“Wonder what the charging rate is?”

Well think of this, how big is a wireless charger compared to the phone that it’s charging? Now scale it up to charge a car (or a fleet of cars) and you have some idea of what they are proposing here. Or I have an idea, stick to a regular car that I can refuel wherever I run low and I can do it in 10 minutes.

The coil is only about 1 inch square. Most of what you see is for supporting the phone.

Scaled up about 1 meter square.

Imagine never having to refuel!

I wonder about the power loss in those inductive coils and the battery they charge. Such coils are basically the primary windings of a transformer. The secondary is on board the train producing AC to the Power Electronics Unit. The power losses of a transformer Then consider the power loss (20%) with the Power Electronics Unit which converts the AC to the DC battery charging voltage along with the cooling fans and other parasitic loads. Then consider the power losses from charging the battery and its discharge losses.

In the big picture, consider the power losses (about 5%) from the infrastructure needed to deliver the power to those inductive charging coils.

Think of this as well: any current generates an EM field. What is a charger of this size going to do to any other electronics in the vehicle? Any nearby electronics on pedestrians?
