I wouldn't be so sure of that.  Three modern houses have a maximum power 
capacity of 144kW, within hailing distance of 150kW.   

Admittedly it's pretty unusual for a house to max out its service, and for 3 
in a neighborhood to do so would be really extraordinary.  But consider that 
some "mcmansions" have 96kW service.  I'm sure they wouldn't have paid the 
extra installation bill for that big a service if they weren't exceeding 
48kW on a regular basis.  (That's a staggering amount of power for any one 
family to be sucking from the grid, BTW.)

Or are you perhaps mixing up kWh and kW, and expecting to charge a 150kWh 
battery in less than an hour?  In that case you would need more than 150kW. 
That's a different problem, but I wouldn't call it impossible to solve.

Any time you go on a long trip.

Another way of looking at this is that every time we increase range, the 
customer moves the goalposts (to mix metaphors).  As soon as most EVs have 
300 mile range, they'll insist they need 400 miles, and so on.  I doubt that 
any of them will be satisfied until EVs have as much range as ICEVs and can 
be "refueled" at least as quickly.  Even then they'll no doubt find some 
other reason that EVs just aren't good enough.
