Charging a car-sized battery in 5 minutes requires nearly a megawatt of power. Even if this tech becomes widespread in cars I highly doubt the infrastructure will ever be in place for it be something that the average person can use on a regular basis. It seems likely that when EVs become the norm people will mostly use slower charging while parked and pay extra for fast charging on long distance trips only. But widespread adoption will still probably require some fairly significant upgrades of power generation infrastructure.
