Car onto the plate, connector into the port, confirm on the app. That is the last human contact with the vehicle until they come back for it.

Fig. 1 — Transfer cabin, sectionNTS
In an automated car park a steel plate carries the vehicle — through a lift, along a shuttle, into a rack nobody can walk into. We put the receiver on the plate and the transmitter in the floor. The plate draws power from whatever bay it happens to be standing in, across 42 mm of air. The only cable in the whole system is the short one from the plate to your car, and it goes wherever the car goes.
Sheet A-01b — Photography
Shot list · to be commissioned
Three photographs carry this site.
Not stock. Stock EV photography is a man smiling at a cable, and this product has no man and no cable. These are the three frames that only Charging Robotics can supply — shot at a live site, annotated over the top in the drawing language.
Frame 01 — Hero
Wide, low, inside the rack. A real car sitting on a real plate, floor unit visible beneath. Available light, long exposure, no people. Annotation overlays TX / RX / gap.
Replaces the hero drawing once shot. The drawing stays as the overlay.
Frame 02 — Detail
Macro of the gap. Plate underside and floor unit face, raking light across both, 42 mm of air between them. Shot on a tripod at bay level.
The dark inversion sheet. Photograph behind, dimension lines on top.
Frame 03 — Scale
The rack from the transfer cabin looking in. Depth, repetition, steel. One bay lit red. This is the image that makes a developer understand the scale of the problem.
As-built. Also the social and deck cover image.
Note — half a day with an architectural photographer at a live site covers all three, plus the plate and floor-unit product shots you will need for the deck.

Now nothing is plugged into the building.
The plate leaves grade carrying its own connector. There is no trailing cable behind it, no reel paying out, no contact rail to ride.
Lateral transfer into an assigned bay.
The rack decides where the car goes, not the driver. Placement lands within roughly ±100 mm of nominal — which the coil geometry is designed to absorb.
The floor hands it 10 kW.
Pad and plate identify each other, agree on limits, and the field comes up. 95% efficiency across 42 mm of air, into a cable the car is already holding.

No contact.
Nothing to wear out.
The transmitter is cast into the bay floor and never moves. The receiver rides under the steel plate. Between them: air. No brush, no reel, no trailing cable, no connector cycling twenty times a day on a machine expected to run for thirty years.
That is the whole argument. The efficiency, the load management, the app — all of it follows from the power path having no moving parts in it.

Methods of powering a moving plate
Five ways to power a moving plate. Four of them wear out.
Getting electricity to a car in an automated rack is not a charging problem. It is a problem of feeding a machine that never stops moving — which is a problem materials handling solved decades ago, badly.
MethodMoving parts in the power pathWhat failsVerdict

02Motorised cable reelReel, slip ring, cableSlip-ring wear and contact resistance drift; reel jams; cable abrasion measured in thousands of cycles, not years.Rejected
03Busbar + brush contactsSliding brushes on a live railBrush wear and carbon dust in an enclosed structure; arcing; exposed conductors in a space that also holds people during maintenance.Rejected
04Battery on the plateConnectors, plus a second battery per plateMass added to every plate the structure must lift; the plate battery now has its own charging problem; degradation on a fleet you can't easily service.Rejected

Uptime · safety · service
A pilot is a demo. An SLA is a business.
Wireless power in a car park is not judged on peak efficiency. It is judged on whether the bay works on a Tuesday morning in year three, and on whether a safety engineer will sign the drawing.
Uptime
95%
System uptime, contracted. Measured per site, not averaged across the fleet.
Response
24h
SLA response time on a fault, with remote diagnosis from the session record first.
Safety
Signed
Independent EMF and safety review per site before any unit is energised. No approval, no deployment.
Service
OTA
Firmware on both TX and RX updates over the air. No truck roll to patch a coil controller.
Why this is on the page — the first question a parking operator asks about inductive power is whether it is safe to stand next to. Answering it before they ask, with an independent signature rather than a claim, removes the objection that otherwise kills the meeting.

Every floor unit and every plate is a registered object.
A TX is bound to a bay forever. An RX is bound to whichever TX it is standing over right now — or to nothing, which the console calls Unassigned. Accounts sit above that, so each operator runs its own tenancy without seeing anyone else's network.

Here is a session that failed.
Twenty-nine minutes, 2.621 kWh delivered, then a hardware interrupt. We are showing it because every other page in this category shows a happy path, and a happy path proves nothing. What this proves is that the system is instrumented down to the coil: voltage, current, temperature, state of charge, and firmware on both halves of the pair, sampled through the whole session and kept.

Note — the marketing figure is 10 kW rated. The measured average across this session is 5.25 kW, with peak RX current at 40 A. Worth deciding which number the site leads with before this goes live; the rated figure is defensible, but a developer who later sees the console will notice the gap.
