Hi Peri,
I haven't seen any projections from the industry that would indicate
200KW would be necessary - however, you do raise some good points. I'll
see about getting those values into the specs.
Cheers, Peter

Peter,
Considering that the current level 3 chargers do about 60kW and Tesla's
supercharger will be 120kW, it seems that 75kW or even 100kW is still low
for future planning.
If someone wants to make a 300 mile trip, they're going to need to recharge
somewhere along the way. Early adopters won't mind waiting an hour to
charge, but I wonder if mainstream people would trade in their ICE with
charge times that long.
For example, to charge a 50kWh battery in 15 minutes, one would need a 200kW
connection. I'm concerned that we'll be spending a fortune on
infrastructure only to find it becomes outdated by the time it is installed.
Am I being too optimistic or is that still beyond what the standards group
thinks is going to be needed in the next 10 years?

Hi Peri,
I feel extremely lucky - I mean I built my own electric 914, and work in
a company that provides free charging, and now I'm getting to work on
wireless EV charging. :)
As for the timeframe of the standard, I really don't know when it would
become "reality". I suspect that by the end of next year it should be
solid, perhaps even published.
What the standards groups are planning for is power ranges up to 75KW or
even 100KW. There are several companies that are content with 3.3KW, but
my personal opinion is that this is entirely too short-sighted. We
shouldn't have to change the interconnects if we are going to shove more
power through.
Cheers, Peter

Peter, you are lucky to be in such a critical place of influence! How far
in the future are standards being designed for? My quip has been that
what
we have today will be inadequate once batteries can hold enough energy for
200+ miles per charge. A whole new set of charging interconnects may be
needed, perhaps like what Tesla has. I'd like to hear your thoughts on
this.
