That is an interesting question. Wires are expensive, and so that gantry isn't cheap - probably you want to run high voltage which implies transformers everywhere (and in turn more poles to hold them up)... Batteries are not cheaper either though. Of course we also don't know how many systems we are talking about - if only 1 car in a large parking lots needs charging that is very difference costs from every car.
I don't know where to find the numbers to work with. (I probably could). Does anyone have some real world numbers for what the costs of each are so we can compare?
