@sudolea, hmm. I can't help you any further than this:
You might want to check openchargemap.org. It's a public worldwide database with an API which I think you could use to get the wanted data as KML file. You will however need to convert that into OV2, GPX or CSV.
Many services seem to be commercial, it is not easy to find a ready to use POI for fast chargers I think.
