"SanDust"...you can't account for opportunity charging in a reliable way...
Since your comment is largely fallacious, as per your usual practice, I will reply to the single kernel of truth above.
I drive a BEV.
I do not often
"opportunity charge", because it is, in the form of public L2 1772s, not only unreliable, but extremely expensive as well, though I, like virtually every EV driver, have never had to pay the true cost of the service, myself.
I do make trips beyond my single-charge range, especially when there is a convenient 240V source I can count on for a
necessary charge.
Other EV owners might consider it disadvantageous to live in an area where the "opportunity charging" J1772 L2s are nearly non-existent.
But about 95% of my miles are within my LEAF's single charge range. For the occasional longer drive, I use Phil's excellent modified Panasonic 16 amp EVSE. Almost everyone I know has a 240 V electric dryer outlet in their home. I am also fortunate to live in an area, where most people only get to visit while "on vacation". So where I take longer trips, there is already a dependable, and fairly extensive 240V infrastructure, in the form of RV parks, often in scenic locations. I've found park owners are generally happy to make a few bucks, and, on the relatively rare occasion I do need a charge away fom my (or a friend's) home, I usually get a much nicer place to wait for a slow charge, than a Walgreen's parking lot.
Of course, DC charge stations will probably, sooner or later, end most of the short-stay-L2-charge business for RV park owners, and the market for public J1772 L2s, and (back on-topic) PHEVs, as well.
