There's probably a link somewhere. I don't remember the exact figure for Halo efficiency but I was pleasantly surprised how high it can be.

At best it's in the low 90's and that's at charging levels that are a fraction of a "wired" connection which is close to 100% efficient.

The end-game should be a car with gasoline-powered fuel cell, with Halo and small pit-stop batteries and electric motors in each wheel, with regenerative braking, all integrated with mobile Cyberspace for interactive management of the 3D realm of other vehicles, roads and pedestrians. The cars would be autonomous [no large stupid primates allowed to hold onto the steering wheel which would be obsolete. Maybe there would be a joystick for manual control in some situations. Upper surfaces would have photovoltaics.

Fuel cells are just too inefficient.. Just not going to happen even if they were free.

Most pure electric and hybrids already have regenerative braking. Battery swaps are not going to happen at any real scale. With battery development happening rapidly now there will be virtually no need for it.

Electric motors in wheels sounds sexy but just too inefficient, adds weight to the car, wiring problems, separate invertors required to drive each motor... DC motors maybe but they weigh more than AC induction motors for the same power.

Study some of Tesla's white papers on the subject. An excellent resource.

You should try driving one. They are a lot of fun. Not to mention very, very efficient and clean. Absolutely no emissions if you have your own PV array which a number of Tesla owners already have in place today.
