As a retired EE, I’m confident that smarts will prevail and from qualified source of technical endeavor.

While ICE cars often do partial fill ups, a half way gives perhaps 200 miles. The BEV is going to be sorely limited for awhile, a half charge might just get you home for the overnight charge. If the range is only 40 or 60 miles like the Miles BEV, a half charge might only get you to the next charge point.

Sending the solar DC direct to the car sounds reasonable but the extra losses in taking it off the grid might not amount to much in the scheme of things (EE speaking) since grid power is far cheaper. Then you can move the solar panels back to where they belong, in a sunny climate or on top of building far from the station or better still forget them. Taking the power straight from the grid will allow many cars to charge one after the other at much faster charge rates, the grid has a very low impedance.

Granted it doesn’t make sense to have the panels not attached to the grid, but they should also consider sending the DC power directly to the car (a type of second plug) so there are fewer losses from inverting the current to and from AC.

Do the math, a Leaf with a 25KWh battery would need 4hours of sunshine at 6KW rate for a full charge, so one station might charge 2 BEVs/day if it could buffer enough sunshine, maybe almost nothing in winter.

This is like saying the grid would work even better by cutting it up into tiny isolated pieces and not letting energy flow between the parts.

What we need in the north east is a strong common baseload grid best made of concentrated power sources. Preferably not coal of course, but that means gas, nuclear or renewables, all of which have their issues.

Its as if fools are designing the new power systems of the future and ignoring the advice of engineers and physicists.

What these blogs need to be discussing is next generation nuclear that is orders more efficient than the ones in operation today and get over the 3 mile island elephant. Coal puts out far more radioactive emissions than nuclear plants.
