Wireless charging is much better for the use case for autonomous charging than the robot chargers... it’s equally efficient with no moving parts, less prone to failure.

Qualcomm Halo is able to transmit about 3.5KW. They once got up to 20KW in a demo. The technology has been sold off to WiTricity. Tesla's biggest Supercharger model transfers around 250KW. Although Qualcomm has been announcing that technology since 2013, there seem to be no non-demo installations.

“A partnership between Cabonline, Jaguar, Momentum Dynamics, and Fortam Recharge are launching a wireless charging taxi fleet in Oslo, Norway. The fleet consists of 25 Jaguar I-Pace SUVs equipped with inductive charging pads rated at 50-75 kW. The pads use resonant inductive coupling operating at 85 Hz to improve wireless charging efficiency and range.” [1] https://spectrum.ieee.org/cars-that-think/transportation/adv...

"Are launching". "Will be". No follow up on how it worked, a year later.

There's no way that wireless power transfer achieves the same efficiency as a wired connection.

The efficiency metric would need to take into account the number of cars it can charge at a given time and things like that also.
