It does not appear that any car maker other than Tesla has put any thought whatsoever into charging infrastructure. If VW plans on having dozens of electric car models out in a (relatively) few years time, they better get working on the long-distance charging facilities yesterday, or you are going to end up with a whole lot of people not able to drive more than 300 mi in a day. For VW to be planning on a 2018-19 car that can charge in 15 min, they better be ready to spend some serious cash right-the-heck-now. Having a 15 min charge at home is irrelevant, as you can charge any EV overnight without any special equipment, so the only place that such a quick charge makes sense is on the road.
According to the US govt figures I checked, there are about 14,000 EV charging locations in the US, but only 10% of those are faster than level 2. Tesla has more fast chargers than the other types combined. I know that where I live, the closest Chademo is 60mi away, and that's the only one I am aware of. Clearly, putting in 1 super-fast charger in a city would be less than worthless, as it would ultimately be a liability for people who might have no chance to use it because of waiting for other people to finish.
