Cybercab Charging Depot Design: Layout, Wireless Charging Pads, Power, and Throughput
A Cybercab charging depot is designed around three facts: the vehicle has no charge port and charges from a ground pad at roughly 25 kW, it drives itself into and out of every stall, and it must be cleaned and re-dispatched with no one on site. That pushes the layout toward pull-through stalls with a pad centered in each, one-way circulation, a separate cleaning and inspection lane, and a power plant sized for pads in bulk plus a smaller bank of DC fast chargers for quick turns. Tesla's own Austin hub, filed in August 2026, pairs about 80 wireless stalls with 48 V4 charger posts — a useful template. Wins Parking designs these depots for property owners and delivers the power and site work behind them.
The Design Brief a Cybercab Sets
Tesla unveiled the Cybercab in October 2024 as a two-seat vehicle with no steering wheel, no pedals, and no charge port; it charges only by induction from a pad in the ground. Tesla demonstrated the system at about 25 kW and claimed efficiency above 90 percent (InsideEVs, October 2024). In February 2026 the FCC granted Tesla a waiver to use ultra-wideband radio between the car and the pad for centimeter-level alignment (electrive, February 21, 2026), and Tesla has since published two patents describing a dual-voltage pad and its foreign-object and living-object safety sensing (EVwire, August 17, 2026). Series production began at Giga Texas in April 2026, following the first unit on February 18, and public Cybercab rides opened in Austin on September 3, 2026 under an initial Texas authorization of 45 vehicles (electrive, September 4, 2026). The reference depot is Tesla's leased site on St Elmo Road in Austin, where permit filings reported by Tesla Oracle describe roughly 80 wireless charging stalls alongside 48 V4 Supercharger posts. Three design consequences follow. First, every Cybercab stall is a charging stall — the pad is the parking position. Second, because the vehicle self-parks, stall geometry can be tighter than human-driven parking but must be pull-through to avoid reversing maneuvers that slow dispatch. Third, at 25 kW the charging window is long, so a depot needs many pads rather than a few high-power plugs, and the electrical design is about breadth of distribution rather than a handful of 350 kW cabinets.
Cybercab depots for property ownersRobotaxi depot EV charger installation costStall Geometry for Driverless Pull-Through
Driverless fleets favor one-way, pull-through rows: a vehicle enters a stall from the aisle on one side, charges, and exits forward into the aisle on the other side. This removes the three-point turns and backing that take time and create conflict points. Stall width can drop toward 8 feet 6 inches for a compact two-seater with precise positioning, but designers should hold a standard 9-foot width where technicians will walk between vehicles or where a mixed fleet including Model Ys may use the same rows. Stall length should accommodate the vehicle plus a stopping tolerance in front of the pad and any wheel stop or sensor target. Aisle widths for one-way pull-through rows can be narrower than two-way retail aisles, but keep enough room for a tow vehicle and for a cleaning cart to pass. Angle the rows if the parcel shape is irregular; a 60-degree pull-through module often fits more pads on a constrained site than 90-degree rows with a wide aisle. Plan the pad position, not just the stall. The receiver coil sits under the vehicle, so the pad must be centered where the car will actually stop, with the approach path clear of speed bumps or drainage grates that could confuse alignment. Coordinate the concrete pour, the conduit stub-up, and the pad recess as one detail on the drawings, and mark stall targets that survive resurfacing.
Leasing land for a robotaxi depotRobotaxi depot revenue modelCharging Mix: Inductive Pads Plus DC Fast Chargers
A pad-only depot is efficient for overnight and midday top-ups but slow for a vehicle that needs a fast turn at peak. Tesla's Austin template — about 80 pads and 48 V4 posts — shows the intended split: most stalls charge slowly and continuously while a smaller bank of DC fast chargers handles quick turns for the Model Y portion of the fleet and any Cybercab variant that gains a port. Design for both. Size the split from dispatch modeling. If the fleet's busiest window sends 30 percent of vehicles out within an hour, the DC bank needs to turn that many cars in the preceding hour, while the pad field handles the rest over four to eight hours. A rule of thumb for early planning is one DC fast position per six to ten pads, then refine with the operator's trip data. Keep the fast bank close to the exit so charged vehicles leave without threading through the pad rows. Reserve conduit and pad space for the pad count to grow. Fleets step up in authorizations — Texas approved 45 Cybercabs at launch — so a site that opens with 40 pads and conduit to 120 positions can add capacity without trenching through an operating depot.
