Wonder how much it would cost to built a 0% loss robotic charger?

All one would need is an arm with a plug on the end and the ability to move the arm in three directions (right/left, up/down, in/out). Targeting the car’s plug should be easy. For example, use a small flashing IR light such as found on a remote control as a guide.

Were we to roughly standardize plug placement on EVs then one could drive up to a charging station and push a button. The charging port would open and the light start flashing.
