How many transformers do you see? It is not one per dwelling/shop. Another such as this small load can feed off an existing transformer much like street lights. It will take some Electrical engineering by people such as myself, but I think it is doable.

Take a look BEHIND the businesses...there's a transformer every 3rd or 4th door.

You run the cable from the transformer to the charging station, it does not feed off the dwellings meter.

my experience is that it takes a few hours to charge an electric cart so charging stations would only work if you were to leave your vehicle for several hours. Not real practical. I got tired of all that hassle and unreliablity and got a gas. Now piece of mind as far as getting back home goes.