Robotaxi depot design & operationsAutonomous vehicle parking designSizing the Power Plant
Start with connected load, then apply a realistic diversity factor. Eighty pads at 25 kW is 2 MW connected; forty-eight DC fast posts at even 150 kW is 7.2 MW connected. Real coincident demand is much lower because charging is managed and vehicles arrive over time, but the utility service must still be sized for the peak your energy management system will allow. Depots of this scale typically land in the several-megawatt range and require medium-voltage service with one or more customer-owned or utility-owned transformers. Electrical infrastructure — conduit, conductor, panels, switchgear, transformers, and any utility upgrade — runs 30 to 60 percent of total project cost at DC fast-charging sites in NREL deployment data, and it is also the schedule driver: planning guidance for fleet depots puts utility service upgrades at 6 to 18 months from application (Joint Charging fleet depot guide, July 2026). File the utility application at letter-of-intent stage and design the electrical yard with room for a second transformer. Design for demand-charge control from day one. Commercial demand charges in the United States commonly run $8 to $22 per kW per month, and at low-utilization DC sites they can dominate operating cost. A depot energy management system that staggers pad charging, caps the DC bank during peaks, and optionally draws from a battery buffer protects the operating margin whether the owner or the tenant pays the bill.
EV charging design servicesEV charger installationCleaning, Inspection, and Staging Lanes
A robotaxi returns dirty. Every design needs a cleaning process that does not block charging rows: a dedicated lane or bay where interiors are vacuumed, sensors and cameras are wiped, and exteriors are rinsed. Tesla has patented automated cleaning concepts for the Cybercab, but early depots still rely on people and carts, so give the lane cover, lighting, water, power, and washwater capture that satisfies stormwater rules. Add an inspection and hold area sized for a few percent of the fleet: vehicles flagged by diagnostics, tire issues, or damage wait there for a technician instead of occupying a pad. Locate it near the operations building and the service entrance so parts and tools are close. Staging is where charged, clean vehicles queue for dispatch. In a well-designed depot the pad stalls themselves are the staging queue — vehicles remain on the pad until dispatched — but a short ready lane near the exit gate smooths surges. Keep entrance and exit gates separate, with queue length inside the fence so arriving vehicles never stack onto the public street.
Robotaxi depot managementParking lot dimensions & layout standardsSite Circulation, Gates, and Security
Circulation should be one-way and loop-free where possible: entry gate, cleaning lane, charging rows, ready lane, exit gate. A driverless vehicle follows its map; the designer's job is to give it a map with no ambiguous merges or dead ends. Make turning radii generous at row ends and keep pedestrian routes for technicians separated with striping or bollards. Gates should be automated and integrated with the fleet's dispatch system so vehicles open them on approach. Provide a manual override, a visitor and delivery entrance separate from fleet flow, and clear sightlines from the operations building. Perimeter fencing, controlled lighting with downcast fixtures, and camera coverage protect vehicles and satisfy insurers and neighbors. Include a small operations building or modular unit with a fleet-response desk, restroom, parts storage, and a tool bay, with a covered technician bay if the operator will do tire and light maintenance on site. Provide power and network for remote-assistance connectivity; every operator runs a command center that may need to intervene, and the depot must never be a dead zone.

Converting part of a garage into a Cybercab depot is possible, with caveats. Ground floors with direct street access, adequate ceiling height for sensor masts, and proximity to the electrical room are the practical zone; upper floors add ramp time, vertical circulation risk for driverless vehicles, and conduit routing through post-tensioned slabs. Inductive pads need a recess or a surface-mount detail approved by the structural engineer. Ventilation, fire code for charging, and floor loading for any battery buffer or transformer all need review. Where a garage cannot support the full charging plant, use it as a downtown staging annex — clean, hold, and dispatch — while the primary charging happens at a surface depot near the utility feeder. Mixed-use garages can also monetize off-peak floors: robotaxi staging overnight when public demand is low, public parking by day. The design challenge is separating fleet circulation from the public with gates and lane assignments that the vehicles' maps and the building's access controls both understand.
Start a depot designPhasing the Buildout to the Fleet Ramp
Operators grow in steps set by regulators and vehicle supply. Tesla's Austin Cybercab launch began with 45 authorized vehicles; Waymo's Miami depot operated from an interim 62-space site while its main airport-area facility was under construction in September 2026 (The Road to Autonomy, September 11, 2026). A depot design should therefore define a phase one that is fully functional at small scale — power, cleaning lane, first pad rows, gates — and later phases that add pad rows and DC positions without disrupting operations. Front-load the shared infrastructure: the utility service, the main switchgear, the trunk conduit routes, drainage, fencing, and the operations building. Those items are hard to add later and cheap to oversize now. Pads, DC cabinets, and lighting for later rows can follow the fleet. Tie phases to lease and rent milestones so the owner's capital and the operator's commitments move together. A phased concept plan is also the most persuasive document you can hand an operator's site team, because it shows them a depot that grows with their authorization rather than a fixed facility they must fill.
Design Deliverables Owners Should Expect
A complete Cybercab depot design package includes a site plan with stall and pad geometry, circulation and gate plan, cleaning and staging layout, an electrical single-line diagram with service and transformer sizing, a utility coordination log, a demand and energy model with the planned management strategy, a phasing plan, a stormwater and lighting plan, and an opinion of probable cost by phase. It should also include the operator-facing summary: a two-page site brief with location, power, capacity by phase, and timeline that a real estate team can circulate internally. That brief, not the drawing set, is what gets a depot onto an operator's shortlist. Wins Parking produces this package for property owners and then carries it into construction and operations, which keeps the pad detail, the conduit route, and the dispatch flow consistent from concept to opening day.
