I'm going to guess that they are orders of magnitude safer than gas stations. Firstly: no ground pollution. Gas stations are terrible for the land they are built on as they leak lots of organic compounds into the soil. Secondarily: no large reservoirs of combustible materials. I don't know the details of the supercharging stations, but I'd guess that they are at least as safe as the electric transformers we see on telephone poles everywhere.
