I honestly believe that 90 kW (or greater) charge rates are needed to support long distance travel - I don't think that 50 kW chargers will suffice.
That really depends on
why you're traveling long distance. If it's a business trip where time is money and you're trying to cover as much ground as possible in as short a time as possible then yeah, I agree.
But for vacation travel where you're going to need to stop for lunch somewhere and maybe take in a sight or two along the way, a 50KW charger that gets you 80% of the Bolt's range in an hour is pretty doable, IMHO. Topping up your charge at lunchtime and then getting a full L2 charge overnight gives you about 600km (5-6 hours) of realistic daily driving, which is a pretty decent amount of travel.
IMHO the availability and spacing of chargers along the route would be a more important consideration than >50KW charging, because busy/broken chargers coupled with large gaps in coverage would seriously compromise how far you could go and how often you'd have to stop to get an "insurance" top-up just in case the next charger isn't available. Fortunately, coverage gaps are steadily being filled in, at least here on the west coast, making road trips a very viable possibility.
Of course if you're in the heartland then you're SOL...
Personally, when I travel long distances I travel
more than 400 miles in a day - and not for business. I visit family in OR or WA, and I like to do the drive in one day (or 1 1/2, when going to Yakima). I do
NOT want to spend 1/4 of my travel time waiting to charge the damn car! Heck, I don't even want to do that when driving up to Reno from San Jose to visit my sister, and that's 'only' 300 miles. While I *do* stop for bathroom breaks, and coffee, and sandwiches (and gas), I do
not stop for an hour. In fact, the bathroom & coffee breaks are generally during the gas stops anyways. And I'll probably stop a few times to get out of the car and walk around for 3-5 minutes. That is
five minutes, however. That is a FAR cry from stopping for an hour every 3 hours! I imagine it would be worse with small children. "Just wait 15 minutes honey bear, and you can walk around all you want, we'll be at the next stop for 45 minutes anyhow!". My wife would have *loved* the car trips with the little-uns even more! :roll:
In my experience, the existing 50 kW chargers are NOT located in spots where one would normally choose stop for an hour during a trip. I have NEVER seen a DCFC in a national forest or recreational area, or any 'tourist spot'. When they are near restaurants, they tend to be fast food crap (dennies, long john silvers, burgers) because they are in MALLS (although, interestingly, in Vegas there is a gas station chain installing them) or car dealerships. About
ten Super
Quick (SQ) charging installations (with 6-16 charge bays) would cover the
entire state for long distance travel. And CA is the third largest state!
90 kW is well within the current standards - there just aren't any chargers or cars that currently do it (besides Tesla). And the consortium for CCS (CharIN e. V.) are working on version 2.0 of the standard already : backwards compatible, charge at 150 kW rate using same plug (existing cars will get charged at 50 kW, existing 50kW chargers will charge cars that accept CCS2.0 rates up to 150 kW). There is talk that it will be rolled out in 2017.
Frankly, I think that the most important thing missing from the Bolt is
Super
Quick charging. There's not much of an incentive for me to trade in my 80 mi range SparkEV for a 220+ mi range Bolt, since realistically I won't be using the additional range that often, and I won't use it on long trips. I might get a used one (lease return) in 3-4 years just so that I don't have to stop at a DCFC to go to San Francisco or Monterey. But honestly, my Spark will handle 97% of the trips, and 90% of the miles that my family drives. When we drive further than 60 miles away (120 mi or further round trip), we use a gas-mobile. That's maybe once every 2 months (trips to SF are electric, as there are over 10 DCFCs between me & SF, and I only need to add 40 miles or so, about 10 mins).
