Daytime charging while enroute makes no sense to me and it will fairly soon be obsoleted by longer EV range and standardized battery exchange. (EREV will similarly be obsoleted, but is currently the way to go for many of us.)
I disagree. I think that stopping en route is actually preferable. You're going to do it with a gasoline vehicle (even if you aren't stopping for gas), but you're going to do it for the convenience and health of your passengers.
I think the bigger issue is charge speed. This has been a hot topic for a while, so I started timing my stops for gasoline, food, and restroom breaks. What I found was that I (without a discernible hold up... long lines, poor service, etc.) was spending about 20 minutes at any one stop. Tack 10 minutes onto that, and you've got nearly 100 miles of charge... and that's in a Bolt.
IMHO even a Tesla MS60 should still be considered an urban vehicle, same as the Bolt. Even with their SC network many MS60 owners think they can easily travel cross country.
I was going to buy a Tesla CPO but could only afford a MS60, after playing with EVTripPlanner.com for the three destinations/routes I'd want/need to take during the year proved one was totally undo able and the other two could only be done in temps above 45 degrees, unless I was willing to stop at EVERY SC along the routes.
I think the newer S60 that is a software restricted S75 is a better option, and for road trips, it is ironically every bit as effective as an S75. The reason for that is you are able to accept higher charge rates up to 100% charge, so in this guy's situation, he would have had 200 miles of range in less than an hour.
That is no different than what Motor Trend uncovered when they tried to charge the Bolt to 100% on a DCFC charger and it took over two hours. People are going to need to start changing their mentality. An EV isn't a cell phone. You don't need to wait for it to hit 100% before you unplug it every time. In fact, it will be better for your time and the battery's life if you unplug it at 80% every time.
