There's already fast/flash charging work in place for buses in many cities:

A few seconds and the bus gets a fast top up whilst it sets passengers down and goes onto the next stop. If smaller, lighter cars can be engineered to absorb this kind of big charge in a short period of time without manually connecting the EV it could be revolutionary.
Awesome to see great engineers from the top car companies clubbing together though. It should accelerate the research and development.