Step-by-step: designing the depot
The design sequence below runs from the operator's program to a construction-ready package. 1. Capture the operator's program: Fleet size by phase, vehicle mix (Cybercab and plug-in), peak dispatch windows, cleaning standards, on-site maintenance scope, and connectivity requirements. 2. Model charging demand: Translate the dispatch pattern into pad hours and DC fast sessions per day, then set the pad count, DC position count, and the peak demand the energy management system will allow. 3. Confirm utility service: Apply for service at the modeled peak with expansion headroom, confirm transformer ownership and location, and log the utility's lead time into the project schedule. 4. Lay out circulation and stalls: Design one-way pull-through rows with pads centered in each stall, a cleaning lane on arrival, a ready lane at the exit, separate gates, and technician paths. 5. Design the electrical distribution: Prepare the single-line diagram, size feeders and switchgear, route trunk conduit for full build, and detail pad recesses and DC foundations. 6. Add support facilities: Operations building, inspection and hold area, technician bay, lighting, cameras, fencing, stormwater controls, and washwater capture. 7. Package by phase: Produce the phased site plan, cost opinion, schedule, and a two-page operator brief that summarizes location, power, capacity, and timeline.

"Design the trunk conduit for three times the pads you open with. Trenching through a live robotaxi depot to add capacity is the most expensive mistake an owner can make, and it is entirely avoidable on the first drawing." — Ross Blankenship, Founder & CEO, Wins Parking. Tesla's positioning system uses pulse ultra-wideband radio between a transceiver in the vehicle and one on the ground-level charging station so the car can achieve optimal alignment for wireless charging — signals occur only briefly as the vehicle approaches the pad. — Paraphrase of the FCC waiver documentation for Tesla's inductive charging positioning system, as reported by electrive.
About Wins Parkingelectrive: Cybercab clears key regulatory step for inductive chargingHow does the Tesla Cybercab charge?
Inductively. The Cybercab has no charge port; a receiver coil under the vehicle pairs with a pad embedded in the ground. Tesla has demonstrated charging at about 25 kW with claimed efficiency above 90 percent, and in February 2026 the FCC granted Tesla a waiver to use ultra-wideband radio to align the vehicle over the pad. Tesla has also published patents covering a dual-voltage pad and its safety sensing.
How many charging pads does a Cybercab depot need?
Roughly one pad per vehicle that will be on site at the peak charging window, because at 25 kW each vehicle occupies a pad for hours. Tesla's Austin hub filings describe about 80 wireless stalls plus 48 V4 charger posts. Early planning can assume one DC fast position per six to ten pads, refined with the operator's dispatch data.
What stall dimensions work for driverless pull-through charging?
Pull-through stalls in one-way rows, typically 9 feet wide where technicians walk between vehicles and slightly narrower where only compact two-seaters with precise positioning will park. Length must include the vehicle plus stopping tolerance around the pad. Angled 60-degree pull-through modules often fit more pads on irregular parcels than 90-degree rows.
How much electrical service does a Cybercab depot require?
Connected load is large — 80 pads at 25 kW is 2 MW and 48 DC fast posts at 150 kW is 7.2 MW — but managed charging keeps coincident demand well below that. Depots of this size typically need several megawatts of medium-voltage service with one or more transformers, and utility upgrades commonly take 6 to 18 months from application.
Should a robotaxi depot have DC fast chargers as well as wireless pads?
Yes, in most cases. Pads handle slow, continuous charging for the bulk of the fleet; a smaller bank of DC fast chargers turns vehicles quickly at peak and serves plug-in vehicles such as Model Ys in the same fleet. Tesla's Austin template pairs about 80 pads with 48 V4 posts, which is a reasonable starting ratio to refine with trip data.
How do you control demand charges at a charging depot?
With an energy management system that staggers pad charging, caps the DC bank during utility peak windows, and optionally draws on a battery buffer. Commercial demand charges commonly run $8 to $22 per kW per month and can dominate operating costs at low-utilization DC sites, so the control strategy should be part of the electrical design rather than an afterthought.
Where does cleaning happen in a robotaxi depot?
In a dedicated lane or bay separate from the charging rows, with cover, lighting, water, power, and washwater capture. Vehicles are cleaned on arrival before they enter a pad stall, so the charging rows never wait on a cleaning crew. An inspection and hold area near the operations building handles flagged vehicles.
Can a parking garage be designed as a Cybercab charging depot?
Ground floors near the electrical room with direct street access can host pads and lower-power charging; upper floors add ramp time and conduit-routing cost through post-tensioned slabs. Many garages work better as downtown staging annexes — clean, hold, dispatch — paired with a surface depot near the utility feeder for the main charging plant.
How should a depot be phased?
Build shared infrastructure first — utility service, main switchgear, trunk conduit, drainage, fencing, cleaning lane, operations building — and open with the first pad rows sized to the operator's initial authorization. Add pad rows and DC positions in later phases without disrupting operations, and tie each phase to lease and rent milestones.
