DC chargers underneath.
Option 3: Wireless pad
On October 12, Charging Robotics, a 51%-owned subsidiary of Clearmind (Nasdaq: CMND), launched an inductive charging platform for robotaxis and automated parking. The company says the system is designed to deliver up to 10 kW at up to 95% efficiency under specified operating conditions. S&P Global Mobility's coverage describes those as design targets. The platform uses a ground pad and an onboard receiver, starts and records sessions automatically, and uses AI scheduling to spread power across vehicles and cut peak demand.
No cable and no moving parts is an appealing idea for unattended depots. The open question is speed.
The speed question
Here is the arithmetic, which is ours and not the company's. A battery of about 70 kWh at 10 kW takes about 7 hours to fill from empty, before losses. At 95% efficiency, the grid has to supply a little more than that. A robotaxi that needs to be back on the road in 15 to 20 minutes needs a charger in the hundreds of kilowatts, not 10.
That does not make 10 kW useless. Overnight parking and long idle periods suit slower charging, and the company positions the product for automated parking and between-trip top-ups. But for fast turnarounds, high-power DC plug-in charging is still the workhorse. Wireless at 200 to 300 kW has not been announced by this company or, as far as we found, shown at scale.
What this means for a site
Whichever method an operator picks, three things drive the site plan.
- Power first. Charging load sets the electrical service, and utility upgrades can take a long time. Plan the service for the final charger count, not day one.
- Layout for hands-free later. Even if day one is manual, leave room for rails, pads and consistent bay spacing.
- Labor and safety. Manual charging needs people on site at all hours, so lighting, access and a safe walking route matter.
FAQ
Can a robotaxi charge wirelessly today? One company launched a platform on October 12 and describes its figures as design targets. Check each vendor's deployment status.
Which method is fastest? Plug-in DC fast charging. A 10 kW wireless pad is much slower per vehicle.
Do robotic chargers need special vehicles? Rocsys says the M1 works with mixed fleets and any charger type.
