One-to-one charging means one transmitter primarily serves one receiver at a time — the classic AGV dock. One-to-many means one transmitter (or a coordinated array) can energize multiple receivers, or a surface can charge whichever device lands in a zone.

01One-to-one

Predictable power budget and thermal design.
Straightforward authentication and billing/telemetry per vehicle.
Natural fit for high-power industrial docks (hundreds of watts to kilowatts).

02One-to-many

Convenient for desktops and multi-device consumer pads.
Requires load sharing, selective activation, and stronger FOD strategies.
Efficiency per device can drop if the field is spread or mistuned.
Industrial “many” often means many docks on a network — not one coil feeding many robots at once.

03SiCore-oriented view

High-availability robot fleets usually scale with many one-to-one docks plus cloud or local charge scheduling, rather than a single shared field. Multi-coil arrays still matter for alignment tolerance on one vehicle, which is different from truly simultaneous multi-vehicle charging on one pad.
