As far as I’m concerned all of these types of chargers will have a limited shelf life, as battery tech progresses charging an EV will be similar to filling up a standard ICE car. Five minutes at the charger will supply 200-300 miles range, which IMO is enough for most journeys.
Agreed – speeds of charging batteries are increasing all the time – and generally you won’t flatten the battery and then have to do a full charge so that reduces time as well.
