EV wireless charging will power the future of autonomous vehicles

If they can make it fast charge even better. Start a partnership with Sonic (or other drive in eatery) and charge while you wait for your carhop and food.
One issue I noticed is that there is no uniform standard for the location of the coil under the car.
I think it seems more logical to put under the front wheels as it would be easier to turn the steering wheel to put the car just above the charging coil.
If some cars have instead a coil in the middle of the car or other cars have it under the rear wheels, this will complicate the parking maneuver,
especially if you wanted to have a self parking cars where car don't need a valet to park and move themselves when they need to get charged.
Also, if you put coils in the street, so cars can parks and get charged without any risk of getting a plug or a cable to be vandalized,
in the case of parallel parking, the size of the parking spot needs to be twice as long, so depending if your coil is on the front or the back,
you need to have enough space to move to put your charging coil just above the coil located on the floor, but this is a waist of parking space.
I wonder which charging method will prevail for future autonomous self driving cars: Wireless charging or robotic arm, or both?
Wireless charging
PROS
- No moving parts
- No vandalism
- Could be installed anywhere, not noticeable, no extra space needed
CONS- No vandalism
- Could be installed anywhere, not noticeable, no extra space needed
- Extra cost option for each car
- Cleaning issues (Can be affected by dirt, snow or any metallic object left on the floor)
- Efficiency issues, especially if the coils are not correctly aligned or if the gap is too important
(One of the two coils might need to move vertically to minimize the gap for vehicle with high ground clearance)
- Max power transfer limitation
- Coil location under the car might not uniform
- No Protocol standard or possible incompatibilities between chargers
- Possible Electromagnetic effect on human or animals passing by during operation (to be determined)

Robotic Arm
PROS
- Potentially could work with any car without any additional cost
(however, some cars have an additional cover on the DC plugs which need to be considered)
- No additional efficiency issues
- No max power transfer limitation
CONS(however, some cars have an additional cover on the DC plugs which need to be considered)
- No additional efficiency issues
- No max power transfer limitation
- Maintenance of the robot arm
- Possible physical limitation to keep simple (Work only with cars with charger door on the side
but would not work if the charger door is on the front or the rear of the car, and vice versa)
- Vandalism (But the robotic arm could lock itself inside a cabinet when not in use)
